Description

Technical Field

[0001] The present invention relates to the technical field of stepless speed regulation and power load adaptation, such as stepless speed regulators, power distribution / convergence devices, dual-path / multi-stage power allocation devices and energy recovery devices in rotating power and its load systems (such as fans, pumps, various transportation vehicles and various mechanical equipment, etc.), and to a power regulation / speed regulator and its super energy-saving system that integrates some or all of the functions of stepless speed regulation, torque conversion, energy recovery, power mixing, distributed power configuration and stepless power allocation, and in particular, a stepless speed regulator and its energy-saving system based on a differential transmission / power converging mechanism. Background Art

[0002] In the past decade, the rapidly developed permanent magnet coupling speed regulator has gradually been recognized by experts and the market in the field of centrifugal load speed regulation, energy saving and emission reduction, but it also has obvious shortcomings and deficiencies. Since 2009, the inventor has successively obtained authorization for more than ten invention patents in the field of permanent magnet coupling speed regulator, and self-raised funds to build a factory and form mass production. It has been widely used and well received in the energy saving and emission reduction of industrial centrifugal load systems (fans, water pumps, etc.), making great progress in the energy-saving technology level. However, in the process of promotion, it is gradually realized that the permanent magnet coupling speed regulator has many advantages, but it also has the following shortcomings that are difficult to overcome: First, because its active and passive disks are air-gap coupled cantilever beam structures, and are subject to the design limitations of the axial installation size of the equipment, it is bound to produce severe vibration and noise under high power and / or high speed conditions. The noise makes the system reliability relatively poor; secondly, the system efficiency is low, especially under the conditions of low rated speed, high power and more speed reduction, the energy proportional to the percentage of speed reduction will become a large amount of heat consumed on the metal conductor disk, and the average actual working total useful efficiency of its power load system is generally less than 60%, especially for high-power models, because the system needs to add cooling devices, the cost also increases, and the reliability is greatly reduced; thirdly, it can only adjust the speed down, not the speed up; fourthly, the speed regulation accuracy is relatively low; fifthly, there is no torque conversion or self-locking function between the active (power) shaft and the passive (load) shaft, and the application is greatly limited.

[0003] High-voltage, high-power motor inverters are also widely used in the field of energy conservation and emission reduction of centrifugal load systems. However, due to high requirements for the operating environment (constant temperature and humidity), they occupy a large space, have poor reliability, and consume a lot of energy. Due to the constraints of their working efficiency characteristics, the average actual working total useful efficiency of power load systems in most frequency bands is significantly lower than the rated efficiency, generally less than 60%. Inverters also produce serious power harmonic pollution, and high-voltage inverter equipment is expensive, requires special maintenance, has huge operating costs and many other shortcomings, and is also widely criticized.

[0004] Hydraulic coupling speed regulators are also widely used in adjustable centrifugal load and non-centrifugal load systems (such as fans, water pumps, ball mills, feeders, conveyor belts, tunneling machines, drilling machines, elevators, air compressors, etc.). This is because the average actual working total useful efficiency of their power load systems is relatively lower, and their speed regulation range is small. The loss of hydraulic medium consumables is large and it pollutes the environment, which makes the technology even more backward.

[0005] The above-mentioned traditional speed regulator energy-saving technology is only applicable to the "big horse pulling a small cart" system, which is not conducive to improving system efficiency and causing waste of resource allocation. On the other hand, for high-power systems, during the load speed reduction adjustment process, it can only reduce the power consumed by the load, but cannot improve the output efficiency of the power system. It will also cause the power system to significantly reduce the working efficiency, making the system energy consumption and heat generation serious. These heats are not only difficult to recycle, but also need to be equipped with cooling devices. While greatly increasing the cost investment, the system reliability is also significantly reduced. In other words, for the current large-scale power load system, especially large-scale centrifugal equipment such as fan pumps, even if energy-saving equipment such as frequency converters, permanent magnet speed regulators, and hydraulic couplings are installed, the average actual total useful efficiency of the power load system will generally not exceed 65%, or even lower, which is a huge waste. In addition, due to the matching problem between power and load in common power and load systems, serious energy or power waste will also occur. Therefore, in order to solve the long-standing "difficult" problems in the above-mentioned energy-saving and emission-reduction technology fields, traditional speed regulation / speed-changing products and their energy-saving and emission-reduction technologies are in urgent need of innovation, and comprehensive measures should be taken to address the existing "pain points". It is very necessary to develop and produce a new generation of stepless speed regulation based on differential transmission / power confluence mechanisms and stepless speed regulators and their energy-saving systems based on differential transmission / power confluence mechanisms. Summary of the invention

[0006] The present invention attempts to fundamentally solve the shortcomings and problems of the above-mentioned traditional automatic transmissions, permanent magnet coupling speed regulators, frequency converters and hydraulic coupling speed regulators, and at the same time integrates practical speed regulation, torque change, soft start, dual-channel (or multi-channel / multi-stage) rotational power synthesis, convergence / divergence between power sources, power regulation, and energy recovery during deceleration / braking / downhill. It is a multi-functional machine that can not only achieve stepless speed regulation and torque change, but also has higher-level power convergence / divergence, energy recovery and power regulation and deployment capabilities. The present invention includes a variety of optional technical solutions, and the technical solutions are selected according to actual needs or the number of functional modes. That is to say, whether the present invention is applied to the transformation of an existing power load system or to a new power load system, there are targeted or technical solutions with different configurations that can be selected to achieve the purpose of technological improvement and progress. On the one hand, the present invention includes various technical solutions with different configurations based on the power configuration concept of "doing the best, giving enough and consuming less, giving more and then recycling"; on the other hand, the present invention also includes a variety of technical solutions with different configurations built with a more advanced and innovative energy-saving concept of "doing what one can, giving as much as needed, and never wasting" as the functional goal, so as to abandon the traditional "big horse pulling a small cart" that must be followed due to the need to meet the cold start, that is, "the rated power of the power source ≥ the rated power of the load (1+the power redundancy factor of the system required for cold start 15-20%), the rated power of the speed regulating energy-saving equipment ≥ the rated power of the load The traditional power configuration scheme of "rate" is used to establish an innovative energy-saving power load configuration scheme, namely "rated power of main power source + rated power of power regulation / speed regulation motor ≥ rated power of load"; in addition, the present invention also includes that according to actual needs, or to solve the situation where ultra-large power power equipment is difficult, at least two power sources, namely hybrid / distributed power configuration schemes, are used to solve the problem of driving ultra-large loads, or to solve the problem of high energy consumption of under-load operation of "big horse pulling a small cart" under load conditions that change at any time, especially for large or ultra-large power equipment, the overall operating efficiency of the system is seriously reduced due to the reduced speed operation. In summary, the present invention opens up a new and complete technical solution for energy conservation and emission reduction, and makes it possible to build a super energy-saving intelligent power load system.

[0007] It is more intelligent, more functional and innovative in the following aspects: First, during the startup process, the main power source does not work first, and the power regulation / speed regulation motor works first to realize the load soft start function; second, during the normal operation of the power load system, the output speed and torque of the power regulation / speed regulation motor are controlled, and the purpose of adjusting the load speed and power is achieved through the power confluence mechanism, so as to solve the problem that the speed reduction caused by the application of traditional energy-saving technologies in constant speed power systems will lead to reduced system efficiency and serious energy consumption; third, especially in the variable frequency energy-saving system of high-voltage and high-power power loads, since the power regulation / speed regulation motor can use a different voltage level and a smaller power model from the main power source, it is easier to use high-reliability and low-cost medium and low-voltage power regulation / speed regulation motors and their inverters, and it is easier and more cost-effective to realize energy-saving transformation of traditional high-voltage and high-power motor systems, and to build large-scale more reasonably and intensively. The resource allocation of the power system of the load; Fourth, distributed hybrid power can be used to replace a single main power source to provide power for large loads, making the power configuration scheme of large loads more diversified and more conducive to improving the rationality, safety and reliability of power supply; Fifth, generally speaking, for large power sources (such as electric motors, etc.) working under underload (less than the rated power output), the smaller the actual output power, the significantly lower the efficiency. The power configuration scheme of "main power source + power regulation / speed regulating motor" of the present invention eliminates this disadvantage, making it possible for power equipment to work efficiently under all-weather conditions; Sixth, in industrial and agricultural production and various fields of social life, there are many large and medium-sized centrifugal equipment (such as fans, pumps, etc.) energy-saving fields. The technical scheme of the present invention can increase the total energy-saving efficiency of the system by at least 30%, and has broad application space and market prospects. It is easy to see that the speed regulator based on the power confluence mechanism of the planetary gear set provides important technical support for energy saving in terms of energy saving for the construction of a super energy-saving power load system based on the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation theorem. It should be pointed out that the power types of the main power source described below are diverse, and any rotating power source can be selected, such as electric motors, internal combustion engines, steam turbines and water turbines. Of course, it is not ruled out that in some application conditions, the main power source can also be selected to be the same type as the power regulation / speed regulation motor described. Such a selection result is more convenient for equipment maintenance and emergency replacement, or, by operating the control switching switch device, the main power source power regulation / speed regulation motor and the power regulation / speed regulation motor are controlled by a shared control driver / frequency converter in a time-sharing / combination manner, which is convenient for establishing a combined control and control switching function that meets special needs.

[0008] In the application scenarios of power load equipment in social life and industrial and agricultural production, the specific speed regulation range can be designed and determined according to different working conditions and process requirements. The common "main power source + power regulation / speed regulation motor" configuration scheme and its working module / mode list are as follows for real-time system call operation:

[0009] In order to meet the main power source rated power + power regulation / speed control motor rated power ≥ load rated power

[0010] Assume that the rated power of the main power source ≥ K% * rated shaft power of the load,

[0011] Wherein K<50 to 100 is optional, and generally 60 to 75 is preferred;

[0012] Correspondingly, the rated power of the power regulation / speed regulation motor ≥ (1-K) * rated shaft power of the load:

[0013] Soft start & stepless speed / power adjustment range 1: from 0% to K%;

[0014] Stepless speed increase / power adjustment range 2: from K% to 100%;

[0015] Stepless speed reduction / power adjustment range 3: from K% to 0%.

[0016] ① Soft start module, the speed regulator works in the "soft start & stepless adjustment range 1" state. Before the main power source is put into operation, the power adjustment / speed regulation motor is started to output positive torque from small to large, driving the load to start slowly, and then the main power source is started to make the load speed from low to high, start smoothly, and transition to normal operation. This can greatly reduce the extraordinary starting power required for rapid start of the load; especially for high-speed, high-inertia, and high-power load systems, their rapid start often fails and even burns the power equipment, so the soft start module is very necessary.

[0017] ② Thermal engine / light load module, the speed regulator works in the "post-soft start" state. The power load system sometimes requires the load equipment to be in low speed (light load) thermal engine idling operation, that is, the main power source is not started, the load is in a separated / no-load / light load state, and the power regulation / speed regulation motor continues to work and outputs positive torque, driving the load to idle at a load speed less than or equal to the rated power of the power regulation / speed regulation motor.

[0018] ③ Basic operation / direct drive operation module. Generally speaking, in order to take into account the two factors of "small system construction investment and good energy-saving effect", the rated power and speed of the main power source are determined according to the most basic load shaft power and speed in the most common load condition / process. At this time, the power regulation / speed regulation motor is in a static state or its transmission shaft is in a "0 speed, high torque" braking state. It does not output the regulated power and only relies on the main power source to output the rated power and speed to maintain the load at the most basic (or minimum) and most common working condition / process rated power and speed.

[0019] ④ Stepless speed increase / power increase operation mode, at this time, only the normal rated power of the main power source can no longer meet the load power / speed increase requirements of the working condition, and the power adjustment / speed regulation motor is set to the motor working state, that is, the power adjustment / speed regulation motor is put into operation and outputs positive torque (torque in the same direction as the positive speed of the load). According to the working condition requirements, the output power / torque of the power adjustment / speed regulation motor is adjusted in real time, and the power of the stepless speed regulator based on the differential transmission / power confluence mechanism is combined to jointly drive the load equipment to work until the rated power / torque of the main power source + the rated power / torque of the power adjustment / speed regulation motor ≥ the rated shaft power / torque of the load. When the system works in the "stepless speed increase adjustment range 2", the main power source runs at the rated power and speed, and the power adjustment / speed regulation motor is put into operation at the power and torque / speed set by the control adjustment. The sum of the two powers is equal to the load shaft power of the real-time working condition. According to the working condition process requirements, the power adjustment / speed regulation motor is controlled to output the adapted power power and speed, so as to achieve the purpose of "giving as much as needed and never wasting" the load power. At this time, the main power source and the power regulating / speed regulating motor drive the planetary gear to rotate and revolve through the power input end / shaft and the power regulating end / shaft of the speed regulator respectively, and the rotation torque and the revolution torque of the planetary gear are superimposed on the power output end / shaft of the speed regulator in the same direction, that is, the output power of the main power source and the power regulating / speed regulating motor are merged to the output end / shaft of the speed regulator, so that two or more (multi-stage series) distributed powers can work together to drive the load to work.

[0020] ⑤ Speed ​​reduction / emergency adjustment operation mode - non-power recovery speed reduction operation mode. Generally speaking, there are power braking and speed reduction losses in this mode. It is common but not limited to emergency operation. The speed regulator works in the "stepless deceleration adjustment range 3" state. The main power source runs at the rated speed. When the load speed needs to be reduced, or when encountering abnormal emergency load speed requirements under special working conditions, the power adjustment / speed regulation motor is started and set to negative torque (torque opposite to the positive rotation direction of the power adjustment / speed regulation motor driving the load). That is to say, while the main power source runs at the rated speed, the power adjustment / speed regulation motor is controlled and operated to run with reverse braking power and torque / speed. The difference between the two powers is equal to the load shaft power under the emergency real-time working conditions. The power adjustment / speed regulation motor is controlled to output the appropriate braking power as needed to cause the load to slow down, and at the same time, the energy-saving effect of load speed reduction can be obtained. At this time, the main power source and the power regulating / speed regulating motor drive the planetary gear to rotate and revolve in the opposite direction through the power input end / shaft and the power regulating end / shaft of the speed regulator, respectively. The rotation torque and the revolution torque of the planetary gear are in opposite directions, and the braking torque in the opposite direction is offset to the power output end / shaft of the speed regulator, that is, the difference in output power between the main power source and the power regulating / speed regulating motor is converged to the output end / shaft of the speed regulator to meet the emergency speed reduction operation requirements of the load. This module is only set up to meet the occasional needs when special working conditions and process requirements arise. The reason is that under this working module, in order to meet the system energy saving of the speed reduction working condition of reducing flow and pressure, especially for centrifugal loads, because the real-time shaft power of the load is proportional to the cube of the speed, even if a little braking power of the power regulating / speed regulating motor is consumed under this module, the overall energy saving effect is also good. The solution to reduce the operating frequency of the module is to reduce the rated power configuration of the main power source and increase the rated power configuration of the power regulation / speed regulation motor. In this way, the system cost will be higher, but the speed regulation range of the more energy-saving "normal stepless speed regulation range 2" will be larger. According to the equipment configuration principle shown in the present invention, the favorable energy-saving and low-cost factors under various working conditions are comprehensively considered to build a more reasonable stepless speed regulator.

[0021] ⑥ Stepless speed reduction / load power reduction - power recovery speed reduction operation mode, at this time the main power source works normally, and starts the power regulation / speed regulation motor to work and output negative torque (torque opposite to the positive speed of the load), that is, the power regulation / speed regulation motor works in the generator state and becomes a power regulation generator. The main power source is powered by a stepless speed regulator based on a differential transmission / power confluence mechanism. A part of the main power source output power or torque drives the load equipment to work at a lower operating speed through the power output end of the stepless speed regulator based on the differential transmission / power confluence mechanism, and another part of the main power source output power or torque is allocated to the power regulation generator through the power regulation end of the stepless speed regulator based on the differential transmission / power confluence mechanism to drive power generation. The power output is fed back to the electric power equipment for use through the corresponding circuit of the controller, or provides power energy to the internal / external power grid, or supplies power to storage equipment or other power loads.

[0022] This case is based on and utilizes the working mechanism of planetary gear differential transmission and power confluence / power distribution transmission mechanism, and uses the minimum energy consumption principle, lever principle, gear transmission principle and energy conservation theorem as well as the adjustable load speed regulation energy saving principle to deeply explore the correlation and interaction between the differential and power confluence / power distribution among the left and right half-shaft gears and the planetary carrier (planetary gear differential case) of the differential transmission mechanism, and realize the function of three-dimensional energy adaptation, distribution or mutual control, and give the planetary carrier, left half-shaft and right half-shaft of the power distribution / differential transmission mechanism new design concepts and functions, and thus construct a stepless speed regulator based on differential transmission / power confluence mechanism with different uses and functions. In this case, the planetary carrier, left half-shaft and right half-shaft can be used as the power input end, power regulation end or power distribution / distribution / adaptation end respectively. The difference lies in the different energy transmission paths, and the distribution torque transmission ratio and speed ratio between input and output will be different. That is to say, one of the two left and right half-axles is used as the output end / shaft of the stepless speed regulator based on the differential transmission / power confluence mechanism; one of the other half-axles and the planetary gear carrier is used as the main power input end / shaft, and the remaining one is used as the power adjustment end / shaft and is connected to the rotor / rotor shaft of the power adjustment / speed regulation motor (referring to a motor with real-time online two-way controllable motor / generator function). The stepless speed regulator based on the differential transmission / power confluence mechanism in this case can be used in a single stage or in a multi-stage series / parallel setting, so as to invest more power sources or combine them into a more flexible, diverse and powerful working mode.

[0044] Example 1

[0045] like Figure 1 and Figure 2As shown, a stepless speed regulator based on differential transmission / power converging mechanism is an embedded stepless speed regulator based on asymmetric axial cylindrical planetary gear differential transmission / power converging mechanism. The asymmetric axial cylindrical planetary gear differential transmission / power converging mechanism (differential transmission / power converging mechanism is called differential or differential machine in some common technical fields such as automobile field, and is called power divider, power divider, power converging mechanism, power splitting mechanism, etc. in transmission technology field. They have different structures in different application fields, but their working mechanisms are similar) is integrally embedded in the hollow rotor of the power regulation / speed regulating motor. It mainly consists of four axial cylindrical planetary gears (107 and 116) power converging mechanism. The invention is composed of a flow mechanism component (101, 102, 103, 105, 106, 107 and 116), a stator component (120, 121, 122, 123, 124 and 133) of a permanent magnet power regulation / speed regulation motor and a permanent magnet hollow rotor component (130, 131, 132, 113 and 114), a speed regulator accessory (126, 110, 115, 125 and 138), a corresponding power regulation / speed regulation motor control driver / vector control inverter and a motor speed encoder (not shown).The axial cylindrical planetary gear differential transmission / power converging machine assembly is composed of four cylindrical planetary gears (107, 116) on the upper, lower, left and right sides, a straight / direct-sell type planetary gear shaft (105), a planetary gear carrier (101), a left half-shaft gear / cylindrical internal gear ring (102) and a right half-shaft column gear / cylindrical external gear sun gear (103), and the four straight / direct-sell type planetary gear shafts (105) are all connected to the center of the left and right half rotor shafts (109, 129). The axes are arranged in parallel, and each cylindrical planetary gear (107 or 116) is respectively meshed with the right half shaft cylindrical external gear sun gear (103) and the left half shaft cylindrical internal gear ring gear (102). The left half shaft (102) is used as the power regulating end of the stepless speed regulator and is connected to the rotor (130) body as an integral structure. The right half shaft (129) is used as the power output end / shaft of the stepless speed regulator and also serves as the right half rotor shaft (129). It is connected to the right rotor end cover (114) and The isolation / support bearings (115, 125) of the stator end cover (124) are arranged as the right half rotor shaft (129) of the shaft system of the hollow rotor of the power regulating / speed regulating motor, the cylindrical planetary gear carrier (101) is used as the power input end of the main power source, and is adapted to be connected with the left half rotor shaft (109) using a shaft key (136), and the isolation / support bearings (110, 126) of the rotor end cover (113) and the stator end cover (133) are arranged as the power regulating / speed regulating motor. The shaft of the permanent magnet hollow rotor (130) of the regulating / speed regulating motor is the left half rotor shaft (109), and extends out of the left rotor end cover (113) and the stator end cover (133) to become the shaft extension (139) of the power input shaft (109) of the stepless speed regulator. Other speed regulator accessories include the stator housing / body (123), the stator core (121), the stator excitation winding (122), the rotor permanent magnet assembly (132), bolt fasteners (138), etc. The power regulating / speed regulating motor control driver / vector control type inverter is widely used in the market, and can not only control the power regulating / speed regulating motor to adjust the speed at will, but also set the power to output at a constant speed or constant torque, and can also set the speed to output at a variable power or variable torque, and can work in a variety of flexible, convenient and practical functional modules / modes such as "zero speed + braking torque".

[0046] Working mechanism: Ignoring its internal friction torque (the same below), the planetary gear carrier (101) serves as the power input end / shaft, the left half-shaft gear ring (102) serves as the power adjustment end, and the right half-shaft sun gear (103) serves as the power output end / shaft. According to the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation theorem, the four planetary gears are equivalent to four equal-arm levers acting simultaneously, and together with the left and right half-shaft gears, form a set of asymmetric planetary gear transmission mechanisms. It is easy to see that the main power source rotates clockwise and the speed is constant. The left half shaft power input end / shaft (139, 109) drives the planetary gear carrier (101) to rotate clockwise. The planetary gear carrier (101) drives the four planetary gears (107 and 116) to revolve around the sun gear (103) clockwise on the one hand, and to rotate counterclockwise on the other hand, and at the same time drive the left half shaft gear / cylindrical internal gear ring (102) and the right half shaft column gear / cylindrical external gear sun gear (103) to rotate clockwise respectively.

[0047] If at this time, the power adjustment / speed regulating motor is controlled so that the hollow rotor (130) applies positive torque to the left half shaft gear ring (102), this torque will accelerate the counterclockwise rotation speed of the four planetary gears, and will also drive the right half shaft sun gear (103) to increase the clockwise torque, thereby accelerating the clockwise rotation speed of the right half shaft sun gear (103), forming a power confluence between the planetary gear carrier (101) and the left half shaft gear ring (102), achieving the purpose of increasing the speed of the power output end / shaft (129) of the right half shaft sun gear (103), which is equivalent to working in the speed increase adjustment operation mode;

[0048] If at this time, the power adjustment / speed regulation motor is controlled so that the hollow rotor (130) applies a reverse torque to the left half shaft gear ring (102), or the left half shaft gear ring (102) is rotated in the opposite direction, the reverse torque will cause the four planetary gears (107, 116) to reduce the counterclockwise rotation speed or offset the rotation torque, thereby braking the right half shaft sun gear (103) or reducing the clockwise rotation torque, that is, forming a braking torque, so as to achieve the purpose of stepless speed reduction of the power output end / shaft (129) of the right half shaft sun gear (103), which is equivalent to working in the speed reduction / emergency adjustment operation mode.

[0049] This embodiment is a device that combines the power addition / subtraction of the power adjustment end / shaft and the power input end / shaft to the power output end / shaft, so that the total output power of the main power source and the power adjustment / speed regulating motor is combined to the output end / shaft of the speed regulator, thereby achieving the purpose of real-time stepless speed regulation of the load. The power adjustment / speed regulating motor control driver / vector control inverter has the following five working modules / modes for calling: ① soft start mode ② hot engine / light load mode ③ basic operation mode ④ stepless speed increase operation mode ⑤ speed reduction / emergency regulation operation mode.

[0050] It is easy to see that the power input end / shaft, the power adjustment end / shaft and the power output end / shaft can be regarded as a causal adjustment relationship, that is, adjusting one or / and two of the factor variables, even the third factor variable will change accordingly. For example, for a centrifugal load system, when the speed changes, its load power changes exponentially to the third power, and the power power will be significantly reduced. This is also the most important mechanism for industrial energy conservation and emission reduction. After achieving a balance in the energy transfer relationship between the three, the desired and compatible power input and output end / shaft operating speed, torque or / and shaft power can be obtained, so that the system can respond in real time in different modes and achieve the most energy-saving working state, so as to meet different working condition process designs, working module / mode control processes and actual emergency needs, and achieve the best practical effect of the present invention. The conclusion of this working mechanism is also applicable to the following embodiments.

The right half-shaft (229) is used as the power output end / shaft, and is arranged as the right half-rotor shaft (229) of the shaft system of the hollow rotor of the power regulating / speed regulating motor through the isolation / support bearings (215 and 225) of the right rotor end cover (214) and the stator end cover (224) adapted on the right side, and extends out of its right rotor end cover (214) and the stator end cover ( The left half shaft (209) is used as the power input end / shaft, and is configured as the left half rotor shaft (209) of the hollow rotor of the power regulating / speed regulating motor through the isolation / support bearings (210, 226) of the rotor end cover (213) and the stator end cover (233) on the left side, and extends out of the left rotor end cover (213) and the stator end cover (233) to become the power output shaft (229) shaft extension (249) of the stepless speed regulator based on the differential transmission / power converging mechanism. The shaft extension (239) of the power input shaft (109) of the stepless speed regulator of the mechanism and the planet carrier (201) serve as the power regulating end and are arranged as an integrated structure or phase transmission connection with the hollow rotor body (230) and the rotor core (231) of the power regulating / speed regulating motor. Other accessories of the stepless speed regulator based on the differential transmission / power converging mechanism also include a stator housing / body (223), a stator core (221), a stator excitation winding (222), a rotor permanent magnet assembly (232), bolt fasteners (238), etc.

It is a differential device that can divide the torque or power of its power regulating end / axle into two, just like the differential in a car. When the planetary gear has both revolution and rotation:

[0054] On the one hand, the angular velocity formula ω 入1 +ω 出1 =2ω 调1 、Torque distribution formula M 入1 =M 出1 =(1 / 2)*M 调1 And the power formula P of energy conservation 调1 =P 入1 +P 出1 , that is, P 出1 =P 调1 -P 入1 , when the speed of the power input end / shaft is constant, it is allowed to adjust the rotation direction and speed of the power regulating end / shaft so that the power output end / shaft can obtain the desired torque, power or load speed (the formula allows the power regulating / speed regulating motor or / and the main power source to rotate in reverse or / and work with reverse torque, corresponding to negative torque, negative angular velocity or / and negative power. The same below); on the other hand, the system allows real-time setting or adjusting the positive and negative torque, power or / and speed of the power regulating end / shaft, so that the power output end / shaft can instantly obtain stepless adjustable power, torque or / and load speed, that is, the above formula allows reverse rotation or / and reverse torque, corresponding to negative torque, negative angular velocity or / and negative power; on the other hand, the system also allows the power regulating end / shaft to be set in a locked state (at this time, the power consumption of the power regulating end / shaft is 0), that is, ω 入1 +ω 出1 =2ω 调1 ,ω 调1 =0, so ω 出1 =-ω 入1 ;P 入1 +P 出1 =P 调1 , P 调1 =0, so P 出1 =-P 入1 At this time, the rotation speed of the power input end is opposite to the rotation direction of the load, and the rotation speed of the load is equal to the rotation speed of the main power source.

[0055] From the above, it can be seen that the power input end / shaft, the power adjustment end / shaft and the power output end / shaft are mutually regulating variables. By adjusting one or / and two of the variables, even the third variable will change accordingly (for example, for a centrifugal load system, when the speed changes, its load power changes exponentially to the cubic power, etc.). After the above relationship is balanced, the desired and appropriate working speed, torque and / or shaft power of the power transmission end / shaft can be obtained, thereby constructing, deploying or combining the working modes and control modules described above to make the system respond randomly and achieve an excellent working state to meet different working condition designs, working mode control processes and actual application requirements.

The planetary gears (307, 316) are respectively fixed on the planetary gear shafts (305, 345) between the end covers (313, 314), and are respectively meshed with the asymmetric left and right half-shaft gears (302, 303) with different numbers of teeth and radii. Other speed regulator accessories also include a stator housing / body (323), a stator core (321), a stator excitation winding (322), a rotor body (331), a rotor conductor cage assembly (332) and bolt fasteners (338).

[0058] In this embodiment, the left half shaft (309) serves as the power input end, the planetary gear carrier (301) serves as the power adjustment end / shaft, and the right half shaft (329) serves as the power output end / shaft.

[0059] Example 4

[0060] like Figure 6 and Figure 7As shown, a stepless speed regulator based on differential transmission / power converging mechanism is an embedded stepless speed regulator based on radial combined planetary gear differential transmission / power converging mechanism. It is composed of radial cone + circular surface combined planetary gear (407 and 416) differential transmission / power converging mechanism components (401, 402, 403, 405, 406, 407 and 416), power regulation / speed regulating motor stator (420, 421, 422, 423, 424 and 433) and hollow rotor (430, 431, 432, 413 and 414) of permanent magnet synchronous direct drive power regulation / speed regulating motor, speed regulator accessories (426, 410, 411, 417, 415, 425, 437 and 438) and power regulation / speed regulating motor control driver and state sensor components (not shown in the structural schematic diagram of this embodiment).The differential transmission / power converging mechanism is integrally embedded in the hollow rotor (430) of the power regulating / speed regulating motor, and the radial cone + circular surface combined planetary gear differential transmission / power converging mechanism assembly comprises at least one pair of cone + circular surface combined planetary gears (407, 416), a planetary gear shaft (405), a planetary gear carrier (401), a right half-shaft bevel gear (403) and a hollow left half-shaft (412) cylindrical gear (402). The planetary gear shaft (405) is radially mounted on the planetary gear carrier (401). The planetary gear shaft and the center lines of the left and right half shafts are arranged vertically, the bevel gear of the combined planetary gear meshes with the corresponding right half shaft bevel gear (403), the circular face gear of the combined planetary gear meshes with the corresponding left half shaft cylindrical gear (402), and the right half shaft (429) is used as the power output end / shaft, and is arranged to form the right half shaft of the hollow rotor shaft system of the power regulation / speed regulation motor through the isolation / support bearings (417, 415 and 425) of the correspondingly adapted planetary carrier (401), the right rotor end cover (414) and the stator end cover (424). The left half shaft (429) is connected to the left rotor end cover (413) of the power regulating / speed regulating motor through the isolation / support bearing (411) of the planetary carrier (401) and the planetary carrier (401) as the power input end. The power input shaft (409) is connected to the left rotor end cover (413) of the power regulating / speed regulating motor through the isolation / support bearing (411) of the planetary carrier (401) by the shaft key (436). The planetary carrier (401) is connected to the left rotor end cover (413) of the power regulating / speed regulating motor through the isolation / support bearing (426) of the stator. The left stator end cover (433) is sleeved in the hollow left half shaft (412) by using the shaft isolation / support bearing (410), and is connected to the one-word / direct pin type planetary gear shaft (405) and the planet carrier (401) through the shaft key (437). Other speed regulator accessories also include a stator housing / body (423), a stator core (421), a stator excitation winding (422), a rotor body (430), a rotor core (431), a rotor permanent magnet assembly (432), a structural bearing (406) and bolt fasteners (438), etc. This example uses a permanent magnet synchronous direct drive power regulation / speed regulation motor that is widely used in the market. It can not only control the power regulation / speed regulation motor to adjust the speed at will, but also set the power to output at a constant speed or constant torque, and can also set the speed to output variable power or variable torque, and can work in a variety of flexible, convenient and practical functional modules / modes such as "zero speed + braking torque".

[0061] The working mechanism is described as follows: the planetary gear shaft (405) of the planetary carrier (401) serves as the power input end, the hollow left half shaft (412) serves as the power adjustment end, and the right half shaft (429) serves as the power output end / shaft. According to the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation theorem, the bevel gear and the circular gear of the combined planetary gear are respectively equivalent to a combined lever structure or a combined gear transmission structure. As a device that can converge / divide the torque or power of the power input end / shaft, it is easy to see that:

[0062] If the system is in the soft start state, the main power source does not output power, and the power regulating / speed regulating motor rotor (413) at the power regulating end drives the planetary gears (407, 416) through the left half shaft (412) gear (402), thereby driving the right half shaft gear (403) and the power output end / shaft (429) from static to rotation, controlling the power regulating / speed regulating motor control driver, and then gradually increasing the speed to an appropriate starting speed;

[0063] If the main power source rotates clockwise and the speed is constant, the planetary gear shaft (405) and the planetary gears (407, 416) are driven by the power input end / shaft (409), thereby driving the right half-shaft gear (403) and the power output end / shaft (429) to rotate clockwise; at the same time, the rotor of the power regulating / speed regulating motor has at least five control driving working states. First, the power regulating / speed regulating motor does not output torque or its rotor is in a free state, that is, the left half-shaft (412) can be regarded as an unloaded state, and the planetary gears (407, 416) and the right half-shaft gear (403) are actually a simple first-stage gear transmission structure. The power input end / shaft (409) outputs power to the output end / shaft (429) through the first-stage gear transmission structure; second, the power regulating / speed regulating motor is in a "zero speed + braking torque" state, and the planetary gears (407, 416) rotate around the left half-shaft gear (402). While revolving clockwise without load, it also rotates counterclockwise, and the planetary gears (407, 416) drive the right half shaft gear (403) to rotate clockwise, transferring the power of the main power source to the output end / shaft (429); thirdly, the power regulating / speed regulating motor outputs clockwise torque, drives the left half shaft gear (402) to rotate clockwise, drives the planetary gears (407, 416) to rotate counterclockwise, and then drives the right half shaft gear (403) to rotate clockwise at an accelerated speed, thereby achieving the purpose of speed increase and speed regulation by superimposing the input power and regulating power confluence; fourthly, under emergency conditions, the power regulating / speed regulating motor outputs counterclockwise torque, drives the left half shaft gear (402) to rotate counterclockwise, drives the planetary gears (407, 416) to rotate clockwise, and then the negative torque (opposite to the clockwise direction of the driving load) drives the right half shaft gear (403) to rotate at a reduced speed, thereby achieving the purpose of speed reduction and emergency speed regulation by dividing the input power and regulating power.

[0064] In summary, according to actual needs, five modules / operating modes can be conveniently constructed for real-time system call and operation: ① soft start module ② hot engine / light load module ③ basic operation module ④ stepless speed increase operation module ⑤ speed reduction / emergency adjustment operation module.

[0067] On the one hand, the main power source drives the sun gear (502) of the left half shaft (509) to revolve, and transmits the power to the right half shaft circular surface planetary gear (517) through the left planetary gear (503) and the cylindrical gear pair (518, 519) and the right circular surface planetary gear (503, 517) to rotate, thereby converging the power of the main power source to the power output end / shaft; on the other hand, the rotor (531) of the power adjustment / speed regulation motor rotates to drive the left and right central planetary oblique shafts (505, 515) and their cylindrical gear pairs (518, 519) and the cylindrical gear pairs (518, 519) and the right circular surface planetary gears (503, 517), and the power adjustment power is converged to / divided out of the power output end / shaft, thereby achieving the purpose of stepless speed regulation.
