Abstract
Description
Technical Field
[0001] The invention relates to a motor, in particular to a discrete-speed flexible motor. Background Art
[0002] As energy conservation and emission reduction are no longer just of economic significance, but more importantly of importance in preventing global temperature rise, energy conservation and emission reduction are particularly important for the motor industry, which uses the largest amount of electric energy.
[0003] The number of poles of a traditional motor is the number of magnetic poles of the motor, such as 2-pole motors and 4-pole motors. The number of poles corresponds to the synchronous speed of the motor. The synchronous speed of a 2-pole motor is 3000r / min, the synchronous speed of a 4-pole motor is 1500r / min, the synchronous speed of a 6-pole motor is 1000r / min, the synchronous speed of an 8-pole motor is 750r / min, the synchronous speed of a 10-pole motor is 600r / min, and the synchronous speed of a 12-pole motor is 500r / min. Usually, for motors with different pole numbers of the same power, type, and energy efficiency requirements, the efficiency is ranked from top to bottom as 4-pole, 2-pole, 6-pole, 8-pole, 10-pole, 12-pole, etc., that is, the more poles a motor has, the lower its efficiency.
[0004] Therefore, traditional motors have the following application deficiencies: first, the more poles there are, the lower the energy efficiency; second, the more poles there are, the lower the power factor and the greater the useless power loss; third, they cannot provide the required speed over a wide range. For example, under 50Hz operating frequency conditions, a motor with a synchronous speed of 900r / min or a synchronous speed of 5000r / min and many other specific speeds is required. According to the speed relationship corresponding to the number of motor poles, it is impossible to flexibly provide motor speeds that meet different requirements.
[0005] The existing electronic control technologies such as frequency conversion technology applied to motors can solve the problem of different motor speeds, but the electronic control technology itself consumes energy, which is not conducive to energy conservation and emission reduction for long-term operation of equipment. The existing matching traditional motors have high gear transmission efficiency and can provide the speed required for various specific working conditions, but they cannot achieve flexible transmission and are difficult to handle during startup and load overload. At the same time, the selection and design of the equipped motors cannot be selected according to the rated working conditions. The selection of the super-power motor of the big horse pulling the small cart is only for the environmental resistance of the startup and overload conditions, resulting in high energy consumption and cannot meet the contemporary requirements for energy conservation and consumption reduction. The patent applications with patent application numbers CN2021103236139, CN2021103235598, CN2021103234928 and CN2021103235579 disclose four flexible motors and flexible starting methods. The flexible motors can be flexibly transmitted, can solve the starting and overload resistance conditions, can achieve reasonable selection requirements, and maintain high-efficiency operation under rated conditions, but do not have the speed required for various specific working conditions, which restricts many application needs for flexible motors when different output speeds are required. Summary of the invention
[0006] In view of the above technical problems, the present invention provides a dispersed-speed flexible motor, which has flexible transmission performance throughout the whole process. The dispersed-speed flexible motor can adaptively isolate the load during the startup process, so that it can be started with a light load, without the need to attach an additional startup control device, and can also adaptively adjust the transmission mode according to the change of the load during operation. At the same time, the dispersed-speed flexible motor can adjust the output speed of the dispersed-speed flexible motor by conveniently adjusting the transmission ratio of its built-in transmission according to the working conditions, and flexibly adapt to the speed application requirements of suitable deceleration or acceleration, because the speed parameters output by the dispersed-speed flexible motor are densely dispersed, breaking the limitation of the inherent output speed parameters of traditional motors, and can form a dense dispersed speed distribution, which can adapt to the needs of various speed application occasions, solve the phenomenon of a big horse pulling a small cart in motor selection, and achieve the purpose of energy saving and consumption reduction.

[0047] Example 1
[0048] Figure 1-Figure 8 as well as Figure 17-Figure 20It is an embodiment of a dispersed-speed flexible motor of the present invention.

[0050] Figure 19-20 It is another form of the continuously variable transmission 2. As can be seen in the figure, the continuously variable transmission 2 includes a transmission housing 201. The interior of the transmission housing 201 is provided with a transmission inner cavity 207. The transmission inner cavity 207 is provided with oil. One end of the transmission housing 201 is provided with an intermediate transmission shaft 1006. The intermediate transmission shaft 1006 passes through the transmission housing 201 and enters the transmission inner cavity 207. The intermediate transmission shaft 1006 is rotatably connected to the transmission housing 201. A transmission sun gear 204 is fixedly provided on the intermediate transmission shaft 1006 located in the transmission inner cavity 207. The transmission sun gear 204 is fixedly provided on the intermediate transmission shaft 1006. A transmission planetary gear assembly 205 is provided on the outer circumference of 4, and the transmission planetary gear assembly 205 is composed of a plurality of transmission planetary gears 203, which are rotatably fixed on the inner wall of the transmission housing 201, and the plurality of transmission planetary gears 203 are respectively meshed and connected with the transmission sun gear 204, and a transmission bucket wheel assembly 208 is fixedly provided on the outer side of the transmission planetary gear assembly 205, and the transmission bucket wheel assembly 208 is composed of a plurality of transmission bucket wheels 206, and the transmission bucket wheels 206 are fixedly connected with the transmission planetary gears 203; the motor rotor output shaft 3001 is fixedly connected with the transmission housing 201.
[0051] In this embodiment, a positioning protrusion 1011 is provided on the outer circumference of the reducer housing 1003, and a positioning groove 3003 is provided on the inner circumference of the mounting seat 3002, and the positioning protrusion 1011 is located in the positioning groove 3003. The number of reducer planetary gears 1001 is 3-6, and different numbers can be selected as needed to increase the required transmission torque. When a large power needs to be transmitted, multiple reducer planetary gears 1001 can be selected, and generally 3 or 4 are selected, which can basically meet most transmission requirements.
[0052] During operation, the motor body 3 drives the continuously variable transmission 2 to operate, and the continuously variable transmission 2 transmits power to the intermediate transmission shaft 1006, and then realizes various required transmission ratios through the meshing transmission of the planetary gear and the sun gear.
[0053] Due to the combination of the reducer 1 and the continuously variable transmission 2, the flexible starting and flexible operation of the continuously variable transmission 2 can be achieved. The continuously variable transmission 2 can improve the impact during power starting, especially the requirement for light load when the motor body 3 is started. That is to say, due to the existence of the continuously variable transmission 2, the load can be isolated when the motor body 3 is started, so that the motor body 3 can be easily started; during operation, due to the existence of the continuously variable transmission 2, it can adapt to changes in working conditions and adaptively adjust to a variable speed or constant speed operation state; during the entire starting and running process, light load starting with load isolation during motor starting is achieved, and overload fluctuations in the operation process are improved during operation to achieve adaptive adjustment. In addition, due to the existence of the continuously variable transmission 2, the vibration caused by load fluctuations during operation can be isolated by the continuously variable transmission 2, ensuring that the amplitude parameters of the motor's operation are not affected by the fluctuations of the load, and the amplitude parameters fluctuate little. The existence of the continuously variable transmission 2 ensures that the motor runs smoothly. The dispersed-speed flexible motor can filter mechanical load fluctuations, that is, it provides a damping force that can counteract load fluctuations, while starting the load vibration isolation effect, thereby increasing the service life of the dispersed-speed flexible motor.
[0054] Since the reducer of this invention is a planetary gear reducer, the axial size can be very small, and the axes of various transmission components can be concentric, which makes it easier to integrate with the continuously variable transmission and the motor to form an overall motor structure, allowing users to directly select motors with various output speeds when selecting a motor. This eliminates the trouble of users having to consider the selection of a reducer when selecting a traditional motor, changes the traditional way of thinking about motor selection, and provides a convenient means for selecting industrial power.
[0055] The motor body 3 of the scattered-speed flexible motor can also be removed and used as an intermediate transmission link to improve the transmission performance of the transmission system and meet the current requirements for energy saving and environmental protection. At the same time, the flexible transmission transmission further improves the life and reliability of the transmission system and reduces the operating cost because it includes a continuously variable transmission 2.
[0056] The dispersed-speed flexible motor has full-process flexible transmission performance, which solves the problem that traditional motors often approach or exceed their inherent characteristic boundaries during startup and operation. It can be selected normally according to actual working conditions. The dispersed-speed flexible motor can adaptively isolate the load during the startup process, so that it can start with a light load, without the need for additional startup control devices. During operation, the transmission mode can also be adaptively adjusted according to the change of load. At the same time, the dispersed-speed flexible motor can adjust the output speed of the dispersed-speed flexible motor by conveniently adjusting the transmission ratio of its built-in transmission according to the working conditions, and flexibly adapt to the speed application requirements of suitable deceleration or acceleration. Because the speed parameters output by the dispersed-speed flexible motor are densely dispersed, breaking the limitations of the inherent output speed parameters of traditional motors, a dense dispersed speed distribution can be formed, which can adapt to the needs of various speed applications, solve the phenomenon of a big horse pulling a small cart in motor selection, and achieve the purpose of energy saving and consumption reduction. The flexible transmission of the dispersed-speed flexible motor throughout the process improves the life of the motor and the stability of operation.
[0057] The scattered-speed flexible motor in this embodiment 1 adopts a 2-pole 3-level efficiency motor with a synchronous speed of 3000rpm as the motor body 3, and the reducer 1 reduces the speed to 600rpm. Due to the high efficiency of the gear transmission, the scattered-speed flexible motor with a speed of 600rpm has an efficiency value greater than that of a 10-pole motor with a synchronous speed of 600rpm with a secondary efficiency. At the same time, it can greatly improve the power factor and reduce reactive loss. After this embodiment is popularized to multi-pole motors with more than 10 poles, its energy-saving effect and reduction of reactive loss are more obvious.
[0058] The above motor body 3 is integrated with the reducer 1 through the continuously variable transmission 2. Since the continuously variable transmission 2 has the characteristics of flexible starting and resistance to load fluctuations and isolation of load impact during operation, the starting and operation performance of the motor body 3 is greatly improved. Compared with the selection of traditional motors, a small-power motor can be matched under the same application scenario. The overall efficiency of the dispersed-speed flexible motor after the integration of such a motor body 3, the continuously variable transmission 2 and the reducer 1 is greater than that of the traditional multi-pole motor with the same speed, especially compared with a multi-pole motor with more than 10 poles. The efficiency level of the dispersed-speed flexible motor is higher, and the energy-saving effect and reduction of reactive loss are more obvious. After calculation and experiments, the energy-saving effect and reduction of reactive loss can exceed 10%-20%.
