Description

Technical Field

[0001] This invention belongs to the field of electric motor technology, specifically a high-speed response motor structure with controllable inertia. Background Technology

[0002] High-speed response motors are widely used in precision servo control, automated equipment, high-precision transmission, and short-time rapid start-stop applications. These motors have stringent requirements for dynamic response speed, start-stop tracking accuracy, and rotor rotational inertia matching. To ensure high-speed dynamic response performance, the rotor magnetic circuit flux is typically required to be in a state of excellent conduction. The industry practice is to use silicon steel sheets with excellent magnetic permeability to form the mounting and connection base of the rotor permanent magnet. Due to the material properties of silicon steel sheets and the constraints of magnetic circuit design, in order to ensure overall magnetic permeability, reduce magnetic reluctance loss, and optimize flux distribution, it is not possible to add additional counterweights, weight reduction, or inertia adjustment structures to the rotor silicon steel sheet structure. At the same time, the internal assembly space of the motor is compact and the structural redundancy is low, making it difficult to integrate inertia adjustment components in the rotor body area.

[0003] To compensate for the insufficient rotational inertia caused by the inability to configure a counterweight structure on the rotor itself, existing conventional technologies usually involve increasing the axial length of the motor housing, reserving additional installation space inside the housing, and configuring an inertia disk that is coaxially fixed to the motor main shaft. The overall rotational inertia of the rotor system is improved by relying on the inertia disk to rotate synchronously with the main shaft.

[0004] However, existing traditional structures have significant technical limitations in practical applications: 1. The rotational inertia provided by the inertia disk is positively correlated with its own weight, outer diameter, and operating speed. However, due to the constraints of the radial structural dimensions of the motor housing, the outer diameter of the inertia disk cannot be increased. At the same time, the inertia disk is rigidly connected to the motor spindle, and its maximum operating speed is limited by the maximum rated speed of the motor rotor itself. It is impossible to independently break through the rotor speed limit to enhance the inertia matching. As a result, the traditional structure is difficult to efficiently and reasonably configure and increase the rotational inertia required by the rotor system within the limited assembly space of the motor. The upper limit of inertia configuration is low, the space utilization rate is poor, and it cannot meet the needs of large inertia working conditions.

[0005] 2. In different practical application scenarios, some operating conditions require the motor to have a large moment of inertia to ensure smooth start-stop and strong load disturbance resistance. Other operating conditions require the motor to maintain a low moment of inertia to achieve rapid start-stop and high-frequency dynamic response. The rotor system of traditional motor structure has a fixed value of inertia at the factory, and it is not possible to switch and adjust between high inertia and low inertia on the same motor. Users can only rely on purchasing motors of different models and inertia specifications for adaptation.

[0006] 3. During on-site equipment commissioning, changes in operating conditions, and process adjustments, it is often necessary to repeatedly disassemble and replace motors of different specifications. The assembly and commissioning workload is large, the adaptability is poor, the equipment has low versatility, and it is impossible to directly switch and control the inertia parameters on demand on the original motor body structure. There are obvious shortcomings in ease of use and adaptability to operating conditions. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention addresses the technical problem by using a first inertia ring as an inertia disk to increase the rotational inertia of the main shaft. By rotating a pivot pin to change the position of the balls, the balls switch between rolling grooves and locking grooves. This allows the first inertia ring to selectively connect to the main shaft, enabling the motor to switch between two inertia requirements without repeated disassembly and reassembly of motors with different needs. This facilitates debugging during equipment installation and use. Pulling and rotating the pin controls the torsional motion of the pivot pin, switching between different inertia states. A hexagonal prism and hexagonal hole lock the pivot pin in place. In actual use, only the tail cover needs to be removed to operate the pin, making operation convenient and efficient, and further facilitating motor debugging. By incorporating gears and a second inertia ring, the first inertia ring rotates at high speed driven by the main shaft, while the gears distribute the rotational inertia... The meshing transmission between the fixed ring and the gear ring on the second inertia ring further drives the second inertia ring to rotate at high speed, thereby further increasing the rotational inertia. By forming a planetary gear set with the first inertia ring, the fixed ring, and the second inertia ring, the rotation of the first inertia ring drives the second inertia ring to rotate at an even faster speed, so that the rotational speed of the second inertia ring exceeds the maximum speed limit of the main shaft, thus further enhancing the rotational inertia. This solution changes the structure to the way it is set up in the main shaft, and sets up a planetary gear set with the fixed ring, gear, and second inertia ring for acceleration. This allows the second inertia ring with a limited diameter to obtain the equivalent rotational inertia of a larger diameter inertia disk within the small and limited space of the motor. This eliminates the need to change the main structure of the motor, saving the cost of redesigning and manufacturing a new motor configuration, and effectively controlling the axial dimension of the motor, avoiding unnecessary length increases in the motor after adding the inertia disk, which would affect assembly and use.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an inertial controllable high-speed response motor structure, comprising: The housing has an end cap fixedly installed at its end. A tail cover is fixedly connected to the end of the end cap away from the housing. A main shaft is rotatably installed at the center between the end of the housing away from the end cap and the end cap. A set of stator coils is fixedly installed on the inner wall of the housing. A silicon steel sheet is fixedly installed on the main shaft at the corresponding position of the stator coil. Multiple magnets are evenly distributed inside the silicon steel sheet. A controllable inertial component is installed on the main shaft between the silicon steel sheet and the end cap. The controllable inertial component includes a first inertial ring, which is sleeved on the outside of the main shaft. A fixed ring surrounding the outside of the main shaft is fixedly disposed on the end face of the end cap near the first inertial ring. First needle roller bearings are respectively disposed on the end faces of the two sides of the main shaft. The two first needle roller bearings respectively roll in contact with the end faces of the silicon steel sheet and the fixed ring. The first inertial ring is optionally connected to the main shaft drive.

[0009] Furthermore, a first main bearing sleeved on the outside of the main shaft is provided at the end of the outer casing away from the end cover, a second main bearing sleeved on the outside of the main shaft is provided between the end cover and the first inertia ring, and an oil seal sleeved on the outside of the main shaft is provided at the end of the outer casing.

[0010] Furthermore, multiple ball grooves are formed on the axial surface of the main shaft at the position corresponding to the first inertia ring. The length of each ball groove is parallel to the axis of the main shaft in the opposite direction. A ball is rolled in each ball groove. An annular rolling groove is formed on the inner wall of the first inertia ring near the fixed ring. The rolling groove is used to accommodate the rolling of the ball. Multiple locking grooves are evenly distributed on the inner wall of the first inertia ring away from the fixed ring. The locking grooves are used to lock the rolling of the ball. The groove shape of both the locking groove and the rolling groove matches the ball contour.

[0011] Furthermore, the end of the ball near the end cap is hollow, and each of the locking grooves is connected to the hollow part of the ball. A rotating pin is rotatably connected inside the hollow part of the ball, and a spiral groove is provided on the outer wall of the rotating pin at the corresponding position of each ball. The rolling range of each ball is limited by the spiral groove.

[0012] Furthermore, a pin is provided inside the end of the ball in the air, a spline pin is provided at the end of the pin near the rotating pin, and a spline groove is provided at the end of the rotating pin near the pin to slide with the spline pin.

[0013] Furthermore, the hollow end of the main shaft is threadedly connected to a shaft cover, the shaft cover has a hexagonal hole in the center, the ball is provided with a hexagonal prism matching the shape of the hexagonal hole, a spring is provided between the ball and the shaft cover and surrounds the outside of the pin, and an electric control panel is fixedly connected to one end of the pin that extends out of the hexagonal hole.

[0014] Furthermore, a second inertial ring is provided inside the outer casing between the silicon steel sheet and the fixed ring. The second inertial ring is coaxially arranged with the first inertial ring. A second needle roller bearing is provided at both ends of the second inertial ring. The two second needle roller bearings roll in contact with the end faces of the silicon steel sheet and the fixed ring, respectively. The second inertial ring and the first inertial ring are connected by transmission.

[0015] Furthermore, multiple gears are evenly distributed and rotatably arranged on the outer ring of the first inertia ring, and an external gear ring is provided at one end of the fixed ring near the first inertia ring. An internal gear ring is provided on the inner wall of the second inertia ring at the corresponding position of the fixed ring. Each of the gears simultaneously meshes and drives with the external gear ring of the fixed ring and the internal gear ring of the second inertia ring.

[0016] Furthermore, each gear has a shaft end at the rotatable connection point with the first inertia ring, and gear bearings are provided on both end faces of the first inertia ring that are rotatably connected to each gear. Each gear bearing is sleeved on the shaft end of the corresponding gear, and a retaining ring is snapped onto the shaft end of each gear to abut against the corresponding gear bearing.

[0017] In summary, compared with the prior art, the beneficial effects of the present invention are as follows: (1) By setting the first inertia ring as an inertia disk to increase the rotational inertia of the main shaft, and by turning the rotating pin to change the position of the ball, the ball can switch between the rolling groove and the locking groove, so that the first inertia ring can be optionally connected to the main shaft power, so that the motor can switch between two inertia requirements without repeatedly disassembling and assembling motors with different requirements, which is convenient for debugging during equipment installation and use.

[0018] (2) This solution can control the torsional action of the rotating pin by pulling and turning the pin to achieve the switching of different inertial states. The state of the rotating pin is locked by using the hexagonal prism and hexagonal hole. In actual use, the pin can be operated by simply removing the tail cover. The operation is convenient and efficient, and it is more convenient to debug the motor.

[0019] (3) By setting up gears and a second inertia ring, the first inertia ring is driven by the main shaft to rotate at high speed. At the same time, the gears are driven to rotate at high speed by meshing with the fixed ring and the gear ring on the second inertia ring respectively, so as to further increase the rotational inertia. The first inertia ring, the fixed ring and the second inertia ring form a planetary gear set, so that the first inertia ring rotates while driving the second inertia ring to rotate at a faster speed, so that the rotational speed of the second inertia ring exceeds the limit of the maximum speed of the main shaft, thus further enhancing the rotational inertia.

[0020] (4) The structure of this solution is changed to the setting method in the main shaft, and the setting of the fixed ring, gear and second inertia ring to form a planetary gear set for acceleration. This can make the second inertia ring with a limited diameter obtain the rotational inertia of an inertia disk with a larger diameter in the small and limited space of the motor, so that the main structure of the motor does not need to be changed, saving the cost of redesigning and manufacturing a new configuration motor, and effectively controlling the axial dimension of the motor, avoiding unnecessary length increase of the motor after adding the inertia disk, which affects assembly and use.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] like Figure 1-10As shown, an inertial controllable high-speed response motor structure includes a housing 10, an end cap 11 fixedly connected to one end of the housing 10, a main shaft 13 rotatably mounted at the center of the housing 10 and the end cap 11, a first main bearing 17 and a second main bearing 18 respectively sleeved on the outside of the main shaft 13 at the rotatable connection points of the housing 10 and the end cap 11, an oil seal 19 sleeved on the outside of the main shaft 13 is provided in the end face of the housing 10 away from the end cap 11, the inner ring of the oil seal 19 is tightly fitted with the surface of the main shaft 13, a plurality of stator coils 16 are fixedly mounted on the inner wall of the housing 10, and silicon steel sheets 14 are fixedly connected on the main shaft 13 at the corresponding positions of the stator coils 16, a plurality of magnets 15 are evenly embedded in the silicon steel sheets 14 in a circumferential direction.

[0034] like Figure 1-10 As shown, a first inertia ring 20 is provided between the silicon steel sheet 14 and the end cap 11, surrounding the outside of the main shaft 13. The main shaft 13 is hollow near the center of the first inertia ring 20. A rotating pin 28 is rotatably installed inside the hollow part of the main shaft 13. Three ball bearing grooves 41 are evenly distributed in the circumferential direction on the surface of the main shaft 13 at the corresponding positions of the first inertia ring 20. The length direction of each ball bearing groove 41 is parallel to the axial direction of the main shaft 13. The outer wall of the rotating pin 28 is located on each ball bearing groove 41. A spiral groove 29 is provided at the corresponding position, and a ball 30 is rolled in each ball groove 41. Each ball 30 rolls and fits with the corresponding spiral groove 29. A rolling groove 32 that can accommodate the rolling of the ball 30 is provided on the inner wall of the first inertia ring 20 near the end cover 11. A plurality of locking grooves 31 that communicate with the rolling grooves 32 are evenly distributed on the inner wall of the first inertia ring 20 near the silicon steel sheet 14. The groove shape of each locking groove 31 and the rolling groove 32 matches the contour of the ball 30.

[0035] By setting the first inertia ring 20 as an inertia disk, during the high-speed rotation of the main shaft 13, the balls 30 are engaged in the locking groove 31, thereby transmitting power between the first inertia ring 20 and the main shaft 13. This causes the first inertia ring 20 to rotate at high speed along with the main shaft 13, increasing the rotational inertia of the main shaft 13. When the motor is not used in a scenario requiring high inertia, by turning the rotating pin 28, the spiral groove 29 drives the balls 30 to slide along the ball straight groove 41, allowing the balls 30 to... When the ball 30 slides from the locking groove 31 into the rolling groove 32, it is no longer locked by the locking groove 31 and can roll freely in the rolling groove 32. At this time, the first inertia ring 20 is no longer directly connected to the main shaft 13. The rotation of the main shaft 13 will not drive the first inertia ring 20 to rotate. Therefore, the first inertia ring 20 will not increase the rotational inertia of the main shaft 13. This allows the motor to switch between two needs without repeatedly disassembling and assembling the motor, making it easier to debug during equipment installation and use.

[0036] When the motor outputs power and torque, the main area of ​​the spindle 13 that bears the torque is the area where the silicon steel sheet 14 is located and the power output end of the spindle 13. The hollow part of the spindle 13 is located at the end of the spindle 13, which will not affect the overall structural strength and torsional strength of the spindle 13 too much, ensuring that the spindle 13 can stably output power and torque.

[0037] like Figure 1-10 As shown, a pin 33 is provided inside the air end of the ball 30. A spline pin 35 is provided at the end of the pin 33 near the rotating pin 28. A spline groove 36 that slides with the spline pin 35 is provided at the end of the rotating pin 28 near the pin 33. A shaft cover 38 is threadedly connected to the hollow end of the main shaft 13. A hexagonal hole 39 is provided in the center of the shaft cover 38. A hexagonal prism 34 that matches the shape of the hexagonal hole 39 is provided on the ball 30. A spring 37 is provided between the ball 30 and the shaft cover 38 and surrounds the outside of the pin 33. An electric control disk 40 is fixedly connected to the end of the pin 33 that extends out of the hexagonal hole 39. A tail cover 12 that covers the electric control disk 40 is fixedly connected to the end of the end cover 11 that is away from the outer shell 10.

[0038] By setting the pin 33, the rotation of the rotating pin 28 can be controlled by turning the pin 33 through the engagement of the spline pin 35 and the spline groove 36, thereby switching the connection state between the ball 30 and the first inertia ring 20. By setting the hexagonal prism 34 and the hexagonal hole 39, the rotation of the pin 33 can be locked by the engagement of the hexagonal prism 34 and the hexagonal hole 39 when the motor is running normally, thereby locking the rotation state of the rotating pin 28. This prevents the rotating pin 28 from spontaneously twisting during the high-speed rotation of the spindle 13, which would cause a change in the state of the ball 30 and a change in its inertia.

[0039] Meanwhile, the electric control panel 40 can be used to process and control the motion state of the motor. When it is necessary to switch the inertial state, the tail cover 12 can be removed and the ends of the electric control panel 40 and the pin 33 can be pulled and twisted to easily switch the connection state of the first inertial ring 20. The operation is simple and stable.

[0040] The structure of the rotating pin 28 and the latch 33 can maintain stable and accurate switching action without occupying valuable space inside the motor, effectively controlling the axial dimension of the motor, so that the motor size can be adapted to more assembly and use scenarios.

[0041] like Figure 1-10As shown, a retaining ring 21 is fixed on the end face of the end cap 11 near the silicon steel sheet 14, surrounding the outside of the main shaft 13. The retaining ring 21 is used to cooperate with the tail cover 12 to fix the second main bearing 18. First needle roller bearings 26 are respectively provided on the two end faces of the first inertia ring 20, surrounding the outside of the main shaft 13. The two first needle roller bearings 26 respectively roll in contact with the end faces of the silicon steel sheet 14 and the retaining ring 21. A second inertia ring 23 is provided between the silicon steel sheet 14 and the retaining ring 21, surrounding the outside of the first inertia ring 20. Multiple gears 22 are evenly distributed and rotatably arranged on the outer ring of the first inertia ring 20. The retaining ring 21... An external gear ring is provided at one end near the first inertia ring 20, and an internal gear ring is provided on the inner wall of the second inertia ring 23 at the corresponding position of the fixed ring 21. Each gear 22 is simultaneously meshed and connected to the external gear ring of the fixed ring 21 and the internal gear ring of the second inertia ring 23. The part of each gear 22 that is rotatably connected to the first inertia ring 20 is provided as a shaft end. Gear bearings 24 are provided on both end faces of the first inertia ring 20 that are rotatably connected to each gear 22. Each gear bearing 24 is sleeved on the shaft end of the corresponding gear 22, and a retaining ring 25 that abuts against the corresponding gear bearing 24 is snapped onto the shaft end of each gear 22.

[0042] By setting gear 22 and second inertia ring 23, the first inertia ring 20 is driven by the main shaft 13 to rotate at high speed. At the same time, the gear 22 is driven by the meshing transmission with the fixed ring 21 and the gear ring on the second inertia ring 23, which further drives the second inertia ring 23 to rotate at high speed, thereby increasing the rotational inertia. The first inertia ring 20, fixed ring 21 and second inertia ring 23 form a planetary gear set, which drives the second inertia ring 23 to rotate at an even faster speed while the first inertia ring 20 rotates. This causes the rotational speed of the second inertia ring 23 to exceed the maximum speed limit of the main shaft 13, thereby further increasing the rotational inertia.

[0043] This configuration allows the second inertia ring 23, with a finite diameter, to achieve rotational inertia equivalent to that of an inertia disk with a larger diameter within the limited space of the motor. This eliminates the need to change the main structure of the motor, saving the cost of redesigning and manufacturing a new motor configuration. It also effectively controls the axial dimension of the motor, avoiding unnecessary length increases that would affect assembly and use after adding the inertia disk.

[0044] In this embodiment, initially, the operator installs the main body of the motor on the equipment that needs to be powered. Then, according to the inertia requirements of the power input, the connection state of the first inertia ring 20 is changed. Taking the switching from low inertia to high inertia as an example, the operator releases the fixation of the control panel 40 and then pulls the end of the pin 33 to make the hexagonal prism 34 disengage from the range of the hexagonal hole 39 and compress the spring 37. The spline pin 35 slides in the spline groove 36 but does not completely disengage from the spline groove 36. Then, the operator rotates the pin 33 counterclockwise, and the engagement between the spline pin 35 and the spline groove 36 drives the rotating pin 28 to rotate counterclockwise at the same time.

[0045] At the same time, the rotation of the rotating pin 28 forces the balls 30 to roll along the spiral groove 29. The balls 30 then roll away from the end cover 11 in the ball straight groove 41 until each ball 30 rolls from the rolling groove 32 into the corresponding locking groove 31. The balls 30 then power the main shaft 13 and the first inertia ring 20. The rotational power of the main shaft 13 can be directly transmitted to the first inertia ring 20. By controlling the pitch setting pin 33 of the spiral groove 29 to rotate 60°, the balls 30 can complete the state switching.

[0046] After the switch is completed, the operator can directly release the pin 33, and the spring 37 will release and push the pin 33 to reset. Since the pin 33 has a twist angle of 60°, the shape of the hexagonal prism 34 still accurately corresponds to the shape of the hexagonal hole 39. The hexagonal prism 34 re-enters the hexagonal hole 39 and locks with it. The control panel 40 and the tail cover 12 are then re-fixed, and the adjustment and switching of the connection state of the first inertia ring 20 can be completed. There is no need to replace the entire motor or disassemble the main structure of the motor, so the adjustment and switching can be carried out conveniently, improving the efficiency of equipment debugging.

[0047] When the motor is operating in a low inertia state, the main shaft 13 rotates at high speed. The balls 30 are restricted to roll in the locking groove 31 by the combined action of the spiral groove 29 and the ball straight groove 41. The first inertia ring 20 will not rotate with the main shaft 13 at high speed, so the inertia of the motor rotor is small.

[0048] When the motor is operating under high inertia, the first inertia ring 20 rotates at high speed along with the main shaft 13, which increases the rotational inertia of the main shaft 13. At the same time, the first inertia ring 20 drives the gear 22 to revolve. The outer gear ring of the fixed ring 21 meshes with the gear 22, causing the gear 22 to rotate on its own axis while revolving. The gear 22 then drives the second inertia ring 23 to rotate. Driven by the gear 22, the second inertia ring 23's rotation speed further exceeds that of the main shaft 13 and the first inertia ring 20, thus giving the second inertia ring 23 itself greater inertia. The inertia of the second inertia ring 23 is equivalent to the inertia obtained by an inertia disk with a diameter much larger than the diameter of the second inertia ring 23 itself.
