Description

Technical Field

[0001] The present invention relates to the technical field of motors, and particularly to a worm and gear planetary reduction motor. Background Art

[0002] Planetary reduction motors are widely used in industrial automation equipment, robot drive systems, aerospace precision instruments, etc. due to their high torque output, high-precision transmission, and compact design. When the internal drive components (such as planetary gear sets, bearings, etc.) operate at high speeds, tooth surface friction and heat accumulation will be significantly aggravated, resulting in accelerated wear, decreased transmission efficiency, and even equipment failures. Therefore, precise lubrication of the drive components has become the key to ensuring the performance and lifespan of planetary reduction motors. However, the existing lubrication solutions for planetary reduction motors have significant defects: Currently, the lubrication of planetary reduction motors mainly relies on manual periodic lubricating oil filling or traditional fixed-mode automatic lubrication devices. The manual filling method is limited by the operation cycle. When the motor runs at high speed and the lubrication demand surges, it is difficult to replenish the lubricating oil in a timely manner, which easily leads to problems such as gear wear and abnormal temperature rise, seriously affecting the equipment reliability. Traditional automatic lubrication devices lack the ability to dynamically respond to the rotational speed. Whether the motor is in a high-speed or low-speed operating condition, they supply oil at a fixed frequency or flow rate. This results in insufficient lubricating oil supply at high speeds and excessive oil supply at low speeds, not only wasting resources but also potentially polluting the working environment due to lubricating oil leakage, increasing the maintenance cost. The continuous oil supply under low-speed operating conditions will also cause the oil to stagnate on the gear surface due to poor lubricating oil fluidity and low heat dissipation efficiency, exacerbating the oxidation and deterioration of the oil fluid, and instead reducing the lubrication effect. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a worm and gear planetary reduction motor, which realizes automatic oil supply only when the motor runs at high speed and stops oil supply at low speed, thereby solving problems such as lagging response, high energy consumption, and large pollution of traditional lubrication methods, and significantly improving the transmission efficiency and service life of planetary reduction motors.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A worm and gear planetary reduction motor includes a motor main body, a control member, an actuator, and a liquid outlet member. An outer housing is provided on the motor main body. A trigger member connected to the output shaft of the motor main body is provided inside the outer housing. The trigger member includes a fixed housing, a centrifugal block, and a first spring. The centrifugal block is slidably installed inside the fixed housing and is reset by the first spring. The control member is provided on the outer housing and is connected to the trigger member to convert centrifugal force into mechanical motion. The actuator is provided on the outer housing and is connected to the control member to pump lubricating oil into the motor interior. A plurality of liquid outlet members are respectively installed at the positions of the drive components inside the motor main body, and the plurality of liquid outlet members are connected to the actuator through pipe fittings.

[0005] Preferably, the triggering member further includes a first connecting ring and a second connecting ring. The fixed shell is disposed inside the outer shell. Guide rods are symmetrically arranged between the first connecting ring and the second connecting ring. The first connecting ring is connected to the output shaft of the motor body. The second connecting ring is rotatably arranged inside the fixed shell. The symmetrical arrangement of the guide rods ensures the structural stability and movement balance. The connection of the first connecting ring to the output shaft of the motor body enables the triggering member to rotate synchronously with the motor output shaft. The rotatable arrangement of the second connecting ring inside the fixed shell not only ensures the flexible rotation of the second connecting ring inside the fixed shell but also provides a stable support structure for the movement of the centrifugal blocks. The centrifugal blocks can slide between the first connecting ring and the second connecting ring along the guide rods.

[0006] Preferably, two centrifugal blocks and two first springs are symmetrically provided. The two centrifugal blocks are respectively movably arranged on the two guide rods. The two first springs are respectively sleeved on the two guide rods. The two ends of the first spring are respectively connected to the connecting ring and the centrifugal block. The function of the first spring is to pull the centrifugal block back to its initial position after it slides due to centrifugal force, realizing the reset function of the centrifugal block and ensuring the stable operation of the triggering member at different rotational speeds.

[0007] Preferably, the control member includes a mounting shell. A positioning block is arranged inside the mounting shell. A moving rod is movably arranged on the positioning block. A triggering block is arranged at one end of the moving rod close to the triggering member. A second spring is sleeved on the moving rod. A moving block is arranged at the other end of the moving rod away from the triggering block. A link mechanism connected to the actuator is arranged on the moving block. There is a through hole on the outer shell and a connection port on the fixed shell. One end of the mounting shell with the triggering block is installed into the connection port. The other end of the mounting shell passes through the through hole and is outside the outer shell. A triggering block is arranged at one end of the moving rod close to the triggering member. The triggering block cooperates with the centrifugal block in the triggering member. When the centrifugal block slides, it will push the triggering block, thereby driving the moving rod to move. A second spring is sleeved on the moving rod. The function of the second spring is to provide a reset force after the moving rod moves, making it return to its initial position. A moving block is arranged at the other end of the moving rod away from the triggering block. A link mechanism connected to the actuator is arranged on the moving block. When the moving rod moves, it will drive the moving block and the link mechanism to move, converting the centrifugal force generated by the triggering member into mechanical motion and transmitting it to the actuator. A rubber sheet or a spring for buffering can be arranged on one side of the triggering block close to the first connecting ring to avoid a large impact on the first connecting ring when the triggering block resets.

[0008] Preferably, the linkage mechanism includes a hinge block, a connecting rod, and a rotating plate. One end of the connecting rod is connected to the hinge block, and the other end is rotatably connected to the rotating plate. The hinge block is connected to the moving block, and the rotating plate is connected to the actuator. One end of the connecting rod is connected to the hinge block, and the other end is rotatably connected to the rotating plate. The hinge block is connected to the moving block. When the moving block moves along with the moving rod, it will drive the hinge block to move. The hinge block drives the rotating plate to rotate through the connecting rod. The rotating plate is connected to the actuator, transmitting the rotational motion of the linkage mechanism to the actuator, thereby realizing the function of the control part converting centrifugal force into mechanical motion and transmitting it to the actuator.

[0009] Preferably, the actuator includes a driving gear, a transmission gear set, and a conveying member. The driving gear is connected to the rotating plate through a pin shaft. The driving gear is connected to the conveying member through the transmission gear set. There is a bevel gear set on the conveying member. The conveying member is in transmission connection with the transmission gear set through the bevel gear set. The driving gear is connected to the rotating plate through a pin shaft. The rotation of the rotating plate will drive the driving gear to rotate. The driving gear is in transmission connection with the bevel gear set on the conveying member through the transmission gear set. The transmission gear set plays a role in transmitting power and changing the rotational speed and torque. The bevel gear set can change the direction of power transmission, enabling the rotation of the driving gear to be effectively transmitted to the conveying member, thereby driving the conveying member to pump lubricating oil. The bevel gear set consists of two bevel gears when in use for power transmission. The transmission gear set consists of multiple meshing gears for power transmission (both the bevel gear set and the transmission gear set are prior arts when in use and will not be described in detail).

[0010] Preferably, the output member includes a fixing plate. There is a circular groove on the fixing plate. A rotating rod is rotatably provided on the fixing plate. The rotating rod is located in the circular groove. There is a rotating block at one end of the rotating rod inside the circular groove. The other end of the rotating rod passes through the fixing plate and is connected to the bevel gear set. A conveying pipe is provided along the circular groove inside the fixing plate. There is a roller on the rotating block that squeezes the conveying pipe. When the rotating block rotates, the roller will squeeze the conveying pipe, realizing the pumping of lubricating oil in this squeezing manner, and conveying the lubricating oil from the liquid inlet end of the conveying pipe to the liquid outlet end.

[0011] Preferably, there are multiple rollers. Multiple connection ends corresponding to the multiple rollers are evenly provided on the rotating block. The multiple rollers are rotatably arranged on the multiple connection ends. The liquid outlet end of the conveying pipe penetrates into the fixing plate from above and penetrates out from below the fixing plate.

[0012] Preferably, the liquid outlet end of the delivery pipe is connected to a pipe fitting through a pipe joint. The pipe fitting includes a main delivery pipe and a plurality of branch pipes. The main delivery pipe is communicated with the plurality of branch pipes through a pipe joint, and the ends of each branch pipe are respectively connected to a plurality of liquid outlet members. This connection method enables the lubricating oil transported from the delivery pipe to be distributed to each liquid outlet member through the main delivery pipe and the branch pipes, realizing the lubrication of a plurality of transmission components inside the motor. When installing and fixing the liquid outlet member, it can be installed and fixed in position through an elastic pipe clamp.

[0013] Preferably, the liquid outlet member includes a liquid outlet head, Spring III, a plugging block, and a connector. The liquid outlet head and the connector are both provided with liquid outlet channels. Spring III and the plugging block are both arranged in the liquid outlet channel of the liquid outlet head. Spring III abuts against the plugging block, and the plugging block can slidably plug the liquid outlet channel on the liquid outlet head. When there is no lubricating oil pressure, the plugging block can slidably plug the liquid outlet channel on the liquid outlet head under the action of Spring III to prevent the leakage of lubricating oil; when the lubricating oil pumped by the actuator generates sufficient pressure, the lubricating oil will push the plugging block to overcome the elastic force of Spring III and open the liquid outlet channel, enabling the lubricating oil to flow out from the liquid outlet head to lubricate the transmission components inside the motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention controls the delivery of lubricating oil through a trigger member, completely solving the low-efficiency problem of the traditional lubrication system. When the motor runs at high speed, the centrifugal mechanism automatically starts the actuator to accurately deliver lubricating oil to key parts such as the planetary gear set and the bevel gear set, avoiding the lag of manual filling and the deficiencies of traditional fixed oil supply, and eliminating the double hidden dangers of insufficient oil supply at high speed and oil retention at low speed.

[0022] Please refer to Figures 1-6 , a worm and worm gear planetary reduction motor, including a motor main body 1, and the motor main body 1 includes a housing 11; Brushless worm motor 13: Installed at the rear end of the motor main body 1 as a power source, fixedly connected to the housing 11 through a flange, and the worm at its end meshes with the worm gear in the first tooth shaft 14; Second tooth shaft 15: Rotatably arranged in the housing 11 through a bearing, and the second tooth shaft 15 is meshed and connected with the first tooth shaft 14; Internal gear ring 18: Arranged on the housing 11; Planet gears 17: There are three of them, and the three planet gears 17 are evenly distributed on the outer periphery of the second tooth shaft 15, and each planet gear 17 is simultaneously meshed and connected with the second tooth shaft 15 and the internal gear ring 18; Output shaft 19: Vertically penetrating the top of the motor main body 1, rotatably connected to the housing 11 through a bearing, and its lower end is connected to the planet gear 17 through a pin 16, and the planet gear 17 is rotatably arranged on the pin 16.

[0023] During use, the brushless worm motor 13 drives the first tooth shaft 14 to rotate, the first tooth shaft 14 drives the second tooth shaft 15 to rotate, the second tooth shaft 15 drives the three planet gears 17 to rotate, the three planet gears 17 rotate relative to the internal gear ring 18, and the planet gear 17 drives the output shaft 19 to rotate through the pin 16. Finally, low-speed and high-torque power is output by the output shaft 19. Among them, through the worm and worm gear transmission between the worm and the first tooth shaft 14, cross-axis power transmission is realized, with self-locking function and low-noise characteristics. The meshing structure of the three planet gears 17 and the internal gear ring 18 converts the rotational motion of the second tooth shaft 15 into the low-speed and high-torque output of the output shaft 19.

[0024] Please refer to Figures 7-14, a control member 3, an actuator 4, and a liquid outlet member 5 are further provided on the motor main body 1. A trigger member 2 connected to the output shaft 19 of the motor main body 1 is provided inside the outer housing 11. The trigger member 2 includes a fixed housing 21, a centrifugal block 26, and a first spring 25. The centrifugal block 26 is slidably installed inside the fixed housing 21 and reset by the first spring 25. The control member 3 is provided on the outer housing 11 and can be connected to the trigger member 2 to convert centrifugal force into mechanical motion. The actuator 4 is provided on the outer housing 11 and connected to the control member 3 to pump lubricating oil into the motor. A plurality of liquid outlet members 5 are respectively installed at the positions of the transmission components inside the motor main body 1. The plurality of liquid outlet members 5 are connected to the actuator 4 through pipes. A bottom plate is provided on the outer housing 11, and the actuator 4 is installed on the bottom plate. A protective box for covering and protecting the actuator 4 is provided on the bottom plate. When supplying oil to the delivery pipe 446, it is supplied with oil through an oil supply tank storing lubricating oil. The oil supply tank is provided on an external bracket and placed above the delivery pipe 446. The oil outlet of the oil supply tank faces the delivery pipe 446 and is connected to it, so that the lubricating oil continuously supplies liquid to the delivery pipe 446 under the action of its own gravity, ensuring that there is always lubricating liquid in the delivery pipe 446.

[0025] Meanwhile, an oil return pipe is connected above the oil supply tank. An oil return hole is provided below the outer housing 11. The oil return pipe is connected to the oil return hole on the outer housing 11. The oil return pipe is connected to an external oil return tank. The oil return tank and the oil supply tank are connected by an oil pump, so that the lubricating oil in the oil return tank can be continuously transported into the oil supply tank, thereby achieving the circulation of the lubricating oil. In this embodiment, the oil return hole is opened on the outer wall of the outer housing 11 where the second gear shaft 15 is located, so that there is a certain height or distance difference between the oil inlet and the oil return.

[0026] The trigger member 2 further includes a first connecting ring 22 and a connected second connecting ring 23. The fixed housing 21 is provided inside the outer housing 11, and the second connecting ring 23 can rotate relative to the fixed housing 21. Guide rods 24 facing the first connecting ring 22 are provided on the inner wall of the second connecting ring 23. In this embodiment, two guide rods 24 are provided and symmetrically arranged. In another embodiment, the number of guide rods 24 can also be three, four or more, and all the guide rods 24 are circumferentially distributed along the inner wall of the second connecting ring 23. The increase in the number is used to increase the contact frequency with the control member 3 to control the oil output.

[0027] The connecting ring 1-22 is connected to the output shaft 19 of the motor body 1, specifically by key connection. The connection between the connecting ring 1-22 and the output shaft 19 of the motor body 1 enables the trigger member 2 to rotate synchronously with the motor output shaft 19. The connecting ring 2-23 is rotatably arranged in the fixed housing 21. This design not only ensures that the connecting ring 2-23 can rotate flexibly in the fixed housing 21 but also provides a stable support structure for the movement of the centrifugal block 26. The centrifugal block 26 can slide between the connecting ring 1-22 and the connecting ring 2-23 along the guide rod 24. A pressing end 261 is provided on the centrifugal block 26 to facilitate the pressing of the trigger block 32 by the centrifugal block 26.

[0028] There are two symmetrically arranged centrifugal blocks 26 and two first springs 25. The two centrifugal blocks 26 are respectively movably arranged on the two guide rods 24, and the two first springs 25 are respectively sleeved on the two guide rods 24. A hole is provided on the centrifugal block 26, and the guide rod 24 passes through the hole on the centrifugal block 26 and is connected thereto in a matching manner. The two ends of the first spring 25 respectively abut against the inner wall of the connecting ring 2-23 and the centrifugal block 26. The function of the first spring 25 is to pull the centrifugal block 26 back to its initial position after it slides due to centrifugal force, realizing the reset function of the centrifugal block 26 and ensuring that the trigger member 2 can work stably at different rotational speeds.

[0029] The control member 3 includes an installation shell 31. A positioning block 34 is provided inside the installation shell 31. A moving rod 33 is movably provided on the positioning block 34. A trigger block 32 is provided at one end of the moving rod 33 close to the trigger member 2. A second spring 35 is sleeved on the moving rod 33. A moving block 36 is provided at the end of the moving rod 33 away from the trigger block 32. A link mechanism connected to the actuator 4 is provided on the moving block 36. A through hole 12 is provided on the outer housing 11. A connection port 211 is provided on the fixed shell 21. One end of the installation shell 31 with the trigger block 32 is installed into the connection port 211. The other end of the installation shell 31 passes through the through hole 12 and is outside the outer housing 11. The trigger block 32 can be abutted against the centrifugal block 26 in the trigger member 2. When the centrifugal block 26 slides radially away from the connection ring 22, it will push the trigger block 32, thereby driving the moving rod 33 to move. A second spring 35 is sleeved on the moving rod 33. The function of the second spring 35 is to provide a restoring force after the moving rod 33 moves, so that it returns to the initial position. A moving block 36 is provided at the end of the moving rod 33 away from the trigger block 32. A link mechanism connected to the actuator 4 is provided on the moving block 36. When the moving rod 33 moves, it will drive the moving block 36 and the link mechanism to move, converting the centrifugal force generated by the trigger member 2 into mechanical motion and transmitting it to the actuator 4. A rubber sheet or a spring for buffering can be provided on one side of the trigger block 32 close to the connection ring 22, which can avoid a large impact on the connection ring 22 when the trigger block 32 resets. It should be particularly noted that the rotation speed of the output shaft 19 when the centrifugal block 26 slides radially away from the connection ring 22 can be within a preset range, which is achieved by selecting a spring 25 with a corresponding stiffness. The curve formula of the rotation speed of the output shaft 19 and the stiffness of the spring 25 can be obtained through multiple tests. Furthermore, fuel supply can be achieved at high speed or within a preset rotation speed range. When at low speed or the preset rotation speed is not reached, the centrifugal block 26 does not slide radially and no fuel is supplied.

[0030] The link mechanism includes a hinge block 37, a connecting rod 38, and a rotating plate 39. One end of the connecting rod 38 is connected to the hinge block 37, and the other end is rotatably connected to the rotating plate 39. The hinge block 37 is connected to the moving block 36. The rotating plate 39 is connected to the actuator 4. One end of the connecting rod 38 is connected to the hinge block 37, and the other end is rotatably connected to the rotating plate 39. The hinge block 37 is connected to the moving block 36. When the moving block 36 moves along with the moving rod 33, it will drive the hinge block 37 to move. The hinge block 37 drives the rotating plate 39 to rotate through the connecting rod 38. The rotating plate 39 is connected to the actuator 4, transmitting the rotational motion of the link mechanism to the actuator 4, thereby realizing the function that the control member 3 converts the centrifugal force into mechanical motion and transmits it to the actuator 4.

[0031] The actuator 4 includes a driving gear 41, a transmission gear set 42, and a conveying member 44. The driving gear 41 is connected to the rotating plate 39 through a pin shaft. A bevel gear set 43 is provided on the conveying member 44. The conveying member 44 is drivingly connected to the transmission gear set 42 through the bevel gear set 43. The driving gear 41 is connected to the rotating plate 39 through a pin shaft. The rotation of the rotating plate 39 will drive the rotation of the driving gear 41. The driving gear 41 is drivingly connected to the bevel gear set 43 on the conveying member 44 through the transmission gear set 42. The transmission gear set 42 plays a role in transmitting power and changing the rotational speed and torque. The bevel gear set 43 can change the direction of power transmission, enabling the rotation of the driving gear 41 to be effectively transmitted to the conveying member 44, thereby driving the conveying member 44 to pump lubricating oil. The bevel gear set 43 consists of two bevel gears during use for power transmission. The transmission gear set 42 is composed of multiple meshing gears for power transmission. The transmission ratio is selected according to the oil supply frequency (both the bevel gear set 43 and the transmission gear set 42 are prior arts during use and will not be described in detail).

[0032] The output member includes a fixing plate 441. A circular groove 442 is provided on the fixing plate 441. A rotating rod 445 is rotatably provided on the fixing plate 441. The rotating rod 445 is located at an eccentric position in the circular groove 442. A rotating block 443 is provided at one end of the rotating rod 445 in the circular groove 442. The other end of the rotating rod 445 passes through the fixing plate 441 and is connected to the bevel gear set 43. A conveying pipe 446 is provided in the fixing plate 441 along the circular groove 442. One end of the conveying pipe 446 extends from the outer wall of the fixing plate 441 into the circular groove 442 and is in contact with the inner wall of the circular groove 442. The other end of the conveying pipe 446 extends out of the circular groove 442. A roller 444 for squeezing the conveying pipe 446 is provided on the rotating block 443. There are multiple rollers 444. Multiple connection ends corresponding to the multiple rollers 444 are evenly provided on the rotating block 443. The multiple rollers 444 are rotatably provided on the multiple connection ends. When the rotating block 443 rotates, the rollers 444 will squeeze the conveying pipe 446. Through this squeezing method, intermittent oil supply of lubricating oil is realized, and the lubricating oil is conveyed from the liquid inlet end of the conveying pipe 446 to the liquid outlet end. At the same time, since the centrifugal block 26 intermittently squeezes and pushes the trigger block 32, under the restoring force of the second spring 35, the trigger block 32 drives the rotating plate 39 to swing intermittently and reciprocally. Through the transmission gear set 42, the rotating block 443 is driven to rotate reciprocally. When the eccentrically arranged rotating rod 445 rotates reciprocally, taking Figure 13 as an example, when the roller 444 on the side close to the inlet of the conveying pipe 446 rotates counterclockwise, that is, rotates away from the pipe joint 447, the contact force with the conveying pipe 446 gradually decreases, facilitating the re-filling of the conveying pipe 446 with lubricating oil. When the roller 444 on the side close to the inlet of the conveying pipe 446 rotates clockwise, that is, gradually approaches the joint 447 and the squeezing force on the conveying pipe 446 increases, the other roller 444 gradually reduces the squeezing force on the conveying pipe 446, thereby realizing smooth oil supply.

[0033] The liquid outlet end of the delivery pipe 446 is connected to a pipe fitting through a pipe joint 447. The pipe fitting includes a main delivery pipe and multiple branch pipes. The main delivery pipe is connected to the multiple branch pipes through the pipe joint 447. The ends of each branch pipe are respectively connected to multiple liquid outlet members 5. This connection method enables the lubricating oil delivered from the delivery pipe 446 to be distributed to each liquid outlet member 5 through the main delivery pipe and the branch pipes, realizing the lubrication of multiple transmission components inside the motor. When the liquid outlet member 5 is installed and fixed, its position can be installed and fixed through an elastic pipe clamp. An oil inlet end 6 is provided on its outer housing 11. The pipe fitting is connected to the oil inlet end 6 to supply oil in the direction of the liquid outlet member 5 inside the motor body 1, thereby supplying oil for lubrication inside the motor body 1.

[0034] The liquid outlet member 5 includes a liquid outlet head 51, a spring III 53, a plugging block 54, and a connecting head 52. Liquid outlet channels are provided on both the liquid outlet head 51 and the connecting head 52. The spring III 53 and the plugging block 54 are both arranged in the liquid outlet channel of the liquid outlet head 51. The spring III 53 abuts against the plugging block 54. The plugging block 54 can slide to block the liquid outlet channel on the liquid outlet head 51. When there is no lubricating oil pressure, the plugging block 54 can slide to block the liquid outlet channel on the liquid outlet head 51 under the action of the spring III 53 to prevent lubricating oil leakage; when the lubricating oil pumped by the actuator 4 generates sufficient pressure, the lubricating oil will push the plugging block 54 to overcome the elastic force of the spring III 53 and open the liquid outlet channel, enabling the lubricating oil to flow out from the liquid outlet head 51 to lubricate the transmission components inside the motor. The liquid outlet member 5 functions as a one-way valve.

[0035] Among them, the main delivery pipe branches out a branch pipe that transports oil in the direction of the actuator 4 through the pipe joint 447. This branch pipe further branches out multiple branch pipes through the pipe joint 447. The ends of these multiple branch pipes are respectively connected to multiple liquid outlet members 5, and these liquid outlet members 5 are respectively located above the driving gear 41, the transmission gear set 42, and the bevel gear set 43. With such a setting, while supplying oil to other transmission components inside the motor body 1, it is also possible to accurately supply oil for lubrication to the driving gear 41, the transmission gear set 42, and the bevel gear set 43.

[0036] Considering that the path lengths from multiple lubrication points to the actuator 4 are different, resulting in differences in the lengths of each pipeline. If not controlled, the lubricating oil may be preferentially discharged from the pipelines that are closer to the actuator 4 and have less pipeline resistance during transportation, and cannot be evenly delivered to the remaining lubrication points. To solve this problem, when actually setting the branch pipelines, it is necessary to make targeted adjustments to the resistance of the branch pipelines. By using branch pipelines with different pipe diameters and setting throttling elements (such as throttle valves, damping sheets, etc.) inside the branch pipelines, according to the lengths of each pipeline and the actual required lubricating oil flow rate, the resistance value of the pipeline is accurately adjusted to make the resistance of each pipeline match the pipeline length, so as to ensure that the lubricating oil can be evenly transported to multiple lubrication points under the action of pressure, and ensure that each key transmission component can be fully lubricated.

[0037] When the rotational speed of the output shaft 19 of the motor body 1 is relatively low, the centrifugal block 26 approaches the center position of the motor output shaft 19 under the action of the first spring 25. The trigger block 32 is not squeezed, and the control member 3 and the actuator 4 are in the initial state. The plugging block 54 of the liquid outlet member 5 plugs the liquid outlet channel under the action of the third spring 53, and the lubricating oil does not flow. When the rotational speed of the motor output shaft 19 increases to a certain extent, the centrifugal block 26 slides outward along the guide rod 24 by overcoming the elastic force of the first spring 25 under the action of centrifugal force. During the rotation, its pressing end 261 pushes the trigger block 32, causing the moving rod 33 to move, compressing the second spring 35. The moving block 36 drives the connecting rod 38 to move through the hinge block 37, and the connecting rod 38 drives the rotating plate 39 to rotate, thereby causing the driving gear 41 to rotate. The driving gear 41 drives the rotating rod 445 and the rotating block 443 of the conveying member 44 to rotate through the transmission gear set 42 and the bevel gear set 43. The rotating block 443 drives the roller 444 to squeeze the conveying pipe 446, bringing out the lubricating oil from the conveying pipe 446, and transporting the lubricating oil to the branch pipelines in the direction of the actuator 4 and the branch pipes in the direction of multiple motor bodies 1 through the conveying pipe 446, and transporting it to the positions of each liquid outlet member 5. As the lubricating oil is transported in the direction of the liquid outlet member 5, under the action of the lubricating oil pressure, the plugging block 54 can overcome the elastic force of the third spring 53 and open the liquid outlet channel, and the lubricating oil flows out onto the transmission components inside the motor to achieve lubrication. When the motor speed decreases, the centrifugal block 26 resets under the action of the first spring 25, the control member 3 and the actuator 4 return to the initial state, and the liquid outlet member 5 stops discharging oil.

[0038] The excess lubricating oil in the outer housing 11 enters the return oil pipe through the return oil hole provided below, and finally flows into the return tank to achieve circulation.
