Description

Technical Field

[0001] The present invention relates to the technical field of gear reduction motors, and specifically to an energy-saving brushless DC planetary gear reduction motor. Background Art

[0002] A brushless DC planetary gear reduction motor is a planetary gear reducer driven by a brushless motor. The meshing and cooperation between gears achieve the effect of reducing speed and increasing rotational force. Using an energy-saving brushless DC motor for driving can make the overall operation of the motor more energy-efficient.

[0003] Prior Art 1 (a Chinese patent with publication number CN118669492A, published on September 20, 2024) is a low-speed planetary gear reduction motor, which includes a driving member, a housing, a sun gear, a ring gear, a planetary disc holder, and multiple planetary gear reduction motors. A lubricating oil supply mechanism is provided inside the planetary gear reduction motor, and a hooking mechanism is provided on the ring gear. The lubricating oil supply mechanism includes a pull rod, a transmission component, a piston, and a first elastic member. An oil storage tank is opened inside the planetary gear reduction motor, the piston is slidably arranged in the oil storage tank, and an oil discharge hole is opened on the planetary gear reduction motor. This application utilizes the lubricating oil supply mechanism and the hooking mechanism. When the planetary gear reduction motor drives the pull rod to move to the bottom of the housing, the hooking mechanism hooks the pull rod and drives the piston to move. The piston sucks the lubricating oil into the oil storage tank. When the planetary gear reduction motor moves past the hooking mechanism, the hooking mechanism releases the pull rod, and the first elastic member pushes the piston to move back to its original position. The piston slowly squeezes out the lubricating oil in the oil storage tank through the oil discharge hole to lubricate the gears, reducing the frictional loss between the gears; Prior Art 2 (a Chinese patent with publication number CN218940869U, published on April 28, 2023) is a planetary gear reduction motor, which includes a sun gear. A first connecting shaft is fixedly connected to the center of the sun gear. Three inner planetary gear reduction motors are evenly meshed with the outer gear ring of the sun gear. A first buffer gasket is slidably installed on one side of the sun gear, and an output gear disc is slidably installed on one side of the first buffer gasket. The outer sides of the three inner planetary gear reduction motors are meshed and connected with an outer planetary gear reduction motor. This application can evenly distribute the load to different planetary gear reduction motors through the structure of the inner planetary gear reduction motors and the outer planetary gear reduction motors, resulting in high transmission efficiency, large output torque, and effectively reducing the wear and stress of a single gear.

[0004] Although the current planetary gear reduction motors have certain energy-saving effects, generally, the speed reduction effect of the reduction motor is constant, that is, its speed reduction output effect is in a constant ratio. The speed reduction output effect of the reducer cannot be adjusted. If multi-stage speed reduction adjustment is required, the reduction motor needs to be replaced or different reducers need to be combined for use, reducing the functionality and usage flexibility of a single reduction motor. Summary of the Invention

[0064] The input shaft 4 is driven to rotate by the driving motor 2. The input shaft 4 drives the first gear 5 to rotate. The first gear 5 drives the second gear 6 to move through the meshing with the second gear 6, so that the second gear 6 drives the first mounting plate 9 to rotate through the first movable shaft 8, providing rotational power for the connecting seat 11 and the transmission shaft 10.

The fourth gear 15 is arranged outside the support shaft 13 and a meshing connection is formed therebetween. The second fixed gear ring 16 is arranged outside the fourth gear 15 and a meshing connection is formed therebetween, and the second fixed gear ring 16 is fixed inside the motor housing 1. The second movable shaft 17 is fixed on the left side of the fourth gear 15.

The transmission shaft 11 passes through the mounting shaft 19 and a nested connection is formed therebetween. A slider 32 is fixed at the right end of the transmission shaft 11. The transmission shaft 11 forms a left-right sliding structure with the connection seat 10 through the slider 32. A translation control mechanism is arranged outside the transmission shaft 11 to control the horizontal movement of the transmission shaft 11 and control the transmission of the first transmission mechanism and the second transmission mechanism. The first transmission mechanism includes a first clamping block 22, a first clamping groove 23 and a first movable groove 24. The first clamping block 22 is fixed on the left side of the transmission shaft 11. The first clamping groove 23 is opened inside the output shaft 3, and the first clamping grooves 23 are equally angularly distributed with the center of the transmission shaft 11 as the center, and a clamping connection is formed between the first clamping groove 23 and the first clamping block 22. The first movable groove 24 is arranged in a ring shape and is arranged on the left side of the first clamping groove 23, and the first clamping groove 23 and the first movable groove 24 are communicated with each other.

The surface of the pushing block 31 is designed with an inclined structure, and the pushing block 31 is fixed on the surface of the transmission shaft 11.

[0066] When the transmission shaft 11 directly drives the output shaft 3 to rotate, the first clamping block 22 and the first clamping groove 23 are connected, so that the transmission shaft 11 drives the output shaft 3 to rotate. At the same time, the transmission shaft 11 rotates within the support shaft 13 and the mounting shaft 19 without driving the support shaft 13 to rotate. When the secondary deceleration mechanism needs to be used, the transmission shaft 11 is controlled to move horizontally, so that the first clamping block 22 is disengaged from the first clamping groove 23, and the transmission shaft 11 does not drive the output shaft 3 to rotate.

[0068] When controlling the movement of the transmission shaft 11, the control board 36 can be controlled to move through the telescopic controller 37, so that the control board 36 moves to form an enclosed ring structure and squeezes the connecting rod 35, causing the connecting rod 35 to push the extrusion block 33 to move. The extrusion block 33 pushes the transmission shaft 11 to move, adjusting the transmission direction of the transmission shaft 11. At the same time, the first spring 21 is squeezed and moves. When the control board 36 moves outwards later, the first spring 21 can push the transmission shaft 11 to reset through the push plate 20.
