Description

Technical Field

[0001] The utility model belongs to the technical field of reduction motors, and in particular relates to a lubrication type reduction motor component. Background Art

[0002] A reduction motor is a device that reduces the output speed of a motor's high-speed rotation through a reduction device. It combines the functions of a motor and a reduction device to provide a lower output speed and a higher driving torque.

[0003] The bearings in the gear motor are key components that bear the load and ensure smooth rotation. The bearings are located at the input or output end of the motor and support the rotating part of the motor.

[0004] In the existing technology, when lubricating the bearings, the bearings installed on the output shaft are usually directly removed, and lubricating oil is applied to the bearings to lubricate them. However, when the operating frequency of the motor is too high and the bearings need to be lubricated frequently, it may not be convenient to directly lubricate the bearings installed on the outside of the shaft. Frequent disassembly and installation of the bearings may be subjected to inappropriate pressure or torque, which may cause the bearings to deform or be damaged, thereby reducing the durability of the bearings.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0009] Preferably, a handle is fixedly connected to the outer side wall of the movable plate, and a fitting groove is provided on the motor body.

[0010] By arranging the handle and the fitting groove, it is possible to facilitate the movable plate to drive the outer ring of the bearing to rotate.

[0011] Preferably, the top of the small oil tank is fixedly connected to an oil inlet pipe, and the top of the oil inlet pipe is threadedly connected to a first closing cover.

The top of the small oil tank 6 is fixedly connected with an oil drain pipe 7, which is located at the bottom center of the small oil tank 6. The oil drain pipe 7 is arranged in an inclined shape, and the end of the oil drain pipe 7 away from the small oil tank 6 is located between the inner ring and the outer ring of the bearing 5. The inner wall of the small oil tank 6 is fixedly connected with a sponge block 8, which is mainly composed of sponge material and has a certain elasticity. After the lubricating oil inside the small oil tank 6 penetrates the sponge block 8, the lubricating oil slowly flows into between the outer ring and the inner ring of the bearing 5 through the oil drain pipe 7, and the movable plate 9 drives the outer ring of the bearing 5 to rotate through the action of the annular plate 10, so that the lubricating oil is evenly distributed between the outer ring and the inner ring of the bearing 5, thereby lubricating the bearing 5 and reducing the friction of the bearing 5 during operation.

[0028] Reference Figure 2 A handle 11 is fixedly connected to the outer wall of the movable plate 9. Five handles 11 are provided. The five handles 11 are located on the outer ring of the movable plate 9 and are distributed in a circular array. A fitting groove 12 is opened on the motor body 1. The handle 11 and the fitting groove 12 facilitate the movable plate 9 to drive the outer ring of the bearing 5 to rotate.

[0029] Reference Figure 4 The top of the small oil tank 6 is fixedly connected with an oil inlet pipe 13, and the oil inlet pipe 13 is located on one side of the top of the small oil tank 6. The top of the oil inlet pipe 13 is threadedly connected with a first closing cover 14. The inner wall of the first closing cover 14 is adapted to the outer wall of the top of the oil inlet pipe 13. By using the oil inlet pipe 13 and the first closing cover 14 in coordination, lubricating oil can be added to the interior of the small oil tank 6.

[0030] Reference Figure 3 A guide groove 15 is provided on the inner side wall of the second set of plates 4, and an oil collecting groove 16 is provided on the second set of plates 4 through the guide groove 15. The oil collecting groove 16 is an arc-shaped groove. The lubricating oil overflowing from the side of the bearing 5 close to the second set of plates 4 flows into the oil collecting groove 16 through the guide groove 15. The oil collecting groove 16 prevents the lubricating oil from dripping at will.

[0031] Reference Figure 3The second set of plates 4 is fixedly connected to a drain pipe 17 through an oil collecting tank 16. The bottom of the drain pipe 17 is rotatably connected to a second closing cover 18. The bottom outer wall of the drain pipe 17 is matched with the inner wall of the second closing cover 18. The lubricating oil inside the oil collecting tank 16 is discharged into a suitable container through the drain pipe 17 and the second closing cover 18.

[0032] Reference Figure 2-3 A first rotating groove 19 is provided on the first set of plates 3, and a second rotating groove 20 is provided on the second set of plates 4. The first rotating groove 19 and the second rotating groove 20 are symmetrically distributed with the central axis of the bearing 5 as the center. The first rotating groove 19 and the second rotating groove 20 are respectively adapted to the two annular plates 10. The movable plate 9 is connected to the second set of plates 4 through one of the annular plates 10, and is connected to the first set of plates 3 through the other annular plate 10. The first rotating groove 19 and the second rotating groove 20 facilitate the rotation adjustment of the two annular plates 10.

[0033] Working principle: First, the lubricating oil is added to the interior of the small oil tank 6 through the coordinated use of the oil inlet pipe 13 and the first closing cover 14. The lubricating oil slowly penetrates the sponge block 8, so that the lubricating oil slowly flows into the interior of the oil drain pipe 7. The oil drain pipe 7 transfers the lubricating oil and discharges it between the inner and outer rings of the bearing 5. The handle 11 and the fitting groove 12 drive the movable plate 9 to rotate, so that the outer ring of the bearing 5 rotates accordingly, ensuring that the lubricating oil can be evenly distributed inside the bearing 5. The annular plate 10, the first rotating groove 19 and the second rotating groove 20 increase the rotation stability of the movable plate 9. When lubricating the bearing 5, part of the excess oil flows through the guide groove 15 to the interior of the oil collecting groove 16. The oil collecting groove 16 collects part of the lubricating oil, and then the excess lubricating oil is collected and stored through the coordinated use of the drain pipe 17 and the second closing cover 18, thereby avoiding the lubricating oil from being discharged at will, and further avoiding pollution to the soil and water.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
