[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] For example, a reducer with Chinese patent publication number CN211924850U includes a motor, a reducer box and a bearing. The reducer box has a mounting opening, and the inner wall of the mounting opening has a limiting portion. The motor has a front end cover, and the front end cover has a through-opening. The front end cover is fixed to the reducer box and the through-opening is opposite to and connected to the mounting opening. The bearing is arranged in the mounting opening and the through-opening. The inner diameter of the through-opening is the same as the inner diameter of the mounting opening and matches the outer diameter of the bearing.

[0004] The reducer in the above patent can only achieve the purpose of improving transmission accuracy when in use. However, when the existing reducer is in use, the gears outside the reducer lack intermittent lubrication components, so the gears outside the reducer cannot perform the intermittent lubrication function. Therefore, the gears outside the reducer need to be frequently filled with lubricating oil. Therefore, a device is needed to improve the above problem. Utility Model Content

[0021] The collecting device 2 includes a protective cavity 13, a first gear 14 and a circulating pump 15. The first gear 14 is rotatably installed inside the protective cavity 13. The circulating pump 15 is fixedly installed on both sides of the protective cavity 13. Connecting pipes are fixedly installed through the top and bottom ends of the circulating pump 15, and the connecting pipes are respectively connected to the protective cavity 13 and the central cavity 10, so that when the circulating pump 15 is started, the lubricating oil inside the protective cavity 13 can be drawn into the central cavity 10.

[0022] The supporting device 3 includes a second gear 16 and a reducer 17. The second gear 16 is fixedly mounted on the side end of the reducer 17 and is connected to the reduction gear inside the reducer 17 via the second gear 16, so that the second gear 16 can transmit power.

[0023] The protective cavity 13 is fixedly mounted on the side end of the reducer 17 close to the second gear 16 , and the central cavity 10 is fixedly mounted on the top end of the protective cavity 13 , which can support the central cavity 10 to transport lubricating oil.

[0024] The cam 5 is vertically aligned with the bottom of the side end of the cross-shaped top plate 12 close to the driving motor 4 , and when the cam 5 rotates, it can contact the bottom ends of both sides of the cross-shaped top plate 12 .

[0025] The dripping cavity 8 is located at the inner top of the protection cavity 13 , and the dripping cavity 8 is vertically aligned with the first gear 14 and the second gear 16 , so that the lubricating oil can be dripped onto the top of the first gear 14 and the second gear 16 .

[0026] Working principle: When in use, the second gear 16 is located inside the protective cavity 13, and the second gear 16 is meshed with the first gear 14, so that the power transmitted inside the reducer 17 can drive the first gear 14 to rotate. At the same time, the first gear 14 is connected to the shaft rod outside, so that the power can be transmitted. At the same time, the drive motor 4 can be started to drive the cam 5 to rotate. When the raised part of the cam 5 rotates to the bottom end of the cross-shaped top plate 12, the cross-shaped top plate 12 can be driven to move upward. When the cross-shaped top plate 12 moves upward, the sealing rubber plug can be driven by the sliding rod 6. 7 moves upward at the same time, so that the sealing plug 7 can be removed from the inside of the delivery pipe 9. At the same time, the lubricating oil is stored in the interior of the central cavity 10, and the central cavity 10 is interconnected with the delivery pipe 9, so that the lubricating oil in the central cavity 10 can flow to the inside of the dripping cavity 8 through the delivery pipe 9. The bottom end of the dripping cavity 8 is provided with a dripping hole, and the dripping cavity 8 is located above the first gear 14 and the second gear 16, so that the lubricating oil can be dripped onto the surface of the first gear 14 and the second gear 16, completing the surface lubrication of the first gear 14 and the second gear 16. At the same time, the circulation pump 15 can be started, and the connecting pipes at the upper and lower ends of the circulation pump 15 are respectively connected to the bottom end of the protective cavity 13 and the top end of the concentrated cavity 10, so that the circulation pump 15 can return the lubricating oil accumulated at the bottom end of the protective cavity 13 to the inside of the concentrated cavity 10 again, and the lubricating oil can be used repeatedly. Afterwards, when the raised part of the cam 5 rotates and passes the bottom end of the cross-shaped top plate 12, the elasticity of the return spring 11 will squeeze the sealing plug 7 to move downward to the inside of the delivery pipe 9 again, so that the delivery pipe 9 can be closed to prevent the concentrated cavity 10 from leaking. 0 excessive lubricating oil inside flows into the inside of the dripping cavity 8. When the device is in use, the cam 5 intermittently passes through the bottom end of the cross-shaped top plate 12 to drive the sealing rubber plug 7 to separate from the delivery pipe 9, so that the lubricating oil inside the centralized cavity 10 can be dripped onto the top of the first gear 14 and the second gear 16, completing the intermittent lubrication work of the first gear 14 and the second gear 16. Moreover, when the circulating pump 15 is started, the lubricating oil at the bottom end of the protective cavity 13 can be discharged into the inside of the centralized cavity 10 again, so that the lubricating oil can be reused to prevent energy waste.
