DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following further elaborates on the utility model in conjunction with the drawings and specific embodiments.

[0014] As Figures 1-3 shown, a rubber enterprise retreader motor speed reducer includes a speed reducer 1, a lubricating oil filling port 2, a lubricating oil discharge port 3, a drive motor 4, a power output shaft 5, and a shock absorption support seat 6. A lubricating oil filling port 2 is opened in the middle of the top end of the speed reducer 1, a lubricating oil discharge port 3 is opened at the bottom right end of the speed reducer 1, a drive motor 4 fixedly hinged is installed at the bottom of the rear end of the speed reducer 1, an embedded power output shaft 5 fixedly hinged is installed in the middle of the front end of the speed reducer 1, and a shock absorption support seat 6 fixedly installed with bolts is installed at the bottom end of the speed reducer 1.

[0015] The speed reducer 1 includes a hollow sound-insulating box body 7, sound-insulating cotton 8, a high-strength support box body 9, a power input shaft 10, a helical gear set and a synchronizer 11. The inner side of the hollow sound-insulating box body 7 is provided with a cavity and filled with sound-insulating cotton 8 inside. The high-strength support box body 9 is installed inside the hollow sound-insulating box body 7. The power input shaft 10 hinged and fixed by bearings is installed inside the high-strength support box body 9. Helical gear sets and synchronizers 11 connected by keys are installed on the surfaces of the power output shaft 5 and the power input shaft 10, and power transmission is achieved through meshing.

[0016] The shock-absorbing support base 6 includes a rubber support plate 12, a limit buffer base 13, a split limit plate 14, a jack 15, a plug rod 16, a limit hole 17, a spring 18, a piston connecting rod 19, a limit block 20, a threaded connecting rod 21, and a rubber block 22. Two groups of welded limit buffer bases 13 are installed at the top of the rubber support plate 12. The split limit plate 14 fixed by screws is installed at the top of the limit buffer base 13.

[0017] The working principle of the present utility model: First, the power input shaft at the front end is driven to rotate by a driving motor, and then the power is decelerated in three different degrees by cooperating with the helical gear set and the synchronizer, and then output through the power output shaft. Then, during the working process of the speed reducer, the hollow sound-insulating box body with a sound-insulating cavity and the sound-insulating cotton cooperate to achieve the effect of reducing noise. Finally, the vibration generated by the speed reducer is initially buffered by the piston connecting rod rising and falling inside the limit buffer base, and then the piston connecting rod cooperates with the spring and the rubber block for secondary shock absorption and buffering during the rising and falling process. Finally, the rubber support plate is used as the third layer of buffer to further improve the shock absorption effect of the speed reducer.

[0018] The above is the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principles and spirit of the present utility model, the changes, modifications, substitutions, and variations made to the implementation manners still fall within the protection scope of the present utility model.
