Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a speed reducer that is easy to maintain. Background Technology

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

[0003] Existing gearbox housings are typically made of one-piece cast iron. When subjected to external impacts, the housing is often damaged. Once damaged, the one-piece cast iron housing is usually difficult to repair. The working environment of the gearbox makes it virtually impossible to completely avoid such external collisions. Furthermore, damage to the housing will leave internal precision parts unprotected. Over time, this will lead to unusually frequent maintenance work, continuously increasing the workload of maintenance personnel and causing certain economic losses to the company.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: a speed reducer that is easy to maintain, including a base 1 and a fixing plate 8. A lower base 4 5 is fixedly installed on the top surface of the base 1. A lower base 3 4, a lower base 2 3, and a lower base 4 5 are threadedly installed on the right side of the lower base 4 5 by fixing bolts 10. Limiting blocks 6 are fixedly installed on the front and rear sides of the lower base 1 2, lower base 2 3, lower base 3 4, and lower base 4 5. A positioning block 7 is fixedly installed on the top surface of the lower base 1 2 and lower base 3 4. An upper cover 9 is provided on the upper side of the lower base 1 2, lower base 2 3, lower base 3 4, and lower base 4 5. Through holes 1 are provided on the sides of the lower base 2 3 and lower base 3 4. 1. A connecting block 13 is provided on the side of the lower base 1. A rotating gear 12 is fixedly installed on the side of the connecting block 13. A transmission gear 19 is meshed on the lower side of the rotating gear 12. A connecting rod 17 is fixedly installed on the side of the transmission gear 19. A transmission gear 16 is provided at the end of the connecting rod 17 away from the transmission gear 19. A fixing nut 18 is threaded on the side of the transmission gear 16. A motor baffle 20 is fixedly installed on the top surface of the base 1. A rotating roller 15 is fixedly installed on the side of the motor baffle 20. A fixing gear 14 is fixedly installed on the side of the rotating roller 15 away from the motor baffle 20. A cover plate 21 is provided on the top side of the motor baffle 20.

[0025] Furthermore, a fixing block 801 is fixedly installed on the inner side of the fixing plate 8.

[0026] With the above technical solution, when the top cover 9 is closed, the fixing block 801 will lock the limiting blocks 6 fixedly installed on the front and rear sides of the lower base 1 2, lower base 2 3, lower base 3 4, and lower base 4 5. When it is necessary to open the top cover 9, the lower end of the fixing plate 8 is slightly pried open so that the outer side of the fixing block 801 is away from the outer side of the limiting block 6.

[0027] Furthermore, a positioning groove 901 is provided on the bottom surface of the top cover 9.

[0028] By using the above technical solution, placing the upper cover 9 according to the position of the positioning groove 901 can prevent the upper cover 9 from tilting.

[0029] Furthermore, the connecting rod 17 passes through the perforation 11.

[0030] Through the above technical solution, the connecting rod 17 can be installed using the height of the through hole 11, saving space in the base.

[0031] Furthermore, a groove 2001 is provided on the side of the motor baffle 20.

[0032] With the above technical solution, when the cover plate 21 is placed on the upper side of the motor baffle 20, the fixing piece 22 can be inserted into the groove 2001 to fix the cover plate 21.

[0033] Furthermore, a motor is provided on the inner side of the motor baffle 20.

[0034] The above technical solution enables the motor to drive the gears to rotate and decelerate.

[0035] Working principle: When maintenance of the reducer is required, slightly pry open the lower end of the fixing plate 8, lift the front and rear ends upwards, unscrew the fixing bolts 10, remove the lower base 1 2, lower base 2 3 and lower base 3 4, loosen the fixing nut 18 on the outside of the connecting rod 17 and remove the transmission gear 1 16. At this time, the connecting rod 17 can be taken out from the through hole 11. After pulling the fixing plate 22 out of the groove 2001, the cover plate 21 can be opened and removed. After all parts are removed, the reducer can be repaired and maintained.
