Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to an easily maintainable speed reducer and its support. Background Technique

[0002] Gear speed reducers are generally used in transmission equipment with low speed and high torque. Ordinary speed reducers for motors also have several pairs of gears with the same principle to achieve an ideal speed reduction effect. The ratio of the number of teeth of the large gear to the small gear is the transmission ratio. With the continuous development of the speed reducer industry, more and more enterprises are using speed reducers.

[0003] The existing speed reducer housing is tightly connected through multiple bolts. During the installation process, it is necessary to sequentially install bolts and nuts that match the bolts. The installation process is cumbersome, and during the maintenance of the speed reducer, the installation and disassembly of the bolts take a lot of time. Content of the Utility Model

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:
