[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 , an end cover for a planetary reducer is provided, the end cover is used to be connected to a housing 40 of the reducer, a plurality of holes 41 are provided on the housing 40, and the holes 41 are stepped holes, including a large hole at the outer end and a small hole with an internal thread at the inner end. This end cover is used to solve the problems of inconvenient installation and poor sealing. The specific implementation of the present application is described in detail below in combination with specific embodiments.
