[0030] The specific embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0031] The following reference Figures 1 to 4 The utility model is described as follows:

[0032] A motor housing foot split type connecting structure, comprising a split type housing 10 and a plurality of feet 20;

[0033] The housing 10 comprises a cylindrical body 101, and a plurality of circumferentially distributed foot bases 102 are formed on the outer wall of the cylindrical body 101, and the feet 20 are inserted into the foot bases 102; the feet 20 and the foot bases 102 are fastened and connected through a screw assembly 40. The length specifications of the feet can be various, and the size specifications of the housing can also be various.

[0034] Through the split type setting of the feet and the housing, the feet can be fixed at any axial position on the housing through the screw assembly, and the entire motor can be conveniently adjusted in the axial direction; meanwhile, the feet and the housing are split type, the feet and the housing have multiple specifications, can be freely matched, realize the assembly requirements of multiple different working conditions, and can reduce the mold opening cost and the mold cost, and reduce the production difficulty.
