Embodiment 1
[0034] Such as figure 1 As shown, the motor for eliminating electric corrosion of bearings according to the present invention includes a housing 1 and a motor stator 6 inside it, a motor rotor 5, and a rotating shaft 3, and the two ends of the housing are respectively equipped with a first end cover 2 and a second end cover. Cover 7, one end of the rotating shaft 3 fits through the first end cover 2 through the first bearing 4, the other end of the rotating shaft 3 fits with the second end cover 7 through the second bearing 9, and the second end cover 7 is externally fixed There is a cover plate 8 , and the end surface of the other end of the rotating shaft is electrically connected with the cover plate 8 through an elastic component 10 .
[0035] Such as figure 2 Said, the elastic assembly 10 includes a thimble 10-1, a spring 10-2 and a syringe 10-3, one end of the syringe 10-3 is fixed to the cover plate 8, and the spring 10-2 is placed in the syringe 10-3 Inside, one end...
Embodiment 2
[0039] Such as image 3 As shown, the elastic assembly 10 of this embodiment also includes a thimble 10-1, a spring 10-2 and a needle cylinder 10-3. The difference from Embodiment 1 is that the end surface of the rotating shaft in contact with the thimble 10-1 is processed with a very small The outer diameter of the boss 10-4, the thimble is in radial contact with the boss.
Embodiment 3
[0041] Such as image 3 As shown, the elastic component 10 of this embodiment adopts a spring piece 10 - 5 , one end of the spring piece 10 - 5 is in contact with the cover plate 8 , and the other end is in contact with the end surface of the rotating shaft 3 . The included angle α between the spring leaf 10-5 and the cover plate 8 is larger before the cover plate is installed than after installation, which is equivalent to the principles of embodiments 1 and 2, and the spring leaf can be adjusted to compensate for position changes.
