the technical scheme in the invention for solving the technical problem is: a kind of bearing is difficult for the motor of slip, described motor comprises a shell, be connected in the front end housing assembly of shell front end, be connected in the rear end cap assembly of outer casing back, be located at the stator module on shell, described front end housing assembly is provided with front-axle hole, described rear end cap assembly is provided with rear axis hole, be equipped with main shaft in described front-axle hole and rear axis hole, be provided with the fore bearing of the described main shaft of supporting between described front-axle hole and main shaft, be provided with the rear bearing of the described main shaft of supporting between described rear axis hole and main shaft, the bearing outer ring of described fore bearing and front end housing assembly contact position are provided with the first locating ring, the bearing inner race rear side of described fore bearing is provided with the first snap ring, on described main shaft, corresponding the first snap ring position is provided with the first draw-in groove, described the first snap ring inboard is arranged in the first draw-in groove, the bearing outer ring of described rear bearing and rear end cap assembly contact position are provided with the second locating ring, the bearing inner race front side of described rear bearing is provided with the second snap ring, on described main shaft, corresponding the second snap ring position is provided with the second draw-in groove, and described the second snap ring inboard is arranged in the second draw-in groove.
Described the first snap ring and the second snap ring can adopt the metal snap ring of high resiliency.
Further, also be provided with the first adjustment ring between the bearing outer ring of described the first locating ring and fore bearing, also be provided with the second adjustment ring between the bearing outer ring of described the second locating ring and rear bearing.Described the first adjustment ring and the second adjustment ring can be selected bending or with the metallic elastic sheet of radian, and that can adopt also that nonmetallic materials make plays the effect of adjusting described bearing clearance, convenient installation on the different size motor.
the utility model is consistent with the motor of prior art in use, it is fore bearing, rear bearing when mounted, with fore bearing, rear bearing is by the first locating ring, the second locating ring is attached to the front end housing assembly, on the rear end cap assembly, the first draw-in groove on main shaft, the second draw-in groove is embedded in the first snap ring, the second snap ring, then with the front end housing assembly, the rear end cap assembly is pressed on main shaft, the inner ring of bearing presses to the first snap ring and thereby the second snap ring is located front and back bearings, then front end housing assembly and rear end cap assembly are fixed on shell, because the first snap ring has certain elasticity, transfer gap and slow down the spindle vibration function therefore can play very easily.
The beneficial effects of the utility model are: adopt to have certain elasticity and can be out of shape and transfer the snap ring of gap that bearing is compressed, thereby can adaptively transfer gap to bearing, make bearing be not easy to slide.
