Oil bearing pressure plate, oil bearing end cover assembly and motor

Abstract

The invention is suitable for the field of motors, and discloses an oil bearing pressure plate, an oil bearing end cover assembly and a motor. The oil bearing pressure plate comprises an annular substrate and a plurality of convex claw plates, wherein the plurality of convex claw plates extend upwards along the inner edge of the annular substrate; the claw plates are stepped bending plates; each claw plate comprises a transitional connection plate and a resisting plate; each transitional connection plate is tipsily bent upwards to extend along the inner edge of the annular substrate; and each resisting plate is bent upwards to extend along the end part, far away from the annular substrate, of each transitional connection plate and is used for being in resisting fit with an oil bearing. The claw plates are designed into the form of the stepped bending plates; and through weighted equivalent deformation of the transitional connection plates and the resisting plates, the contact angle between each resisting plate and the oil bearing can be effectively increased, so that the oil bearing can be automatically aligned under the condition that the motor deviates from the center due to the action of external force; the phenomena of sticking and burnout of the motor are avoided; the service life of the motor is ensured; the oil bearing pressure plate is low in improvement cost, and easy to realize; and noise of the motor is not increased.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to an oil-impregnated bearing pressure plate, an oil-impregnated bearing end cover assembly with the oil-impregnated bearing pressure plate, and a motor with the oil-impregnated bearing end cover assembly. Background technique [0002] Such as Figure 6-9 As shown, in the motor of an existing pulsator washing machine, the installation method of the oil bearing 2' is as follows: one end of the oil bearing 2' is pressed against the inner wall of the end cover 3', and the other end passes through the oil bearing pressure plate 1 ’, and the outer edge of the oil bearing pressure plate 1’ is pressed and fixed on the end cover 3’ through the oil storage cover 4’. Among them, the oil-impregnated bearing pressure plate 1' includes an annular base plate 11' clamped between the end cover 3' and the oil storage cover 4' and eight spacer rings are arranged inside the annular base plate 11' for...
