Protecting jacket of collecting ring of motor

Abstract

The invention discloses a protecting jacket of a collecting ring of a motor, which relates to the tools used in the technology of motor production. The protecting jacket is a cylindrical body, an inner cavity of the protecting jacket is longer than a shaft end section, and the inner diameter of the protecting jacket is greater than the external diameter of the shaft end section; three radial rib plate strips extend inwards from an inner wall of the protecting jacket and distributed uniformly in a combination form, wherein the diameter surrounded by the front edges of the three rib plate strips is less than the external diameter of the shaft end section; and a bottom cover of the cylindrical body is centrally provided with a through hole. The protecting jacket of the collecting ring of the motor has the following advantage that: the protecting jacket and the shaft end section are sleeved together, which saves effort and ensures the tightness of the sleeved connection.

Description

Technical field: [0001] The invention relates to a craft tool in motor production, in particular to a motor collector ring protective sleeve. Background technique: [0002] The shaft end section of the motor shaft is fixed with two copper collector rings for conducting electricity when the motor shaft rotates. During production, after the two collector rings are fixed and installed, bumps will inevitably occur in the subsequent process, causing scratches or damage to the collector rings. Therefore, in the production process, a protective cover must be put on the collector rings after they are installed. [0003] The shape of the protective sleeve in the prior art is a tubular body, its inner diameter is theoretically equal to that of the shaft end section, and the length of the inner cavity is slightly longer than that of the shaft end section. After the protective sleeve is put on, one end of the protective sleeve is pushed against the shaft shoulder at the rear of the shaf...

AI Technical Summary

Problems solved by technology

The material of the existing protective sleeve is generally paper or plastic, and the inner diameter of the inner cavity cannot guarantee a tight fit with the shaft end. If the inner diameter of the inner cavity is small, it will not fit on it, and if it is too large, it will fall off. It is difficult to ensure that the size is just right. Good set without falling off
