Abstract

The utility model relates to a kind of slip ring carbon brush brush box structure, it comprises phase ring, brush box support bar, brush box and carbon brush, each brush box is provided with side by side two carbon brush, brush box is arranged on brush box support bar, same phase ring is provided with two or more brush box, and described brush box is along phase annulate shaft to Heterogeneous Permutation.The utility model to misplace vertically arrangement due to carbon brush brush box on same phase ring, phase ring surface and carbon brush are in operation even wearing, avoid producing independently groove at phase ring surface, prevent the carbon brush on phase ring from upspringing, cause loose contact so that slip ring electric discharge scaling loss, extend the useful life of slip ring.

Description

A kind of slip ring carbon brush brush box structure

Technical field

The utility model relates to field of motor manufacturing, especially relates to a kind of slip ring carbon brush brush box structure.

Background technology

At present, winding motor is equipped with slip ring on rotor, slip ring is mainly used in the input of the electric current of rotor or draws, slip ring is primarily of three phase rings, multiple carbon brush, brush box forms, every two carbon brush are arranged on a brush box side by side, the centre, position of brush box being installed carbon brush is provided with dividing plate, during operation, multiple carbon brush rubs with phase loop contacts simultaneously, existing brush box is parallel arrangement on phase ring, the contact of every two carbon brush and phase ring is all in the surface of same phase ring, after running after a while, the surface of phase ring can produce two darker grooves, when slip ring vibrates, groove both sides chimb and carbon brush collide, carbon brush all on phase ring is caused to be upspring, cause loose contact so that slip ring electric discharge scaling loss, in addition, time the groove of phase ring may wear to a certain degree, must again change, useful life is lower.

Utility model content

The purpose of this utility model is to overcome above defect, provides a kind of phase ring even wearing and life-span longer slip ring carbon brush brush box structure.

The technical solution of the utility model is, a kind of slip ring carbon brush brush box structure, it comprises phase ring, brush box support bar, brush box and carbon brush, each brush box is provided with side by side two carbon brush, brush box is arranged on brush box support bar, same phase ring is provided with two or more brush box, and brush box is along phase annulate shaft to Heterogeneous Permutation.

Technique effect of the present utility model is, because carbon brush brush box misplaces vertically arrangement on same phase ring, phase ring surface and carbon brush are in operation even wearing, avoid producing independently groove at phase ring surface, prevent the carbon brush on phase ring from upspringing, cause loose contact so that slip ring electric discharge scaling loss, extend the useful life of slip ring.
