Problems solved by technology

However, since the positioning wheel iron piece and the cam iron piece are inserted into the plastic kit later, there are the following defects: one is that the positioning wheel iron piece and the cam iron piece are not fixed firmly; wrong question
However, during use, it was found that the strength of the pillar replacing the cam was not enough, which affected the service life of the reversing switch

Abstract

The invention discloses a rotary shaft assembly for a reversible switch. The rotary shaft assembly comprises a metal rotary shaft, wherein a plastic sleeve part formed through injection molding is fixed on the metal rotary shaft; a positioning wheel iron sheet, a first cam 01 iron sheet, a second cam 01 iron sheet, a third cam 01 iron sheet, a fourth cam 01 iron sheet and a cam 02 iron sheet are inlayed on the plastic sleeve part synchronously; the metal rotary shaft, the plastic sleeve part, the positioning wheel iron sheet, the first cam 01 iron sheet, the second cam 01 iron sheet, the third cam 01 iron sheet, the fourth cam 01 iron sheet and the cam 02 iron sheet are integrated. The rotary shaft assembly product for the reversible switch has the advantages of less parts, simple structure, abrasion resistance, long mechanical service life, low production cost and the like; a problem of radial rotation between the cam and the rotary shaft is avoided; an assembling procedure for the rotary shaft is saved; a technical problem caused by incorrect part assembling of the rotary shaft is overcome.

Description

technical field [0001] The invention relates to a rotating shaft assembly for a reversing switch and a manufacturing method thereof, in particular to a rotating shaft assembly for a HY2 series reversing switch and a manufacturing method thereof. Background technique [0002] At present, the known reversing switches on the market are mainly composed of a housing, a base, a moving contact, a static contact, a rotating shaft assembly, an insulating part, a standard part, an operating machine, and the like. The rotating shaft assembly is composed of rotating shaft, iron core shaft, pins, positioning parts, bushings, cams, flat washers, spring washers, nuts, etc. The rotating shaft assembly has a large number of parts and a relatively complicated structure, and there is a radial gap between the cam and the rotating shaft. The problem of rotation; due to the problem of radial rotation between the cam and the shaft, the reverse switch product is easy to wear, which directly affects...
