Injection molding ABS gear ring with winding spiral induction teeth and production method thereof

Abstract

The invention discloses an injection molding ABS gear ring with winding spiral induction teeth and a production method thereof. The injection molding ABS gear ring comprises a filling ring seat, wherein the filling ring seat is formed into a circular ring shape through injection molding, and an inner hole is formed in the middle of the filling ring seat so as to facilitate the assembly of the ABSgear ring. The injection molding ABS gear ring is characterized in that a circular-ring-shaped winding spiral body is embedded in the filling ring seat 3; the winding spiral body is made of soft magnetic material wires with rectangular sections; the circle center of the circular-ring-shaped winding spiral body coincides with the circle center of the filling ring seat; and the induction teeth whichare pressed into a plane and are distributed at equal intervals are arranged on the winding spiral body. According to the injection molding ABS gear ring, the soft magnetic material wires with the rectangular sections are adopted, the winding spiral induction teeth which are uniformly distributed and arranged into a ring shape are manufactured, and the outer side of the winding spiral induction teeth is wrapped with an injection molding material, so that the production efficiency is improved, and the manufacturing cost is reduced; and meanwhile, the plastic is adopted for wrapping and injection molding into a whole, so that the overall weight is light, and the weight reduction of a vehicle is facilitated.

Description

technical field [0001] The invention relates to an improvement of a production method of an ABS ring gear, in particular to an injection molded ABS ring gear with winding helical induction teeth and a production method thereof. Background technique [0002] The ABS ring gear is an indispensable part of the anti-lock brake system of the automobile. There are three main methods for the production of the existing ABS ring gear: 1) Low carbon steel is manufactured by machining process; 2) Steel plate is stamped 3) Forming by powder metallurgy casting and pressing. [0003] After searching, Hangzhou Haixiangda Powder Metallurgy Co., Ltd. submitted a Chinese patent application "ABS ring gear combined with injection molding and metal" on December 17, 2015. The patent number is CN201521056166.1, which discloses that "its composition includes: metal ring gear and Injection molded ring gear, the injection molded ring gear includes an inner ring and an outer ring, there is a groove be...

AI Technical Summary

Problems solved by technology

[0007] The main problems of the current ABS ring gear are: low-carbon steel machined and formed, mostly produced by CNC machine tool milling, which has many production processes, low production efficiency, heavy product weight, and high cost; steel stamping formed, the product Low precision, easy to deform; formed by powder metallurgy, the product has large porosity, low strength and elongation, and poor impact resistance
