Classification of Non Circular Gears

Based upon different factors, non circular gears can be classified as follows:

Definitions by the geometrical character: enclosed type non circular gears, opentype non circular gears;

Definitions by the outlines: elliptical gears, triangular gears, square gears,multispeed gears, oval gears, eccentric gears, logarithmic spiral gears, cam gears;

Definitions by material: steel non circular gears, alloy steel non circular gears ,stainless steel non circular gears, aluminum non circular gears, bronze non

circular gears, brass non circular gears, PA non circular gears;

Definitions by processing methods: single-index method, double-index method,template method, generating method, high speed wire cut, slow speed wire cut,NC gear shaping;

How To Purchase Non Circular Gears:
