Wear-resistant tooth ring

Abstract

The utility model discloses a kind of wear-resistant gear rings related to gear ring technical field, including gear ring body, the gear ring body is composed of annular plate and external gear, the outer diameter of annular plate is equal to the inner diameter of external gear, multiple limit grooves are set on the inner ring side wall upside of external gear, multiple limit blocks are fixedly connected with the outer ring side wall upside of annular plate, multiple limit blocks are respectively and multiple limit grooves one-to-one corresponding, limit block and limit groove are mutually adapted, the upper and lower sides of gear ring body are provided with the fixed mechanism acting on gear ring body, the utility model is by unique structure design, so that gear ring body is formed by annular plate and external gear splicing, can be freely disassembled, when the outer ring of gear ring body appears abrasion, only need to replace the external gear of gear ring body, when the annular plate of gear ring body appears abrasion, only need to replace the annular plate of gear ring body, to effectively reduce the replacement cost of gear ring body.
