Internal gear grinding device based on steel-based abrasive belt

An internal gear grinding device based on a steel-based abrasive belt comprises a rack, a driving wheel unit and a driven wheel unit are arranged on the rack, the steel-based abrasive belt is wound on the driving wheel unit and the driven wheel unit, and an auxiliary pressing unit matched with the driving wheel unit or the driven wheel unit is further arranged on the rack. And the adjusting and supporting unit is matched with the steel-based abrasive belt and is arranged between the driving wheel unit and the driven wheel unit. The steel-based abrasive belt is used for machining the inner surface of the inner gear under the constraint of the adjusting supporting unit, the length of the steel-based abrasive belt can be made to be long by adjusting the distance between the driving wheel unit and the driven wheel unit, in this way, abrasion of some grinding wheel blocks does not affect overall use, and the service life of the abrasive belt can be prolonged; therefore, the cost of the steel-based abrasive belt ca
