More Information
Summary:The utility model relates to an eccentric shaft based on clearance adjustment of an air-pressure disk type brake. The eccentric shaft comprises a shaft body and an eccentric disk which does not have the same coaxial line with the shaft body. A first adjustment block or a second adjustment groove is arranged on or formed in an axial end face. Through a rotation shaft of a special structure and the cooperation of the adjustment block or the adjustment groove arranged on or formed in the axial end face and a corresponding bevel gear, the change quantity of the brake clearance is transmitted, as a result, the brake clearance can maintain a constant value, the stability of the braking performance is guaranteed, and the braking performance of the brake can be conveniently improved.
