ATTACHMENT POINT OF CROWN GEAR IN PLANETARY OR DIFFERENTIAL REDUCER

摘要

FIELD: machine building. ^ SUBSTANCE: attachment point of crown gear in planetary of differential reducer consists of crown gear (1) coupled with hub (2) of crown gear by means of tooth coupling. Height of teeth of crown gear (1) is equal to height of teeth of hub (2). Groove (3) is made in rim of crown gear (1) wherein there is installed spring ring (4), while a slot is made on end surface of crown gear (1). Spring ring (4) is split; its ends are bent upward and enter the slot of crown gear (1). Circular groove (7) is cut in the rim of hub (2). ^ EFFECT: reduced axial length of tooth coupling of crown gear and hub of crown gear and increased reliability of tooth coupling. ^ 2 dwg
