FINISHING DEVICE FOR TOOTH SURFACE OF BEVEL GEAR

摘要

PURPOSE:To improve the tooth surface of a bevel gear reasonably so as to reduce a noise by providing the swing pivot shaft position of a bevel gear so as to pass the vertex of a basic pitch cone and swinging a swing plate which swings in an arc shape. CONSTITUTION:A swing plate 7 performs an arc shaped swinging motion in an arrow mark 15 direction by means of an eccentric cam 17 rotated by a motor with a swing pivot shaft 18 mounted on a swivel base 6 as a swing center through a flexible shaft. Consequently, the teeth of a bevel gear 12 geared with a bevel gear 11 perform a swing motion in an arrow mark 15 direction and a pair of bevel gears 11, 12 are lap-finished.
