Screw type hone assembly for the honing of gears

Claim 1

A screw type hone assembly for the honing of gears, comprising a substantially cylindrical body 24 of the hone having on the outer periphery a spirally threaded portion 61 possessing rigidity in entirety and mounted on a rotating shaft 41 of a honing apparatus for the integral rotation with said shaft 41, said cylindrical body 24 further having cylindrical end portions, each having an outer circumferential face; a honing grain layer 27 formed on at least the surface of the threaded portion 61 of the hone body 24 and adapted to hone the tooth surface of the gear; a cylindrical sleeve 12 detachably secured on a rotating shaft 41 for carrying the hone body 24 on the rotating shaft 41, said sleeve 12 having on one end portion thereof a retaining portion 13 which radially projects on the outer periphery and on the other end a retaining ring 16 substantially in the same shape as that of the retaining portion 13, said retaining ring 16 being urged toward said retaining portion 13 by nuts 15 threaded onto the sleeve 12 from outside the retaining ring 16, both said retaining portion 13 and said retaining ring 16 having cylindrical portions 28 and 29, respectively, extending axially inwardly from the respective outer peripheries in a face-to-face relation, each cylindrical portion having an interior circumferential surface overlapping and retaining the outer circumferential face of the respective cylindrical end portion of the body 24, whereby the hone body 24 is fixedly clamped between said retaining portion 13 and said retaining ring 16; and resilient members interposed between said hone body 24 and said sleeve 12, whereby said resilient members permit the body 24 to be elastically axially and radially movable on the rotating shaft 41.
