機の回期装置。[Claims for Utility Model Registration] A synchro hub fixed to a shaft, a coupling sleeve spline-coupled to the synchro hub via a key, and an outer bow ring disposed inside the spline portion of the synchro hub. and a synchro cone interposed between the inner baulk ring and the outer baulk ring and the inner baulk ring so as to be able to frictionally engage with both rings, and a clutch gear that is engaged with the synchro cone in the rotational direction. In the synchronizing device for a gear type transmission, the outer cone angle θout, which is the angle of the frictional engagement surface between the synchro cone and the outer balk ring with respect to the rotation axis, is set so that tanθout>μ(
μ: cone surface friction coefficient), whereas the inner cone angle θIN, which is the angle of the frictional engagement surface between the synchro cone and the inner balk ring with respect to the rotation axis, is set to tanθIN<μ, and the inner side cone angle θIN is set to tanθIN<μ. The balk ring is rotationally engaged with the engaged member with a gap of at least 1/2 the length of the sleeve spline in the rotation direction, and the synchro cone is rotated with respect to the clutch gear with a gap of at least 1/2 the pitch of the sleeve spline. 1/
A rotation device for a gear type transmission characterized by having a gap of 2 pitches and having wedge-shaped ends of the engaging portion.
