Title: Back-lash preventing mechanism of shaft joint
Inventor: OKAZAKI KAZUHIKO
IPC: F16D1/02
Filed: 1977-10-20
Abstract: PURPOSE: To provide a back-lash preventing mechanism for a shaft joint which can facilitate the relative alignment of joint members.  
     CONSTITUTION: When a joint member is axially positioned and a fastening bolt 3  is fastened at that position, a concave joint 7 is finely driven counter-clockwise, as  seen from the drive side, to an extent corresponding to the back-lash whereas a  convex joint 6 is also finely turned clockwise to the same extent until their spline  surface abut by the component of the force of the inclined surface of a sedge-shaped  convex portion 82 of a convex member 8. If it is assumed that the angles of contact  satisfy the relationship of α=β and that the coefficient of friction at the contact  surface of the flange portions 71 and 61 of the joints 6 and 7 is denoted at μ, then  the relationship of μ <1/tanα. Then, in case the bolt 3 is fastened, the perpendicular component of force, which is generated by the inclined surface pressure  of the member 8 as a result of the fastening force and which is applied to the bolts  of the joints 6 and 7', is higher than the frictional force of the contact surface between the two joints so that these joints can be prevented from axial movements.  Thus, it is possible to prevent the back-lash between the spline 43 of a driven shaft  4 and the splines 73 and 63.
