Patent number: 5129797Abstract: An equal velocity universal joint is suitable for coupling shafts, driving and driven shafts, of mutual machines and for use in an axial piston pump motor device. One ends driving pins of the equal velocity universal joint rotate along a predetermined locus on a concentric circle while rotating and sliding by themselves in the cylinder bores of the driving or driven shaft. Spherical head portions of the other ends perform rotating motion in cylinder bores or ball receiving bores of the driving or driven shaft. Accordingly, the respective drving pins continue linear sliding motion in response to the rotation of the driving or driven shaft and thereby the spherical head portions of the other ends are held at the concentric circle on the driving or driven shaft so as to keep the driving center in floating state. As a result, the respective pistons are driven on a concentric circle, thereby an equal velocity universal joint is realized and the mechanical vibration thereof is substantially eliminated.Type: GrantFiled: May 21, 1991Date of Patent: July 14, 1992Assignee: Hitachi, Ltd.Inventor: Hisanobu Kanamaru
