PURPOSE:To optionally displace a power transmission shaft in a range four times the displacement between the centers of each eccentric bearing and perform easy adjustment of its eccentricity, by supporting the power transmission shaft to a housing through two eccentric bearings. CONSTITUTION:An outer flange 6 is integrally provided to an outer eccentric bearing 2, and, for instance, six insertion holes 7 of bolt are provided at an equal space to the outer flange 6, then bolts 8 are inserted into each hole 7 and screwed to a housing 1 to fix the bearing 2. An inner eccentric bearing 3 is fitted to said bearing 2, and, for instance, six insertion holes 10 of bolt are formed at an equal space, then bolts 11 are inserted into each hole 10 and screwed to the bearing 2 to fix the bearing 3. In this way, the bearings 2, 3 are suitably rotated at an angle of each hole, that is, at a space of 60 deg., then a power transmission shaft 4 can be movably adjusted within a circle of radius 2delta (where delta for eccentricity) with the center O1 of the bearing 2, and a movably asjusting range can be spread. |
