Both were circular in shape. For this reason, the weights of the bearing metal member 4 and the positioning metal member 6 have increased. Furthermore, in case the bearing metal member 4 is worn out, a spare bearing metal member is prepared for repair.
Even when the annular bearing metal member 4 wears unevenly, the annular bearing metal member 4 must be replaced with a spare one, which poses a problem of high cost. In addition, especially in the case of the planetary gear system illustrated, the weight of the bearing is the weight of the power transmission system, so considering its responsiveness, it is desirable to reduce the weight of the bearing as much as possible. .
