回転流体圧装置
Document Type and Number:
Japanese Patent JP4235850
Kind Code:
B2
Abstract:
A gerotor motor (11) of the type having a spool valve (51) which is formed integrally with the output shaft (49), wherein the spool valve includes forward (67) and rearward (69) journal surfaces. Disposed radially between the output shaft (49) and a bearing-receiving portion (71) of the motor housing (13) is a ball bearing set (73), which is preloaded during assembly such that the rated side load on the output shaft (49) will not cause any substantial radial movement of the shaft within the bearing set (73). In order to reduce the length, and cost of the motor (11), the conventional wear plate adjacent the gerotor gear set (15) has been eliminated, such that both the valve housing (13) and the spool valve (51) are disposed immediately adjacent the gerotor gear set, and the rotating spool valve (51) is in engagement with the orbiting and rotating star member (27).
