摘要： A gerotor motor of the type having an end cap (13), and a stationary valve plate (15) disposed adjacent a rearward surface of the gerotor gear set (17). Adjacent a forward surface of the gerotor star (27) is a balancing plate assembly (19) including a radially outer balance plate (73) and a radially inner balance plate (75), the balance plates defining inner (77) and outer (79) profiles, respectively, which are closely spaced apart and are radially inward from the gerotor volume chambers (29) to provide sufficient sealing land. The inner balance plate (75) is biased toward the star end surface (81) by a Belleville washer (87). The end surface (81) of the gerotor star (27) defines individual star tooth surfaces (97), each of which includes a radial fluid passage (99) receiving system pressure, and a fluid passage (101) oriented generally perpendicular to the radial passage, and having a decreasing flow volume in a direction away from the radial passage (99). The fluid flowing through the perpendicular fluid passage (101) substantially reduces the tendency for galling to occur between the end surface of the star and the adjacent surface of the balance plate (75).

摘要： A fluid pressure motor of the type including a gerotor gear set (15) including a star member (31) which orbits and rotates. The motor includes valving (41) which is disposed forwardly of the gerotor gear set, and an end cap assembly (21;111) disposed rearwardly of the gerotor gear set. The star member (31) defines a central opening (89;127) at the rearward end thereof, which may be defined by a separate insert member (125). Within the end cap assembly (21;111) is a lock piston (75;133) biased by a pair of Belleville washers (85, 87;121) toward an engaged position (FIG. 1; FIG. 4) in which a lock portion (79) has its beveled portion (91;135) in engagement with the central opening (89;127) of the star (31), thus preventing any further orbital motion of the star, and serving as a parking lock. The lock piston (75;133) and end cap assembly (21;111) define a pressure chamber (99;119) which may be pressurized by an external signal (95) to move the lock piston to its disengaged position (FIG. 2) in which the beveled portion (91;135) is out of engagement with the central opening (89;127), and the star member (31) is permitted to orbit and rotate in the normal manner.
