摘要： A hydraulic device includes a gerotor assembly, a wobble stick, an output shaft, a housing assembly, a first port in the housing assembly, a second port in the housing assembly, first brake disks, second brake disks, a piston, and a biasing member. The gerotor assembly includes a rotor and a stator. The wobble stick connects at a first end to the rotor. The output shaft connects to a second end of the wobble stick The housing assembly receives the gerotor assembly, the wobble stick and the output shaft. The first port is in communication with the gerotor assembly. The second port is also in communication with the gerotor assembly. The first brake disks connect to the output shaft The second brake disks connect to the housing assembly. The piston is disposed in the housing assembly adjacent at least one of the brake disks.

摘要： A hydrostatic transmission assembly includes a first gerotor motor, a pump housing, a first variable displacement pump, a second gerotor motor, and a second variable displacement pump. The first gerotor motor includes a first output shaft aligned along a first axis. The pump housing connects to and contacts the first gerotor motor. The first variable displacement pump includes a first driven shaft mounted to the pump housing and aligned along a second axis, the second axis being generally perpendicular to the first axis (the first output shaft axis). The first variable displacement pump is in fluid communication with the first gerotor motor via passages in the pump housing. The second gerotor motor includes a second output shaft generally aligned along or generally parallel to the first axis. The second gerotor motor is connected to the pump housing on an opposite side of the pump housing as the first gerotor motor. The second variable displacement pump includes a second driven shaft mounted to the pump housing and aligned generally parallel to the second axis. The variable displacement pump is in fluid communication with the second gerotor motor via passages in the pump housing.

摘要： A method for manufacturing roller pockets in a stator of a gerotor device generally includes providing a stator having a cavity including a generally cylindrical section defining a central axis and a plurality of roller pockets angularly spaced around a periphery of the cylindrical section. Each roller pocket is configured to receive a respective roller, which acts as an internal tooth of the gerotor device. Each roller pocket defines a generally cylindrical roller pocket bearing surface. The method further includes grinding each roller pocket bearing surface of each roller pocket with a grinding wheel rotating about a rotational axis perpendicular to the central axis. A stator for a gerotor device is also described.
