    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.

    摘要： A method for deburring a ground metal part includes loading a ground metal part into a carrier, contacting a first planar surface of the ground metal part with a first grinding wheel, and contacting a second planar surface of the ground metal part with a second grinding wheel. The first grinding wheel is rotated in a first rotational direction. The second grinding wheel is rotated also in the first rotational direction. After the first grinding wheel is rotated in the first rotational direction, the first grinding wheel is then rotated in a second rotational direction, which is opposite to the first rotational direction. After the second grinding wheel is rotated in the first rotational direction, the second grinding wheel is also rotated in the second rotational direction.

    摘要： A return to neutral mechanism includes a hub, a lever and a biasing member. The hub is configured to connect fast to a control rod of an associated hydraulic pump. The lever connects to the hub and includes a location configured to connect to an associated linkage that is connected to an associated steering mechanism. The biasing member connects to the lever for biasing the lever and the control rod toward a neutral position.
