Abstract
A gear suspension system is disclosed that permits movement of a gear, such as a spiral bevel or hypoid gear relative to its pinion with six degrees of freedom. The gear suspension system includes a support structure with a moveable carriage mounted thereon. The carriage is supported by six actuators interconnected together to form three connection joints to the support structure and three connection joints to the gear carriage. The gear is mounted to the carriage for rotation about a central axis. The actuators allow the gear mounting distance, the shaft angle, the H position and the V position to be adjusted. In addition, the actuators further allow the gear carriage to be rotated about the central axis and to be rotated about an axis that is parallel to an axis of a pinion and passing through the central axis.
Claims11
An apparatus for testing and adjusting a position of a first gear with respect to a second gear relative to three substantially orthogonal axes, the first gear driving the second gear with the first gear driven by a rotational drive, the apparatus comprising:
- a frame on which the first gear and the rotational drive are mounted;
- a carriage for supporting the second gear for rotation about a central axis;
- actuator means connected to the frame for supporting the carriage relative to the first gear, the actuator means allowing movement of the second gear linearly along and rotationally about the three substantially orthogonal axes, wherein the actuator means is disposed on the frame to form three frame connection joints, and wherein the actuator means is disposed on the carriage to form three carriage connection joints;
- and
- sensing means to determine relative displacement of the second gear with respect to the first gear.
