Absolute angle sensor for multi-turn shaft |
摘要 |
A system for determining the absolute position of a multi-turn shaft is disclosed. The shaft is mounted in an elliptically shaped wave generator. The wave generator is coupled to a flex spline which is deformed to match the wave generator. The exterior surface of the flex spline has a number of gear teeth. The flex spline is installed within a cylindrical, circular spline. The circular spline has an interior diameter which is slightly larger than the largest diameter of the flex spline. The interior surface of the circular spline has a number of teeth which interlock with the teeth of the flex spline. In such a manner, the rotation of the shaft will cause an angular displacement of the circular spline. A position sensor is located on the circular spline and serves to track the position of the circular spline which is proportional to the absolute position of the shaft.
