Abstract
A rotary position encoder is described that includes a hub configured to mount on an end of a rotatable shaft of a machine tool and rotate concurrently with the rotatable shaft. The hub includes a cup formed in a first end to receive the rotatable shaft, the cup having equally spaced axial grooves formed on an inner surface. A collar clamps the hub to the rotatable shaft by collapsing the cup around the rotatable shaft. The rotary position encoder further includes a sensor configured to detect a rotational position of the hub and a housing, wherein the sensor is mounted to the housing in a position opposite a second end of the hub. The hub is rotatably coupled to the housing via a bearing and a bracket is attached to the housing for mounting the rotary position encoder to the machine tool and preloading the bearing.
