Claims
- 1. An encoder retainer ring in combination with a magnetic encoder ring on a rotatable shaft, the magnetic encoder ring having a plurality of axially extending fingers, the encoder retainer ring comprising:
- an annular ring having a plurality of teeth extending radially inward to grip the rotatable shaft and having a plurality of spaces between the teeth, the magnetic encoder ring axially extending fingers extending through the annular ring spaces thereby coupling the annular ring to the magnetic encoder ring.
- 2. A magnetic encoder for use on a rotatable shaft, the magnetic encoder comprising:
- an annular magnetic encoder ring having a plurality of axially extending fingers; and
- a retainer ring, the retainer ring being an annular ring having a plurality of castellated teeth extending radially inward to grip the shaft and having a plurality of spaces between the teeth, the annular magnetic encoder ring axially extending fingers extending through the retainer ring spaces thereby coupling the retainer ring to the annular magnetic encoder ring.
