Abstract
An angle measuring system that includes a drive shaft that rotates about an axis of rotation, an encoder and an encoder attachment system that has a Belleville disk spring that generates a radial pressure with respect to the axis of rotation so as to attach the encoder to the drive shaft.
Claims19
An angle measuring system comprising:
- a drive shaft that rotates about an axis of rotation;
- an encoder;
- and
- an encoder attachment system comprising a Belleville disk spring that lies upon said drive shaft and generates a radial pressure with respect to said axis of rotation so as to attach said encoder to said drive shaft.

A method of attaching an encoder to a drive shaft that rotates about an axis of rotation, the method comprising:
- positioning said encoder adjacent to said drive shaft that rotates about said axis of rotation;
- and
- rotating a screw so as to compress a spring that generates a radial pressure with respect to said axis of rotation so as to attach said encoder to said drive shaft.
A method of attaching an encoder to a drive shaft that rotates about an axis of rotation, the method comprising:
- positioning an encoder adjacent to a drive shaft that rotates about an axis of rotation;
- and
- rotating a cap so as to compress a spring that generates a radial pressure with respect to said axis of rotation so as to attach said encoder to said drive shaft.
