Abstract

The attachment device comprises a base plate which is magnetically engaged to an end of a rotating shaft, the plate having a centered collar which is coaxial with the axis of the shaft and is configured to engage a rotatable spindle of a sensor mount to the shaft with the spindle being rotated by rotation of the shaft.

Claims

1. An attachment device for engaging a sensor mount including a rotatable spindle to an end of a rotating shaft, the device comprising a base plate including magnets therein and a centered collar extending outwardly of the base plate, the collar having a bore therein for functionally engaging the spindle of the sensor mount, with the magnets in the base plate engaging the device to the end of the rotating shaft in a manner such that the spindle is axially aligned with and rotated by rotation of the shaft.

2. The device of claim 1 wherein the device is unitary.

3. The device of claim 1 wherein the bore in the collar is threaded.

4. The device of claim 1 wherein the base plate has a hollowed out face.

5. The device of claim 4 wherein the magnets are seated within the hollowed out face in a radial array.

6. The device of claim 5 wherein the magnets are engaged within the face by an epoxy.

7. The device of claim 1 wherein the base plate and collar are separate structures.

8. The device of claim 7 wherein the base plate has a center orifice therein.

9. The device of claim 8 wherein the collar has an inner end which extends through the orifice in the base plate and is formed or rolled over the base plate between the magnets.

10. The device of claim 8 wherein the collar has a secondary threaded bore which aligns with the center orifice in the base plate, the collar being fixed to the base plate with a threaded connector.

11. The device of claim 10 wherein the threaded connector is a bolt.
