Abstract

A bearing coupler assembly that has a bearing housing sized to at least partially receive a bearing assembly, the bearing housing defining a bearing axis therethrough, a shaft positioned at least partially through the bearing housing along the bearing axis, the shaft defining a shaft lip and a fastener end, the bearing assembly coupling the shaft to the bearing housing so the shaft can rotate about the bearing axis relative to the bearing housing, a fastener configured to be coupled to the fastener end of the shaft, a tone wheel positioned axially along the bearing axis between the fastener and the bearing assembly, the tone wheel having at least one indicator, a sensor coupled to the bearing housing and configured to identify when the indicator passes thereby.

First claim

The invention claimed is:

1. A bearing coupler assembly, comprising:
a bearing housing sized to at least partially receive a bearing assembly, the bearing housing defining a bearing axis therethrough;
a shaft positioned at least partially through the bearing housing along the bearing axis, the shaft defining a shaft lip and a fastener end, the bearing assembly coupling the shaft to the bearing housing so the shaft can rotate about the bearing axis relative to the bearing housing;
a motor shaft coupler defined in the shaft, the motor shaft coupler comprising a splined recess defined within the shaft;
a fastener configured to be coupled to the fastener end of the shaft;
a tone wheel positioned axially along the bearing axis between the fastener and the bearing assembly, the tone wheel having at least one indicator;
a sensor coupled to the bearing housing and configured to identify when the indicator passes thereby;
wherein, the tone wheel rotates with the shaft and the sensor is configured to identify the rotation speed of the tone wheel;
further wherein, the fastener applies a force on the tone wheel towards the shaft lip to provide an axial load to the bearing assembly.

2. The bearing coupler assembly of claim 1 , further comprising a sensor port defined in the bearing housing, wherein the sensor port establishes a calibration distance to the tone wheel.

3. The bearing coupler assembly of claim 1 , further wherein the at least one indicator is a radial extension defined in the tone wheel.

4. The bearing coupler assembly of claim 1 , further wherein the at least one indicator includes a plurality of radial extensions defined in the tone wheel.

5. The bearing coupler assembly of claim 1 , further wherein the fastener end of the shaft is threaded and the fastener is a nut, wherein the nut is threadably coupled to the fastener end at a torque value to apply the force on the tone wheel.

6. The bearing coupler assembly of claim 1 , further wherein the tone wheel directly contacts the fastener.

7. The bearing coupler assembly of claim 1 , further wherein the fastener applies the force to the tone wheel towards the bearing assembly to compress the bearing assembly between the tone wheel and the shaft lip.

8. The bearing coupler assembly of claim 1 , further wherein the bearing assembly comprises at least one tapered roller bearing.

9. The bearing coupler assembly of claim 8 , further wherein the bearing assembly comprises a first tapered roller bearing and a second tapered roller bearing.

10. The bearing coupler assembly of claim 9 , further wherein the first and second tapered roller bearings are positioned substantially one-hundred and eighty degrees opposed to one another along the bearing axis so an inner race of the first bearing contacts the tone wheel and an inner race of the second bearing contacts the shaft lip.

11. The bearing coupler assembly of claim 1 , further wherein the motor shaft coupler is defined at least partially radially inward of the tone wheel.
