초록

An apparatus for preventing movement of a wheel on a shaft comprises a nut concentrically disposed on the shaft. A spring is disposed on the shaft and is operatively adjacent to the nut such that the spring can be biased towards the wheel. A first clamping ring is concentrically disposed on the wheel, with the first clamping ring being operatively adjacent the spring. A second clamping ring is operatively adjacent to the side of the wheel that is opposite to the first clamping ring, and a raceway is disposed between the shaft and wheel.

청구항

1. A method of preventing movement of a first wheel on a shaft without the use of a tie-bolt, comprising:moving a first nut disposed on said shaft, said moving being towards said wheel; contacting said first nut with a first spring disposed on said shaft; biasing said first spring towards a first side of said first wheel; disposing a first clamping ring at said first side of said first wheel; disposing a second clamping ring at a second side of said first wheel, said second side being opposite to said first side; whereby radially and axially directed mov...
