Benefits of technology

Enables accurate and repeatable preload adjustments for bearings, minimizing the impact of resistive drag torque and ensuring optimal bearing life by providing a reliable and precise method for applying and monitoring compressive loads, thus improving the efficiency of bearing assembly and maintenance processes.

Problems solved by technology

However, for several reasons, it is typically extremely difficult to achieve such preload settings under actual in-field conditions, such as in a mechanic shop.
For example, the assembly of a heavy truck wheel onto a wheel hub assembly is a relatively cumbersome procedure that hinders the mechanic.

Embodiment Construction

[0036]In accordance with the principals of the present invention, system and methods for adjusting bearings mounted on a shaft and aligning lock nuts for retaining such bearings are provided.

[0037]In an exemplary embodiment depicted in FIG. 1, a wheel hub assembly 10 engages a bearing preload apparatus 20. Some of a section of the hardware has been removed to reveal inner structure to facilitate disclosure of the invention. For the sake of illustration, the wheel assembly that would typically be mounted to wheel hub assembly 10 is omitted in these figures.

[0038]Wheel hub assembly 10 is an assembly that would typically be found on a front or rear axle of a cab or tractor of a tractor-trailer, or an axle of a trailer. However, aspects of the invention are not limited to use for vehicle bearings. As will generally be understood by those skilled in the art, aspects of the invention may be used to service bearings and bearing assemblies in any machine or device that employs bearings, inc...

Abstract

A system for providing a load on a bearing mounted to a shaft includes an attaching member releasably connectable to the shaft and a press mechanism in fluid communication with a source of fluid and configured to provide a compressive load to the bearing. The press mechanism includes a switch having a base and a piston in communication with the fluid such that an increase in a pressure of the fluid results in the piston extending upwardly from the base and a decrease in the pressure of the fluid results in the piston retracting toward the base. The switch includes a first lower proximity sensor and a second higher proximity sensor. The piston is configured to extend upwardly from the base past the first lower proximity sensor and to trip the second higher proximity sensor. The switch is configured to control the increase in the pressure in response to the piston tripping the higher proximity sensor.
