Benefits of technology

The TEG system enables continuous electrical power generation from thermal energy, enhancing the efficiency of bearing assemblies by focusing heat through liquid cooling systems and reducing the need for external power, making it suitable for remote and temporary installations.

Problems solved by technology

Batteries provide a limited capacity, which dictates a limited supply and thus a limited run time.
Obtaining power from a commercial utility source can be costly, particularly for remote installations.
Transferring electrical power from a commercially available source can require running extensive and costly power cabling and support equipment.
Replacement of batteries incurs both parts and labor costs.
During operation, the bearing can generate a significant amount of heat.
The application of the bearing may limit the availability or ease of providing electrical power to the sensors used to monitor the condition of the bearing.

Abstract

A power generating bearing assembly provides a bearing subassembly retained by a bearing housing. During operation, friction and other factors increase a temperature of the bearing assembly. The bearing housing can optionally include a bearing cooling passage system comprising at least one liquid cooling passage which would be integrated within the bearing housing. The liquid cooling passage would be routed proximate the bearing subassembly to remove heat therefrom. A Thermo-Electric Generator (TEG) is thermally coupled to an exterior surface of the housing at a location identified for collecting heat generated during operation. The Thermo-Electric Generator (TEG) utilizes a temperature difference between the housing and the ambient air to generated electric power. The power can be used to operate electrically powered devices, such as condition sensors, communication devices, and the like.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field of the Invention[0002]The present invention relates to an apparatus and method for generating power utilizing a Thermo-Electric Generator (TEG) to convert thermal energy generated by rotation of a bearing within a bearing housing into electric energy.[0003]2. Background Art[0004]Bearings are used to support many rotating objects. Bearings are commonly integrated into a variety of machines. The bearings are a key factor contributing to the reliability of the machine. The system designed commonly installs one or more bearing condition monitoring devices to ensure the bearings remain in working order. The majority of the condition monitoring devices requires low voltage electrical power for operation. Some systems include other components that also utilize electrical power. One such electrically operated component can be a communication device for transferring the condition monitoring information to a remote service company.[0005]Bear...
