Problems solved by technology

Conventional lubrication systems may therefore provide too much grease under certain conditions and under-lubricate under other conditions without adequate consideration of the rate at which the grease breaks down or degrades

Embodiment Construction

[0016] Referring now to the accompanying drawings, wherein the drawings are for purposes of illustrating presently preferred embodiments only and not for purposes of limitation, figure 1 Housing 10 is shown containing a bearing assembly 12 including an inner ring 14 , an outer ring 16 and a plurality of rolling elements 18 therebetween. Bearing assembly 12 supports shaft 20 for rotation relative to housing 10, and inner seal 22 and outer seal 24 seal within the housing a free volume 26 that is completely or substantially filled with a lubricant, such as lubricating fat. The free volume 26 includes the space inside the bearing assembly 12 where the grease is in contact with the rolling elements 18, the area immediately adjacent the shaft 20 where the grease is agitated as the shaft 20 rotates, and where the grease is not actively performing a lubrication function but where it Areas axially remote from bearing assembly 12 and radially remote from shaft 20 are movable along shaf...

Abstract

A bearing system includes a bearing housing configured to house a bearing, the bearing housing enclosing a free volume for receiving lubricant; a quantity of the lubricant in the free volume; a sensor configured to measure at least one parameter affecting a degradation rate at which the lubricant will degrade and to produce at least one output signal indicative of the measured at least one parameter; a pump for pumping lubricant into the bearing housing; and a controller configured to receive the at least one output signal from the sensor and to control the pump based a function of the received at least one output signal.

Description

technical field [0001] The present invention relates to a bearing system with a lubrication controller, and more particularly, to a bearing system with a lubrication controller configured to adjust a lubrication rate or interval based on a measured parameter affecting a lubricant degradation rate. Background technique [0002] Automatic lubrication systems are known which include mechanical dosing and pumping components. These components may be configured to provide a fixed dose of lubricant (grease or oil or other suitable lubricant, hereinafter generally referred to as "grease") at predetermined intervals. Intervals and doses are usually set by manual adjustment of each individual dosing device. US Patent Application Publication No. 2013 / 0015019A1, entitled "Advanced Lubrication System," discloses a lubrication system that provides greater control over lubricant dosing and more automated control, the disclosure of which is incorporated herein by reference. [0003] Conve...
