An apparatus combining the tests of lubrication systems with performance of rolling bearings is disclosed. The functions include the regulation of axial load and lubrication system and measurement of temperature rise and friction torque of test bearing which are provided to analyze the performance of test bearing under different axial loads, rotating speed and lubrication conditions. The test apparatus consists of loading, testing, linking, power, and base sections. In the loading section, a disc spring can be compressed by an adjustable screw to make up a mechanism for changing axial load on the test bearing. The testing section includes a thermocouple and a mechanism for measurement of friction torque of bearing. The outside of testing section has a protective sleeve for setting holes and pads which are adapted to fix, change and regulate the position, number, and outlet displacement of lubricant nozzles according to different lubrication systems and the actual testing needs. In the linking section, both ends of a rotating spindle connect with the power and the testing sections for delivering the rotating power and driving the test bearing.

Test apparatus for lubrication performance of rolling bearings

A configuration of lubrication nozzle including a large flow path to connect external oil supply tube with semi-circle cross section annular flow path, and three jet flow conduits with L form having interval of 120.degree. between adjacent channels to link annular flow path and outlet is created for oil-air or oil-mist lubrication system for high speed rolling-element bearings.
