Abstract

The invention discloses a bearing bush friction wear testing machine and a testing method thereof. The bearing bush friction wear testing machine comprises a bracket, a driving device, a testing device, a loading device, a measuring device and a lubricating oil circulation supply device, wherein the driving device, the testing device, the loading device, the measuring device and the lubricating oil circulation supply device are mounted in the bracket. The bearing bush friction wear testing machine disclosed by the invention has the advantages that the bearing bush friction wear testing machinecan simulate actual working conditions, effectively control loads and accelerate friction wear test; and meanwhile, by using relative rotation of a bearing bush in the friction process, the frictionforce bore on the bearing bush is accurately measured by using a guide rail type force sensor.

Description

technical field [0001] The invention relates to a bearing pad friction and wear testing machine and a testing method thereof, which can be used for detection and optimization of bearing pad lubrication friction in actual working conditions, and belong to the technical field of tribology. Background technique [0002] The bearing pad is the contact part of the sliding bearing and the journal. It is shaped as a tile-shaped semi-cylindrical surface and is divided into an upper half bearing pad and a lower half bearing pad. Its main function is to withstand the external force exerted by the journal, keep the oil film stable, make the bearing work smoothly and reduce the friction loss of the bearing. It is widely used in engines, diesel engines, axles and other medium and high load, medium and low speed equipment. It is the most widely used in industrial applications. , One of the most important parts. [0003] Most of the normal wear of the bearing bush occurs in the engine sta...
