Abstract

The invention discloses a polymer thrust bearing which comprises at least one third thrust pad and temperature measuring elements. The third thrust pad is provided with an oil hole and a mount hole, wherein the oil hole is a blind hole perpendicular to the surface of the third thrust pad, the mount hole is parallel to the surface of the third thrust pad and perpendicularly communicated with the oil hole. The temperature measuring elements are mounted in the mount holes correspondingly, and lubricating oil in the oil holes flows through the temperature measuring elements. As a direct temperature measuring mode is utilized, temperature sensors are in contact with lubricating oil in oil film of a sliding bearing so that temperature of lubricating oil of the sliding bearing made of a polymer material can be measured directly, and further the temperature sensors can reflect change of temperature of the lubricating oil in real time when running condition of the bearing worsens, thereby providing monitoring on instant running states of the bearing and achieving protection of the thrust sliding bearing.

Description

technical field [0001] The invention relates to a polymer thrust bearing, which belongs to the field of bearings, especially the field of new material bearings. Background technique [0002] With the development of industry, the load and speed of ordinary machinery have also increased. High-speed and heavy-duty equipment and components have higher and higher requirements for bearings. Traditional Babbitt bearings are no longer suitable for development. Radial bearings and thrust bearings made of polymer materials (modified PTFE or PEEK) are more expensive than traditional bearings. Babbitt alloy bearings have better wear resistance, higher load capacity (10Mpa), allow operation under very thin film thickness, have higher fatigue strength and excellent electrical insulation performance. This kind of bearing is not only suitable for oil lubricated conditions but also suitable for other low viscosity fluids lubricated conditions, such as water. The thermal conductivity of Bab...
