Abstract

The invention relates to a two-way dynamic-static pressure mixture lubrication thrust bearing. Aiming to solve the problems of low accuracy and poor operating stability in an existing high-speed and heavy-load extreme working condition, the invention provides the two-way dynamic-static pressure mixture lubrication thrust bearing. The two-way dynamic-static mixture lubrication thrust bearing comprises a dynamic-static pressure oil pad, a circular machine tool base and a rotary workbench, wherein the rotary workbench is arranged right above the dynamic-static pressure oil pad; the circular machine tool base is arranged under the dynamic-static pressure oil pad; wedges are arranged on the dynamic-static pressure oil pad of the two-way dynamic-static pressure mixture lubrication thrust bearing and are arranged in two inner sides of the circumferential direction of an oil sealing edge. The two-way dynamic-static pressure mixture lubrication thrust bearing is applied to the field of high-speed and heavy-load machine tool workbenches.

Description

technical field [0001] The invention relates to a two-way dynamic and static pressure mixed lubrication thrust bearing. Background technique [0002] With the emergence of high-speed and heavy-duty cutting technology, the actual role of static pressure bearings is becoming more and more obvious. However, the domestic static pressure bearing technology is still far from perfect, and static pressure bearings often have boundary lubrication and tribological failures. Lubrication failures Not only will it reduce work efficiency, processing accuracy, poor operation stability, increase energy consumption, and increase material wear, but also cause parts damage, machine damage, and even casualties, bringing economic losses to the country. In order to make full use of the dynamic pressure effect, improve the supporting capacity of the static pressure, and ensure its high-precision and stable operation, start with the mixed lubrication of the dynamic and static pressure, change the e...
