Abstract

The invention discloses a distribution type multi-throttling-region gas static pressure thrust bearing, which comprises a bearing body, wherein the bearing body has a cylindrical shape, a cylindricalgas supply chamber is arranged in the bearing body, a plurality of gas supply threaded holes communicated to the gas supply chamber are uniformly and circumferentially arranged on the gas supply chamber, the gas supply chamber is communicated to a throttling device, the center position of the throttling device is a main throttling region communicated to the gas supply chamber, a plurality of auxiliary throttling regions communicated to the gas supply chamber are uniformly and circumferentially arranged on the main throttling region, and auxiliary throttling region slit throttling grooves are arranged between the two circumferentially adjacent auxiliary throttling regions. According to the present invention, the bearing can be adapted to different working conditions by selecting the reasonable structure parameters; and the distribution type multi-throttling-region gas static pressure thrust bearing has advantages of strong bearing capacity, good structure stability, strong anti-disturbance and recovery ability and broad market prospects, and is suitable for rotating working conditions.

Description

technical field [0001] The invention belongs to the technical field of bearing design, and in particular relates to a distributed multi-section gas static pressure thrust bearing for providing axial thrust. Background technique [0002] With the rapid development of high-precision fields such as ultra-precision measurement and aerospace, the requirements for mechanical manufacturing and machining accuracy continue to increase, and gas bearings with good precision adaptability have been widely used. For gas bearings, due to the small gas viscosity and elastic modulus, how to improve the gas film stiffness and running stability, so that the bearing can run safely, reliably and smoothly within the scope of engineering requirements has become an important issue. The static pressure bearing mainly relies on the static pressure throttle to realize the system function. At present, the common throttling methods used in the gas static pressure bearing include small hole throttling, a...
