Problems solved by technology

Relying on traditional manual or semi-automatic operation methods cannot meet the needs of the development of science and technology today. In the precision machining process of machine tools such as turning, milling, and grinding, the precision of the spindle rotation and the degree of wear of the spindle determine the machining accuracy of the parts.
The main shaft of ordinary machine tool equipment is mainly supported by bearings, and its initial precision is not high. As the processing time increases, the mechanical friction and wear are quite serious, the precision of the main shaft rotation becomes worse, and the precision machining accuracy of parts is far below to request

Abstract

The invention relates to the technical field of precision machines, in particular to a hemispherical type gas static pressure shaft system and precision equipment. The hemispherical type gas static pressure shaft system comprises a main shaft, a bearing, a motor and a shaft sleeve, wherein the main shaft and the shaft sleeve are connected through the bearing; the bearing comprises a bushing and abearing bush; the shaft sleeve, the bearing bush, the bushing and the main shaft are sequentially connected in a sleeved mode, the bushing is fixedly connected with the main shaft, the bearing bush isfixedly connected with the shaft sleeve, and the bearing bush is made of porous breathable materials; and an air film air supply hole communicating with the bearing bush is formed in the shaft sleeve, so that gas enters the bearing bush through the gas film gas supply hole and forms a static pressure gas film between the bearing bush and the bush, and the bushing is arranged in the bearing bush in a suspended mode; and the motor is arranged in the shaft sleeve, the rotor of the motor is arranged on the main shaft in a sleeved mode, and the stator of the motor is arranged between the rotor andthe shaft sleeve. The precision equipment comprises the hemispherical type gas static pressure shaft system. The hemispherical type gas static pressure shaft system and the precision equipment are provided, so that the rotation stability and precision of the main shaft are improved.

Description

technical field [0001] The invention relates to the technical field of precision machinery, in particular to a hemispherical gas static pressure shaft system and precision equipment. Background technique [0002] With the development of science and technology, the demand for various machine tool equipment is increasing, and the precision requirements for machine tool equipment are getting higher and higher. Relying on traditional manual or semi-automatic operation methods cannot meet the needs of the development of science and technology today. In the precision machining process of machine tools such as turning, milling, and grinding, the precision of the spindle rotation and the degree of wear of the spindle determine the machining accuracy of the parts. . The main shaft of ordinary machine tool equipment is mainly supported by bearings, and its initial precision is not high. As the processing time increases, the mechanical friction and wear are quite serious, the precisio...
