Abstract

The application provides a high-speed driving device; it includes a housing and a driving unit, and the inside of the housing is provided with a communicating accommodating cavity and a channel; the inner wall of the channel is provided with a first annular groove and a second annular groove along the circumference The outer wall of the channel is provided with a first through hole communicating with the first annular groove and a second through hole communicating with the second annular groove, the first through hole and the second through hole are connected with the positive pressure fluid compressor and the second through hole respectively. The negative pressure fluid compressor is connected; the driving unit includes a rotating shaft and a matched stator and rotor; the stator and the rotor are arranged in the accommodating cavity, one end of the rotating shaft is fixedly connected with the rotor, and the other end extends along the channel and protrudes out of the shell body, there is a gap between the inner side wall of the channel and the rotating shaft. In the present application, through the arrangement of the first annular groove and the second annular groove, the positive pressure fluid compressor and the negative pressure fluid compressor can exert radial support force on the rotating shaft to ensure the stable rotation of the rotating shaft.

Description

technical field [0001] The present application relates to the technical field of drive devices, in particular to a high-speed drive device. Background technique [0002] The driving device may be a device that drives the workpiece or the tool to rotate. In order to ensure the high-speed rotation of the rotating shaft and reduce the shaking of the rotating shaft during rotation, in the current technical solution, the rotating shaft is supported by high-pressure gas to reduce the friction of the rotating shaft when rotating, and at the same time reduce the friction of the rotating shaft. Radial wobble during rotation. However, the support of the rotating shaft by a single high-pressure gas cannot satisfy the stable support for the rotating shaft, and it is also impossible to accurately adjust the radial force on the rotating shaft, resulting in radial shaking of the rotating shaft. Contents of the invention [0003] The purpose of the present invention is to provide a high...
