Abstract

The invention discloses a pneumatic rotation device. The device comprises a base, a rotation drive and an air flotation support, wherein the rotation drive and the air flotation support are arranged in the base; the rotation drive comprises a rotation shaft and a drive wheel arranged on the rotation shaft; and the rotation shaft is arranged in the base through the air flotation support, a drive sink hole for driving the drive wheel to rotate in a double-direction manner is formed in the end face of the drive wheel, an air way is formed in the base and comprises an air flotation air way acting on the air flotation support and a drive air way acting on the drive sinking hole, the rotation drive and the air flotation support commonly use the same air source, and the air flotation air way and the drive air way are communicated. The pneumatic rotation device has the beneficial effects of being long in service life, high in rotation speed and small in friction resistance.

Description

technical field [0001] The invention relates to the technical field of mechanical rotary devices, in particular to a pneumatic rotary device driven by compressed gas. Background technique [0002] Mechanical rotary motion, control and measurement technology are used in various industries such as printing, textile, packaging, electronic assembly line, mining, aviation, aerospace, medical treatment, and military industry. Most equipment uses motors for rotary indexing and bearings for rotary support. [0003] The pneumatic rotary device has higher speed, high machining accuracy and high reliability. The existing pneumatic rotary device includes vane type and piston type. The vane type can realize bidirectional rotation, but the service life of this type of vane drive is generally very short. The existing two-way rotary air motor should not rotate higher than 1 / 2 of the no-load speed of the motor during normal use, and the no-load rotation time should not be too long. After a l...
