Abstract

The invention provides a pneumatic vane motor with rolling pairs. The pneumatic vane motor mainly comprises a front machine cover, a rear machine cover, a front end cover, a rear end cover, a rotor, a cylinder, a blade, an intake hole, an exhaust hole, a blade tail end rolling pair I and a cylinder interior wall rolling pair II, wherein the blade tail end rolling pair I and the cylinder interior wall rolling pair II are assembled between the tail end of the blade and the inner wall of the cylinder; the sliding friction between the tail end of the blade and the interior wall of the cylinder is converted into rolling friction by rolling of the blade tail end rolling pair I and the cylinder interior wall rolling pair II. The pneumatic vane motor is simple in structure, and small in change on the original motor; sliding friction between the original blade and the interior wall of the cylinder is converted into rolling friction by common rolling action of the blade tail end rolling pair and the cylinder interior wall rolling pair; abrasion between the blade and the interior wall of the cylinder is effectively reduced; the conversion efficiency of the motor is improved; an auxiliary oil mist spray device and an additional coating are not needed; and the cost is saved.

Description

technical field [0001] The invention belongs to the category of pneumatic motors in the technical field of machinery, and in particular relates to a vane type pneumatic motor with a rolling pair. Background technique [0002] The vane air motor is a prime mover with compressed gaseous working fluid as its power source. It is a device that converts pressure energy into mechanical energy by using the expansion of compressed working fluid. It generally consists of a casing, a machine cover, a cylinder, a rotor, blades, Composed of front and rear end covers, bearings, bushings, thrust rings and other parts, a working chamber is formed between the stator and the rotor. After the compressed working fluid enters the working chamber, the pressure can generate torque on the blades to make the rotor rotate and do work. [0003] During the high-speed operation of the vane air motor, the vane and the inner wall of the cylinder will have a large sliding friction, resulting in varying deg...
