Abstract

The invention discloses a braking integrated pneumatic motor, belonging to the technical field of pneumatic motors. The pneumatic motor comprises a stator installed in a shell and a rotor eccentrically arranged in the stator, wherein blade grooves are arranged on the rotor; and blades are arranged in the blade grooves in a matching manner and can move in the radial direction. The pneumatic motor is characterized in that an output shaft of the rotor is supported on a front end cover of the shell via bearings 1; the front end of the output shaft extends out of the front end cover; shaft sleevesare arranged at the front end of the output shaft; a section of outer splines are arranged on the output shaft between the front end cover and the shaft sleeves; braking bases are arranged on the outer splines in a matching manner; friction plates are arranged at the rear ends of the braking bases; wedge-shaped grooves are arranged at the front end of the front end cover and are matched with the friction plates; and resetting devices are arranged between the shaft sleeves and the braking bases. The pneumatic motor is sensitive to respond and has good braking effect, high safety property, highlifting speed and compact structure.

Description

technical field [0001] The invention discloses an air motor with integrated braking, which belongs to the technical field of air motors. Background technique [0002] The air motor is an important part of the air hoist device. It converts the pressure of compressed air into rotational mechanical energy, and then drives the lifting mechanism of the air hoist to perform lifting movements. However, the existing air motors generally have the problems of slow response and poor braking effect, which bring certain safety hazards to the hoisting work. At the same time, the existing air motor still has the defects of complex structure, large size and high production cost. Contents of the invention [0003] In order to solve the above problems, the present invention provides a brake-integrated air motor with good braking effect and high safety performance. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: [0005] An air mo...
