Example Embodiment

[0021] As shown in Figures 3, 4 and 6, it is a preferred embodiment of the present invention, comprising a main body 21 and a lower cylinder seat 22, a cylinder 23, a vane 24, a pneumatic rotor 25 and an upper cylinder seat 26 installed in the main body 21, The lower cylinder seat 22 and the upper cylinder seat 26 are fixed on both ends of the cylinder 23, the pneumatic rotor 25 is placed therein, and the pneumatic rotor 25 is provided with a blade groove 251 for inserting the blade 24. The lower cylinder seat 22 and the upper cylinder seat 26 are respectively provided with two bearings 27 for fixing the rotor shaft 252 of the pneumatic rotor 25 .

[0022] As shown in FIG. 5, the outer circumference of the cylinder 23 is concentric with the inner circumference, so that the wall thickness of the entire cylinder wall is the same. In order to ensure sufficient air gap between the cylinder and the pneumatic rotor, the cylinder lower seat 22 The inner circumference of the upper bea...

Abstract

A pneumatic motor is disclosed, the cylinder structure of which is changed to make the bearing at upper seat and the bearing at lower seat eccentric respectively to the internal circumference of the cylinder and make the internal circumference and the external circumference of the cylinder in concentric structure, so that under the precondition of not changing the volume of the cylinder internal chamber, the weight and volume of the whole pneumatic motor are all reduced, its appearance is legerity, for same appearance specification it has higher torque, tools adopting the pneumatic motor will be more agile and convenient.

Description
