Problems solved by technology

[0002] The vane air motor is a power device widely used in various pneumatic tools and pneumatic machinery. The existing air motors, such as figure 1 , 2 As shown in , it includes a main body 11 and a cylinder lower seat 12 installed in the main body 11, a cylinder 13, a vane 14, a pneumatic rotor 15 and an upper cylinder seat 16, and the lower seat 12 of the cylinder and the upper seat 16 of the cylinder are fixed on the cylinder 13 The two ends of the two ends, the pneumatic rotor 15 is placed in it, the pneumatic rotor 15 is provided with a blade groove 151 for inserting the blade 14, and the cylinder lower seat 12 and the cylinder upper seat 16 are respectively provided with two bearings, so The inner circumference of the bearing 17 is concentric with the outer circumference of the lower seat 12 or the upper seat 16. In order to leave an air gap 18 for gas circulation between the pneumatic rotor 15 and the cylinder, the inner circumference of the cylinder 13 and the outer circumference The circumference is an eccentric structure, which leads to unequal thickness of the cylinder wall, which not only brings difficulty to production and processing, but also makes the volume and weight of the entire air motor larger, and therefore makes the air tool equipment using this motor relatively heavy

Embodiment Construction

[0019] Such as image 3 , 4 , shown in 6, is a kind of preferred embodiment of the present invention, comprises main body 21 and the cylinder lower seat 22, cylinder 23, blade 24, pneumatic rotor 25 and cylinder upper seat 26 that are installed in main body 21, and described cylinder lower seat 22 and the cylinder upper seat 26 are fixed at both ends of the cylinder 23, the pneumatic rotor 25 is placed therein, the pneumatic rotor 25 is provided with blade grooves 251 for inserting the blades 24, the cylinder lower seat 22 and Two bearings 27 are respectively arranged in the cylinder upper seat 26 for fixing the rotor shaft 252 of the pneumatic rotor 25 .

[0020] The cylinder 23 is as Figure 5 As shown in , the outer circumference is concentric with the inner circumference, so that the wall thickness of the entire cylinder wall is the same. In order to ensure that there is enough air gap between the cylinder and the pneumatic rotor, the inner circumference of the bearing o...

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 willbe more agile and convenient.
