Model utility content
The technical problems to be solved in the utility model overcomes existing defect, a kind of pneumatic vane motor with motion cam circle is provided, by cam ring is put into its rotor, rotor is in stator during state of rest, and blade is sealed as stator inner circle by cam ring top all the time, during rotor motion state, blade pushes away mutual top mutually by motion cam circle, when lowpressure starts or move, blade and stator inner circle is sealed and reaches optimal seal, form work done inner chamber, thus solve the problem.
For achieving the above object, the utility model provides following technological scheme: a kind of pneumatic vane motor with motion cam circle, comprise rotor, be arranged on rotor center and through the rotor shaft of rotor, cam ring and stator, described rotor is provided with the blade groove for installing blade, the through hole that internal diameter is greater than described rotor shaft diameter is provided with in the middle of described cam ring, described cam ring comprises lordosis wheel rim and rear cam ring, described rotor is enclosed within stator, and the diameter of described rotor is less than the inner diameter of stator.
Further, the two ends of described rotor are equipped with the groove matched with cam ring, and the outer diameter of cam ring is less than the diameter of groove.
Further, described lordosis wheel rim is the same with rear cam ring profile, and makes for polyoxymethylene material.
Further, described blade groove is 4, and is evenly distributed on rotor.
Further, described blade is 4, and described blading is in blade groove and have gap with blade groove.
Compared with prior art, the beneficial effects of the utility model are: a kind of pneumatic vane motor with motion cam circle, by cam ring is put into its rotor, rotor is in stator during state of rest, blade is sealed as stator inner circle by cam ring top all the time, during rotor motion state, blade pushes away mutual top mutually by motion cam circle, when lowpressure starts or move, blade and stator inner circle are sealed and reaches optimal seal, form work done inner chamber, compact structure, with low cost, be easy to realize, start air pressure low simultaneously, the surface friction drag of blade is little, the processing of component is relatively simple, easy-maintaining.
