Abstract
The utility model relates to a pneumatic motor rotor, which belongs to a motor part. The utility model comprises a main bearing, a vane and a rotor cover. The vane base integrates with the same axes center of the main bearing along the portrait direction, and the diameter is larger than the one of the main bearing, vane troughs are equally opened at the column of the vane base along the circle, the vane activity make the vanes cooperate with each other to embed into the vane trough along the portrait direction, the air holes are opened among the vane troughs in the vane base column and are crossly connected with each other along the portrait direction. A suit rotor cover is arranged at the outer circle space of the vane base, the outer wall circle of the rotor cover has the same axes center with the main bearing and the vane base, and the inner wall circle of the rotor cover is eccentric with the main bearing and the axes of the vane base, an air inlet hole is arranged at the side wall of the rotor cover. The utility has the advantages of that: the utility model has a large torque and has great work efficiency, and the service life is long.
Description
Technical field
The utility model belongs to engine part, specially refers to a kind of pneumatic motor rotor.
Background technique
Known notification number is: the CN1329695 axial rotary engine, disclose a kind of engine rotor structure: its blade has flat drum, two tangential slots are arranged on its side surface, the position is relative mutually, the shape that the guiding grooving of rotor has is equivalent at the cross section perpendicular to the diametral plane intra vane of tangential slot direction, and seal element is installed on the side surface of dish portion of blade, and might be along the peripheral unrestricted motion of the dish portion of blade.But, cause its pressure little, inefficiency because its rotor blade lifting surface area is little.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and providing a kind of can increase torque, the pneumatic motor rotor of increasing work efficiency.
Pneumatic motor rotor of the present utility model is to be made of main shaft, blade and rotor cover.Have blade pedestal and main shaft concentric vertically to be integral and diameter greater than the diameter of main shaft, what be uniformly distributed along the circumference on the cylindrical body of blade pedestal vertically has a blade groove, the movable cooperation of blade vertically embeds in the blade groove, and what all vertically connect between each blade groove in blade pedestal cylindrical body has a gas duct.At the circumferential play engage sleeves cartridge rotor cover of blade pedestal, the outer wall circumference of rotor cover and main shaft and blade pedestal are concentric, and it is eccentric that the axis of its inwall circumference and main shaft and blade pedestal is, and on the sidewall of rotor cover inlet hole arranged.
The utility model can have a plurality of blade grooves in actual applications on the cylindrical body of blade pedestal, and the blade of a plurality of pairings is with it embedded in the blade groove; Also Blade Design can be become plane shape or curvecd surface type, make it to match with blade groove.
Further improve as the utility model, all gaps of ring of the inner ring surface of the outer ring surface of blade pedestal and rotor cover are not for radially equidistant.
Pneumatic motor rotor design of the present utility model is reasonable, simple in structure, moment of torsion is big, high working efficiency, long service life.
