Specific embodiment
The utility model embodiment solves in the prior art that structure is complicated by providing a kind of scroll machine eccentric stiffener
The technical issues of, realize the technical effect for reducing requirement on machining accuracy and manufacturing cost.
The technical scheme in the embodiment of the utility model is to solve the above problems, general thought is as follows:
Counterweight is arranged on crankshaft, axle sleeve is set in the protruding shaft of crankshaft, and primitive axis set weight set zoarium is resolved into and is matched
Two parts of weight and axle sleeve, simplify structure, not only reduce requirement on machining accuracy, and also reduce manufacturing cost.
Above-mentioned technical proposal in order to better understand, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
Scroll machine eccentric stiffener provided by the embodiment of the utility model, comprising: crankshaft, counterweight and axle sleeve；In crankshaft
First end has protruding shaft；Counterweight is arranged on crankshaft, forms crankshaft body；Axle sleeve is set in protruding shaft；Axle sleeve can be rotated around protruding shaft.
There is gap between crankshaft body and axle sleeve, crankshaft body limits the rotating range of axle sleeve.
In the present embodiment, protruding shaft can be integrally formed with crankshaft, can also be fixed on the first end of crankshaft.
The utility model embodiment provides two kinds of specific structures of crankshaft body, referring to Fig. 1 and Fig. 2, crankshaft body
The first specific structure are as follows: have boss in the first end of crankshaft 1；There is gap between boss and axle sleeve 3, to limit the rotation of axle sleeve 3
Turn range.
Specifically, referring to Fig. 3 and Fig. 4, the outer wall of boss opposite direction axle sleeve 3 is boss plane 12；The side wall of axle sleeve 3 has axle sleeve
Plane 31；There is gap between boss plane 12 and axle sleeve plane 31.
In the present embodiment, boss plane 12 is parallel or not parallel with axle sleeve plane 31.
What needs to be explained here is that can be plane with one, the other is bent in boss plane 12 and axle sleeve plane 31
