Description
Technical field
The utility model is related to Compressor Technology field, specifically a kind of compressor anti-rotation mechanism.
Background technology
Screw compressor is usually by movable orbiting scroll, fixed scroll, anti-rotation mechanism, eccentric shaft, the compositions such as holder.In the course of work
In, eccentric shaft drives movable orbiting scroll movement, movable orbiting scroll vortex to be engaged with fixed scroll vortex, gas is gradually reduced.It is compressing
In the process, it is necessary to prevent movable orbiting scroll from rotating, just can guarantee movable orbiting scroll and fixed scroll correct engagement.Common anti-rotation mechanism cross
Slip ring（Also known as cross coupler）, straight pin, special entity ball bearing, small crankshaft etc..
There are two types of existing straight pin anti-rotation mechanisms：（1）Straight pin is fixed on Moving plate, there is trepanning, cylinder on holder
Pin slides in bracket holes, and the hole on holder is rotated by limiting straight pin to limit movable orbiting scroll.（2）Straight pin is fixed on holder
On, there are trepanning, straight pin to be slided in Moving plate hole on Moving plate, straight pin limits movable orbiting scroll rotation.
Existing special entity ball bearing anti-rotation mechanism is as follows：It is each on movable orbiting scroll and holder that fix an annular fixed
Circle, annular enclose and are provided with a series of holes calmly, and ball is located in hole, is fitted closely with the inner wall in hole.It is fixed by ball limitation annular
Circle rotation, and then limit movable orbiting scroll rotation.
For straight pin anti-rotation mechanism, the bore dia for limiting straight pin is bigger, and hole precision requires relatively high, it is difficult to add
Work.During the work time, straight pin is slided along hole inner wall is moved, and can lead to the abrasion in hole.In order to reduce abrasion, need to movable orbiting scroll
Hole is further processed（Such as：Increase a becket in hole）, increase cost.Straight pin and it is anti-from turn hole or straight pin and
Prevent that frictional dissipation is larger, influences working efficiency from being sliding friction between the becket in turn hole.In addition anti-certainly for straight pin
Rotation mechanism, holder and Moving plate binding face, are sliding friction during the work time, frictional dissipation is larger, influences working efficiency.
For special entity ball bearing anti-rotation mechanism, in order to ensure that ball can work normally, on the fixed circle of annular
Ball-and-socket needs very high dimensional accuracy and positional precision, and leading to annular, circle cost is very high surely, and is very easy to because precision is asked
Topic causes whole compressor to damage.Annular fixed circle will bear anti-rotation power, to prevent annular fixed circle abrasion, be heat-treated
Etc. processes, further increase manufacture difficulty and cost.
Therefore, the utility model mainly for straight pin anti-rotation mechanism and special entity ball bearing anti-rotation mechanism into
Row improves.
