Description
Technical field
The present invention relates to a kind of overlay coating method of scroll compressor partition ring, belong to scroll compressor material skill
Art field.
Background technology
Usual scroll compressor, Moving plate and quiet disk relatively rotate during to prevent compressor operating, in Moving plate and machine
A partition ring is devised between frame, Moving plate is done planar movement in motion, and can not be rotated.So Moving plate and quiet disk
Corresponding vortex piece can form several closed regions, these closed areas can be with the rotation of compressor crank shaft, volume
Change, reach air-breathing and the purpose of compression.But during compressor operating, the keyway of Moving plate and the convex key of partition ring and
The keyway of frame and another pair convex key of partition ring can all rub, and add the energy consumption of compressor.With to saving and dropping
Consumption is required to improve constantly, and higher and higher requirement is proposed to the Energy Efficiency Ratio of compressor.To improve the Energy Efficiency Ratio of scroll compressor,
The keyway of Moving plate and the friction of the convex key of partition ring and another pair convex key of the keyway of frame and partition ring are reduced, reduces energy
Consumption.The service life of partition ring is improved by being improved to cross ring surface.Such as Chinese patent application (publication number：
CN01515798A a kind of manufacture method of scroll compressor partition ring) is disclosed, by being modified to the surface of partition ring
Processing, it is different from the material of wherein described fixed component and orbiting scroll member surface to form material on the surface of partition ring
Modify layer.It is gluing so as to avoid the part of boundary lubrication condition from occurring, so as to improve the branch of orbiting scroll member and partition ring
The service life in support structure portion, but it not can solve partition ring and the problem of wear resistance is excessive in itself be present.
The content of the invention
The present invention is directed to above problems of the prior art, there is provided a kind of scroll compressor partition ring and its surface
Method of coating, solve the problems, such as it is how to realize that the coefficient of friction and can reduced when partition ring works enough ensures the effect of required precision
Fruit.
The purpose of the present invention technical scheme is that, a kind of scroll compressor cross ring surface
Method of coating, this method comprise the following steps：
A, aluminium alloy is chosen as corresponding material, according to the size and machining of scroll compressor partition ring
Tolerance, by being machined into the scroll compressor partition ring semi-finished product with convex key；

Then, solidified, baking processing, obtain the scroll compressor partition ring finished product for making convex key be coated with Teflon coating.
The method of coating of scroll compressor cross ring surface of the present invention, the structure of the scroll compressor partition ring are
A kind of conventional structure in this area, scroll compressor has clearly been mentioned to as Chinese patent application (CN01515798A) also has
Partition ring, it is of course also possible to be other conventional scroll compressor partition rings, but due to existing scroll compressor
Larger coefficient of friction mostly be present in the convex key of partition ring, so as to will increase in scroll compressor structure the keyway of Moving plate with
The friction of the convex key of partition ring and another pair convex key of the keyway of frame and partition ring, can influence the raising of energy consumption, to understand
The certainly problem, the present inventor are had found by the surface of scroll compressor partition ring convex key by substantial amounts of work and research
Increase the coating of low-friction coefficient, i.e., by can effectively reduce coefficient of friction in its convex key overlay coating Teflon coating,
Also it is equivalent to add the coating of one layer of low-friction coefficient in cross ring surface, improves observable index；Vortex can also be improved
The antifriction performance of compressor partition ring, so as to improve the service life of scroll compressor partition ring.But on the other hand, by
Higher in requirement of the scroll compressor partition ring to precision in itself, in order to ensure required precision simultaneously, the present invention passes through
