Abstract
The utility model discloses a support for scroll compressor, include: the friction disc comprises a movable scroll and a friction disc arranged at the lower end of the movable scroll, wherein the lower end surface of the friction disc is provided with a ball groove, and balls are arranged in the ball groove. And the support plate is arranged at the lower end of the friction plate, a plurality of ball rotating grooves are formed in the upper end face of the support plate, the upper parts of the balls are arranged in the ball rotating grooves, the lower parts of the balls are arranged in the ball rotating grooves, and a gap is reserved between the friction plate and the support plate. The support for the scroll compressor is simple in structure, convenient to machine and stable and reliable in operation. When the movable scroll plate drives the friction plate to rotate, the balls make circular motion in the ball rotating grooves on the support plate, so that sliding friction is converted into rolling friction, resistance is reduced, and the service life of the scroll compressor is prolonged.
Description
Technical Field
The utility model relates to a scroll compressor technical field especially relates to a support for scroll compressor.
Background
The movable scroll and the bracket of the existing scroll compressor are usually jointed by an crosshead coupling. Currently, the general form of oldham coupling comprises two pairs of keys distributed crosswise protruding from the ring structure of the oldham coupling. The first pair of oppositely arranged keys are matched in the groove of the movable scroll plate, and the second pair of oppositely arranged keys are matched in the groove of the bracket plate. However, the above-mentioned oldham coupling is subject to a torsional moment due to the keys disposed in an oldham manner during the operation of the scroll compressor, and the oldham coupling is twisted and deformed, and is easily damaged. The torsional deformation causes a change in the contact area of the key with the friction surface between the orbiting scroll and the spider, resulting in a large frictional loss.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects existing in the prior art, the utility model provides a support for scroll compressor.
The technical scheme of the utility model is realized like this:
a bracket for a scroll compressor, comprising:
a movable scroll;
the friction disc is arranged at the lower end of the movable scroll plate, a ball groove is formed in the lower end surface of the friction disc, and balls are arranged in the ball groove;
and the support plate is arranged at the lower end of the friction plate, a plurality of ball rotating grooves are embedded in the upper end surface of the support plate, the upper parts of the balls are arranged in the ball rotating grooves, the lower parts of the balls are arranged in the ball rotating grooves, and a gap is reserved between the friction plate and the support plate.
In the bracket for a scroll compressor of the present invention, the ball rolling groove has a positioning portion in the middle thereof.
In the bracket for a scroll compressor of the present invention, the height of the gap is 1-2 mm.
Implement the utility model discloses a this kind of a support for scroll compressor has following beneficial effect: the support for the scroll compressor is simple in structure, convenient to machine and stable and reliable in operation. When the movable scroll plate drives the friction plate to rotate, the balls make circular motion in the ball rotating grooves on the support plate, so that sliding friction is converted into rolling friction, resistance is reduced, and the service life of the scroll compressor is prolonged. The torque generated by the matching between two pairs of keys and the sliding groove which are arranged in a cross shape in the operation process of the prior scroll compressor is eliminated, so that the whole structure is more reliable and stable.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 5, the bracket for a scroll compressor of the present invention is characterized by comprising:
the orbiting scroll 10.
And a friction disc 11 mounted at the lower end of the movable scroll 10. The friction disc 11 is provided with ball grooves 12 on the lower end surface thereof, and the ball grooves 12 are provided with balls 13 therein. The balls 13 may be kept rollable in the ball grooves 12. And a support plate 14 arranged at the lower end of the friction plate 11, wherein a plurality of ball rotating grooves 15 are embedded in the upper end surface of the support plate 14, the upper parts of the balls 13 are arranged in the ball rotating grooves 12, the lower parts of the balls are arranged in the ball rotating grooves 15, and a gap is reserved between the friction plate 11 and the support plate 14. The height of the gap is 1-2 mm. The clearance is to ensure a distance between the friction disc 11 and the support plate 14, and to prevent sliding friction between the friction disc 11 and the support plate 14.
And a positioning part 16 is provided in the middle of the ball rolling groove 15. The balls 13 can make a circular motion along the positioning portions 16 while the balls 13 rotate in the ball rotation grooves 15.
The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
