Abstract
The utility model discloses a compressor ball seat comprising a ball seat body. The two sides of the body are a spherical gliding plane and a planar gliding plane, and multiple oil storage grooves are disposed radially on the planar gliding plane. The utility model is characterized in that, besides the radial oil storage groove, an annular oil storage groove is added and communicated therewith. The utility model has perfect structure, good lubricating effect, and prolonged service life.
Description
Technical field
The utility model relates to a kind of packing ring, especially compressor ball pad.
Background technique
Compressor ball pad is applied to the bidirectional piston Wobble plate type refrigerant compressor, the straight line motion of this compressor piston is to drive swash plate by main shaft to do the swing rotation, promote the ball pad and then promote the piston moving linearly, wherein the ball pad is done relative sliding motion with swash plate, because the ball pad of prior art is an entity structure, lubricant oil is difficult to enter slip plane, during the compressor high speed operation, the ball pad produces wearing and tearing under the load effect, and the metal that weares and teares can be bonded on the surface of contact of swash plate, make the condition of wearing and tearing more become to worsening, quicken the ball pad and damage.Therefore, the applicant proposes the Chinese patent application at sphere slip plane and the radially uniform trapped fuel groove of plane slip plane at this point, the patent No. is 03230728.4 " compressor ball pad ", though it has solved ball pad and the lubricated problem of slip plane, but, because only at radially direct trapped fuel groove, lubrication effect still is undesirable, particularly rub between more violent the planar slip face and swash plate, can't satisfy lubricated needs far away.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and provides a kind of lubrication effect better, the compressor ball pad that structure is more perfect.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of compressor ball pad, comprise the ball pad body, the body bi-side are sphere slip plane and plane slip plane, and planar slip face upper edge is radially distributed with many trapped fuel grooves, it is characterized in that also being provided with on the described planar slip face ring-type trapped fuel groove, this ring-type trapped fuel groove connects with trapped fuel groove radially.
Described ring-type trapped fuel groove is with the uniform 1-2 bar of concentric type.
Described ring-type trapped fuel slot cross-section is shaped as recessed circle or recessed triangle or recessed square or recessed trapezoidal.
Described trapped fuel groove both sides notch is the chamfering shape.
Compared with prior art, the utility model radially increases ring-type trapped fuel groove again on the basis of trapped fuel groove in the glide plane and interpenetrates, thereby obtains better lubrication effect, makes structure more perfect.

Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 7, the utility model compressor ball pad, its structure comprises ball pad body 2, the body both sides are sphere slip plane 1 and plane slip plane 3, planar slip face 3 is provided with radially uniform trapped fuel groove 5 and is the ring-type trapped fuel groove 4 in the center of circle with the center hole, and both cross one another and connect on the planar slip face.Radially the quantity of trapped fuel groove and ring-type trapped fuel groove is looked the customer requirements design.
The trapped fuel slot cross-section is recessed circle, and the both sides notch is chamfering shape.
