Background technique
In the existing oblique tray type compressor, be used to connect the semicircle steel ball of piston and swash plate, its friction surface directly contacts with the swash plate plane, Toyota of Co., Ltd. as Japan makes 1241245A number disclosed type of the patent specification CN of institute automatically, as shown in Figure 3, comprise front and rear cylinder 1,6, swash plate 4, semicircle steel ball 2,5, piston 7 and transmission shaft 5; The sliding contact surface 41,42 of described swash plate 4 and the friction surface of semicircle steel ball 2,5 form sliding contact, utilize transfer method to apply solid lubricant films on the friction surface of this swash plate 4 and semicircle steel ball 2,5, this solid lubricant comprises at least a lubriation material that selects in molybdenum disulfide, tungsten disulfide and the graphite.Therefore the service behaviour of film and the rate of film build of oiling agent have been improved.Yet be used to connect the semicircle steel ball 2,5 of this swash plate 4 and piston 7; its surface directly contacts with swash plate sliding contact surface 41,42; though swash plate sliding contact surface 41,42 wear-resistant coatings protection; but this coating that is in operation can produce irregular wear in swash plate sliding contact surface 41,42 and the planar slide of semicircle steel ball; thereby influence its sliding capability, and reduce its operating life.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, and the exercise performance of the connection set of a kind of piston that had both had a good compression machine and swash plate is provided, and can improve the piston connection device of the oblique tray type compressor of its operating life again.
The objective of the invention is that the connection set of piston by a kind of oblique tray type compressor with following structure is provided and swash plate realizes, this device comprises piston, two semicircle steel balls, swash plates and the cylinder that matches with described piston, described two semicircle steel balls are in two hemisphere face grooves of the inner chamber both sides that are embedded in piston that are parallel to each other, described swash plate is embedded between the working plane that is parallel to each other of two semicircle steel balls, and can slide betwixt; Described swash plate has two inclined working that are parallel to each other, at described two semicircle steel balls a working plane is arranged respectively, on the working plane of described two semicircle steel balls, respectively be provided with an annular groove, in described annular groove, inlay a polytetrafluoroethylene wear-resistant block, described polytetrafluoroethylene wear-resistant block directly contacts with the inclined working of swash plate, and make this polytetrafluoroethylene wear-resistant block directly and the inclined working friction slip of swash plate, described polytetrafluoroethylene is a polymer composite, has good anti-wear and wear-resistant performance, it can reduce the fracture ratio of lubricating film between the working plane of the inclined working of swash plate and semicircle steel ball, when it makes slide relative, can stick to the chemical molecular of polytetrafluoroethylene on the inclined working of relative swash plate, form a kind of lubricating film effect, reduce surface friction drag, but also has the shock-absorbing effect, improved the inclined working and the surperficial frictional behavior of semicircle steel ball of swash plate greatly between the two, and can improve the stationarity of piston linear reciprocating motion and reduce its running noises.
One endoporus that forms an angle with the inclined working of swash plate is arranged in the middle of the swash plate, and this endoporus is connecting transmission shaft and is driving swash plate and rotating, and does reciprocating linear motion in cylinder thereby promote piston.
On the working plane of semicircle steel ball, also be provided with a triangle oil groove, in order to store lubricant oil and the inclined working of swash plate and the good lubrication condition between the polytetrafluoroethylene wear-resistant block on the semicircle steel ball are provided.
Described polytetrafluoroethylene wear-resistant block adopts embedding method to be connected with the working plane of described two semicircle steel balls.
Compared with prior art, the invention has the advantages that: 1. the swash plate sliding contact surface of aluminium matter does not need to spray wear resistant coating; 2. when the high-abrasive material of swash plate sliding contact surface and semicircle steel ball rubbed, its friction factor reduced; 3. reduced running noises; 4. high-abrasive material has the shock-absorbing effect, steadily moves in the time of making reciprocating motion of the pistons, and can improve its operating life.
