Abstract
The invention discloses a slide vane compressor. The slide vane compressor comprises a compressor cylinder, wherein the compressor cylinder is provided with an eccentric rolling piston driven by a rotating shaft; the piston is tangent to the cylindrical surface of the inner wall of the cylinder; the slide vane is arranged between the cylinder body and the piston; the root of the slide vane is positioned in the cylinder body and provided with a spring slot; a spring is arranged between the slide vane and the cylinder body; a transverse groove is arranged at the top of the slide vane; a cylindrical roller pin is arranged in the groove and can roll in the groove; the groove is exposed out of the roller pin; and the roller pin clings to the piston surface by virtue of the elasticity of the spring. The slide vane compressor has the advantages that the slide vane is arranged in the cylinder and is difficultly damaged, rolling friction is formed between the slide vane and the piston, the energy consumption by friction is low, the energy utilization rate is improved, the abrasion loss of the piston is reduced, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of compressor, particularly a kind of sliding-vane compressor.
Background technique
Sliding-vane compressor is also referred to as rotary compressor, and its major component is compression cylinder, and compression cylinder is primarily of cylinder body, rotor (rotating piston or rolling piston) and slide plate composition, and rotor is eccentric in the cylinder to be placed.Be provided with slide plate between rotor and cylinder block, make because of rotor turns the volume of cylinder of slide plate two side change, thus complete the lasting suction of medium and compression.Because sliding-vane compressor structure is simple, efficiency is high, operation and maintenance easy maintenance, work is tranquil, it is little to vibrate, and therefore sliding-vane compressor is widely used.But for sliding friction between the slide plate of existing sliding-vane compressor and rolling piston, frictional force is large, big energy-consuming, piston abrasion loss are fragile greatly, is therefore necessary to be improved.
Summary of the invention
Technical problem to be solved by this invention be overcome prior art above-mentioned deficiency and a kind of sliding-vane compressor is provided, the frictional force of the slide plate in compressor is little, power consumption less, abrasion loss is low.
The present invention's adopted technological scheme that solves the problem is: a kind of sliding-vane compressor, comprise compresser cylinder, it is characterized in that: configure by turning shaft-driven eccentric rolling piston in described compresser cylinder, the inwall cylndrical surface of piston and cylinder is tangent, cylinder block and piston space are equipped with slide plate, the root of slide plate is positioned at cylinder block and has spring groove, between slide plate and cylinder block, spring is housed, the top of slide plate has cross groove, cylindrical needle roller is placed in groove, needle roller can roll in groove, needle roller exposes outside groove, the elastic force of spring makes needle roller be close to piston area.
Above-mentioned groove is U-groove bevel, and U-groove bevel side is provided with spacing closing in, closes up to give prominence to stretch to groove top, and prevent needle roller from coming off from groove, U-groove bevel is more easily processed.
It is two right that above-mentioned closing in can be, and symmetrical is distributed on the side of groove, like this can be spacing better.
Compared with prior art, the invention has the advantages that:
1, slide plate is arranged in cylinder block, is in and does relatively reciprocating motion during compressor operating.
2, arrange rotatable cylindrical needle roller in slide plate groove, needle roller exposes outside groove, makes the friction mode between slide plate and piston be rolling friction, reduces because of the energy consumed that rubs, improves capacity usage ratio and compressor efficiency, reduce piston wear amount.
3, groove side is provided with spacing closing in, can prevent needle roller from coming off from groove upper opening.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is slide vane structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
The structural representation of sliding-vane compressor as shown in Figure l, cylinder 8 is its stator, eccentric configuration rolling piston 7 in cylinder 8, as its rotor, it is driven by rotating shaft 6, piston 7 is tangent with the inwall cylndrical surface of cylinder 8, cylinder block is built with slide plate 1, and as shown in Figure 2, the root of slide plate 1 is positioned at cylinder block and has spring groove 13 structure of slide plate, have spring 3 between slide plate 1 and cylinder 8, the top of slide plate 1 has horizontal U-shaped or arc groove.Place cylindrical needle roller 2 in groove, needle roller 2 can roll in groove, and needle roller 2 exposes outside groove, the elastic force of spring 3 makes needle roller 2 be close to piston 7 cylndrical surface, make to be rolling friction between the two, reduce friction energy loss, crescent-shaped space is divided into air aspiration cavity 4 and compression chamber 5 by slide plate 1.
Slide plate groove side is provided with spacing closing in 12, and closing in 12 is outstanding stretches to groove top, and during assembling, can be inserted by needle roller 2 from one end of groove, the outstanding position of closing in 12 prevents needle roller 2 from coming off from the opening on the top of groove.
Tilt in groove for preventing needle roller 2 or excessively to loosen, it is two right that spacing closing in 12 is arranged to, and symmetrical is distributed on groove side, can certainly be arranged to multipair.
In order to ensure stability and the balance of slide plate 1, spring groove 13 is one or more, and shape can be trapezoidal, square or arc etc., and corresponding spring 3 is also one or more.
Claims (1)
1. sliding-vane compressor, comprise compresser cylinder, it is characterized in that: configure by turning shaft-driven eccentric rolling piston in described compresser cylinder, the inwall cylndrical surface of piston and cylinder is tangent, cylinder block and piston space are equipped with slide plate, the root of slide plate is positioned at cylinder block and has spring groove, between slide plate and cylinder block, spring is housed, the top of slide plate has cross groove, cylindrical needle roller is placed in groove, needle roller can roll in groove, needle roller exposes outside groove, the elastic force of spring makes needle roller be close to piston area, the cross groove that slide plate top is opened is U-shaped or arc groove, described groove side is provided with spacing closing in, close up to give prominence to and stretch to groove top, prevent needle roller from coming off from slot opening, described closing in is two right, symmetrical is distributed on the side of groove, described spring groove has one or more.
