Description
Technical field
The utility model belongs to scroll machine field, and particularly, the utility model relates to used in a kind of scroll machine
Cross slip-ring and screw compressor with the cross slip-ring.
Background technique
Scroll machine can be made into scroll expander, screw compressor, vortex engine, vortex pump etc..Wherein scroll compression
Machine could also say that a kind of positive displacement compressor, this screw compressor become increasingly popular dynamic as refrigeration, empty tempered air
In the application such as power.
In general, screw compressor is mainly by movable orbiting scroll, fixed scroll, cross slip-ring, bracket, crankshaft, motor, sealing shell etc.
It constitutes.Swirling device in screw compressor includes two similar scrollworks of shape, each scrollwork is mounted on one individually
On end plate, to limit a scroll.Two scrolls cooperate together, and wherein orbiter is with respect to fixed scroll bias
And rotate the opposed installation of 180 degree.Motor band dynamic crankshaft in screw compressor makes orbiter relative to fixed scroll along rail
Road operation, then forms a series of crescent-shaped spaces between orbiter and the scrollwork of fixed scroll.In orbiter along rail
During road is run, constantly to center, the volume of crescent-shaped space is also subtracting the crescent-shaped space of outer most edge while mobile
It is small, so that the gas volume in the space be made to reduce pressure rise, it is connected to until with central exhaust port, thus by compressed gas
Compressor is discharged in body.
The anti-rotation mechanism of screw compressor be meet orbiter around fixed scroll center revolve while, with to prevent
Stop scroll plate rotation.It prevents orbiter from can take many forms with respect to the shaft coupling of fixed scroll rotation, but generally comprises
Two pairs of keys stretched out from annular element.A pair of keys cooperates in the slot of orbiter, slot of second pair of key cooperation in fixed scroll
It is interior.Although spinning motion of the orbiter relative to fixed scroll can be effectively prevented in the Oldham's coupling of this four keys of band,
But this Oldham's coupling will appear many problems during the work time.
Due to the presence of this four keys, Oldham's coupling will receive the effect of torsional moment in the course of work, to make ten
Couplet joint torsional deflection makes the contact area of key reduce the abrasion for accelerating key surface in this way.As a result lead to screw compressor
Noise and vibration increase, the reduced service life of compressor.Meanwhile just because of the presence of this four keys, Oldham's coupling
The impact several times between orbiter end plate and fixed scroll end plate are easy in the course of work, periodic tilt and vibration is issued and makes an uproar
Sound.This not only shortens the service life of compressor, also constantly issues nuisance vibration and noise.
Utility model content
The purpose of this utility model is to provide one kind at least can partially solve above-mentioned technical problem cross slip-ring and

In order to achieve the above purpose, the utility model provides a kind of cross slip-ring, to keep orbiter in song
Planar circumferential movement is done under the drive of axis in fixed scroll, cross slip-ring is cyclic structure, thrust surface and ten on cross slip-ring
Thrust surface is parallel to each other under word slip ring.The cross slip-ring of the utility model solves to be easily caused present in existing cross slip-ring
It is vibrated in scroll machine, especially screw compressor operational process, the problem that noise and service life are short.
Further, on cross slip-ring thrust surface be equipped on first guide chute and with first on guide chute with always
Guide chute on the second of line, while thrust surface is equipped with the first lower guide chute and exists with the first lower guide chute under cross slip-ring
Collinear second lower guide chute, under the straight line and first on described first on guide chute and second where guide chute
Straight line where guide chute and the second lower guide chute is vertical.
Further, on first on guide chute and second guide chute respectively with the first guide post of fixed scroll and quiet whirlpool
The fitting sliding of the second guide post of capstan；First lower guide chute and the second lower guide chute respectively with the first guide post of orbiter
It is bonded and slides with the second guide post of orbiter.
Further, thrust surface is bonded sliding with fixed scroll thrust surface on cross slip-ring, under cross slip-ring thrust surface with
The fitting sliding of bracket thrust surface.
The utility model also provides a kind of screw compressor, including above-mentioned cross slip-ring, fixed scroll, orbiter, branch
Frame, bearing, crankshaft, rotor, motor stator, middle casing, oil separating plate, lower casing；Fixed scroll is fixed in middle casing
On bracket；Orbiter is cooperated by cross slip-ring and fixed scroll, and orbiter and the cooperation of bracket thrust surface are slided；It is bent
The bearing and orbiter that axis is passed through in bracket cooperate, and the circular-rotation of crankshaft makes whirlpool by the effect of cross slip-ring
Capstan does planar circumferential movement.
