Compression chamber is formed, fixed scroll is fixed in frame, orbiter is driven by eccentric shaft and rotated, in order to prevent orbiter rotation
And anti-rotation mechanism is set on orbiter, so that orbiter makees very little around the basic circle center of fixed scroll all the time
The Plane Rotation of radius, limits the rotational trajectory of orbiter, it is ensured that the spiral shell on hurricane band and fixed scroll on orbiter
Rotation band can stable engagement extrusion medium, i.e., some ball holes are uniformly arranged on the back side of orbiter, in the end face of floral disc
Position-arresting disk is set, and position-arresting disk is provided with ball spacing hole, and each ball hole stretches into ball built with a ball, the outer end of ball
In spacing hole, depart from track so as to prevent orbiter certainly, but ball is easily tumbled when installing, and needs frock
Ball is positioned, assembling process is comparatively laborious, had a strong impact on the efficiency of assembling of compression assembly；With ball and ball hole
Between long-term rolling friction, ball surface abrasion and cause radius to reduce so that the track of orbiter changes,
The sealing of compression chamber is reduced, and media collapse efficiency is reduced.
Utility model content
This utility model is easy in order to solve ball in scroll compressor compression assembly assembling process of the prior art
Drop, assemble the low problem of inconvenient, efficiency of assembling, there is provided a kind of high scroll compressor of easy to assembly, efficiency of assembling
Compression assembly structure.
To achieve these goals, this utility model is adopted the following technical scheme that：
A kind of scroll compressor compression assembly structure, including main shaft, the eccentric shaft of spindle nose is located at, described bias
Axle is provided with orbiter, rotates connection, be provided with fixed scroll on the outside of the orbiter between orbiter and eccentric shaft,
Compression chamber is formed between described fixed scroll and orbiter, the side of the fixed scroll is provided with Jie connected with compression chamber
Matter inlet hole, the center of the fixed scroll are provided with the medium connected with compression chamber and are portalled, and described main shaft is provided with floral disc, described
The edge of floral disc is fixedly connected with the edge of fixed scroll, and described floral disc is connected with main axis, and described orbiter exists
Which is provided with some spacing holes being uniformly distributed circumferentially towards the end face of floral disc, and the end face of the floral disc is provided with and spacing hole
One-to-one spacer pin, the diameter of the spacer pin are less than the diameter of spacing hole.Floral disc is connected with fixed scroll, both
Static, main shaft drives eccentric shaft turns, eccentric shaft to drive orbiter to make very little around the basic circle center of fixed scroll all the time
The Plane Rotation of radius, it is spacing with spacer pin due to passing through spacing hole between orbiter and floral disc, therefore orbiter cannot
Rotation, eccentric shaft, spacing hole, spacer pin coordinate the rotational trajectory for limiting orbiter, it is ensured that stable pressure of the compression chamber to medium
Contracting, this kind of structure eliminate ball, assemble convenient, efficiency of assembling and significantly improve.
Preferably, wear ring is provided with described spacing hole, described wear ring is coordinated with spacing interporal lacuna, the limit
Internal diameter of the diameter of position pin less than wear ring.When orbiter is rotated, can there is friction between spacing hole and spacer pin, if do not had
There is wear ring, then the inwall of spacing hole easily weares and teares, have to change whole orbiter after spacing hole inner wall abrasion；Wear ring
The inner wall abrasion of spacing hole can be prevented, while enhancing anti-wear performance, after long-time use, is occurred between wear ring and spacer pin
Abrasion, it is only necessary to change wear ring and spacer pin, change, safeguard very convenient, low cost.
Preferably, the endoporus two ends of the wear ring are equipped with rounded corner, it is equipped with the outside of the two ends of the wear ring
Ramp down angle.Rounded corner energy deburring, prevents the edge scratch spacer pin at wear ring endoporus two ends；Dress of the ramp down angle to wear ring
With playing guide effect so that wear ring loads convenient in spacing hole.
Preferably, described eccentric shaft is provided with eccentrically mounted weight set, between described orbiter and eccentrically mounted weight set
Connected by bearing.
Therefore, this utility model has the high beneficial effect of easy to assembly, efficiency of assembling.
