Abstract
The invention discloses a scroll compressor, and relates to the technical field of compressor manufacturing. The scroll compressor comprises an eccentric shaft and a joint balancing weight, the eccentric shaft is provided with a locating block and a driving shaft arranged at one end of the locating block, and a limiting groove is formed in the driving shaft. The joint balancing weight is provided with a joint and a balancing weight arranged at one end of the joint in a sleeved mode. The balancing weight is arranged on the driving shaft through the joint in a sleeved mode, and the balancing weight abuts against the end face of the locating block. The driving shaft is provided with a limiting check ring at the other end of the joint, and the limiting check ring is arranged in the limiting groove. A gasket is arranged between the limiting check ring and the end face of the joint, and the balancing weight is connected with the locating block. Compared with the prior art, the scroll compressor can solve the problems that a dynamic scroll plate and a static scroll plate are incompletely meshed and vibration is large due to the fact that a needle bearing arranged on the joint balancing weight of an existing scroll compressor is prone to being abraded.
Description
Technical field
The present invention relates to the Compressor Manufacturing technical field, especially a kind of scroll compressor with joint balance piece.
Background technique
At present, scroll compressor more and more generally is applied; A kind of electric scroll compressor is arranged, this scroll compressor includes the movable orbiting scroll of engagement rotation of working in coordination, quiet whirlpool dish, be fixed on the eccentric shaft on casing and be provided with the joint balance piece on described eccentric shaft by bearing, described eccentric shaft has positioning block and is located at the live axle of described positioning block one end, and described live axle is provided with restraining groove; Described joint balance piece has joint and is sleeved on the equilibrium block of described joint one end; Described equilibrium block is contained on described live axle by described joint sleeve, and the end face of described equilibrium block and described positioning block connects; The other end of described live axle in described joint is provided with spacing back-up ring, and described spacing back-up ring is contained in described restraining groove; Be provided with pad between the end face in described spacing back-up ring and described joint; Described eccentric shaft is inserted on the center hole of movable orbiting scroll one end by the needle bearing be sleeved on described joint.There are the following problems in the running to have the scroll compressor of this joint balance piece eccentric shaft: because the joint of joint balance piece is that spacing back-up ring and pad by being installed on the eccentric shaft limited ring groove carries out axial limiting, accumulated error due to accuracy of manufacturing and installation, the axial clearance of part is large, the eccentric shaft axial float of joint balance piece when rotated is large, cause being contained in the needle bearing serious wear on joint, cause moving, the fixed scroll engagement not exclusively, vibrations are large, the defect such as die-off working life, after scroll compressor work a period of time, need be changed needle bearing, increase user cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of scroll compressor, it is incomplete because of the needle bearing dynamic and static scroll engagement caused easy to wear be contained on the joint balance piece that it can solve existing scroll compressor, shake large problem, the working life of raising degree scroll compressor.
The technological scheme that technical solution problem of the present invention adopts is: this scroll compressor includes eccentric shaft and joint balance piece, and described eccentric shaft has positioning block and is located at the live axle of described positioning block one end; Described joint balance piece has joint and is sleeved on the equilibrium block of described joint one end; Described equilibrium block is contained on described live axle by described joint sleeve, and the end face of described equilibrium block and described positioning block connects; Described live axle is inserted on the center hole of movable orbiting scroll one end by the needle bearing be sleeved on described joint, it is characterized in that: described equilibrium block is connected with described positioning block.
In above-mentioned scroll compressor technological scheme, technological scheme can also be more specifically: described equilibrium block is connected with described positioning block by rivet.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect had is: due to the joint balance piece, by its joint sleeve, be contained on the live axle of live axle, and the equilibrium block of joint balance piece is fixed on the positioning block of eccentric shaft by rivet, when rotated, the joint balance piece can not produce axial float at eccentric shaft to eccentric shaft, makes dynamic and static scroll engagement fully, improve scroll compressor traveling comfort and working life, reduce user cost.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the partial enlarged drawing at Figure 1A place.
Fig. 3 is the structural representation of the eccentric shaft that the joint balance piece is housed of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Scroll compressor as depicted in figs. 1 and 2 includes eccentric shaft 3 and joint balance piece 1, and eccentric shaft 3 has positioning block 3-1 and is located at the live axle 3-2 of positioning block 3-1 mono-end, on live axle 3-2, has restraining groove; Joint balance piece 1 has joint 1-1 and is sleeved on the equilibrium block 1-2 of joint 1-1 mono-end, between joint 1-1 and equilibrium block 1-2, locating stud is housed; The live axle 3-2 that equilibrium block 1-2 is sleeved on eccentric shaft 3 by joint 1-1 is upper, and the end face of equilibrium block 1-2 and positioning block 3-1 connects; Live axle 3-2 is set with spacing back-up ring 7 at the other end of joint 1-1, and spacing back-up ring 7 is installed in the restraining groove of live axle 3-2, between the end face of spacing back-up ring 7 and joint 1-1, is set with pad 6; Live axle 3-2 is inserted on the center hole of movable orbiting scroll one end by the needle bearing 4 be sleeved on the 1-1 of joint; The equilibrium block 1-2 of joint balance piece 1 is connected with the positioning block 3-1 of eccentric shaft 3, and the equilibrium block 1-2 of the present embodiment is connected with positioning block 3-1 by rivet 2.
In other embodiments, equilibrium block 1-2 also can be connected with positioning block 3-1 by bolt or screw.
Eccentric shaft 3 when rotated, because the play of joint balance piece 1 at axial direction is defined, can not produce axial float on eccentric shaft 3, has improved the scroll compressor traveling comfort, has reduced use and maintenance cost.
Claims (2)
1. a scroll compressor, include eccentric shaft (3) and joint balance piece (1), and described eccentric shaft (3) has positioning block (3-1) and is located at the live axle (3-2) of described positioning block (3-1) end; Described joint balance piece (1) has joint (1-1) and is sleeved on the equilibrium block (1-2) of described joint (1-1) end; It is upper that described equilibrium block (1-2) is sleeved on described live axle (3-2) by described joint (1-1), and described equilibrium block (1-2) connects with the end face of described positioning block (3-1); Described live axle (3-2) is inserted on the center hole of movable orbiting scroll one end by the needle bearing (4) be sleeved on described joint (1-1), it is characterized in that: described equilibrium block (1-2) is connected with described positioning block (3-1).
