Abstract

The invention discloses a scroll compressor, which belongs to the technical field of manufacturing of compressors. The scroll compressor comprises a driving shaft which is provided with an eccentric shaft part and a main shaft part, wherein a joint balancing piece sleeves the eccentric shaft part, the eccentric shaft part is provided with a driving surface abutting against the inner hole of the joint balancing piece, the driving surface and the surface where a line between the center of the eccentric shaft part and the center of the main shaft part lies are arranged to form an acute angle, and the included angle is in a range of 15 to 21 DEG. Compared with the prior art, the scroll compressor provided by the invention can overcome the problems of uneven stress on the driving surface of the driving shaft of the scroll compressor and great break-out torque.

Description

Scroll compressor
Technical field
The present invention relates to Compressor Manufacturing technical field, the scroll compressor that especially a kind of drive surface of its eccentric drive shaft is inclined-plane.
Background technique
The core component of scroll compressor comprises the dynamic and static scroll of relative gear motion; Its fixed scroll of the scroll compressor of this tangerine structure is bolted on casing, drives it to rotate with respect to fixed scroll and orbiter is live axle by being provided with eccentric axial portion and main shaft part.Existing a kind of electric scroll compressor, the eccentric axial portion of the live axle of this electric scroll compressor is inserted in the center hole of orbiter by being sleeved on successively its outer joint balance piece and bearing, and the main shaft part of live axle is inserted in motor; Described eccentric axial portion is provided with the drive surface corresponding with joint balance piece, and the angle of the line at described drive surface and eccentric axial portion center and main shaft part center is 10 degree.There are the following problems in electric scroll compressor working procedure for the drive surface of the live axle of this structure: 1, starting torque is large, coefficient of refrigeration≤1.95 while stablizing 2100rpm; 2, the drive surface unbalance stress of live axle, serious wear.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of scroll compressor, and it can solve the drive surface unbalance stress of existing scroll compressor live axle, the problem that starting torque is large.
The technological scheme that technical solution problem of the present invention adopts is: this scroll compressor comprises the live axle that is provided with eccentric axial portion and main shaft part, described eccentric axial portion is set with joint balance piece, in described eccentric axial portion, be provided with the drive surface connecting with described joint balance piece endoporus, the folder degree of the face at described drive surface and described eccentric axial portion center and described main shaft part line of centres place is acute angle setting, and the angle of described angle is 15 degree~21 degree.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect having is: 1, because the folder degree of the face at drive surface and eccentric axial portion center and main shaft part line of centres place is 15 degree~21 degree, when startup, the suffered moment of torsion of live axle reduces, coefficient of refrigeration >=2.15 while stablizing 2100rpm; 2, drive surface is stressed evenly, weares and teares little.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of the live axle that joint balance piece is housed of the embodiment of the present invention.
Fig. 3 is the left view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Embodiment 1:
Scroll compressor as shown in Fig. 1 Fig. 2 and Fig. 3 comprises a kind of scroll compressor, comprise the live axle 1 that is provided with eccentric axial portion 1-2 and main shaft part 1-1, eccentric axial portion 1-2 is inserted in the center hole of orbiter 3 by being sleeved on successively its outer joint balance piece 2 and bearing, and main shaft part 1-1 is inserted in motor 4; On eccentric axial portion 1-2, have the drive surface 1-3 connecting with joint balance piece 2 endoporus, the folder degree a of the face at drive surface 1-3 and eccentric axial portion 1-2 center and main shaft part 1-1 line of centres place is acute angle setting, and the angle of angle a is 15 degree.
Embodiment 2:
The angle of angle a is 21 degree, and other features are identical with embodiment 1.
When startup, because the folder degree of the face at drive surface 1-3 and eccentric axial portion 1-2 center and main shaft part 1-1 line of centres place is 15 degree~21 degree, the suffered moment of torsion of live axle reduces, and while stablizing 2100rpm, coefficient of refrigeration is 2.19.

Claims (1)

1. a scroll compressor, comprise the live axle (1) that is provided with eccentric axial portion (1-2) and main shaft part (1-1), described eccentric axial portion (1-2) is set with joint balance piece (2), in described eccentric axial portion (1-2), be provided with the drive surface (1-3) connecting with described joint balance piece (2) endoporus, described drive surface (1-3) is acute angle setting with the folder degree (a) of the face at described eccentric axial portion (1-2) center and described main shaft part (1-1) line of centres place, it is characterized in that: the angle of described angle (a) is 15 degree~21 degree.
