Anti-reversal rotary device for scroll compressor

Abstract

The invention relates to an anti-invert rotator of vortex compressor, wherein said compressor comprises: a driving motor between the main and auxiliary frames inside the frame to generate rotation function; a rotor combined on the driving motor; a driving axle supported at the main and auxiliary frames to transmit the rotation function; a rotation coil axle combined with the driving axle and meshed with the fixed coil axle to continuously move to form a couple of compress rooms; the driving axle comprises: the first axle part supported on the auxiliary frame and combined on the rotor of driving motor; and the second axle part supported at the main frame, eccentrically combined with the rotation coil axle, and rotated with the first axle part at the positive rotation, and separated with the first axle part at the reverse rotation. The invention can automatically avoid reverse rotation via driving axle, without adding additive anti-invert rotation device.

Description

Technical field [0001] The invention relates to an anti-reverse rotation device for a scroll compressor. Background technique [0002] Generally speaking, a compressor is a device that converts mechanical energy into compression energy of a compressed fluid, and can be generally divided into reciprocating type, scroll type, centrifugal type, and vane type. Among them, the scroll compressor is different from the reciprocating compressor that uses the linear motion of the cylinder, but uses a rotating body used in a centrifugal or vane compressor to suck and compress gas before discharging it. [0003] Such as figure 1 As shown, the scroll compressor in the prior art includes the following parts: a housing 1 provided with a gas suction pipe SP and a gas discharge pipe DP; each is fixed on the upper and lower sides of the inner peripheral surface of the housing 1 The main frame 2 and the sub-frame 3; the drive motor 4 installed between the main frame 2 and the sub-frame 3; the rota...

Problems solved by technology

[0008] However, in the conventional scroll compressor, under the abnormal control of the drive motor 4, when the rotor 4B reversely rotates, the drive shaft 5 also reverses in the direction of rotation of the rotor 4B. Rotate, thereby causing the above-mentioned rotating reel 6 to reversely rotate, do not perform the compression operation, or cause the gear teeth 7a of the fixed reel 7 and the gear teeth 6a of the rotating reel 6 to collide with each other and be damaged

Considering the above problems, in the prior art, an anti-reverse rotation structure (not shown) for forcibly preventing reverse rotation is installed between the main frame 2 and the drive shaft 5, but additionally installing the above structure will lead to an increase in the production cost of the compressor
