Abstract

The invention relates to a double-ended scroll compressor. A pair of scroll compressors with equal size and in opposite directions is respectively arranged at both ends of a driving mechanism. The pair of scroll compressors has equal size and mass, and is only in opposite directions of shapes and scroll lines; when two moving scrolls circumferentially swing around a main shaft, the generated rotary inertia force counteracts the rotary inertia moment generated to a main bearing, thus omitting a complicated differential balance mechanism, so that the scroll compressor has more compact mechanism, simpler structure, improved efficiency and reduced vibration and noise.

Description

Double-head scroll compressor

Technical field

The present invention relates to scroll compressor, particularly a kind of low cost, high performance double-head scroll compressor.

Background technique

No matter conventional scroll compressor is vertical or horizontal, all is single head, and just at live axle drives a compressor, and its shortcoming is to need complicated dynamic balancing, causes complex structure, volume is big, efficient is low.

The purpose of invention

The purpose of this invention is to provide a kind of double-head scroll compressor, it not only compact structure, simple structure, owing to removed complicated moving flat permanent mechanism efficient is improved.

Technological scheme

The object of the present invention is achieved like this: make big or small identical respectively at two of driving mechanism, direction pair of opposite scroll compressor, place the two ends of driving mechanism respectively, because the moving scroll of this a pair of compressor is big or small identical, quality equates, just the direction of shape and spiral type line is opposite, this two moving scroll is cancelled each other at the rotating inertia force that produces when the alignment of shafts is made circle swing and to the rotatory inertia moment that main shaft bearing produces, do not need to add again the dynamic balancing that equilibrium block can be realized the machine movement system, also just saved complicated dynamic balancer, double end is horizontal to be pressed in the lubricating cup of support by transport pipe with lubricant oil vertical compressor, enters main shaft bearing lubricating bearings or axle sleeve.

Beneficial effect

Owing to adopt such scheme, make the structure of scroll compressor compact more, construct simplyr, saved power, improved efficient, reduced vibration and noise.

The drawing explanation

The present invention is further described below in conjunction with drawings and Examples:

Fig. 1 is the horizontal machine of the double end of belt pulley of the present invention or gear drive.

Fig. 2 is the horizontal machine of the motor-driven double end of the present invention.

Fig. 3 is the motor-driven double-head vertical machine of the present invention.

Fig. 4 is horizontal main bearing lubrication chart

Fig. 5 is vertical main bearing lubrication chart

Among the figure: the 1st, quiet whirlpool dish 2 is that movable orbiting scroll 3 is that casing 4 is that main shaft 5 is that axle sleeve 6 is that frame 7 is that lubricating cup 8 is that transport pipe fixed scroll 1 in the example of Fig. 1, Fig. 2 and Fig. 3 is made big or small identical with moving scroll 2, oppositely opposite, crux be that the quality of two moving scroll 2 will equate, just shape and spiral type line want opposite mutually, two moving scroll 2 are cancelled each other at the rotating inertia force that produces when circle swing is made at main shaft 4 centers and to the rotatory inertia moment that main bearing 5 produces in the running, do not need to add the dynamic balancing that equilibrium block can be realized the machine movement system.

Fig. 4 and Fig. 5 utilize pressure reduction lubricated to main bearing 5, and high pressure oil enters in the lubricating cup 7 of frame 6 through transport pipe 8, thereby main bearing 5 and main shaft 4 are lubricated.

Claims

1, a kind of double-head scroll compressor comprises by a pair of equal and opposite in direction, two scroll compressors that direction is opposite, be worth two ends respectively in driving mechanism, it is characterized in that: the Moving plate equal and opposite in direction of two compressors, quality equate, the direction of spiral type line is opposite, the rotating inertia force that causes two moving scroll to produce when the alignment of shafts is swung reaches the rotatory inertia moment that main bearing is produced and cancels out each other, and does not need to add the dynamic balancing that equilibrium block can be realized the machine movement system again.Can be lubricated to the lubricated of main shaft bearing with pressure reduction.

2, double-head scroll compressor according to claim 1 is characterized in that: driving mechanism can be a motor.

3, double-head scroll compressor according to claim 1 is characterized in that: driving mechanism can be a belt pulley.
