Abstract

A rolling rotary car air-conditioning compressor belongs to the car air-conditioning compressor field. To solve the shortcomings of the existing air-conditioning machinery, the utility model aims to apply to the rolling rotary car air-conditioning compressor for small cars through the increase to two cylinder bodies. The utility model consists of a shell, a front end cover and an axis. The two cylinder bodies are positioned between the front end cover and a capping on the axis of the shell. Inside the cylinder body is arranged an eccentric ring, the outside of which is provided with a bearing pressure ring. A self-adjustment locking device consisting of a finger and a pressure spring is positioned in the eccentric ring and the axis. On the cylinder body is positioned a sliding block, on which a lever spring and a holding device consisting of a floating bracket positioned on a partition board. The utility model improves on the basis of the previous design of single-cylinder compressor and still preserves the previous operation principle and property and the compact structure. The size of the contour equals or is smaller than the previous single-cylinder compressor.

Description

Rolling revolving formula automobile air conditioner compressor

Technical field:

The utility model belongs to the automobile air conditioner compressor field.

Background technique:

Existing automobile air conditioner compressor major part is eddy type, inclined disc type structure, and power all between three kilowatts to seven kilowatts, can't be used for vehicle, the agricultural vehicle of little discharge capacity, and noise is big, the cost height.

The patent No. is that the rolling revolving formula automobile air conditioner compressor of ZL95235477.2 is a kind of single cylinder rolling revolving formula automobile air conditioner compressor, and its shortcoming is a unstable working condition, and centrifugal force is bigger, and pressure ring and inboard wall of cylinder block wearing and tearing are bigger.

Technology contents:

In order to solve above-mentioned shortcoming, the purpose of this utility model is by being increased to the rolling revolving formula automobile air conditioner compressor that two cylinder bodies go for dilly.

The utility model is made up of housing, front cover, axle, between front cover and the gland two cylinder bodies are installed on the axle in housing, eccentric hoop is installed in cylinder body, the eccentric hoop outside is equipped with the bearing type pressure ring, in eccentric hoop and axle, be provided with the locking device of mediation certainly that finger and stage clip are formed, cylinder body and on slide block is installed, the hold down gag that lever spring and floating bracket are formed is installed on slide block, floating bracket is installed on the dividing plate.

The utility model is improved on the single cylinder compressor basis of former invention, and it still keeps original working principle and characteristic, and the compact structure external dimension are equal to or less than former single cylinder compressor.

The utlity model has following advantage:

1, is owing to be provided with the self-regulated inter space device, can adjusts the movement clearance between needle bearing formula pressure ring and cylinder body automatically;

2, two eccentric hoops that are mounted on the axle are 180 degree, and its centrifugal force when motion is reduced, and guarantee running balance, the working stability of axle, and working efficiency improves 20% on former basis;

3, be to use Lever type stage clip and unsteady supporting frame, eradicated the damage that elasticity resonance causes under the state that runs up and guaranteed the slide block working stability;

4, be to improve back compact structure, simple, processing cost is low, and is easy to manufacture, and using scope enlarges, and can be used as the air condition compressor of all kinds of automobiles, particularly automobile with small output volumn, agricultural vehicle.

Fig. 2 is the schematic representation after the utility model twin-tub and axle are installed with eccentric hoop;

Fig. 3 is the local enlarged diagram of the utility model Fig. 1 C portion;

The schematic representation of working between Fig. 4 the utility model lever spring and support and two slide blocks.

Embodiment:

The utility model is made up of housing 1, front cover 3, axle 2, it is characterized in that: between front cover 3 and the gland 6 two

cylinder bodies

4 and 5 are installed on the axle 2 in housing 1, eccentric hoop 11 is installed in

cylinder body

4 and 5, eccentric hoop 11 outsides are equipped with bearing type pressure ring 10, in eccentric hoop 11 and axle 2, be provided with the locking device of mediation certainly that finger 12 and stage clip 13 are formed, slide block 9 is installed on

cylinder body

4 and 5, the hold down gag that lever spring 8 and floating bracket 7 are formed is installed on slide block 9, and floating bracket 7 is installed on the dividing plate 14.

In rolling revolving formula twin-tub, the above automobile air conditioner compressor of twin-tub, the structure of split assembling axle, two eccentric hoops that are installed on the axle are 180 degree, in axle and in the hole on the eccentric hoop self-reacting device are housed, and its self-reacting device is made of finger and the stage clip in the hole that is contained on axle and the eccentric hoop.

The pressure ring that is installed on the eccentric hoop is a needle bearing formula pressure ring, and eccentric hoop and the mutual friction of bearing type pressure ring are improved to rolling friction by sliding friction when work, and the friction between needle bearing formula pressure ring and end cap and dividing plate is the sliding friction of oil clearance.

Resetting and the close bonding structure of assurance and needle bearing formula pressure ring of slide block, the Lever type stage clip is installed in floating bracket on the dividing plate by two ends, it keeps Lever type stage clip can guarantee that the bus and the needle bearing formula pressure ring cylindrical bus of the R2.5 arc surface of two slide blocks fit closely, makes the high low pressure chamber be in good working order.
