Description

Device for reducing noise of electric scroll compressor

Technical Field

The utility model relates to a reduce device of electronic scroll compressor noise.

Background

With the increasing popularization of electric automobiles, people have higher and higher requirements on the electric automobiles, and especially have high requirements on the comfort of the electric automobiles, wherein noise is an important problem to be solved.

Compared with the traditional compressor for the automobile air conditioner, the electric scroll compressor adopts an independent power device and a special mechanical structure, the rotating speed of the electric scroll compressor reaches more than 6000 rpm, and certain noise can be generated inevitably. The purpose of the air conditioner of the automobile is to bring a comfortable environment to passengers, so that the problem of noise solving is urgent for various manufacturers. The main part of the noise generation is in the portion between the compressor crankshaft and the scroll, and therefore, structural improvement is required for noise reduction.

Disclosure of Invention

For overcoming the deficiencies of the prior art, the utility model aims at providing a device for reducing the noise of an electric scroll compressor, which adopts a flexible connection between a balance block and a scroll plate, and realizes the effective reduction of the noise generated when the compressor operates.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

the utility model provides a reduce device of electronic scroll compressor noise, includes the vortex dish, the balancing piece, the supporting disk, the vortex dish is connected with the supporting disk, the balancing piece sets up in the supporting disk, and is connected with the bent axle tip, be connected with the bearing between vortex dish and the balancing piece, still include adjusting shim, O type rubber circle, the balancing piece is outer to be formed the abduction end along the tip abduction, form the recess between abduction end and the bearing, be provided with O type rubber circle in the recess, adjusting shim sets up between vortex dish and supporting disk.

The vortex disc consists of a movable vortex disc and a fixed vortex disc which do relative motion, the movable vortex disc is arranged in the fixed vortex disc, the outer diameter of a balance block is in clearance fit with the inner wall of a bearing, and the outer wall of the bearing is connected with the movable vortex disc.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure is reliable, has played the effect of making an uproar of falling. Adopt O type rubber circle flexonics balancing piece and bearing, make to be the flexible coupling between balancing piece and the bearing, avoided the hard joint, noise that can effectual reduction compressor production when operation. The balance block adopts an outward expansion structure, so that the O-shaped rubber ring can be fixed between the balance block and the bearing, and the maintenance frequency is reduced. Set up adjusting shim between vortex dish and supporting disk, not only satisfy the flexible cooperation of electronic scroll compressor power, quiet vortex dish, but also make the noise reduction of compressor, reduce noise pollution.

Fig. 2 is a schematic connection diagram of an O-ring.

In the figure: 1-static vortex plate 2-dynamic vortex plate 3-adjusting shim 4-bearing 5-O type rubber ring 6-balance block 7-crankshaft 8-supporting disk.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

See fig. 1, fig. 2, a reduce device of electronic scroll compressor noise, including the vortex dish, the balancing piece 6, supporting disk 8, the vortex dish is connected with supporting disk 8, balancing piece 6 sets up in supporting disk 8, and with 7 end connection of bent axle, be connected with bearing 4 between vortex dish and the balancing piece 6, still include adjusting shim 3, O type rubber circle 5, balancing piece 6 is outer to be formed the abduction end along the tip abduction, form the recess between abduction end and the bearing 4, be provided with O type rubber circle 5 in the recess, adjusting shim 3 sets up between vortex dish and supporting disk.

The scroll comprises a movable scroll 2 and a fixed scroll 1 which move relatively, the movable scroll 2 is arranged in the fixed scroll 1, the inner diameter of a balance block 6 is matched with the end part of a crankshaft 7 (in clearance fit), the outer diameter of the balance block 6 is in clearance fit with the inner wall of a bearing 4, and the outer wall of the bearing 4 is connected with the movable scroll 2.

In the operation process, when the pressure of compressed gas is too large or the sizes of the movable vortex disc 2 and the fixed vortex disc 1 are deviated, the movable vortex disc 2 can be always propped against by the adjusting gasket 3, the axial position of the movable vortex disc 2 can be adjusted at any time, the movable vortex disc 2 and the fixed vortex disc 1 are always in a sealing fit state, and meanwhile, the noise of axial relative motion is reduced. Can collide with balancing piece 6 when moving 2 axial adjustment positions of vortex dish, produce the noise, utilize O type rubber circle 5 to let and move 2 axial adjustment of vortex dish, can avoid two parts to produce the noise again, avoided hard contact to satisfy the flexible cooperation of spare part.

The utility model discloses a purpose of noise reduction (5-10dB) by a wide margin has been realized to passenger's comfort level has been improved.
