Description
Technical Field
The utility model relates to a scroll compressor, in particular to eccentric balance sleeve of scroll compressor and compressor of making an uproar falls.
Background
The scroll compressor is mainly applied to the field of new energy automobile air conditioners and provides a comfortable environment for drivers, but the new energy automobile has higher requirements on driving feeling and comfort, and compared with a traditional fuel oil automobile, the driving power of an electric automobile is changed into electromagnetism and a motor from an engine. The vibration and noise of the compressor are mainly caused by electromagnetic noise of a motor and a controller, friction noise of a rotating mechanism, collision noise of a movable disc and a static disc, collision noise of an eccentric balance block and a crankshaft, gas pulsation noise and the like.
The compressor controls the permanent magnet synchronous motor to operate at a high speed through the controller, the rotor and the crankshaft do circular motion, and the movable scroll is driven to revolve and translate around the fixed scroll through the action of the balance block and the crank pin, the eccentric balance block plays a role in limiting and providing radial flexible compensation quantity in the structure, the eccentric balance block restricts the flexible compensation quantity through the contact with the crankshaft, accumulated tolerance is generated in the processing and assembling process of the compressor, in the high-speed operation of the compressor, the eccentric balance block needs to be continuously subjected to flexible compensation in order to ensure that the movable scroll and the fixed scroll are perfectly meshed, the balance block and the crankshaft are subjected to limiting collision, and unnecessary noise and vibration are generated.
Disclosure of Invention
The utility model aims to solve the technical problem that a eccentric balance cover of scroll compressor of making an uproar falls is provided, and eccentric balance cover and bent axle collision are soft contact, reduce noise and vibration that the collision produced.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides an eccentric balanced cover of scroll compressor of making an uproar falls, including balanced cover body, the plastic pad, balanced cover body includes the cylinder sleeve body, the fan-shaped cover body, the cylinder sleeve body and the fan-shaped cover body are endocentric integrated into one piece structure, the internal eccentric pinhole that is equipped with of cylinder sleeve, pinhole one end is equipped with the counter bore, be equipped with on the fan-shaped cover body of counter bore one side with the first arc recess of fan-shaped cover body concentricity, be equipped with second arc recess on the fan-shaped cover body of the offside of first arc recess, be equipped with confined groove ring on first arc recess internal surface and fan-shaped cover external surface, the inslot is moulded plastics and.
The plastic pad is 0.6-1mm higher than the outer surface of the balance sleeve body.
The distance between the bottom surface of the arc-shaped groove and the bottom surface of the counter bore is 1.5-2 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses reduce the area of the collision contact of eccentric balance cover and bent axle, reduce noise and the vibration that the collision produced, through optimizing the structure of eccentric balance cover in addition, change the material of collision contact, change the collision of plastics and steel into by the collision of original steel and steel, reduce the collision noise.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a plan view of the present invention.
Fig. 3 is an assembly view of the eccentric balance sleeve.
In the figure: balance sleeve body 1, plastic pad 2, cylinder cover body 3, fan-shaped cover body 4, pinhole 5, counter bore 6, first arc recess 7, second arc recess 8, groove ring 9, bent axle 10.
Detailed Description
The following further describes the embodiments of the present invention with reference to the attached drawings:
as shown in fig. 1-3, an eccentric balance sleeve of a noise reduction scroll compressor comprises a balance sleeve body 1 and a plastic pad 2, wherein the balance sleeve body comprises a cylindrical sleeve body 3 and a fan-shaped sleeve body 4, the cylindrical sleeve body 3 and the fan-shaped sleeve body 4 are of a concentric integrated structure, an eccentric pin hole 5 is arranged in the cylindrical sleeve body 3, a counter bore 6 is arranged at one end of the pin hole 5, a first arc-shaped groove 7 concentric with the fan-shaped sleeve body 4 is arranged on the fan-shaped sleeve body 4 on one side of the counter bore 6, a second arc-shaped groove 8 is arranged on the fan-shaped sleeve body 4 on the opposite side of the first arc-shaped groove 7, a closed groove ring 9 is arranged on the inner surface of the first arc-shaped groove 7 and the outer surface of the fan-shaped sleeve body. The plastic pad 2 is 0.6-1mm higher than the outer surface of the balance sleeve body 1. The distance between the bottom surface of the first arc-shaped groove 7 and the bottom surface of the counter bore 6 is 1.5-2 mm.
The plastic pad reduces the area of the collision contact of eccentric balance cover and bent axle, reduces noise and vibration that the collision produced, and through the structure of optimizing eccentric balance cover, the material of change collision contact changes the collision of plastics and steel into by the collision of original steel and steel in addition, reduces the collision noise.
The above is only the basic principle of the present invention, not to the present invention makes any limitation, all the bases of the present invention are the same changes and modifications to the above, all within the scope of the protection scheme of the present patent technology.
