Description
Technical field
The present invention relates to a kind of branch support technologies of whirlpool trip formula compressor, especially scroll compressor, specifically
It is a kind of anti-rotation screw compressor of magnetic suspension.
Background technique
It is well known that the Moving plate of scroll compressor is at work, it is substantially carried out the rotary motion of translation.Its back side conduct
Supporting surface at work, carries the axial thrust of internal process pressure, and frictional force size leads to Moving plate friction surface wear, function
Consumption and fever etc..To this at present in addition to carrying out axially position and using the solution text that other than wear-resistant material, there is no.And magnetic suspension
The distance that rubbing surface can be made to be maintained at setting will not generate the variation of distance again, be a kind of good antifriction method, but according to application
Known to people, magnetic levitation technology there is no to apply the report in scroll compressor moving plate at present.
Summary of the invention
The purpose of the present invention is there are problems that axis bribes friction scroll compressor moving plate, designing a kind of can eliminate and rubbing
Wipe the anti-rotation screw compressor of magnetic suspension of power.
The technical scheme is that
A kind of anti-rotation screw compressor of magnetic suspension, it includes main shaft 1, Moving plate 2 and bearing block 3, it is characterized in that the Moving plate 2
It is connected with Moving plate driving support 4, spacing collar is installed on Moving plate driving support 4, drives 4 phase of support in bearing block 3 and Moving plate
Pair face be equipped with inserting drive pin 5 circular hole 11, Moving plate driving support 4 and main shaft 1 between first bearing 6 is installed, in axis
It holds and second bearing 7 and main shaft clump weight 8 is installed between seat 3 and main shaft 1, between main shaft clump weight 8 and Moving plate driving support 4
Magnetic ring coil 9 is installed, with the magnetic ring coil 9 on Moving plate driving support 4, magnet ring 10, magnet ring are installed at relative position
After coil 9 is powered, the gap that is kept constant between magnet ring 10 and magnetic ring coil 9.
The magnet ring 10 is permanent magnet, and the magnetic ring coil 9 is electromagnetic coil, the polarity and magnet ring of permanent magnet
The magnetism of coil is identical.
Drive ring 12 is installed in the circular hole 11.
Beneficial effects of the present invention:
The present invention solves the problems, such as Moving plate coefficient of friction from coefficient of friction, system is reduced.It is by using maglev
Principle makes to generate gap support between rubbing surface, can be reduced to coefficient of friction " zero ", be suspended at work by intelligent control
Power offsets the axial gas power of gas, so that driving force greatly reduces when Moving plate works, to reduce driving force, wear and rub
The problems such as wiping fever.Ring pin structure is cooperated to can solve the anti-rotation purpose of Moving plate simultaneously, so that compression functional efficiency improves
30% or more.This structure can be used for all scroll compressor fields, will have subversive progress to improving on compressor efficiency,
Also important contribution is made for New Energy Industry.
Detailed description of the invention
Fig. 1 is the principle of the present invention structural schematic diagram.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of anti-rotation screw compressor of magnetic suspension, it includes main shaft 1, Moving plate 2 and bearing block 3, and the Moving plate 2 connects
There is Moving plate to drive support 4, spacing collar is installed on Moving plate driving support 4, it is opposite with Moving plate driving support 4 in bearing block 3
Face is equipped with the circular hole 11 of inserting drive pin 5, and drive ring 12 is equipped in circular hole 11, is pacified between Moving plate driving support 4 and main shaft 1
Equipped with first bearing 6, second bearing 7 and main shaft clump weight 8 are installed between bearing block 3 and main shaft 1, in main shaft clump weight 8
Moving plate driving support 4 between magnetic ring coil 9 is installed, Moving plate driving support 4 on the magnetic ring coil 9, relative position
Place is equipped with magnet ring 10, and after magnetic ring coil 9 is powered, magnet ring 10 is identical with 9 magnetic pole of magnetic ring coil, the principle mutually torn open according to the same sex,
Make the gap kept constant between 3 end face of Moving plate 2 and bearing block, to eliminate axially contact, makes coefficient of friction 0.Specifically
Magnet ring 10 described in when implementation is electricity to magnet, can also be permanent magnet, it is preferred that permanent magnet, and magnetic ring coil 9 is electricity
Magnetic coil is caused, the polarity of permanent magnet and the magnetism of magnetic ring coil are identical, are all the pole S or are all the pole N.Magnetic ring coil 9 can pass through
Intelligent control generates suspending power to offset the axial thrust of gas, so that driving force greatly reduces when Moving plate works, to reduce
The problems such as driving force, abrasion and frictional heating.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
