Description
Technical Field
The utility model relates to a vortex formula compressor, especially vortex formula compressor's spider support technique, specifically speaking are magnetic suspension anti-rotation vortex compressor.
Background
As is known, the orbiting plates of a scroll compressor, in operation, perform mainly a translatory revolving motion. When the back of the dynamic disc is used as a supporting surface, the dynamic disc bears the axial thrust of internal working pressure during working, and the friction force of the dynamic disc causes the friction surface of the dynamic disc to be worn, consume power, generate heat and the like. At present, no good characters for solving the problem are available except for axial positioning and adoption of wear-resistant materials. Magnetic levitation can keep the friction surface at a set distance without generating distance change, and is a good friction reducing method, but according to the applicant's knowledge, no report that the magnetic levitation technology is applied to a movable scroll compressor is available at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims at having the problem that the axle rubs in the vortex compressor driving disk, designing a magnetic suspension that can eliminate frictional force and preventing rotation vortex compressor.
The technical scheme of the utility model is that:
a magnetic suspension anti-rotation scroll compressor comprises a main shaft 1, a movable disc 2 and a bearing seat 3, and is characterized in that the movable disc 2 is connected with a movable disc driving support 4, a limit ring is installed on the movable disc driving support 4, a round hole 11 for inserting a driving pin 5 is formed in the surface, opposite to the movable disc driving support 4, of the bearing seat 3, a first bearing 6 is installed between the movable disc driving support 4 and the main shaft 1, a second bearing 7 and a main shaft balancing weight 8 are installed between the bearing seat 3 and the main shaft 1, a magnetic ring coil 9 is installed between the main shaft balancing weight 8 and the movable disc driving support 4, a magnetic ring 10 is installed on the movable disc driving support 4 and the magnetic ring coil 9 in a position opposite to each other, and after the magnetic ring coil 9 is electrified, a constant gap.
The magnetic ring 10 is a permanent magnet, the magnetic ring coil 9 is an electromagnetic coil, and the polarity of the permanent magnet is the same as that of the magnetic ring coil.
The circular hole 11 is provided with a driving ring 12.
The utility model has the advantages that:
the utility model discloses from reducing coefficient of friction, systematic solution driving disk coefficient of friction problem. It makes to produce the clearance support between the friction surface through the principle that adopts the magnetic suspension, can reduce the coefficient of friction to "zero" in work, offsets gaseous axial gas power through intelligent control suspension power for driving disk during operation drive power reduces greatly, thereby reduces drive power, wearing and tearing and rub the scheduling problem that generates heat. Simultaneously, the purpose of preventing the rotation of the movable disc can be well achieved by matching with a ring pin structure, so that the efficiency of the compressor is improved by more than 30%. The structure can be used in the field of all scroll compressors, will have subversive progress on improving the efficiency of the compressor, and also makes important contribution to the new energy industry.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1.
A magnetic suspension anti-rotation scroll compressor comprises a main shaft 1, a movable disc 2 and a bearing seat 3, wherein the movable disc 2 is connected with a movable disc driving support 4, a limit ring is arranged on the movable disc driving support 4, a round hole 11 for inserting a driving pin 5 is arranged on the surface of the bearing seat 3 opposite to the movable disc driving support 4, a driving ring 12 is arranged in the round hole 11, a first bearing 6 is arranged between the movable disc driving support 4 and the main shaft 1, a second bearing 7 and a main shaft balancing weight 8 are arranged between the bearing seat 3 and the main shaft 1, a magnetic ring coil 9 is arranged between the main shaft balancing weight 8 and the movable disc driving support 4, a magnetic ring 10 is arranged on the movable disc driving support 4 and the magnetic ring coil 9 at the opposite position, the magnetic ring 10 and the magnetic ring coil 9 have the same magnetic poles after the magnetic ring coil 9 is electrified, and a constant gap is kept between the movable, thereby eliminating axial contact and providing a coefficient of friction of 0. In the embodiment, the magnetic ring 10 is an electromagnet, but preferably is a permanent magnet, and the magnetic ring coil 9 is an electromagnetic coil, and the polarity of the permanent magnet is the same as that of the magnetic ring coil, and is also an S pole or an N pole. Magnetic ring coil 9 accessible intelligent control produces the suspension and offsets gaseous axial thrust for driving force greatly reduces during the work of driving disk, thereby reduces driving force, wearing and tearing and friction and generate heat scheduling problem.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
