Abstract
The utility model discloses a compressor with non-magnetic high-manganese steel balance weights, belonging to the technical field of compressors. The compressor comprises a shell, wherein a motor stator is fixedly arranged in the shell; a motor rotor is matched in the motor stator; an eccentric crankshaft is fixedly arranged in the motor rotor; a movable piston is fixedly arranged at the lower end of the eccentric crankshaft; the movable piston is located in a cavity formed by an upper flange, a lower flange and a cylinder; and the compressor is characterized in that balance weights composed of non-magnetic high-manganese steel containing iron, manganese, chromium and carbon are fixedly arranged on the motor rotor. The compressor with non-magnetic high-manganese steel balance weights, disclosed by the utility model, has simple structure and reasonable design; a main balance weight and an auxiliary balance weight which are composed of non-magnetic high-manganese steel consisting of the raw materials such as iron, manganese, chromium, carbon and the like are arranged on the upper and lower end surfaces of the motor rotor; and the magnetic permeability, vibration, noise and balance completely meet the usability of the compressor, and the production cost of the compressor is greatly reduced.
Description
Technical field
The utility model belongs to the Compressor Technology field, is specifically related to a kind of compressor that is provided with without magnetic high manganese steel equilibrium block.
Background technique
Compressor is in when normal operation, its inner rotor rotating speed can access 800 turn～8000 rev/mins because its live axle is eccentric crankshaft, can produce eccentric force during the eccentric crankshaft rotation, if do not carry out balance, then vibration of compressor can be very large, even can't work.And in the prior art because the restriction of equalizing feature aspect material, structure, assembly space and set-up mode, thereby affect compressor design and cost.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to design a kind of technological scheme that is provided with without the compressor of magnetic high manganese steel equilibrium block is provided.
Described a kind of compressor that is provided with without magnetic high manganese steel equilibrium block, comprise housing, be fixedly installed motor stator in the housing, be equipped with rotor in the motor stator, be fixedly installed eccentric crankshaft in the rotor, the eccentric crankshaft lower end is fixedly installed movable piston, and movable piston is arranged in the cavity that upper flange, lower flange and cylinder consist of, and it is characterized in that being fixedly installed on the described rotor by the equilibrium block that consists of without magnetic high manganese steel that contains iron, manganese, chromium and carbon.
Described a kind of compressor that is provided with without magnetic high manganese steel equilibrium block is characterized in that described equilibrium block comprises secondary equilibrium block and the main equilibrium block that is symmetricly set on the rotor upper and lower end face.
Above-mentioned a kind of compressor that is provided with without magnetic high manganese steel equilibrium block, simple in structure, reasonable in design, the main equilibrium block and the secondary equilibrium block that consist of without magnetic high manganese steel that are comprised of raw materials such as iron, manganese, chromium and carbon are set in the rotor upper and lower end face, its permeability, vibrations, noise and balance satisfy the usability of compressor fully, and have reduced the cost of production of compressor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the secondary equilibrium block of 1-; The 2-rotor; The 3-motor stator; The 4-eccentric crankshaft; 5-master's equilibrium block; The 6-upper flange; The 7-movable piston; The 8-cylinder; The 9-lower flange; The 10-housing.
Embodiment
Further specify the utility model below in conjunction with embodiment.
As shown in the figure, a kind of compressor that is provided with without magnetic high manganese steel equilibrium block comprises housing 10, is provided with rotor 2, motor stator 3, eccentric crankshaft 4, upper flange 6, movable piston 7, cylinder 8 and lower flange 9 in the housing 10.Rotor 2 is equipped with in motor stator 3, and is fixedly installed eccentric crankshaft 4 in the rotor 2, and eccentric crankshaft 4 lower ends are fixedly installed movable piston 7, and movable piston 7 is arranged in the cavity that upper flange 6, lower flange 9 and cylinder 8 consist of.Because eccentric crankshaft 4 adopts the eccentric structure design, eccentric crankshaft 4 can produce eccentric force in rotary course, can produce vibration, need balance so that minimum vibration, therefore in the upper and lower end face of rotor 2 secondary equilibrium block 1 is set and main equilibrium block 5 carries out equilibrium of forces and equalising torque.
Wherein main equilibrium block 5 is by making without magnetic high manganese steel, without containing Mn 10-19% in the magnetic high manganese steel, and Cr 5-12%, C≤0.8%, Cu≤1.5%, S≤0.3%, Si≤1.0%, all the other are Fe and inevitably microimpurity and element.Secondary equilibrium block 1 also can be selected to make without magnetic high manganese steel according to compressor design needs and cost control.
Shown in the above and the figure only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
