Description
Technical field
The utility model relates to the refrigeration compressor field, relates in particular to a kind of supporting construction of refrigeration compressor motor internal.
Background technology
General refrigeration compressor mainly is made up of motor, cylinder block and shell body three parts, and wherein motor is made of stator core, stator winding and rotor; The built-in piston of cylinder block is fixedlyed connected with motor stator core with piston rod and by cylinder block; One bearing is located at the cylinder block middle part, and a bent axle passes bearing rotor is connected with piston rod, and stator core then is fixed in the shell body of compressor.
Because when the motor of refrigeration compressor the inside rotates, bring by a relatively large margin vibration can for compressor integral body, cause very big operating noise, therefore for compressor is reduced to minimum to the influence of environment, improve the anti-seismic performance of compressor, the motor stator of the compressor the inside of refrigerator/idle call is not the lower house that is directly fixed on compressor generally, but relies on several support springs that motor suspension is got up.For motor stator and support spring is better fixing, way commonly used at present is, a stator support plate that has a plurality of projections is installed at motor stator bottom margin place, and the projection of stator support plate is inserted support spring inside, be connected with lower house by support spring then.The weak point of this method is: 1. support spring is easy to break away from the projection of stator support plate, makes the compressor motor internal unbalance; 2. when bigger transverse deformation takes place support spring, be easy to expose iron core coil partly and contact, cause the internal short-circuit accident of compressor with the stator lower end; The production cost height, install inconvenient.
The utility model content
The supporting construction that motor in a kind of refrigeration compressor is provided of the present utility model is installed to lower house by this supporting construction with the motor of compressor, has effectively to prevent characteristics such as stator coil and support spring contact wear, production cost are low, easy for installation.
The utility model adopts following technical scheme:
The supporting construction of motor in a kind of refrigeration compressor, described refrigeration compressor include housing and place housing interior motor and cylinder block, built-in piston of cylinder block and piston rod; Motor is made of stator core, stator winding and rotor; Cylinder block is fixedlyed connected with stator core by cylinder block, and a bearing is located at the cylinder block middle part, and a bent axle passes bearing rotor is connected with piston rod; Stator core is connected with housing by supporting construction, supporting construction comprises support spring and support unit, support unit is installed on stator core bottom margin place, support spring is between support unit and housing, cylinder block is fixedlyed connected with stator core and make the bolt head of bolt be positioned at the lower end of stator core with bolt, it is characterized in that: described support unit comprises protruding cap portion, support, joint pin and skirt section, protruding cap portion is positioned at the support top, joint pin is positioned at the support below, the skirt section is positioned at joint pin and is connected in support edge outward, a recess is established at the middle part of joint pin and support, and support unit is installed to stator core bottom margin place by the bolt head that recess is nested into bolt.
For improving insulating properties, support unit is made of insulating materials.
The effect with the support unit location is played by protruding cap portion, and protruding cap portion leans on the bottom outer rim to match with stator core.
Be provided with the bolt head interference fit of recess and bolt in the support unit.
The skirt section of support unit is played support spring and is exposed the effect that the iron core coil sections is isolated, and it highly is slightly larger than the height that the iron core coil sections is exposed in the stator lower end.
As optimization, the skirt section of support unit is an arc-shaped concave, and the inside radius of arc-shaped concave is slightly larger than the external diameter of support spring;
In sum, the utlity model has following characteristics:
1. can effectively avoid contacting of stator coil and support spring, guarantee that stator coil is not frayed, safety durable and simple in structure, easy for installation;
2. the skirt section of support unit can effectively suppress the transverse deformation of support spring, has reduced the probability that spring removal and stator break away from.
