Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of bent axle, especially a kind of dual-gripper compressor crank shaft.
Background technology
Based on efficient purpose, the motor height of rotary compressor gradually increases, and the diameter of axle of bent axle gradually reduces, such as
This, then in the running, the amplitude that bent axle and rotor are swung together is larger, so as to cause wiping is generated between stator and rotor
It touches；In addition, due to the swing of bent axle, causes the abrasion between bent axle and compression assembly to increase, eventually lead to rotary compressor
Less reliable.
To improve this situation, there are the patent of related dual-gripper assembling scheme and document to occur successively both at home and abroad, that is, removes in place
Outer in one support of setting on the compression assembly of the lower end of motor, also in shell upper end, i.e. another support is arranged in the upper end of motor；So
And unfortunately in these dual-gripper assembling schemes, the bearing in another support all only simply limits bent axle, axis
It holds and is not carried out between bent axle to core clearance fit, inevitably there is initial assembly force between bearing and bent axle, it is this
Assembling scheme can no doubt realize limit of the bearing to bent axle, but since the presence of initial assembly force causes the abrasion of bent axle to increase,
Along in another support bearing fuel feeding itself not enough, poor lubrication, finally so that reliability deteriorate, while bring efficiency it is low and
The big counter productive of noise.
