Description
Technical field
The utility model belongs to the air conditioner refrigerating field, especially relevant for a kind of air condition compressor that can increase the join strength of compressor pump and housing, the vibration that reduces compressor and noise and reduce the amount of deflection of bent axle.
Background technique
Have only bent axle and rotor to rotate in the working procedure of air condition compressor, the remaining part of compressor pump need be welded on the housing.The solder joint of the housing and the pump housing not only is subjected to the effect of static load in compression process, more be subjected to the effect of dynamic load, and dynamic load is principal element, and under the effect of dynamic load, the solder joint position is easy to take place fatigue fracture, compressor failure.
The noise of compressor roughly is divided into three kinds: first kind of solid propagation sound that the vibrating source that is pump housing part and motor section are graded causes, second kind be refrigerant gas in the space resonance noise that enclosure interior inspires, the rigid body chatter of the third low frequency range that to be compressor produce by vibration as rigid body.The variation of bond pad locations can change the stressed of housing and distortion, and the vibration and the noise of compressor exerted an influence.
The another one effect of six spot welding (or three spot welding) is the amount of deflection of restriction bent axle, bent axle occurs bending and deformation under the effect of axial force, wearing and tearing aggravation between excessive then bearing of bent axle amount of deflection and the bent axle, and increase the ricing in electric machine rotor gap, increase electromagnetic noise, reduced motor properties.
The big discharge capacity rotor compressor of technology is identical with existing rotor common compressor welding manner now, all adopts six spot welding, and their connection power should be identical.But the pump housing of big capacity compressors and the static load of housing and dynamic load be big than existing machine all, if the compressor long-time running, big discharge capacity adopts common six spot welding may be because of insufficient strength generation fatigue fracture.
The shell of rotor compressor directly becomes greatly, and large shell caliber compressor housing rigidity reduces, and hull vibration is strengthened, and noise is higher, and the noise that test records existing rotor compressor is bigger.Big capacity compressors unbalance moment strengthens, and will produce bigger noise.
The big stressed deterioration of capacity compressors bent axle, and the length of bent axle lengthening, these factors all cause the bent axle amount of deflection to become big, increase the contact pressure between bent axle and the bearing, aggravated the abrasion of bent axle, the ricing in rotor gap increases, cause electromagnetic noise to increase, electric efficiency reduces.
For general rotor compressor, adopt common three spot welding and six spot welding can satisfy requirement of strength, but, adopt the join strength between the possible housing of existing six spot welding and the pump housing not enough big capacity compressors; And the compressor of big discharge capacity faces severe noise challenge.For join strength, reduction vibration of compressor and the noise, the minimizing bent axle amount of deflection that guarantee the pump housing and housing, this patent proposes novel welding manner and supports the pump housing.
