Degree is big, can satisfy demand of the compression chamber to the support strength of the larger refrigerant of pressure.And for the ease of the first support construction 5 with
Quiet part 3 is welded, and is increased link strength and air-tightness, can be set identical for the first support construction 5 and the material of quiet part 3,
Specifically, the material of the first support construction 5 in the present embodiment is identical as the material of quiet part 3, is iron and steel material quality, so that first
The intensity of support structure 5 is larger, meets the support to crankshaft 4, on the other hand by the material of the material of the first support construction 5 and quiet part 3
Matter is set as identical, convenient for being welded therebetween.As disposable embodiment, the material of the first support construction 5
It can be any other material that can satisfy intensity requirement.
The other end of crankshaft 4 in the present embodiment by the second support construction support, the periphery wall of the second support construction with
The cavity wall of accommodating cavity connects, and the Material Strength of the second support construction is bigger than the Material Strength of shell ontology 1.By by crankshaft 4
The other end is supported by the second support construction, and the both ends of crankshaft 4 can be made to have support member to be supported, so that support effect
Fruit is more preferable, and bigger than the Material Strength of shell ontology 1 by the Material Strength of the second support construction, can satisfy the need of support strength
It asks.Specifically, the material of the second support construction is steel.As disposable embodiment, the material of the first support construction 5
It any other can satisfy the material of intensity requirement.
The second support construction in the present embodiment includes support ring 7 and bearing block 8, the periphery wall and accommodating cavity of support ring 7
Cavity wall offset, bearing block 8 is installed in support ring 7.By the way that the second support construction is set as including support ring 7 and bearing block
8, so that support ring 7 and bearing block 8 cooperate common support crankshaft 4, so that the support stress of crankshaft 4 is more preferable.
The material of moving part 6 in the present embodiment is aluminium alloy.The compression process of refrigerant is realized in moving part 6 and the cooperation of quiet part 3,
But since moving part 6 is the dynamic element for compressing refrigerant, as long as the transverse tooth thickness degree of moving part 6, which is designed to work as, meets intensity requirement,
And moving part 6 is only that the pressure that the position closer from exhaust outlet is subjected to is just bigger, it is higher to be not that entire moving part 6 is born
Pressure sets aluminium alloy for the material of the moving part 6 in the present embodiment, can both expire thus in order to reduce the total weight of compressor
The demand of sufficient intensity, and aluminum alloy material is lighter, the small compressor of inertia force runs smoothly, and beneficial to vibration is reduced.
The Material Strength of end cap 2 in the present embodiment is smaller than the Material Strength of quiet part 3, and specifically, the material of end cap 2 is aluminium
Alloy, convenient for the connection of end cap 2 and shell ontology 1.
The low pressure chamber of compressor in the present embodiment further includes oil pump 9, for being compressor oil-supplying.Since it is only to compress
Machine provides oil, and is set to the low pressure chamber of compressor, and the pressure of receiving is smaller, can be by oil pump 9 in order to reduce the total weight of compressor
Material be set as aluminium alloy.
The low pressure chamber of compressor in the present embodiment further includes motor 10.By the low pressure that motor 10 is arranged in compressor
Chamber can cool down motor 10 by the lower refrigerant of suction temperature, prevent 10 temperature of motor excessively high in the process of running,
Influence the operational reliability of compressor.
Compressor in the present embodiment is vehicle-mounted compressor, can satisfy the light-weighted requirement of vehicle-mounted compressor, and can be with
Realize biggish refrigerated medium heat.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
