Description
Technical field
The utility model relates to arrive refrigeration compressor art, specifically a kind of refrigeration compressor rubber pad.
Background technique
Currently, positive displacement compressor is very widely used in refrigeration compressor, it is driven by piston crank link mechanism and is lived
Plug, moves back and forth in cylinder, realizes the refrigeration cycle of compression, condensation, expansion, evaporation.In the course of work, movement knot is acted on
Power on structure has inertia force, gas force and the frictional force relative to moving surface.Wherein, inertia force and gas force are to cause to compress
The main reason for machine vibration.
The shock mitigation system of compressor includes internal, external two parts.Inside includes ontology, spring and under-chassis, and outside includes
Cabinet bottom steel plate of rubber pad, refrigerator or refrigerator etc., collectively constitutes shock mitigation system.Wherein, the structure of ontology is more complex, spring
Need to take into account vibration and anticollision, under-chassis material is metal, and cabinet bottom steel plate once designs completion, general little change.And rubber
Rubber mat can provide important buffer function between compressor and cabinet, and structure and material can be adjusted according to client
Whole, relatively other several type components have stronger flexibility.Two kinds of Fig. 1 and as existing common rubber pad shown in Fig. 2
Structural schematic diagram, rubber pad include the portion that is coupled 1 and carrying 11 two parts of work department, and being coupled portion 1 includes upper and lower two
Section cylindrical structure, the effect of two sections of cylindrical structures are limitation and cooperation respectively.Most the preceding paragraph cylindrical structure 12(is contained into chamfering,
Claim securement head) it is packed into the mounting hole of compressor sole, it is then attached to lower section cylindrical structure 13(embedded division) on.Carrying installation
