Abstract
The utility model relates to a compressor connecting rod for reciprocating type refrigeration equipment. The connecting rod is characterized in that the connecting rod consists of a connector of a big head and a connector of a small head, the connector of a small head can be connected with the connector of a big head, a snap spring groove is arranged at the fitting part of the two sections of connectors, and the two sections of connectors are fixed by a snap spring during the assembly. The utility model reduces connecting rod assembly difficulty, and the processing accuracy is easily ensured.
Description
Technical field
The utility model relates to the connecting rod of the compressor that is used for reciprocatable refrigerating equipment.
Background technique
Tradition is used for reciprocatable refrigerating equipment compressor connecting bar and mainly is divided into two kinds of integrated type and split types.
Use the integrated type connecting rod, needs be opened mount inlet in advance and cause the sealing area of cylinder body and piston to reduce on cylinder block when connecting piston and connecting rod with pin, have reduced the working efficiency of compressor.
The split type connecting rod of known type is two-part with the connnecting rod big end subdivision mainly, and connects with bolt or other fixing devices.Because the requirement on machining accuracy of connecting rod is higher, even slight departing from takes place the parallelism between the connecting rod CONCENTRIC REDUCER, also will influence the running of reciprocating machine.And the partition patterns that adopts known type is carried out the bar linkage structure of subdivision, machining accuracy be cannot say for sure to demonstrate,prove, the surface of contact of connnecting rod big end and big skull easily deforms simultaneously, the full circle degree of connecting rod tip portion eyelet profile also easily departs from, this is with the exercise performance of unfavorable reciprocating machine, and consequently the performance to whole compressor impacts.
The utility model adopt to divide body structure, makes easy to assembly and is convenient to the manufacturing processing of connecting rod, eliminates the possibility that skew takes place connecting rod tip portion eyelet profile full circle degree.Simultaneously, because the connecting rod CONCENTRIC REDUCER is an integral body, machining accuracy is easy to guarantee.
Summary of the invention
The utility model will solve relatively difficulty of assemblings such as reciprocatable refrigerating equipment compressor connecting bar is connected with piston, need on cylinder block, open mount inlet and cause the sealing area of cylinder body and piston to reduce in advance when particularly connecting piston and connecting rod with pin, reduced the working efficiency of compressor, and the machining accuracy of using traditional subdivision connecting rod to bring is difficult.Simultaneously the surface of contact of connnecting rod big end and big skull easily deforms, and the full circle degree of connecting rod tip portion eyelet profile also easily departs from, the exercise performance of unfavorable reciprocating machine, the consequently problem that the performance of whole compressor is impacted.Reciprocatable refrigerating equipment compressor connecting bar of the present utility model is provided for this reason.This connecting rod adopts and divides body structure, make to sell and need not on cylinder body, to open mount inlet when connecting piston, effectively increased the sealing area of cylinder body and piston, improved the working efficiency of compressor, simultaneously easy to assembly and be convenient to the manufacturing processing of connecting rod, eliminate the possibility that skew takes place connecting rod tip portion eyelet profile full circle degree.In addition, because the connecting rod CONCENTRIC REDUCER is an integral body, machining accuracy is easy to guarantee.
Detailed says, the special way of the utility model connecting rod is to be cooperated by the connecting body of band major part and the band microcephaly connecting body that can be connected with the connecting body of described band major part and constitutes; One end of described band major part connecting body is provided with the major part that connects bent axle, and the other end is provided with groove; One end of described band microcephaly connecting body is provided with the microcephaly who connects wrist pin, and the other end is provided with plush copper, and the central axis of plush copper and connecting rod does not overlap, but the certain deviation amount is arranged; The size of the plush copper of the groove of band major part connecting body and band microcephaly connecting body is when two sections connecting bodys cooperate, and is concordant mutually at the outer circumferential face of two sections connecting bodys of join domain; The part that two sections connecting bodys match has the jump ring groove, with jump ring two sections connecting bodys is fixed during assembling.Design has a sign hole on two sections connecting bodys, so that assembling and avoid makeing mistakes.
