Engine body of crank round slide block or end shaft-moving shaft mechanism as well as internal combustion engine and compressor

Abstract

The invention provides an engine body of a crank round slide block or an end shaft-moving shaft mechanism, which comprises runway installing through holes for installing dynamic balance slide block runways, runway installing seats are fixedly arranged on the end surfaces of two hole ports of the runway installing through holes, and a first fixed structure is arranged on the runway installing seats; and the engine body also comprises a pair of independently made runways, the opposite inner surfaces of the installed runways are sliding rail surfaces for reciprocating motion of dynamic balance slide blocks, both ends of the runways are provided with a second fixed structure corresponding to the first fixed structure, the second fixed structure and the first fixed structure are connected by aconnecting piece, and the runways can be symmetrically installed in the runway installing through holes. As the slide rail surfaces with high processing requirements are arranged on the independentlymade runways, the engine body provided in the invention is convenient for high-precision processing. The invention simultaneously provides an internal combustion engine and a compressor using the engine body.

Description

technical field [0001] The invention relates to an internal combustion engine body, in particular to the body of a crank circular slider or an end shaft-moving shaft mechanism. The present invention also provides an internal combustion engine and a compressor using the above body. Background technique [0002] The internal combustion engine block needs to provide kinematic support for the various moving components. In the body that adopts the crank circular slider or the end shaft-moving shaft mechanism, there is a special moving element of the dynamic balance slider, and the body needs to provide a reciprocating track for the dynamic balance slider, which is called a runway or a slideway. [0003] In the dynamic balance slider provided in the prior art, the dynamic balance slider is generally a flat body, and its running track is a flat through hole. figure 1 , figure 2 The compressor body provided by Beijing Zhongqingneng Engine Technology Co., Ltd. with the applicatio...

AI Technical Summary

Problems solved by technology

[0004] The problem with the above body is that, in the crank circular slider or end shaft-moving shaft mechanism, the reciprocating and rotating parts must maintain a strict phase relationship during the movement process, which requires the body to provide reciprocating motion The track and the position of the rotating support maintain a strict spatial relationship with each other, which reflects very strict requirements on the shape and size tolerances and dimensional tolerances of each part of the body in terms of technology.

In the above-mentioned body, the runway 01 adopts a flat structure, and the surface of the slide rail cannot be processed with a rotating tool in the usual method of processing a cylindrical surface. It is more difficult to process, and it is even more difficult to obtain high-precision shape and position tolerances or dimensional tolerances.

In fact, even if the runway 01 adopts a cylindrical through hole, its processing is very difficult due to the high requirements on the surface accuracy and roughness of the runway
