Abstract

The utility model relates to a bearing type multiple cylinder eccentric shaft which is characterized in that some eccentric rolling bearings are mounted on a long straight shaft in conformity to the parameters of the dimensions of eccentricity of the crank, each eccentric rolling bearing consists of a rolling bearing, an inner race shaft disk, a stop collar groove and an eccentric hole of elastic stop collar. The inner race shaft disk is embedded in the inner race shaft hole of the rolling bearing, the bottom of the flange of one end of the inner race shaft disk is pressed against the inner race of the rolling bearing to match the position of the other end surface of the inner race of the rolling bearing, a stop collar groove is cut at the other end of the inner race shaft disk, an elastic stop collar is mounted in the stop collar groove to keep the inner race shaft disk in the inner race of the rolling bearing, and an eccentric hole is cut on the surface of the inner race shaft disk according to the dimensions of the eccentricity to fix the long straight shaft in the eccentric hole. The utility model, is simple and compact in structure, is convenient to produce and install, saves time and labor, can replace the crank, and has the advantages of good performance in abrasion resistance, low production cost and convenient application.

Description

The biased axle of bearing type multi-cylinder

Technical field

The utility model belongs to a base part, and specifically, it relates to substitute the biased axle of a kind of bearing type multi-cylinder of bent axle.

Background technique

As everyone knows, bent axle is widely used as the vitals of various engineering goods, as internal-combustion engine, diesel engine, steamer etc., but its processing technology complexity, both need be with special-purpose lathe and worker, jig, and its requirement on machining accuracy height again, amount of finish is big, is difficult to operation; Cause taking a lot of work, effort is taken material, increases manufacture cost; And the bent axle after the processing, also need to carry out comparatively complicated heat treatment, in case it is bad as each Working Procedure Controlling, will make each mechanical performance index, the metallographic structure of bent axle not meet standard-required, when serious, even make the bent axle after the heat treatment produce fracture, thereby the bent axle that causes after the processing is scrapped; In addition, on the bent axle after qualified, also need be equipped with members such as connecting rod, bearing shell, lubricated oil box, this moment, bent axle and bearing shell will produce friction in high speed rotating, though when proper functioning, have lubricated oil box to provide lubricant oil to be lubricated, but in case lubricated oil box leakage of oil, in time do not find again, maintenance or operate miss regularly do not replenish and change lubricated oil box, will generate heat because of the friction of bent axle and bearing shell, consequently improve temperature and cause bent axle, bearing shell to burn to scrap.

Summary of the invention

The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only simple in structure, compact, both be convenient to install and made, save labor, alternative again bent axle, and it is good to have wear resistance, low cost of manufacture and the biased axle of a kind of very easily bearing type multi-cylinder of use.

The purpose of this utility model is to adopt following technological scheme to realize: the biased axle of bearing type multi-cylinder, it is characterized in that: corresponding with the throw of eccentric dimensional parameters of bent axle, on a long straight shaft, adorn several eccentric rolling bearings to install the mode string, described each eccentric rolling bearing is by rolling bearing, the inner ring reel, circlip groove, the circlip eccentric opening is formed, in the inner ring axis hole of rolling bearing, inlay affixed inner ring reel, make the flange bottom surface of inner ring reel one end be close to the inner ring of rolling bearing, corresponding with the position, inner ring other end of rolling bearing, on the other end of inner ring reel, be processed with circlip groove, the circlip of packing in the circlip groove, the inner ring reel is fastened in the inner ring of rolling bearing, size according to throw of eccentric, in inner ring reel face, be processed with eccentric opening, long straight shaft is fastened in the eccentric opening.Described rolling bearing, common ball bearing and cylindrical bearing based on single, double row ball entad.Described affixed mode can be divided into machinery and head into formula, forced, the cold stationary of hot charging of hydraulic press; Also can adopt the key jointing type.Combine the above technical measures of being taked, realize the purpose of this utility model.

Compared with prior art, the utility model is not only simple in structure, compact, both has been convenient to install to make, and saves labor alternative again bent axle, and it is good to have wear resistance, low cost of manufacture and use advantages such as very convenient.
