Abstract
The utility model relates to a timing chain, in particular to a wear-resistant engine timing chain, which comprises a chain body. The chain body is formed by interconnecting chain links; a chain link comprises external chain plates, an inner chain plate, a pin shaft and a sleeve; the two ends of the pin shaft are respectively provided with an outer chain plate; the inner chain plate is in contact connection with the inner wall of the outer chain plate; and the sleeve is sleeved outside the pin shaft. The operating stability of an automobile is improved and the chain jumping caused by high-speed operation is reduced, so that the anti-fatigue performance of the chain, the tensile strength and the accuracy for controlling the length of the chain are favorably improved, and the service life is prolonged.
Description
Technical field
The utility model patent relates to a kind of timing chain, relates in particular to wear-resisting engine timing chain.
Background technique
Be used for the chain on the motor car engine at present, select BIN standard chain 06B series substantially for use, its structural type is roller chain, and structure is made up of outer plate, bearing pin, inner plate, sleeve and five parts of roller substantially; The automobile chain is the Transmitted chains of engine interior from the bent axle to the camshaft, being used to finish the engine piston stroke cooperates with the strictness of steam discharge time, work under enclosed oil sump lubricating condition, rotating speed is all having very high requirement up to 5000r/min aspect precision, shock resistance, wear resistance, the stationarity.The 06B standard chain of selecting for use at present all exists certain defective, especially roller aspect shock resistance, wear resistance, the stationarity, it is cracked easily down to run up at chain.Cause chain low working life.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of and can satisfy the automobile chain and run up, and has improved the wear-resisting engine timing chain of wear resistance simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of wear-resisting engine timing chain comprises serobila, and described serobila is formed by connecting by chain link, described chain link comprises outer plate, inner plate, bearing pin and sleeve, the two ends of described bearing pin are respectively equipped with outer plate, and inner plate touches mutually with the inwall of outer plate, and described bearing pin is with sleeve outward.This structural design can more can satisfy the stability that the automobile chain runs up, and reduces beating of being produced when chain runs up.
As preferably, described inner plate is sleeved on the sleeve, and the end face of sleeve and outer plate inner side surface offset.
As preferably, described sleeve is the low-carbon alloy steel part.Improve whole chain tensile strength, prolong chain working life, can improve wear-resisting property like this, reduced the sleeve wall thickness difference simultaneously, guarantee concentricity, make chain transmission more steady.
Therefore, wear-resisting engine timing chain of the present utility model has improved the stability of automobile runs, has reduced beating of being produced when chain runs up; Help improving the anti-fatigue performance of chain, tensile strength, control chain length precision increase the service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
