Simple gear transmission timing alignment mechanism and operation method thereof

Abstract

The invention discloses a simple gear transmission timing alignment mechanism and an operation method thereof. The simple gear transmission timing alignment mechanism is used for assembling a timing gear system, and the simple gear transmission timing alignment mechanism at least comprises an idle gear, a first positioning through hole is formed in an anti-attrition face or anti-attrition plate onan idle gear shaft, a first blind hole is formed on the corresponding timing position of the idle gear, when the idle gear is aligned with a crankshaft timing gear or a first gear which is assembledfirstly, the first positioning through hole can correspond to the position of the first blind hole, a first positioning mechanism, the first positioning through hole and the first blind hole are positioned, and the idle gear is fixed. Through the simple gear transmission timing alignment mechanism, engine assembling ability can be greatly improved, timing gear assembling accuracy is improved, relative rotation happening after wrong assembly and assembly of the timing gear can be effectively prevented, and the wrong assembly of subsequent timing gears can be avoided.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a simple gear transmission pair timing mechanism and an operation method thereof. Background technique [0002] The gear train of the traditional gear drive timing system needs to be marked according to the timing marks on the gears when installing or maintaining the engine. Only when the marks are correct can the engine run normally. Serious failures such as broken pistons and rocker arms. And in the process of engine assembly and alignment, the crankshaft cannot rotate, because the phenomenon of a wrong tooth is prone to occur in the case of a small rotation angle of the crankshaft, if it rotates, it may cause the wrong tooth and produce the above-mentioned failure. There is also the possibility of misalignment due to misuse causing the crankshaft to turn. [0003] Specifically, the traditional timing system of gears generally adopts mark-to-point assembly. Generall...

AI Technical Summary

Problems solved by technology

Since the engine has crankshaft timing gears, idler gears, fuel injection pump gears, camshaft gears and other gears that need to be aligned, the entire assembly process is a relatively long assembly process, and it is difficult to keep the timing gears from rotating during the assembly process. It is not easy to be found after the engine rotates, and the assembly efficiency is low

like figure 1 As shown, there are timing marks on gear a 3, gear b 4, and gear c 5. During assembly, gear b 4 needs to be matched with the timing marks on gear a 3 and gear c 5, that is, gear a 3 Timing mark 6 and b gear 4 timing mark 7 need to be paired, and b gear 4 timing mark 8 and c gear 5 timing mark 9 also need to be paired, if after completing the assembly of a gear 3 and b gear 4, The gears are easy to rotate relative to each other. When c-gear 5 is paired with the marks on b-gear 4, there will be problems with the timing mechanism driven by c-gear 5, resulting in corresponding failures
