Abstract

The invention discloses an assistant mounting device for a camshaft of an engine and a mounting method. A first pin hole is formed in a timing gear of the camshaft. The assistant mounting device comprises an assisting part, a crankshaft vibration absorber and a positioning pin, wherein the assisting part is fixed to the top surface of a cylinder cover of the engine; a second pin hole is formed in the assisting part; the height difference between a central shaft of the second pin hole and the top surface of the cylinder cover is a preset height; the horizontal distance from the central shaft of the second pin hole to the central shaft of a crankshaft gear of the engine is a preset distance; the crankshaft vibration absorber is fixed to a crankshaft; a zero graduation line is arranged on the crankshaft vibration absorber; when the zero graduation line is positioned right above the crankshaft vibration absorber under a mounting state, a piston of a first cylinder of the engine is positioned at an upper stopping point, and the positioning pin synchronously passes through the first pin hole and the second pin hole. According to the device, other parts on the crankshaft cannot be dismounted and replaced additionally, so that the workload can be greatly decreased, the overhaul efficiency can be improved, and meanwhile, that other parts are dismounted additionally to cause the risk of leaking of each sealing surface can be avoided.

Description

technical field [0001] The invention relates to the field of engines, in particular to an auxiliary installation device and installation method for a camshaft of an engine. Background technique [0002] In the diesel engine industry, since the camshaft of the overhead camshaft engine is installed on the cylinder head, it is necessary to remove the camshaft during inspection and maintenance. Reassemble the camshaft after inspection and repair. Since there is a certain phase relationship between the camshaft and the crankshaft, when reinstalling the camshaft, the phase relationship must be correct, otherwise the engine will not work. [0003] The phase relationship between the camshaft and the crankshaft is guaranteed by the positional relationship between the camshaft timing gear fixed on the camshaft and the crankshaft gear fixed on the crankshaft. However, due to the distance between the camshaft and the crankshaft and the relationship between the rotation directions of t...
