Problems solved by technology

[0004] Since the cylinder head 14 and the rocker arm shaft support 12 are processed separately and then assembled, there are many parts for auxiliary installation and positioning, the structure is not compact enough, the accessibility during maintenance is poor, and it is not easy to repair
In addition, the positioning of the rocker shaft support is also relatively cumbersome.

Abstract

The invention discloses a cylinder cover for a diesel engine. A rocker arm shaft (3) is inserted into a rocker arm shaft mounting hole of the cylinder cover (2) for the diesel engine; and an inlet valve rocker arm (5) and an exhaust valve rocker arm (6) are sleeved on the rocker arm shaft (3) respectively. According to the technical scheme, a rocker arm shaft support is integrated with the cylinder cover, so that the cylinder cover with the rocker arm shaft support is convenient to machine; and simultaneously, the cylinder cover has a compact and simple structure and is convenient to maintain, and a positioning process is not required in the process of assembling all the parts.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to a cylinder head of a diesel engine. Background technique [0002] The cylinder head 14 of the diesel engine is an important part of the diesel engine, and many parts in the valve train of the diesel engine must be attached to the cylinder head 14 for installation and use, such as figure 1 As shown, the valve transmission assembly in the valve train includes a rocker shaft 10, a rocker arm 11, a push rod (not shown in the figure), a tappet (not shown in the figure) and a camshaft (not shown in the figure) And other parts, the main function is to make the intake and exhaust valves (not shown in the figure) open and close according to the time specified by the gas distribution phase, and to ensure sufficient opening. Wherein, the rocker arm shaft 10 is a hollow shaft supported on the rocker arm shaft support 12, and the rocker arm 11 is a double-arm lever whose function is to change t...
