Problems solved by technology

In the engine with camshaft bottom structure, because the rocker arm and rocker shaft are at the far end of the engine, the oil pressure supply is insufficient, which can only meet the lubrication at the push rod and rocker ball socket, while the rocker arm and rocker shaft move The place is not lubricated, resulting in eccentric wear of the rocker shaft and the rocker arm, and eventually failure

Abstract

The invention discloses an engine valve rocker arm installation structure, comprising an engine cylinder head and a rocker shaft, the rocker shaft is rotatably arranged on the engine cylinder head, and the rocker shaft has a function for receiving The annular oil groove of the lubricating oil of the cover, the oil inlet hole communicated with the annular oil groove, the axial oil channel communicated with the oil inlet hole, and the first part communicated with the axial oil channel and used to guide the lubricating oil to the first rocker arm installation area An oil outlet hole and a second oil outlet hole communicated with the axial oil passage and used to guide lubricating oil to the second rocker arm installation area, the annular oil groove is located between the first oil outlet hole and the second oil outlet hole, the shaft The oil passage extends axially along the rocker arm shaft, and the first rocker arm installation area and the second rocker arm installation area are used to respectively install a valve rocker arm. The installation structure of the engine valve rocker arm of the present invention satisfies the condition of forming an oil film between the rocker arm shaft and the valve rocker arm, can effectively reduce wear between the rocker arm shaft and the valve rocker arm, and can significantly improve the oil supply efficiency.

Description

technical field [0001] The invention belongs to the technical field of engine parts, and in particular, the invention relates to an engine valve rocker arm mounting structure. Background technique [0002] In the engine with the camshaft bottom structure, the rocker arm shaft is similar to the lever fulcrum, and its main function is to support the rocker arm to open the valve. The traditional rocker arm shaft is fixed by bolts or shaft seats, and the center hole of the rocker arm is connected to the rocker arm shaft. With clearance fit, the rocker arm rotates back and forth at high speed on the rocker arm shaft. The lubrication method between the rocker shaft and the rocker arm is as follows: the oil flows from the oil passage of the cylinder block through the hydraulic tappet and then goes up the center hole of the push rod, and then the oil is supplied from the push rod to the ball socket of the rocker arm. The center hole of the rocker arm is connected, and the oil can b...
