An automatic oil supply rocker arm fixing seat group and its implementation method

Abstract

The invention discloses a rocker arm fixing seat group for automatic oil supply and its implementation method, which belongs to the technical field of rocker arm fixing seat groups, and includes a rocker arm assembly, a drive assembly, a fixed shell and an oil supply assembly. The drive assemblies are connected to each other, and the drive assemblies are fixedly connected to the fixed housing. The rocker arm assembly includes a main rocker, an auxiliary rocker, a countershaft, an auxiliary gear, a main shaft, a right main gear, a left main gear, a chain and The front end of the main rocker is rotatably connected to the auxiliary rocker through the bearing, the auxiliary shaft is welded on one side wall of the auxiliary rocker, the lower end of the main rocker is fixedly connected to the main shaft, the main shaft and the main shaft The middle part of the rocker is provided with a flow channel, and the flow channel is connected with the oil supply assembly. The oil introduction assembly is arranged in the assembly gap of the shaking mechanical parts, and the oil supply is provided with the shaking, which simplifies the oil supply structure. The cavity in the middle of the bearing will not cause excessive oil, and the oil supply assembly will not be affected by the mechanical operation.

Description

technical field [0001] The invention relates to the technical field of the rocker arm fixing seat group, in particular to an automatic oil supply rocker arm fixing seat group and its implementation method. Background technique [0002] The rocker arm occupies an important position in the mechanical structure. The performance of the rocker arm is affected by lubrication. Insufficient lubrication can easily lead to wear at the joints and affect the accuracy and smoothness of the rocker arm swing. Therefore, it is necessary to supply oil to the rocker arm. [0003] The patent No. CN201220569267.9 discloses a rocker shaft oil supply mechanism, which includes a rocker arm, a rocker shaft and a rocker shaft seat. There is a shaft hole on the side of the rocker arm, and the rocker shaft is inserted into the shaft hole and connected with the rocker arm in rotation, the rocker arm shaft seat is provided with two pillars, the top surface of each pillar is a concave arc surface, the ro...

AI Technical Summary

Problems solved by technology

However, the oil supply structure of this patent is complicated, and the oil supply structure is greatly affected by the mechanical operation on the rocker arm. If the operating speed and amplitude of the rocker arm are too large, the oil supply will be large, and if the operating speed and amplitude of the rocker arm are too small, the oil supply will be too large. However, the amount of oil required at the joint is also affected by the wear condition of the joint and the amount of oil absorbed by the surface of the parts, so the oil is easily excessive, and the excess oil cannot be recovered or transferred in time, and for multi-rod rocker arms, it cannot continuous oil supply
