Abstract

The invention relates to a cam follow-up device of an engine, comprising a follow-up body, a roller and a roller pin, wherein one end of the follow-up body is connected to an engine cylinder body through a mounting shaft arranged in a mounting shaft through hole, the lower part of the other end of the follow-up body is provided with a roller mounting slot, and the roller is arranged in the rollermounting slot through the roller pin. The device is characterized in that the upper part of the other end of the follow-up body is fixedly provided with a ball socket base, and the upper end surface of the ball socket base is concavely provided with a ball socket groove matched with the ball end surface of a push rod; the ball socket base is provided with an axial through hole, a radial hole and an inclined hole; the axial through hole is communicated with a first oil containing hole and communicated to the roller mounting slot; the radial hole is communicated with a second oil containing hole and communicated to the inner wall of the mounting shaft through hole; and the inclined hole is communicated with a third oil containing hole and communicated to the inner wall of a roller pin mounting hole as well as communicated to an oil containing tank through a radial straight oil hole and an inclined oil hole. The invention has the advantages of artful and reasonable structure, excellent property, wear resistance, high pitting corrosion resistance, good lubricating property and long service life.

Description

technical field [0001] The invention relates to a device for controlling the opening and closing of intake and exhaust valves of an automobile engine, in particular to a cam follower suitable for high-horsepower engines. Background technique [0002] The gas distribution mechanism is the "control center" of the engine. Whether the engine is running normally or not, the gas distribution mechanism plays a very critical role. The valve mechanism of the engine mainly includes parts such as camshaft, cam follower, push rod, rocker arm, intake valve, exhaust valve, valve spring, valve guide, spring seat and T-shaped pressure plate. intake and exhaust. When the gas distribution mechanism is working, the crankshaft drives the camshaft, and the camshaft drives the cam to rotate. When the cam moves to the highest point, the highest point of the cam contacts the roller in the cam follower, thereby bringing the entire cam follower to the highest position. At this point, the cam follow...
