Abstract

The invention discloses a valve mechanism rocker arm mounting device. The rocker arm mounting device comprises an air inlet rocker arm shaft, an air inlet rocker arm shaft seat for supporting a firstend of the air inlet rocker arm shaft, an exhaust rocker arm shaft and an exhaust rocker arm shaft seat for supporting two ends of the exhaust rocker arm shaft, wherein the exhaust rocker arm shaft seat is provided with a first shaft hole and a second shaft hole, two ends of the exhaust rocker arm shaft are inserted into the first shaft hole and the second shaft hole respectively, an exhaust rocker arm is located between the first shaft hole and the second shaft hole, the air inlet rocker arm shaft seat is provided with a third shaft hole for allowing the first end of the air inlet rocker armshaft to be inserted, the second end of the air inlet rocker arm shaft is provided with a flange used for axially limiting an air inlet rocker arm, and the air inlet rocker arm is located between theflange and the third shaft hole. According to the valve mechanism rocker arm mounting device, the air inlet rocker arm is mounted on the rocker arm shaft through a cantilever structure, the exhaust rocker arm shaft penetrates through the exhaust rocker arm and then is mounted on the rocker arm shaft seat in a two-end supporting mode, the structure is compact, the occupied space is small, and the strength of the exhaust rocker arm mounting structure is high. The invention further discloses an aviation piston engine.

Description

technical field [0001] The invention belongs to the technical field of engines, in particular, the invention relates to a rocker arm installation device of a gas distribution mechanism and an aviation piston engine. Background technique [0002] The gas distribution mechanism is one of the two key mechanisms on the piston engine. The gas distribution mechanism is the control mechanism for intake and exhaust. The cylinder supplies combustible gas mixture (gasoline engine) or fresh air (diesel engine) and discharges exhaust gas in time to meet the intake and exhaust requirements of the engine. Through reasonable intake and exhaust timing design, the performance requirements of the engine are met. The rocker arm is the key part to transmit the driving force to drive the valve. According to the arrangement of the valve train, there are many structures and arrangements of the rocker arm. [0003] The used rocker arm of the existing aviation piston engine has a fully floating ind...
