Problems solved by technology

On an opposed two-stroke diesel engine with a rocker arm structure, the cylinder is placed horizontally at a certain distance above the crankshaft and parallel to the horizontal plane of the crankshaft. The lower connecting rod is required to connect the crankshaft and the rocker arm. The traditional connecting rod cannot meet the requirements.

Embodiment Construction

[0013] Such as figure 1 , 2 As shown, a connecting rod of a two-stroke diesel engine with opposed pistons, which includes: connecting rod cover 1, connecting rod bolt 2, positioning sleeve 3, bearing bush 4, connecting rod 5, rocker arm lower pin 6, bolt assembly 7, nut 8. Bolt 9; one end of the connecting rod 5 is the small head side, and the other end is the big head side. The small head side is set as a fork-shaped structure with a U-shaped middle opening, and a process protrusion is arranged inside the fork-shaped structure. At the same time, the rocker arm lower pin 6 is set in its fork-shaped structure, the rocker arm 13 is installed in the U-shaped structure through the rocker arm lower pin 6, and the outer side of the rocker arm lower pin 6 has a 3mm through groove, which is convenient for rocking The lower pin 6 of the arm is loaded and pressed; the upper and lower parts of the through groove are provided with through holes for installing the bolt 9 and the nut 8, an...

Abstract

The invention relates to a connecting rod of a two-stroke diesel engine with opposed pistons. One end of the connecting rod (5) is a small-end side while the other end per se is a big-end side; the small-end side is set into a fork structure with a U-shaped middle hollow part; the fork structure is internally provided with a rocker arm lower pin (6); a rocker arm (13) is mounted in the U-shaped structure through the rocker arm lower pin (6); and the big-end side is internally provided with a bearing bush (4) which is connected with a crank pin of a crankshaft. The connecting rod of the two-stroke diesel engine with the opposed pistons, disclosed by the invention, has the advantages of realizing the purpose of connecting the crankshaft with the rocker arm and realizing power output as the small end of the connecting rod adopts a U-shaped structural design with the hollow middle part, and the rocker arm is mounted in the U-shaped small end through the rocker arm lower pin, simplifying the connecting rod structure, strengthening coupling stiffness and lowering reciprocating inertial force.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a connecting rod of an opposed-piston two-stroke diesel engine. Background technique [0002] The connecting rod is an important part of the engine, which is responsible for converting the linear reciprocating motion of the piston into the rotary motion of the crankshaft. On an opposed two-stroke diesel engine with a rocker arm structure, the cylinder is placed horizontally at a certain distance above the crankshaft and parallel to the horizontal plane of the crankshaft. The lower connecting rod is required to connect the crankshaft and the rocker arm, and the traditional connecting rod cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a connecting rod of an opposed-piston two-stroke diesel engine, which can smoothly connect the crankshaft and rocker arm of ...
