Problems solved by technology

Its shortcoming is that, because the clutch internal tooth assembly inevitably swings during the movement process, the connecting rod also swings accordingly, so the connection between the connecting rod and the main working piston cannot be fixed, but only hinged, so it cannot be connected A sealing ring is set on the rod, so that the space between the back of the piston and the cylinder cannot be air-tight and cannot be used. The additional auxiliary piston, although the direct shaft drive is realized, the meshing of the transmission gear and the transmission rack is due to The swing of the inner tooth assembly is not reliable, and there are two abrupt steps on the arc-shaped convex edge of the rever

Embodiment 1

[0042] Figure 6 to Figure 9 Shown is a two-stroke dual opposed piston engine. Taking the axis of the main shaft 10 as the reference center, the piston close to the axis is called the "inner piston", and the piston farther from the axis than the "inner piston" is called the "outer piston". Similarly, the axial connecting rod fixedly connected to the "inner piston" is called the "inner axial connecting rod", and the axial connecting rod fixedly connected to the "outer piston" is called the "outer frame-shaped axial connecting rod".

Abstract

The invention discloses a shaft type connecting rod transmission system and an opposed piston engine; and a traditional reciprocating linear motion is converted to a rotating motion in the same direction, so that the reliability of the transmission system is effectively improved, the transmission system is simplified to become more compact, and effective utilization of a space between the back surface of a piston of an internal combustion engine and a cylinder becomes possible. The shaft type connecting rod transmission system comprises a main shaft and at least one linear reciprocating motion unit, wherein the linear reciprocating motion unit comprises at least one linear reciprocating motion body. The linear reciprocating motion bodies are fixedly connected with one ends of corresponding shaft type connecting rods; the other ends of the shaft type connecting rods are fixedly connected with one sides of corresponding push-pull frames; and the axles of the shaft type connecting rods and the main shaft are perpendicular to each other. Slip blocks are arranged in the push-pull frames; two transverse outer side walls of the slip blocks and two transverse inner side walls of the push-pull frames are formed to vertical slide fit; inner rings of the slip blocks have inner teeth with elliptic indexing circles; and the inner teeth are circularly engaged with gears correspondingly arranged on the main shaft. Reversing mechanisms are arranged between the main shaft and the slip blocks.

Description

Technical field [0001] The invention relates to a shaft type connecting rod transmission system that converts linear reciprocating motion into rotation motion, and an opposed piston engine adopting the shaft type connecting rod transmission system. Background technique [0002] At present, the most popular piston engine is the crankshaft connecting rod piston engine. The crankshaft connecting rod mechanism converts the linear reciprocating motion of the piston into the crankshaft rotary motion, but the crank connecting rod mechanism reduces the efficiency of the piston engine and the fuel utilization efficiency Only about 30%. [0003] In order to improve the efficiency of the piston engine, the structure of the piston engine and its transmission system have been continuously improved. [0004] For example, in the invention patent application specification with the publication number CN102003282, an internal rack-and-pinion linkage mechanism for the external gear shaft of an engine ...
