A shaft connecting rod transmission system and an opposed piston engine

Abstract

A shaft connecting rod transmission system and an opposed piston engine to convert reciprocating linear motion into rotary motion in the same direction, effectively improve the reliability of the transmission system, simplify the transmission system to make it more compact, and make the piston on the back of the internal combustion engine It is possible to effectively use the space between the cylinder and the cylinder. The shaft link transmission system includes a main shaft and at least one rectilinear reciprocating unit, and the rectilinear reciprocating unit includes at least one rectilinear reciprocating body. The linear reciprocating body is fixedly connected to one end of the corresponding shaft connecting rod, the other end of the shaft connecting rod is fixedly connected to one side of the corresponding push-pull frame, and the axes of the shaft connecting rod and the main shaft are perpendicular to each other. A sliding block is arranged in the push-pull frame, and the two lateral outer walls of the sliding block form a vertical sliding fit with the two lateral inner walls of the push-pull frame. The teeth are cyclically meshed with the gears correspondingly arranged on the main shaft. A reversing mechanism is arranged between the main shaft and the sliding block.

Description

technical field [0001] The invention relates to a shaft type connecting rod transmission system which converts linear reciprocating motion into rotary motion, and an opposed piston engine adopting the shaft type connecting rod transmission system. Background technique [0002] The most popular piston engine is the crankshaft connecting rod piston engine. The linear reciprocating motion of the piston is converted into the rotary motion of the crankshaft through the crankshaft connecting rod mechanism, but the crankshaft 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, people are constantly improving the structure of the piston engine and its transmission system. [0004] For example, in the invention patent application specification with the publication number CN102003282, a kind of engine external pinion internal rack linkage mechanism i...

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 reversing mechanism, which will cause greater impact, mechanical wear and noise to the left and right baffles, and the reliability of the operation cannot be guaranteed

Obviously, the gear transmission mechanism has the following deficiencies. Two sets of gear sleeve components must cooperate with each other to complete the reversing operation of the internal teeth. The corresponding piston and gear sleeve components must also be two sets and cannot be operated independently; the mechanism More parts will increase the inertial mass, which will have a negative impact on its operating efficiency; the limit mechanism is too complicated, which will increase manufacturing costs and reduce reliability and stability
