Piston crankshaftless engine

Abstract

The invention discloses a kind of piston engine without crank, a power converting mechanism made up of mobile gear, gear rack connected to the piston and the driving gear fixed on the straight output main shaft replaces traditional crank link mechanism, and it overcomes the deficiency of current crank-less engine; the mobile gear can move between the connection position and the non-connection position, thus the dynamic force device between the gear rack and the driving gear can be in on / off state; in the exposure distance of the piston, it can transmit force to the main shaft through the force transmitting chain; the back movement of piston doesn't affect the movement of the output main shaft; along with the joining movement of mobile gear, by mating with the other assistant system, the reciprocate straight movement can be changed into the power output with continuous single direction rotation of main shaft. The converter can be used in gasline, diesel, gas inner combustion machine.

Description

technical field [0001] The invention relates to piston engines, including gasoline, diesel, gas and other internal combustion engines, as well as piston steam engines, etc., especially to piston engines without a crankshaft. Background technique [0002] Present piston engines include internal combustion engines such as gasoline, diesel oil, and gas, and steam engines. [0003] Its biggest defect is that the mechanical power conversion efficiency is greatly limited, because when the cylinder burst pressure P is the largest, that is, when the piston is near the top dead center, the component force P of the cylinder pressure P in the direction of the connecting rod 1 Although the largest at this time, but due to P 1 The force acting on the crankshaft is almost directly facing the rotation axis of the crankshaft, but its force arm is the smallest, that is, the rotational moment is the smallest; with the rotation of the crankshaft, although t...

AI Technical Summary

Problems solved by technology

Its shortcoming is that there is a dead point, and the alignment between the rack and the semicircular gear is very demanding. When the engine speed changes in a large range, there may be misalignment, and once misalignment occurs, it may occur. have more serious consequences

Its shortcoming is that the overrunning clutch is a relatively precise device, and its service life is directly related to the impact force, clutch frequency, frequency, etc., which may be greatly restricted in practical applications.
