Novel transmission mechanism for single-cylinder engine

Abstract

The invention relates to a novel transmission mechanism for a single-cylinder engine. Torque is transmitted upwards to a fixed high-pressure pump gear train 3 and a fixed distribution gear train 4 by a fixed crankshaft gear 1 through a first idle gear 2, the torque is transmitted downwards to a second balance gear train 5, a second balance gear 6, a first balance gear train 10 and a first balance gear 9 by the fixed crankshaft gear 1 through a second idle gear 8 and a third idle gear 7 to realize oil burning of the single-cylinder engine and rotation of a distribution camshaft, and the balance gear trains drive balance shafts to rotate to eliminate unbalance of the whole engine. By the aid of the novel transmission mechanism for the single-cylinder engine, the positions of the distribution gear train and an oil supply gear train can be adjusted, so that whole arrangement of the single-cylinder engine can be adjusted, test requirements of a plurality of series of texturing machines are met, the use ratio of the single-cylinder engine is increased, research cost is reduced, a severe working environment of a balance shafting splashing inside an engine block is changed, the height of the whole engine in general arrangement is reduced, the overturning moment resistance of the single-cylinder engine is enhanced, and working stability is enhanced.

Description

technical field [0001] The invention belongs to the field of gear transmission, and in particular relates to a novel single-cylinder engine transmission mechanism. Background technique [0002] The basic composition of the single-cylinder gear transmission mechanism includes crankshaft gear, gas distribution gear train, oil supply gear train, balance gear train and so on. The crankshaft gear provides working torque for the transmission mechanism and is the driving gear; the gas distribution gear train drives the gas distribution gear to complete the camshaft rotation and valve opening and closing; the oil supply gear train drives the high-pressure oil pump to provide fuel supply for the whole machine; the balance gear The system drives the balance shaft to rotate to eliminate the unbalance of the whole machine. The crankshaft gear transmits the torque to the oil supply gear train and the gas distribution gear train through an idler gear upwards, and transmits the torque to...

AI Technical Summary

Problems solved by technology

The crankshaft gear transmits the torque to the oil supply gear train and the gas distribution gear train through an idler gear upwards, and transmits the torque to the balance gear train downwards through an idler gear at a specified speed. The advantage is that the transmission arrangement is simple, the structure is compact, and the gears The quantity is small, and the transmission noise is low; the disadvantage is that the special machine is dedicated, the mechanism adjustment ability is poor, and the multi-series application is difficult

This arrangement makes the crankcase and the balance chamber the same chamber, the oil is easy to splash, the environment is harsh, and the exhaust gas pressure of the whole machine is high
