Design of A New Engine Transmission Mechanism Based on Gears and Racks

Abstract

Abstract.A new type of engine transmission mechanism based on gears and racks is introduced,which is mainly composed of a pair of incomplete gears with overrun clutch, a composite rack and a bevel gear train.With the interval meshing of incomplete gears with composite rack, the reciprocating linear motion of piston is transmitted and eventually converted to continuous and rotational movement by the bevel gear train.Compared with traditional crank-connecting rod mechanism, the new drive mechanism performs with higher transmission efficiency, more stable power output and lower vibration noise.
