Abstract

The invention relates to a noise reduction type engine gear transmission system which comprises a crankshaft gear. The intake and exhaust sides of the crankshaft gear are engaged with two idle gears correspondingly, an air compressor gear is engaged with the exhaust side idle gear, and a fuel injection pump gear and a power steering pump gear are engaged with the intake side idle gear. Each idle gear includes a main gear and a secondary gear which are arranged on a bush, wherein the main gear and the secondary gear are each provided with a pin, a spring is arranged between the main gear and the secondary gear, and the main gear and the secondary gear are connected by the spring and the pins. The main gear and the secondary gear of the exhaust side idle gear are engaged with the crankshaftgear and the air compressor gear, the main gear and the secondary gear of the intake side idle gear are engaged with the crankshaft gear and the fuel injection pump gear, the main gear of the intake side idle gear is engaged with the power steering pump gear, and the secondary gear of the intake side idle gear is not engaged with the power steering pump gear. By means of the engine gear transmission system, the gap between gears can be effectively reduced or eliminated, gear noise is reduced, meanwhile, the structure is compact, the cost is low, and the requirements that an engine is low in cost and noise and a fuel injection pump cannot bear axial force are met.

Description

technical field [0001] The invention relates to an engine gear transmission system, in particular to a noise reduction engine gear transmission system, which belongs to the field of engines. Background technique [0002] With the increasingly stringent national emission regulations and the rapid development and application of engine electronic control fuel injection common rail technology, many high-pressure oil pumps cannot withstand axial force, which puts forward higher requirements for engine transmission systems, especially gear transmission systems. [0003] In order to solve this problem, the traditional engine gear transmission system generally adopts two solutions: [0004] One is to use spur gears for the fuel injection pump end gears, and use helical gears for the rest of the gears, that is, use one row of spur gears and one row of helical gears and two rows of gears to solve the problem. [0005] The other is that all spur gears are used, and the idle gear adopt...
