Problems solved by technology

The service life of the chain is long, but the chain transmission noise is large, and it is generally used for small displacement engines, such as motorcycle engines
The output power of the engine is related to the rotation speed. The current development direction is high speed, high power and light weight. Compared with the medium and low speed engine, the timing belt of the high speed engine is more easily damaged, and the noise of the chain is louder, so the requirements for the transmission components are higher. There are currently no long-life, low-noise transmission components

Embodiment Construction

[0011] combine figure 2 and image 3 , the chain part of the embodiment is composed of chain pieces 3 and pins 4 connecting each chain piece 3, and each chain is composed of parallel chain pieces 3, and there are four pieces and five pieces respectively, and the chain pieces between adjacent chains of each section 3 are staggered and embedded, connected in series with pins 4, and the inner side of the chain sheet 3 is shaped on an involute sprocket, and this structure is the same as the existing timing chain.

[0012] combine figure 1 and figure 2 , the chain is embedded in the rubber belt 1, and is made as a whole with the rubber belt 1, the tooth surface of the sprocket is flat with the inner tooth surface of the rubber belt 1, and the cord 2 is embedded in the outer position of the chain in the rubber belt 1.

[0013] ·The rubber belt is made of NBR or Viton, and the chain piece 3 is made of iron plate.

[0014] After the chain is embedded in the rubber belt, rubber i...

Abstract

The present invention discloses a engine mute return chain including chain pieces chained in series and dowel used to connect each chain piece; each segment of chain is combined by chain piece in parallel and each chain piece of adjacent chains interleaving embedded and connected by the dowels; involutes sprocket is provided on the inner side of the chain piece; the chain is embedded in the rubber belts with the rubber belts in a whole; flank of tooth of the sprocket in same level with gear form of the rubber belts; cord yarn is provided on external side of the chain inside rubber belts. The material of rubber belts adopts NBR or fluorubber. Because the chain and the rubber belts are made as a whole, noise can be reduced, and the invention is in long service life without easy stretch and fracture.

Description

technical field [0001] The present invention relates to engine components, particularly improvements to timing chains. Background technique [0002] In the engine, there are two types of transmission devices between the crankshaft and the camshaft: timing belt and chain. Timing belt transmission has the advantages of small gap, accurate transmission, large transmission torque, and low noise. Automobile engines mostly use timing belt transmission. Timing belts are easy to wear and need to be replaced after a certain period of use. The service life of the chain is long, but the chain transmission noise is large, and it is generally used for small displacement engines, such as motorcycle engines. The output power of the engine is related to the rotation speed. The current development direction is high speed, high power and light weight. Compared with the medium and low speed engine, the timing belt of the high speed engine is more easily damaged, and the noise of the chain is ...
