Study on Join Fastness of Silent Chain

Abstract

In order to improve the join fastness of silent chain, a new silent chain assembly method is proposed. It increases the capability that the silent chain stands against transverse vibration, reduces the meshing noise of silent chain without changing the space size of silent chain, by replacing the installing of outer link plate and pin as a press-fit configuration, and taking wire lock on the joint. The result of extrusion force comparative experiment showed that the extrusion force of outer link plate press-fit configuration was 2.5 times than gasket press-fit configuration. Through the platform contrast test, a noise test of two types of silent chain were made at the same speed, the result showed that the new silent chain drive more smoothly than the traditional one, the average noise level was decreased by 1.5dB. The two test results verified that the new silent chain assembly method is validity.
