“…A spring model for sprocket-chain load distribution was studied and then compared with traditional forcebalance analysis in the work of [7]. Important facts were discussed about the pitch difference and its effect on the contact point that appears between the bushes of a bush chain with the chain sprocket [8]. These works contributed to a better understanding of the forces distribution and contact point position variation in case of bush and roller chains.…”

Silent chains tend to have more and more usage in automotive industry. The study of these types of chains has a lot to consider due to the fact that silent chains are not standardized yet. The aim of this paper is to study and analyse the theoretical contact point between a silent chain’s toothed plate and an involute sprocket. Varying different parameters of the chain and sprocket, there will be studied its effects on the theoretical contact point and the sprocket’s profile geometry.

“…The paper propose a kinematic modelling algorithm for the contact angle between the bush and the chain wheel which produces a variable angle dependent on the chain's specific elongation (x) and on the bushes number being in contact (i). This algorithm is an add-on to the kinematic modelling proposed by the authors which is referring on the kinematics of the chain links displacement depending on the wheel's rotation angle [5] and on the chain's specific elongation and teeth's number [6].…”

The chain drive transmissions are used mainly in the automotive industry as distribution transmissions in cars. In the specific literature, the kinematics and the dynamic analysis problems are accomplished depending on the European and American standards. The contact between the chain’s bush and the chain wheel is influencing the transmissions dynamics and is influenced directly by its geometry. According to these, the paper presents the influence of the chain wheel’s geometry on the contact angle which depends on the point’s position where the normal and transversal forces are acting.
