Silent chain is widely used in the field of mechanical transmission. Compared with ordinary chain transmission, it has prominent advantages such as high precision, low noise, and being suitable for high speed and heavy loads. Based on the design concept of intelligent dynamics, the phase variation is carried out. The multiphase transmission silent chain retains the original advantages of the single-phase transmission silent chain, and its structure bearing capacity is improved, the polygon effect is reduced, and the fluctuation, noise, and vibration of elastic edge are improved. Based on rigid-flexible intelligent dynamics technology, the transmission characteristics of a multiphase transmission silent chain system were studied. In this paper, the meshing contact force between the chain plate and the sprocket is described in detail, and the 3d model and dynamic model of the multiphase transmission silent chain are established. Topological optimization method was used to design the lightweight of the multiphase transmission silent chain, and the existing target of lightweight was realized. The dynamics simulation was carried out to extract the dynamics data and analyze the dynamics characteristics such as tight edge fluctuation, instantaneous transmission ratio, and meshing contact force. The results show that the model correctly predicts the dynamic behavior of the system, and the high speed inhibits the lateral fluctuation of the system. The peak value of meshing contact force increases with the increase of rotational speed, and the multiphase drive can be used in practical control system design.

“…3,4 Gear couplings are used to meet the misalignment compensation capacity by weakening the load-carrying property, especially under the effect of misalignment, the mechanical properties of the tooth surface are very poor, and wear performance and load-carrying capacity decreases with the increase of misalignment angle. 5 The contact and load distribution of tooth have always been favored by researchers. 6 As early as the 1960s, Renzo et al 7 carried out a study on the contact characteristics of tooth pairs and proposed the problem of uneven distribution of the load of gear couplings in the case of equiaxial misalignment.…”

Three-arc gear couplings are machine elements which can meet the requirements of high load-carrying capacity. Effectively enhancing the load-carrying capacity of gear couplings has been an important research objective. Three-arc tooth design solution is proposed that effectively improves tooth performance, an analytical model of the three-arc tooth geometry parameters is given, and a functional relationship between key design parameters and load-carrying capacity and wear performance is established in this paper. The radius of the displacement circle and the radians of the three arc segments are used to design the three-arc tooth, the working domain coefficient and the radians of large arc are constructed and used as core variables. Through the Hertz theory and numerical simulation model, the contact theory of the hub tooth surface with modified drum coefficient is proposed, and the clearance, equivalent stress and surface contact stress of the tooth under the action of misalignment angle are studied, and then the evaluation model of the load-carrying capacity and wear performance of the three-arc hub tooth is established. Compared with the single-arc tooth, the three-arc tooth can improve the load-carrying capacity under the premise of ensuring the strength, misalignment angle and size, and at the same time, the reasonable design of the three-arc tooth can improve the wear performance.
