“…In this model, tooth chain contact force is used to simulate meshing transmission, and the meshing force is solved according to user-defined input gear parameters and used for meshing position [ 14 ]. With the change of tool normal tooth pitch and normal tooth Angle, the intersection of tool normal tooth pitch line and sprocket tooth groove symmetry line will change correspondingly, so the tool meshing position on the sprocket should be adjusted accordingly.…”

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.

“…The parallel misalignment fault of a flexible coupling magnifies the displacement response at 2× amplitude, whereas the angular misalignment response is captured at 2× and 4× amplitudes [2]. Parallel and angular misalignments can both induce second-harmonic generation, but the influence of angular misalignment is more significant than that of parallel misalignment [3]. Cardan shaft misalignment causes an unbalanced force, which is the main load of bolt fatigue fracture of a high-speed train motor [4].…”

In order to improve the thrust-weight ratio, modern aeroengines generally adopt a coaxial dual-rotor system. Factors such as manufacturing errors, assembly errors, bearing wear, and structural deformation can cause misalignment failures in a dual-rotor system. Supporting misalignment is one of the common types of misalignments in a dual-rotor system. To analyze the vibration characteristics of misalignment faults, in this study, we aim to build a finite element model of a dual-rotor system with supporting misalignment. The bearing loads caused by supporting misalignment are calculated using the three-bending moment equation method. Bearing loads are introduced into the dynamic model of the dual-rotor system. The influence of supporting misalignment at different bearings on the dynamic characteristics of the rotor system is investigated based on the supporting misalignment model. Studies have shown that supporting misalignment at different bearings has similar effects on the dynamic characteristics of the dual-rotor system. The proposed supporting misalignment model is more adaptable than the coupling misalignment model. It indicates that the damping of a rolling bearing should be considered in the dynamic analysis of a dual-rotor system although the value of the damping is not large. An experimental analysis is carried out. The simulation results are in good agreement with the experimental results.

“…Moreover, the number of the hub teeth is the same as that of the sleeve teeth. Because of the advantages of compact structure, high loading capacity and wide speed range, crown gear couplings are widely used in high speed railway (Shinoda and Li, 2020), large ships (Fan et al, 2020), precision rolling machinery (Peng et al, 2018) and other equipment serving in complex working condition.…”

Crown gear couplings are commonly applied to transfer rotary motion and torsion from one rotating component to another under a certain misalignment angle. While computational models for contact analysis have recently been proposed, there is no validated contact analysis model of crown gear coupling with angular misalignment due to lack of experimental data. Accordingly, this study proposes to establish an extensive experimental database on contact characteristics of the conventional and novel crown gear couplings with different misalignment angles. A dedicated test rig, which can adjust misalignment angle, is designed and set up. A test matrix covering various misalignment angle conditions is executed in order to form a meshing contact database for crown gear coupling. The experimental data illustrates the variety of contact positions on the hub tooth surface caused by rotational position and misalignment angle. Simulation results obtained by loaded tooth contact analysis are compared to the experimental results for the conventional and novel crown gear couplings with different misalignment angles. The results show that the simulation model used to calculate contact analysis is effective, and the meshing performance of the innovative hub tooth profile is better than that of the conventional one.
