1. Closed power flow herringbone gear test bench Compared with the traditional open power flow test-bed, the closed power flow test-bed used in this experiment is more energy-saving. Closed power flow means that the route of energy transmission forms a closed loop in the entire test bench. The inverter...
According to the measured symmetry deviation, it can be known that in herringbone gear transmission system, the relative left rotation deviation of the driving wheel is 0.025mm, and the relative left rotation deviation of the driven wheel is 0.048mm. It is further obtained that the deviation of the center...
The structure and material properties of two pairs of helical gears in herringbone gear are the same, but due to the influence of symmetry deviation on gear mesh, the meshing stiffness of the left and right groups of helical gear pairs is different. The gear hub and shaft are...
As one of the common mechanical transmission modes, gear transmission is developing towards high speed, heavy load and high precision with the rapid development of science and technology, which also puts forward higher requirements for its dynamic performance. Herringbone gear not only has the advantages of stable transmission and...
According to the finite element simulation results of and axial displacement, the assembly offsets of 0.05 mm, 0.1 mm, 0.15 mm and 0.18 mm are taken for the gear pair respectively, and the compensation for the alignment error of herringbone gear is analyzed. The cloud diagram of tooth surface...
As the force along the axis of gear meshing, the axial force determines the axial vibration of gear, and indirectly reflects the stress in other directions. Similarly, the analysis of axial force is also divided into three stages. The axial force change curve of herringbone gear with different centering...
When the herringbone gear pair with alignment error is meshed, the eccentric load on the tooth surface will have a great impact on the axial impact vibration and dynamic characteristics of the system. In order to facilitate the qualitative analysis of relevant results, the transmission is divided into three...

A contact model considering the coupling effect...
Based on the accuracy standard, combined with the structural constraints of large energy machinery and equipment and the requirements of normal meshing transmission of herringbone gear, the machining accuracy of herringbone gear is generally controlled within level 6. However, since the symmetry of the left and right tooth surfaces...
In order to verify the accuracy of the load contact analysis model of herringbone gear with centering error, a three-dimensional model of herringbone gear pair with centering error is established. According to the requirements of machining herringbone gear, the centering error is required to be controlled within grade 6...
