Tooth surface meshing of cycloid hypoid gear

Taking the “Austrian” cycloid hypoid gear used in the axle as the research object, the geometric parameters and cutting parameters are calculated, and the full tooth surface model considering the blade arc and tip arc is established. The geometric contact analysis is carried out by using the improved TCA...

Active design technology of gear tooth surface

The active design technology of gear tooth surface designs the shape of gear tooth surface according to the functional requirements of gear transmission. First, the meshing performance of mating gear tooth surface is preset, that is, the transmission error curve and the best contact mark, and then the gear...

Gear tooth surface error detection and correction technology

Due to the inevitable machining error and heat treatment deformation, the actually processed gear tooth surface often deviates from the theoretical design tooth surface or the standard gear tooth surface, and due to the general backwardness of domestic heat treatment technology, this deviation will be larger, sometimes up to...

Helical gear transmission considering tooth surface friction

The dynamic characteristics of helical gear transmission considering tooth surface friction are studied and further studied and discussed: (1) Due to the large investment scale of heavy helical gear, the construction of helical gear transmission test-bed in the transmission basic research project is still in progress, and the experimental...

Research status of spur gear tooth surface friction

In the early research, because the dynamic impact theoretical analysis and experimental analysis of tooth friction are also limited, the tooth friction is often ignored. However, the research shows that the spur gear vibration and noise are still very large even if the transmission error of spur gear is...

Gear tooth profile modification

In recent years, many scholars have done a lot of research on gear modification, and there are many modification methods of gear tooth direction. Referring to a large number of relevant materials, there are three common methods with good modification effect: tooth end modification, drum modification and spiral angle...
