Contact stress of helical gear in automobile transmission

Due to the complex contact problem of helical gear, further research is needed in the following aspects:

① Fully parametric modeling of involute helical gear, including fully parametric modeling of helical gear shaft model.

② The problem of thermal fluid coupling of helical gear and helical gear contact field is a problem related to the thermal fluid coupling of helical gear. The research only involves the contact stress field of helical gear, without considering the influence of temperature, lubrication and other factors on its contact stress.

③ The actual transmission system includes the box, helical gear, helical gear shaft and bearing and the connection form of each component. In the research work, only the influence of the stiffness deformation of helical gear shaft on its contact stress is involved.
