Question regarding axial force in helical gear transmission
Thread Content
Compared to straight-tooth transmission, helical tooth transmission in reducers is also subject to an axial force; when teeth come into contact with each other, isn’t there only a radial force at play? Why does a helical gear transmission experience an additional axial force compared to a spur gear transmission?
Isn’t there a tangential force at the point of contact between the driving wheel and the driven wheel? When this tangential force acts on the helical teeth, it is divided into an axial force and a radial force.
Force is decomposed into an axial force and a radial force
The orthogonal decomposition of forces? I’ve already given that middle school knowledge back to the teacher.
The force acting on helical gears is directed along the meshing surface between the two gears. This force can be broken down into two components along the radial and axial directions of the gears, namely radial force and axial force. Helical gear transmission is continuous and smooth, but an axial force is present; generally, to eliminate this axial force, the helical gears are arranged back to back in pairs!
