Gear is a kind of common occlusion device. Many parts have gears. Without gears, many equipment can not work smoothly. There are some parameters need to be referred to in the use of gears, which have an impact on our gear work. Gear coefficient is a very important index. Now let's understand the meaning of each coefficient. I hope our introduction will help you. As a reliable gear manufacturer, our gear processing experience is relatively rich, and provide a variety of gears, let's have a look!

Service factor Ka: it is a factor considering the influence of additional dynamic load caused by external factors during gear engagement. The dynamic load depends on the characteristics, mass ratio, coupling type and operation state of prime mover and driven machine.

Dynamic load coefficient kV: it refers to the coefficient considering the dynamic load influence generated by the gear self meshing transmission. It is related to manufacturing and assembly error, peripheral speed, etc.

Load distribution coefficient K α between teeth: it is a coefficient considering the influence of uneven load distribution between teeth. It is related to pitch error and elastic deformation.Load distribution coefficient K β in tooth direction: it is a coefficient considering the influence of uneven load distribution along the contact line on the tooth surface. It is related to the position of the gear relative to the bearing, the deformation of the shaft, bearing and support, as well as the manufacturing and assembly errors.
