Working principle: Bevel gear transmission refers to the meshing of two bevel gears to transmit motion and power between intersecting axes. The meshing transmits motion and power through tooth surface contact, and the tooth surface contact line changes continuously during the meshing process. The transmission ratio calculation formula is i=frac{n_1}{n_2}=frac{z_2}{z_1}, where n_1 and n_2 are the speeds of the driving gear and the driven gear respectively, and z_1 and z_2 are the number of teeth of the driving gear and the driven gear respectively.
- Structure: It mainly consists of four parts: cone, gear shaft, gear hub and gear pair. The cone is the main component, which looks like a cone and has high precision and surface finish. The gear shaft acts as a transmission shaft to transmit the rotational motion to the gear hub. The gear hub is a circular part used to mesh with the gear pair to achieve rotational transmission.
