What is a gear?
Gears are mechanical parts with teeth that mesh with each other. It is widely used in mechanical transmission and the entire machinery field.
Gear transmission can complete functions such as deceleration, speed increase, and direction change.
What are the characteristics of grinding spiral bevel gears?
The spiral bevel gear is conical, like an umbrella, with high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high load-bearing capacity, stable and smooth transmission, reliable operation, compact structure, energy and material saving, space saving, and wear resistance. Long life and low noise.
