What is the primary transmission and secondary transmission of gears?

1. The first-stage transmission of gears refers to the fact that the power transmission relies on a pair of meshing gears.

2. Secondary transmission means that the power transmission is carried out by relying on two pairs of meshing gears.

Gear transmission characteristics Gear transmission is a mechanical transmission that transmits power and motion by using the teeth of two gears to mesh with each other. According to the relative position of the gear axis, it is divided into parallel axis cylindrical gear transmission, intersecting axis bevel gear transmission and staggered axis helical gear transmission. It has the characteristics of compact structure, high efficiency and long service life.
