Some internal characteristics of transmission gears

The transmission gear may not be familiar with everyone. I don't know where to know this product. In this case, how can we fully understand the characteristics of the product?

1. The transmission gear ratio is large; As long as the type of planetary transmission and gear matching scheme are properly selected, a few gears can obtain a larger transmission ratio. In the planetary mechanism which is not used as power transmission mainly for transmitting motion, its transmission ratio can reach thousands. In addition, because the three basic components of the gearbox gear drive can rotate, it can realize the synthesis and decomposition of motion, as well as complex motion such as stepless and stepless transmission.

2： The gearbox gear has small volume, light weight, compact structure, large transmission power and high bearing capacity; This feature is determined by the structure of planetary gear transmission and other internal factors.

1. The gearbox gear is a coaxial transmission device. Each central wheel forms coaxial transmission, input shaft and output shaft, which greatly reduces the size of the transmission device in the length direction.

2. Gearbox gears shall be reasonably meshed. Make full use of the high internal meshing bearing capacity and the space volume of the internal gear (or internal gear ring) to reduce the radial and axial dimensions, so as to make the structure compact and the bearing capacity high.

3. The transmission gear has the power split principle. Several identical planetary gears are evenly distributed around the central wheel and share the load, so that the load of each gear is smaller and the corresponding gear module is smaller. Under the average load, the shape and size of the planetary gear will also decrease with the increase of the planetary gear.
