Overview of TPB series planetary reducer, or called planetary gearbox:

1. The box body is made of ductile iron, which greatly improves the rigidity and impact resistance of the box body.

2. Adopt involute planetary gear transmission, rationally use internal and external gears and power distribution. Therefore, it has the characteristics of light weight, small volume and wide transmission ratio range.

3. Input mode: concentric shaft input, helical gear input, bevel gear-helical gear input, bevel gear input.

4. Output mode: internal spline type, hollow shaft shrink disk type, external spline type, solid flat key.

5. Installation form: horizontal installation, vertical installation, torsion arm installation.


Application of TPB series planetary reducer:

TPB series planetary gear reducer is light in weight, small in volume, wide in transmission ratio range, high in efficiency, stable in operation, and low in noise adaptability. Reducers are widely used in metallurgy, mining, lifting and transportation, electric power, energy, building materials, light industry and transportation and other industrial fields.
