Features

Working Principle of the K-Series Gear Reducer

First Stage: Uses spiral bevel gears to change the direction of power transmission (typically by 90°).

Second Stage: Uses helical gears to achieve speed reduction and torque amplification.

Consequently, it offers a combination of the following features:

Change in output direction

High load-bearing capacity

Smooth, low-noise operation

High efficiency

Helical Bevel Gearbox Structure

Bevel Gear

Function:

Alters the direction of power transmission.

Typically involves a horizontal motor input → vertical output.

Features:

The axes of the gears intersect.

Generally conical in shape.

Spiral bevel gears are commonly used due to their lower noise levels.

Helical Gear Section

Function:

Achieves speed reduction

Increases output torque

Features:

Continuous tooth surface contact

Smooth operation

High load-carrying capacity

Lower noise level compared to spur gears
