Product Description

Product Description


The gearbox transforms the motor's high-speed rotation into powerful, slow-turning force for the screws. It keeps the screws perfectly in sync and handles the strong pushing forces inside the machine.


Primary Functions


The primary functions of a gearbox are speed and torque conversion and motion control. It reduces a high-speed, low-torque input from a motor into a lower-speed, higher-torque output suitable for the driven machinery. Additionally, it can change the direction of rotation and transmit power efficiently between components.

Key characteristics


Housing: A robust casing that encloses and protects internal parts.

Gears: The primary components (spur, helical, planetary, etc.) that mesh to transfer power and change speed/torque ratios.

Shafts: Input, output, and intermediate shafts that support and rotate the gears.

Bearings: Support the shafts, allowing them to rotate smoothly under load.

Seals: Prevent lubricant leakage and contamination ingress.
