# Gearbox Input Shaft

## Input Shaft

The gearbox input shaft connects to the motor and transmits torque to the first stage. It operates at high speeds and bears significant loads from the motor. Input shaft bearings must ensure precise alignment and minimal losses.

## Operating Conditions

- High rotational speed
- Radial and axial loads from the motor
- Vibration from uneven torque
- Need for precise alignment

## Solutions

Angular contact ball bearings and cylindrical roller bearings are used for high-speed operations. Preloaded bearings are employed to increase rigidity. Oil lubrication is recommended for high-speed shafts.
