The gearbox must deliver enough torque to move the load without exceeding its rated capacity.
Output Speed
Determine the desired output RPM based on the equipment being driven.
Gear Ratio
The gear ratio establishes the relationship between input speed and output speed while influencing torque multiplication.
Service Factor
Applications involving shock loads, frequent starts and stops, or continuous-duty operation often require a higher service factor to provide additional reliability.
Operating Environment
Environmental conditions influence gearbox selection.
Consider factors such as:
Dust
Moisture
Washdown requirements
Corrosive chemicals
Ambient temperature
Outdoor exposure
Mounting Configuration
Choose a gearbox that matches the equipment's installation requirements, including shaft orientation, mounting style, and available space.
