How Frequent Starts and Stops Affect Gearbox Life?

Key Takeaway: Frequent acceleration and deceleration create repeated peak loads, And increase gear loading, Thermal and mechanical loads on bearings and lubrication systems.

Increased Mechanical Shock

Each Start, Braking and reversing generate inertial torque, The higher the frequency, The more load cycles gears and bearings experience.

Temperature Rise Can Also Increase

Frequent acceleration and deceleration increase losses, Even When the Average Load Is Low, Accumulated heat can raise the temperature.

How to Improve?

Increase Acceleration/Deceleration Time, Increase the Gearbox Safety Margin, Optimize Inertia Matching, Check for Excessive Load Inertia.

How to Apply This Information to Selection?

Do not make a final selection from a single parameter. Review the motor model, Load, Target Output Speed, Torque, Inertia, Check acceleration/deceleration time and mounting interfaces together, Then select the series and model.

FAQ

Is Longer Acceleration Time Always Better?

No. Balance Machine Cycle Time & Mechanical Shock.
