®Technical Guides
Practical engineering guides covering gearbox output torque calculation, ratio and speed selection, service factor interpretation, mounting position conventions (M1–M6), IEC motor interface compatibility, lubrication, overheating diagnostics, noise and vibration troubleshooting, shaft-end configuration and replacement workflow.
How to Calculate Gearbox Output Torque
Output torque is one of the most important values in gearbox selection. A useful engineering estimate is T = 9550 × P × η / n₂.
Read guide →How to Calculate Gear Ratio and Output Speed
For a simple reduction gearbox, output speed is approximately input speed divided by the transmission ratio.
Read guide →Industrial Gearbox Lubrication Guide
Correct lubricant type, quantity and maintenance practice are essential to gear and bearing life.
Read guide →Gearbox Mounting Positions M1–M6 Explained
Mounting position determines gearbox orientation and can change lubricant quantity and internal oil distribution.
Read guide →Gearbox Noise and Vibration Troubleshooting
Noise and vibration are symptoms rather than diagnoses. Track when the symptom occurs, load dependence, frequency, temperature and recent changes.
Read guide →Gearbox Overheating: Common Causes and Checks
Abnormal gearbox temperature can be caused by overload, incorrect lubrication, misalignment, excessive input speed, restricted cooling, bearing problems or internal damage.
Read guide →What Is Gearbox Service Factor?
Service factor is a selection margin used to account for duty severity beyond nominal power and torque.
Read guide →IEC Motor Frame and Gearbox Interface Guide
Motor power does not uniquely determine the gearbox input interface. Motor frame, mounting form, flange dimensions and adapter geometry must be checked together.
Read guide →Industrial Gearbox Replacement Checklist
A gearbox is not a direct replacement simply because the ratio or size code is similar.
Read guide →Solid Shaft vs Hollow Shaft Gearbox
Solid and hollow output shafts solve different machine-interface problems.
