Gearboxes are mechanical systems that can operate smoothly for many years when used correctly. However, this durability is ensured through regular maintenance. If routine procedures such as lubrication, cleaning, connection checks, and performance monitoring are neglected, gear wear, bearing failures, and efficiency losses become inevitable.

Oil Level and Quality Check Frequency: 500 hours after initial operation, then every 2500–3000 hours. Procedure: Check the oil level and add oil recommended by the manufacturer if needed. Contaminated oil or oil with reduced viscosity must be replaced. |
Leakage Inspection The housing, shaft seals, and connection points should be checked for oil leakage. If leakage is detected, the seal or gasket should be replaced. |
Vibration and Noise Monitoring Abnormal vibration or noise may indicate gear damage or bearing problems. Vibration analysis should be carried out if necessary. |
|
Inspection of Fastening Elements Mounting bolts, cover screws, and shaft connections should be checked against loosening. If necessary, tightening should be done with a torque wrench. |
Monitoring Environmental Conditions Dust, humidity, extreme temperature, or chemical vapors shorten gearbox life. The operating area should be kept as clean as possible and at a suitable temperature. |
Periodic General Maintenance According to the manufacturer’s recommendation, gears, shafts, and bearings should be visually and dimensionally inspected during annual maintenance. Worn parts should be replaced if necessary. |
