Gearbox Installation
1. Hammering is Strictly Prohibited
When installing connecting components such as couplings, pulleys, or sprockets onto the gearbox output shaft, direct hammering must not be used. The output shaft structure cannot withstand axial impact. Instead, utilize the threaded hole at the shaft end: screw in a bolt to press-fit the connecting component.
2. Always Install the Vent Plug (Air Vent Screw)
Before operation, replace the plug at the highest point with the provided air vent screw. This ensures that gas generated inside the gearbox during operation can escape. Failure to do so may cause prolonged internal pressure buildup, damaging the oil seal and leading to oil leakage.
3. Timely Lubricant Replacement, Especially the First Change
Particular attention must be paid to the initial oil change. The lubricant should be replaced after the first 300–400 hours of operation. Subsequently, change the oil every 1500–2000 hours. Furthermore, in harsh working conditions—such as high temperatures or dusty environments—the lubricant should be inspected every two weeks. Replace it immediately if contamination is found. Maintaining clean oil extends the gearbox's service life and improves economic efficiency.
Gearbox Use and Maintenance Guidelines
1. Initial Operation Period
During the first two weeks of operation, the lubricant should be replaced periodically. In severe environments, regularly check for oil degradation or contamination. For gearboxes that have been idle for an extended period, replace the oil before putting them back into service. Always use the same type, specification, brand, and appropriate viscosity of lubricant as the original.
2. Lubricant Replacement Procedure
When changing the oil, ensure the gearbox has cooled down to ambient temperature to avoid burn hazards. If the gearbox is completely cold and oil drainage is difficult, let it idle until it reaches a normal operating temperature before proceeding.
3. Handling Abnormal Conditions
If abnormalities such as excessive temperature or unusual noises occur during operation, stop the gearbox immediately. Investigate and resolve the issue before resuming normal operation.
4. Operator Responsibilities
Personnel must strictly follow operating procedures and maintenance schedules to ensure the equipment remains in optimal working condition. Detailed records should be kept during inspections and maintenance for future reference.
Important Note on Lubrication
A gearbox achieves speed reduction through the meshing of gears on the input shaft. Due to its working principle, the gears experience wear over prolonged use. Adequate lubrication between gears significantly reduces this wear. Therefore, the service life of the gearbox is closely tied to the quality and condition of its lubricant.
