Small crane transmission failure Prevention
The bearings and gear pairs of the power shift transmission are vulnerable parts, so the transmission should be inspected and maintained regularly. The maintenance interval of a typical foreign transmission is one. According to my country's national conditions, it is recommended that the clutch wear should be checked every other time, and abnormal signals should be caught at any time. Since powershift transmissions are unlikely to fail quickly, they can usually continue to be used after the first signs of wear on the friction pads -. If frequent inspections and maintenance are performed during this period, and friction plates, seals and individual bearings are replaced in time, the small crane can avoid damage to undamaged parts (such as steel sheets, gears, shafts, hydraulic cylinders and most bearings, etc.).
The following abnormal conditions often occur before the crane clutch fails:
Although the machine can still work, the oil in the transmission has already deteriorated, the viscosity has dropped and contains metal impurities, so it should be changed at the recommended oil change interval Analyze transmission oil samples more frequently before each period. Because clutch wear is a sign of transmission failure, if metal impurities enter the gear pair or jam the gears so that they cannot be aligned, other components in the transmission will be crushed if the engine is not shut down.
Reduced shifting performance is a sign of clutch damage. When the clutch begins to slip, the machine will rush forward even if it is accelerated smoothly. At this time, the machine should be shut down for maintenance.
The clutch control oil level drops, and when the machine must accelerate to engage the clutch, it indicates that the clutch has been excessively worn or has a seal failure. Therefore, clutch wear can be determined by measuring the oil pressure of the transmission and observing whether the oil temperature rises.
At the same time, the oil quality should also be analyzed. If iron or chromium particles appear in the oil, it indicates that the gear pair has begun to wear.
