How to prevent gear damage of SF57-YB1.5KW-55-M6 reducer with hard tooth surface

To prevent damage to the gears of the SF57-YB1.5KW-55-M6 reducer with hard tooth surfaces, the following measures can be taken:

Reasonable selection and installation

Correct selection: Based on actual working load, speed, transmission ratio and other parameters, choose a suitable specification of reducer to ensure that its rated load and power can meet the working requirements and avoid long-term overload operation.

Accurate installation: High precision measuring instruments should be used during installation to ensure that the input and output shafts of the reducer maintain good coaxiality and perpendicularity with the shafts of other equipment. The error should be controlled within the specified range, such as axis parallelism ≤ 0.02mm/m and radial runout>0.05mm. At the same time, the foundation of the reducer should be firm and horizontal, and the anchor bolts should be tightened to prevent vibration and displacement during operation.

Optimize lubrication management

Choose the appropriate lubricating oil: Based on the working conditions of the gearbox, such as operating temperature, load size, etc., choose lubricating oil with appropriate viscosity and performance. Generally speaking, high viscosity extreme pressure gear oil such as ISO VG 320 can be used for hard tooth surface reducers.

Regularly replace lubricating oil: Replace lubricating oil regularly according to the manufacturer's recommendations or equipment operating conditions. At the same time, when replacing lubricating oil, it is necessary to thoroughly clean the oil tank and oil circuit to prevent impurities from remaining in the old oil.

Monitoring oil quality: Regularly test lubricating oil, such as viscosity, moisture, acid value, etc. every 500 hours. When the acid value is greater than 1.0mgKOH/g, the oil needs to be changed. Use an iron spectrometer to analyze the composition of abrasive particles. Be alert when the iron content is greater than 50ppm, and promptly detect changes in oil quality and potential wear problems.

Control operating conditions

Avoid overload and impact load: Strictly operate according to the rated load of the reducer to avoid sudden overload or impact load. When starting and stopping the equipment, it should be smooth to prevent excessive stress on the gears due to material jamming and other reasons.

Control the working environment temperature: Maintain a suitable temperature for the working environment of the gearbox and avoid prolonged operation in high or low temperature environments. If the working environment temperature is too high, a cooling device such as a plate heat exchanger can be installed to control the oil temperature to ≤ 70 ℃.

Keep the environment clean: Regularly clean the dust, oil stains, and other debris around the gearbox to prevent dust and impurities from entering the interior of the gearbox, contaminating the lubricating oil, and wearing the gear surface.

Strengthen daily maintenance and monitoring

Regular inspection: Conduct a comprehensive inspection of the gearbox regularly, including the meshing condition of the gears, the wear condition of the tooth surface, the clearance and temperature of the bearings, etc. Measure the gear tooth thickness once a year, repair if the wear exceeds 10%, and replace if the bearing clearance exceeds 150% of the initial value.
