The temperature of the FAG bearing, generally the temperature outside the bearing can be inferred. If the oil hole can be used to directly measure the temperature of the outer ring of the FAG imported bearing, it is more suitable.
Generally, the temperature of FAG bearings starts to rise slowly with the operation of the bearings and reaches a steady state after 1-2 hours. The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation parts are suitable, the bearing temperature will rise suddenly and abnormally high temperature will appear. At this time, the operation must be stopped and necessary precautions must be taken. ERIC BEARING FAG 6016-2RSR online , pls contact with us :
The thermal sensor can be used to monitor the working temperature of FAG bearings at any time, and to automatically alarm or stop when the temperature exceeds the specified value to prevent burning shaft accidents.
High temperatures often indicate that FAG bearings are already in abnormal conditions. High temperatures are also harmful to bearing lubricants. Sometimes overheating of bearings can be attributed to bearing lubricants. Long-term continuous rotation of FAG bearings at temperatures exceeding 125 ° C will reduce bearing life. The causes of high temperature FAG bearings include: insufficient lubrication or excessive lubrication, lubricants. It contains impurities, excessive load, bearing damage ring, insufficient clearance, high friction caused by oil seal, etc. ERIC BEARING FAG 29414-E1 online , pls contact with us :
Therefore, it is necessary to continuously monitor the temperature of FAG bearings. Whether FAG bearings measure the bearings themselves or other important parts. If the operating conditions remain unchanged, any temperature change may indicate that a failure has occurred.
Clean heat treatment
Waste water, waste gas, waste salt, dust, noise and electromagnetic radiation formed by heat treatment production will cause pollution to the environment. To solve the environmental pollution problem of heat treatment, the implementation of clean heat treatment (or green environmental heat treatment) is one of the development directions of heat treatment technology in developed countries. In order to reduce the emissions of SO2, CO, CO2, dust and coal slag, the use of coal as fuel has been basically eliminated, and the use of heavy oil has become less and less. The majority of light oil is used. Natural gas is still the most ideal fuel. The waste heat utilization of the burner has reached a very high level. The optimization of the burner structure and the strict control of the air-fuel ratio ensure that NOx and CO are reduced to a minimum under the premise of reasonable combustion; gas carburization and carbonitriding are used And vacuum heat treatment technology is used to replace salt bath treatment to reduce the pollution of waste water and CN-toxic substances to water sources; water-soluble synthetic quenching oil is used to replace part of the quenching oil, and biodegradable vegetable oil is used to replace part of the mineral oil to reduce oil pollution.
Precision heat treatment
Precision heat treatment has two meanings: on the one hand, it uses physical metallurgy knowledge and advanced computer simulation and testing technology to optimize process parameters according to the use requirements, materials, and structural dimensions of the parts, to achieve the required performance or maximize the use of materials On the other hand, it is to fully ensure the stability of the optimized process, achieve a small (or zero) product quality dispersion and zero heat treatment distortion.
Energy-saving heat treatment
Scientific production and energy management are the most potential factors for efficient use of energy. Establishing a professional heat treatment plant to ensure full production and give full play to equipment capabilities is the choice of scientific management. In terms of heat treatment energy structure, primary energy is preferred; full use of waste heat and waste heat; low energy consumption and short cycle technology is used to replace long cycle and high energy consumption technology.
Less oxidation-free heat treatment
By using protective atmosphere heating instead of oxidizing atmosphere heating to control atmosphere heating that accurately controls carbon potential and nitrogen potential, the performance of parts after heat treatment is improved, heat treatment defects such as decarburization and cracks are greatly reduced, and the amount of finishing after heat treatment is reduced , Improve the utilization rate of materials and machining efficiency. Vacuum heating gas quenching, vacuum or low-pressure carburizing, nitriding, nitrocarburizing and boronizing can significantly improve quality, reduce distortion, and increase life. The heat treatment quality control of FAG bearing parts is the most stringent in the entire machinery industry.
