The emergence of INA stainless steel bearing deformation overhaul plan

INA stainless steel bearing or component due to the force change size or shape is called deformation. The scene of the production machinery and equipment because of the bad working conditions, are often overloaded operations, some bearing deformation is very common. Their deformation will lead to accelerated wear and other related parts and even rupture, and may lead to system series bearing damage or damage to the device, caused the accident, so the harm of deformation is quite serious. INA bearings in the applied stress is less than stainless steel material yield strength when the deformation is called elastic deformation. Plastic deformation, also known as permanent deformation, is refers to the bearing parts in the external force ( Load) After removing, cannot recover part of the deformation. Excessive deformation is an important type of machinery and equipment failure. 1. Reasonable use of cooling method: metal cooling process after quenching effect on the deformation is also important a reason. Hot oil quenching oil quenching than cold deformation is small, general control in the 100-20 ℃. Oil cooling ability of deformation is also very important. The mixing way and speed of the quenching influence the deformation. The faster the cooling rate of metal heat treatment, the uneven cooling, the stress, the greater the mould INA stainless steel bearing of shape. 2. Use appropriate medium: on the premise of guarantee the same hardness requirements, as far as possible the oily medium, experiment and practice has proved that to other conditions under the premise of no difference, the slower cooling rate of oily medium, and the cooling speed of water medium is relatively fast. 3. Parts structure to be reasonable: metal during cooling after heat treatment, is always the thin part soon cold, the thick part of the cold slowly. INA reflected in stainless steel bearing vibration measuring, bearing vibration of bearing damage is very serious, in that, by adoption of extraordinary bearing vibration measuring device ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points to measure very specific circumstances. Due to the measured values due to the use of the bearing condition or sensors installed position and differences, therefore necessary prior to each machine after analysis compared with the measured values must determine scale.
