INA deformed bearing stainless steel and overhaul response program '

Kunshan Bearing: INA stainless steel Backing bearings or components due to force change in size or shape occurring phenomenon known as deformation. Machinery and equipment production site because harsh working conditions, often work overload operation, a number of bearing deformation is very common. They make other related parts deformation accelerated wear, and even rupture, may also lead to system damage or the entire series bearing equipment damage, accidents caused by equipment, so deformed harm is very serious.
INA stainless steel bearings in effect when the stress is less than the material yield strength of the deformation is called elastic deformation. Plastic deformation, also known as permanent deformation, is the bearing parts in the external force (load) after the removal of that part of the deformation can not be restored. Excessive mechanical deformation is important type of equipment failure.
1. The use of reasonable cooling method:
After quenching cooling process of metal on the deformation impact is very important Deformation. Heat oil quenching oil quenching deformation than the cold, the general control of 100 ± 20 ℃. The deformation of the oil cooling capacity is crucial. Quenching of the mixing method and speed of impact deformation. Metal heat faster cooling rate, the more uniform cooling, the greater the stress, the mold becomes greater INA shaped stainless steel bearings.
(2) using the appropriate medium:
In the same hardness assurance requirements under the premise, as far as possible oily medium, experiments and proved again no difference in other conditions under the premise of oily medium slow cooling, while the aqueous medium, the cooling rate is relatively faster.
3 part structure to be reasonable:
Metal during cooling after the heat treatment, the thin part is always cold fast, slow cold thick portion.
INA stainless steel bearing vibration measuring reflected view, bearing vibration of the bearing damage is very serious, so, after the adoption of extraordinary bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration, measured through the frequency a very specific circumstances. Since the measured values ??due to the conditions of use of the bearing location or sensor install the difference, which is necessary in advance to each of the machine compared with the measured values ??after the affirmative judgment scale.
