IKO bearings running smooth points in the process of stainless steel

If two incompatible oil mixing, never mix incompatible grease. Usually consistency will soften, finally formation damage due to oil easy to loss, if you don't know you IKO bearings using the original smooth fat, is to the original oil up the first, and then add a grease smooth stop. The use of our stainless steel process will often encounter this or that kind of situation, and how these conditions, how to handle when constitute, is the technical personnel of each big enterprise unceasingly the most headache problem, the following points in the use of the machinery is IKO bearing attacks when overheating phenomenon of the causes and treatment of give you detailed introduce you: grinding the instantaneous high temperature can make certain depth (appearance 10 ~ 100海里) Be heated to a temperature higher than the workpiece temperature tempering heat. In did not reach the austenitizing temperature conditions, with the progress of heated temperature, its appearance will produce one by one and heating temperature corresponding to the organization transformation, or high temperature tempering tempering hardness also fall subsequently. The higher the heating temperature and hardness of the land is also increasingly fierce. In the grinding, grinding wheel and workpiece contact zone, can cost a lot of, have a lot of grinding heat, form a grinding zone of instantaneous high temperature. On the basis of the theory of linear motion heat source heat transfer formula derivation, calculation or by the method of infrared ray and measured experiment under the condition of instantaneous temperature thermocouple method, hair is 0. 1 to 0. The grinding area within 001 ms instantaneous temperature up to 1000 ~ 1500 ℃. The instantaneous high temperature, enough to make certain depth work looks outside surface to produce high temperature oxidation, amorphous group, high temperature tempering, secondary hardening, cracking and burns, etc. Instantaneous high temperature under the action of steel appearance and oxygen in the air, rises into extremely thin ( 20～30nm） The iron oxide thin layer. Keep in mind oxide layer thickness and the appearance of grinding metamorphosis layer is the total thickness test results in corresponding relation. This clarify the thickness of oxide layer, is directly related to the grinding process is an important symbol of grinding quality. Use within IKO bearing grease has rust protection. Antirust performance is mainly is to look at the fat soluble, different degree of thin and smooth, composed of different materials with different levels of capacity and antirust performance, ordinary, thin of big and fat soluble oil water proofing property is better, so that oil even in a stainless steel bearing cavity filled with water, can also be in the steel surface layer can withstand oil film. Bike because of the low speed, the choice of grease can be relatively use slightly thin degree is high, but the water proofing property is extremely strong, because the bike in washing the car, rainy days, cross-country, are often dealing with water, this makes the water proofing property is very important, even slightly thin oil, also won't affect under low rotate smoothly, and constitutes the oxidative damage once appearance, that the whole stripping process and the ageing process will be quick.
