IKO non-standard bearing way to smooth the performance impact of profiling

When testing chrome steel and stainless steel as a bearing material advantages, found that they are not only have antirust function. Chrome steel is the most common non-standard bearing materials. It is more hard than stainless steel, so use life for its corrosion-proof. But at a higher temperature, its performance is not how to sample. Under the high temperature of 120 c, it will attack big deformation, load decrease. For the high temperature of 150 c it will also be able to endure, but for 150 c or higher temperature will reduce IKO bearing's life. Heat treatment can make the bearing to accept for the high temperature of 170 c. Bearing the smooth purpose is to reduce the non-standard bearing internal friction and the friction losses, avoid burning stick, its smooth effect is as follows. ⑴。 Reduce friction and friction losses. In a IKO bearing ring, rolling body and insist on mutual contact of the local and avoid contact with metal, reduce friction and wear. ⑵。 Longer fatigue life. IKO bearing rolling fatigue life, in the rotation, the rolling contact surface smooth and good, is extended. On the contrary, low oil viscosity, smooth and oil film thickness is not good, is reduced. ⑶。 Discharge frictional heat and cooling cycle to oil to oil discharge by the heat of friction attack, or coming from external heat, cooling. Avoid overheating bearing, smooth oil itself. ⑷。 Other also has to avoid foreign body into the bearing internal, or avoid the effect of rust and corrosion. Rolling bearing smooth can smooth agent on the basis of using the ordinary varieties are divided into smooth smooth, grease and oil and solid smooth three categories. Including smooth oil has more than the other way to smooth wide temperature range, more suitable for the work under the condition of high speed and high load bearing; Smooth also has the equipment at the same time, because the oil remaining and smooth agent change bento, friction pair in the system such as gear can at the same time the advantages of smooth, so far, non-standard bearings use smooth oil is most common. Fat has a smooth seal simple installation, low maintenance cost as well as the advantages of low fat, smooth temperature operating in low speed, medium speed, IKO bearings in common use. Especially anti-wear additives in recent years, advances the smooth performance of fat, make fat smooth has been more common used. If apply oil smooth and smooth fat reach bearing the requested smooth conditions, or failing to meet specific working conditions, can use solid smooth agent, or try to progress smooth performance of the bearing itself. The cause of the bearing noise compared complex, one is the bearing inner and outer appearance and wear. Due to the wear and tear, destroyed IKO bearing shell and cooperate relationship, rolling bearing and shaft, incur axis deviation from the correct position, when axis at high speed movement produces sound. When tired of non-standard bearing, metal peeling off its appearance, also can produce sound make bearing radial clearance increases.
