Smooth fat viscosity of IKO bearing analysis of the influence of the rolling mill

Physical activity within a measure of the friction force is called viscosity, in order to avoid the motion parts between contact surface wear, rolling mill bearings must have enough smooth oil viscosity, viscosity values by the rise of temperature. Smooth oil viscosity is evaluated IKO bearing the quality of an important function of the physical and chemical indicators, about producing, transportation and use has important significance. Smooth oil viscosity is bearing the main technical indicators, but smooth IKO bearing oil viscosity shall not be higher than thought affects hair start level, the vast majority of smooth bearing is based on its viscosity grade of oil, the viscosity is mainly based on the selected oil of various equipment. Viscosity measurement method of divided into two categories: absolute viscosity and relative viscosity. Absolute viscosity can be divided into dynamic viscosity and kinematic viscosity of two; Relative viscosity kind's viscosity, saybolt viscosity and viscosity redwood said several ways. Use stick through the large smooth rolling mill bearing oil will increase the wear and tear of parts, in practical application, the appropriate choice of smooth oil viscosity, work to ensure the normal order of the mechanical equipment, firmly. Usually, the application of low speed high load place, choose larger oil viscosity, to ensure adequate oil film thickness and normal smooth; High-speed low load applications, choose the smaller oil viscosity, mechanical equipment to ensure the normal starting and running torque, smooth hair idea oil stick through the large, slow, slow high, oil pressure is high, but smooth oil amount through a matter, can't timely supplement to the friction surface, under the precondition of continuous running of friction is minimal. Due to the rolling mill bearing smooth tanker back slowly, after bearing the number of smooth oil filter is less, difficult to chip will wear off in time at the end of the metal, carbon particles, dust from the friction surface cleaning. Operation, because of the large smooth oil viscosity in part increases the friction between the friction surface, for restraint increase friction, more fuel, but also reduces the idea of power output. IKO bearing smooth oil viscosity, oil cycle speed is slow, the cooling and heat dissipation effect is bad, make the hair idea easily overheat. Small so that under the different operating temperature, the temperature can form the oil film between the movement of parts. So, don't use sticky thought crossed the big hair smooth oil, can't even think that the greater the viscosity, the better. On the premise of guarantee the smooth, on the basis of the range of temperature in the use of, as far as possible choose smooth oil of low viscosity. But for serious wear has compare, the gap has been compared big hair, we can choose proper viscosity larger smooth oil.
