Some elements of influencing motor bearing minimum load

Affect the motor bearing some elements of the following factors endangering the minimum load bearing of the size of the smallest load bearing speed than motor bearing job transfer ratio is higher, the minimum load. So in the same motor bearing selection, for the use of high-speed rotation, must check the minimum load conditions. Bearing the diameter of the bearing diameter is larger, the higher the minimum necessary to load. In other words, the greater the bearing, the higher the minimum necessary to produce rolling load. Bearing the total width of comprehensive considering the bearing diameter and the harm of overall width, not too hard to find, the load bearing ability to work, the higher, the minimum load is also relatively large. Therefore, on the whole, cylindrical roller bearing is bearing the minimum load over deep groove ball bearings must be a minimum load. Motor bearing application RunHua temperature in a work bearing lubricant base oil viscosity on the basis of bearing temperature in the oil viscosity, the greater the minimum necessary to produce rolling load will lead to greater. Not enough conditions will continue to produce minimum load in another situation, when the temperature is too low, under the condition of bearing internal lubricating oil viscosity is too large, will cause bearing rolling necessary minimum load increases, when the motor running, then there will be a minimum load bearing is not enough. Deal with this kind of situation, must be appropriate to reduce the viscosity of lubricating grease. Or in the case of motor temperature is too low ( Especially under the condition of hot starting) According to some auxiliary heating way, rise the temperature of the motor bearing interior lubricating grease, reduce its viscosity, make to rolling motor bearing is easy to start. The above is the content of the author to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website.
