Application Characteristic Analysis of Spherical Roller Bearing in Industrial Gearbox

Blog Article

The spherical roller bearings are widely applied in industrial gearbox,therefore the research of the running character of spherical roller bearings in gearbox is important for the designer.Comparing to the cylindrical roller bearing and Reloading tapered roller bearing with same envelop dimension,spherical roller bearing has higher basic dynamic load carrying capacity and compensation of angular misalignment,but the modified rating lifetime calculated by using Bearinx is smaller,the contact pressure of roller is higher.The simulation of the running characters of spherical roller bearing is carried out by using program Caba 3D,it could be found that Night Calm there are big difference of rotating speeds between both rows of cages,as well as both rows of rollers,while the load is changed,the cages and rollers would be subjected to additional shock loads because of the change of running character.
