A Review on Friction Torque of Tapered Roller Bearings

Modern machinery runs on high power density and speed to satisfy the needs of day-to-day services. Tapered Roller Bearings (TRBs) are often selected as it capable of accommodating high axial or radial load or combining axial and radial load simultaneously at high speed. On other hand it results in massive friction losses which causes energy loss and heat generation. An accurate estimation of friction torque measurements becomes essential to estimate bearing power loss accurately. This work presents an overview of analytical and experimental modeling and analysis methods for predicting friction torque with varying operating conditions in TRBs. A literature summary is presented along with future scope of work.
