In order to measure the friction torque of bearings at different temperatures,a new type of bearing friction torque measurement equipment was designed based on the measurement principle of the transfer method.The process hole in the lower layer of the incubator in the equipment was sealed with a sealed structure,and in view of the impact problem generated by the tested bearing and the measuring spindle during the docking,a new type of rat-like detachable clamp was designed to achieve a smooth transition.LabVIEW was used to write related motion control,data acquisition,and control interface programs.After the program was calculated and processed,the bearing friction torque value,change curve and other data were obtained.Finally,this equipment was used to measure the friction torque of SKF7207 deep groove ball bearings.The results show that the maximum repeatable measurement error of the equipment is 0.000 49 N·m,which has good repeatability and meets the design requirements.
