Summary
KRL Tapered Roller Bearing method determines viscosity and shear stability of Transmission Lubricants,
This KRL Taper Roller Bearing Rig adopts LCD touch screen: through the screen, the oil sample temperature control, rotating shaft speed, test load, test time, shear revolution and other functions can be controlled. All key parameters and control points can be displayed at a glance, realizing a highly integrated and automated operation interface, which greatly reduces the operation difficulty of the experimenter.
I. Main technical features
1.This KRL Shear Stability Test Apparatus adopts double floating bearing technology, non clearance guiding technology and buffer cross balancing technology are adopted to ensure the precision of real-time tracking measurement of test force and friction force;
2.The brand servo motor is used to drive the spindle, and the relevant transmission components also use imported precision bearings;
3.This KRL Taper Roller Bearing Rig has independent embedded industrial controller, industrial metal touch screen and independent analysis module are adopted to effectively ensure the impact on the performance of the control part in case of high-speed equipment or severe vibration due to oil film rupture;
4.It can easily capture the wear spots, measure and analyze the friction surface morphology, and directly save the wear spot image;
5.The test software can establish professional test schemes according to different standards, and can also judge the Pb value according to the size of wear spots.
6.This KRL Taper Roller Bearing Rig has the function of saving and exporting data tables.
