Example Embodiment
[0048] Such as figure 1 , 2 , 3, the screw drilling tool rotor coating friction test device, mainly includes frame, box, grinding wheel assembly, linear rail assembly, linear motion assembly, pressure assembly, reducer with motor, linear motion assembly drive mechanism .
[0049] The box body 2 is fixedly arranged on the frame 1. The tank body is used to hold mud liquid.
[0050] The grinding wheel assembly includes a main shaft 3 and a grinding wheel 4. The two ends of the main shaft 3 pass through the left and right sides of the box body 2 and are supported by bearings 5. The box body 2 is provided with an end cover 6 at the position where the main shaft 3 passes, and a sealing ring 7 is provided between the end cover 6 and the main shaft 3 to prevent the mud liquid from leaking and entering the bearing and causing damage to the bearing. There are multiple grinding wheels, and the multiple grinding wheels 4 have the same diameter and are all fixed on the main shaft 3. At leas...
