Abstract
A device for measuring a diameter error of a roller for threaded pair transmission in the technical field of power machinery, comprising a roller fixing device, a laser measuring device, a screw driving device, and a roller to be measured. The roller fixing device comprises a fixing rod, a supporting structure, guide rails, nut-bolt pairs and a fixing beam, to fix the roller. The laser measuring device comprises pressing columns, laser sensors, laser receiving plates, laser sensor placement plates and moving structures, which ensure the verticality of the roller. The screw driving device comprises ball screw pairs, bearings, nuts, nut connecting bolts and cranks, to drive the moving structures to ensure the distance between the laser measuring device and the roller. The roller diameter error measuring device of the present disclosure is simple to operate, has fewer human influence factors, and has high measurement accuracy.
