V-belt torque fatigue testing machine

VNP-02B typeV-belt torque fatigue testing machine

I. Overview

VNP-02B typeV-belt torque fatigue testing machineIt is designed and manufactured based on the wheel drive belt (with torque) fatigue testing machine of Shaw Company in Germany, combined with standards such as GB/T12735-2014 "Fatigue Test Method for V-belts Used in Agricultural Machinery", HG/T2819-2010 for narrow V-belts, HG/T3745-2011 for ordinary V-belts, and GB/T10821-2008 "V-belts and Multi Wedge Belts Used in Agricultural Machinery". The experimental process is controlled and calculated by a computer, with a frequency converter and a DC controller driving and regulating the speed of the motor, respectively. The test specifications comply with the requirements for the use of two wheel test and four-wheel reverse bending torque fatigue test in GB/T12735-2014 "Fatigue test method for V-belts used in agricultural machinery".
