Fastener friction coefficient testing machine

Product introduction

1, the fastener friction coefficient tester is mainly used for the testing and analysis of bolts, screws and nut fasteners. By applying the tightening torque to the bolt-nut connection pair to generate the clamping force, its fastening characteristics can be measured, such as clamping force, fastening torque, thread torque, support surface torque, total friction coefficient, support surface friction coefficient, thread friction coefficient, torque coefficient K, etc. Widely used in aerospace, universities, research institutes, quality inspection, automobile, rail transit, wind power and other fields.

2. The mechanical system is composed of working platform, Panasonic servo motor and reducer, high-precision dynamic torque sensor, static compression and torsion composite sensor, fixture and guide rail. The loading mechanism is driven by the servo motor reducer to apply torque to the sample, and the torque value and tightening load of the sample are measured by the sensor, while the torsion Angle is detected by the photoelectric encoder, and the detected signal is transmitted to the measurement and control system to complete the measurement of the sample torsion index and the drawing of the curve.
