Friction testing machine

hydrostatic pressurehydrostaticwear

It is mainly used to measure the friction and wear life of various spherical plain bearing’s liners under the working condition of radial&axial alternating loading and swinging. It can be equipped with various environmental devices, like high temperature furnace, low temperature furnace, water spraying device and powder spraying device, etc as the simulation testing for bearings. 02 Product Characteristics Servo actuator It is composed of hydraulic cylinder, load sensor, displacement sensor, accumulator and servo valve, etc. The guide sealing elements of hydraulic cylinder plug and piston rod are all imported seals. Swing actuator It adopts double blade structure, front flflange installation; with features of low friction, low damping, high frequency response and good lateral force resistance; the swing actuator uses static pressure bearing technology, with features of wide temperature range, high bearing capacity, no crawling phenomenon at low speed. Hydrostatic support linear actuator (optional) New electro-hydraulic servo products with hydrostatic bearing and coating technology are used for testing the high precision static/dynamic material and components and other complex mechanical testing. 03 Working principle Using the electro-hydraulic servo closed-loop principle, all servo actuators are made with non-metallic friction. It has the characteristics of fast response, high precision, wide frequency band and various waveforms (sine wave, triangle wave, oblique wave, combined wave). It can stably and reliably carry out the testing of force (torque) and displacement (torsion angle) control.
