Brief introduction: This machine can do lubricant long wear resistance test, the determination of the coefficient of friction, the friction force and temperature curve. The machine is equipped with a high precision measuring device, to measure the friction pair grinding spot size, or implement grinding friction pair of computer screen display, measure and record. Four-ball tester, is in the form of sliding friction under the condition of high contact pressure, it is mainly used for evaluation of bearing capacity of lubricant. Including maximum no card bit load Pb, Pd, sintering load ZMZ composite wear value of three indicators, in practice, according to the various purposes of lubricant choose different evaluation indexes. Technical parameters: The biggest test (kN) : 10 Test force measuring range: the maximum test force of 0.06% 100% Test force relative error value: plus or minus 1%, under 400 n + / - 5 n Test force long stay: of error of plus or minus 1% FN (per) The friction measurement range (N) : 0-300 Single-stage infinitely variable speed system (r/min) : 200 ~ 3000 Spindle speed error (r/min) : 10 mm The friction load sensor (N) : 50 The oil box of stroke (mm) : > 45 The spindle hole taper: 1:7 The heater temperature scope of work (℃) : at room temperature to 220 The temperature control range (℃) : 2 or less Special standard ball diameter (12.7 mm:) phi The spindle motor power (kW) : 2.2 Machine spindle control: time control speed (cycle) friction control Machine appearance size (mm) : 1200 * 810 * 810 Testing machine quality (kg) : 850
