HFN5 Journal Friction Apparatus Didactic Equipment Vocational Training Equipment Mechanical Training Equipment
Description This apparatus is designed to determine the friction torque in a plainjournal bearing under varying conditions of load, speed and lubrication.The ground steel shaft is driven by a variable speed electric motor. Thejournal housing has a thermometer pocket, a sight feed lubricator and aremovable end cover. Oil cannot be thrown out. Friction due to end facecontact is very much reduced by the use of a "floating" sleeve. Frictiontorque is measured by adding weights to a Load hanger suspendedfrom the damped torque arm. Weights added to the lower hanger applya steady load to the bearing of up to 650N. Phosphor Bronze, sinteredbronze and impregnated PTFE sleeves are supplied as standard journal housings. An electronic tachometer is provided for measurement of theshaft speed, which can be controlled using the control potentiometer onthe front control box. An oil drip tray is provided to ensure all oil passingthrough the journal bearing is captured. A full set of weights, hangersand tools is provided along with a comprehensive Instruction manual forstudent and lecturer Features Floor standing apparatus with levelling feet Three different Journal Bearings supplied Speed control and digitally displayed All parameters visible and controllable Ground Journal shaft Temperature measured Weights set supplied Technical Specification Shaft speed: 1500rpm Motor speed control potentiometer Drip feed lubricator for journal bearing lubrication Torque arm lever 4 : 1 ratio Journal shaft: Steel, Ø40mm nominal Journal bearings; Outside diameter = Ø50mm, inside diameter =Ø40mm Weights & Dimensions Weight: 32kg Length: 560mm Width: 480mm Height: 1000mm
