HFN9 Friction Of Belts Apparatus Didactic Equipment Vocational Education Equipment Mechanical Training Equipment
Description The apparatus consists of a wall mounted pulley with a loaded belt. Thepulley is made of aluminium and has two machined grooves to suit aflat, vee belt, and a rope. Each belt fits into its respective groove duringtesting. For a given belt tension and angle of lap, a turning moment canbe applied by adding weights to the pulley drive hanger. The idea is todetermine the torque which just causes the pulley to turn, and so to findthe ratio of the belt tensions. This enables the belt tension equation tobe verified and the coefficient of friction to be determined. The angle oflap can be easily varied by placing one end of each belt at differentangular positions on the wall bracket. A removable pin and bar are usedto enable the various angular positions to be achieved Features Sturdy Wall mounted apparatus Can be mounted to HST1, HST100, HAC14, HVT12f frames One pulley caters for three belts. No interchanging of pulleys Constant tangential drive of pulley Three belts supplied; flat, vee, rope Customer specific belts can be used Full set of weights and hanger supplied Technical Specification Single large pulley Flat groove and 40° 'V' groove 150mm effective groove diameter Pulley timing grooves at 18° intervals Belt anchor points at 15° intervals Safety interlock to stop pulley rotating Weights & Dimensions Weight (excluding set of weights): approximately 10kg Length: 230mm Width: 150mm Height: 280mm
