TM 260.01 Rolling Friction In Friction Wheels Didactic Equipment Vocational Education Equipment Mechanical Training Equipment
Slip forces in two discs rubbing together Features - frictional forces between two rolling friction wheels - how slip affects the frictional force - use of different lubricants possible Learning objectives/experiments - together with the drive unit -- determine the frictional forces as a function of load, lubrication and operating speed -- how slip affects the frictional force -- determine the coefficients of friction Specification [1] frictional forces in two rolling friction wheels [2] quick and easy assembly of the experimental unit on the frame of the drive unit [3] driving wheel is driven by a clampable coupling between drive unit and gear unit [4] slip between friction wheels kept constant at 4% by means of gear unit [5] load on the friction wheels via lever arm and stepped weights [6] friction wheels materials pair: aluminium/rubber [7] use of different lubricants [8] frictional force measured by force sensor [9] displays of force and speed and speed adjustment on the drive unit Technical data Load application device - max. load: 80N - lever arm ratio: 2:1 Friction wheels - Ø=49mm - Ø=45mm, incl. rubber ring Gear ratio - i: 0,96, slip approx. 23% Force sensor for frictional force - 0...50N Weights - 1x 5N (hanger) - 1x 5N - 1x 10N - 1x 20N LxWxH: 480x250x150mm Weight: approx. 7kg
