Dynamic friction in pin - disk Investigations into wear on pairs of friction materials with surface contact Features - frictional forces between two sliding friction pairs - investigation of wear - use of different lubricants possible Learning objectives/experiments - together with the drive unit -- frictional forces in different friction pairs and loads -- frictional forces with different lubrication -- frictional forces at different relative speeds of the friction partners -- wear under different friction parameters and lubrication conditions Specification [1] frictional forces in pin and disk, which slide against each other, disk subjected to axial load [2] quick and easy assembly of the experimental unit on the frame of the drive unit [3] disk is driven by a clampable coupling between drive unit and gear unit [4] fixed pin made of different materials: aluminium, brass or steel [5] rotating disk made of hardened and ground stainless steel [6] load on the pin via lever arm and stepped weights [7] use of different lubricants, e.g. water or oil [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 Disk - Ø=50mm - hardened stainless steel, ground Pin, ØxH: 4x25mm - 3x aluminium - 6x brass - 6x steel Force sensor for frictional force - 0...50N Weights - 1x 5N (hanger) - 1x 20N - 1x 10N - 1x 5N LxWxH: 350x430x230mm Weight: approx. 8kg
