base module for studying various cases of sliding and rolling friction

Description:

• Tribology studies friction, wear and lubrication.
• Friction occurs when two solids are in contact with each other and their movement is impeded.
• If material is lost progressively during this process, it is referred to as wear.
• Lubricants are used to minimise friction and wear.
• The TM 260drive unit, together with the experimental units TM 260.01 to TM 260.06, offer a complete course with a series of experiments to study tribological phenomena.
• Various rolling and sliding cases can be demonstrated in the classroom or studied in the laboratory.
• The parameters of a tribological system are recorded and analysed.
• A comprehensive range of friction pairings makes it possible, among other things, to represent how the frictional force is independent of the contact area.
• The TM 260units comprise a frame on which the drive unit is mounted together with an experimental unit and a display and control unit.
• Quick-action chucks make it quick and easy to assemble.
• The drive unit has a pivotable motor block bearing.
• This allows the drive shaft to be installed horizontally or vertically.
• The speed of the DC motor is continuously adjustable and is detected by means of an incremental encoder.
• The frictional forces are measured by a force sensor in each experimental unit.
• The display and control unit shows frictional force and speed, the latter of which can be adjusted continuously.
• The following experiments can be conducted: Rolling friction in friction wheels (TM 260.01), Elasto-hydrodynamic behaviour (TM 260.02), Dynamic friction in a pin on a disk (TM 260.03), Frictional vibrations (TM 260.04), Dynamic friction in a cylindrical pin on a roller (TM 260.05), Pressure distribution in journal bearings (TM 260.06).
