description

This benchtop unit is based on the vertical combination of a threaded spindle and a nut. It contains two spindles with trapezoid threads and varying lead. To match these spindles, three long nuts made of different materials with single lead, and a cast iron nut with a double lead are provided. A spring balance with a nylon cord enables a turning moment to be exercised on the spindle using a pulley. Additional weights can be placed on the rotating plate to change the axial load on the thread. The thread efficiency can be determined and compared using the measured values. The unit is portable and is equipped with anti-slip feet to ensure that it remains stable. The painted metal base plate is fitted with clips for the individual parts.
