determine the thread efficiency with different thread-material pairings

 Description:

• The main elements of this experimental unit are a perpendicular pair of thread spindle and nut.
• A moment is exerted on the spindle by means of a pulley, using a spring balance and cable.
• Additional weights on the rotary plate influence the axial load of the thread.
• Two spindles with trapezoidal threads of different pitch are included.
• The experimental unit contains three long nuts made of various materials with single pitch and a cast iron nut with double pitch.
• The measured values can be used to determine and compare the threads efficiencies.
