GL 420 Gear Assembly Unit: Combined Drives Show data sheet (pdf file) Print page
Technical Description

  This laboratory system is used to introduce combined drives and their correct assembly. The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations.
  The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas.

  A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing. All the system components are kept ready to hand and well protected in a housing system.
  GUNT offers three kits in this product series, each focussing on different aspects: GL 410, GL 420 and GL 430. Each kit is used entirely independently of the other kits within the series.
