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

This laboratory system is used to introduce combined drives and their correct assembly. The programme of exercises enables familiarisation with 6 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.
