GL 430 Assembly control gear

FEATURES:

 

  • Flexible and robust assembly system for mechanical drive systems
  • Practical orientation based on use of standard components
  • Quick and easy assembly with no jigs and fixtures, just simple tools
  • Safe drive with hand crank
  • Comprehensive well-structured instructional material

DESCRIPTION

Technical Description

This laboratory system is used to familiarise students with the design and correct assembly of step and shift gears. 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 setup 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 storage system.

The multi-step and shift gears in GL 430 are based on those of a conventional lathe. The step gear unit is very similar to the primary drive on a pillar drill. 

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.
