Helical-worm gear unit cut-away model

Bring your theory to life. Our cut-away model shows how the internal components of a helical-worm gear unit interact and how a gear unit works.

By means of a handwheel on the cut-away models, we aim to demonstrate the interplay between different gearing as well as the resulting flow of forces and gear ratios.

Every cut-away model features a nameplate showing the most important data. This can be used to practice calculations, such as determining gear ratios and speeds.

As an option, the cut-away models can be securely stored in TANOS (T-Loc) case systems.

The gear unit modules have been designed solely for educational use.

Areas of application

The kit and helical-worm gear unit cut-away model are suitable for use in education and further training at

  • Vocational schools
  • Technical schools
  • Specialist schools
  • Colleges
  • Universities
  • Company training establishments
  • Etc.
