Cutaway model: planetary gear (GL 300.05)

Cutaway model: planetary gear (GL 300.05)

demonstration of complex machine elements and demonstration of their principle of operation

Code GL300.05


  • Using cutaway models, it is possible to clearly demonstrate the operational principles of complex machine elements such as a multi-disc clutch, various gearboxes or a pedestal bearing.
  • The GL 300.01to GL 300.12 cutaway models form a meaningful addition to the assembly kits, models and model kits for the engineering drawing discipline.
  • In order to be able to use the cutaway models in engineering teaching, each model comes with a standards-compliant and practical drawing and a technical description.
  • Problems of engineering drawing, fasteners and machine parts or production and testing technology can be studied in a clear and practical manner using the cutaway models.
  • The cutaway models represent original components in which the active parts are clearly visible to the user while fully maintaining their mechanical functionality.
  • Each of the cutaway models is securely mounted on a base plate, which also has handles to allow them to be carried.
  • They are powered by hand.
