broad scope of learning with interdisciplinary problems

 Description:

• Planetary gears transmit and often increase torque while reducing speed at the same time.
• They are often used in wind power plants and as automatic transmission in automobiles.
• The MT 122unit is a single-stage planetary gear unit with three planet gears.
• The sun wheel is driven. The hollow wheel (also known as ring gear) is fixed.
• The MT 122kit is part of the GUNT-Practice Line for assembly, maintenance and repair, which has been designed for technical colleges and company training centres.
• The close link between theory and practice-based learning content is evident.
• The assembly and disassembly processes can be completed easily within standard lesson times.
• Only basic tools are required for assembly, all of which are supplied with the kit.
• The fit seatings of the gear unit are designed to allow the complete assembly process to be performed by hand.
• The contemporary multimedia instructional materials provide extensive technical information that provides the basis for lesson design.
• The core element of the teaching materials is a complete set of drawings as files with lists of parts, single-part drawings, exploded views, assembly drawings and 3D drawings.
• All drawings are to standard and are dimensioned in accordance with production requirements.
• The set of drawings consists of DXFfiles, STEP files and PDF
• Assembly videos are also useful features.
• The files are also available free of charge online in the GUNTMedia Center.
• The disassembled planetary gear with set of small parts and 4 assembly jigs are delivered in a storage system with foam inlay.
• The transport roller MT 120.02or the trolley MT 120.01 are suitable for convenient transport of the kit.
