DESCRIPTION
Technical Description
The MT 110.02 two-stage gear unit kit contains all the parts required to construct the gear unit. It consists of a spur gear stage as its input, with a downstream worm gear stage (multistage gear combination). The fit seatings of the gear unit are designed to allow the complete assembly process to be carried out by hand. All parts are clearly laid out and well protected in a sheet-steel tool box. Small parts are supplied in a box with a transparent lid.
This assembly exercise permits wide-ranging and, above all, interdisciplinary work to be carried out by the students. The project unit is particularly well suited to action-based teaching. This, in conjunction with students working in an independent capacity, as well as developing teamworking skills, ensures that the unit serves as an excellent learning tool.
The modern style used in the instructional materials outlines comprehensive and in-depth technical information which forms the basis for the teaching process.
The teaching material includes a complete set of drawings with parts lists, single part drawings, an exploded view and assembly drawing. All drawings are to standard, and dimensioned in line with production requirements. Another very useful feature is the extensive set of transparencies for the overhead projector.
A tool kit is also included. The fully assembled gear unit can be function tested together with the optionally available MT 172 unit.
Learning Objectives / Experiments
- design and function of a multistage gear combination
- reading and understanding engineering drawings
- familiarisation with component and assemblies, their design features and functions
- dimensioning exercises, gauging of parts
- work planning, particularly planning and presentation of the assembly process
- familiarisation with assembly aids and jigs
- assembly exercises: component and complete unit assembly
- analysis of faults and damage, in conjunction with maintenance and repair steps
- material selection criteria
In conjunction with MT 172
- functional testing of the assembled gear unit
