MT 110.02 Assembly spur wheel / worm gear mechanism
The MT 110.02 unit deals with a two-stage gear. The kit contains all the individual parts to build the gear. The gear comprises a spur gear stage as its input, with a downstream worm gear stage (combined gear). The fit seatings of the gear unit are designed to allow the complete assembly process to be performed by hand. All parts are laid out clearly and are well protected in a sheet-steel tool box. Small parts are contained in a box with a transparent lid. A set of tools is included.
The project-based nature of this assembly kit allows for varied and above all interdisciplinary work in the classroom. The project is particularly recommended for a practical-based teaching organisation, in conjunction with independent student activity and teamwork.
The contemporary 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 with lists of parts, individual part designations, exploded views and assembly drawings. All drawings are to standard and are dimensioned in accordance with production requirements. Pdf files and assembly videos are also useful features.
The fully assembled gear can be tested for functionality using the optionally available MT 172.
