Product Description

Spur Wheel Worm Gear Mechanism     

Technical Description of Spur Wheel Worm Gear Mechanism    

The 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 team working skills, ensures that the unit serves as an excellent learning tool.
