Control gears are also known as variable or change gears.They are characterised by the fact that the speed is transferred differentlyvia various pairs of gear wheels. The most famous example is the transmissionin a car, which has one pair of gear wheels for each gear. The unit providesdifferent configurations of control gears, which serve as an introduction togear engineering. The unit focuses in particular on the practical assembly ofgear components. The exercise system can be used to configure six differentgears in various combinations. The setup of the components is flexible so thatyou can configure your own ideas and try out different gears. Individualactivities such as understanding the task and reading the drawing, assemblingthe components, adjusting, calibrating and checking the gear, and performingcalculations are performed one after the other. The unit is driven by a handcrank. A solid frame made of square steel tubes and various bearings ensuressufficient accuracy to be able to set precise tooth interlocking. Allcomponents of the exercise system are ready at hand and securely housed in astorage system.
