Understanding the basics of gear trains is important. This apparatus ensures this is done in a simple, visual and durable way. A bench top frame of profiled aluminium, houses shafts which can be
moved within the grooves of the profile. The profile grooves ensure the quick and easy release and securing of the shaft and hence component parts. Onto the shafts sis bearings and the gear components themselves. The gears are manufactured from durable plastic and all other components are industrial standard parts. Rotation of the gear arrangements is done manually. The pitch circle diameters of the gears are visually shown also. A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
