Broekema - Sprocket and Drive Wheels
We manufacture a complete product line of drive wheels for any kind of belt drive designs which are common in harvesting applications. It is important that the belting’s operational characteristics and the type of belt drive are matched for optimum conveyor reliability and rod life.
Cast iron forms the heart of all drive options. Most sprockets and drive wheels are splittable to facilitate mounting & replacement. Wheel halves are matching pairs and must not be mixed. Our drive wheels are supplied bored & keyed to your specification and as required, with one set screw over the key way, optionally also at 90 degrees. We can also supply a ‘raw bore’ to be machined by yourself. Clamp fit: Only possible with splittable types. Hub is slightly under bored, plus 1 or 2 optional set screws. Practical when drive shafts are of reasonable close tolerance. Keyway types and sizes are cut to German DIN (metric) or imperial standards. Friction drive types FR, FRD and KW can be used with any belt type and pitch. Minimum-maximum bore size is indicated in each type´s data sheet. Ideally relate to the most popular standard hub types.
