Why fit a belt drive?
– Drive belt technology has progressed enormously over the last thirty years.
– Greater efficiency – typically up to 98%.
– A very noticeable reduction in noise and vibration.
– Reduced weight.
– Complete elimination of clutch slip.
– Complete absence of oil leaks – due to the elimination of oil.
– Improved gear tooth life – due to the elimination of high frequency shock loads which a traditional drive chain transmits, and the increased rotation speed of the gearbox effectively dividing the loads through a greater number of teeth.
– A much lighter lever action, if using a belt drive with a diaphragm spring. Coil springs get progressively heavier while compressed diaphragm springs do the opposite).
