Timing belts use teeth that mesh with grooves in a pulley to drive the system. There is no slippage, which will cause speed variations, allowing drives to be timed very accurately. The tensile cord, which could be made of many materials; Fibreglass, Steel, Carbon Fibre, or Kevlar, has minimal stretch so the constant need for take up adjustment is removed. Unlike chain drives no lubrication is required on timing drives so maintenance is again reduced. Chain drives require some form of lubrication, be it drip, splatter or fully enclosed oil bath. With timing belt drives this is not required, saving on the initial set up cost of NOT installing a lubricating system but also the cost of maintaining it.
