Keeping things moving. Page 2 May 2008 The production of synchronous pulleys is subject to a constant quality control. Generally, the synchronising pulleys are hobbed. Optimum function is reached by precisely designing tooth gaps and pitch uniformity. Material and dimensions of the synchronous pulleys, such as number of teeth, pulley width, hole and fl ange arrangement. In the following please fi nd information for the planner and designer. Materials Aluminium: or normal requirements we recommend the light metal alloy AlCuMgPb (F 38). This material is also used for the production of synchronous...
