Timing belt pulleys are largely used for different applications. Karls has been dealing with timing belt pulleys for a long time and has always met the raising demand of its customers. Many timing belt pulleys are available ex stock according to the belt they are matching to ( according to pitch, width and form of toothing). The materials used depend on the dimension and type of Pulleys and are showed in the following list.
Tooth belt pulleys are generally made of steel, cast iron (GG) or aluminium. Pulleys are also available in other materials such as plastic or stainless steel for specialised applications. Of course, it is also possible to apply a particular surface treatment to the pulleys if the ambient conditions require it.
Several factors determine which toothed belt type is best suited to a particular drive, for example the application (what is being driven?), the power to be transferred, the desired speed (acceleration or deceleration) and the centre-to-centre distance between the pulleys. It is also important to know what ambient conditions are present and whether there are any space limitations (what is the maximum permissible diameter and width of the pulleys?).
Common standards for toothed belt drives are DIN 7721 and ISO 5294. Finally, it is important to consider whether the drive needs to be static-conductive to meet ISO 9563 (ATEX environments).
