belt pulley

Aluminium. Rim flanges, steel. Version Aluminium bright. Steel electro zincplated. Note Standard T profile acc. to DIN 7721 T2 with metric pitch (trapezoidal toothing). At least one belt pulley must have a rim flange. The toothed belt pulleys have a centre bore or a pilot hole (this can vary due to manufacturing methods). For this reason, the dimension D2 max. given in the table is the maximum diameter of the bore with which the toothed belt pulleys are supplied. This pilot/centre bore can be amended by the customer to produce a reamed bore, reamed bore with keyway or a tapped hole. Alternatively, customers can also use bushes to reduce the bore diameter.

It is similar to chain mechanisms in terms of its working principle, as it carries out motion transmission in a closed manner. In terms of materials, it is similar to belt-pulley mechanisms The conversion rate is fixed. The movement can be precisely synchronized as desired. Does not require lubrication. It gets very little hot during operation, It works noiselessly. It allows the use of very small diameter gears.

Standard Catalogue Product Range Pulley Diameters up to 800mm (32”) Belt widths up to 2,800mm (110”)

Our endless turned round belts are wound either out of one homogeneous strand or one cord and spliced endlessly without thickening. For special applications, it is possible to vulcanize the inner splice or to make a special splice based on our in-house engineering methods. This increases the tensile strength by up to 60%. In elastic types, the core is welded. In view of their special structure, twisted round belts exhibit very quiet running properties, are extremely flexible and, thus, make possible very small minimum pulley diameters of 3x belt diameter. For several types, speed up to 70,000 rpm is possible; however, the speed of 60m/s should not be exceeded. Elastic types: PU, Vulkollan Semi-elastic types: PA.6, Set-Polyester, Nylon, HE Types with limited extensibility: Polyester, Nomex, Nomex-PTFE, Polyester-PTFE, Kevlar/Twaron, PA.6 anti-static, PBO
