Timing belt pulleys

End-to-end product rangeMulco supplies a complete range of pulleys and other components carefully integrated with their entire portfolio of timing belts. The standard stock range includes more than 3,500 different pulleys, tensioners, tension plates, clamping plates, and guide rails. Almost any combination of materials - be it aluminum, conventional steel alloys, stainless steel or plastic materials - can be turned into high-quality belt drive components. Surfaces are treated by anodizing, hard anodizing, hard coating, galvanizing, burnishing, phosphating, plasma plating, nitro-carburizing and other common methods.

Off-the-shelf and fully customized productsTiming belt operation is significantly impacted by the qua-lity of the pulleys. Technically speaking, volume production of the standardized Mulco range of pulleys is therefore just as sophisticated as the design and production of pulleys and components to customers specifications. Thus, this strategic commitment not only relies on high-levels of qua-lity but also on fast delivery - worldwide.

Mulco belt-pilotOur interactive Internet programme enables you to gene-rate your personal design solutions online. Whatever field of technology you are interested in - power transmission, linear, transport or components - use Mulco belt-pilot at www.mulco.net for 24/7 access to the actual product in for mation, CAD downloads and calculations you need.

High quality standardsMulco‘s factories manufacturing pulleys and components rely on the latest-generation Profilators. High precision, flexible manufacturing and fast throughput are ensured by machines with automatic feeders able to take multiple process steps, i. e. polygon machining, spline cutting or tooth shaping machining, to 1/100th of a millimetre accu-racy. Downstream measurement from simple inspection of finished parts to modern conturoscope scanning (at a resolution of 1/1000th of a millimetre) to 3D measuring equipment make sure that the exactly defined quality standards are met. All pulley manufacturers contributing to the Mulco range are certified according to DIN EN ISO 9001:2000.

Selecting a special pulley tooth gap can increase the accuracy of the timing belt system by decreasing or elimi-nating “play” between the timing belt and the pulley. Linear drives and systems requiring precise positioning and high repeatability or fast settling times can benefit from reduced

Flanges

Zinc plated steel is used as the standard material. Special versions to user requirements.

Mounting is achieved by rolling, crimping or screwing depending on the tooth profile and number of teeth.

The belt width b is dependent on the pulley width B to guarantee sufficient width clearance. This clearance is not dimensioned separately.

Ordering information

The production of timing pulleys is subject to a continuous quality control. Timing pulleys are generally hobbed. Optimum function is reached by precisely generating toothforms and achieving pitch uniformity.

The material and dimensions of the timing pulley such as number of teeth, pulley width, bore and flange arrange-ment are defined by the customer. Below, recommenda-tions for the designer can be found.
