Custom Made Timing Belt Pulleys
Timing Belt Pulleys are used with all types of HTDHigh Torque Drive
Because of its tooth height and semi-circular tooth geometry, the HTD profile is especially good at avoiding jump-over of the teeth in operation. The HTD profile is extremely suitable for transmitting high torques., STDSuper Torque Drive
The involute shape of the STD profile allows optimal tooth engagement with the pulley. As a result, it provides precise and quiet operation even at high belt speeds., CTDConti Torque Drive
The CTD profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running., GTRThe GTR profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running. It also incorporates an additional groove in the tooth head, which enables the air to escape gently from the tooth gap, further enhancing its smooth running., H.O.T.Helical Offset Tooth
The helical toothing of the H.O.T. profile delivers a degree of operational smoothness unrivaled by other timing belts The noise level can be reduced by up to 19 dB, and the polygon effect is almost eliminated, resulting in up to 20% lower vibrations. The profile’s offset toothing means the belt is also self-tracking: Flanges are not necessary, as a result of which the width of the system can be reduced., TTrapezoidal/Trapezprofil
The T profile is a trapezoidal standard profile in a metric pitch for conventional timing belt applications. The tooth geometry allows a play-free belt/sprocket pairing that results in unsurpassed precision. and ATThe AT profile is a further development of the T (Trapezprofil) profile. The teeth have a higher load capacity because of the increased tooth volume. The optimized flank angle results in improved tooth meshing. Here, too, a play-free belt/sprocket pairing that results in unsurpassed precision can be achieved. timing belts and timing belts with trapezoidal inch profile. The basic types of pulleys are made of steel, cast iron or aluminium alloy in a design with a cylindrical bore with a keyway, as pulleys for Taper Lock bush or according to another design. As a semi-finished product for further modifications, it is also possible to produce pulleys with a basic cylindrical bore.
They can also be custom made from other materials or according to drawings and special customer requirements.
Timing Pulley Types Overview
| Pulley Type | Description | Illustration |
|---|---|---|
Solid Timing Pulleys with Hub and 2 Flanges |
Solid pulleys are machined from solid material or manufactured as castings. They are suitable for use with small dimensions. Aluminum alloy is often chosen as a material when a lower weight is required. The flanges serve to guide the timing belt and prevent it from sliding off the pulley. |
 |
Solid Timing Pulleys with Weight Reduction |
Solid pulleys are machined from solid material or manufactured as castings. Design reduces weight, although the pulleys still have a compact shape. They are suitable for use with small and medium dimensions. They can be, for example, with a cylindrical hole or in a design for Taper Lock conical bushes. |
 |
Timing Pulleys with Round or Shaped Holes |
Pulleys with shaped holes produced as castings are suitable for medium and large dimensions. Design with shaped holes reduces weight, although the pulleys still have a compact shape and are suitable even for high speeds. |
 |
Timing Pulleys with Lugs |
Pulleys with lugs are produced as castings and are suitable for medium to largest dimensions. Design with lugs significantly reduces weight. Caution – pulleys are only suitable up to a certain speed (most often up to 30 m/s). At higher speeds, the pulley may break and rupture. |
 |
Special Timing Pulleys |
Special pulleys are manufactured as castings or workpieces. They are used in cases where it is not possible to use conventional constructions or their special design is required. These are most often complex medium to largest pulleys. |
 |
Pulleys Fields of Use
The timing pulleys are designed for all types and profiles of timing belts.
They are typically used in machine tools, small machinery, conveyors, compressors, packaging and printing machines, in the food, automotive, paper and chemical industry and in many other machines.
Pulleys Material
Steel, cast iron, aluminum alloy, stainless steel, plastic or other materials of adequate strength.
