Pulleys or synchronising pulleys are used with drive solutions with timing belts. Transmission accuracy, service life and also smooth and quiet running are crucially influenced by the precision of the interaction between the timing belt and the pulley. Synchronous pulleys are classified according to the defined standards of the timing belts, number of teeth, pitch, pulley width and abbreviation for the model.
The selection of the correct tooth gap shape is crucial for the accuracy of the overall timing belt system. The smaller the “gap” between the timing belt and synchronising pulley, the greater the benefits for linear drives and systems with exact positioning and repeat accuracy.
Please refer to the respective data sheet for more detailed properties of the individual components.
AT
The AT profile is a further development of the standard T profile and, in particular, provides higher tooth strength resulting from the larger tooth volume and stronger tension members.
Benefits:
- Favourable tooth mesh
- Up to 50% improved performance over the T profile
- Precise transmission of movement
