Using a larger diameter minimises the bending stress in the belt and allows the use of a narrower belt. Belt Width - It is...

H T D T I M I N G B E LT S HTD Timing Belt Drives have a positive locking profile which ensures slip-free transmission of motion between the driving and driven pulleys. Low belt tension and low friction operation minimise energy loss providing high efficiency motion transfer. Other key features of the HTD belt system are: • Low belt tension and bearing load • Wide power / speed range • Low maintenance • Small space requirement • Smooth constant running speed • Suitable for very low as well as high speeds Use matching pulleys on pages 84 - 86 Pitch : Width 9mm Order Code Width 15mm Order...

PULLEY CLAMPING ELEMENTS D This keyless shaft-pulley connection eliminates play between the shaft and the hub and distributes the power transmission over the entire surface whereas with a key connection, the transmission is concentrated on a limited area only. This allows savings in materials because the shaft diameters can be designed smaller and making these elements ideal for heavy transmissions, with overload or continuous reversing, or where required, with more hubs mounted on a single shaft. Simple mounting and dismounting means easy and quick changing on the shaft; the high pressure...
