Polyurethane Synchronous Drive Belts CONTI SYNCHRODRIVE® Synchronous drive belts CONTI SYNCHRODRIVE® Belts for synchronous transmission of rotary and linear motion CONTI SYNCHRODRIVE® belts are power transmission products made from a highly durable polyurethane elastomer incorporating a steel-cord tension member. They are manufactured precisely to length using a newly developed production technique. CONTI SYNCHRODRIVE® belts can be used in the openended or endless form. In all cases, they ensure that rotary motion is transmitted uniformly and with angular precision. CONTI SYNCHRODRIVE® belts permit...

Polyurethane Synchronous Drive Belts Pulleys Precise belt/pulley conformance is vital to ensure accurate power transmission as well as smooth operation and a long service life for synchronous belt drives. ContiTech engineers have modified pulley tooth-gap profiles so that they conform ideally to the respective belt profiles. Use of these optimized pulleys is recommended especially for CONTI SYNCHRODRIVE® HTD belts. Pulleys with optimized profiles are obtainable from your Mulco sales partner. Linear drives with demanding positioning requirements need pulleys with minimized gap clearance. If you...

CONTI SYNCHRODRIVE® Minimum number of teeth Drives fitted with CONTI SYNCHRODRIVE® synchronous drive belts should have pulleys that meet the specified minimum number of teeth. Table 6 shows the minimum number of teeth zmin and the minimum pitch diameter dw min for pulleys as well as the minimum diameter dmin for inside and outside idlers that are to be considered when designing a drive. Inside idlers should be toothed pulleys. Table 6 Minimum number of teeth / - zmin HTD Tooth profile Minimum number of teeth zmin Type Minimum pitch Ø dw min Type Minimum Ø of idler dmin Type inside outside Minimum...
