Synchronous drive belts are the composed of: Positive Drive System Without Slippage Low Synchronous Drive Belt Tension
– Teeth and belt top of polychloroprene
– Polyamide fabric (facing fabric)
– Glass tension cords.
Teeth and Belt Top of Polychloroprene
The teeth and the belt top are made from highly loadable polychloroprene based
elastomer materials. A special manufacturing process ensures an excellent
adhesion both on the tensile member and on the facing fabric.
Polyamide Fabric
A durable protection of the teeth is an essential precondition for a smooth
operation and a long service life. This is ensured by the application of particularly
abrasion-resistant polyamide fabrics with low friction coefficients.
Glass Tension Cords
Synchronous belt drives call for a high degree of length stability and tensile
strength. These requirements are optimally met by low-elongation tensile members
of glass cord helically wound over the entire belt width. Any longitudinal
off-track running will be largely prevented by the use of tensile cords twined in
reversed lay in pairs.
Further design features:
– High resistance to fatigue failure
– Temperature and ageing-resistant
– High resistance to tearing.
In the same way as with a gear drive, the belt's teeth mesh with the toothing
of the drive pulleys. The special tooth profile of belt and pulleys guarantees a
precise synchronism and a high degree of safety against tooth jump.
High Power Output
The rounded HTD tooth profile combined with the wear resistant facing fabric as
well as with the high dynamic load-bearing capacity of the tension cord ensures
operating efficiency
HTD synchronous drive belts render possible a positive transmission of power for
high torques in such fields of application where only chain drives or gears drives
have been made use of to date.
Minimum Space Requirements
The high power output renders possible the design of heavy-duty drives with
compact construction and a low weight.
Extensive Speed Range
The high strength of the belt teeth as well as the excellent flexibility of the
synchronous drive belts render possible operationally safe and reliable drive
versions in the lower speed range and at belt speeds up to 50 m/s.
The positive transmission of power requires only low initial tensioning. The HTD
tooth profile guarantees a high degree of safety against tooth jump. So the axle
and bearing loads stay low.
No Lubrication and Maintenance
HTD synchronous drive belts are free from maintenance:
no lubrication and re-tensioning required. HTD synchronous drive belts are
insensitive to corrosion and stable in length.
Low-Noise Running
The flexible synchronous drive belt construction, the frictionless meshing of the
teeth and the combination of fabric-faced rubber teeth with toothed pulleys of
metal or of synthetic material reduce the running noise to a minimum.
High Efficiency
The flexible synchronous drive belt construction as well as the exact dimensional
match of the tooth profile of the belts and pulleys allow drives with an efficiency
of 98%.
HTD synchronous drive belts of the standard version are:
– oil resistant to a degree
– tropics-resistant
– remain stable over a temperature range from –20 Degrees Celsius to 100 Degrees Celsius according to
application
– ozone-resistant
– insensitive to weathering.
