Toothed belt


The toothed belt is maintenance-free and runs very quietly. No lubrication and retensioning is required.

However, the profile pitch has to be very precise as the meshing is form-fit with the profile of the drive head. Otherwise the service life of the toothed belt will be dramatically reduced. The tolerances for the holes differ immensely among the toothed belt manufacturers. Interroll therefore recommends obtaining precise tolerances from the manufacturers.

The toothed belt is only used infrequently in container conveyor technology as its efficiency is relatively poor, due to the construction of the belt, and a large proportion of the driving power is used by the belt. Toothed belt drives are primarily used in the conveyance of pallets or in the automotive industry for the transportation of special carriers. The poor efficiency of the belt in relation to the total drive power is relatively immaterial in these instances.

The toothed belt is fundamentally unable to negotiate curves.

Tangential drive

Tangentially the toothed belt should only be used for relatively low levels of power. It is essential to ensure that a special guide presses the belt securely onto the drive head. When used tangentially, the level of efficiency of the toothed belt is significantly higher than when used in roller-to-roller applications.

Roller-to-roller drive

Toothed belts are primarily used with roller-to-roller drives. High torque can be achieved at high speed with these drives. The disadvantage with these drives is their susceptibility to dirt and the essential requirement relating to the precision of the hole in the side profile.
