HTD - RUBBER TIMING BELTS
Rubber Timing & Friction Belt Drives
HTD Rubber Timing Belts
HTD Rubber belts
The HTD timing belt drive is an advancement on the
Imperial trapezoidal toothform, resulting in a more uniform
transmission of power when the teeth are in mesh.
With better transfer of belt tension to the tension cords, a
more uniform distribution of stresses within the tooth profile,
the belt design results in increased torque transmission.
Small Centre Distance
High strength and flexibility allows the use of small
pulley diameters, low centre distances and reverse
bending idlers. High quality pulleys with pilot bored or
taper lock design enable a low-cost, readily available
drive setup, with less space requirement.
High efficiency
The superb flexural properties of the synchronous drive
belt, as well as the exact dimensional mating of the
belt and pulley tooth contours, permit drives with an
efficiency of 98%.

teeth and backing
The teeth and the belt top are made from high strength
Polychloroprene based elastomer materials. A special
manufacturing process ensures an excellent adhesion,
both on tensile member and on the facing fabric.
Glass tension member
Timing belt drives call for a high degree of length
stability and tensile strength. The HTD belts have a
low-elongation tensile member of Glass cord helically
wound in opposing pairs over the entire belt width.
Polyamide fabric
Durable teeth protection is provided with an
abrasion-resistant Polyamide fabric, with a low
coefficient of friction.
