V-BELTS Rubber V-belts

PLATINUM
Megadyne proudly introduces the new PLATINUM timing belt drive, the latest development on hi-performance systems,
which significantly improve the “specific power“ capacity and offer new application opportunities against alternative
systems like gears, chains that always have a disadvantage in terms of weight, noise, lubrication and
maintenance costs.
The starting point was the long experience cumulated with the existing RPP GOLD line, well known and consolidated
in the marketplace. We improved its even good characteristics, keeping fixed two basic assumptions:
- develop a new belt/system always in rubber to minimise or not change the noise level of the new
drives;
- retain the parabolic design of teeth profile to guarantee an easy up-grade of the existing drives,
in the spirit and concept of interchange ability which identified, along the last years, our market
approach philosophy.
In general every belt component contribute to improve the global mechanical resistance, minimising the risk of belt
break or failure and granting a bigger “specific power” capacity, that means higher basic design performance. However,
the tensile cords of the belt have a significant role to improve the power performance, because they support
tension loads always bigger. Today hi-performance timing belts are built with tensile cords made by steel or aramide
fibres.
Aramide fibres, as well known, have a very poor dimensional stability over the lifetime, thus a timing belt made with
this type of tensile cords will have problems in their length (pitch) stability, which will have a negative impact on lifetime,
because the meshing error that is generated with the pulleys. On the other side, tensile cords made in steel have
an excellent rigidity and dimensional stability over the lifetime, but the belt will have a very high specific weight. Furthermore,
usage of steel cords in association with conventional process for rubber belt assembly, generate so many
extra problems to make this type of construction unaffordable.
The new PLATINUM is a rubber based timing belt, which solve the problems related to steel and aramide cords,
thanks to the development and usage of its innovative “Dual Core” hybrid cord technology. PLATINUM reach the highest
level of performances incorporating this cord in a new rubber matrix and covering the teeth with a special and
unique heavy fabric.
FEATURES
Thanks to the innovative materials used, PLATINUM is a reliable, lower maintenance and economical alternative to
drive systems with chains and gears; it’s particularly recommended for efficient, compact drives with high or pulse
torque loads, offering:
• Increased basic power capacity by up to 40% compared to the current RPP GOLD;
• Use of existing RPP pulleys, maintaining a full functional interchange with other deep pulley profile
systems, like HTD, etc.
• Allows existing drives to be upgraded without the necessity to replace the pulleys, just the belt itself.
• Reduction of noise by reduced belt widths due to the higher performance rating of the system. Under
the same transmission conditions, PLATINUM has the same noise level of RPP GOLD;
• Low noise characteristics compared to drive systems using polyurethane, steel etc. due to the rubber matrix and
its teeth with the parabolic profile shape, recognised as the quietest system on the market
• A wide, continuous range of possible operating temperature, like no other system, which makes PLATINUM the
only solution for extreme working conditions.
