ΣΥΝΔΕΣΜΟΙ ΤΥΠΟΥ ΜΑΡΓΑΡΙΤΑΣ
TRASCO flexible coupling is the flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. It has a very compact design and allows safe power transmission by absorbing peak loads and torsional vibrations.
Moreover, the elastic design of the polyurethane gear ring compensates angular and radial misalignments and also absorbs small shaft length variation.
The involute profile of the gear ring teeth prevents high stress concentration on reduced surfaces and the crowned profile avoids the transmission of axial stress.
The high duty factor of TRASCO couplings is due to the fact that the elastic element works under compression and never under flexion.
TRASCO couplings are suitable for working in both horizontal and in vertical positions and easily support any load variation or reversal motion. The two coupling halves are electrically insulated from each other.
TRASCO flexible couplings consist of two precision machined metal hubs and an elastic gear ring (spider) which is resistant to oils, chemical agents, and heat.
Hubs are available in cast iron GG25 or aluminum and, in case of special request, in steel or cast iron GGG40. Each hub is available in version “A” and “B” (in standard or long hub “L” version) which can accommodate different size of bores, leaving unchanged the performance and the technical features.
The gear ring is made of a particular polyurethane resin which shows great advantages in comparison to the standard polyurethanes available on the market. The urethane compound of the polyurethane gear ring offers resistance to aging, hydrolysis, fatigue, and abrasion making it suitable for even the most demanding applications in high humidity conditions. It is self-dampening and shows a great resistance to the main chemical agents, acids, oils, and ozone.
Special types of gear rings are available in order to provide the right solution for each specific application covering a large range of temperatures and resisting specific chemical agents.
