TRCO couplings Description TRCO flexible coupling is the flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class.

oreover, the elastic design of the polyurethane gear ring compensates for angular and radial misalignments and also absorbs small shaft length variation.

The high duty factor of TRCO couplings is due to the fact that the elastic element works under compression and never under flexion.

The two coupling halves are electrically insulated from each other.

1 TRCO couplings Description TRCO flexible coupling is the flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. t has a very compact design and allows safe power transmission by absorbing peak loads and torsional vibrations. oreover, the elastic design of the polyurethane gear ring compensates for angular and radial misalignments and also absorbs small shaft length variation. The involute profile of the gear ring teeth prevents high stress concentrations on reduced surfaces and the crowned profile and avoids the transmission of axial stress. The high duty factor of TRCO couplings is due to the fact that the elastic element works under compression and never under flexion. TRCO 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. TRCO xecution xecution R pider xecution xecution TX Directive 2014/34/U t is possible to ask for specific certification for use in hazardous area according to TX Directive 2014/34/U. TRCO couplings are available with specific mounting/operating instruction manual and conformity. For information, please contact our technical office. TRCO flexible couplings consist of two precision machined metal hubs and an elastic gear ring (spider) which is resistant to oils, chemical agents, and heat. ubs are available in cast iron 25 or aluminum and, in case of special request, in steel or cast iron 40. ach hub is available in version and (in standard or long hub version) which can accommodate different size of bores, leaving unchanged the performance and the technical features. 3

2 pider 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 our polyurethane gear ring offers resistance to aging, hydrolysis, fatigue, and abrasion making it suitable for even the most demanding applications in high humidity conditions. t is self-dampening and shows a great resistance to the main chemical agents, acids, oils, and ozone. pecial 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.

3 TRCO coupling sizing as per D 740/2 TRCO coupling sizing is made according to D 740/2. Couplings must be selected to ensure that the maximum admissible torque is never exceeded during operation. t is necessary to have correct sizing, so that all conditions hereunder are respected. 1) erify the nominal torque The nominal torque of the coupling must be greater than or equal to the nominal torque of the drive multiplied by the temperature safety factor.

10 RC series for use with T-OCK elements type 8 This execution has been introduced to incorporate advantages offered by the T-OCK locking elements in the shaft-hub connection. The system allows for a quick, safe and backlash free mounting without the use of keyway and eliminating the need for lock washers, spacers and stop rings. any different solutions may be created to solve all kinds of application needs.
