Introduction ® TRASCO Jaw Couplings 1 www.jbj.co.uk/couplings.html #DriveLineHarmony Description ® The TRASCO flexible coupling is the flexible constant velocity 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. The elastic design of the polyurethane coupling element 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 these couplings is due to the fact that the elastomeric element works under compression and never under tension. TRASCO® couplings are suitable for working in both horizontal and in vertical positions and easily support any load variation or reverse motion. The two coupling halves are electrically insulated from each other. ATEX Directive 2014/34/EU It is possible to ask for specific certification for use in hazardous area according to ATEX Directive 2014/34/EU. TRASCO® couplings are available with specific mounting/operating instruction manual and conformity. For information, please contact the jbj Techniques Ltd. technical office, telephone: +44 (0)1737 767493 or email: info@jbj.co.uk 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 ductile 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. “A” Type “AR” Spider “B” Type “BL” Type “AL” Type
Coupling Element & Sizing ® TRASCO Jaw Couplings 2 www.jbj.co.uk/couplings.html #DriveLineHarmony Spider Elements The coupling element 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 these polyurethane coupling element 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-damping 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.

Couplings must be selected to ensure that the maximum admissible torque is never exceeded during operation. It is necessary to have correct sizing, so that all conditions hereunder are respected. 1) Verify 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. T >T •S (Nm) KN N q Note that T = 9550 P (Nm) N N n Where P is the motor nominal power in kW. N 2) Verify the maximum torque. The max torque of the coupling must be greater than or equal to the starting torque Ts multiplied by the safety factors S , S , S where S is the higher value θ Z u u between driver and driven units. T > T • S • S • Su (Nm) Kmax S q Z 3) Verify torque with reversal. In case of torque with reversals it must be verified that: T > T • S (Nm) KW W q where T = torque with reversal, which the coupling can bear, and T = torque variation of the drive. KW W Shore Hardness
Coupling Element & Sizing ® TRASCO Jaw Couplings 3 www.jbj.co.uk/couplings.html #DriveLineHarmony In case of drives with high torsional vibrations (e.g. piston compressors, combustion engine) it is recommended to undertake torsional vibration calculations in order to guarantee the correct functioning of the coupling.

It is important to verify the maximum torque in the drive is lower than the torque which the hub shaft connection can bear. In case of keyway connection, it is important to verify the tensile strength of the hub material with the load which the keyway seat must transmit.

Coupling Element & Sizing ® TRASCO Jaw Couplings 4 www.jbj.co.uk/couplings.html #DriveLineHarmony The sum of the admissible value (A) and the respective values shown in the table must be less than or equal to 1. Dynamic torsional rigidity C is the first derivate of the nominal torque of half coupling in respect to the torsion angle. j is the torsion angle of half Tdin coupling in respect to the second half. As a general rule, C is greater than CT and depends on the stress acting on the coupling. Tdin Misalignment TKN j dj dTKN The values shown in the table for radial and angular misalignment, must be corrected in case they are simultaneously acting on the coupling.
