YELLOW SPIDER EG48060

Elastomeric shaft coupling with accuracy and increased resistance to torsion. The elastomeric in yellow spider shape EG48060 of 92 hardness is the elastic coupling for GTE48060 GTI48060 SGMA48 and SGMB60 type couplings. The design of flexible couplings is characterized by two cast iron hubs having each stubby protrusions around their perimeters pointing towards the opposing hub. The two hubs mesh loosely together and the gaps between them are filled with blocks of elastomeric material molded into an asterisk-shaped element called “spider”. Couplings are elements connecting two rotating shafts and beyond transmitting power from one shaft to the other they perform the following functions: Ensure a torque transmission free from shocks by damping any torsional vibrations either due to load or self-induced Minimize torque shocks and peaks at a starting phase Compensate for slight angular and parallel shaft misalignments. General features. In flexible couplings the spider is the element determinant for the torque rating of every coupling. Its constructive material can make a significant difference in the coupling response to contrast factors as vibration temperature chemicals misalignment high RPM.The great advantage of flexible couplings lies in their “fail-safe” design as the coupling is not necessarily destroyed or rendered inoperable if the spider breaks away during operation. The system will continue to function in safety conditions preventing critical system downtime until the spider can be replaced at a more convenient moment. Applications. Flexible couplings are generally recommended for continuous-duty electric motor-driven machinery pumps gearboxes etc.
