Rotoflex tyre type coupling comprises a rubber tyre of high quality. This coupling has some constructional features which include: this rubber tyre connects two metal hubs--one on the driving shaft and the other on the driven shaft. The tyre with reinforcement, specially designed and manufactured, provides reasonable resiliency to the tyre couplings feature that makes a tyre coupling capable of absorbing shock load, parallel misalignment up to 4 mm, end float up to 5 mm or combination of all misaligmnents depending upon the size of the coupling. Following are some technical features of this coupling which include: Design and construction of tyrt, coupling is such that its mounting on and dismantling from shafts can be easily accomplished. Inspection of components can be carried out without dismantling of coupling. Without disturbing the alignment of the installation, this tyre element can be easily replaced. No lubrication is needed.
