Boson hi, Torque type resilient couplings are in use in every variety of industrial applications over a long-standing experience of success. Such a resilient coupling comprises mainly two hubs, Grid spring as well as enclosures to protect the spring. The mesh spring element is so designed that it provides required resiliency for variable flexibility of a joining piece and considerable damping properties making the coupling very suitable for drives involving high shock loads to the extent of 80%. Misalignment that inevitably occurs between which are, Rotating shafts indendently supported, Is also properly managed by the spring element within allowable limits. Dimensions given in the tables are rough estimates and pertain to standard coupling of but tailor, Made couplings, Boson range with hubs of longer or shorter lengths, Seals & grub screws is further able to function as supplied based on demands of individual customer. Following service information must feature enquiries, 1. H. P. & Rotations per minute of the drive 2. Types of driving & driven machines 3. Nominal diameters and lengths of shaft extensions of both the machines 4. Dimensional details of finished bores & keyways, If required 5. Any other details relevant to the working conditions of the drive.
