The resilient type of coupling has many designs but essentially has
torsional response to application or variation of the transmitted load.
For the all-metal types, the resilient element may be in the form of
laminated spring packs or a cylindrical grid member, connecting the driver
and driven hubs. Resilience damps shock loads and also provides means of
keeping gear teeth in contact, compensating for small errors in gear
cutting. Other types use rubber or rubberlike material that may be in the
form of a spider, segmental blocks, a number of balls, or a molded disk
with metal inserts, providing the connection between the driver and driven
hubs. Pit and Quarry
