Shaft to shaft clutch coupling: 21st May, 2009

Most centrifugal clutch applications involve the clutch being mounted on a shaft with the output power coming via belt or chain. (see photo) By these methods parallel shafts are connected without needing a flexible coupling. Belts or chains accommodating small misalignments.

However in other cases it is necessary to connect two shafts coaxially or inline. Unless angular and radial errors can be eliminated altogether, a flexible coupling must be built in which will also absorb shock loads and torsional vibrations associated with in particular diesel engines.

The photo shows a centrifugal clutch with a 'doughnut' type rubber flexible coupling. The output hub is pilot bored prior to finish boring and keywaying.

Combining a standard clutch with a standard coupling has the effect of reducing cost and delivery times on what would otherwise become a 'special' configuration.
