Product Name:
Coupling Castings in China Foundry, Shaft Coupling Casting
Parts, Ductile Iron Coupler, Cast Iron Machine Parts
Application on:
Shaft coupling, in machinery, a device for providing a
connection, readily broken and restored, between two adjacent
rotating shafts. A coupling may provide either a rigid or a
flexible connection; the flexibility may permit misalignment of
the connected shafts or provide a torsionally flexible
(yielding) connection, mitigating effects of shock.
A common type of rigid coupling consists of two mating radial
flanges (disks) that are attached by key-driven hubs to the ends
of the shafts and bolted together through the flanges. Alignment
of the shafts is usually achieved by means of a short
cylindrical projection (rabbet joint) on the face of one flange
that fits snugly into a circular recess on the face of the other
flange.
The chain coupling consists of two hardened-steel sprockets, one
on each shaft, with a nylon or metal roller chain wrapped around
the closely aligned sprockets and connected at the ends.
Clearances between the sprocket teeth and the chain allow for a
small amount of shaft misalignment.
For connecting shafts whose axes intersect but are inclined to
one another at a larger angle than a flexible coupling can
accommodate, universal joints are used. The most common of these
is the Hooke, or Cardan, joint, which consists of two yokes
attached to the shaft ends and a cross-shaped connecting member.
