What's the difference between capstan and spindle?

Capstan


Definition:

  • (n.) A vertical cleated drum or cylinder, revolving on an upright spindle, and surmounted by a drumhead with sockets for bars or levers. It is much used, especially on shipboard, for moving or raising heavy weights or exerting great power by traction upon a rope or cable, passing around the drum. It is operated either by steam power or by a number of men walking around the capstan, each pushing on the end of a lever fixed in its socket.

Example Sentences:

  • (1) Rotation of a permanent pacemaker can result in a capstan effect, and the lead is drawn out of the right ventricle.
  • (2) The same holds for pulley- and capstan-form toric surfaces.

Spindle


Definition:

  • (n.) The long, round, slender rod or pin in spinning wheels by which the thread is twisted, and on which, when twisted, it is wound; also, the pin on which the bobbin is held in a spinning machine, or in the shuttle of a loom.
  • (n.) A slender rod or pin on which anything turns; an axis; as, the spindle of a vane.
  • (n.) The shaft, mandrel, or arbor, in a machine tool, as a lathe or drilling machine, etc., which causes the work to revolve, or carries a tool or center, etc.
