grooved pulley

There was a grooved pulley used for the paying-out machinery with a spindle wheel, which might suit me.

In operation, the band passes over two grooved pulleys rotated by a wind-up clockwork motor.

In the earliest applications power was transmitted between pulleys using loops of rope on grooved pulleys.

In a "traction" lift, cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry.

Oscillating brass cylinder and piston, spring loaded safety valve, dome whistle, flywheel of 7 cms diameter with grooved pulley.

The cables rode upon hundreds of small grooved pulleys, each with a small cotter pin installed to insure the cable didn't jump out of the grooves.

Its ends were connected to a greasy inch-and-a-half-diameter cable secured to large grooved pulley wheels, which were jerked in rotation and exploded in a cloud of oil mist as the massive arresting mechanism stopped the heavy craft, traveling at 120 knots, in under two seconds.

Front-loading washers are mechanically simple compared to top-loaders, with the main motor (a universal motor or variable-frequency drive motor) normally being connected to the drum via a grooved pulley belt and large pulley wheel, without the need for a gearbox, clutch or crank.
