Spur Gears

WigginsSpurGearsSpur gears have teeth with leading edges cut parallel to the axis of rotation. These straight-cut gears are the simplest type of gear and work properly only when meshed with parallel axles. The hand-driven gear that meshes with the fork gear in most turntables, returns and arcs is a good example. The rate of rotation for the smaller fork gear is greater than the larger hand-driven gear that turns it, so the apple rotates faster than the hand-driven gear. Divide the number of teeth on the hand-driven gear by the number of teeth on the fork gear and you will know how many times the apple will rotate for every complete turn of the crank. Multiple spur gears were employed by many designers of parers and often proved a very aesthetic appearance (above). The hand-driven and fork gear of the Parker is pictured below.
