ANSI/AGMA publishes detailed standards for gear design and drawings.

Working drawings for bevel gears give both the dimensions of the gear blank and the data necessary for cutting the teeth.

Cams are used to produce regular repeating motions.

Proportions and shapes of gear teeth are not standardized.

A worm is a screw with a thread shaped like a rack tooth.

The motion of the follower as it rises or falls depends on the shape of the curves in the displacement diagram.

In working drawings for worm gears, gear teeth are omitted and the gear blank is represented conventionally.

Gears are used to transmit power and rotating or reciprocating motion from one machine part to another.

Teeth are spaced by laying out equal angles.

In working drawings with teeth cut to a standard shape, individual teeth typically are not shown.

On detail drawings, the worm and gear are usually drawn in the same detail drawing.

Bevel gear teeth have the same involute shape as teeth on spur gears but are tapered toward the cone apex.

Worm wheels are similar to helical gears cut to conform to the shape of the worm.

When the follower movement is in a plane parallel to the cam shaft, an irregular cam must be employed.

When laying out a gear, the number of spaces should be twice the number of teeth.

Gear teeth formed on a flat surface are called this:

Spur gear design normally begins with selecting this:

The most common geometric form used in gears today is this:

This is a curve showing the displacement of the follower as ordinates on a base line that represents one revolution of the cam:

These gears transmit power between shafts whose axes intersect at any angle:
