1) Description of Spur Gear
Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth
projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight
and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is
usually not triangular. Instead of being straight (as in a triangle) the sides of the cross section have a curved
form (usually involute and less commonly cycloidal) to achieve a constant drive ratio. Spur gears mesh together
correctly only if fitted to parallel shafts.
2) Pressure angle of Spur Gear
Spur gear can be classified into two pressure agnles.
20° being the current industry standard and 14½° being the former equipments.
