Construction and Design of Spur Gears

Spur gears, also known as straight-cut gears, are one of the simplest types of gears. They are characterized by teeth that project radially from a cylinder or disk. Despite their seemingly straightforward structure, the teeth of spur gears are not straight-sided. They are usually designed with a specific shape – primarily involute but occasionally cycloidal – to maintain a consistent drive ratio.

The edge of each tooth of a spur gear is straight and aligned parallel to the axis of rotation. This design ensures that the gears mesh together perfectly only when fitted to parallel shafts. Unlike other types of gears, spur gears don’t generate axial drive from the tooth loads. These gears perform exceptionally well at moderate speeds, although they can be a bit noisy at high speeds.

The Involute Tooth Shape

All WLY spur gears feature an involute tooth shape. This means that the gears employ a segment of the involute curve as their tooth form. The involute shape is widely used in gear tooth design for several reasons. It can absorb small center distance errors, simplify manufacturing with easily produced formation tools, and provide thicker tooth roots for increased strength. The tooth shape is often specified in the drawing of a шпорная перадача according to the height of the teeth. In addition to standard full depth teeth, extended addendum and stub tooth profiles are also available.

Профіль Shifted Gears

Profile shifted gears, though not exclusive to spur gears, are utilized when it’s necessary to adjust the center distance slightly or to strengthen the gear teeth. They are created by modifying the distance between the gear cutting tool, known as the hobbing tool, and the gear during the production phase. A positive shift increases the bending strength of the gear, while a negative shift slightly reduces the center distance. Backlash, or the play between the teeth when two gears are meshed, is essential for the smooth rotation of gears. Excessive backlash can cause increased vibration and noise, while insufficient backlash can result in tooth failure due to lack of lubrication.
