Fatigue: This is a slow and progressive failure and is a result of cyclic loading. This type of failure, mostly occurs in three stages (i) crack initiation (ii) crack propagation and (iii) fracture respectively. Fig. 3(a) describes the fatigue on a gear tooth surface and this type of failure occurs in the tooth root fillet (Fig. 3(b)).

The segmental gear, which receives/communicates reciprocating motion from/to a cogwheel, consisting of a sector of a circular gear/ring having cogs on the periphery, was invented by Arab engineer Al-Jazari in 1206. The worm gear was invented in the Indian subcontinent, for use in roller cotton gins, some time during the 13th–14th centuries.

What is the backlash in gears? How is it advantageous or ...

Moreover, the width of a tooth must be less than the width of a space, to permit easy meshing. The necessary clearance results in backlash between the gears. This means that if the driver is reversed, it rotates a short ways until it again contacts a tooth.
