In mechanical engineering, backlash, sometimes called lash or play, is a clearance or lost motion in a mechanism caused by gaps between the parts.It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence".
Gears that are smaller than 32 teeth for a 14.5° Pressure Angle, or 18 teeth for a 20° Pressure Angle, have a Root Circle smaller than the Base Circle, resulting in the teeth being undercut. Undercutting is avoided by the use of Profile Shift, the shifting the the Addendum and Dedendum outward without altering the location of the base circle.

Meshing – correct alignment of working teeth of pinion (or pinions) and girth gear. The root clearance and backlash parameter should be measured and recorded. Teeth contact – can be observed by analyzing the contact pattern; Teeth line separation – checking whether overlapping exist. Axial run-out measurement – should not exceed design ...
Girth gears are high precision components that are preferred over the gear less drives due to their lower initial cost, simple installment procedure and lower operational and maintenance costs. These are used in industries like steel, sugar, paper and pulp. We manufacture and export high quality girth gears.
It is also called lash or play. In the context of gears, backlash is clearance between mating components, or the amount of lost motion due to clearance or slackness when movement is reversed and contact is re-established. In a pair of gears, backlash is the amount of clearance between mated gear teeth.

axial run-outs, of the backlash, the root clearance and of the free play. Note: When a gear set must be turned because of wear, it is no longer possible to align the gears by means of the backlash. The drive must be set up by means of the root clearance.A suitable guide value for the tooth tip play is 0.25 to 0.3 times the module.

Spur Gear Backlash Review - Spur gear backlash is the amount of tooth space between mating gears at the pitch circle diameter. Backlash may be measured or specified in the transverse, normal, or axial planes, and in the direction of the pit circles or on the line-of-action.
SPUR GEARS BACKLASH Stock spur gears are cut to operate at standard center dis-tances. The standard center distance being defined by: Standard Center Distance = Pinion PD + Gear PD 2 When mounted at this center distance, stock spur gears will have the following average backlash: An increase or decrease in center distance will cause an increase ...
Backlash, a clearance between mating gear teeth, is built into speed reducers to let the gears mesh without binding and to provide space for a film of lubricating oil between the teeth. This ...

Low and high – to low or too high value of root clearance. Short – the reason of this pattern very often is uneven and hard part of pinion teeth surface. Bridge – the root clearance can be too low and alignment of pinion is not correct. Wedge – main reason of this wear pattern is angular non-alignment between pinion and girth gear.
