The clearances including tooth backlash and bearing clearance will contribute to the gear vibration and noise problems. The tooth backlash may be introduced in the design stage to provide lubrication and eliminate interference, or caused by the manufacturing errors and wear [23], [24] .

Backlash is the play, or clearance, between gear teeth in gearheads. In other words, backlash is the movement in the gear shaft while the motor shaft is fixed. In mathematical terms, it is the width of the space between meshing gears minus the width of one gear tooth.
