The gear box is a setup intended for making the power transmission from the electric motor to the ball mill. During this stage the gear box plays a crucial role in terms of controlling speed and torque. The gear box is a collection of shafts, bearings, casing and gears in a systematic form to obtain the desired output.

List of gear nomenclature Wikipedia

A gear center is the center of the pitch circle. Gear range. The gear range is difference between the highest and lowest gear ratios and may be expressed as a percentage (, 500%) or as a ratio (, 5:1). Heel Heel and toe. The heel of a tooth on a bevel gear or pinion is the portion of the tooth surface near its outer end.

The traditional methods of backlash measurement include lead wire method and gap measurement method, 13 The backlash can be obtained by measuring the thickness of the thinnest part after the gear extrudes the lead wire or by measuring the data with a feeler gauge. The traditional method can get better precision in static measurement, and can be used as a reference for single backlash measurement.

[Solved] Backlash in gears is

It is the radial distance between pitch circle and the addendum circle. The addendum is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard pitch circle or pitch line. In the gear drive, Standard Addendum = 1 module. But we know that, addendum (a) a = 1 D P = C P π = C P.

Gearbox Tooth Cut Fault Diagnostics Using Acoustic Emission and ... MDPI

In addition, if a tooth was cut deeper than the addendum circle, the tooth would lose the initial contact point during gear meshing and lead to more backlash. For the most common involute gears, the ratio between addendum and dedendum is 1: Therefore, a 50% depth tooth cut would introduce larger backlash than healthy gear and a 25% tooth cut.
