The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Sometimes, we split teh gear on a plane perpendicular to its axis, and add torque to the system by using the two halves together with springs. Essentially, this system functions like a single gear with expanding teeth. We also taper teeth (in the axial direction), and allow the gear to slide in that same direction to fill the gap more easily.

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.

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.

automation etc. is the backlash. No backlash exists until a gear is meshed with another gear in an assembly. In general, backlash is the lost motion between mating gear teeth (Fig. 2). It may be measured along the line of action or on the pitch cylinder of the gears (transverse backlash) and, in the case of helical gears, normal to the teeth.
