The distance between the outside circle of a gear and the root circle of its mating gear (the gap) is called the root clearance. This distance (the gap) is also called the root clearance, top clearance, bottom clearance or simply the clearance.

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.

Before the drive train can engage the load and transmit torque, the gears must close this gap. If these gaps become too large, however, the gearbox introduces the kind of lost motion we've been discussing. In the case of couplings, compliance can appear as backlash and can introduce a wind up before the load moves.

Dialing It In. Once fully seated, install and tighten down the carrier pads. Always install and tighten the right side first. With the carrier assembly installed, attach your dial indicator with the plunger at a 90degree angle from the face of the ring gear teeth. Gently rock the carrier back and forth to measure your backlash.

The main gear is cut from a special gear steel casting and is made split and reversible. The pinion, usually integral with the pinion shaft, is cut from an alloy steel forging and heat treated prior to cutting the teeth. The pinion shaft is double ended so it is also reversible.

The Gear box backlash is the clearance or gap between the two mating gear tooth. The backlash can be measured with dial gauge, feeler gauge or lead wire. The Dial Gauge pointer is kept at Driven gear face and the drive gear is locked. Then the driven gear is moved which shows the backlash valve in the dial gauge.
