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.
Ball Mill Sole Plate. This crown should be between .002″ and . 003″, per foot of length of sole plate. For example, if the sole plate is about 8′ long, the crown should be between .016″ and .024″.

There are three ways to align the pinion skew to the girth gear; 1) Using the pitch lines 2) Setting root clearance 3) Setting backlash (only applicable to a new gear and pinion). Measuring the root clearance is best done using Babbitt or lead slugs. Use % 1" diameter Babbitt slugs about 1 to 2" in length.

Anonymous Poster #1. # 4. Re: Ball Mill Girth Gear and Pinion Alignment. 08/27/2011 2:07 AM. pinion alighnment is done by coating the pinion with a lead based grease. after rotating the drum, the grease marks will show the contact area. the pinion should contact the girth "ring" near the center of the gears.
a specific example, a 6,250kW ball mill gear at output speed has a required rim thickness value of 210mm ( in) in a tee configuration whereas the box Y gear has 165mm ( in). This reduces the overall weight of the gear to 61,600 kg (135,700 lbs.) in a box Y configuration but 67,500 kg (148,700 lbs.) as a tee configuration.
