Girth gears fall into two basic categories; flange mounted and tangential spring mounted. Flange-mounted girth gears, the more common of the two, are most frequently utilized in "cold" processing equipment such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries. By current stan-dards, girth ...

The TOE of the gear is the portion of the tooth surface at the end towards the center. The HEEL of the gear tooth is the portion of the tooth surface at the outer-end. The TOP LAND of a gear tooth is the surface of the top of the tooth. Every gear has a characteristic pattern. There are two types of gears which are determined by the machining ...

If you hear clunk, clunk - stop and change how you are doing things. Short drill bits (for screw machines) are a big help with limited Z motion on this mill. To get to the spindle bearings, you do not need to remove the top pulley. Just remove the handle and fine feed housing to access the pinion gear.

The mill drive system consists of the main mill motor, the main reduction gear box, mill pinion and girth gear. The mill is also equipped with a barring drive which is either connected to the main drive reduction unit or alternatively mounted at the back of the main motor. Refer to Figure 2 for a schematic of the mill .

However, loads in a mill are not clearly and precisely defined. Of course, there are rules to calculate the maximum stress in rolls caused by design limits for maximum separation force, torque, Hertzian pressure etc, but these criteria are valid only under so called "normal rolling conditions" and even these change continuously with progressive

– A 2:1 back gear is essential for lower horsepower motors just to survive with steel. 5 HP with a 2:1 back gear gets you all the way down to 100 rpm. – 5:1 back gear is too wide a spread with a 2 HP motor. You'd have a dead zone from 800 – 1500 rpm. – 3:1 back gear 2HP looks about right to me.

Two general classifications of gearing are used for ball Mill drives. These are the spur gear and the helical gear. Helical gearing may be either of the single helical or double helical (Herringbone) design. SPUR GEARS These are generally furnished on the smaller diameter mills using V-belt drives or reducer drives. Spur gears and pinions are cut with teeth of the full depth involute tooth ...

May 24, 2004 · If this lower torque is sufficient to run the rubber mill, the proposed system of 800/40 RPM gear box will work with a lower load on the motor. But if the lower gear box torque (at 800 RPM) is insufficient (more likely given the rubber load on the mill), then to increase the torque, the motor amp-turns (or rather the motor amps) has to increase.

The combined motor to gearbox and gearbox to mill drive pinion misalignments resulted in a loss of end float within the gearbox, trapping the intermediate shaft gear. The 10.3-degree C temperature difference across the mill drive pinion gear was also considered excessive and indicative of severe pinion to girth gear misalignment.
