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 Vbelt drives or reducer drives. Spur gears and pinions are cut with teeth of the full depth involute tooth
WhatsAppعرض المزيدParallelSha˝ Gears Spur gears are by far the most common type of parallelshaft gear. They are simple to design, highly e˝cient, and relatively forgiving of mounting errors. Spur gears can handle high horsepower and shock loads but are not the most compact way to transmit power due to the relatively low contact ratio that can be obtained.

WhatsAppعرض المزيد· Both gears and pinions on twin ball mills failed almost simultaneously. Our 2001 paper showed that the location of the failures is explained by the shape of the girth gear blanks. Fresko et. al. [2] shows that Tgears are in fact better than Ygears in terms of load distribution and that the diameter of the pinion in a gear set can result in excessively high loads at the ends of the pinions.
