ring motor drive a grinding mill without contact between rotating and fixed parts. this concept avoids girth gear and pinions, which are used for conventional mill drives. the stator of the ring motor is wrapped around the mill as a ring. due to the large size, the stator is fabricated and transported in segments. At site, the stator segments

articles are sorted by relevance. sort by date.. gear backlash analysis of unloaded gear pairs in transmissions best practice in gear design is to limit the amount of backlash to a minimum value needed to accommodate manufacturing tolerances, misalignments, and deflections, in order to prevent the non-driving side of the teeth to make contact and rattle.
gears can mesh as shown in the figure 2.6, however, it is important to consider a proper backlash so that the gears can work smoothly. backlash is a play between tooth surfaces of paired gears in mesh. mating gears also have a clearance vertical to tooth depth.
In general, backlash in gears is play between mating teeth. for purposes of measurement and calculation, backlash is defined as the amount by which a tooth space exceeds the thickness of an engaging tooth. It does not include the effect of center-
