Backlash (engineering) - WikipediaStandard practice is to make allowance for half the backlash in the tooth thickness of each gear. However, if the pinion (the smaller of the two gears) is significantly smaller than the gear it is meshing with then it is common practice to account for all of the backlash in the larger gear. This maintains as much strength as.ballmill pinion back lash setting,SAG mill pinion - gear alignment - Reliability Magazine® Message .The pinon was turned about four months ago and the back side of the teeth are worn unevenly so probaqbly won't be able to get a reliable back lash .
