The distance through which one part of connected machinery, as a wheel, piston, or screw, can be moved without moving the connected parts, resulting from looseness in fitting or from wear
For a motion system the backlash is defined as the lost motion after reversing direction Reasons can be play in screw/nut fittings, gearheads, bearings, insufficient axial preloads Backlash is fairly repeatable and can be compensated for
Term describing the amount of play between gears, or gear mesh If too loose, the gear can slip, or strip the teeth Too tight, and excessive wear is caused
Mechanical dead band caused by clearance between drive train components resulting in lost motion which may occur upon reversing direction It may be caused by inaccuracy or improper preloading of a nut of axial bearing on a linear ball screw drive or gear teeth meshed against a worm gear drive in a rotary stage
Describes the play in the meshing of two gears Too much backlash and the gears could slip or break the teeth, too little backlash could cause excess wear and tear The common rule is the thickness of two sheets of paper for the right am ount of backlash
Backlash is a negative response to an action When someone or a group is forced to do something against their will they will often resist or try to get back at the person or group who forced them in the first place This can result in a reversal of an apparently resolved situation, and may even escalate the conflict further
Rotational movement of the output shaft clockwise and counter clockwise, while holding the input shaft stationary Usually expressed in thousandths of an inch and measured at a specific radius at the output shaft
The distance through which one part of connected machinery, as a wheel, piston, or screw, can be moved without moving the connected parts, resulting from looseness in fitting or from wear; also, the jarring or reflex motion caused in badly fitting machinery by irregularities in velocity or a reverse of motion
A backlash against a tendency or recent development in society or politics, is a sudden, strong reaction against it. the male backlash against feminism. a right-wing backlash. = reaction. a strong negative reaction by a number of people against recent events, especially against political or social developments backlash against
