    Types of BacklashesBacklash RelationshipsTooth Thickness and BacklashGear Train and BacklashMethod of Reducing Backlash(1) Circumferential Backlash ( j t ) Circumferential Backlash is the length of arc on the pitch circle. The length is the distance the gear is rotated until the meshed tooth flank makes contacts while the other mating gear is held stationary. (2) Normal Backlash ( j n ) The minimum distance between each meshed tooth flank in a pair of gears, when it is set so the tooth surfaces are in contact. (3) Angular Backlash ( j θ) The maximum angle that allows the gear to move when the 
  • Backlash (engineering) Wikipedia

    In mechanical engineering, backlash, sometimes called lash or play, is a clearance or lost motion in a mechanism caused by gaps between the parts.It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence".

  • Surface grinder: vertical backlash a problem?

    Mar 15, 2017· Last summer I got a surface grinder, a 6x18" Jones & Shipman 540 APR. The regulars here helped me to get it fixed up and working. I noticed something a few days ago, and it's gotten me wondering. When I have worked with it before in the past, I'm pretty sure that the grinder's vertical axis had zero backlash.

  • Eliminate Backlash From Machining Centers : Modern Machine

    Jun 01, 2000· The best way to correct axes (at least with box way construction) is to adjust the machine's gibs to eliminate the backlash all together. When you must machine holes in precise X, Y locations (when finish boring, for example), backlash can cause positioning errors in hole locations if the motions required to machine the holes cause a reversal

  • Machine backlash High Power Media

    One of the biggest issues with any machine tool, camshaft grinders included, is that of axis backlash. Defined as the loss of motion when the machine's axis, either rotational or linear, reverses, it can have a major influence on the precision of the component being made. With camshaft lobes needing to be ground to accuracies of +/- 6 microns or better, the backlash in the machine

  • What is backlash? Detail of CNC machine tool backlash in

    Backlash in the X or Y axis of machining centers is most obvious when milling full circles. If any backlash exists, there will be a nasty witness mark on each quadrant line (X+, X-, Y+ and/or Y- side of the circle). As you probably know, backlash is caused by normal usage, and checking for backlash (easily done with a dial indicator) should be
