Available as spur, worm, and bevel styles, anti-backlash gears are the most widely used and most inexpensive method of eliminating the inaccuracies encountered in low torque gear trains, where precise positioning is essential to an application. Anti-backlash gears have minimum or no backlash (play). Anti-backlash capabilities can be applied to many types of gears, and is most commonly seen in spur gears, bevel gears, miter gears, and worm gears. Sometimes backlash is a favorable and necessary part of the way gears work, but in some situations it is desirable to have little or no backlash.
The split gear design incorporates springs, which force the floating gear in a direction opposite the rotation of the fixed gear, effectively enlarging the tooth width and overcoming the space, or backlash, between the teeth of the gear with which it is meshed. Two types of design are available, one utilizing scissor springs, and the second for larger diameter gears, utilizing extension springs. Anti-backlash gears are stocked in aluminum or stainless steel but can be supplied in other materials or to other configurations on request. Learn more about our custom anti-backlash gears.
