In general, backlash is the lost motion between mating gear teeth (Fig. 2). It may be measured along the line of action or on the pitch cylinder of the gears (transverse backlash) and, in the case of helical gears, normal to the teeth.

WhatsApp: +86 18203695377What is backlash clearance? Backlash, sometimes called lash or play, is clearance between mating components, sometimes described as the amount of lost motion due to clearance or slackness when movement is reversed and contact is reestablished. For example, in a pair of gears, backlash is the amount of clearance between mated gear teeth.
WhatsApp: +86 18203695377Sometimes, we split teh gear on a plane perpendicular to its axis, and add torque to the system by using the two halves together with springs. Essentially, this system functions like a single gear with expanding teeth. We also taper teeth (in the axial direction), and allow the gear to slide in that same direction to fill the gap more easily.
