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. This gap means that when a geartrain is reversed the driving gear must be turned a ...

Noun (es) A sudden backward motion. A reaction, objection or outcry, especially of a violent or abrupt nature. The public backlash to the proposal was quick and insistent. (mechanics) 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.

In mechanical engineering, backlash, sometimes called lash, play, or slop, 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."

Expanding upon the previous definition, there are several kinds of backlash: circular backlash j t, normal backlash j n, center backlash j r, and angular backlash Jθ (°), see Figure 14-4. Table 14-1 reveals relationships among circular backlash j t, normal backlash j n and center backlash j r.In this definition, j r is equivalent to change in center distance, Δa, in Section 14.1.

This accumulated backlash can be converted into rotation in degrees: 6.5 Method of Reducing Backlash (Zero Backlash Gears) Low backlash or zero-backlash is the performance required for high-precision gear applications. In order to meet special needs, precision gears are …

The best way to find the tooth height is the drawing of the gear and the pinion. Draw the pinion on the gear drawing as it was in assembly. Add clearance on the root of the tooth. The clearance is often equals 0.25 (or 2.0 or 1.8) * (normal module). Get Price.

normal backlash. The blade tips extend about the tooth deden-dum (hF)—beyond the generating plane (blade dedendum). The blade contours in Figure 3 are therefore not exactly con-gruent to each other, but by the backlash values different on the flanks and by the clearance values different at the roots (tips).

Answer (1 of 13): In general, backlash in gears is play between mating teeth. For purposes of measurement and calculation, backlash is defined as the amount by which a tooth space exceeds the thickness of an engaging tooth. It does not include the effect of …

Backlash is a play between tooth surfaces of paired gears in mesh. Mating gears also have a clearance (play) vertical to tooth depth. This is called Tip and Root Clearance (c), the distance between tooth root and the tooth tip of mating gears. Tip and Root Clearance (c)

Actual Root Diameter and. Cleaeance The European method doesn't. calculate the actual root diameter of gear which are thinned. for backlash by feeding the cutler to greater depth. When the actual root diameters are cal-culated, the addendum diameter required for standard clearance can be calculated more ac-curately from Eq..11.
