Tip-to-root interference occurs when the gear teeth are too long and interfere with the root of the mating gear due to positive profile shift. Generally, it is recommended that tip-to-root clearance is equal to or greater than $0.25m$. Near peaking spur gear in Gears App

It is also called lash or play. In the context of gears, backlash is clearance between mating components, or the amount of lost motion due to clearance or slackness when movement is reversed and contact is re-established. In a pair of gears, backlash is the amount of clearance between mated gear teeth.

The pinions are new but the girth gear is ... at the tightest spot to the minimum or even a little extra as specified by the gear design. If the root clearance is as much as doubled (at the tightest point) the gear capacity is only de-rated by about 15%. Conversely if the backlash is zero (the root clearance is too tight) there would be tooth ...


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."


Mill Girth Gears, Ring Gears, Bull Gears, Pinions and Shafts. Girth gear drive provide optimum performance as mechanical systems for reducing motor speed to working speed of mill; As an important component in gear drive assembly, these can be offered in multiple segments including 2, 4 or 8 equal sizes; Easy installation and low operational costs; Applications : Girth gears …


Root Clearance Requirement = Thermal Backlash Factor + Tooth Form Root Clearance Factor The root clearance requirement has a tolerance of +0.010 in.,-0.000 in. (+0,25 mm, -0,00 mm). The Thermal Backlash Factor can be determined from the graph shown in Figure 18. The Tooth Form Root Clearance Factor can be obtained from Table 7.


Gears can mesh as shown in the Figure 2.6, however, it is important to consider a proper backlash (play) so that the gears can work smoothly. Backlash is a play between tooth surfaces of paired gears in mesh. Mating gears also have a clearance (play) vertical to tooth depth.


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

Customised solutions In addition to the above capabilities, ... Lift of upper half of girth gear.


This should be avoided on highly loaded gears where the consequently reduced J factor will increase gear tooth stress excessively. b A minimum clearance of 0.157/P may be used for the basic 20-degree and 25-degree pressure angle rack in the case of shallow root sections and use of existing hobs or cutters.
