how to measure girth gear root and clearance

Phillips Kiln Services Blog

tire and the gear. Certainly as the tire expands the root clearance will increase. But the gear also expands, which reduces the root clearance. If the tire expands more than the gear then there will be increased root clearance (back lash), conversely if the gear expands more than the gear that would decrease the root clearance.

For larger diameter gears a span measurement or gear tooth calipers can be used. Composite testing can also provide a measurement of gear tooth size. Size measurement is used to provide the correct backlash when the gear is mounted with its mating gear at operating center distance. Measurement of size with micrometer and pins or balls (Figure 1).

XTEK Gear Terminology

Clearance is the distance between the outside diameter of a gear and the root diameter of its mate. This margin compensates for the thermal expansion that occurs during operation, and prevents the top of a gear tooth from interfering with the root of its mating gear tooth. Undercut is the removal of a portion of the tooth profile below the gear's

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 …

Calculation of Gear Dimensions | KHK Gear Manufacturer

NOTE 1 : The subscripts 1 and 2 of z 1 and z 2 denote pinion and gear. All calculated values in Table 4.1 are based upon given module m and number of teeth (z 1 and z 2).If instead, the modulem, center distance a and speed ratio i are given, then the number of teeth, z 1 and z 2, would be calculated using theformulas as shown in Table 4.2.. Table 4.2 The Calculations for Number of Teeth

Girth Gears - More than Just Metal and Teeth

Girth Gear Applications Girth gears fall into two basic categories; flange mounted and tangential spring mounted. Flange-mounted girth gears, the more common of the two, are most frequently utilized in "cold" processing equipment such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries.
