Ball or pin radius Base radius = Ball dia PD (cos PA) angle d = Half of circular pitch Pitch radius = Then we can calculate involute e: inv e = angle a + angle b + angle c – angle d inv e = Thk PD + inv PA + Pin diameter Base diameter – Calculate angle e from inv e Then calculate radius to ball center: Radius to Ball or Pin Center = Base radius cos e

The distance between the pitch line of the rack (a) (see figure N°4) and the rolling line (b) is called corrected profile 5∙6 The corrected profile is positive when the pitch line of the rack is above the cutting pitch circle of the gear In the opposite case there is minus correction

It will become a standard gear calculation if x1 = x2 = 0 If the center distance, ax, is given, x1 and x2 would be obtained from the inverse calculation from item 4 to item 8 of Table 51 These inverse formulas are in Table 52 Pinion cutters are often used in cutting internal gears and external gears

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball

NOTE 1 : The subscripts 1 and 2 of z 1 and z 2 denote pinion and gear All calculated values in Table 41 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

NOTE 1 : The subscripts 1 and 2 of z 1 and z 2 denote pinion and gear All calculated values in Table 41 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 42 Table 42 The Calculations for Number of Teeth

Center Distance C = (2N + n)/6 This formula is to be used as a guide for the MINIMUM center distance only The final selection may vary due to: 1Required clearance dimensions 2Allowing the final chain length to be an even number of pitches NOTE: An odd number of pitches requires an offset link, which should be avoided if possible
