Since the contact conforms
In the case under consideration, S = T and therefore
Equations (2.92) and (2.93) allow eqn (2.89) to be integrated because they
express Q and T maxS respectively in terms of a single variable T. Thus
Before eqn (2.89) can be integrated it is necessary to consider the variation
in Q with N. Since the size of the contact changes with wear, it is possible to
change the number of passes experienced by a pin in one operation
where B = 2nr is the sliding distance during one revolution of the disc.
Because dN — n pdL, where L is the total number of disc revolutions during a
certain period of time, we obtain
Substituting the above expressions into eqn (2.89) gives:
After rearranging, eqn (2.98) becomes
Integration of eqn (2.99) gives
