Conformal Efficiency Factors of Friction Pairs in Construction Machinery

Formulae for the efficiency factor of moving friction pairs construction equipment are investigated in terms their mutual adaptation (conformism) during and wear. As a basis, average coefficients sliding dimensions reference line curves, half-sums products worn surfaces microrelief mating parts taken. Coefficients lines were determined from partial values microwear micromaterial normalized system relative convergences. Calculated conformal factors compared with obtained tested dependence, as well wedge operator dry mode. The research was carried out on example model hinges hydraulic excavator attachments.
