Abstract The calculation scheme of the reel of the combine harvester “Lida-1300” is given. The operating time of the bearing of reel support for service life of the combine, the frictional loads of the bearing and the bending stresses of the shaft are determined. Loading blocks are formed with increasing, decreasing and arbitrarily changing load. The influence of values of the softening parameters α and hardening parameters β, the duration of the loading stage on the calculated wear value and durability is analyzed. It has been established that for unchanged or insignificantly changing values of the parameters α and β, the calculated wear values coincide at the end of the loading block, regardless of the order of loads (increasing, decreasing or arbitrarily changing) and the duration of the loading stage. While with a significant difference between the parameters α and β, the coincidence of the calculated wear values at the end of the loading block appears only for a short duration of the loading stage (approximately two orders of magnitude less than the estimated lifetime). A comparison of the calculated wear kinetic curves is made under regular and irregular loading with an operating time of 2.0·107 cycles.
