Theoretical and Experimental Substantiation of Angle Orientation of Rolling Bushings of Roller and Bushing Chains

Shape accuracy (deviations from the rounding) of inner cylindrical surface (ICS) of built-up bushings of transmission roller and bushing chains (TRBC) and its influence on wear-resistance of their joints and increase of internal t_in and external t_ex contact steps is considered. Deviations from the rounding of inner cylinder surfaces of built-up bushing of transmission roller and bushing chains along ICS perimeter as well as built-up joints and diametrically opposite areas are obtained as the result of out-of-roundness profiles statistic processing. It is determined that minimum deviations from the rounding of ICS of built-up bushings take place in the area which are defined by central angle equal π/2 and is situated diametrical opposite to bushing butt joint.
