Increased Wear Resistance of Articulated Spherical Bearings Due to Nitriding

Бесплатный доступ

This article describes a technique for determining the wear intensity of the spheres of articulated spherical bearings. The results of determining the coeffi cient of wear intensity in a friction pair of steel SHX-15 and EI347 with various types of thermochemical treatment are presented. The experimental values of the coeffi cient of wear intensity were approximated in the form of a powerlaw analytical relationship with respect to contact stresses. The approximation error did not exceed 20%. The obtained dependences will allow us to determine the wear values of the material, taking into account changes in the maximum contact stresses. The use of nitriding in the sphere of articulated bearings increases their durability.
