FIELD: mechanical engineering.
SUBSTANCE: invention relates to repair of rotary machines and it can be used in pumps, compressors and equipment in which sliding bearings are used. Proposed method of repair of sliding bearing consisting of two halves includes taking bearing housing out of rotary machine housing, removal of worn antifriction layer and subsequent assembling and mounting of bearing housing into rotary machine housing. When removing antifriction layer, housing of bearing is mechanically machined over inner diameter, and repair shell is fitted in each half of bearing housing after which inner antifriction surface of bearing assembly is machined to provide radial clearance with due account of wear in bearing mounting places on shaft.
EFFECT: reduced time taken by repair and cost of repair of sliding bearings.
