SLIDING BEARING FOR ROLLING MILL Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: sliding bearing consists of antifriction and construction layers, the ratio of thickness of the layers being in the range from 1: 1 to 1:14. The antifriction layer is made of composition material. The composition of the material is presented in the invention description. The construction layer is monolithic or perforated from the side of the bearing housing and made of layered or randomly armored fiber glass or fabric-based laminate. The perforation holes of the construction layer are circular, oval, square rectangular, and so on. The depth of perforation holes is 0.1-0.8 of the thickness of the construction layer, the ratio of the perforation area to the area of material being from 1:5 to 6:1. EFFECT: enhanced longevity, lowered wearing, enhanced resistance to shock loads. 2 cl, 2 dwg
