mechanical engineering; articulated bearings. SUBSTANCE: articulated bearing has inner race with spherical outer surface and outer race with antifriction shim laid in between them. Inner surface of outer race has at least two grooves and dovetail bore which are used for securing elastic antifriction shim on inner surface of outer race; antifriction shim is made from carbon-filled polyamide, type. Bearing may be additionally provided with inner insert made from polymer material. EFFECT: possibility of using in dust-laden rooms; reduced level of noise. 5 cl, 4 dwg |
