Abstract

Изобретение относитс  к прокатному производству и может использоватьс  в подшипниковых опорах прокатных валков, содержащих подшипники жидкостного трени . Цель изобретени  - повышение долговечности подшипника путем обеспечени  надежности смазывани  конической поверхности втулки - цапфы. При работе подшипника образуетс  зазор у одного из торцов втулки-цапфы 1. В каналы 7, размещенные у данного торца, прекращаетс  подача смазки. В каналы 7, расположенные у противоположного торца, смазка поступает. Это обеспечивает надежность смазывани  трущихс  поверхностей, уменьшаетс  износ, повышаетс  долговечность. 6 ил.FIELD OF THE INVENTION The invention relates to rolling production and can be used in bearing supports for rolling rolls containing liquid friction bearings. The purpose of the invention is to increase the durability of the bearing by ensuring the reliable lubrication of the conical surface of the bushing - axle. When the bearing is in operation, a gap is formed at one of the ends of the bush-bearing 1. The channels 7 placed at this end stop the supply of lubricant. In the channels 7, located at the opposite end, the lubricant flows. This ensures the reliability of lubrication of the running surfaces, reduces wear, increases durability. 6 Il.
