FIELD: machine building.
SUBSTANCE: invention relates to a trunnion bushing as part of a bearing with an oil film in a rolling mill. Trunnion bushing serves to receive the taper trunnion of the roll. Trunnion bushing features the following dimensions: 0.35<3.6/a (DB)+kD<0.5, where D is the outer diameter of the trunnion bushing working surface; a is the projected length of the conical longitudinal section of the trunnion bushing; k—coefficient of sliding; B is the large diameter of the trunnion bushing cone.
EFFECT: as a result, a gap for a lubricating film is formed between the inner side of the trunnion bushing and the outer surface of the roller trunnion and at the same time the occurrence of large axial forces is prevented.
