摘要： PROBLEM TO BE SOLVED: To provide an improving method of a hydraulic driving device for urging an oil film bearing onto and off of a roll neck. SOLUTION: A hydraulically actuated piston/cylinder unit 50 is mounted on a cylindrical section 56 of a roll neck. The cylindrical neck section is delimited at one end by a circular shoulder 20 on the roll neck 12, and at the opposite end by a circular groove 22 in the roll neck 22. A retaining ring 66 has lock arms pivotally movable into seated positions in the groove 22. The piston/cylinder unit is operable in a first mode in an abutting relationship with the lock arms to urge the bearing 36 onto the roll neck 12, and is operative in a second mode in an abutting relationship with the shoulder 20 to urge the bearing 36 off of the roll neck 12. The piston/cylinder unit and the lock arms having complimentary tapered surfaces arranged to coact in urging the lock arms inwardly into their seated positions in response to the abutment of the piston/cylinder unit with the lock arms.

摘要： An oil film bearing for a roll neck (12) in a rolling mill, comprising a bearing chock (24), containing a bushing (22) having a lining of babbitt metal. A sleeve is removably received on and rotationally fixed relative to the roll neck. The sleeve is journalled for rotation within and is axially shiftable with respect to the bushing. An abutment (56b) protrudes radially from an exposed outboard end of the sleeve for engagement by an outboard end face of the bushing during axial removal of the bearing from the roll neck. The lining of babbitt metal is recessed axially inwardly from the bushing outboard end face by a distance sufficient to prevent it from being damaged by engagement with the radially protruding abutment.

摘要： Un aparato para colocar y remover de un cojinete de película de aceite del cuello de un rodillo en una laminadora, que comprende una unidad de pistón/cilindro anular accionada hidráulicamente montada sobre una sección cilíndrica del cuello de rodillo. La sección cilíndrica del cuello está delimitada en un extremo por medio de un hombro circular sobre le cuello de rodillo y en el extremo opuesto por medio de una ranura circular en el cuello del rodillo. Un anillo retenedor que tiene brazos de sujeción que se mueven pivotalmente en posicione asentadas en la ranura, la unidad de pistón/cilindro puede operarse en un primer modo en una relación empotrada con los brazos de sujeción para empujar al cojinete en el cuello del rodillo, y que pueden hacerse operar en un segundo modo en una relación empotrada con el hombro para retirar el cojinete del cuello de rodillo. La unidad de pistón/cilindro y los brazos de sujeción tienen superficies ahusadas complementarias colocadas para hacer contacto con los brazos de sujeción hacia adentro en las posiciones asentadas en respuesta al empotrado de la unidad de pistón/cilindro con los brazos de sujeción.

摘要： An apparatus for urging an oil film bearing onto and off of a roll neck in a rolling mill comprises an annular hydraulically actuated piston/cylinder unit mounted on a cylindrical section of the roll neck. The cylindrical neck section is delimited at one end by a circular shoulder on the roll neck, and at the opposite end by a circular groove in the roll neck. A retaining ring has lock arms pivotally movable into seated positions in the groove. The piston/cylinder unit is operable in a first mode in an abutting relationship with the lock arms to urge the bearing onto the roll neck, and is operative in a second mode in an abutting relationship with the shoulder to urge the bearing off of the roll neck. The piston/cylinder unit and the lock arms having complimentary tapered surfaces arranged to coact in urging the lock arms inwardly into their seated positions in response to the abutment of the piston/cylinder unit with the lock arms.
