1,089,711. Brushes for rolling mills. LOEWY ROBERTSON ENGINEERING CO. Ltd. Feb. 17, 1966 [Feb. 22, 1965], No. 7640/65. Heading A4K. A cylindrical drum (1) of a steel wire rotary brush 2, for cleaning the surface of a working roll in a rolling mill, is driven by an internal hydraulic motor (5) of the impeller type. The motor is rigidly mounted on the end of one stationary shaft (3) of the brush. Preferably, a relatively slow axial oscillation of the brush is simultaneously effected, by means of a planetary reduction gear 26, carried on a non- rotatable axially movable sleeve 23, keyed to the other stationary shaft 4. The rotation of the brush 2, on the bearings 24, is imparted to the input shaft 27 of gear 26, so that the output shaft 30 drives link 34 around its eccentric bearing 37. The varying inclination of the link produces oscillatory axial motion of the parts 30, 26, 27, 29, 23, 25 (1) and 2. |
