Abstract

Изобретение относитс к производству валковых машин и может быть использовано в промышленности строительных материалов дл обработки керамических масс. Цель изобретени - снижение трудоемкости замены бандажа и металлоемкости последнего. Валок состоит из вала 1, на котором смонтированы неподвижна ступица 3 и подвижна ступица 4, соединенна с гайкой 5, балок 7, шарнирно соединенных со ступицами рычагами 8 и 9, и бандажа 6, опирающегос на балки 7. Рычаги 9 выполнены двуплечими и снабжены ограничительными винтами 11, предохран ющими балки 7 от осевых смещений. Балки соединены между собой при помощи планок 12 и направл ющих 13. При перемещении ступицы 4 по направлению к ступице 3 или от нее соответственно увеличиваетс или уменьшаетс угол между рычагами и осью валка. При этом рассто ние между диаметрально расположенными балками увеличиваетс или уменьшаетс , что позвол ет обеспечить плотное прилегание бандажа по всей опорной поверхности балок 7 и легко произвести замену бандажа. 3 ил.The invention relates to the manufacture of roller machines and can be used in the building materials industry for the treatment of ceramic materials. The purpose of the invention is to reduce the laboriousness of replacing the bandage and the metal intensity of the latter. The roller consists of a shaft 1 on which a fixed hub 3 and a movable hub 4 mounted to a nut 5 are mounted, beams 7 pivotally connected to the hubs by levers 8 and 9, and band 6 supported on beams 7. The levers 9 are double-shouldered and equipped with restrictive screws 11, which protect the beams 7 from axial displacements. The beams are interconnected by means of strips 12 and guides 13. When moving the hub 4 towards or away from the hub 3, the angle between the arms and the roll axis increases or decreases accordingly. In this case, the distance between the diametrically located beams increases or decreases, which allows for a tight fit of the bandage over the entire support surface of the beams 7 and it is easy to replace the bandage. 3 il.

Claims

Claim

A roll of rollers comprising a shaft, hubs mounted on it with support elements on which a bandage is installed, characterized in that. in order to reduce the complexity of replacing the bandage and the metal consumption of the latter, the supporting elements are made in the form of beams radially and evenly spaced on the surface of the bandage and pivotally connected to the hubs using levers, at least two of which are two shoulders, and their free shoulders are equipped with 'restrictive screws, in contact with the inner surface of the beams installed one relative to another with the possibility of radial movement using transverse strips fixed to even beams, the ends of which are obviously s in guides arranged on the odd beams, wherein the lever arm connecting the beam to the hubs, are connected with the latter by means of hinges, and the distance between the hinge arms on the hubs greater than the distance between the hinges on the beams, and one of the hubs is mounted for movement along the shaft.
