Helical rolling mill roll line for producing die-rolled sections and solids of revolution

摘要

Output shafts of a pinion stand are connected with rolls of a working stand by means of spindles provided with a shaft whose ends are formed with Hooke's joints. The angles of obliquity of the shafts of the spindles are similar for all the joints of the spindles. The axes of the output shafts of the pinion stand are equidistant from the axis of rolling. The angular space relationship of the pinion stand with the working stand, i.e. the angle of inclination of the plane, passing through the axis of rotation of the output shafts and through geometrical axis of the pinion stand, to the plane passing through the axis of rolling and through the axis of a variable angle of rolling, is determined by a formula.
