Embodiment Construction
[0032] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of devices and methods consistent with aspects of the invention as recited in the appended claims.
[0033] The purpose of the present invention is to overcome the deficiencies of the prior art above, to provide a new type of staggered universal joint device whose rotation diameter of the universal joint is larger than that of the work roll, and further improve the nominal torque and fatigue torque of the universal joint. Torque, prevent the breakage of the universal joint shaft during the working ...

The embodiment of the invention provides an eleven-roller straightener, a main transmission system and a universal spindle system of the main transmission system. The universal spindle system comprises five upper universal spindle devices arranged side by side and six lower universal spindle devices arranged side by side. Each universal spindle device comprises a spline housing, a first spacer bush, a universal spindle and a joint, wherein the universal spindle is provided with a rod body, a first connecting head and a second connecting head, and the first connecting head and the second connecting head are located at the two ends of the rod body; the first connecting head is connected to one end of the first spacer bush, and the spline housing and the joint are arranged at the other end of the universal spindle and the other end of the first spacer bush; the end, far away from the universal spindle, of the spline housing is connected with one roller of the main transmission system of the eleven-roller straightener; and the swing diameter of the universal spindle is larger than that of the roller connected with the universal spindle.
Description
technical field [0001] The invention relates to an eleven-roller straightening machine, a main transmission system of the eleven-roller straightening machine and a universal joint shaft system of the main transmission system. Background technique [0002] During the forming, cooling and transportation of workpieces, due to the influence of various factors, shape defects often occur. In order to eliminate these defects, the workpiece needs to be straightened on a straightening machine. Straightening is to make the curved part of the steel withstand considerable reverse bending or stretching, so that the part produces a certain elastic-plastic deformation. When the external force is removed, the steel undergoes elastic-plastic recovery and then reaches straightness. [0003] According to the straightening method and structural characteristics, the straightening machine can be divided into: pressure straightening machine; roller straightening machine; tube and bar straightenin...
