The invention discloses a gear distribution box of a main transmission device of a periodic pipe mill. The gear distribution box comprises a lower box and a box cover covering the lower box, wherein a first groove and a second groove which penetrate through the front part and the rear part are respectively formed in at least one pair of corresponding connection surfaces of the lower box and the box cover; the first groove and the second groove define an accommodating through slot; and a wedge block adjustment device for adjustably and fixedly connecting the lower box and the box cover together is arranged in the accommodating through slot. In order to integrate the box cover and the lower box together, the wedge block adjustment device replaces the conventional mode based on a bolt and a nut which have large diameter. Therefore, the gear distribution box is easy to connect, low in processing cost, high in production efficiency, high in mounting stability and reliability and easy to maintain.
Description
technical field [0001] The invention relates to a transmission device of seamless steel pipe production equipment, in particular to a gear distribution box of the main transmission device of a periodic pipe rolling mill. Background technique [0002] The periodic pipe rolling mill is the most important equipment in the large-diameter seamless steel pipe production line. Its function is to thin the pipe wall of the perforated hollow capillary pipe and control the wall thickness of the inner and outer diameters. Each rotation of the roll of the periodic pipe rolling mill is called a rolling cycle, and the numerous rolling cycles will roll the capillary longitudinally section by section into pipe fittings with geometric dimensions that meet the requirements. The main transmission device of the periodic pipe rolling mill includes a motor, a reducer and a gear distribution box, etc., and the main transmission device is the power guarantee for metal deformation. [0003] like Fi...
