Abstract

The invention relates to a corner gearbox for a single-rack driving steel pipe stretch reducing mill. The corner gearbox comprises a box body, wherein two groups of power transmission systems of which the rotating directions are different penetrate through the box body in a sealing mode, the power transmission systems respectively comprise power input shaft systems and power output shaft systems, the output ends of the power output shaft systems respectively comprise external drum-type gears which can be connected with a milling rack, telescopic control parts respectively communicate with the other ends of the power output shaft systems, output shaft hole channels through which the power output shaft systems penetrate are formed in the box body, the power output shaft systems comprise hollow power output shafts, output shaft system bevel gears fixedly sleeve the power output shafts respectively, and the power output shafts are rotatably supported in the output shaft hole channels by virtue of output shaft bearing structures which sleeve both sides of the output shaft system bevel gears. According to the corner gearbox, the problem of unstable output shafts in the prior art is solved, and the stress optimization of the power output shaft systems is realized, so that the whole structure is stable.

Description

technical field [0001] The invention relates to seamless steel pipe production equipment, in particular to a corner gear box for a single-frame transmission steel pipe stretching and reducing machine. Background technique [0002] The steel pipe stretching and reducing machine is a kind of equipment used for hollow rolling of the blank pipe after perforation and continuous rolling. At present, the steel pipe stretching and reducing machine mostly adopts the three-roller type, and the three rolls are 120° to each other. The rolling stands are arranged in sequence according to the Y shape and the inverted Y shape. The number is generally 24 to 28. Through power distribution, each The three rolls of the rolling stand have the same rotational speed. The number of stands is set according to the rolling process, and the corresponding pass series is selected. By controlling the roll speed, different tensions are applied to each section of the steel pipe. Under the joint action of ...
