Carrousel coiler with reel that can be replaced rapidly

Abstract

A carrousel coiler with reels that can be replaced rapidly comprises a revolution gearbox, two reels which have completely same structures except installation positions of drive gears, and corresponding driving shafts; jacket cups are disposed at one side of each real near an expanding-collapsing cylinder and one side near the real; a bearing is disposed inside each jacket cup; the inner ring of the bearing is positioned by a shaft sleeve and a spacer ring in the axial direction, and the outer ring is fixed in the jacket cup by a spacer ring, a gland, and an inner shoulder shaft in the axial direction; four hydraulic cylinders press the outer edge of the jacket cup at the reel side to a case body, and the hydraulic cylinders are connected to the revolution gearbox by bolts. According to the invention, the reels can be dismounted or mounted by applying axial force, and miscellaneous work caused by dismounting the case body and a left and a right end covers is omitted; time required for replacing the reels is greatly shortened; not more than half an hour is needed for replacing a reel; and the maintenance cost is greatly decreased.

Description

technical field [0001] The invention relates to a steel strip coiler. Background technique [0002] As a rotatable double-drum coiler, the Carousel coiler has become the preferred coiling equipment for many cold tandem rolling production lines due to its advantages of high production efficiency and small footprint. The revolving gearbox is its key equipment. The divided revolving gearbox is equipped with two reel shafts and corresponding drive shafts inside, which are responsible for the rotation and revolution of the two reel shafts. [0003] The revolving gearbox is a split structure, the upper and lower boxes are symmetrical about the split plane, and the reel shaft is located in the shaft hole of the split plane. The two bearing holes (expansion and contraction cylinder end, reel end) that the revolving gear box cooperates with the reel shaft respectively have a shoulder and a bearing cap to cooperate with the bearings supported at both ends, so as to realize the fixed ...

AI Technical Summary

Problems solved by technology

The reason why it takes a lot of time to replace the reel: 1. The size of the revolving gearbox is large (radius 1920 mm), and the weight is heavy (16.4 t for one box); 2. There are many bolt connections between the upper and lower boxes, and the box and the bearing cover There are many bolt connections between them; 3. For the double-row tapered roller bearings used in the original design, the gap adjustment work is cumbersome and time-consuming

On-site operation takes more than ten hours
