Embodiment Construction

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] like figure 1 As shown, the side guide roller of the present invention mainly includes a roller housing 1 , a roller body 2 , a fixed pin 6 , a moving shaft 7 and a fixed shaft 8 .

[0019] A first bearing 102 and a second bearing 103 are installed inside the roller base 1 . Wherein, the first bearing 102 adopts an impact-resistant cylindrical roller bearing, which can withstand a large radial impact force brought by the slab; the second bearing 103 adopts a self-aligning roller bearing to bear axial force. The inner ring of the bearing is sleeved on the fixed shaft 8, and the fixed shaft 8 can only rotate, and its fixing method adopts lock nuts etc. to fix on the top of the roller seat 1.

[0020] The fixed sh...

Abstract

The invention relates to a side guide roller. The side guide roller comprises a roller body, a roller seat, a fixed shaft and a moving shaft, wherein the fixed shaft is mounted in the roller seat, the moving shaft is inserted in the fixed shaft and rotates along with the fixed shaft, the lower end of the moving shaft is sleeved with the roller body, a through hole is formed in the upper end of the moving shaft, a spiral guide groove is formed in the upper part of the fixed shaft, the upper part of the moving shaft is fixedly connected with the upper part of the fixed shaft by the aid of a connecting piece, and the connecting piece penetrates through the through hole to be inserted into the spiral guide groove. The position of the side guide roll can be adjusted online, the problem of concentrated wear in one position of the roller surface of the side guide roller is solved, and the service life of the side guide roller is prolonged.

Description

technical field [0001] The invention relates to the field of hot-rolled steel strip production equipment, and more specifically relates to a side guide roller. Background technique [0002] At present, in the production process of ordinary hot-rolled strip steel, in order to meet the requirements of the production process, the units are equipped with different numbers of side guide devices. The side guide rollers on both sides pinch the deviation strip in opposite directions to guide the strip, reduce the deviation of the strip during operation and make it run straight, especially when the strip is threaded and flicked, the side guide device Particularly important. In the side guide device, the part that guides and corrects the deviation of the strip is the side guide roller. Since the deviation-tracked strip runs at a faster speed, it produces dual effects of radial friction and axial runout friction on the side guide roller. Due to the downward gravity of the strip steel...
