High temperature-resisting V-type differential steering roller

Abstract

The invention relates to a V-type differential steering roller for producing painted steel strips for packaging. The V-type differential steering roller comprises bearing base plates, bearings, a rotating shaft, a steering roller body, retainer rings and rotating connectors, wherein the bearings and the rotating shaft are arranged on the bearing base plates, the rotating shaft is sleeved with thesteering roller body, the retainer rings are arranged at the two ends of the steering roller body, and the rotating connectors are arranged at the two ends of the rotating shaft. The V-type differential steering roller is characterized in that the rotating shaft is a hollow water-cooled shaft, the steering roller body is a V-type differential steering roller body, and the V-type differential steering roller body is composed of a plurality of V-type differential steering roller pieces arranged on the hollow water-cooled shaft in a sleeving mode, rolling bearings and spacer bushes. The V-type differential steering roller has the advantages that since the multiple V-type differential steering roller pieces are combined to form the V-type differential steering roller body, each steering rollerpiece can independently rotate, and the situation that steel strips are not uniform in tightness degree and production accidents occur in the production process is effectively avoided; and due to thedesign of the hollow water-cooled shaft, the V-type differential steering roller pieces have the properties of high temperature resistance and deformation resistance.

Description

technical field [0001] The invention belongs to the technical field of steel strip turning rolls, and in particular relates to a V-shaped differential speed turning roll that can withstand high temperatures on a production line of painted steel strips for packaging. Background technique [0002] The existing production line for the production of painted steel strips for packaging, in the process of producing painted steel strips for packaging, generally goes through raw materials-uncoiling-cutting and striping-heating bluing-surface painting-heating and drying-coiling And other processes, and in the production process, whether it is heating bluing or paint drying, it is necessary to turn the steel belt through the turning roller. The steel strip turning rolls used in the conventional production of painted steel strips for packaging generally adopt integral flat rolls. Because the raw steel coils have different degrees of difference in the same plate, after cutting and slitt...

AI Technical Summary

Problems solved by technology

In the production process, after the steel strip is heated to blue or heated and dried, it needs to be turned by the turning roller. At this time, the temperature of the steel strip is very high, and the general integral flat roller is used for turning. Due to the reason of thermal expansion, the turning roller The bearing will expand and lock, causing the steering roller to stop and cause production accidents
