Description

Technical Field

[0001] The utility model relates to a finishing mill cone box, in particular to a tool for detecting the axial movement of a vertical shaft bearing of a finishing mill cone box. Background Art

[0002] The finishing mill is a key equipment for rolling high-speed wire products. The cone box is a closed speed increaser mechanism and is the core component of the finishing mill. The cone box is equipped with a bevel gear set composed of a vertical shaft bevel gear and a long shaft bevel gear. The rotation of the long shaft drives the vertical shaft to rotate, and the helical gear on the vertical shaft drives the helical gear of the roll box to rotate. Rollers are installed on the roll gear shaft of the roll box to meet production rolling requirements.

[0003] At present, during the daily inspection and maintenance, when detecting the axial movement of the vertical shaft bearing, due to the small space inside the cone box of the finishing mill, there is not enough space at the helical gear position to use a slightly larger tool to pry. At the same time, the vertical shaft bearings are installed in pairs of upper and lower parts. During inspection, only the status of the upper bearing can be observed by eye, while the lower bearing cannot be observed. Therefore, it is impossible to understand the bearing movement, and thus it is impossible to grasp the working status of the vertical shaft of the cone box of the finishing mill. There is a point of loss of control in the equipment. Once a fault occurs at this position, it is very easy to cause major accidents such as tooth breaking of the cone box bevel gear set of the finishing mill, which seriously restricts production operations.
