Rapid repairing method for loosening of water retaining ring of roller

Abstract

The invention belongs to the technical field of machinery, and relates to a quick repairing method for loosening of a water retaining ring of a roller, the water retaining ring is arranged on a shaft neck of the roller, and a sealing ring is arranged between the water retaining ring and the roller, and the quick repairing method comprises the following steps that after the water retaining ring is detached from the roller, the assembling contact range of the water retaining ring and the roller neck is measured, and a roller neck repairing area is determined; the width of the roller neck repairing area is controlled to be 5-10 mm larger than that of the water retaining ring; a roller neck repairing area is machined, a net-shaped groove is machined in the circumferential direction of the roller neck repairing area, the roller neck repairing area is evenly coated with a rapid repairing agent, the net-shaped groove is filled with the rapid repairing agent, and the coating thickness ranges from 0.3 mm to 0.5 mm; the water retaining ring is heated, a sealing ring is installed, and the water retaining ring is arranged on the roller neck in a sleeving mode so that the water retaining ring can be tightly attached to the roller; and after standing and curing, the bearing seat is sleeved, and the process is finished. According to the invention, the quick repairing agent is adopted to realize quick repairing of the loosened roller water retaining ring, parts do not need to be prepared again, quick repairing of the roller water retaining ring can be realized, and the quick repairing agent can be quickly put into production and use.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a quick repair method for loose water retaining rings of rolls. Background technique [0002] The water retaining ring of the work roll of hot continuous rolling and finishing rolling is sometimes loose. After the water retaining ring is loose, the cooling water of the rack can directly enter the bearing box, which may cause pollution of the bearing box at light cases, increase the maintenance of bearing assembly, and cause burnout of roll bearings at severe cases. damage. The water retaining ring and the roll neck are an interference fit. When the water retaining ring is loose, the cost of re-preparing the water retaining ring is high and the repair time is long, which affects the number of spare rolls produced. Contents of the invention [0003] In view of this, the object of the present invention is to solve the problem of roll water retaining ring loosening, and to provide...
