Locking device for vacuum turning roll

Abstract

The invention provides a locking device for a vacuum turning roll, which effectively solves the problem of oil leakage due to oil pressure during oiling, saves the cost and largely improves the production efficiency. The locking device comprises a roll neck and a bearing, wherein the roll neck is arranged on a bearing shell, a bearing block is used for fixing the bearing, an oiling opening is arranged on the bearing block, the bearing is fixed at the end part of the roll neck, and bearingcaps are fixedly arranged on the two sides of the bearing. The locker further comprises maze-shaped rings and a retainer ring, wherein the bearing caps and the maze-shaped rings are clamped through corresponding intervals, and the retainer ring fastens the maze-shaped ring on one side through a screw.

Description

technical field [0001] The invention relates to the technical field of papermaking machinery and equipment, in particular to a locking device for a vacuum return roll. Background technique [0002] For the working environment of the paper machine, its mechanical equipment also needs regular lubrication, such as figure 1 As shown, the existing lubrication is to open an oil injection port 8 on the end face of the bearing seat 7 fixed on the bearing 2, the roll neck 1 is installed on the bearing shell 3, and the bearing cap 4 is fixed at both ends of the bearing 2, and the bearing cap 4 is screwed It is fixed on the journal 1, but after oil filling, due to the relationship of oil pressure, the oil is likely to seep through the gap between the bearing 2 and the bearing cover 4, and the gap between the bearing cover 4 and the journal 1, which not only causes oil leakage Waste, seeping oil may also affect the printing of paper, affect production, and cause economic losses. ...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems, the present invention provides a locking device for the vacuum return roller, which effectively solves the problem of oil leakage due to the oil pressure during oil injection, saves costs and greatly improves production efficiency

[0005] The beneficial effect of the present invention is that the oil is injected into the oil injection port, and the gap between the bearing cover and the labyrinth ring can play a role of relief, effectively solving the problem of oil leakage due to the oil pressure during oil injection, and the retaining ring is fastened by screws. The labyrinth ring on the side is further consolidated to ensure that the oil cannot seep out, thus improving production efficiency
