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. ...

Embodiment Construction

[0008] like figure 2 As shown, the present invention includes a roll neck 1 and a bearing 2, the roll neck 1 is installed on the bearing shell 3, the bearing seat 7 is fixed on the bearing 2, an oil injection port 8 is opened on the bearing seat 7, the bearing 2 is fixed on the end of the roll neck 1, Both sides of the bearing 2 are fixed with a bearing cover 4, which also includes a labyrinth ring 5 and a retaining ring 6. The corresponding gap between the bearing cover 4 and the labyrinth ring 5 is engaged, which can play a role in relief. The retaining ring 6 is fastened by screws 9 The labyrinth circle 5 on one side is further consolidated to ensure that oil cannot seep out, thereby improving production efficiency.
