Abstract

PURPOSE:To stably install brush discs by arranging a plurality of wedge tightening means having specific constitution onto the peripheral surface of a shaft, in a brush roll which is formed by installing a number of brush discs onto the shaft. CONSTITUTION:A number of brush discs 1 made from a thin metal plate having surface-treated fibers 2 planted onto the outer peripheral surface are installed onto a shaft 3. Flanges are installed onto the both sides of a brush-disc 1 parallel arranged body, and restrained in the direction of axis line with respect to the shaft 3 by a snap ring 5, flange pressing 6, and a tightening bolt 7. In this case, a plurality of wedge tightening means 8 are arranged at a uniform angle onto the peripheral surface of the shaft 3. In said wedge tightening means 8, a key 10 having a tapered groove 9 is fitted into a key way 13 and connected onto the shaft 3, suppressing turning, by the tightening by a machine screw 14, and a tapered cutter 11 is fitted into the tapered groove 9, and a key 12 is fitted into a key way 15, having the tapered cutter 11 superposed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention I is a flagyl roll, in particular, a surface-treated fiber, such as abrasive thread, kumpiko fiber, or nylon thread, is coated on the outer peripheral surface.
A brush disk made of a thin metal plate is mounted on the shaft.
This invention relates to a brush roll mounted by laminating and pressing a large number of sheets.

Such a brush roll is conventionally known, and since the roll itself is composed of a parallel body of brush disks formed by laminating and pressing a large number of brush disks, it can be easily manufactured even in the case of a long item. However, on the other hand, due to the need for space to quickly press the brush disk fitted onto the shaft by pressing 17, and to remove the worn brush disk when replacing it with a new one, the shaft and plan disk There must be a relatively large gap with a diameter difference of about 0.8 to 1.0 mm between the brush roll and the high-speed rotation (900 mm).
During brushing at ~120 Or, p, m), the brush disk parallel body vibrates slightly with respect to the shaft, causing chatter marks to occur on the treated surface of the treated material, such as a metal strip that has been surface-treated by polishing or cleaning. there were.

Therefore, the present invention overcomes the problems caused by the special circumstances of the front legs of the brush roll of the above-mentioned type, ensures that the brush disc parallel body is mounted on the shaft under stable conditions without slight vibrations, and moreover, it is possible to do this in a simple manner. The aim is to achieve this.

The plan roll of the present invention has 8 surface-treated fibers on the outer peripheral surface.
For example, in a brush roll in which a large number of brush disks made of thin metal plates to which Kunpico fibers, nylon threads, and abrasive threads are attached are laminated and pressed onto a shaft, the length is connected to the bottom of the shaft. The components include a key with a tapered groove along the direction, a tapered razor blade fitted in the Dever groove of the key, and a key fitted in the key groove of the parallel body of the brush disks stacked on the tapered razor. It is characterized by a plurality of wedge tightening means including . It can be used for brushing processes such as scale removal and molding sand removal.

According to the present invention, a plurality of tapered razors in the wedge tightening means arranged at appropriate angles on the circumferential surface of the shaft are pushed in a desired direction by the taper angle of the key with a taper groove. By the wedge tightening action of the razor blade and the tapered groove in which it is fitted, the key in the keyway of the parallel body of brush disks on the shaft is pressed against the center side of the parallel body of brush disks, and thereby the brush disk is pressed against the shaft. Tighten and restrain parallel objects.

As described above, according to the present invention, since the brush disk parallel body on the shaft is tightened and restrained under wedge tightening, the brush disk parallel body is held at 7° relative to the shaft when the brush roll is rotated.
It is guaranteed that a stable and firm mounting condition without slight vibrations will be generated, and the brush disc will be tightened by the taper groove of the taper grooved key and the taper razor fitted thereto. It is ensured that the tightening and restraint of the parallel body can be finely adjusted in each wedge means and that this is achieved simply.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, (1) is a brush disk made of a thin metal plate with surface-treated fibers (2) such as tampico fibers, nylon threads, and abrasive threads flocked on the outer circumferential surface, and (3) is a lamination of many brush disks (1). The shaft is attached by pressing, and the flange retainer (6) and bolts (7) are used to tighten the shaft (3).
An axial constraint can be applied to.
