Description

"Device for fastening support bearings in spreader rolls".

The innovation relates to a device for fastening support bearings with a spreader roll consisting of individual pipe sections for flexible ones Material webs.

The spreader rollers for flexible material webs have a rigid one Axis on which the support bearings in the form of central and end bearings at certain intervals are upset. These support bearings are used. around the elastic roll shell, Sheathing hose made of rubber, gunmiähnlichen plastic od. The like., The over pipe sections is drawn to support against the rigid axle.

In more recent times, the support bearings designed as supporting bodies have been used used in the form of roller bearings. It is necessary here, the roller bearing, which consists of inner and outer ring, to be placed and fixed on the rigid axis, so that an axial shift or moving in the circumferential direction is avoided in any case.

For this purpose it is known to use rolling bearings on the rigid axis of the To hold the spreader roller by Seeger rings. It is also known to have the axes on both sides the rolling bearings with a threaded shoulder that can be screwed onto threaded rings, equip Here, however, it is necessary to make the bearing seat larger in diameter and to keep the axis smaller in diameter in front of the thread lugs, in particular in order to be able to slip over the axle. It is also known to the Roller bearing inner ring by so-called. Locking collars as well as possible.

In cases where drawn material is used for the axles of the spreader rolls is used, but it is necessary that the rolling bearing, d. i.e., interior and Outer ring, in a special so-called. To hold housing. The housing consists of it from an inner bush onto which the inner ring is pushed and which over the shaft is striped, and from a nut ring that grips the outer ring of the roller bearing and is set in the pipe section.

With all these known fastenings for rolling bearings results the disadvantage that the type of fastening as such with relatively high Costs associated with it.

Since it is mainly about curved spreader rollers and the peripheral speeds are high, it is essential to lock the roller bearing inner ring on the rigid axle so that it is neither Can move in the axial direction and in the circumferential direction and it is avoided that possibly the roller bearing inner ring relative to the rigid axle during operation Movements.

The object of the innovation now aims to avoid these disadvantages by disclosing a device which allows the roller bearing to be properly fixed. For this purpose, the innovation consists in the fact that the support bearing designed as a support body in the form of a roller bearing consisting of an inner and an outer ring is held in a bushing detachably connected to the axis, the outer ring by a sheet metal od. The like. curved separate deep-drawing jacket, which is supported against the pipe section and punctured (spot welding) is held.

The inner ring of the roller bearing is expediently once through a Approach to the socket and to the other by a screw that the Bushing releasably connects to the axle and at the same time in relation to the roller bearing fixed in the axial direction, supported.

The outer ring of the roller bearing is held in such a way that it rests on one side is supported against the wall of the deep-drawn jacket and on the other Side od a sealing disk, the like is interposed, which can be flanged by several Noses is clamped.

The deep-drawn jacket is spot-welded to the pipe section tied together.

The parts that comprise the inner and outer ring are advantageous Hold existing bearings on the axle, made of metal, plastic or the like. Material manufactured.

An embodiment of the subject of the innovation is shown in the attached sectional drawing. According to the drawing, the axis is denoted by 1 {2 The rolling position, consisting of inner and outer ring 3, sits on a socket 4. The socket 4 has on the one side has a shoulder 4t and is detachably connected to the shaft 1 on the other side by a screw 5. The screw 5 simultaneously has the task of locking the inner ring 2 on the socket 4, in that the screw head presses the inner ring 2 against the shoulder 4 ′. The sleeve ring 3 is mounted in a deep-drawn casing 6 drawn from sheet metal or the like. The deep-drawn jacket 6 has a pulled-down edge 6 'on one side. A sealing washer 7 is interposed on the other side and is clamped in place by several lugs 6 ″ that can be crimped.

The deep-drawn jacket 6 is fastened to the pipe section 8 also by spot welding 9.

In the pipe section 8 a bore 10 is provided through which the screw 5 can be pushed through from the outside.

The pipe sections 8 are in a known manner by the slipped over elastic WaAsmmantel 11 wrapped.

The individual parts according to the innovation, bushing and deep-drawn casing 4, 6, are made of metal or plastic.

The object of the innovation has the advantage that it is suitable for the Rolling bearings to support the pipe sections no longer necessary is to use so-called housing, but only required a Inner bushing and a so-called deep-drawn casing made of sheet metal or the like can be, which is dotted with the pipe section by Sctma-ssung, to use. This results in comparison with the known devices for fastening the support bearings with spreader rolls considerably lower production costs, which is with consideration very inexpensive due to the large number of support bearings used affects the total costs of the individual spreader rolls. On top of that, It is now also possible to use drawn, commercially available material as the axis, so that the total costs of the spreader roll continue to rise Reduce.

Due to the special design of the deep-drawn jacket, namely, that it has a very far inward drawn edge on one side and ground that a so-called sealing washer is placed in front of it on the opposite side the / guarantee that the roller bearing against dust, barrels and other unpleasant Influences from the outside are protected, and as a result, the fat is also present held in the roller bearing, so that the life of the roller bearing is very strong is increased.
