DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The subject invention relates to a device in a bearing element devised to support a rotating shaft incorporated in a machine or the like, wherein the bearing housing of each individual bearing element is fastened to a machine member by means of a locking ring formed with a first set of screw holes through which pass a first set of screws, to be anchored to the bearing housing with the machine member sandwiched therebetween.


BACKGROUND

In many machines of various kinds comprising bearing elements to support rotating shafts there is often a need for an attachment means by means of which additional members associated with the machine may be fastened thereto. As examples of such machines may be mentioned conveyors which are provided with bearing elements e.g. at their ends, at which points are additionally required attachment means to secure support legs, scrapers, stripper plates, coupling elements to connect following conveyors, and so on. For this purpose separate attachment points have hitherto been drilled or otherwise provided in the machine frame or side boards, which requires both considerable work and space.


TECHNICAL PROBLEM

The purpose of the subject invention is to eliminate the drawbacks outlined above.


SOLUTION

This purpose is achieved by means of a device in accordance with the subject invention, which is characterized therein that the device comprises at least one retainer element consisting of an attachment plate formed with a substantially circular aperture therein and of a retainer means secured to the attachment plate to fasten a member associated with the machine, and also a clamping ring formed with at least three screw holes and a corresponding number of screws forming a second set of screws, said locking ring formed with a second set of screw holes through which said second set of screws may pass and be secured in the bearing housing, said second set of screws being arranged to extend through the aperture in the attachment plate and being so positioned that said screws, while cooperating with the periphery of said aperture and in conjunction with the locking ring and the clamping ring, serve to guide the retainer element radially as well as axially, said retainer element arranged, when the clamping ring is somewhat loosened, to be turned and set in a selected rotational position relative to the rotating shaft and, when the clamping ring is tightened, to be secured in the selected position by tightening said second set of screws.


BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be described in closer detail in the following with reference to the accompanying drawings, wherein FIG. 1 is a partly broken vertical longitudinal sectional view through a conveyor roller comprising a bearing element equipped with a device in accordance with the invention provided with a retainer element of a first type, FIG. 2 is a lateral view of the device in accordance with the invention, equipped with a retainer element of a second type, FIG. 3 is an exploded view of the device in accordance with the invention comprising a retainer element of said second type, FIG. 4 is a perspective view of the retainer element of the first type, FIG. 5 is a perspective view of a retainer element of a third type, FIG. 6 is a partly broken lateral view of a conveyor equipped with the device in accordance with the invention and FIG. 7 is a partly broken view from below of the conveyor in accordance with FIG. 6.


BEST MODE OF CARRYING OUT THE INVENTION

As appears from FIG. 1, the subject invention uses a bearing element 1 supporting a rotating shaft 2 as the attachment means to fasten one or several different members forming part of a machine or the like, the latter being in the example illustrated a belt conveyor in which a conveyor roller 3 is rotatably mounted in the bearing element 1 by means of a roller bearing 4 which is mounted in a bearing housing 5. The bearing housing 5 is essentially annular and is formed with a central cavity 6 in which the roller bearing 4 is positioned. The rota
