"Storage for Selmeeken conveyors"

Klaus 3? h β there

The invention relates to a bearing for screw conveyors for use between two worm shafts or end bearings.

Are known screw conveyors, their screw shafts be carried in the snow trough by two-part bearings » Depending on the design, these bearings are made of different types of bushings Material provided, for example, cast iron, pock wood or hard tissue; Rolling bearings are also included in the hang-up construction installed in tendon conveyors The previously common bearings of this type have the disadvantage that due to their size they have a large distance between due to the screw blades due to the size of the bearing, as well as the distance between the ends of the interrupted screw, the passage cross-section for the size of the goods to be conveyed is reduced and the flow of goods to be conveyed is delayed or »temporarily interrupted · Another disadvantage is that the plain bearings are all serviced, i.e. must be secured, whereby an absolute seal is not achieved with the current design. Even the salt storage for gourmet storage is not perfect maintenance free.

The purpose of the finding is to store the screw conveyor to make it more economical and to expand the area of application * At the same time, savings should be made achieved and the service life extended

It is therefore the task of the invention to create a new bearing for screw conveyors that in its training is designed more expediently, the distance

between the tendon wings "on both sides of the Bearing is reduced and that the bearing itself has a secure seal *

_{/ V} The object is achieved in that the two hammer bearing screws are sluggish in the cylindrical bearing body, which has the same diameter as the ear shaft, which receives the tendon wing The bearing body is widened inside on both sides of the cylindrical bore to accommodate seals. A sealing ring moved by spring pressure, which is provided with a sliding guide and has a protective groove for receiving lubricating grease, presses the seals continuously, with the individual slemte in the

in their entirety a completely maintenance-free bearing

^ of the largest possible and constant funding space Form with the slightest interruption of the screw. For the support of the bearing body, if necessary, hardly any instead of the Hämgelagerehraubea a narrow one 3? Support arm can be used, which is the same as the bearing - body is designed to be separately exchangeable *

A bearing body 1 is connected, for example, to two cranked hanger bolts 2 by welding. The hangers 2 are taken up in a traverse 3 and versehraubt and held with the nuts 3a. In the bearing body 1, a bearing bush 4, preferably made of plastic, is inserted, in which an intermediate journal 3 runs, which has its largest diameter at the bearing point and is stepped on both sides towards the outside 6 limited. The die ring 7 is guided in an extension of the bearing body 1 and constantly presses with its conically turned parts against the seals 9. The die ring 7 is guided by a pin 10 fixed in the intermediate pin 5 in a sliding guide 10a and pressed on by a helical spring 11 , which rests against the shaft seal ring 6 at the rear. The seals 9 are pressed against a limiting ring 12. In addition to the middle running part and the sealing part, which is stepped on both sides, the intermediate pin 5 also consists of a receiving part on both sides, each of which is mounted in a socket 13, which in turn is inserted into the Jändstüeken of the tubular shaft 14 on both sides of the bearing body 1 is. The Mhrungsbuchse 13 and the tubular shaft 14, which carries the Sckneckenflügel 15 »are firmly connected to each other by hexagonal screws.

The suspension bearing screws are connected to the bearing mechanism. 1 in their height dureli the Adjustable hex nuts. The whole ^ facility is 15 in. between the auger blades an interruption within the snail trough housed

Pressed by the spring-loaded sealing ring 7 once against the limiting ring 12 and on the other hand, due to the conical extension of the limiting ring 12, the outer sealing layer is lifted and thus also axially sealed against the inner wall of the extension 8 in the bearing body. The sealing ring 7 is provided with a protective groove 17 for ett, which further guarantees against the ingress of dust etc. The constant pressure of the die ring 7 is brought about by the helical spring 11, the sealing ring 7 being moved axially against rotation a guide pin fixed in the intermediate pin 5 is provided on both sides, over which the sealing ring 7 moves with its sliding guide 10a «
