"Ring body for holding and simultaneous axial tensioning of machine elements"

The! Inflation refers to a ring body for. Keep and simultaneous axial clamping of machine elements.

For this purpose, as an aid to supporting the interior Elements (bearings and seals) of I conveyor belt idlers to each other, but also for numerous other purposes, Seeger rings are used in the Hegel.

These rings, which are open on one side, are placed in the ring grooves of the bearing housing s or the like used. Their effect is limited but on securing the supported element against axial displacement «

In many cases, however, it is 'n;': i to be achieved that the elements held by the King, e.g. 3. In the application mentioned above, the inner ropes of conveyor belt rollers lie one inside the other without play, it is desirable to simultaneously exert an axial pressure effect on this element. For this purpose, hanging bodies made of spring wire are already known ₉ which are also used in annular grooves in the bearing housing or the like and the wire ends of which are bent out of the plane of the hanging body when this body is set into the hat receiving it to the resilient aclisial pressing system on the element to be supported.

Resilient ring bodies of this type are very useful in practice well proven. 3s, however, have certain disadvantages.

The most important of these disadvantages is that there is only a point-wise contact of the liind areas bent out of their plane to act on the element to be supported under a correspondingly high specific surface pressure, which leads to rapid fatigue of the fire effect. Furthermore, these support points are particularly high G-rs.de the G-AAGER of Terrostens exposed to ₉ which also leads to Yerlust the clamping force of the resilient Hing body and thus the "ineffective are its aclisialen Yerspannungswirkung"

Hin further ITachteil the known Hing body is the _s that they tend to be out of the receiving them! Tut under the "/ MPACT the counterpressure to which they are exposed, heraussus-O-Ringen.

In order to prevent this, the groove has to be cut comparatively deep will.

As a result of the fire, a resilient ring body becomes the one last described Design created, the design of which avoids these difficulties and disadvantages «

'This is achieved according to the basic idea that! that the one-sided open ring body consisting of elastic 'Merkstoff has a rectangular profile and a plurality of has tab-like resilient lugs extending from the inside of the profile.

Due to the rectangular profiling of the ring, it is also _{reliably held in a hat that is less deep, for example pierced only to half of its radial width 9,} against the risk of popping out in all of a round-profiled body. Furthermore, there is a two-dimensional contact j ±] 2s:. * 2t2i on the element to be supported by the part of the pike corner profile located outside the LTut. The fact that the parts of the singing body lying resiliently against the surfaces of the element to be supported are no longer formed by bent-out end parts of the same, but by tabs extending from the inside of the ring body, results in a much better distribution of the

Ring body itself rafts on increasing ^ls "or, conversely, the pressing forces and a face contact on the bodies to be supported, with a correspondingly lower surface pressure.

The tab-like extensions are preferably at the ends

the
of the ring body and on / between the opening opposite the same, ie there are preferably three such approaches, of which those adjacent to the opening of the ring are provided with the usual through-holes for engaging a mounting tool.

According to a special feature of the innovation are - with the Result of an even better pressure distribution or »Yer size-r tion of the pressure-transmitting surfaces - the protruding lobes extend inward from their root on the ring body They are tapered, i.e. they basically have a circular profile.

The formation of the ring body according to the hiring makes it possible to manufacture this as a one-piece, integral molded body from a suitable, resilient 7 / material. A particularly suitable material for this is a hard plastic with corresponding resilient ^ w2jigenscha.f-

Use of this or one of the properties equivalent to it having animal material has besides the simplified production possibility of the ring / body by injection molding the advantage of its absolute corrosion protection and thus practically table unlimited shelf life, / without reduction or deterioration its resilient properties.

A preferred embodiment of the new hanging body is shown in the pictures »

The shoulder a' is on the side opposite the opening of the ring body and thus where the ring body is exposed to the greatest bending stress and thereby reinforces the ring body at this most important point.
