A coil steel chain of the above type is known in which the cheeks of the inserts are beveled and dimensioned so that their side surfaces form wedge spaces with the chain links connected to one another via the insert Promoting contact surfaces of inserts and chain links «The underlying task of inflation is to design the inserts in a round steel chain of the type described at the beginning so that the disadvantage described does not occur and a significant increase in the service life of the chain is achieved. This object is achieved in that the angle of contact of the inserts is 180 ° -2p , with the maximum joint deflection between two successive links during the run over a chain wheel.

In the round steel chain according to the innovation occur between the Chain links and the inlays do not have any harmful wedge spaces. The edges facing the chain links Rather, the end faces of the inserts are flush with the chain links and thus prevent foreign bodies from entering in the storage areas.

The strength of the insert depends to a certain extent on the intended use off the chain. However, an embodiment has proven to be particularly advantageous in which the insert in the The area between the chain links has a strength which is equal to half the difference between the chain link strength and the clear width of the chain links.

The angle of wrap pt, which is the one given above Amount, values are generally given in

of the order of 160 °. He should go after possibility not be less than 90 ° to the specific The burden ¥ </ which is exerted on the deposits is slight to keep. The wear at the joints of the chain can also be reduced by removing the inserts a material with self-lubricating properties "consist.

The innovation is explained in more detail below with reference to an embodiment shown in the "accompanying drawings explained.

In Fig. 1 is the side view of part of an innovation according to the invention Round steel chain shown in a position that the chain assumes when it runs over a sprocket. The chain "consists of horizontal members 11 and vertical members 12, which with the interposition of inserts 13 with each other are connected »The diameter of all round steel links is d. The inner width di has a value from 1.2 d.

in Fig. 1 denotes the wrap angle of the joint insert, while /) indicates the angular extent of the joint deflection. σ is the pitch angle of the toothed wheel, not shown, enclosed by the round steel chain. It depends on the number of teeth in the latter, and its value is equal to the quotient of 360 ° « the number of teeth.

The wrap anglept ', which is 180 ° - Θ or 180 ° - 2ß> , is selected so that the front edge 14 of the insert 13 is in no way moved over the line 15. on

This ensures that no wedge spaces are formed between the inserts 13 "and the chain links, into which dust can enter, which "in the return of the angled links could be promoted in the straight starting position between the support surfaces.

Fig. 2 is used to illustrate the shape of the inserts. As can be seen, each insert has two saddle surfaces 16 and 17 which cross each other and in terms of dimensions the limb curvatures are adapted., 18, 19 are the edges the end faces of the inserts, which must never stand out from the areas of the bends assigned to them «

The deposits can consist of suitable metals, E.g. made of bearing metal, sintered metal, bronze, etc. But plastics are also suitable as insert materials. In In any case, you should use additives that reduce wear, such as graphite or molybdenum sulfite
