One drilling, and another carrier bar in the two carrier bars has the second drilling with the sliding fit in connecting element.It is respective
There are two the end sections of distal end for connecting element tool, wherein carrier bar there are two being arranged axially adjacent in each end section.
The present invention includes following technical teaching: respective connecting element is respectively by the carrier bar with two inside of two outsides
It is connected with each other, wherein or the carrier bar of two outsides has the press-fit in connecting element, and the carrier bar tool of two inside
There is the carrier bar of the sliding fit or two inside in connecting element that there is the press-fit in connecting element, and two outer
The carrier bar in portion has the sliding fit in connecting element.
Advantageously, external or internal carrier bar at least has the label for simplifying assembly.For " label " should be understood that
The carrier bar for being used to assemble such as is expressed as external or internal carrier bar in a manner of visible.Label for example can be by laser reality
It realizes now or mechanically.Especially it is contemplated that the asymmetrical outer profile on external or internal carrier bar is for being marked
Know.Other recess portion is introduced as label in addition it is also possible to be arranged.It is also contemplated that marking all carrier bars, wherein external
It is different from each other with the label of internal carrier bar.
Preferably, respective connecting element is configured to latching.Alternatively, respective connecting element is configured to sleeve.Therefore,
Carrier bar is connected with each other either by latching or by sleeve.It is achieved in weight savings.
Present invention relates especially to the chain gearings with chain according to the present invention for oil pump.Alternatively,
Chain according to the present invention also can be used in other chain gearings.
