Problems solved by technology

Disadvantages, however, are high manufacturing costs and the fact that a further component is required for the steel ball, thereby increasing the variety of parts
The chain link disclosed in DE 196 52 262 C2 also has the disadvantage that a separate locking element is used instead of the locking ball

Abstract

The invention relates to a chain connecting link, which has two link brackets (4, 5) coupled via their limbs (6, 9), and a bar (14a-14c) that is inserted transversely between the limbs (6, 9) of the link brackets (4, 5). One limb (6) of each link bracket (4, 5) comprises a neck section (7) and a journal (8) thicker than the neck section, and a neck recess (10) and a journal recess (11) are provided in a matching fashion at the other limb (9) of the link bracket (4, 5). According to the invention, conically configured flank surfaces (12) with respect to the vertical central longitudinal plane (MLE) are provided at each journal (8) and at each journal recess (11).

Description

technical field The invention relates to a chain connecting link according to the features of the preamble of claim 1 . Background technique Chain connecting links are used in particular in high-power round steel chains such as are used in underground mining. It is known that, in the case of chain link links of inclined construction, dismantling after use may be more difficult, because the long clamping pins are rusted in the link plane through the arms and ribs of the two half-links facing each other. Inside the hole extending obliquely. In addition, the clamping pin is subjected to shear stresses, like the ribs arranged between the half-links, due to the loading of the chain connecting the two half-links of the chain link, which additionally increases the difficulty of pulling the clamping pin out of the elongated hole. In addition, a long punch is required to knock out the clamping pin, which is subjected to great bending stresses during the knocking out process, which ...
