Definitions
- a chain lock of the above type is known from DE 32 07 629 C2 with regard to its basic structure.
- the known chain lock is characterized by a favorable distribution of the forces to be transmitted to the different pairs of retaining teeth. Regardless of its advantageous design, the strength values that can be achieved with the known lock are still noticeably smaller than the strength values that the links of the chain strands to be connected have. In order to approximate the strength values of the lock to the strength values of chain links of the same quality class, different approaches were taken.
- the object is achieved in that the holding teeth of the middle pairs of holding teeth and the holding teeth of the pairs of holding teeth arranged in the region of the ends of the inner legs have a greater height than the holding teeth of the pairs of holding teeth arranged in the region of the ends of the outer legs and that between the flanks of the respective Interlocking half-teeth of each pair of retaining teeth are provided on both sides of a central support zone which extends at most over a third of the height of the retaining teeth and is used to transmit tensile forces.
- the proposed height ratios ensure that wear of the outer legs of the lock leads to a weakening of the lock strength less quickly than previously.
- the design of the contact conditions between the flanks of the holding teeth results in a more favorable stress distribution in the castle and this in particular in the case of heavy loads.
- L is a top view of a chain lock
- 2 shows the side view of the chain lock according to FIG. 1
- Fig. 3 shows a section along the line III -III in Fig. 1 and
- Fig. 1, 1 and 2 are two identically shaped, substantially U-shaped lock parts, each of which has an outer leg 3 and an inner leg 4.
- the outer legs have three holding teeth 5, 6 and 7 and the inner legs have three holding teeth 8, 9 and 10.
- the height H of the holding teeth 5, 6, 8, 9 is greater than the height h of the holding teeth 7, 10.
- the surfaces of the outer legs 3 facing the inner legs 4 are concave and the surfaces of the inner legs 4 facing the outer legs 3 are convex.
- Fig. 4 the investment relationships between the holding teeth 6 and 9 are shown on an enlarged scale. It can be seen that the tooth flanks 15, 16 rest against one another only along a support zone 19 located between the small circles 17, 18 shown in FIG. 4. Cavities 20, 21 are arranged on both sides of the support zone 19. The design of the tooth flanks 15, 16 described guarantees that tensile forces introduced into the chain lock are transmitted at a precisely defined, favorable point. In the area of the transitions of the tooth flanks 15, 16 into the respective tooth base 22 or 23, a series of dents 24, which overlap slightly on the sides and are indicated by dashed lines, are arranged.
- the dents 24 are produced by pressing a tool with a dome designed as a pressure stamp into the tooth base.
- the plastic deformation of the tooth base in the area of the dents 24 leads to the build-up of permanent compressive stresses.
- the normal tensile stresses arising due to the external forces must first overcome these compressive stresses before they reach an extent that can lead to harmful cracking.
- the plastic deformation of the tooth base considerably increases the dynamic strength of the chain lock.
- the dents 24 preferably have the negative shape of a section of an ellipsoid, the semiaxes of which can be the same in the case of a spherical tool.
- pyramid, truncated pyramid, truncated or truncated cone-shaped printing tools can also be used for producing the dimples 24.
- the depth t the impressions formed by the dents 24 should be at least 2% and at most 20% of the radius R in the region of the transition of the tooth flanks into the tooth base and the smallest distance between the centers of neighboring dents should be in the order of 5 to 15% of this radius R.
