Definitions
- the invention relates to a chain lock for round steel chains according to the features in the preamble of the protection claim. 1
- the invention has for its object to show a chain lock for round steel chains, which is more resilient and in particular better prevents shearing of the lock halves under load.
- the invention is achieved by a chain lock with the features of the protection claim 1.
- the chain lock according to the invention for round steel chains has two lock halves, each having a extending in the longitudinal direction of the chain lock spine portion and end side adjoining dome sections, each one of the dome sections has a transversely projecting to a dividing plane of the chain lock locking pin.
- the locking pin has on its side facing the other dome portion at its free end a web-like, extending from side surface to side surface of the lock half, a bag delimiting projection, wherein the pocket for receiving a matched to the contour of the pocket fork web of the other Lock half is provided.
- the pocket has outer, essentially rectilinear flanks facing the side surfaces. points, wherein the angle enclosed by the flanks is in a range of 120 ° to 150 °.
- the inventive design of the locking pin due to their ability to absorb high lateral forces allows to relocate the mutual locking means of a clamping pin in a center support between the back portions of the lock halves.
- This eliminates the previously required transverse holes in the end-side dome sections and thus eliminates the local inhomogeneities caused by the holes in the voltage curve, since the inhomogeneities can ultimately lead to voltage spikes and earlier failure of the lock halves.
- the shear stresses applied by the damaged round steel chain are lower, so that with a suitable dimensioning a single bore with a locking pin can be sufficient.
- a center support has a groove running in the longitudinal direction of the chain lock and the other center support has a spring fitting in the groove, wherein the tongue and groove are penetrated by at least one transverse bore for receiving a locking pin.
- tongue and groove in the center support could also be configured as a single-leg, so that only two centrally projecting tabs are penetrated by a locking pin.
- the lock halves during the forging are still symmetrical parts, the asymmetry arises only later by machining. The imbalance is exclusively due to the configuration of the center support. Apart from the design of the center support, the halves of the lock are otherwise identically configured.
- the engaging in the pocket fork web has the flanks facing engagement surfaces which enclose the same angle as the flanks of the bag. Due to this matching contour of the pocket and the fork web, the overlap in the transverse direction is maximum, which improves the load capacity of the chain lock.
- flanks of the pocket and the engagement surfaces of the fork web do not touch each other when the lock halves are coupled with one another but are arranged with play relative to one another. This means that over the locking pin and the pocket normally no longitudinal forces applied by the chain are transmitted.
- the locking pin is solely for the absorption of shear forces, the z. B. induced by the introduced longitudinal forces.
- the dome portion carrying the locking pin has a receptacle for the positive integration of a cam of the other lock half adapted to the receptacle, wherein longitudinal forces acting on the chain lock can be introduced via the cams and receptacles into the respective other half of the lock.
- the recordings and cams are therefore in the range of the main tensile direction, that is in the region of the dividing plane of the chain lock. It is advantageous if the main extension axes of the receptacles and cams are at an angle to the median transverse plane of the chain lock.
- the angle between the main extension axis of the central transverse plane is dimensioned so small that the desired low axial relative displacement of the lock halves during assembly and disassembly of a block lock only is slightly increased. A sliding of the mutually contacting surfaces of the cams and recordings is avoided by the inclination of the cams and receptacles relative to the median transverse plane of the lock halves.
- Figure 1 is a chain lock in the assembled state
- Figure 2 shows a section through the chain lock of Figure 1 along the
- FIG. 3 is a side view of the lower chain lock in FIG. 1;
- FIG. 4 shows the block lock of FIG. 3 looking in the direction of its back section
- FIG. 5 shows the block lock of FIG. 3 in the direction of view from above
- FIG. 6 shows the upper block lock in the image plane of FIG. 1 in the side view:
- Figure 7 shows the block lock of Figure 6 in plan view
- FIG. 1 shows a chain lock 1 with two substantially L-shaped configured lock halves 2, 3, each one in the longitudinal direction, that is in the direction of its division plane TE-TE extending back sections 4, 5 and the end adjacent thereto dome sections 6, 7, 8, 9 have.
- FIG. 1 shows the sectional view along the line AA, that is, along the median transverse plane MQE of the chain lock 1, wherein a spring 12 of the upper half of the image in the image plane 2 in a groove 13 on the center support 11 of lower lock half 3 attacks.
- a transverse bore 14 is arranged, in which a locking pin 15 can be used in the form of a clamping pin.
- FIG. 3 shows in a representation of the lower lock half 3 that the dome section 6 on the right in the image plane is divided into two height ranges .
- a locking pin 16 arranged above the dividing plane TE is to be mentioned, which extends transversely to the dividing plane TE of the chain lock 1 upwards, so that each half of the lock 2, 3 is to some extent L-shaped.
- the locking pin 16 is part of an end-side end face 17 of the dome portion 6, with its free end 18 extends into the plane of the back surface 19 of the back portion 4 of the other lock half 2. According to the contour of the chain links to be connected and the end faces 17 of the chain lock 1 are rounded.
- the locking pin 16 has at its free end 18 a web-like projection 22 extending from the side face 20 to the side face 21 (see FIGS. 4 and 5) of the chain lock 1, so that a pocket 23 is delimited below the projection 22.
- the pocket 23 is shown in FIG. 5 with a broken line.
- To the dome section 6 also includes a receptacle 24, which serves for the positive inclusion of an adapted to the receptacle 24 cam 25 of the other half of the castle.
- the receptacle 24 and the cam 25 serve to transmit in the longitudinal direction, that is, in the direction of the division plane TE of the chain lock 1 acting forces.
- the main extension axis HA of the receptacle 24 or the main extension axis HN of the cam with the central transverse plane encloses an angle W which lies in a range of 3 ° to 7 ° (FIG. 3).
- the locking pin 16 with the projection 22 and the pocket 23 formed thereby lies outside the main load direction, that is, outside the dividing plane TE, and serves primarily to absorb transverse forces acting transversely to the dividing plane TE.
- the lateral forces are received by the projection 22 and a matched to the pocket 23 fork web 26th
- the projection 22 has over its entire extent a constant width B. Accordingly, it is provided with a larger radius than the transition region between the flanks 27, 28.
- the flanks of the projection are characterized in the angle W1 to each other, the angle W1 between the Flanks of the pocket 23 corresponds ( Figure 5).
- the width B of the protrusion 22 is dimensioned such that a cam 25 can be guided obliquely past the front side of the protrusion 22 while maintaining the angle W (FIG. 3), so that the cam 25 in the assembly position has its outer edge 31 below the protrusion 22 is placed. That is, the projection 22 extends not only beyond the pocket 23, but also beyond the lowest point of the receptacle 24, as can be seen from the figure 5.
- FIG. 4 shows that a bulge 32 is formed in the back surface 19 of the lock half 3 in the region of the fork web 26.
- a mandrel can be attached to the lock halves 2, 3, so that blows can be exerted on the locking pin 16 via the dome in order to separate the lock halves 2, 3 from one another.
- the hatched areas in FIG. 7 on the one hand show a partial section through the locking pin 16 in the area of the pocket 23 and on the other hand in the left-hand image area a partial section through the receptacle 35, which serves for the integration of a chain link.
