の加工が複雑で多大の工数を要する欠点がある。 To join the ends of a conventional track chain,
Either a track pin is force-fitted into the master link to couple it, or split link halves having mating surfaces that align with each other are connected to both ends of the track chain, and a large number of tooth-shaped uneven parts are formed on the joining surfaces. A structure is used in which the two split link halves are bolted together with the show plate in a state in which they are tightly meshed with each other. However, the former structure requires a lot of effort and time to press-fit the pin, and it is difficult to attach and detach at the site of use. However, the machining of the uneven portions is complicated and requires a large number of man-hours.

In Figures 3 to 3, the split link halves 3 and 4 having the pin hole 1 and the bushing hole 2 are a single serrated joint with unevenness formed vertically along the center line 5 connecting the centers of both holes 1 and 2 in the connected state. Joined by surface 6. The joint surface 6 has a vertical cut surface 7 that is perpendicular to the center line 5 between the holes 1 and 2, and an upper surface 8 and a lower surface 9 of the split link half that are connected to the hole 2 of the other half of the split link.
or a point a reaching above or below almost inside of 1;
It has inclined cutting surfaces 10 and 11 extending from b to the cutting surface 7 at an acute angle beyond the center line 5. The triangular head formed by the cut surfaces 7 and 10 is cut off in the direction of the center line 5 to form a trapezoidal protrusion 12 on the split link half piece 3, and the protrusion 12 is similarly formed on the split link half piece 4. A gap 14 is provided in the trapezoidal recess 13 for close engagement, and the cut surfaces 7 and 11 are formed on the split link half piece 4.
A trapezoidal protrusion 15 formed as a side in the same manner as described above is tightly engaged with a trapezoidal recess 16 formed in the split link half piece 3 with a gap 17 provided therebetween.

を与えるに役立つ。 The cutting surface 7 extends equally long above and below the center line 5, has a length sufficient to support the maximum tension of the track chain with an appropriate surface pressure, and has a sufficient length to support the recesses 13, 16 of the split link halves 3, 4. The cross-sectional dimensions of the portion provided with the recesses 13 and 16 were determined to sufficiently withstand the complex external forces applied to the split link, and in order to avoid concentration of stress in the portion provided with the recesses 13 and 16, the recesses 13 and 1
Add an appropriate roundness to the inner corner of 6. Cut surface 10,1
1 serves to provide appropriate strength to the protrusions 12 and 15 against the external force.

Two bolt holes 18 passing through the protrusions 12 and 15 from the side of the split link half piece 4 and screw holes 19 are provided in the split link half piece 3 at the tip thereof, and the split link half pieces 3 and 4 are attached to the bolts 21 together with the show plate 20. The agreement will be concluded.

分に対抗することができる。 The split link halves 3 and 4 are tightly joined at the joint surface 6 by the above-mentioned fastening, but due to the complicated external force, the protrusions 12 and 15 are forced to close the holes 1 and 2 within the range of manufacturing accuracy and elastic deformation of the component parts. Relative rotation in opposite directions about the center is expected. However, even in this case, when the track chain is in a tensioned state with surface pressure acting on the cut surface 7, the center portion of the cut surface 7 of the protrusions 12 and 15 interferes with the corner portions c and d at both ends, and the relative rotation is prevented. Ru. This blocking effect becomes stronger as the tension of the track chain increases. Even if the relative rotation occurs slightly due to the elastic expansion of the bolt 21 and the wear of the cut surface 7, for example, at the initial stage of rotation, the protrusion The contact pressure between the tip of the protrusion 12 and the base of the protrusion 15 generates a moment that prevents the relative rotation. Therefore, according to the present invention, the tension of the track chain as well as the relative rotation of the split link halves 3, 4 can be sufficiently counteracted by one cut surface 7.

ラツクチエーンの修理、交換も可能である。 As shown in FIG. 4, a pair of left and right split link halves 3, 4 are connected to both ends of the track chain 21 by a pin 18 and a bush 19, both ends of which are press-fitted into the pin hole 1 and the bush hole 2. When a track chain connected in this way is installed on a civil engineering machine, etc., the chain is in a non-tensioned state and there is usually some play between the chain and the sprocket. After rotating around the pin and bush, the protrusions 12,1
5 can be easily moved in the direction of the cutting surface 7 and engaged in the recesses 13 and 16, and the track chain can also be easily removed, making it possible to repair or replace the track chain at the site of use.
