Abstract
The utility model relates to an integral cast track shoe for a track tractor, comprising a plurality of pin holes, a guiding reinforcement, a plurality of pedrail aristae, a reinforcement, and a runway surface; wherein, six of eight pedrail aristae with the height of 50 to 65mm are symmetrically arrayed in a shape like a Chinese character ''eight''; the vertical distance between the centerlines of the upper pin hole and the lower pin hole is 170 plus or minus 2mm; the width of the outer margin of the track shoe is 440 plus or minus 2mm; the width of the inner margin is 390 plus or minus 2mm; the height of the pin holes and the runway surface is 23 plus or minus 2mm; the height of the guiding reinforcement is 58 to 65mm; the height of the pedrail aristae is 50 to 65mm; the diameter of each pin hole is 22 to 28mm; the pin hole on the upper part of the track shoe has four segments; the pin hole on the lower part of the track shoe has three segments; the reinforcement with the width of 6 to 7mm is arranged on the edge of the back of the track shoe; the diameter of each pin hole is 22 to 28mm. The utility model has the advantages of light weight, simple making, assembling and disassembling, low cost, and small power loss at high speed.
Description
(1) technical field
The utility model belongs to the trac. field, relates to a kind of crawler-tread tractor and casts caterpillar block with integral type.
(2) background technology
At present, domestic crawler-tread tractor is cast the patented product that caterpillar block is produced without competition for my company with integral type, the ZL992510511 patent documentation is put down in writing, and this integral type casting caterpillar block weight is lighter, and the manufacturing dismounting is also simple, cost is lower, the watt loss of running at high speed is little, but shortcoming is that the effective grounding area is little, and the coupling pin diameter is little, wearing and tearing are very fast, and service life is lower.
(3) summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, easy to use and reliable, suitably strengthens effective grounding area and coupling pin diameter, reduces wear, thereby improves crawler-tread tractor is cast caterpillar block with integral type life-span.
The technical solution of the utility model is: crawler-tread tractor is cast caterpillar block with integral type and is comprised the joint pin, pin-and-hole, guiding rib, reinforced rib, carry out thorn and runway face, it is characterized in that: the crawler belt grounded part is 8 and carries out thorn, wherein 6 shoe thorns are " eight " font symmetric offset spread, two the big thorns of carrying out in both sides are the arrangement of " one " font, track pitch A is 170 ± 2mm, the wide B of caterpillar block outer rim is 440 ± 2mm, the wide C of inner edge is 390 ± 2mm, pin-and-hole and runway face height D are 23 ± 2mm, the height E of pin-and-hole center and trapezoidal guiding rib is 58 ± 2mm, and track grouser height F is 50～65mm, and each pin-and-hole diameter Ф is 22～28mm, when crawler belt connect, the track pin head did not exceed outer rim.
The axis of described tilting shoe thorn length direction and the axis angle α of pin-and-hole are 20 ° ± 2 °.
When described guiding rib was arc, its height E was 65 ± 2mm.
The utility model can reach following beneficial effect: adopt the utility model integral type casting caterpillar block, crawler belt effective grounding area strengthens, and pin-and-hole adds the overstriking of ambassador's track pin, has strengthened antiwear property, has prolonged service life.
