What are the wear in the caterpillar drivers crawler
Track wear and tear on the dry track (
Relative to the lubrication type crawler and seal type caterpillar)
Walking mechanism of caterpillar no lubrication, cause in the process of work caused the crawler due to relative motion between pin and pin set of wear and tear.
Caterpillar pin and pin suites in the wear and tear is inevitable, is also normal, but the wear can make the track pitch of elongation, make the crawler is too large.
Wear this situation continues, caterpillar will generate lateral movement, leading to guide wheel, roller, sprocket, drive gear and other parts of wear and tear, at the same time has contributed more to the caterpillar pin and set of wear and tear.
Track wear is in contact with the ground for crawler plate and the reduction of track shoe thorn height and section for caterpillar caterpillar raceway surface and guide wheel, chain wheel, roller contact caterpillar caterpillar track section caused by the decrease of the height.
Crawler plate wear serious when will cause loss of bulldozer traction.
Guide wheel wear of guide wheel wear is due to contact the raceway surface of caterpillar track section, and the guide wheel body raised the width of the wear is due to come into contact with the side of the caterpillar track section.
Performance is: the guide wheel body raised width decreased;
The decrease of the raceway of the guide wheel body diameter;
The sprocket wheel wear of the sprocket wheel wear is the result of the raceway surface contact caterpillar track section.
Is shown as: the decrease of the supporting wheel flange width;
Joe sprocket raceway surface diameter decreased;
The decrease of the supporting wheel flange diameter.
The roller wear of roller wear as well as chain wheel, guide wheel wear, and the result of the raceway surface contact caterpillar track section.
Embodied in: the decrease of the outer flange diameter;
The decrease of the raceway surface diameter;
The decrease of the bilateral internal flange diameter;
The decrease of the flange width in bilateral;
The decrease of the outer flange width.
In view of the crawler walking mechanism of wear, can take the following measures: (
If travel mechanism bulldozer is apparent in the early stages of a wear, should immediately stop operation, check the guide wheel, chain wheel, roller, driving wheel center with the walking frame longitudinal center line of contact ratio;
In order to prolong service life, change the location of front and rear roller can be adjustable, but must keep single, bilateral roller in walking on the original position of the same;
After running gear parts wear to use limit, to guide wheel, chain wheel, roller, driving wheel tooth, fittingly, caterpillar welding can be used for repair or replacement;
For caterpillar caterpillar track pitch variable-length due to abrasion, can take reverse caterpillar track section to repair or replace new caterpillar track section.
