Wear rule of track plate

When working normally, the crawler pin rotates slowly backward in the pin hole. Both wear evenly, the pin hole becomes larger gradually, and the pin becomes thinner gradually. If the operation is improper, such as turning at high speed, starting suddenly, or entering mud, weeds and so on to make the pin plug dead, will cause the track board on both sides of the pressure too heavy to sag, pin deformation bending, pin and pin hole can not rotate in the pin hole, pin and pin hole into sliding friction, and the friction part is limited to a small part of the contact surface, pin gradually grinding Turn the crank shape and the pin hole becomes ellipse. The enlargement of the pinhole leads to the elongation of the pitch of the caterpillar (pitch is the center distance of the holes at both ends of the caterpillar board), so the Caterpillar board and the driving wheel grind each other, the Caterpillar board is worn through, and the tooth of the driving wheel is like a knife edge. According to the measurement, when the pitch is changed from 174 mm to 184 mm, the opening width of the driving wheel teeth changes from 87 mm to 97 mm, and the normal rolling engagement is completely destroyed.

As the pitch of the track board is elongated, it also causes the support wheels to jump, accelerating the wear and tear of the track board. When the runway area is more than 4 mm, it should be repaired.

The wear and tear of the guide part of the caterpillar plate is mainly caused by the deviation of the caterpillar, the serious deformation of the caterpillar plate, and the axial sway of the supporting and guiding wheels.

The commonly used scrapped track boards are seriously worn out or worn through the engaging parts of the driving wheels.
