Track pin sleeve is an important connection of the combination track, it not only withstand the contact pressure stress
transmitted by the drive wheel teeth, but also to withstand severe abrasive wear, because the pin sleeve always works under the
condition of multiple shocks of small energy. According to the working characteristics of the pin sleeve, the material can be 20Mn
and 25MnTiBR heat treatment carburizing, one or two quenching at low temperature tempering, hardness is 58-62HRC, such as the use
of 60dt,T8 or T10 and other materials, after quenching and low temperature tempering life can be improved a lot!

Material Description
Integral track is on the track plate with meshing teeth, directly engaged with the drive wheel, the track plate itself becomes the
support wheel, etc. Integral track is on the track plate with meshing teeth, directly with the rolling track of the drive. The
track plate is connected with a pin shaft, and the pin is floating in the pin hole and has a gap of 0.5-1.5mm. This track is
generally used in large excavators. The advantage of this track is that it is convenient to manufacture and easy to disassemble
and assemble. The disadvantage is that dirt such as sand is easy to enter the pin hole, which speeds up the wear of parts and
affects the service life.

Material Description
The combined track is composed of a rail link, a track plate, a pin and a bushing. The rail link and track plate are bolted
together. The fit of the track pin and the bushing is 0.5-1.5mm interference tight fit, and the assembly should be carried out on
the press of more than 40t. In order to facilitate installation and disassembly, one of the controls can be converted into a
looser fit.
The advantages of the combined track are: the seal of the pin and the bushing is better, the dirt such as sand is not easy to
enter, because the hardness of the pin and the bushing is higher, the connection is more wear-resistant, so the service life is
also higher; Track pitch is small, good rotation, will not be due to track plate damage, bushing cracking or connection bolt cut
and stop the walking. In addition, the combined track parts have a high degree of universality, and the wearing parts are easy to
purchase, so the maintenance and replacement are convenient and the manufacturing cost is low. The disadvantage is that the
connection bolt is easy to break, and it is difficult to disassemble.
