二,Overview of Excavator Track Bolts
2.1 Structure and Working Principle
2.1.1 Component Structure of Track Bolts
An excavator track bolt is composed of several key components, each
playing a distinct and crucial role in ensuring the connection and
stability of the track system.
The screw rod is the main body of the track bolt, usually with a cylindrical
shape. It is threaded along its length, and these threads are the
key elements for engaging with the nut. The diameter and length of
the screw rod are designed according to the specific requirements
of the excavator model and the load - bearing capacity needed. For
example, in large - scale mining excavators that operate under
extremely heavy loads, the screw rods of track bolts are often
thicker and longer to withstand the large - scale pulling and
shearing forces generated during the digging and transportation of
ore. The material of the screw rod is typically high - strength
steel, which can provide sufficient strength and toughness to
resist deformation and breakage under various working conditions.
The nut is another essential part. It has internal threads that match the
external threads of the screw rod. When the nut is tightened onto
the screw rod, it creates a clamping force that holds the connected
components together. Nuts used in excavator track bolts are often
designed with a hexagonal shape, which allows for easy operation
with common wrenches. In some high - performance excavators, self -
locking nuts may be used. These self - locking nuts have special
structures, such as nylon inserts or deformed threads, which can
prevent the nut from loosening due to vibration and dynamic loads
during the excavator's operation.
Washers are also an important part of the track bolt assembly. There are
two main types of washers: flat washers and spring washers. Flat
washers are placed between the nut and the surface of the connected
component. Their function is to distribute the clamping force
evenly over a larger area, preventing the surface of the component
from being damaged by the concentrated force of the nut. In
addition, flat washers can also help to fill any irregularities in
the surface of the connected component, ensuring a more stable
connection. Spring washers, on the other hand, are designed to
provide an additional anti - loosening function. They are made of
spring - like materials and have a split - ring shape. When the nut
is tightened, the spring washer is compressed, generating a
resilient force that helps to maintain the tightness of the nut -
bolt connection. In the harsh working environment of excavators,
where there is continuous vibration and impact, spring washers play
a crucial role in preventing the track bolts from loosening.
