Understanding the Different Dozer Undercarriage Parts

Your dozer undercarriage is designed to support the weight of your machine and the forces of energy created when ripping or dozing equally across its surface area. Knowing and monitoring your dozer undercarriage is directly related to maintaining your machine availability and the availability is also a part of machine production.Get more news about Undercarriage Parts,you can vist our website!

Cat® undercarriage parts are made with high-quality materials and hence, are known for their durability. However, just like the other parts of your machine, you would need to maintain these undercarriage parts the right way to ensure a sustained level of performance. Since the path to proper maintenance begins with a primary understanding of the parts, we are here to spotlight some of the major dozer undercarriage parts.

The Basics

Undercarriage is a very delicate system, and designed to work in harmony with all the components of that system. Having one item fail, or misaligned can start to be seen in other areas of the system. Consistent wear across all undercarriage components helps to avoid premature failure and untimely expenses. Regular inspections and maintenance are the key to success.

Undercarriage life span, what shorten it and what helps?

Undercarriage, so tough and resilient, training your operators and your services team to recognize the undercarriage parts failures and choosing the right undercarriage parts for the application can go a long way in extending life, performance and getting a return on your investment, also will save money and increase equipment availability. Again understanding undercarriage system and regular inspections are the key to success.

Some Important Undercarriage information You Should Know About

Although there can be subtle differences in the design and configuration of parts depending on the manufacturer, here are some of those you’d mostly find in your dozer undercarriage.

Track links

The track links of the dozer are formed by a number of link sections, pin, seals and bushing linked together in different mechanisms with the help of flexible connections. In fact the track link is the most important components of the undercarriage as it represent 50% of the total undercarriage cost replacement. Something so simple you can do, will make a difference to your undercarriage:

Track link adjustment (not too tight not too loose): Track adjustment can have a very large effect on external bushing life, even to the extent of deciding whether a costly turn will or will not be required to use up the link-roller system. Track tension can also affect track seal integrity.
Keep your undercarriage clean: packing and mud and not cleaning your undercarriage out will certainly shorten your undercarriage life but make sure not to put high pressure water direct to the stopper in the link, then the oil will leak.
Avoid unproductive high speed your undercarriage will thank you! Unproductive high speed, reduces life and increases costs. Example: Using high speed reverse when there is cycle time available. If the machine is pushing scrapers and there is sufficient time for the machine to back up in first gear between finishing the first scraper and waiting for the second to arrive but the operator is using 3rd group.

Slewing Bearing Environment

The slewing ring working temperature is normally from -300C to +700C. If the user needs to adapt to the lower or higher temperature slewing bearing, our company can carry out special design. Slewing bearings can be used in particularly harsh slewing bearing environment such as maritime climate, dust or abrasive particles, sand, cement, coal powder, etc. Special seals, guards, and suitable oil passages must be used. Therefore, in order to make your support work properly, you want to do daily maintenance and maintenance work.Get more news about Swing Bearing,you can vist our website!

For slewing bearing environment, the mounting surface should be smooth and clean, removing all superfluous material such as paint residue, welding beads, burrs, etc.Care should be taken not to let the solvent infiltrate into the rotary support during cleaning. Do not use solvents that damage sealing materials.The mounting surface should be dry and free of lubricant before assembly.Measures should be taken to protect workers and the environment.

In order to avoid partial overload of rotating support caused by unevenness of mounting plane or bearing deformation, the circumferential flatness error can only be undulated once within any 180 degree range, and the change is gentle.

The difference between slewing bearing and ordinary bearing

1. The installation method is different. The slewing bearing is not sleeved on the mandrel and installed in the bearing box like an ordinary bearing, but is fixed on the upper and lower supports by screws.Get more news about Swing Bearing,you can vist our website!

2. Generally, the slewing bearing must bear several loads, not only the axial force and radial force, but also the large overturning moment. Therefore, a set of slewing bearings often plays the role of several sets of ordinary rolling bearings.

3. The running speed of the slewing bearing is low, usually below 50 rpm. In many cases, the slewing bearing does not operate continuously, but only rotates back and forth within an angle, which is equivalent to the so-called "swing bearing".

4. The size of the slewing bearing is large, and its diameter is usually 0.4-10 meters, and some are as large as 40 meters.

5. Generally, the slewing bearing is provided with a ring gear for rotational driving and a sealing device for dust prevention.

6. In terms of materials and heat treatment manufacturing processes, slewing bearings and rolling bearings are very different.
