Although tribology is a fringe discipline, it studies a wide range of objects.

In mechanical engineering, it mainly includes dynamic and static friction, such as sliding bearings, gear drives, tape recording heads, etc.; elastomeric friction, such as friction between automobile tires and road surfaces, power leakage of elastic seals, etc.; tribological problems under special working conditions, such as high vacuum, low temperature and ion radiation encountered in cosmic exploration, high pressure, corrosion, lubricant dilution and leak-proof seals for deep sea operations and other applications.

Lubrication is a whole branch of tribology used to study the reduction of friction. For example, common measures include the use of lubricants on relatively sliding surfaces, or balls to make sliding change to rolling.

However, over time, there is a process of wear and tear between the movements of machinery, which causes lubrication to lose its effect and leads to wear of mechanical parts. This not only affects the overall operating performance of the machine, but also raises maintenance costs, and in some cases, even noise can occur. As in life, there are noisy dryers, car seats to push the strain, etc.

A small part is enough to change the friction between two surfaces. This approach comes from the self-lubricating PTFE bushing solution.

A low friction layer (i.e., boundary friction) is created by laminating a PTFE film on the bushing; in some cases, a thicker PTFE film can completely separate the two surfaces.

Tribology Solutions Tribology Solutions：Supplier of sliding bearings, metal-polymer bearings. We have been deeply involved in the field of tribology, and in addition to sliding bearings – which have so far been developed in metallic polymers, reinforced fibers and engineering plastics – we have also created a new tribological design solution in the form of shape-independent coatings.

Tribology is the science of wear, friction and lubrication and covers the behavior of interacting surfaces and other friction elements during relative motion in natural and artificial systems. Tribological systems analysis is the basis for understanding the effects of friction factors.

For long-term, trouble-free operation of mechanical components, all influencing factors must be considered during the design process. A mechanical design component will only operate efficiently and have an optimal service life if all of its components work closely together and function well.

Bearings are one of the most critical components in a rotary or linear motion mechanism. Engineers must consider factors such as bearing type, size, speed and load. One of the most often overlooked important factors in bearing design is friction. In fact, friction should be taken into account at the beginning of design, which can improve the efficiency and service life of frictional contact and thus design surface engineering solutions beyond the traditional ones.

Dry Friction Bearing Bushing

The surfaces used in dry friction bearings are solid surfaces that come into contact with the bearing and generate wear during relative motion. One of these surfaces is softer than the other, and the softer surface is usually the bearing surface because it is cheaper to replace a worn bearing than to replace a shaft. In addition, bearing materials used for dry friction contact usually perform better when used in conjunction with relatively hard relative surfaces.

The shaft surface finishing process is a critical factor in the performance of dry friction bearing contacts. Although the size of the profile is only a few microns, its effect on bearing performance must also be considered.

Wear and Friction Bushing

The formation of a transfer film on the surface of the counterpart is an important feature of all dry friction bearing materials. This protective film reduces wear by filling in the raised roughness peaks and valleys.

Transfer films are formed by wear debris from the bearing material. They are very thin structures, approximately thinner than a human hair.

Transfer films and wear behavior

For polymer composites, wear caused by abrasive particles is the dominant wear mode. Increased wear is the result of missing or inadequate formation of transfer films, which cover the dyadic surfaces and reduce abrasive wear on the opposing dyadic surfaces, thus improving wear performance.

Rough opposing surfaces produce only a small amount of wear debris, and no transfer film is produced on the steel surface. This demonstrates that the lack of transfer film is a key factor in high wear and that rough opposing surfaces are less susceptible to transfer film formation.

How can tribology be applied to the formulation of lubricants? It depends on the efficiency of the lubricant, which depends on the viscosity, and finding a balance between reducing sliding friction and too much viscosity.

Often, in sliding surfaces, energy is reduced by friction, so energy consumption is reduced by ensuring that the system has low friction. The study predicts that only 21.5% of the fuel energy powers the car, while friction losses account for 33% (28% if brakes are not counted).

The highly functional plastic self-lubricating PTFE bushing solution is an effective application of combining tribological research with materials science.

How can tribology be effectively applied? Self-lubricating bearings, by producing reliable, excellent and durable products, help control and reduce wear of mechanical products, automotive, aerospace, electronic equipment, robotic arms, etc., save weight and space required for manufacturing parts, and to some extent reduce wear, noise, vibration, and high corrosion.

At the same time, self-lubricating bearings create low friction to try to reduce useless friction consumption, thus saving a lot of energy, improve life and reduce maintenance costs.
