Product Description

Air conditioner compressor bearing Metal-polymer Bushings for Compressor Applications assembly clearance range

The metal-polymer composite bearings developed by VIIPLUS have unique advantages over lead-bearing bronze or bimetallic bushings because of their self-lubricity so that contact between mating surfaces does not result in high wear or friction.Therefore, metal polymer composite bearings can provide a more reliable solution.

1.The system design


In most applications, the design of the bearing system is primarily affected by or between the shaft and the bearing surface.For compressor, clearance is an important factor affecting efficiency.The results of many years' research show that the efficiency of metal-polymer composite bearings in an effective clearance range increases more than the expected range of bimetal bearings.Since the installation tolerance range of metal polymer composite bearing is relatively large, whether it can effectively maintain or improve the efficiency will test the design strength and manufacturing strength of bearing manufacturers.And that's where VIIPLUS engineers are going.


2.performance


The performance of the compressor's metal-polymer composite bearing depends not only on the clearance, but also on the ability of the material to withstand various speeds, loads, temperatures and corrosion effects under these application conditions.Typical bearing failure modes of compressor include wear, fatigue and corrosion.By incorporating (PTFE+ filler material) into the steel back, VIIPLUS's metal-polymer composite bearings are resistant to wear and fatigue and, in most cases, superior to conventional compressor bearings.


In addition, the formation of lubrication film and other important factors in bearing design are determined according to the conventional fluid dynamics calculation in journal bearings.In some cases, metal-polymer composite bearings show a unique phenomenon: the modulus of the bearing surface is actually lower than that of bronze, bimetal or steel.Higher loads result in greater film thickness under elastohydrodynamic lubrication (EHL) conditions than conventional journal bearings under the same conditions.Experts generally agree that polymer surface compliance can more effectively distribute load and increase film thickness.Moreover, even in the case of poor film formation, the metal-polymer composite bearing still has certain advantages because of its lubricated PFTE surface.


Finally, if properly designed, the metal-polymer composite bearing system will be more reliable than conventional bearings.PTFE is a natural lubricant that can achieve higher heat and wear resistance under edge and boundary lubrication conditions.PTFE+ polymer has higher surface compliance and better ability to cope with shaft deflection than traditional compressor bearings, thus making the system more suitable for the superposition of tolerances in compressor design.Moreover, metal polymer composite bearings can better adapt to environmental requirements to minimize environmental pollution and reduce the overall compressor cost from the overall environment.
Through the above elaboration, it can be seen that a small bearing parts can have so much impact on the service life of the overall air conditioning.We enjoy the cool behind the original so many people's wisdom and sweat, you are using the air conditioner may be VIIPLUS bearing behind the silent pay!

 

Typical Applications

 

At present, most air conditioners produced in China use screw compressor, which must meet the following conditions: high compression efficiency, few parts, small volume, light weight, low noise, low power consumption and low overall cost.In order to meet these body conditions, for the compressor in each spare parts requirements that is more stringent.High requirements for materials, processing accuracy, heat treatment, assembly process and lubrication system.

Many screw compressors currently use lead-bearing bronze or bimetallic bushings whose performance and reliability are largely dependent on lubrication conditions.If not provided with good lubrication conditions, mixed film and boundary lubrication conditions that will lead to contact between mating surfaces can produce higher friction and excessive wear.In addition, many lead-containing bronze materials are not conducive to environmental protection based on the improvement of environmental protection requirements of major air conditioning manufacturers.In view of the above situation, VIIPLUS engineers have developed a metal polymer composite bearing solution from the aspects of materials, system design and performance.

 

Metal-polymers Bushing have achieved commercial application in compressor design by system design adjustment and/or finishing operation control,Traditional compressor bearings such as rolling element bearings, lead-bearing bronze or bimetallic bushings are greatly affected by wear in the absence of lubrication at the bearing position.metal polymer Self-lubricated bushings making them a more reliable solution under such special conditions.In addition, compared with other journal bearings, they have other advantages such as lead free, low noise and low friction.Compared with traditional bearings, assembly clearance range is one of the biggest obstacles in metal polymer design, because it can directly affect the working efficiency.

Self-lubricating bearings High speed high load compressor solution

High speed high load compressor self-lubricating bearing solution, variable speed machine and air conditioning compressor from rolling bearings to self-lubricating bearings, replacement rate of 80%.
If the world's rolling bearings are replaced by self-lubricating bearings, the market space?

Design high speed high load compressor, without increasing the cost, to ensure that the performance of continuous improvement, you are ready?

 

VIIPLUS not only provides simple self-lubricating bearing and sliding bearing materials, but also finds problems, solves problems, finds the most suitable product matching solution, and prolongs the service life of the compressor and provides the performance of the compressor in application.

Construction machinery manufacturers have been troubled by severe operating environment and high regular maintenance costs.VIIPLUS USES a self-lubricating maintenance-free design that reduces the cost of bearings and systems while avoiding potential application risks.This not only saves the cost of bearing and the system itself, but also reduces the later maintenance cost.

Characteristics


VSB-10 Self-Lubricating Multilayer Composite Bushing
· Bushing material suitable for lubricated applications
· self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Anti-friction bearing suitable for linear, oscillating and rotating movements
Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.


Strusture


1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.

 
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.


3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
