Self-lubricating bearings repair bushing solutions

Rolling bearing is a kind of rolling bearing, which is based on high quality cold-rolled steel plate and sintered with porous spherical bronze powder in the middle, and then sintered with a mixture of PTFE and fiber on the surface of porous spherical bronze powder, and rolled.
This product has the characteristics of small friction coefficient, abrasion resistance, good corrosion resistance and self-lubrication.Using this product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of shaft biting and reduce the mechanical noise and other characteristics.
This product has been widely used in various mechanical sliding parts, such as printing machine, elevator, textile machine, tobacco machine, fitness machine, hydraulic conveyor, micro-motor, solenoid valve, automobile and agricultural and forestry machinery.

Metal Polymer Composites Plain Bearing

Self-lubricating bearing, moving it against the clutch diaphragm spring fingers. ... Dual-Mass Flywheel prevent engine torque spikes from exceeding engine and ... self-adjusting cable systems, are in constant contact with the diaphragm spring fingers.

self-lubricating materials meeting RoHs environmental requirement in automobile field. Oilless bearings are installed at over 30 parts of an automobile, such as door hinge, engine hood hinge, trunk hinge, windscreen wiper, shock absorber, steering system, pedal assembly, seat angle regulator and starting motor.

Self-lubricating bearing widely use in dual-mass flywheel.

A dual-mass flywheel is a rotating mechanical device that is used to provide continuous energy in systems where the energy source is not continuous, the same way as a conventional flywheel acts, but damping any violent variation of torque or revolutions that could cause an unwanted vibration. The vibration reduction is achieved by accumulating stored energy in the two flywheel half masses over a period of time but damped by a series of strong springs, doing that at a rate that is compatible with the energy source, and then releasing that energy at a much higher rate over a relatively short time.

Double mass flywheel like hamburger?

Double mass flywheel structure is very simple, the first mass flywheel and engine crankshaft output flange connected, the second mass flywheel through a self-ubricating bearing mounted on the first mass flywheel, the second mass flywheel with clutch cover.There is a shock absorber connection between the two flywheels.
 

• ROLLED DRY SLIDING BEARINGS (PTFE)

• Steel + Bronze Powder + PTFE/Fibre(DU)

• Wrapped PTFE Lined (maintenance-free), self lubricated plain or flanged bearings, thrust washer and strip, Carbon steel shell with sintered bronze layer filled with PTFE

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.

 
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.

The main factors affecting the life of self - lubricating bearings

1: load P: the greater the load, the shorter the service life of the bearing;Under no circumstances shall the maximum load exceed the theoretical maximum allowable load.
2: speed V: the higher the speed, the shorter the service life of the bearing;Under no circumstances shall the maximum sliding speed exceed the theoretical maximum allowable value.
3: PV value: the working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller PV value is, the longer the bearing life is.
4: temperature: the life of the bearing also depends on the temperature when the bearing is in use, the higher the temperature, the shorter the life of the bearing, so in the design and selection should try to consider the heat dissipation characteristics of the relevant parts.
5: surface roughness of the grinding parts: alloy steel or hard chromium plated shaft is used for the grinding parts. When the surface roughness Ra=0.4-0.63, the service life of the bearing can be significantly improved.
6: other factors such as bearing design, lubrication conditions, etc
