The knowledge of Slide Bearing, Sliding Bearing
The slide bearing, functioning under sliding friction, functions reliably,
smoothly and quiet.
If slide bearings lubricated with liquid, the sliding
surface won't contact with other directly and it may decrease the friction and
surface abrasion. The oil slick also affords the skills of absorbing vibrations
nevertheless friction resistance.
The part that is supported by the bearing is known as the journal also, the part matched with it is recognized as
the bearing bush. To be able to enhance the friction on the surface of bearing
bush, relating to the inner surface of bush, a material layer with regard to
decreasing friction was cast, that is known for the reason that bearing
linear.
The material for producing the bearing bush along with the bearing layer are termed with a joint name of sliding bearing product. The
sliding bearing is actually primarily utilized under the condition of low speed
and excessive load or used inside running parts which are difficult to become
maintained and lubricated.
The Classification of Sliding Bearing
according to the direction where the download is applied, it could be classified
into the thrust sliding bearing and also the radial sliding bearing. This Thrust
Sliding Bearing: The direction of their total load is paralleled while using the
crucial line of shaft. The Radial Sliding Bearing: The direction of their load
is vertical to the central line of shaft.
According to the distinctive
shaping manner of the lubrication slick, this could be classified into the
hydrodynamic sliding bearing along with the aerodynamic bearing. The
hydrodynamic sliding bearing: Due to the geometry shape along with the relative
motion in relating to the vice-surfaces of relative motion and also by the
assist involving viscosity of fluid, the lubricant could be injected on the
friction surface and the motion vice-surfaces may be separated via the natural
fluid film, that is known as the hydrodynamic lubrication. This aerodynamic
bearing: Inject the high-pressure lubricant on the surfaces in between the
sliding bearing additionally, the axle journal to transport the outside load and
separate the motion vice-surfaces, which is sometimes called aerodynamic
lubrication.
If move bearing lubricated with water, the friction could
end up decreased significantly. As the sliding showing is of wonderful friction
loss and low efficiency and it actually is difficult to maintain in a large
amount working parts, for example the slicer approach, the motor vehicle while
using reduction gear box, choosing taken location by your rolling
bearing.
However it still executes a significant part in lots of special
conditions.
1 In accordance with the assembly requirement, it's been
consisting of the mode of quarter-cut: The crank axle of the starter also, the
shaft in the gear.
2 The rotating speedunder work is fairly high, with
the turning speed of 3000-6000 units. Its service lifetime is actually 22000
hours.
3 It could actually carry huge shock and vibration load.
4
It offers a high requirement for the precise of the supporting position to the
shaft.
