The slide bearing, operating under sliding friction, works reliably, smoothly and noiseless.
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 provides the skills of absorbing vibrations though friction resistance.
The part that is supported by the bearing is known as the journal also, the part matched with it is known as the bearing bush. To be able to enhance the friction on the surface of bearing bush, on the inner surface of bush, a material layer for decreasing friction was cast, that is known as the bearing linear.
The material for producing the bearing bush and also the bearing layer are known as with a joint name of sliding bearing material. The sliding bearing is primarily utilized under the condition of low speed and high load or used within the running parts which are difficult to be maintained and lubricated.
The Classification of Sliding Bearing according to the direction where the load is applied, it could be classified into the thrust sliding bearing and also the radial sliding bearing. The Thrust Sliding Bearing: The direction of their load is paralleled with 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 way of the lubrication slick, this could be classified into the hydrodynamic sliding bearing and the aerodynamic bearing. The hydrodynamic sliding bearing: Due to the geometry shape and also the relative motion in between the vice-surfaces of relative motion and also by the assist of viscosity of fluid, the lubricant could be injected on the friction surface and then the motion vice-surfaces could be separated via the natural fluid film, that is known as the hydrodynamic lubrication. The aerodynamic bearing: Inject the high-pressure lubricant on the surfaces in between the sliding bearing in addition, the axle journal to carry the outside load and separate the motion vice-surfaces, which is sometimes called aerodynamic lubrication.
If slide bearing lubricated with liquid, the friction could be decreased significantly. As the sliding bearing is of wonderful friction loss and low efficiency and it actually is difficult to maintain in lots of working parts, for example the machine approach, the motor vehicle using the reduction gear box, it is often taken location by the rolling bearing.
However it still performs a significant part in lots of special conditions.
1 According to the assembly requirement, it's been made up of the mode of quarter-cut: The crank axle of the starter also, the shaft of the gear.
2 The rotating speedunder work is fairly high, with the rotating speed of 3000-6000 rounds. Its service lifetime is 22000 hours.
3 It could carry huge shock and vibration load.
4 It offers a high requirement for the precise of the supporting position on the shaft.
