Product Details
Flange copper sleeve fluid film lubrication for automotive machinery.
Description
The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.
Between the two friction surfaces, it is completely separated by the fluid film of the lubricant, and the external load is balanced by the pressure of the fluid film, so that the movement friction of the two friction surfaces becomes the internal friction of the fluid, which is called fluid film lubrication. Fluid film lubrication is an ideal lubrication state.
There are two ways to form fluid film lubrication, one is hydrostatic lubrication, and the other is hydrodynamic lubrication.
Hydrostatic lubrication: is to inject a certain pressure of liquid
lubricant into a special cavity between two friction surfaces, and
then the lubricant overflows through the surface gap around the
cavity to form a fluid film static pressure between the two
friction surfaces. Separate the two friction surfaces to achieve
hydrostatic lubrication. This method is suitable for the
lubrication of hydrostatic bearings or parallel low-speed movement
of two friction surfaces, and is not suitable for the lubrication
of point-line and other high pair contact, such as the lubrication
of gear transmission.
Hydrodynamic lubrication: liquid lubricant is injected into the
entrance of the two friction surfaces. The relative movement speed
between the two friction surfaces draws the lubricant into the
working area of the friction surface to generate dynamic
pressure, forming a fluid dynamic pressure to separate the two
friction surfaces. , Realize hydrodynamic lubrication. This method
is suitable for the lubrication of conjugate friction surfaces with
a certain speed of movement. Therefore, it is suitable for the
lubrication of gear transmission.
