Description
Technical field
The present invention relates to a kind of big carrying static pressure ball head articulated mechanism with internal-feedback throttling device, belong to Machine Design neck
Domain.
Background technology
Button-head hinge be a kind of end is enclosed in mechanism in ball-and-socket for the rod member of bulb, be face between bulb and ball-and-socket
Contact, contact area is bigger between the two, and specific contact pressure is less, and the working life of ball head articulated mechanism is longer.However, with system
Make equip towards maximizations, heavy loading, high speed development trend, this kind of ball head articulated mechanism heavy duty with swing in high frequency under,
The larger force of sliding friction that will produce between bulb and ball-and-socket, caloric value is big, leads to frictional dissipation between bulb and ball-and-socket to add
, even there are both and is mutually twisted, working life is greatly shortened in play.In order to reduce the friction between bulb and ball-and-socket, go out
Add now the rolling ball head articulated mechanism of roller between ball-and-socket and bulb, but the bearing capacity rolling ball head articulated mechanism is inclined
Little, impact resistance relatively low it is impossible to meet the demand of severe duty；Also there is the appearance of static pressure button-head hinge in recent years, but all
Using the throttle style of level pressure oil supply system, its unit area bearing capacity less it is impossible to meet severe duty.
Content of the invention

Road and upper internal feedback path enter upper static pressure chamber.Extreme pressure lubricant produces downward power in upper ball-and-socket, produces in lower ball-and-socket
Power upwards, because the lubricating oil of upper ball-and-socket is to flow through lower static pressure chamber and lower oil sealing surface by the lubricating oil in lower ball-and-socket, enters back into
Upper ball-and-socket, therefore descend the lubricating oil pressure that in ball-and-socket, lubricating oil pressure will be greater than in ball-and-socket, both are only poor to be spherical hinge
The bearing capacity upwards that chain can be provided by.
When bulb bears downward external load, bulb will produce downward displacement, thus leading to lower oil sealing surface gap
Reduce, liquid resistance increases, and will increase through the lubricating oil pressure that orifice restriction device enters lower static pressure chamber, and through lower internal feedback path and upper
The lubricating oil pressure that internal feedback path enters upper static pressure chamber will reduce, and the pressure differential ultimately resulting in ball-and-socket and lower ball-and-socket increases
Greatly, that is, increase the bearing capacity of spherical linkage.
Beneficial effect：A kind of big carrying static pressure button-head hinge with internal-feedback throttling device proposed by the present invention has carrying energy
Power is especially big, and flow of lubrication is little, the low advantage of friction power loss.
