problem mechanical dimensioning hydrostatic bearings

[moreno4]

good weekend to all, I am always dying, studying constructions of machines and going to strip the niemann and in some texts in English I struggle to find the problem of calculation to mechanical dimensioning for how to dimensional of the hydrostatic radial bearings, for those regiments pushed ness issue because with the johns in the 1 vol speaks but for those radial carriers I struggle to find a treat as well in the johns, so I ask if someone . .more

hydrostatic bearings are born many decades ago, mainly to float heavy components. for this nature their representation and application is the flat one.

hydrostatic is not hydrodynamic, so I hope you're asking "static."

the folds are found both on the sighley's and on the niemann to 3 volumes. I'll take my notes back.

excellent dispenses as usual mechanicalmg. Can I ask what book did you get the charts from? ? ?

18 years have passed ... I went to look and on shigley's mechanical engineering design there is all treatment complete with these graphs, heat calculation, flow rate etc.

thanks for the notes, mechanics mg, but what I wanted to understand was how to check the pitting of a hydrostatic bearing, I was wondering this question because if in theory the oil should float the heavy pin at a certain pressure considering also the outflow of oil due to the premises of the wells, the pin not going in contact with the bushing, should not create direct pitting and therefore perhaps not be verified the usury pin. Let me understand if my hypothesis and correct mechanical mg, thank you for your good availability. .

as explained in the very old dispensers of hydrostatic skates of the innse when they built machines and plants for the iron and steel industry and the division of the sockets, explained that the oleostatic bearings are sinisurano only if the oil is contaminated by abrasives or if the pressure is not enough to support the load and therefore the scratched skate on the guide.

In essence it is good that in order to avoid possible accidental grippaure, the skate and the guide are not of the same material but it is not necessary because the two surfaces from the oil will always be separated.

the same goes x hydrostatic radial bearings as I assumed? and that therefore the verification should be made only x the pressure of the oil and not for the contact between pin and crawling seat?

 

[meccanicamg]

the same goes x hydrostatic radial bearings as I assumed?

What will change?
if it floats and the oil does not have mechanical rubbing.

mechanical thanks you see that you are prepared, I am pleased that you are of help for all the times I need to ask for your precious information. . .

I am here, what I don't know I try to learn and try to keep me in practice, even if I don't use everything I learn.
for me is a pleasure, a passion, a vocation ,
