Description
Technical field
The utility model relates to lubricating bearings field, relates in particular to a kind of dynamic pressure compensation mechanism of hydrostatic lubrication thrust bearing.
Background technology
In the last few years, along with heavy duty appearance at a high speed, country started to strengthen the lubricated research dynamics of hybrid, but also little for the developmental research of thrust bearing, high-speed overload lubrication technology is still far from perfect. In actual applications, the lubricated effect of hybrid is increasing, existing pure static pressure technology can not meet the requirement of high-speed overload working condition high precision and high stability, in producing, real life can often there is the phenomenon of lubrication failure, lubrication failure not only can reduce operating efficiency, strengthen the consumption of the energy but also can destroy the processing of part, damage machine, more serious meeting brings casualties, brings economic loss to country.
Summary of the invention
The utility model, for prior art above shortcomings, provides a kind of dynamic pressure compensation mechanism of stable a kind of hydrostatic lubrication thrust bearing.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of dynamic pressure compensation mechanism of hydrostatic lubrication thrust bearing, comprise hydrostatic bearing main body, dynamic pressure compensation block, workbench, described workbench cross section is annular, described workbench top has multiple hydrostatic bearing main bodys, described hydrostatic bearing main body is evenly distributed on workbench, described hydrostatic bearing main body top has static-pressure oil chamber, described static-pressure oil chamber inside has lubricating oil, described lubricating oil forms oil film at static-pressure oil chamber, described oil film inside has dynamic pressure compensation block, described dynamic pressure compensation block moves in oil film, and described dynamic pressure compensation block one end has key groove.
Described static-pressure oil chamber bottom has oil supplying hole, and described oil supplying hole connects oil pump by oil-filter pipe, and described static-pressure oil chamber comprises fan-shaped static-pressure oil chamber, Rectangular Hydrostatic oil pocket, trapezoidal shape static-pressure oil chamber.
Beneficial effect:
Workbench top has multiple hydrostatic bearing main bodys, described hydrostatic bearing main body top has static-pressure oil chamber, described static-pressure oil chamber inside has lubricating oil, described lubricating oil forms oil film at static-pressure oil chamber, described oil film inside has dynamic pressure compensation block, described dynamic pressure compensation block one end has key groove, in the time that workbench starts to rotate, dynamic pressure compensation block also can be along with rotation, because dynamic pressure compensation block has key groove, under the structure function of this wedge shape, make dynamic pressure compensation block can and upper strata oil film between form a longitudinal ring-type wedge-shaped oil film, this wedge-shaped oil film plays the effect of stable support upper strata oil film, improve the bearing value of static pressure, when the higher static pressure bearing capacity of rotary speed loses larger, the dynamic pressure effect that dynamic pressure compensation block produces is more obvious, ensure the operation of lathe high-accuracy stable. described static-pressure oil chamber bottom has oil supplying hole, described oil supplying hole connects oil pump by oil-filter pipe, in use, oil pump feeds the lubricating oil with certain pressure to static-pressure oil chamber inside by oil supplying hole, utilize the pressure differential between static-pressure oil chamber, form the bearing capacity of hydrostatic bearing main body, by bearing spindle buoyance lift and bear external applied load, under the effect of dynamic pressure compensation block, ensure its high-accuracy stable operation, and can reduce because the too high generation oil film of speed splashes, cause dynamic pressure effect to decline, the hydrostatic lubrication effect of this kind of structure is very remarkable, carrying to lathe and raise speed significant, the dynamic pressure compensation mechanism of this hydrostatic lubrication thrust bearing has improved high-speed overload extreme operating condition precision now, simultaneously stable.
