Abstract
A kind of fan-shaped lubricating pad of Hydrodynamic-static Thrust Bearings in Water Turbo rectangle arc chamber.The utility model is related to a kind of Hydrodynamic-static Thrust Bearings in Water Turbo, and low to solve the fan-shaped lubricating pad bearing capacity of existing large scale, the scope of application is small, take up space than it is larger the problems such as.It is known that hydrodynamic bearing bearing capacity is high, but hydrodynamic bearing start or stop, under the conditions of low-speed heave-load and commutation all it cannot be guaranteed that form hydrodynamic lubrication, and hydrodynamic bearing rigidity is poor.Each advantage devises a kind of fan-shaped lubricating pad of Hydrodynamic-static Thrust Bearings in Water Turbo rectangle arc chamber to comprehensive dynamic and static pressure thrust bearing.Lubricating pad main body is sector, and it is a circular shape that the oil pocket vertical direction of lubricating pad, which is seen, and vertical view is that a rectangle is symmetrical positioned at lubricating pad geometric center, and a fuel feed hole is machined with oil pocket, and lubricating pad sector main body both sides process an oil-recovery tank respectively.The utility model is used to carry platen.
Description
Technical field:
The utility model is related to a kind of lubricating pad of Hydrodynamic-static Thrust Bearings in Water Turbo.
Background technology:
With the development of modern industry, rotating machinery increasingly develops towards accurate, high speed, heavily loaded direction.Hydrostatic bearing
Wear and tear all smaller in startup or docking process, do not wear and tear even, long lifespan.And hydrodynamic bearing is starting or stopped
All it cannot be guaranteed that forming hydrodynamic lubrication, and hydrodynamic bearing rigidity is poor under the conditions of car, low-speed heave-load and commutation.Then sound
It is very valued a kind of Novel bearing structure in recent years that last item, which is held, it combine hydrodynamic bearing and hydrostatic bearing integrate it is excellent
Point, good oil film rigidity and good load-carrying properties, its good bearing capacity can be kept from the slow-speed of revolution to high rotating speed
Depending on bearing arrangement, charge oil pressure, the condition such as rotary speed.
The content of the invention:
The purpose of this utility model is to design a kind of fan-shaped lubricating pad of Hydrodynamic-static Thrust Bearings in Water Turbo rectangular cavity, solves large scale and fan
The small shortcoming of shape lubricating pad carrying scope.
The utility model solves the technical scheme that its technical problem used：A kind of Hydrodynamic-static Thrust Bearings in Water Turbo rectangle arc chamber
Fan-shaped lubricating pad includes lubricating pad main body, and lubricating pad main body is sector, and it is a circular shape that the oil pocket vertical direction of lubricating pad, which is seen, and vertical view is one
Rectangle is symmetrical positioned at lubricating pad geometric center, and a fuel feed hole, lubricating pad sector main body both sides difference are machined with oil pocket
Process an oil-recovery tank.
The utility model is compared with existing fan-shaped lubricating pad with advantages below：By the annular cloth of 24 the utility model lubricating pads
Put on hydrostatic thrust bearing, hydrostatic thrust bearing is arranged on large scale lathe base, is then arranged on platen
Above lubricating pad, hydraulic oil is continuously sent into fuel feed hole by oil pump, makes support member and one layer is formed between support member
Hydrodynamic oil film, its lathe base and workbench are separated, and lubricate its fully liquid.When lathe startup work, machine tool chief axis
Rotate at a high speed, workbench rotates also with high speed, so that platen and fan-shaped lubricating pad relative motion, because of lubricating pad vertical cross-section
Arc-shaped cavity forms wedge gap in the movement direction with horizontal oil film, and dynamic pressure oil film, dynamic pressure will be produced according to dynamic pressure oil film theory
The generation of oil film will greatly improve the bearing capacity of oil film, and empirical tests dynamic and static pressure loading capacity of oil film brings up to 25% to 200%,
Effectively solve the low shortcoming of hydrostatic support bearing capacity.
Brief description of the drawings:
Fig. 1 is the three-dimensional front view of the utility model, and Fig. 2 is the utility model 3-D view top view, and Fig. 3 is that this practicality is new
The whole lathe lubricating pad of type oil film.
Embodiment:
Illustrated according to Fig. 1-3, Hydrodynamic-static Thrust Bearings in Water Turbo arc-shaped cavity lubricating pad includes lubricating pad main body 1, lubricating pad main body is sector, oil
It is a circular shape 2 that the oil pocket vertical direction of pad, which is seen, and vertical view is that a rectangle is symmetrical positioned at lubricating pad geometric center, on oil pocket
A fuel feed hole 5 is machined with, oil-recovery tank 3 and 4 is processed respectively in the fan-shaped main body both sides of lubricating pad.By 24 the utility model lubricating pads 6
It is circular layout on hydrostatic thrust bearing, hydrostatic thrust bearing is arranged on large scale lathe base, then by platen
Above lubricating pad, hydraulic oil is continuously sent into fuel feed hole 5 by oil pump, makes support member and by shape between support member
Into one layer of hydrodynamic oil film, lathe base is separated with workbench, its fully liquid is lubricated.When lathe startup work, lathe
Main shaft rotates at a high speed, and workbench rotates also with high speed, so that platen and fan-shaped lubricating pad relative motion, because lubricating pad is vertical
Section arc-shaped cavity forms wedge gap in the movement direction with horizontal oil film, and dynamic pressure oil film will be produced according to dynamic pressure oil film theory,
The generation of dynamic pressure oil film will greatly improve the bearing capacity of oil film, empirical tests dynamic and static pressure loading capacity of oil film bring up to 25% to
200%, effectively solve the low shortcoming of hydrostatic support bearing capacity.
