Description
Technical field
The present invention relates to a kind of rotation support device.
Background technology
Continued to develop with mach, the demand of high-precision Digit Control Machine Tool is increasing, and bearing is used as numerical control machine
The part largely used in bed, machining accuracy, performance to lathe play highly important effect.Bearing when in use one
As be inner ring set on the rotating shaft, outer ring is fixed in fixed seat, realizes the rotational support of countershaft.Traditional bearing is usually
Directly coordinate the positioning for realizing countershaft axis with the endoporus side face of fixed seat by the outer peripheral face of its outer ring, but turn in rotating shaft
When being vibrated during dynamic, because contact of the outer ring with fixed seat is rigid contact, this is just easy to the transmission of aggravation vibration,
Substantial amounts of noise is produced, very big obstacle is brought to the stability that rotary shaft is rotated, the use longevity of fixed seat and bearing is reduced
Life, influences the normal operation of equipment, the machining accuracy of lathe is largely effected on, while can not be applied to Ultra-High Speed Machine Tools.
The content of the invention
It is existing to solve it is an object of the invention to provide a kind of bearing and the rotation support device of fixed seat flexible contact
Some bearings and fixed seat rigid contact, vibration is larger, can not realize the problem of ultrahigh speed is rotated.
In order to solve the above-mentioned technical problem, rotation support device of the invention is adopted the following technical scheme that：One kind rotates branch
Support arrangement, including bearing and bearing block, are folded with the setting of at least two axially spaced-aparts between bearing outer ring and inner hole of bearing seat face
O-ring seal, the opposite flank of two neighboring O-ring seal, the outer peripheral face of bearing outer ring and inner hole of bearing seat face are enclosed jointly
Into the annular damper space for filling damping liquid, bearing outer ring and/or bearing block, which are provided with, to be used for annular damper space
The liquid injection hole of interior injection damping liquid.
The damping liquid is lubricating oil, and the bearing outer ring is provided with enters axle for the lubricating oil in annular damper space
Hold the excessively oily passage of inside.
The inner peripheral surface of bearing outer ring has rolls the raceway coordinated with rolling element, and the excessively oily passage has and the raceway
The pore oil-out of connection.
The excessively oily passage also includes being filled with sea in the shoe cream room positioned at pore oil-out upstream, the shoe cream room
It is continuous.
The excessively oily passage includes the big footpath blind hole extended radially inwardly by the outer peripheral face of bearing outer ring and outside bearing
The path blind hole that the rolling track and radial of the inner peripheral surface of circle extends internally, shoe cream room is the inner chamber of big footpath blind hole, and pore oil-out is
The aperture of path blind hole, the centerline parallel of big footpath blind hole and path blind hole and is staggered in the axis direction of bearing ring, big footpath
Blind hole is intersected with path blind hole and connected by bottom.
The excessively oily passage has multiple and circumferential uniform, is additionally provided with that to be sequentially connected each big footpath blind on the lasso body
The annular oil guide groove in hole.
It is folded between the bearing outer ring of the rotation support device of the present invention and inner hole of bearing seat face between at least two axial directions
Every the O-ring seal of setting, the opposite flank of two neighboring O-ring seal, the outer peripheral face of bearing outer ring and inner hole of bearing seat face
Surround the annular damper space for filling damping liquid jointly, the annular damper space between such bearing and bearing block by its
Interior damping liquid surrounds annular damper layer, can provide bearing the support force of radial direction, and the support provided by damping liquid
For flexible support, vibration can be substantially reduced, impact is absorbed, while damping liquid is circumferentially distributed can to make the circumferential load of bearing
It is evenly distributed, rotates more steady.
Further, damping liquid is lubricating oil, and such lubricating oil can enter Bearing inner by excessively oily passage, to axle
Hold and be lubricated, and the lubricating oil in annular damper space can play a part of being supported bearing, so not only
The lubrication of bearing is realized, the purpose of spring bearing has been reached again.
Further, excessively oily passage connects the raceway of lasso body by pore, reduces the inlet of lubricating oil, keeps away
The amount for exempting from lubricating oil excessively causes to waste, and when rolling element is rotated, rolling element can be by the lubricating oil at pore oil-out
Take out of and then lubricating oil is coated on rolling element and raceway so that lubrication ratio is more uniform, it is adaptable to which bearing ultrahigh speed is rotated, will not
Get rid of oily phenomenon.
Further, sponge is filled with excessively oily passage shoe cream room, sponge can reduce lubricating oil and enter axle when in use
Interior flow of lubrication is held, lubricating oil is absorbed by the sponge and entered after oozing out by pore oil-out in bearing, reduces
The speed that lubricating oil enters in bearing, so controlling the amount of the lubricating oil injected into excessively oily passage can control lubricating oil to enter
The flow of bearing causes lubricating oil to meet use, it is to avoid lubricating oil is excessive and causes to waste.
