Abstract
The invention discloses a self-adapting three-directional high-pressure hydraulic bearing, which comprises an outer bearing jacket, an end cover arranged on the outer bearing jacket, and an inner bearing sleeve arranged inside the outer bearing sleeve. A sealing piece is arranged in the position where the end cover of the outer bearing sleeve is in contact with the inner bearing sleeve; high-pressure liquid filling the gap between the inner bearing sleeve and the outer bearing sleeve is affused in the gap between the outer bearing sleeve and the inner bearing sleeve. The bearing can greatly reduce the friction loss of the shaft in rotation, and run stably without noise; the radial and axial force is evenly applied thereon; besides, the bearing can automatically adjust the balance position of the shaft and has good centring performance.
Description
Technical field
The present invention relates to a kind of self-adapting three-way positioning high pressure liquid bearing.
Background technique
The drive bearing that is used for mechanical field at present mainly contains two kinds on rolling bearing and sliding bearing, and these two kinds of bearings structurally all are that bearing directly contact with axle, can produce very big friction in the time of rotation, cause and vibrate and noise, and cause huge energy loss.In addition, the non-constant of the adaptive ability of these two kinds of bearings after axle has off-centre or bearing that wearing and tearing are arranged, can not carry out the oneself and adjust, and can cause the fluctuation of service of equipment, even cause the inefficacy of entire equipment.
Chinese patent CN86104100 number disclosed pneumatic bearing though avoided direct contact of bearing with axle, reduces friction loss significantly, because gas density is low, bearing capacity is low, is not suitable for the high speed and high pressure occasion; Simultaneously, this bearing can not bearing axial pushing force, and complex structure, inconvenient operation, and practicability is lower.
Summary of the invention
The object of the present invention is to provide a kind of vibrations and noise little, exempt friction energy loss, adaptivity is good, centering function admirable, stable three-way positioning high pressure liquid bearing.
The objective of the invention is to be achieved through the following technical solutions: it comprises bearing outside, be located at the end cap on the bearing outside, place the bearing inner sleeve in the bearing outside, the end cap of described bearing outside and bearing inner sleeve contacting point are provided with Sealing, space between described bearing outside and bearing inner sleeve is perfused with the highly pressurised liquid that is full of bearing inner sleeve and bearing outside space.
Described bearing inner sleeve is provided with the shaft shoulder corresponding to bearing outside end cap one side.
Described Sealing can be selected rubber seal for use.
In normal operation, axle is being with bearing inner sleeve to rotate, and bearing outside is motionless, is isolated by highly pressurised liquid between bearing inner sleeve and the overcoat, will significantly reduce friction like this, reduces noise, energy consumption; Simultaneously, because liquid has the effect of buffering absorbing, so the vibration can reduce equipment operation the time.
Because the free-flow performance of liquid has determined that its internal pressure is equally distributed, be that the pressure that highly pressurised liquid is applied on the bearing inner sleeve all directions is the same, so when a certain direction of axle deflection, will break pressure balance in this, so, under action of pressure, high pressure oil can automatically be adjusted to bearing inner sleeve on the position of balance, the adaptivity of Here it is middle (center) bearing of the present invention.
The present invention can make axle frictional loss in rotation process significantly reduce, and is stable, noise free, and radial-axial is stressed evenly, the equilibrium position of automatic adjusting axle, centering function admirable.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is embodiment illustrated in fig. 1 and an axle assembling condition schematic representation.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to accompanying drawing: present embodiment comprises bearing outside 1, be located at the end cap 5 on the bearing outside 1, place the bearing inner sleeve 2 of bearing outside 1 inside, the end cap 5 and bearing inner sleeve 2 contacting points of described bearing outside 1 are provided with rubber seal 4, gap between described bearing outside 1 and bearing inner sleeve 2 is perfused with the highly pressurised liquid 3 that is full of space between bearing inner sleeve 2 and the bearing outside 1.
Like this, the bearing inner sleeve 2 that is connected with axle 7 is suspended in the highly pressurised liquid 3, under free state, because the effect of highly pressurised liquid 3, bearing inner sleeve 2 is understood to bearing (ball) cover 5 movement outside, so, be provided with the shaft shoulder 6 at bearing inner sleeve 2 corresponding to end cap 5 one sides of bearing outside 1, it can be had an effect with the end cap 5 of bearing outside 1, thereby stops the motion of bearing inner sleeve 2 to end cap 5 outsides, plays the effect of an axially locating.In bearing outside 1 end cap 5 and bearing inner sleeve 2 contacting points installing rubber seal 4, mainly play sealing and dust-tight effect.
As shown in Figure 2, the bearing that present embodiment provided generally is paired use.Connecting format between axle 7 and the bearing inner sleeve 2 has a variety of, can select stressed joint, also can options button or spline connection.To give axle 7 one axial precompressions when mounted, the value of precompression is greater than or equals the maximum axial force or the maximum radial force (getting the maximum value among both) of axle 7, after applying precompression, between the shaft shoulder 6 of bearing inner sleeve 2 and the end cap 5 of bearing outside 1 certain clearance has been arranged, and this gap is filled up by highly pressurised liquid 3.Like this, the bearing inner sleeve 2 that is connected with axle 7 just is suspended in the highly pressurised liquid 3, in the equipment proper functioning, axle 7 is being with bearing inner sleeve 2 to rotate together in highly pressurised liquid 3, because highly pressurised liquid 3 has advantages such as friction is little, buffering absorbing, pressure is even, so the present invention can reduce friction, save energy consumption well and reduce noise etc.
