Abstract

The bearing for a shaft turning at high RPM has a floating bush installed in a housing. Each floating bush (3,4) on the end face (8,10) sides facing the shaft (2) has radially outwards extending, ring-form recesses (11,12) formed by inclined faces, and the inside diameter (13) of the locating discs (6,7,9) adjacent to the end faces is smaller than the radial height of the recesses. Radially extending slots (15,16) are located in the end face sides and/or in the locating discs.

Description

The bearing that is used for the axle of high speed rotating
The present invention relates to a kind of bearing that is used for the axle of high speed rotating, have and be arranged in a floating bush in the housing.
Task of the present invention is with a kind of like this bearing of simple means structure, dying oscillation excitation effectively.
According to the present invention, above-mentioned task is achieved in that floating bush has the annular breach that radially outward narrows down in the front side end in the face of axle, and adjacent internal diameter against plate with proof is less than the radial height of breach.
In this design proposal, in breach, gathered oily deposit, when the floating bush oscillatory movement, guaranteed the good lubrication of bush face to the face of housing.Here, the oil deposit has prevented that air from entering in the gap between plate and the lining, thereby causes decay to be interrupted.
According to a kind of design proposal of the present invention, positive and/or in plate, arranging radial slot.Also guarantee that enough oil masses form the external lubrication film even realize thus when very little in the gap between plate and lining.
Further feature and advantage are done to describe by dependent claims with reference to accompanying drawing and are provided.
Fig. 1 is by the longitudinal section according to bearing critical piece of the present invention.
Fig. 2 and corresponding second kind of embodiment shown in Figure 1.
With 1 stationary housing of representing bearing, represent axle among Fig. 1 with 2.Axle 2 is by 3,4 supportings of two floating bushes.A dividing busing 5 is arranged between two linings 3,4, and this dividing busing 5 stops rotation by a straight pin 32.In addition, bearing by outside dish type against plate 6,7 to outer closure.
Lining 3 is arranged in dividing busing 5 and against between the plate 6, axial clearance is arranged.In addition, dividing busing 5 stops rotation by a straight pin 32, wherein this straight pin be fixed in the housing and be embedded into one of dividing busing 5 corresponding at least along in the breach that movement clearance axially is provided 33 of axle 2, this breach for example is a larger-diameter hole or a deep hole.
Lining 3 in the face of of dividing busing 5 being had the breach 11 or 12 of an annular respectively in the front 10 of plate 9 against front 8 neutral planes of plate 6, this breach is limited by an inclined-plane.Breach 11,12 radially outwards narrows down.Against the internal diameter of plate 6 radial height less than breach 11.Because this design proposal can form the oil deposit in breach 11 abaxial parts.This oil deposit be used for when lining 3 oscillatory movements not can with the air inspiration it and coil between 6, thereby between housing 1 and lining 3, keep constant lubricant film to encourage with dying oscillation.
In order when axle 2 rotating speeds are low, to guarantee between lining 3 and the housing 1 enough lubricating films are arranged, radial groove 15,16 can be set in the front of lining 3.Certainly these grooves also can be arranged on against plate 6 or 7 in the face of on the face of lining 3.
At the other end of housing 1 is that the structural configuration of floating bush 4 is the same.
According to embodiment shown in Figure 2 and shown in Figure 1 basic identical.Here be provided with a housing 17, this housing has the lining 20,21 that is used to float against plate 18,19.The axial outside motion of lining 20,21 is limited against plate 22,23 again.In the front 24,25 of lining 20 breach 26,27 is set, these breach constitute by the cutting with curved interface.Here, against the internal diameter 28,29 of plate 18,22 also less than the radial height of breach 26,27, thereby can gather oil deposit 30 or 31, prevent that thus air from entering in the lubricant film between housing 17 and the lining 20.The structure of lining 21 and supporting and top similar.
When application is of the present invention, not only dying oscillation excitation well, and make the frictional work of bearing more favourable.
