Description
Technical field
The present invention relates to selfaligning roller bearing, especially relate to a kind of selfaligning roller bearing having angle compensation function and vibration-damping function concurrently.
Background technique
Along with society's constantly progress, not only the overall qualities of people are had higher requirement, and more modern requirement is proposed to our processing manufacturing industry, require product constantly toward light, small and exquisite and powerful etc. future development, and this developing direction is propose higher level requirement to the machining accuracy of machining equipment after all.Therefore, installation precision when we need the manufacturing precision of raising component and component to install.The manufacturing of the product of present many enterprises has a set of fairly perfect full-automatic or semiautomatic production equipment, which greatly enhances the manufacturing efficiency of product, but it is all the same that the quality of the product that the production line that practice tells us such is produced is not for each and every one, defect rate also needs to reduce further, the reason producing this situation has a lot, one of them reason is on automatic line and itself exists precision problem, if provide a kind of bearing, magnetic flow liquid (a kind of intellectual material) is added inside bearing, can perception outside environment change and make suitable response, so just can be run by our parameter set in advance, just can greatly reduce the spatial motion error that manufacturing error and alignment error due to part cause in such event, this intellectual material has the function of vibration reduction and cushioning, so the mechanical vibration of a part can be absorbed, turn eliminate the machining error owing to vibrating caused machinery, and the structure of this bearing is simple, easy to process, cost is low and its transmitting torque has controlled function.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of selfaligning roller bearing having angle compensation function and vibration-damping function concurrently.The feature that device has is: decrease the spatial motion error that manufacturing error and alignment error due to part cause; And there is the function of vibration reduction and cushioning in addition, the mechanical vibration of a part can be absorbed; And the structure of this bearing is simple, easy to process, cost is low and its transmitting torque has the feature such as controlled.
In order to effectively realize the function and characteristic as above, the present invention realizes as follows: device is mainly by outer ring, and inner ring, rolling element, retainer, cage ring, electromagnetic coil, spiral type oil sealing groove, magnetic flow liquid forms.Be connected by rolling element between inner ring with outer ring, rolling element is positioned by retainer; Bearing inner race has the annular groove of similar circular arc, and annular groove both sides are designed to spiral type oil sealing groove, and magnetic flow liquid is filled in this annular groove intermediate portion, is full of oily object, for the sealing of magnetic flow liquid, is referred to as oil sealing in the spiral sealing groove at two ends; The characteristic of oily object is high viscosity, lazy flow, and immiscible with the base load liquid in magnetic flow liquid; Bearing inner race has groove, and itself and magnetic flow liquid inside this groove, and are isolated by cage ring by electromagnetic coil.The material of the material of outer ring, rolling element and retainer is non-magnet material, and inner ring is the material that magnetic property is good.
When having angular error between the bearing support at the axle two ends caused by the foozle of component and alignment error, it is large that usual axle will overcome the moment that the force rate self required for this error will transmit in the process run, based on this feature, in advance by regulating the size of current flowing through electromagnetic coil, thus the magnetic field of some strength is produced in the space at inner ring and magnetic flow liquid place, make magnetic flow liquid generation rheological phenomena, (size of this power is greater than the moment that axle will transmit finally to allow magnetic flow liquid have certain shear yielding power, be less than the power overcome needed for error), so, the shear yielding power that magnetic flow liquid has can occur to flow thus can keep again the validity of transmission while compensating error, in addition magnetic flow liquid can absorb a part of mechanical vibration, thus has cut down the parts machining foozle caused by mechanical vibration.
A kind of good effect having the selfaligning roller bearing of angle compensation function and vibration-damping function concurrently of the present invention is: the rheological phenomena utilizing magnetic flow liquid, magnetic rheology effect is controlled in certain intensity, reach the function of compensating error, in addition magnetic flow liquid can absorb a part of mechanical vibration, thus has cut down the parts machining foozle caused by mechanical vibration.And the structure of this bearing is simple, easy to process, cost is low and its transmitting torque has controlled etc. feature.
Accompanying drawing explanation
Fig. 1 is a kind of internal structure principle schematic having the selfaligning roller bearing of angle compensation function and vibration-damping function concurrently of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in more detail.
As shown in Figure 1, a kind of selfaligning roller bearing having angle compensation function and vibration-damping function concurrently of the present invention, this device is mainly by outer ring 1, and inner ring 2, rolling element 3, retainer 4, cage ring 5, electromagnetic coil 6, spiral type oil sealing groove 7, magnetic flow liquid 8 forms.Be connected by rolling element 3 between inner ring 2 with outer ring 1, rolling element 3 is positioned by retainer 4; Bearing inner race 2 has the annular groove of similar circular arc, and annular groove both sides are designed to spiral type oil sealing groove 7, and magnetic flow liquid 8 is filled in this annular groove intermediate portion, is full of oily object, for the sealing of magnetic flow liquid 8, is referred to as oil sealing in the spiral sealing groove 7 at two ends; The characteristic of oily object is high viscosity, lazy flow, and immiscible with the base load liquid in magnetic flow liquid 8; Bearing inner race 2 has groove, and itself and magnetic flow liquid 8 inside this groove, and are isolated by cage ring 5 by electromagnetic coil 6.The material of the material of outer ring 1, rolling element 3 and retainer 4 is non-magnet material, and inner ring 2 is the material that magnetic property is good.
