The self-lubricating guiding device at least has the advantages of self-lubricating guiding function, oil leak potential hazard prevention, cost conservation, compensation function, dead locking prevention, accuracy in guiding, high lateral rigidity, and reliability in operation.
Description
Technical field
The utility model relates to a kind of guiding device, relates in particular to a kind of selflubricating guiding device that has compensate function, and it can be applicable in the equipment such as vibrating table.
Background technique
Electrodynamic vibration generator is mainly used in the product complete machine of departments such as Aeronautics and Astronautics, weapons, electronics, boats and ships, machinery, the energy, chemical industry, instrument and apparatus and the reliability trial of component, also can be used as the characteristic research of structural dynamics etc.Working principle is that field coil feeds direct current generation stationary magnetic field, and the drive coil cutting magnetic line in the stationary magnetic field that feeds Ac produces electromagnetic force, if change current direction, will produce corresponding alternate motion, i.e. electricity → magnetic → power.Its structure mainly is made up of activity system (moving-coil and drive coil), magnetic circuit system, flexible support system, guidance system and cooling unit etc.
Wherein guidance system is an a kind of kinematic constraint mechanism, and unnecessary transverse movement is accurately located and limited to its effect to moving-coil exactly, thereby guarantees moving-coil to-and-fro motion in the axial direction.Usually in electrodynamic vibration generator, guidance system is divided into two kinds of guide mechanism and lower guide mechanisms.Traditional lower guide mechanism mainly contains roller guiding, linear bearing guiding and static pressure filmatic bearing guiding etc.; Wherein the wearing and tearing of roller guiding are very fast; The gap that often needs the adjustment roller and the axis of guide, and if the improper moving-coil table top uniformity and the acceleration waveform distortion factor of also can influencing of adjustment; The linear bearing guiding accuracy is relatively poor, and lateral rigidity is not high; Static pressure filmatic bearing guiding is bigger because of comprising the oil supply system volume, complex structure, and cost is high, and has leakage of oil hidden danger.
The model utility content
The purpose of the utility model is to propose a kind of selflubricating guiding device with compensation, and this guiding device is wear-resistant, guiding accurately, selflubricating and do not have leakage of oil hidden danger, reliable in function, thereby overcome deficiency of the prior art.
For realizing above-mentioned model utility purpose, the utility model has adopted following technological scheme:
A kind of selflubricating guiding device with compensation; It is characterized in that: it comprises the axis of guide and self oiling bearing; The axis of guide is coaxial to be arranged in the self oiling bearing, sheathed successively bearing inner race and bearing outside on the said self oiling bearing, and between bearing inner race and the bearing outside elastomeric layer is set.
Preferably, said axis of guide surface is provided with ceramic material layer.This ceramic material layer preferably adopts the oxide ceramic material coating that is plated in axis of guide surface.
Said self oiling bearing is to be matrix with the steel plate, the spherical bronze powder of intermediate sintering, and surface rolling teflon and plumbous mixture roll the sliding bearing that forms then.
Preferably, said bearing inner race outer wall and/or bearing outside inwall are provided with circular groove, and the regional area at least of said elastomeric layer is embedded in the said circular groove.
Particularly preferred, said elastomeric layer is the vulcanized rubber layer.
As one of possible implementation, said self oiling bearing is fixed in through pressure ring in the central magnetic pole endoporus of electrodynamic vibration generator, and the said axis of guide passes on the moving-coil that self oiling bearing is fixed in electrodynamic vibration generator.
Compared with prior art, the advantage of the utility model is at least: 1) selflubricating guiding, and no leakage of oil hidden danger is saved cost; 2) have compensate function in the movement process, avoid stuck; 3) guiding is accurate, and lateral rigidity is high, reliable operation.
Description of drawings
Fig. 1 is the structural representation of the utility model one preferred embodiment;
The parts of each reference character and indication thereof are respectively among the figure: the axis of guide 1, self oiling bearing 2, bearing inner race 3, bearing outside 4, vulcanized rubber layer 5, ceramic material layer 6, pressure ring 7, moving-coil 8, central magnetic pole 9.
Embodiment
Be further described below in conjunction with accompanying drawing and a preferred embodiment technological scheme the utility model.
Consult Fig. 1, this selflubricating guiding device system is applied as the lower guide mechanism in the electrodynamic vibration generator, and it mainly is made up of the axis of guide 1, bearing 2, bearing inner race 3, rubber layer 5, bearing outside 4 and pressure ring 7.
Aluminum alloy axis of guide surface applying oxidn ceramic material layer 6 has increased surperficial intensity and wear resistance;
Bearing 2 adopts oil-less self-lubricating bearing, and it is to be matrix with the steel plate, the spherical bronze powder of intermediate sintering, and surface rolling teflon and plumbous mixture roll the sliding bearing that forms then;
Vulcanize rubber layer between bearing inner race 3 and the bearing outside 4, made it that certain compensation rate arranged in movement process, avoided stuck phenomenon, particularly preferred, firm in order to make the vulcanization of rubber, on bearing inner race 3 and/or overcoat 4, also can be processed with circular groove;
This kind axle, cover are slidingly matched and accomplish the form of guide function; Have that wear-resisting, corrosion-resistant, high-low temperature resistant (195 ℃～+ 270 ℃), lateral rigidity are high, guiding accurately and the characteristics of oil-free lubrication; And volume is little; Not having mechanicalness noise and oil leaking pollution, is guiding device under a kind of more satisfactory moving-coil.
It may be noted that and be: for the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to the utility model technological scheme and technical conceive, and these changes and distortion all should belong to the protection domain of the utility model claim.
