Description
Technical field
The utility model relates to a kind of roller bearing, especially relates to a kind of roller bearing with integrated damper based on magnetic rheology effect.
Background technique
Roller bearing is a kind of very important component in contemporary machinery, and it is made up of inner ring, outer ring, retainer, cylindrical roller, and major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.Need by bearing at heavy-duty machines, automobile, lathe etc. in the equipment supporting running, need to set up braking device in addition, so not only make mechanical structure more complicated, cost increase, and the reliability of whole system reduces, by braking strength not or mistake can be found everywhere by contingency caused by switch.In addition, also often to remove the component changed in brake system and seem and bother very much.Therefore, a kind of bearing with integrated damper is worked out significant.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of compact structure, reliability is high and cost is low, thus can substitute traditional brake system, and collection brake and the support function of motion are the roller bearing based on magnetic rheology effect all over the body.
In order to effectively obtain a kind of cylindrical roller ball bearing with integrated damper based on magnetic rheology effect, the utility model realizes as follows: this device is by outer ring, inner ring, field coil, sealing axle sleeve, magnetic flow liquid, cage ring, cylindrical roller, retainer forms.Described inner ring, outer ring, sealing axle sleeve and cage ring form a movable closed chamber, and magnetic flow liquid is sealed in inside closed chamber.Described inner ring symmetry has groove, and field coil inside groove, and has cage ring magnetic flow liquid and field coil to be isolated.Described inner ring, outer ring, sealing axle sleeve form another movable sealing room, and cylindrical roller and retainer are arranged on inside this closed chamber.Described cylindrical roller surface scribbles strong NULL, and the model that magnetic flow liquid adopts Ningbo Sequoia Works Structure Monitor And Control Engineering Center Ltd to develop is the magnetic flow liquid of SG-MRF2035.
When field coil is energized, closed magnetic path is produced between inner ring, outer ring, magnetic flow liquid, magnetic flow liquid is made to change the Bingham fluid of high viscosity, lazy flow into by the Newtonian fluid of former rice low viscosity, high fluidity, when bearing working, inner ring constantly does cutting magnetic field motion, serves the effect hindering inner ring motion.In addition, according to the change of the environment of bearing working, by regulating the size of field coil electric current, thus the intensity changing magnetic flow liquid generation rheological phenomena controls damping force in real time.Therefore, this is not only integrated with the function of damper and spring bearing, but also can carry out intelligent control to damping force.
A kind of good effect with the roller bearing of integrated damper based on magnetic rheology effect described in the utility model is: utilize magnetic flow liquid rheological phenomena can occur under externally-applied magnetic field, its rheological properties can change in moment (millisecond magnitude), make magnetic flow liquid be the Bingham fluid of high viscosity, lazy flow by the New ton fluid transforms of former rice low viscosity, high fluidity, and this is the characteristic of continuous, a reversible process.Magnetic flow liquid and the device in order to trigger magnetic flow liquid generation rheological phenomena are integrated in inside roller bearing, thus reach collection damper and support function is the-novel roller bearing of body.And intelligentized control method can be carried out by the size changing field coil electric current to damping force, thus meet the job requirement of different places.The size that the optical axis holds in whole device and determining, required magnetic flow liquid volume only has 5-8mL, and closely, rapidly, reliability is high, low cost in response for the structure of whole device.
Accompanying drawing explanation
Figure is a kind of internal structure schematic diagram with the roller bearing of integrated damper based on magnetic rheology effect of the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In the drawings, a kind of roller bearing with integrated damper based on magnetic rheology effect of the utility model, its internal structure is made up of outer ring 1, inner ring 2, field coil 3, sealing axle sleeve 4, magnetic flow liquid 5, cage ring 6, cylindrical roller 7, retainer 8.The inner ring 2 of this device, outer ring 1, sealing axle sleeve 4 and cage ring 6 form a movable closed chamber, and magnetic flow liquid 5 is sealed in inside closed chamber; Inner ring 2 symmetry has groove, and field coil 3 inside groove, and has cage ring 6 magnetic flow liquid 5 and field coil 3 to be isolated; Inner ring 2, outer ring 1, sealing axle sleeve 4 form another movable sealing room, and cylindrical roller 7 and retainer 8 are arranged on inside this closed chamber.When field coil 3 is energized, closed magnetic path 9 is produced between inner ring 2, outer ring 1, magnetic flow liquid 5, magnetic flow liquid 5 is made to change the Bingham fluid of high viscosity, lazy flow into by the Newtonian fluid of original low viscosity, high fluidity, when bearing working, inner ring 2 constantly does cutting magnetic confining field 9 and moves, and serves the effect hindering inner ring 2 to move.In addition, according to the change of the environment of bearing working, by regulating the size of field coil 3 electric current, thus the intensity rice that rheological phenomena occurs change magnetic flow liquid 5 controls damping force in real time.Therefore, this is not only integrated with the function of damper and spring bearing, but also can carry out intelligent control to damping force.
When bearing working, field coil 3 is energized, closed magnetic path 9 is produced between inner ring 2, outer ring 1, magnetic flow liquid 5, magnetic flow liquid 5 is made to change the Bingham fluid of high viscosity, lazy flow into by the Newtonian fluid of original low viscosity, high fluidity, ferromagnetic particle in magnetic flow liquid 5 arranges chaining along magnetic direction, because inner ring 2 operationally constantly does cutting magnetic field motion, therefore, the ferromagnetic particle of these arrangement chainings constantly hinders the rotation of inner ring 2, serves the effect of brake.Inner ring 2 stops operating, and field coil 3 power-off, magnetic flow liquid 5 reverts to again the Newtonian fluid of low viscosity, high fluidity.
