Description
Technical field
The utility model relates to a kind of deep groove ball bearing, especially relates to a kind of deep groove ball bearing with integrated damper based on magnetic rheology effect.
Background technique
Deep groove ball bearing is a kind of very important component in contemporary machinery, and it is made up of inner ring, outer ring, retainer, steel ball, 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, bicycle 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 caused traffic accident of stepping on the gas can be found everywhere.In addition, also to often remove to change brake block and seeming to 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 deep groove ball bearing based on magnetic rheology effect all over the body.
In order to effectively obtain a kind of deep groove ball bearing with integrated damper based on magnetic rheology effect, the utility model realizes as follows: this device is by inner ring, outer ring, cage ring, retainer, steel ball, magnetic flow liquid, sealing axle sleeve, field coil 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 steel ball and retainer are arranged on inside this closed chamber.Described ball surfaces 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 original 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 deep groove ball 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 original 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 deep groove ball bearing, thus to reach collection damper and support function be novel deep groove ball bearing all over the 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 deep groove ball 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 deep groove ball bearing with integrated damper based on magnetic rheology effect of the utility model, its internal structure is made up of inner ring 1, outer ring 2, cage ring 3, retainer 4, steel ball 5, magnetic flow liquid 7, sealing axle sleeve 8, field coil 9.The inner ring 1 of this device, outer ring 2, sealing axle sleeve 8 and cage ring 3 form a movable closed chamber, and magnetic flow liquid 7 is sealed in inside closed chamber; Inner ring 1 symmetry has groove, and field coil 9 inside groove, and has cage ring 3 magnetic flow liquid 7 and field coil 9 to be isolated; Inner ring 1, outer ring 2, sealing axle sleeve 8 form another movable sealing room, and steel ball 5 and retainer 4 are arranged on inside this closed chamber.When field coil 9 is energized, closed magnetic path 6 is produced between inner ring 1, outer ring 2, magnetic flow liquid 7, magnetic flow liquid 7 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 1 constantly does cutting closed magnetic path 6 and moves, and serves the effect hindering inner ring 1 to move.In addition, according to the change of the environment of bearing working, by regulating the size of field coil 9 electric current, thus the intensity that rheological phenomena occurs change magnetic flow liquid 7 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 9 is energized, closed magnetic path 6 is produced between inner ring 1, outer ring 2, magnetic flow liquid 7, magnetic flow liquid 7 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 7 arranges chaining along magnetic direction, because inner ring 1 operationally constantly does cutting magnetic field motion, therefore, the ferromagnetic particle of these arrangement chainings constantly hinders the rotation of inner ring 1, serves the effect of brake.Inner ring 1 stops operating, field coil 9 power-off, and magnetic flow liquid 7 reverts to again the Newtonian fluid characteristic of low viscosity, high fluidity.
