Description
Technical field
The utility model relates to tapered roller thrust bearing, especially relates to the tapered roller thrust bearing with integrated damper based on magnetic rheology effect.
Background technique
Tapered roller thrust bearing is a kind of very important component in contemporary machinery, and wherein the major function of tapered roller thrust bearing bears thrust load, supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.It is made up of blowout patche, seat ring, tapered roller.Requiring to bear very heavy thrust load, and impact loading is insensitive, and need by tapered roller thrust bearing in the equipment supporting running under the high occasion of rigid requirements, 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, the component and seeming changed in the brake system of machine also will often be gone to bother very much.Therefore, the various 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 tapered roller thrust bearing based on magnetic rheology effect all over the body.
In order to effectively obtain this tapered roller thrust bearing with integrated damper based on magnetic rheology effect, the utility model realizes as follows: this device is by cage ring, sealing axle sleeve, blowout patche, magnetic flow liquid, field coil, tapered roller, coupling frame, seat ring forms.Described blowout patche, seat ring, sealing axle sleeve and cage ring form a movable closed chamber, and magnetic flow liquid is sealed in inside closed chamber.Described seat ring symmetry has groove, and field coil inside groove, and has cage ring magnetic flow liquid and field coil to be isolated.The spindle nose stretching into blowout patche and seat ring when described blowout patche, seat ring, sealing axle sleeve and this bearing working forms another movable sealing room, and tapered roller and coupling frame 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 blowout patche, seat 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, bearing blowout patche constantly does cutting magnetic field motion, serves the effect hindering blowout patche 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.
The good effect with the tapered roller thrust 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 tapered roller thrust bearing, thus to reach collection damper and support function be novel tapered roller thrust 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 needs 5-8mL, and closely, rapidly, reliability is high, low cost in response for the structure of whole device.
Accompanying drawing explanation
Figure is the tapered roller thrust bearing internal structure schematic diagram with integrated damper of the utility model based on magnetic rheology effect.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In the drawings, the utility model is based on the tapered roller thrust bearing with integrated damper of magnetic rheology effect, and its internal structure is mainly made up of cage ring 1, sealing axle sleeve 2, blowout patche 3, magnetic flow liquid 4, field coil 5, tapered roller 6, coupling frame 7, seat ring 8.The blowout patche 3 of this device, seat ring 8, sealing axle sleeve 2 and cage ring 1 form a movable closed chamber, and magnetic flow liquid 4 is sealed in inside closed chamber; Seat ring 8 symmetry has groove, and field coil 5 inside groove, and has cage ring 1 magnetic flow liquid 4 and field coil 5 to be isolated; The spindle nose stretching into blowout patche 3 and seat ring 8 when blowout patche 3, seat ring 8, sealing axle sleeve 2 and this bearing working forms another movable sealing room, and tapered roller 6 and coupling frame 7 are arranged on inside this closed chamber.When field coil 5 is energized, magnetic confining field 9 is produced between blowout patche 3, seat ring 8, magnetic flow liquid 4, magnetic flow liquid 4 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, blowout patche 3 constantly does cutting magnetic confining field 9 and moves, and serves the effect hindering blowout patche 3 to move.In addition, according to the change of the environment of bearing working, by regulating the size of field coil 5 electric current, thus the intensity that rheological phenomena occurs change magnetic flow liquid 5 controls damping force in real time.Therefore, the novel function being not only integrated with damper and spring bearing of this use, but also intelligent control can be carried out to damping force.
When bearing working, field coil 5 is energized, closed magnetic path 9 is produced between blowout patche 3, seat ring 8, magnetic flow liquid 4, magnetic flow liquid 4 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 4 arranges chaining along magnetic direction, because blowout patche 3 operationally constantly does cutting magnetic field motion, therefore, the ferromagnetic particle of these arrangement chainings constantly hinders the rotation of blowout patche 3, serves the effect of brake.Blowout patche 3 stops operating, and field coil 5 power-off, magnetic flow liquid 4 reverts to again the Newtonian fluid of low viscosity, high fluidity.
