Description
Technical field
The utility model relates to deep groove ball bearing, especially relates to the deep groove ball bearing with integrated speed changing function for little load.
Background technique
Along with the continuous progress of science and technology, the efficiency of machinery becomes the discussion focus in boundary, particularly many with produce in main medium-sized and small enterprises, the concept of amount seems extremely important, in this case, they drop into certain cost for improving machine operational efficiency, but, the internal structure more complicated of the machine after some improvement, or outside adds various hydraulic pressure, pressure system for speed governing.If there is set of device, do not changing the speed-regulating hydraulic of the original mechanical structure of machine or non-additional external, when pressure system, the part only changing machine intimate just can reach the target of raising the efficiency, this brings huge economic benefits by giving the medium-sized and small enterprises of our country, the utility model is in order to realize this goal, magnetic flow liquid and these two kinds of intellectual materials of piezoelectric constant are combined, the electric energy utilizing the direct piezoelectric effect of piezoelectric constant to produce produces rheological effect to change the speed of machine section sometime within a cycle for magnetic flow liquid.And theoretically, whole device have reaction rapidly, continuously, reversible, shear yield stress is high, consume energy the feature such as low.
Model utility content
The technical problems to be solved in the utility model is to provide the deep groove ball bearing with integrated speed changing function for little load.
In order to effectively realize function as above, the utility model realizes as follows: this device is mainly by outer ring, and rolling element, retainer, inner ring, magnetic flow liquid, cage ring, electromagnetic coil, piezoelectric constant, insulator forms.Outer ring inwall has two annular grooves, and one of them annular groove is wound with electromagnetic coil, and another annular groove installs piezoelectric constant, and is isolated in outer ring and piezoelectric constant with insulator; Inner ring, outer ring and cage ring form a seal chamber, and magnetic flow liquid is sealed in wherein, and magnetic flow liquid and electromagnetic coil are isolated by cage ring; Interior ring outer wall is provided with an other than ring type small boss, installs and makes small boss do periodic motion in the annular groove that piezoelectric constant is housed, and ensure that small boss and piezoelectric constant collide once within a cycle of motion; A passage is had between electromagnetic coil and piezoelectric constant, and with two wires by piezoelectric constant both positive and negative polarity and the conducting of electromagnetic coil two ends.
When external motive force excitation machine runs, pushing shaft is forwarded dynamic, in the one-period that bearing rotates, small boss on interior ring outer wall and piezoelectric constant collide, make piezoelectric constant generation mechanically deformation, voltage is produced in piezoelectric constant two-stage, by wire, electromagnetic coil is energized, magnetic field is produced around it, make magnetic flow liquid generation rheological phenomena, produce certain shear yield stress, the operation of this shear yield stress to whole device serves the effect of a damping force, finally carrys out the change of controlling device speed in one-period.
The good effect with the deep groove ball bearing of integrated speed changing function for little load described in the utility model is: magnetic flow liquid and these two kinds of intellectual materials of piezoelectric constant are combined, and the electric energy utilizing the direct piezoelectric effect of piezoelectric constant to produce produces rheological effect to change the speed of machine section sometime within a cycle for magnetic flow liquid.And theoretically, whole device have reaction rapidly, continuously, reversible, shear yield stress is high, consume energy the feature such as low.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram with the deep groove ball bearing of integrated speed changing function of the utility model for little load.
Fig. 2 is the axial sectional view with the deep groove ball bearing of integrated speed changing function of the utility model for little load.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Composition graphs 1 and Fig. 2, the utility model is used for the deep groove ball bearing with integrated speed changing function of little load, and this device is mainly made up of outer ring 1, rolling element 2, retainer 3, inner ring 4, magnetic flow liquid 5, cage ring 6, electromagnetic coil 7, piezoelectric constant 11, insulator 12.Outer ring 1 inwall has two annular grooves, and one of them annular groove is wound with electromagnetic coil 7, and another annular groove 10 installs piezoelectric constant 11, and outer ring 1 and piezoelectric constant 11 is isolated with insulator 12; Inner ring 1, outer ring 4 and cage ring 6 form a seal chamber, and magnetic flow liquid 5 is sealed in wherein, and magnetic flow liquid 5 and electromagnetic coil 7 are isolated by cage ring 6; As shown in Figure 2, inner ring 4 outer wall is provided with an other than ring type small boss 9, installs and makes small boss 9 do periodic motion in the annular groove 10 that piezoelectric constant 11 is housed, and ensures that small boss 9 and piezoelectric constant 11 collide once within a cycle of motion; A passage 13 is had between electromagnetic coil 7 and piezoelectric constant 11, and with two wires by piezoelectric constant 11 both positive and negative polarity and electromagnetic coil 7 two ends conducting.
This device combines magnetic flow liquid 5 and these two kinds of intellectual materials of piezoelectric constant 11, and the electric energy utilizing the direct piezoelectric effect of piezoelectric constant 11 to produce produces rheological effect to change the speed of machine section sometime within a cycle for magnetic flow liquid 5.And theoretically, whole device have reaction rapidly, continuously, reversible, shear yield stress is high, consume energy the feature such as low.
When external motive force excitation machine runs, pushing shaft is forwarded dynamic, in the one-period that bearing rotates, small boss 9 on inner ring 4 outer wall collides with piezoelectric constant 11, make piezoelectric constant 11 that mechanically deformation occur, voltage is produced in piezoelectric constant 11 two-stage, by wire, electromagnetic coil 7 is energized, magnetic field 8 is produced around it, make magnetic flow liquid 5 that rheological phenomena occur, produce certain shear yield stress, the operation of this shear yield stress to whole device serves the effect of a damping force, finally carrys out the change of controlling device speed in one-period.
