Abstract
The invention relates to an angular contact ball bearing with an integrated transmission function for small load. The angular contact ball bearing is mainly used for regulating a speed distribution condition when a mechanism operates within one period under a small-load condition. The device comprises an outer ring, a rolling body, a retainer, an inner ring, a magnetorheological fluid, an isolating ring, an electromagnetic coil, piezoelectric ceramic and an insulating body, wherein two ring-shaped grooves are formed in the inner wall of the outer ring; the electromagnetic soil is wound in one ring-shaped groove; the piezoelectric ceramic is mounted in the other ring-shaped groove; the outer ring is isolated from the piezoelectric ceramic by the insulating body; the inner ring, the outer ring and the isolating ring form a sealed cavity in which the magnetorheological fluid is sealed; and the isolating ring is used for isolating the sealed cavity from the electromagnetic coil; a non-annular small boss is arranged on the outer wall of the inner ring; after being mounted, the small boss carries out periodic motion in the ring-shaped groove in which piezoelectric ceramic is contained; and a channel is formed between the electromagnetic coil and the piezoelectric ceramic for conducting positive and negative electrodes of the piezoelectric ceramic with the two ends of the electromagnetic coil.
Description
Technical field
The present invention relates to angular contact ball bearing, especially relate to the angular contact 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, when not changing speed-regulating hydraulic, the pressure system of the original mechanical structure of machine or non-additional external, 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 present invention is in order to realize this goal, 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.
Summary of the invention
The technical problem to be solved in the present invention is to provide the angular contact ball bearing with integrated speed changing function for little load.
In order to effectively realize function as above, the present invention 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 angular contact ball bearing of integrated speed changing function for little load of the present invention 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.
