Description

For the cylindrical roller thrust bearing with integrated speed changing function of little load

Technical field

The present invention relates to cylindrical roller thrust bearing, especially relate to the cylindrical roller thrust 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 cylindrical roller thrust 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 blowout patche, and seat ring, rolling element, retainer, magnetic flow liquid, electromagnetic coil, cage ring, piezoelectric constant, insulator forms.Seat ring upper surface has two annular grooves, and one of them annular groove is wound with electromagnetic coil, and another annular groove installs piezoelectric constant, and seat ring and piezoelectric constant is isolated with insulator; Blowout patche, seat ring and cage ring form a seal chamber, and magnetic flow liquid is sealed in wherein, and itself and electromagnetic coil are isolated by cage ring; Blowout patche lower surface 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 blowout patche lower surface 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 cylindrical roller thrust 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.

Fig. 1 is the structural principle schematic diagram with the cylindrical roller thrust bearing of integrated speed changing function of the present invention for little load.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in more detail.
