Abstract
The invention discloses an eccentric device with the amplitude automatically adjusted along with the rotation speed. The eccentric device comprises a liquid storage portion located at the center of the eccentric device, and eccentric portions located at the two ends of the eccentric device. The liquid storage portion is connected with the eccentric portions through liquid conveying channels, the widths of the liquid conveying channels are different, the lower portions of the liquid conveying channels are oblique planes, and the angles of all oblique planes are different. The eccentric device has the advantages that the amplitude of the eccentric device can be automatically adjusted through inertia forces along with changes of the rotation speed, and therefore the eccentric device can be widely applied to the field of machinery, medicine, communication and the like, and has wide market application prospects.
Description
Technical field
The present invention relates to mechanical field, is a kind of eccentric that automatically can adjust amplitude with rotating speed specifically.
Background technology
Existing eccentric structure is comparatively simple, utilizes the bias that asymmetric revolution produces often.Because this asymmetric amount is fixing, therefore, regardless of rotating speed height, amplitude is identical.Similar patent, what as Chinese Patent Application No.: 200510000074.6, name was called " eccentric block " patent discloses " a kind of eccentric block; its gyroaxis and center of gravity disalignment; it is characterized in that: the local, inside of eccentric block is for cavity, and profile be circle, and its gyroaxis is coaxial with the center of circle." patent of similar structures is many in addition, their common feature is amplitude and fixes; Such structure cannot meet the occasion that some needs carry out amplitude adjustment, as automatic massage machine medically, often needs the adjustment carrying out amplitude according to different positions.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of eccentric automatically adjusting amplitude with rotating speed, concrete structure is as follows:
Automatically adjust an eccentric for amplitude with rotating speed, comprise the liquid storing part being positioned at eccentric center, be positioned at the eccentric part at eccentric two ends, described liquid storing part is connected by infusion channel with described eccentric part, and each infusion channel width is different.
Be inclined-plane below described infusion channel, the angle on each inclined-plane is different.
Advantage of the present invention is: with the change of speed, can utilize the size of inertia force, and the amplitude of adjustment eccentric, like this, can be widely used in the fields such as machinery, medical science, communication, have market application foreground widely automatically.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1;
In figure, 1 is eccentric part one, and 2 for cutting off, and 3 is eccentric part two, and 4 is liquid storing part, and 5 is infusion channel one, and 6 is infusion channel two, and 51 is infusion channel one inclined-plane, and 61 is infusion channel two inclined-plane.
Detailed description of the invention
Illustrate the present invention below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the present invention includes the liquid storing part 4 being positioned at eccentric center, be positioned at eccentric part 1 and the eccentric part 23 at eccentric two ends, eccentric part 1 and eccentric part 23 are separated by partition 2; Described liquid storing part 4 is connected by infusion channel 1 with described eccentric part 1, and described liquid storing part 4 is connected by infusion channel 26 with described eccentric part 23, and infusion channel 1 is different from infusion channel 26 channel width; Like this, under same rotating speed, flow into eccentric part 1 from liquid storing part 4 different with the amount of fluid of eccentric part 23, play wobbler action.Because speed is different, the amount of fluid of outflow is also different, can with the discharge of the automatic rearrange liquids of speed, and discharge number, determine the size of eccentric force, and then determine varying in size of amplitude.
For ensureing the difference of liquid outflow amount further, thus ensure the difference of amplitude and vibration force, be inclined-plane below infusion channel, the angle on each inclined-plane is different from the angle of horizontal plane.
Described liquid preferably adopts the material that density is larger, as mercury.
Eccentric of the present invention should be a hermetically-sealed construction to ensure that liquid is not thrown out of, and is known ordinary construction, does not repeat them here as concrete hermetically-sealed construction.
Principle of the present invention is: liquid flows to the eccentric part at two ends from liquid storing part under the driving of centrifugal force, because infusion channel width is different, so the liquid weight flowing to eccentric part is also different, produces eccentric moment thus; Along with the difference of rotating speed, the weight difference of eccentric part is also different, so eccentric moment is also different; The inclined-plane of the bottom of infusion channel adds the difference of this flow on the one hand, and on the other hand, when ensureing that eccentric is static, liquid flows back to liquid storing part.
The present invention can be applied to electricity field, utilizes the flow direction of conducting liquid and the resistance value difference caused by flow difference, can be used for monitoring rotation speed etc.
Claims (2)
1. one kind adjusts the eccentric of amplitude automatically with rotating speed, it is characterized in that: comprise the liquid storing part being positioned at eccentric center, be positioned at the eccentric part at eccentric two ends, described liquid storing part is connected by infusion channel with described eccentric part, and each infusion channel width is different.
2. eccentric according to claim 1, is characterized in that: be inclined-plane below described infusion channel, and the angle on each inclined-plane is different.
