According to the characteristics that a motion trail of a short shaft on a driving disc relative to a driven disc is a circle when the driving disc is in synchronous eccentric rotation with the driven disc, a mechanism which can be used for restraining the short shaft to move on the circular movement trail is arranged on the driven disc, and the driving disc can be in synchronous rotation with the eccentric driven disc. The eccentric synchronous transmission device can be used for eccentric shaft coupling and eccentric transmission in a narrow and small space and, and has the advantages of simple and firm structure, stable and reliable transmission and the like.
Description
One, technical field: the present invention relates to mechanical transmission, especially relevant with eccentric gearing.
Two, background technique: known Synchronous Transmission technology is more, and universal joint is arranged, and gear etc. is also arranged, if but the distance between the rotating disk of two bias is very little, and universal joint just can't use, if peripheral space is very little again, gear has also just been installed nowhere.
Three, summary of the invention: task of the present invention is to provide and a kind ofly can makes two parallel and eccentric rotating disks, the device that carries out transmission when little spacing to almost contact.
In order to complete above-mentioned task, solution of the present invention is: on a card in two mutual eccentric rotating disks of installing, a minor axis is installed, and this minor axis is just in time contacted with the card of another rotating disk, when these two rotating disks are done synchronous the rotation, the minor axis of installing on turntable surface, can stay the movement locus of minor axis on another turntable surface, this track is a circle, as long as minor axis can only be moved on this circle track all the time, these two the eccentric rotating disks of installing will synchronously rotate so.
The mechanism that above-mentioned restriction minor axis moves on circular trace, the present invention is referred to as circular mechanism, obvious circular mechanism can have multiple, the present invention exemplifies two kinds here: the first is circular round and smooth groove, with the circular trace that the minor axis on rotating disk is done, scribe into the round and smooth groove that width can hold the circle that minor axis is free to slide, then minor axis is stretched into wherein, outside circular round and smooth groove, the rotating disk of these two bias will synchronously not rotate as long as minor axis is not dished out.Because the circular trace that minor axis is done on rotating disk is synchronously rotated as prerequisite take two rotating disks.The mechanism that the restriction minor axis here moves on circular trace is circular round and smooth groove, so the circular mechanism here is round and smooth groove.The second is common crank, the rotating minor axis of installing on one end of crank and rotating disk is connected, and the other end is rotatably mounted on the home position of the circular trace that the minor axis on another rotating disk does, the circle that crank is rotated a circle do, just in time consistent with the circular trace that former minor axis is done.With crank connect between two mutual eccentric rotating disks this moment, is whichsoever that driving disc rotates, and another will led by crank and rotate.The circular mechanism here is comprised of the circular hole that crank rotatably is installed on crank and rotating disk.
For convenience of description, the present invention is with above-mentioned minor axis and round and smooth groove, and the compatibility of this eccentric gearing parts of minor axis and crank and circular hole, be called the eccentric gearing pair, a minor axis and a round and smooth groove compatibility, just become an eccentric gearing pair, two such minor axises and two round and smooth groove compatibilities are two eccentric gearing pairs, in like manner, the compatibility of minor axis and crank and circular hole (be used for installing crank) is also an eccentric gearing pair.
Above-mentioned circular mechanism has multiple, yet can there be multiple variation in every kind of circular mechanism again, as roller can be installed on minor axis, simultaneously round and smooth groove is widened to and can holds roller free rolling width, so just the slip with original minor axis has made rolling into, has reduced wearing and tearing.Moreover, can also be between two rotating disks several minor axises and roller and the such transmissions of round and smooth groove installed rely on the interaction between a plurality of transmissions more, can save the inwall of round and smooth groove and become a circular groove.Similarly crank also can have multiple variation, increase as the diameter with crank rotatable end on rotating disk, increase to radius and surpass former crank itself, circular hole with the installation crank on rotating disk also correspondingly increases simultaneously, due to the not increase of minor axis this moment, so original crank has just become an eccentric wheel.Obviously this transmission compatibility of minor axis and eccentric wheel and circular hole, be also an eccentric gearing pair.
In addition, reason due to Practical manufacturing, if between the rotating disk of two bias, only with a minor axis and a round and smooth groove, so when minor axis to the direction of the active force of round and smooth groove during near the tangent direction of minor axis movement locus, the synchronous rotation meeting of two rotating disks is because of the gap between minor axis and round and smooth groove, and the generation error.Therefore, often need to two or more eccentric gearings be installed at (at least not on same diameter) on the different amount of two rotating disks secondary, with the synchronous rotation that guarantees two rotating disks seldom or there is no an error.
Four, description of drawings:
Fig. 1 is the first embodiment of the present invention, has the radial gear schematic diagram of the round and smooth groove transmission of minor axis.
Fig. 2 is the second embodiment of the present invention, has the radial gear schematic diagram of a plurality of eccentric gearing parafacies mutual effect.
Fig. 3 is that the circular mechanism of the third embodiment of the present invention is the radial gear schematic diagram of crank and circular hole.
Fig. 4 is that the circular mechanism of the fourth embodiment of the present invention is the radial gear schematic diagram of eccentric wheel and circular hole.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Five, embodiment:
Fig. 1 is that a circular mechanism (5) is the radial gear schematic diagram of round and smooth groove (4), for convenience of explanation, the present invention has been drawn as the cross sample with a rotating disk, be referred to as cross plate (1), and another rotating disk that is still circle is called circular discs (2), simultaneously minor axis (3) is installed on cross plate (1) upper (all minor axis is installed on cross plate later on and describes), round and smooth groove (4) is engraved on circular discs (2), one end of the upper minor axis (3) of installing of cross plate (1) stretches in round and smooth groove (5) on circular discs (2), because synchronize when rotating with circular discs (2) when cross plate (1), the track that minor axis (3) is done is exactly the circle of round and smooth groove (4), therefore, if cross plate (1) is driving disc, the minor axis on it (3) can be stirred circular discs (2) along round and smooth groove (4) limit sliding edge and does synchronously to rotate, if circular discs (2) is driving disc, minor axis (3) can be along round and smooth groove (4) slip and by round and smooth groove (4) with making cross plate (1) do synchronous rotation.The round and smooth groove (4) here is the mechanism that assurance minor axis (3) is made circular movement, and the present invention is called circular mechanism (5).Cross plate (1) and circular discs (2) are to rely on the interaction of minor axis (3) and circular mechanism (5) and realize eccentric gearing, the present invention with this transmission collocation of minor axis (3) with circular mechanism (5), is called eccentric gearing pair (6) for this reason.
Be not difficult to find out from Fig. 1, in the transmission of power of cross plate (1) and circular discs (2), be arranged in two eccentric gearing pairs (6) on the figure X-axis because of the power transmission direction of minor axis (3) tangent direction near minor axis (3) movement locus, due to gapped between minor axis (3) and round and smooth groove (4), if there is no the eccentric gearing secondary (6) on Y-axis, the Synchronous Transmission between cross plate (1) and circular discs (2) will have error, causes the inhomogeneous, asynchronous of rotating speed.Therefore two (two time can not on a diameter) or above eccentric gearing to be installed secondary on the different radial angles between cross plate (1) and circular discs (2), guarantee eccentric gearing synchronous accurate.
As Fig. 2, Fig. 2 is the radial gear schematic diagram that roller (7) have been installed on minor axis (3) in Fig. 1, substitutes the slip of minor axis (3) with the rolling of roller (7), can reduce wear; Round and smooth groove (4) in figure is because having used the interaction of a plurality of eccentric gearings secondary (6), the inner ring slide wall that has removed round and smooth groove (4) forms a circular groove, but describe for unified, will it be called round and smooth groove (4), the working principle of Fig. 2 is identical with Fig. 1, has repeated no more here.
As Fig. 3, the circular hole (9) of the crank in Fig. 3 (8) and the installation on circular discs (2) is to limit the circular mechanism (5) that minor axis (3) is made circular movement, and it is just in time consistent with the circular trace that minor axis (3) is done that the crank (8) on circular discs (2) rotates the circle of doing in a week.One end of crank (8) is connected with minor axis (3) and (in fact has been made for one, but distinguished for the needs that illustrate), the other end of crank (8) is rotatably installed in circular hole (9) on circular discs (2), is connected with crank between the eccentric cross plate (1) of installing and circular discs (2).Obviously, be whichsoever the active dial rotation, another crank that must be connected is each other leading and is rotating.
As Fig. 4, in order to clearly show eccentric wheel (10), Fig. 4 divide done the up and down two-part, first figure has installed eccentric wheel (10) on minor axis (3) on cross plate (1), second figure be circular discs (2) on the position corresponding to eccentric wheel (10), beaten circular hole (9).Then first figure and second figure are combined, namely become a radial gear.The eccentric wheel here (10) can be regarded as crank (8) and increases at the diameter of the mounting end of circular discs (2), become and be eccentric wheel (10), and make eccentric wheel (10) rotate a week, drive the circle that minor axis (3) turns over, just in time synchronize when rotating with cross plate (1) and circular discs (2), the movement locus of minor axis (3) on circular discs (2) is consistent.The operation process of Fig. 4 has no longer described in detail here.
In sum, circular mechanism not only has multiple, and every kind have different variations, so the present invention can't exemplify one by one.
