The specific embodiment
As shown in Figure 5, replace tubes mechanism comprises wind 1, eccentric wheel 2, wobble gear 3, output gear 4, center shaft 5, wind spring 6, torsion spring 7, casing 8, wheel hub 9, pipe 10, stop bit ball 11.
As shown in Figure 3 and Figure 6, the cylindrical of eccentric wheel 2 is circular, and the center of its connecting bore (bias) deviates from the center of circle, and wind 1 is inserted in its connecting bore, thereby is fixedly connected with eccentric wheel 2.The body of wobble gear 3 is external gear, wobble gear 3 also comprises and is positioned at body shaft to a side and radial projection that radially outward protrude, radial projection is greater than the radical length of external gear in the radially outstanding length of wobble gear 3, as described later, radial projection is mainly used for coordinating with housing.Eccentric wheel 2 is inserted in the centre hole of wobble gear 3, so that the centre hole of the cylindrical of eccentric wheel 2 and wobble gear 3 coordinates, the center of the bias of eccentric wheel 2 (center of the connecting bore joined with wind) and wobble gear 3 is conllinear not, and eccentric wheel 2 can rotate in wobble gear 3.Output gear 4 comprises inner gear, the inner gear engagement of the external gear of wobble gear 3 and output gear 4, few 1 of the number of teeth of the ratio of number of teeth output gear 4 of wobble gear 3.Casing comprises left casing 12 and right casing 8, provide mounting hole 120 on left casing 12, wobble gear 3 is placed in mounting hole 120, mounting hole 120 is similar with the profile of wobble gear 3, corresponding radial projection has radial recess, the radial projection of wobble gear 3 just is arranged in radial recess accordingly, and wobble gear 3 just can not rotated relative to left casing 12 like this, but allows the swing of certain limit.The center of turn of the center of turn of eccentric wheel 2 and output gear 4 is conllinear, output gear 4 is fixed on center shaft 5, center shaft 5 supports rotationally by casing 8, wobble gear 3 and eccentric wheel 2 are positioned at mounting hole 120, by left casing 12, supported, the outside of mounting hole 120 is by small end cover 121 cappings.Center shaft 5 is connected by torsion spring 7 with wind spring 6 is inner, and wind spring 6 outer ends hook and consist of left and right two parts at wheel hub 9(, by center shaft 5, are rotatably supported) upper, pipe 10 is installed on wheel hub 9, pipe 10 ends are equipped with stop bit ball 11.As shown in Figure 5, torsion spring 7 is torsion spring preferably, and the leg of torsion spring links together, then is connected with the inner of wind spring 6.
Below in conjunction with Fig. 1 to Fig. 5, most preferred embodiment of the present utility model is described.
First, in conjunction with Figure 12 to Figure 15, the principle of tooth difference gear mechanism in previous embodiment is described, difference gear mechanism comprises eccentric wheel 2, wobble gear 3 and output gear 4, and in Figure 12 to Figure 15, casing is reduced to fixed bottom boundary.In Figure 12, the eccentric arm of eccentric wheel 2 down, is now 0 degree, in Figure 13, the eccentric arm of eccentric wheel 2 is towards a left side, eccentric wheel 2 clockwise rotates 90 degree, and in Figure 14, the eccentric arm of eccentric wheel 2 upward, eccentric wheel 2 clockwise rotates 180 degree, in Figure 15, the eccentric arm of eccentric wheel 2 is towards the right side, and eccentric wheel 2 clockwise rotates 270 degree.After eccentric wheel 2 rotates 90 degree again, complete a circle and rotate, be returned to the state shown in Figure 12.Because the rotation of wobble gear 3 is blocked by casing 12, can not rotate, can only on the eccentric arm track, do swing, cam bias is to which limit, and wobble gear is just in which limit and output gear engagement.Output gear 4 is than more than 3 teeth of wobble gear, and after wobble gear 3 finishes a circle, each tooth of the tooth on wobble gear 3 and output gear 4 mesh, and output gear 4 just has 1 tooth not mesh.The angle of this tooth is exactly the angle that output gear 4 rotates.
In conjunction with Fig. 3 to Figure 11, wind spring 6 has in the situation of pretension, clockwise rotates wind 1 simultaneously, and band movable eccentric wheel 2 rotates.Eccentric wheel 2 rotates and drives wobble gears 3 and swing, because wobble gear 3 has the projection shape to coordinate with casing 8, so wobble gear 3 can not rotate, and can only do circle swing with eccentric wheel 2.Wobble gear 3 and output gear 4 engagements, when wobble gear 3 swings, each tooth can with output gear 4 on the tooth engagement.Many 1 of the number of teeth on ratio of number of teeth wobble gear 3 on output gear 4, after eccentric wheel 2 has moved 1 circle, output gear 4 also surplus 1 tooth is not engaged to, and output gear has also just rotated the angle of this 1 tooth.The direction of rotating is consistent with the direction that wind rotates.Output gear 4 is connected with center shaft 5, and center shaft 5 is connected with wind spring 6.When output gear 4 rotates the angle of 1 tooth with center shaft 5, also just the come loose angle of 1 tooth of wind spring.After output gear 4 rotates certain number of turns, wind spring 7 just can come loose fully.If at this moment wind 1 is rotated further, center shaft 5 also is rotated further.But, under the effect of torsion spring 6, this rotates and can not continue to pass to wind spring 7.Thereby reach loosen wind spring 7 and the purpose of unlikely reverse pretension wind spring 7.After wind spring 7 loosens, wheel hub 9 does not just have the power rotated, and the user just can retube 10, and does not worry that wheel hub 9 can be rotated further.
When rotating counterclockwise wind 1, band movable eccentric wheel 2 is also done and is rotated counterclockwise, and eccentric wheel 2 rotates counterclockwise drive wabble wheel 3 and does counter-clockwise swing.After wabble wheel 3 rotates 1 circle, because more than 31 of output wheel ratio of number of teeth wabble wheels, output wheel 4 has rotated the angle of 1 tooth more with regard to conter clockwise, drive center shaft 5 and also do the angle that rotates counterclockwise 1 tooth.Center shaft 5 is connected by torsion spring 7 with wind spring 6, and the rotation of center shaft 5 has also driven the rotation of wind spring 6, thereby turns tight wind spring 6.
The folding part (as Figure 11) of wind 1, rotating shaft place has individual projection, and when wind is folding, projection just can coordinate with casing, prevents that wind from rotating; When the folding part of wind is opened, projection just no longer coordinates with casing, and wind 1 just can rotate.In the aforementioned embodiment, wind 1 can easily rotate and drive output gear 4, and output gear 4 rotates, and need to reach larger power could rotary handle crank 1.
In the aforementioned embodiment, pipe 10 can replace with cable or rope or other flexible elements.Wind 1 and eccentric wheel 2 can be made detachable.
