Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Reference numeral is as follows:
Arbor 1, leading section 11, front end face 12, bar-shaped trough 13, groove side 14, transmission wheel 2, axle sleeve 21, positive round 3, oval 4.
As shown in Figure 1, the draw bail of wrist-watch arbor of the present invention and transmission wheel, comprise the transmission wheel 2 that plastic material makes and the wrist-watch arbor 1 made by metal material, wrist-watch arbor 1 is placed through in transmission wheel 2 axle sleeve 21, relative movement can be done in the axial direction therebetween, in described axle sleeve 21, cross sectional shape is circular, and described arbor 1 leading section 11 is the right cylinder of the bar-shaped trough 13 with the yi word pattern extended along its axis direction, this right cylinder and described axle sleeve 21 interference fit.
As shown in Fig. 3,5, described bar-shaped trough 13 for being arranged on, arbor 1 front end face 12 runs through the in-line groove of this end face, the degree of depth of groove is 0.3mm-1.2mm, be preferably 0.8mm, its width is 0.1mm-0.3mm, is preferably 0.13mm, and the groove side 14 of groove is perpendicular with this end face, arbor 1 front end face 12 can arrange one this end face is divided into two-part bar-shaped trough 13, the bar-shaped trough 13 of many mutual flat shapes also can be set.
As shown in Figure 1, when wrist-watch be in normally walk time state, arbor 1 pushes in wristwatch case, arbor 1 leading section 11 and transmission wheel 2 axle sleeve 21 are in and depart from wringing fit state (namely arbor 1 leading section 11 is placed in the aperture larger part in axle sleeve 21), even rotate the handle of arbor 1 outer end, therefore transmission wheel 2 can not rotate, and now, transmission wheel 2 axle sleeve 21 cross sectional shape is positive round 3 shape (broken circle as in Fig. 4 and Fig. 6).
As shown in Fig. 2,4,6, when outwards stirring arbor 1 to adjustment proof time position, leading section 11 and transmission wheel 2 axle sleeve 21 close-fitting of arbor 1 merge be interlocked (namely arbor 1 leading section 11 is placed in the aperture smaller part in axle sleeve 21), owing to being interference fit therebetween, transmission wheel 2 axle sleeve 21 pairs of arbor 1 leading sections 11 impose radial pressure, this radial pressure to be parallel to bar-shaped trough 13 different with perpendicular to the displacement deformation that bar-shaped trough 13 direction makes arbor 1 leading section 11 produce, is described below:
1) on the direction being parallel to bar-shaped trough 13, due to the rigid structure of arbor 1, therefore, the diameter of the party's upwards transmission wheel 2 axle sleeve 21 is forced to elongate;
2) on the direction perpendicular to bar-shaped trough 13, because bar-shaped trough 13 has certain gap, under the effect of described axle sleeve 21 plastic resilient power, the extruding force that arbor 1 leading section 11 is subject to is larger, thus the displacement deformation produced is larger, the gap of bar-shaped trough 13 also narrows thereupon, and each several part that therefore the party is formed after upwards being cut by bar-shaped trough 13 is drawn close relatively, makes front end face 12 ovalize of arbor 1.
Under the acting in conjunction of above-mentioned two situations, to be coordinated from the cylindrical interference of prior art coordinating between arbor 1 with described axle sleeve 21 and become nearly oval 4 shape interference fit of the present invention, namely Profile Connection coordinates.
It is exactly a kind of connecting mode adopting the hole axle of not rounded odd-shaped cross section to coordinate to come transmitting torque that so-called Profile Connection coordinates.Owing to structurally with in technique having unique superiority, to use and can transmitting large torque, therefore Profile Connection is engaged in various mechanical drive and is widely used.
Profile Connection coordinates can improve linking intensity greatly, can reduce manufacturing cost simultaneously, simplifies the manufacture craft of axle sleeve 21, improves the cooperation nargin of axle sleeve 21.
If arbor 1 of the present invention is made up of elastic metallic material, after minute hand regulates check and correction to complete at that time, when arbor 1 being pushed in wristwatch case state when entering normally to walk, the leading section 11 of arbor 1 is in release conditions owing to losing axle sleeve 21 to its radial pressure, now, the bar-shaped trough 13 on it recovers former state, meanwhile, axle sleeve 21 also because losing the extruding of arbor 1 leading section 11 to it, recovers virgin state under the effect of plastic resilient power.
After the leading section 11 of arbor 1 coordinates first with transmission wheel 2 axle sleeve 21, if produce deformation set, after also can not affecting, again coordinate the Profile Connection fit structure formed.
