For ease of understanding, this paper only is arranged on the friction pair 2 that is formed by eccentric wheel 5 and the shaft shoulder 31 as example and describes take tapering element 1, please refer to Fig. 7-11.But this can not be interpreted as that tapering element 1 of the present invention only can be arranged between eccentric wheel 5 and the shaft shoulder 31; When tapering element 1 is arranged on other friction pairs 2, can arrange with reference to its structure between eccentric wheel 5 and the shaft shoulder 31.
Please further with reference to Figure 12, Figure 12 dissects the local enlarged diagram figure of rear eccentric wheel and shaft shoulder part along the C-C direction in Fig. 8.
Under normal circumstances, between eccentric wheel 5 and the shaft shoulder 31, substantially do not have diametrically gap, eccentric wheel 5, with the outer wall of its inner wall surrounding at the shaft shoulder 31, can be realized the face contact basically; When seat adjusts machine to adjust the angle of seat, eccentric wheel 5 is with respect to the radially outward upset of the shaft shoulder 31, and at this moment, the inwall of eccentric wheel 5 is around the curved surface outwards upset successively of the second end face 12, eccentric wheel 5 remains that with the second end face 12 face contacts or the line contact, as shown in figure 12; With respect to eccentric wheel 5 in the prior art shown in Fig. 6, with the point of the shaft shoulder 31, contact, between the eccentric wheel 5 that is provided with tapering element 1 and the shaft shoulder 31, remain that face contacts or the line contact, thereby reduced largely the rate of wear, improved the durability of eccentric wheel 5 and the shaft shoulder 31.
Can expect, on eccentric wheel 5, groove 51 can be set, groove 51 is be used to holding tapering element 1, tapering element 1 can circumferentially be fixedly attached in groove 51, when eccentric wheel 5 when the shaft shoulder 31 circumferentially rotates, can drive tapering element 1 and circumferentially rotate around the shaft shoulder 31, tapering element 1 can constantly be adjusted the relative position relation with the shaft shoulder 31, so that the first end face 11 can remain that with the outer wall of the shaft shoulder 31 face contacts or the line contact.
It will also be appreciated that, tapering element 1 can also be arranged between the inwall of eccentric wheel 5 and axle center hole 41, and can arrange at the outer face of eccentric wheel 5 groove 51 this moment, in order to hold tapering element 1; Tapering element 1 is that the first end face 11, the first end faces 11 are set to the face of cylinder identical or close with the inwall of axle center hole 41 towards the end face of the inwall of axle center hole 41, in order to be mated; Tapering element 1 is the second end face 12 towards a side end face of the outer wall of eccentric wheel 5, and this second end face 12 also is set to curved surface; During with respect to the radially outward upset of axle center hole 41, the outer wall of eccentric wheel 5 overturns successively around the curved surface of the second end face 12, remains face contact or line contact when eccentric wheel 5.
In like manner, between wedge 6 and the shaft shoulder 31, between the inwall of wedge 6 and axle center hole 41, also tapering element 1 can be set, specifically can be arranged between eccentric wheel 5 and the shaft shoulder 31 with reference to tapering element 1, the embodiment between the inwall of eccentric wheel 5 and axle center hole 41 carries out corresponding configuration, repeat no more herein.
Certainly, wedge 6 also can arrange the installation groove in its side end face towards the shaft shoulder 31, so that tapering element 1 circumferentially is fixedly mounted in, installs in groove; In addition, wedge 6 can also arrange the installation groove in the side end face towards axle center hole 41, to hold and tapering element 1 is installed.
Theoretically, on above-mentioned four friction pairs 2, all tapering element 1 can be set, but, consider the complexity of structure, usually only need be on the friction pair 2 that eccentric wheel 5 and the shaft shoulder 31 form or on the friction pair 2 that forms of the inwall of eccentric wheel 5 and axle center hole 41, a tapering element is set and gets final product, that is to say, when eccentric wheel 5 during as the second friction member 22, can tapering element 1 be set in inner friction surface or the outer friction surface of eccentric wheel 5, in order to during eccentric wheel 5 axial turning, carry out conicity regulation, without on two friction pairs 2, tapering element 1 being set all; In like manner, when wedge 6 during as the second friction member 22, in the friction pair 2 that can form at the inwall of friction pair 2 that wedge 6 and the shaft shoulder 31 form or eccentric wheel 5 and axle center hole 41, optional one arranges tapering element 1, the conicity regulation when meeting wedge 6 axial turning.
Correspondingly, in the situation that service life is enough, can only on the friction pair 2 of eccentric wheel 5 or wedge 6 formation, a tapering element 1 be set, for example between wedge 6 and the shaft shoulder 31, also the tapering element can be set between the inwall of wedge 6 and axle center hole 41, only the tapering that adapts in the chair angle adjustment process of the rotation by wedge 6 changes.
Obviously, when in above-mentioned four friction pairs 2, tapering element 1 being set all, whole seat angle adjustor is more stable in the process of angular adjustment, and the friction face of friction pair 2 can remain face contact or line contact, thereby extend seat service life, improve traveling comfort.
Please refer to Figure 13 and Figure 14, Figure 13 is the first side isometric view of a kind of set-up mode of tapering element provided by the present invention; Figure 14 is the second side isometric view of a kind of set-up mode of tapering element provided by the present invention.
Tapering element 1 of the present invention has the first end face 11 and the second end face 12, the first end faces 11 can adopt abrasion-resistant material to make, so that the friction of the inwall of opposing and the shaft shoulder 31 or axle center hole 41; The second end face 12 is curved surface, and described curved surface can be for structures such as sphere or cylinder profiles, in order to adapt to better the connection requirement of eccentric wheel 5 or wedge 6, as shown in figure 14.
Obviously, tapering element 1 of the present invention can whole adopt mechanical property preferably material make, to advance, may improve intensity, extend its service life, reduce the rate of wear.
Adopt tapering element of the present invention, can make the friction pair in seat angle adjustor be in all the time face contact or line contact, to reduce parts depreciation speed, extend the service life of seat angle adjustor and seat; On the other hand, because the contact between friction face remains face contact or line contact, seat angle adjustor can support by face or line in the process of regulating, and then the reliability of raising connection, thereby effectively prevent rocking of seat, avoid in control process producing noise, improve the traveling comfort of seat.
In addition, four friction pairs 2 mentioned above are only four friction pairs 2 more common in seat angle adjustor, when in seat angle adjustor, having other friction pairs 2, also can on other friction pairs 2, tapering element 1 be set, then the analogy said structure arranges, to reach the effect of conicity regulation, reduce the wearing and tearing of parts.
Please refer to Figure 15, Figure 15 is that tapering element provided by the present invention is arranged on the cross-sectional view on other friction pairs.
As shown in figure 15, between internal gear 3 and outer tooth plate 4, be filled with two or more friction member 7, and the area discrepancy of each friction member 7 hour, on each friction member 7, tapering element 1 can be set all, in order to realize better the adjusting of tapering, reduce the rate of wear and severe degree.
