Next sees figures.1.and.2 and describes the setting of angular position adjusting mechanism 5.According to the basic configuration of the angular position adjusting mechanism 5 of present embodiment, similar to known regulating mechanism, constitute by internal-gear and external tooth gear in conjunction with the heart that differs from one another.In other words, angular position adjusting mechanism 5 has: fixed support 3, its means of fixation are installed on the framework 12a (fixed block) of cushion 12; And swinging mounting 2, it is supported by this fixed support 3 rotary way, and, be applied in the example of back device of seat 50 at angular position adjusting mechanism 5, swinging mounting 2 means of fixation are installed on the framework 11a (displaceable member) of backrest 11.Internal-gear 31 is formed in the fixed support 3, and external tooth gear 21 is formed in the swinging mounting 2.The number of teeth of external tooth gear 21 is set at than the number of teeth of internal-gear 31 lacks at least one.Incidentally, in the present embodiment in being shown in Fig. 1, the number of teeth of internal-gear 31 is set at 34, and the number of teeth of external tooth gear 21 is set at 33.Utilize so-called half method for die cutting (half-die-cutting method), by press process, at the thickness direction of swinging mounting 2, only about half of or about 1/3rd with its thickness is pressed in swinging mounting 2, forms external tooth gear 21.By this half die-cut method, on swinging mounting 2, in the outer radius portion of formed projection, form external tooth gear 21 like this.Utilize so-called half die-cut method,,, be pressed in fixed support 3 to about 2/3rds, form internal-gear 31 with the only about half of of its thickness at the thickness direction of fixed support 3 by press process.By this half die-cut method, internal-gear 31 is formed in the inner-diameter portion whose of formed recess part on the fixed support 3 like this.Incidentally, this mechanism also can form like this, makes external tooth gear 21 be formed in the fixed support 3, and internal-gear 31 then is formed in the swinging mounting 2.
In such a way,, form the cylinder-shaped sleeve 3a of portion, it is protruded from internal-gear 31 along its central axis 31a at the core of internal-gear 31.In such a way, axostylus axostyle 43 is arranged in the endoporus of shaft sleeve part 3a, makes axostylus axostyle 43 pass shaft sleeve part 3a.Interlocking part 46 is connected with axostylus axostyle 43, and interlocking part 46 is used to make axostylus axostyle 43 and the angular position adjusting mechanism (not shown) interlocking that is installed on seat 10 reverse side.
First keeps support 35 to be installed on the bottom (being shown in the bottom among Fig. 2) of fixed support 3.Second keeps support 25 to be installed on the top (being shown in the top among Fig. 2) of swinging mounting 2.Axostylus axostyle 43 axially on, the top of fixed support 3 (being shown in the top among Fig. 2) is rotated support 2 and second and keeps support to be clipped in therebetween.Axostylus axostyle 43 axially on, the bottom of swinging mounting 2 (being shown in the bottom among Fig. 2) support 3 and first that is fixed keeps support 35 to be clipped in therebetween.Therefore, swinging mounting 2 and fixed support 3 are bonded to each other, and make external tooth gear 21 be meshed with internal-gear 31, can adjust the angular orientation of swinging mounting 2 relative fixed supports 3 simultaneously.
Below, the backlash regulating mechanism 4 that is arranged between internal-gear 31 and the external tooth gear 21 is described.
Backlash regulating mechanism 4 has paired wedge 41 and has spring part 42, is arranged in the gap between hole wall part 2b and the shaft sleeve part 3a.Shaping wedge like this 41 makes the thickness on its top greater than the thickness of its underpart, and under state as shown in Figure 1, the thickness that makes wedge 41 from its top to its bottom attenuation.Paired wedge 41 is arranged on the external diameter of shaft sleeve part 3a in such a way, so that wedge 41 is separated from each other at its top and bottom, as shown in Figure 1.Spring part 42 is installed in such a way, active force is applied on the spacing direction between paired wedge 41 tops, with pushing wedge 41, makes each wedge 41 be pressed against shaft sleeve part 3a and hole wall part 2b.As shown in Figure 1, this mechanism is set like this, make the active force generation effect of spring part 42, therefore and push wedge 41 and make it be resisted against shaft sleeve part 3a and hole wall part 2b, thereby and make wedge 41 move to its lower side around shaft sleeve part 3a, thereby, the relative shaft sleeve part 3a of hole wall part 2b is upwards risen, as shown in Figure 1.Therefore, hole wall part 2b upwards promotes, and makes the off-centre of center 31a of the relative internal-gear 31 of center 21a of external tooth gear 21 increase.This mechanism so is set, makes the backup each other in such a way of external tooth gear 21 and internal-gear 31, with the gap between the tooth of the tooth of eliminating external tooth gear 21 and internal-gear 31, that is the elimination backlash.
Backlash mechanism 4 has ratchet part 44, ratchet part 44 and the center that axostylus axostyle 43 rotates is separated, and form with axostylus axostyle 43 integral way.The central axis that the end parts parallel of ratchet part 44 is rotated in axostylus axostyle 43 and extending, and the end of ratchet part 44 is inserted between the bottom of paired wedge 41.Axostylus axostyle 43 extends, and makes its end protrude towards the horizontal side of angular position adjusting mechanism 5, and makes Joystick 47 means of fixation be installed in the end of axostylus axostyle 43.
When rotating, the manipulation handle 47 by this way, make ratchet part 44 lean the bottom part of one of wedge 41.When the active force that overcomes spring part 42, when wedge 41 was risen, the distance between the center 21a of external tooth gear 21 and the center 31a of internal-gear 31 reduced.Therefore, unclamp two engagements between the gear, make backlash increase.The increase of backlash makes can carry out the rotation of two gears with less engagement resistance.
When the operation of rotating Joystick 47 was proceeded, the center 21a of external tooth gear 21 moved around the center of internal-gear 31 31a.The position that makes paired wedge 41 is from the position transfer shown in Fig. 1.Therefore, shift in turn the engaging position that the tooth of external tooth gear 21 and internal-gear 31 is engaged with each other.Joystick 47 rotates a circle, causes the position relative fixed support 3 of swinging mounting 2 to shift several angle, and this angle is corresponding with the angular pitch of gear.Therefore, this mechanism can adjust the angular orientation between fixed support 3 and the swinging mounting 2.
Below, with reference to Fig. 3 and Fig. 4, being described in the internal-gear 31 of setting in the angular position adjusting mechanism 5 and the profile of tooth of external tooth gear 21, this profile of tooth forms by adopting trochoid curves.
As shown in Figure 3, set basic circle 80, make it so that round 71 modes of rolling are tangent in first round surely 71 inside surely along first.When set basic point 70 within basic circle 80, the track of basic point 70 is cycloidal curves 74 first time.Cycloidal curve 74 has loop line 74a for the first time.Set second in such a way and justify 81 surely, it is tangent that it is justified in 71 surely first, tangent and along second surely round 81 when rolling in second round surely 81 when basic circle 80, the track of basic point 70 is trochoid curves 84 (cycloidal curves 84 second time), and it has loop line 84a similarly.
As shown in Figure 4, the profile of tooth of internal-gear 31 and external tooth gear 21 forms according to loop line 74a and 84a respectively.In other words, the flank of tooth of internal-gear 31 is set in the place apart from loop line 74a constant distance A, and the flank of tooth of external tooth gear 21 is set in the place apart from loop shape 84a constant distance A.Internal-gear 31 is engaged with each other with external tooth gear 21, makes its flank of tooth that forms by this way lean each other at a plurality of contact points M place.Line of contact connects contact points M, by almost extending along the direction of the inner circumference of internal-gear 31 with along the excircle direction of external tooth gear 21 is crooked.Therefore, compare with the situation of common internal-gear and external tooth gear, can obtain the contact points M of larger amt, common internal-gear and external tooth gear have the profile of tooth that constitutes by for example involute curve, and line of contact is a straight line therein.Therefore, contact gear ratio is increased, contact gear ratio is that the quantity by the contact points that occurs whenever rotating a circle averages and obtains.Thereby, can realize joggled strength higher between the gear.
As shown in Figure 4, set the tooth of external tooth gear 21 in such a way, make it have predetermined tooth depth.A kind of curved surface R1 is applied to corner part, and this corner part is as the Topland 22 of each tooth and the boundary between the side 23.Another kind of curved surface R3 is applied to its tooth bottom surface (bottom land).On the other hand, the corner part of another kind of curved surface R3 (should be R2) as the Topland 32 of internal-gear 31 is set.Therefore, the internal-gear 31 that is shaped like this makes internal-gear 31 and external tooth gear 21 be engaged with each other and when rotating, can not cause the tooth of internal-gear 31 and external tooth gear 21 to influence each other.For the pressing mold (press die) in the half die-cut method that adopts press process, need the shape of each curved surface R1, R2 and R3.By setting these curved surfaces R1, R2 and R3, guarantee the serviceability of pressing mold.External tooth gear 21 is provided with flank of tooth part (relief flank part (relief flank portion)) 24, be similar to curved surface R1 and the R2 and the Topland 22 of profile of tooth, this flank of tooth part 24 is different with trochoid curves, but form in such a way, so that load is unloaded on the flank that is not adjacent to each other from the related side 23 and 33 of adjacent teeth.Therefore, external tooth gear 21 is set like this, the position C (Fig. 4) that makes at the top dead center of engaging gear locates, and gear does not take place lean each other.Therefore, contact points M is arranged as makes on its both lateral sides that is dispersed in top dead center C position.Adopting the gear that forms in such a way so that it has under the situation of this configuration,, also making load be scattered in many teeth of a plurality of contact points M, rather than concentrating on the tooth of position of top dead center C even when in profile of tooth, form error occurring.Incidentally, also this mechanism can be set like this, make curved surface R3 be applied to the tooth bottom surface of each tooth of external tooth gear 21, and make internal-gear 31 have flank of tooth part 24.
Revise gear like this according to loop line 74a and 84a formation profile of tooth, make the Topland to approach the tooth bottom surface of external tooth gear 21 each tooth more and to approach internal-gear 31 each tooth more, the side 23 of external tooth gear (21) and the side 33 of internal-gear 31 is approaching more radially bends.Like this, as shown in the left part of Fig. 4, in position away from top dead center C place, at contact points M place, the flank of tooth F of each external tooth gear 21 and internal-gear 31, with respect to the perpendicular plane E of the sense of rotation of external tooth gear, flank of tooth F is less to the inclination angle D of plane E.Therefore, Pei Zhi mechanism like this, easier assurance opposing is applied to the intensity of the load of its sense of rotation.
In aforementioned embodiments, the profile of tooth of internal-gear 31 and external tooth gear 21 is formed by the point that is positioned at from loop line 74a and 84a constant distance A, although be on such profile of tooth, to set the flank of tooth, also the flank of tooth can be set in from relative loop line 74a of internal-gear 31 and 84a and distinguish the position of lateral shift at a predetermined angle with external tooth gear 21 sense of rotation separately.
As mentioned above, by half method for die cutting such as working pressure moulding, in swinging mounting 2 and fixed support 3, form internal-gear 31 and external tooth gear 21.Which kind of method that don't work by using the trochoid curves by the theoretical expression strict difinition, and is used numerical control machine tool, can make the shaping die with good accuracy.According to have a mind to using a kind of like this theoretical expression, can be accurately and easily set the tooth intensity of gear.
With reference to Fig. 5, a kind of profile of tooth according to second mode of execution is shown here, it can be applicable to adjust structure 5 according to angular orientation of the present invention.In being shown in the mode of execution of Fig. 5, the circle with minimum diameter is set at decides circle 180.Change present embodiment, make the inner circumference of basic circle 171 and 181 and round 180 cylindrical phase inscribe surely.Basic point 170 moved and the trochoid curves 174 and 184 drawn when acquisition was rolled basic circle 171 and 181.In this case, decide on the diametric(al) of circle and basic circle, on the orientation of the opposite orientation that becomes ring with loop line 74a that makes first mode of execution and 84a, form loop line (174a and 184a) at each.Have external tooth gear 121 and internal-gear 131 according to trochoid curves 174 and 184 resulting profiles of tooth respectively, it is applied in the angular position adjusting mechanism 5, the external tooth gear and the internal-gear that can be similar to first mode of execution are handled.
