The eccentric unit 6 that assembles and the details of each member thereof have been shown in Fig. 2 A to Figure 12.In Fig. 2 A to Fig. 5 B, show rotation axis for regulating the eccentric component 12 being arranged on bent axle 4 offset with respect to the rotation axis of bent axle 4 with different views, in Fig. 2 A and Fig. 2 B, illustrate with three-dimensional view, wherein, eccentric component 12 has different offsets in Fig. 2 A and Fig. 2 B, in Fig. 3 A and Fig. 3 B, illustrate with front view, wherein, eccentric component 12 also has different offsets, in Fig. 4, illustrate with cross sectional view, wherein, cross section is the section plane vertical with respect to the axial direction of bent axle 4, longitudinal cross-section view with the axial direction along bent axle 4 in Fig. 5 A and Fig. 5 B illustrates, wherein, also show different offsets.
As shown in FIG., device 10 for eccentric adjustment amount has multiple eccentric unit 6 that are in succession arranged in the axial direction on bent axle 4, and described eccentric unit has eccentric component 12, wherein, eccentric unit 6 is constructed identical substantially, only an eccentric unit is described thus at this.
Especially be respectively arranged with for example ball bearing of rolling bearing 17 around the eccentric component 12 of constructing circularly generally, the connecting element 8 only schematically showing in Fig. 2 A to Fig. 4 is supporting by these rolling bearings.Also can replace rolling bearing for connecting element 8 supports by other suitable bearing.
Each eccentric component 12 is made up of two half-unit 13,14, and these half portions are by eccentric component 12 is formed in two along diametric(al) substantially.In the time being assemblied on bent axle 4, eccentric component half portion 13,14 is by being arranged on recess in these eccentric component half portions and screw thread by means of screw 15 be threaded and be bonded together (referring to Fig. 4).
Eccentric component 12 can be bearing in movably in the corresponding guiding area 18 of bent axle 4 in the plane vertical with respect to crankshaft center line.These guiding areas 18 are arranged on the eccentric region on bent axle 4, and these eccentric region are configured to chute guiding form.The bent axle 4 with corresponding guiding area 18 can be clear that from Fig. 6.In the form of implementation shown in Fig. 6, be provided with four guiding areas 18, thus, affiliated eccentric component 12 can move respectively on the guiding area 18 of correspondence configuration.Because be provided with four guiding areas 18, so these guiding areas misplace toward each other and rotate 90 ° on the circumferencial direction around crankshaft center line, thus, the movement direction of eccentric component misplaces in the direction of 90 ° and carries out on the circumferencial direction at crankshaft center line toward each other, and the offset of their own axis about bent axle 4 also misplaces, thus, the stroke arranging by each eccentric component 12 is passed to equably the driven shaft 5 of crank-CVT speed changer in the time that bent axle 4 rotates 360 ° in identical angle intervals by bent axle 4.If four above eccentric unit 6 are set, these eccentric unit are in a circumferential direction aspect its offset and can correspondingly misplace and arrange aspect its orientation, and described offset is identical about movement direction in size respectively.Especially be suitable for: guiding area 18 is axial identical far mobile about bent axle 4 from centre, there is the offset of same degree, and the 360 °/n ground setting that misplaces toward each other the in the situation that of n guiding area 18.
As from Fig. 7, can be clear that and cross section in Fig. 4 shown in, in the guiding area 18 of bent axle 4, be provided with the regulon 20 with respect to the offset of the rotation axis of bent axle 4 for the rotation axis of eccentric adjustment member 12.In cross sectional view in three-dimensional view in Fig. 9 and in Figure 10, clearly show that regulon 20.
Especially regulon 20 comprises worm gear 22, and the three-dimensional view in Figure 11 also shows this worm gear.Worm gear 22 has internal thread 24, and this internal thread extends through worm gear and is configured to self-locking thread 24 in the adjusting direction of eccentric component 12.Screw thread 24 coordinates with screw 26, and this screw is shown in Figure 12 and be bearing in corresponding eccentric component 12 to rotation inhibiting regulating in direction.Screw thread 24 forms screw device together with having its externally threaded screw 26.By rotating worm gear 22 with respect to screw 26, in bent axle 4 regulate the worm gear 22 that is immovably being supported in direction and about eccentric component 12 positions regularly screw 26 move upward in adjusting side toward each other.This makes eccentric component 12 move and change with respect to the offset of bent axle 4.
In order to make screw 26 rotation inhibiting, this screw is configured with polygonal type exterior feature, the boss 27 of rectangular parallelepiped shape in this case on two end opposite each other, and this boss is embedded in the respective recess on eccentric component and prevents that thus screw 26 from rotating.The thread structure of screw 26 become outside thread and aspect self-locking corresponding to the internal thread 24 in worm gear 22.
For by the guiding area 18 of regulon 20 supporting crankshafts 4, especially bent axle 4 for this reason arrange recess in, be provided with radial bearing 28 and cod 29, thus, worm gear 22 can be around the corresponding axis of the axis of thread of itself and screw thread 24 rotationally but be immovably supported in the axial direction.Radial bearing 28 prevents movement in the radial direction in addition, but allows mentioned rotation.For this reason, on worm gear 22, be provided with for the corresponding guiding area 30 of radial bearing 28 with for the corresponding guiding area 31 of cod 29.For worm gear 22 is installed in corresponding guiding area 18, guiding area 18 is configured with respectively the recess of contraction, and this recess allows worm gear 22 to insert from a side.Worm gear 22 is fixing by means of nut 32 together with bearing 28,29 after packing into.
In addition, be provided with tooth region 34 on worm gear 22, on this tooth region outer peripheral surface on worm gear 22 and mated to such an extent that coordinate with unshowned worm screw 40 in Figure 10, the adjusting rotational motion of worm screw 40 is introduced in worm gear 22 as rotational motion thus.
In Fig. 8 A and Fig. 8 B, show and there is the bent axle 4 of guiding area 18 and the regulon 20 packing into different three-dimensional views, including screw 26.
In addition, from position and the location that can see worm screw 40 the cross section shown in Fig. 5 A and Fig. 5 B in a longitudinal direction of bent axle 4.Worm screw 40 is encased in the hollow space 41 that is configured to axial bore, and this hollow space extends as blind hole in a longitudinal direction in the axial direction in bent axle 4.At this, the position of worm screw 40 and worm gear 22 is selected like this, and the tooth region 34 of worm gear 22 can be engaged with worm screw 40.Worm screw 40 itself to be encased in hollow space 41 and by cod 44 by needle bearing 43 rotatably supports and remains in position about axial direction.
If eccentric component 12 will change with respect to the offset of the rotation axis of bent axle 4, the rotation axis of eccentric component 12 will change with respect to the rotation axis of bent axle 4, by not shown motor or other drive unit, worm screw 40 is rotated.Worm screw 40 can not move in the axial direction owing to being axially fixed.Worm screw 40 coordinates with the worm gear 22 of regulon 20, and these regulons are placed in the guiding area 18 of bent axle 4.By the rotation of worm screw 40, worm gear 22 also rotates.Thus, make the position of regulon 20 with respect to the change in location of eccentric unit 12 by means of the screw-thread fit that is fixed on the screw 26 in eccentric component 12 and be fixed between the regulon 20 in bent axle 4.Thus, the stroke that can pass to connecting element 8 (referring to Fig. 1) changes, and this also makes the velocity ratio of speed changer 1 change.By the rotation of worm screw 40 and the resultant rotation of worm gear 22, worm gear 22 is along the axial direction of screw 26 and in the adjusting direction of eccentric unit 12, move about bent axle 4 thus.
Because the whole eccentric unit 12 that makes to be arranged on bent axle 4 by means of worm screw 40 obtains even regulation by controlling device 20 simultaneously, so do not need the synchronous device of different adjustment for making each eccentric unit 12.Screw thread 26 combines with the internal thread 24 of worm screw 22 and to be configured to self-locking, thus, be used in the governor motor that worm screw 40 rotates and be not energized, each eccentric component 12 also remains in its relative position about bent axle 4, thus, in the time should not changing the velocity ratio of speed changer 1 without continuous energising.In addition, generally speaking obtain the very high resultant gear ratio between the adjusting displacement between worm screw 40 and bent axle 4 and eccentric component 12, thus, motor can directly drive worm screw 40 without additional intermediate gearing in the situation that.In addition, bent axle 4 can be constructed to obtain relative rigidity, even if because this bent axle generally speaking also can have relatively large cross section in the region of guiding area 18.
