Embodiment
In order to which the technological means, technical characteristic, purpose of utility model and the technique effect that realize the utility model are easy to bright
It is white to understand, with reference to being specifically illustrating, the utility model is expanded on further.
As shown in Figure 1 to Figure 3, it is a kind of cross gear of the utility model, including a gear 1 and between waiting
Away from four gear arms 2 for being arranged in 1 periphery of gear, the structure of four gear arms 2 is identical, four gear arms 2
It is an integral molding structure with the gear 1.
The middle part of gear 1 in the utility model offers the axis hole 11 of an installation rotation axis 8；In the gear
1 wherein one side is equipped with the multiple sector structures 3 of height separately；The another side of the gear 1 is equipped with a boss
4。
A toothrow 5 is arranged with along the center line both sides of each gear arm 2；The top of each gear arm 2 is equal
It is gear paddy position 7 between adjacent two gear arm 2 for gear peak position 6.The gear peak position 6 and the gear paddy position 7 is and institute
State the concentric cambered surface of axis hole 11.
The sector structure 3 in the present embodiment is eight groups, the sector structure 3 include inclined-plane 31 and with the inclined-plane
31 vertical planes 32 to connect.Every group of sector structure 3 is with the center of gear 1 into 45 degree of angle.
Inclined-plane 31 in every group of sector structure 3 and the bottom surface 33 of gear in the present embodiment surround gear 1
Center height is distributed, and the bottom surface 33 is contour plane, and the chamfered edge side low with bottom surface 33 on the inclined-plane 31 overlaps.
With reference to figure 3, the boss 4 in the present embodiment is round boss, and eight semi-round balls are offered in the boss face
Shape limiting groove 41.
The gear 1 of the utility model is fixed in rotation axis 8, can only be rotated.Gear peak position 6 is fillet peak position,
Purpose is that driven pinion mate can preferably be held up in this position, and anodontia fillet is to more smoothly pass over.
With reference to figure 6 and Fig. 7, gear paddy position 7 is also the circular arc type that evagination arches upward, in order to prevents driven gear 9 from blocking
In Liang Gufeng lowest points, the arc of outer lug, just preferably can hold up dynamic engagement driven gear 9, therefore, specially cross
The peak-to-peak paddy position of gear two is designed as male type and the circular arc with this cross body for concentric circles.
9 diameter of driven gear in the present embodiment is subject to the restriction of gear peak position 6 and gear paddy position 7.If driven gear 9
Diameter it is excessive, then it can not rotary motion to the lowest trough position center of cross gear, it could even be possible to being stuck in cross
It cannot be rotated between two peak positions 6 of type gear, therefore the size of driven gear 9 is by the gear between adjacent gear arm gear peak position 6
The width of paddy position 7 determines.
Under the effect of external force, i.e., the vertical plane that one group of nail 12 is placed in sector structure 3 contacts the utility model, and external force is dialled
During the dynamic group of rotation of nail 12 so that sector structure 3 starts to rotate, and rotating direction is consistent with the force direction for dialling nail 12.
Since the vertical plane of sector structure 3 is with dialling nail 12 against contacting, 12 platforms for stirring 3 end face of sector structure are followed closely when dialling
When rank rotates forward, since the sector structure and gear 1 are connected as a single entity in itself, so gear 1 also rotates with.
It is pitch wheel between driven gear 9 and gear arm 2, cross gear is rotated around the rotation axis 8 of itself, so that band
Dynamic driven gear 9 rotates together.
With reference to figure 4 and Fig. 5, the utility model in specific implementation, at the opposite place of boss 4 during installation, equipped with it is spacing
The banking pin 13 that groove 41 is mutually clamped, is equipped with banking pin resetting spring 14 on the banking pin 13.
Driven gear 9 in the present embodiment while rotating, it also occur that the change of position.Nail is dialled when external force promotes
12 when rotating forward, when banking pin 13, which is rotated to, to be aligned with the limiting groove 41 on 1 back side boss 4 of gear, banking pin
13 enter in the limiting groove 41, realize spacing function.
Cross gear is forced to stop at this time, because on boss 4, eight have been beaten around the circular central of gear 1
Location hole, the angle between each positioning limit hole are just 45 degree, so in rotation, can play and turn to expected angle
Degree, realizes the function of positioning gear 1.Therefore after cross gear rotates 45 degree, reaching limiting groove 41 will necessarily be temporary
When stop.
With reference to figure 6 and Fig. 7, if the utility model middle gear body 1 is before rotation is started, the position of driven gear 9 is ten
The lowest trough position of font gear, and cross gear 1 rotation suspend after, at this moment the position of driven gear 9 also and then revolve
Stop on the position for the peak peak position for turning to have moved to cross gear.Cross gear is to surround the rotation axis 8 of itself
Rotation, therefore its movement locus is still circular.After 45 degree of rotation, only paddy position and the position of peak position are handed over for it
For change.Paddy position originally becomes peak position, and original peak position becomes paddy position.
Since the shape of the utility model is cross, but due to when driven gear 9 rotates all the time with gear arm
Intermeshing together, therefore due to such appearance structure, changes the track for engaging 9 rotary motion of driven gear, no longer
It is circular or ellipse, but it is cross as cross gear external form.Therefore such movement locus, changes mesh
The use scope of front gear industry.The range in gear application is expanded.Since gear motion track changes, so as to be directed to
The solution of property and meet this kind of not rounded movement locus machine driving and whole machinery field in application.
It is only the utility model preferred embodiment in summary, is not used for limiting the scope of the utility model.
The equivalence changes and modification that i.e. all contents according to present utility model application the scope of the claims are made, such as the change driven gear free degree
Other periodic movement locus are made it have, should all belong to the technology category of the utility model.
