Specific implementation mode
Proposed by the present invention to prevent surmounting intermittent drive mechanism, transmission power is inputted by input shaft 1, is transmitted through driving wheel 5
To follower 4, as shown in Figure 1, Figure 2, Figure 3 shows.To realize central gear 2 that anti-transcendent function is arranged, with input shaft 1, actively
Wheel 5 is co-axially mounted by splined shaft, is fixedly connected；If not considering the factors such as manufacturing process, input shaft 1, driving wheel 5, center
Gear 2 can be considered as the same part.
Gear stand 3 is centrally disposed, and there are one center mounting holes, are co-axially mounted with input shaft 1, can be around the axis of input shaft 1
Rotation；Wobble gear 9 sells the position of mounting hole for being installed on gear stand 3 by wobble gear 10；So that central gear 2 and pendulum
9 gear teeth of moving gear are meshed, as shown in Figure 4.
Follower 4 is provided with dynamic resistance boss 401, and dynamic resistance boss 401 is inserted into the through hole 301 set by gear stand 3, can
To be in contact with the power transmission boss 901 set by wobble gear 9, the aperture of through hole 301 is more than the diameter of dynamic resistance boss 401,
It is in order to ensure that power transmission boss 901 can successfully bypass dynamic resistance boss 401, as shown in Fig. 7, Fig. 8, Fig. 9.Follower 4 and resistance
Dynamic boss 401, which can manufacture, to be integrated, and the multiple parts being fixedly connected can also be manufactured into, depending on process conditions.
The embodiment of the present invention, by the two-way anti-conceptual design for surmounting intermittent drive mechanism, it is contemplated that rotary motion is moved
Mechanical characteristic, wobble gear 9 with right wobble gear 11, balance gear 13 be with right balance gear 14 be symmetrically arranged, and
Wobble gear 9 is with right wobble gear 11, balance gear 13 with right balance gear 14 according to the circumference that the axle center of input shaft 1 is the center of circle
Be uniformly distributed, implementation mechanism it is two-way it is anti-surmount with mechanism momentum balance, as shown in Figure 10, Figure 11.
Below in conjunction with the anti-operation principle for surmounting intermittent drive mechanism of the attached drawing detailed description present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, it when preventing surmounting intermittent drive mechanism work, is co-axially mounted, is fixedly connected with input shaft 1
Driving wheel 5, central gear 2 rotated together by direction shown in Fig. 2, Fig. 3 arrow with input shaft 1, driving wheel 5 presses shown in arrow side
When to rotation to Fig. 2, extreme position shown in Fig. 3, just start that follower 4 is driven to rotate together.
As shown in Figure 2 and Figure 3, since the passing power of driving wheel 5 and follower 4 is built between part there are larger gap,
If the not anti-measure surmounted, follower 4 can turn with the variation of resistance, inertia force and gravity in certain period of time
Speed is more than driving wheel 5, and here it is the overshoots that the present invention tries hard to prevent.
When driving wheel 5 is in extreme position shown in Fig. 3, and driving wheel 5 is rotated in an anti-clockwise direction with input shaft 1
When, the meshing state of central gear 2 and wobble gear 9 is as shown in figure 4, the follower 4 at this moment inverse time under the driving of driving wheel 5
Needle direction rotates.When the tool of follower 4 is there are one when the trend for surmounting driving wheel 5,401 meeting of dynamic resistance boss set by follower 4
Rotation occurs a micro-corner and dynamic resistance boss 401 is caused to touch the power transmission set by wobble gear 9 in the counterclockwise direction
Boss 901, as shown in Figure 5.
Power transmission boss 901, dynamic resistance boss 401, positive stop lug boss 201 prevent follower from surmounting the mechanics schematic diagram of driving wheel as schemed
Shown in 6.Observation chart 6, with wobble gear 9 by research object it is found that the diameter that power transmission boss 901 is applied by dynamic resistance boss 401
To power F, since power transmission boss 901 is arranged on the outside of the outside circle of wobble gear 9, dynamic resistance boss (401) is to power transmission boss (901)
Force vector be located on the outside of the outside circle of wobble gear (9), so the effect of radial load F makes wobble gear 9 obtain one
A torque M=FH around the rotation of 10 axis both clockwise direction of wobble gear pin；Torque M makes power transmission boss 901 and central gear 2
Set positive stop lug boss 201 is in contact, and positive stop lug boss 201 is as shown in Figure 6 for the reaction force N of power transmission boss 901.By scheming
6 it is found that M=FH=-NL.Under equalising torque state, the movement of dynamic resistance boss 401 and follower 4 is prevented, therefore passive
The trend that wheel 4 surmounts driving wheel 5 is prevented from.
When driving wheel 5 is rotationally clockwise by rotating in an anti-clockwise direction commutation, as shown in Figure 7.Central gear 2 with
The engagement of wobble gear 9 makes the generation of wobble gear 9 be rotated in an anti-clockwise direction as shown in Fig. 7 arrows, power transmission boss 901
It is in contact with dynamic resistance boss 401, as shown in Figure 7.Wobble gear 9 is rotated further, due to due to passing through set by gear stand
Hole aperture be more than dynamic resistance boss diameter, gear stand can in primary deflector angular range free deflection, so power transmission boss
901 contact reaction force with dynamic resistance boss 401 will make the direction beat as shown by the arrows in figure 8 of gear stand 3, power transmission boss 901
Also by continue along dynamic resistance boss 401 contour surface slide, when turning to state as shown in Figure 9, power transmission boss 901 then around
Dynamic resistance boss contour surface is crossed, to achieve the purpose that driving wheel can smoothly commutate.
As shown in Figure 10, Figure 11, wobble gear 9 is with right wobble gear 11, balance gear 13 and right balance gear 14
It is symmetrically arranged, and wobble gear 9 and right wobble gear 11, balance gear 13 and right balance gear 14 are according to input shaft 1
Axle center is that the even circumferential in the center of circle is distributed, the two-way anti-momentum balance surmounted with mechanism driving of implementation mechanism.
In conclusion a kind of of the present invention prevents that two-way rotary motion can be transmitted by surmounting intermittent drive mechanism, not by external force
It influences, which normally can commutate and start to walk, and the rotating speed of the two-way prevention follower of energy surmounts the rotating speed of driving wheel, can keep
Normal stable working condition, realizes the purpose of the present invention.
