Abstract
This invention is an intermittent gear direction changing mechanism. It includes parallel assembled input shaft, intermediate shaft and output shaft. Two intermittent tooth driving gear are fixed on the input shaft. One big all-dog intermediate gear and one small all-dog intermediate wheel are fixed on the intermediate shaft. One all-dog driven gear is fixed on the output shaft. The two intermittent driving gears are alternatively in gear with the big all-dog intermediate gear and all-dog driven gear. The small intermediate gear is in gear with the all-dog driven gear all the time. Thus, it fulfills two kinds of alternative direction changing driving mode. One intermittent tooth driving gear drives the all-dog driven gear directly. The other intermittent tooth driving gear drives the all-dog driven gear through the big and small all-dog intermediate gears. By adjusting the rotation rate of input shaft, the input shaft positive and negative rotation efficiency can be changed. This mechanism works steadily. It also has high control accuracy.
Description
Technical field
The present invention designs and a kind ofly turns under the prerequisite in the input shaft perseverance, and output shaft is done periodically break-in transmitting gear mechanism, belongs to mechanical engineering technical field.
Background technique
The research that has complex vibration in the working procedure such as aerospace equipment, military aircraft is more and more caused people's attention.From the documents and materials of grasping, most of research all is based on algorithm, sensory technique and curve reestablishing, and simulation itself that vibrate is not all caused people's attention all the time.Study shake shape diversification and may command in order to make, the driving source that can produce the controlled shape of shaking is essential.Driving source can be realized by the specific mechanism of driven by motor.There are crank rocker, cam, eccentric wheel, screw-nut body and gear mechanism etc. in this class mechanism.But these motions all have deficiency, and for example first three plants mechanism does not have strict velocity ratio, movement travel control difficulty, bumpy motion and cause thus that mechanism performance is poor, working life short.Particularly, can not ignore by the impact that velocity variations is brought in high speed situation.The two kinds of mechanisms in back can only realize that thereby clockwise and anticlockwise produces vibration by the direction that changes motor, and this obviously can not satisfy the demand under the high frequency situations.
Summary of the invention
The objective of the invention is to the defective that exists at prior art, a kind of Incompletion gear wheel direction changing transmission mechanism is provided, can reach permanent velocity ratio, output steadily and can satisfy the break-in transmission of high frequency occasion.
For achieving the above object, the technical solution adopted in the present invention is: a kind of Incompletion gear wheel direction changing transmission mechanism, comprise a kind of Incompletion gear wheel direction changing transmission mechanism, the input shaft, jack shaft and the output shaft that comprise parallel installation, it is characterized in that two incomplete tooth driving wheels of fixed installation on the described input shaft, a big full-depth tooth breast wheel of fixed installation and a little full-depth tooth breast wheel on the described jack shaft, full-depth tooth follower of fixed installation on the described output shaft; Described two incomplete tooth driving wheels alternately mesh and not engagement simultaneously with big full-depth tooth breast wheel and full-depth tooth follower, and described little full-depth tooth breast wheel meshes with the full-depth tooth follower all the time.Thereby realize two kinds of kinds of drive that replace of break-in moral: the direct transmission full-depth tooth of an incomplete tooth driving wheel follower; And another incomplete tooth driving wheel is through big full-depth tooth breast wheel and little full-depth tooth breast wheel transmission full-depth tooth follower.Little full-depth tooth breast wheel is connected with jack shaft by screw thread on the above-mentioned jack shaft, and fixes with self-locking nut at little full-depth tooth breast wheel two ends.Before nut is fixing, little full-depth tooth breast wheel is unrestricted around the rotary freedom of axis, so can it be arrived and output shaft full-depth tooth follower position engaged under the prerequisite that does not influence other gear engagement states by rotating the phase place of regulating little full-depth tooth breast wheel.
When input shaft clockwise rotates, mesh (at this moment, the big full-depth tooth breast wheel engagement on another incomplete tooth driving wheel discord jack shaft) as if full-depth tooth follower on an incomplete tooth driving wheel and the output shaft, then output shaft rotates counterclockwise.Full-depth tooth follower on the output shaft drives jack shaft by the little full-depth tooth breast wheel on the jack shaft and dallies clockwise.After the full-depth tooth follower was nibbled out on incomplete tooth driving wheel and the output shaft, the big full-depth tooth breast wheel on another incomplete tooth driving wheel and the jack shaft entered engagement.Because the input shaft direction is constant,, and drives output shaft by little full-depth tooth breast wheel and clockwise rotate so jack shaft rotates counterclockwise.Use this mechanism, only need input shaft to keep a direction to rotate, just can realize the periodic break-in campaign of output shaft.
Effect of the present invention is: between twice commutation, realize constant speed ratio and transmission stably.Mechanism's compactness of entire mechanism, simple, mechanical property is good.

Embodiment
Details are as follows in conjunction with the accompanying drawings for a preferred embodiment of the present invention: with reference to figure 1 and Fig. 6, this Incompletion gear wheel direction changing transmission mechanism includes input shaft (1), jack shaft (2) and the output shaft (9) of parallel installation, fixed installation two incomplete tooth driving wheels (2,3) on the described input shaft, described jack shaft (4) is gone up a fixed installation big full-depth tooth breast wheel (7) and a little full-depth tooth breast wheel (6), and described output shaft (9) is gone up a fixed installation full-depth tooth follower (8); Described two incomplete tooth driving wheels (2,3) alternately mesh and not engagement simultaneously with big full-depth tooth breast wheel (7) and full-depth tooth follower (8), and described little full-depth tooth breast wheel meshes with full-depth tooth follower (8) all the time.
Shown in Figure 2, little full-depth tooth breast wheel (6) is connected with jack shaft (4) by screw thread, fixes by self-locking nut (5).Before the adjusted position, two nuts (5) keep clear of little full-depth tooth breast wheel (6) earlier, and so little full-depth tooth breast wheel (6) just can rotate the phase place regulate the two around jack shaft (4), up to the engaging position of full-depth tooth follower (8).Because the phase adjusted of little full-depth tooth breast wheel (6) is all the time in the scope at a circular pitch angle, so the screw thread surplus of jack shaft (4) needn't be oversize, desirable 5～8mm.
Fig. 3 represents the structural drawing of incomplete tooth driving wheel (2).
Fig. 4 identifies the structural drawing of incomplete tooth driving wheel (3).
Fig. 5 represents that incomplete tooth driving wheel (2) and incomplete tooth driving wheel (3) are assemblied on the input shaft (1).As can be seen from the figure, a vacancy district (A) and a tooth overlap region (B) have been formed after the two incomplete gear assemblings.Overlap region (B) is to be continuity and the stationarity of guarantee transmitting, and the vacancy district guaranteed in the movement process not exclusively tooth driving wheel (2) and full-depth tooth follower (8), not exclusively tooth driving wheel (3) and greatly full-depth tooth breast wheel (7) can not mesh simultaneously and cause stuck.Can recently design the number of teeth of each several part according to different transmissions, the mechanism shown in Figure 6 vacancy district number of teeth is 8 teeth, and the overlap region number of teeth is 2 teeth.
