Abstract
This invention relates to a large angle oscillation non-impulse starting intermittent mechanism, which belongs to the machine mechanism technology field. The third intermittent external gear and intermittent internal gear form duplicate gear, which axes is fixed on the third intermittent external gear fixing shaft. The third intermittent external gear is in gear with first intermittent external gear. Intermittent internal gear is in gear with second intermittent external gear. The first intermittent external gear and second intermittent external gear form duplicated gear. The side face of the second intermittent external gear is fixed with cam. The side face of intermittent internal gear is fixed with roller. The said intermittent internal gear is arranged with pinning arc. This invention fulfills positive and opposite constant speed driving. It does not change the direction of acting force. This invention also fulfills driving steadily.
Description
Technical field
The present invention relates to a kind of large angle pendulum motion and non-impacting start-up intermittent mechanism, belong to the mechanical mechanism technical field.
Background technique
Some carries out member in mechanized equipment wide-angle constant speed reciprocally swinging, realizes resting when two ends are long and the occasion of smooth starting requirement, normally adopts guide-bar mechanism, cam mechanism and guide rod cam combined mechanism.Although these mechanisms can realize the form of reciprocally swinging, have following problem: for cam mechanism: pivot angle can too big (generally not surpass 60 degree), reduces transmission force property or self-locking otherwise pressure angle is big.For guide-bar mechanism: can not realize the moving for a long time relation of stopping, its output movement is a speed change, can produce impact when starting and stopping.For guide rod cam combined mechanism: complex structure, connecting rod self can balance be suitable at a high speed.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of large angle pendulum motion and non-impacting start-up intermittent mechanism is provided, can realize the transmission of positive and negative both direction constant speed, do not change the direction of active force, realize stable drive; Can be implemented in start and stop instantaneous and steadily excessively reach no impact effect.
Main solution of the present invention is achieved in that
The present invention mainly adopts the first incomplete external gear and the second incomplete external gear to form duplicate gear, and its axle center is all stationary axle, and what be meshed therewith has the 3rd incomplete external gear, the 3rd an incomplete external gear and incomplete internal gear composition duplicate gear; Its axle center is all stationary axle, the first incomplete external gear and the 3rd incomplete external gear engagement, the not exclusively internal gear and the second incomplete external gear engagement, at the second incomplete external gear side fixed installation cam, at incomplete internal gear side fixed installation roller, and not exclusively on the internal gear pinning arc is being set.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Utilize a pair of incomplete external gear pump and a pair of incomplete inside engaged gear to realize the transmission of positive and negative two direction constant speed, do not change the direction of active force, realize stable drive; Utilize a pair of pinning arc to realize stopping for a long time of two directions; That utilizes pair of cams to be implemented in to start and stop instantaneously steadily excessively reaches no impact effect.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention is mainly by the 3rd incomplete external gear 1, not exclusively the areal 10, pinning arc 11 etc. of tooth distribution district 9, gear 1 gear teeth of external gear stationary axle 2, first incomplete external gear 3, first incomplete external gear stationary axle 4, the second incomplete external gear 5, incomplete internal gear 6, cam 7, roller 8, gear 3,5,6 are formed.
The present invention mainly adopts the 3rd incomplete external gear 1 and incomplete internal gear 6 to form duplicate gears, and its axle center is fixed on the 3rd incomplete external gear stationary axle 2.The first incomplete external gear 3 and the second incomplete external gear 5 are formed duplicate gear; Its axle center is fixed on the second incomplete external gear stationary axle 4.The 3rd incomplete external gear 1 and first incomplete external gear 3 engagements, not exclusively the internal gear 6 and second incomplete external gear 5 engagements fixedly mount cam 7 in the 3rd incomplete external gear 5 sides, be fixedly connected in incomplete internal gear 6 sides roller 8 is installed.
The present invention realizes the constant speed transmission of positive and negative two directions by a pair of the 3rd incomplete external gear 1 and first incomplete external gear 3 engagements and a pair of incomplete internal gear 6 and second incomplete external gear 5 engagements.Pin arc 11 and be located at and partly form concavo-convex corresponding circular arc with the light beam of the 3rd incomplete external gear 5 on the incomplete internal gear 6 and play the pinning effect, reach and make the long hold function of driven member.Cam 7 (corresponding on two sides) is fixed on the 3rd incomplete external gear 5, roller 8 is fixed on (corresponding on two sides) on the incomplete internal gear 6, two form cam mechanism, and the realization entire mechanism is stopped instantaneous realization non-impacting start and stopped the moving of motion.
Working principle of the present invention:
It is that initiatively the crop rotation constant speed is rotated that the first incomplete external gear 3 and the second incomplete external gear 5 are formed one, and it is follower that the 3rd incomplete external gear 1 is formed one with incomplete internal gear 6.During the motion beginning, when the first incomplete external gear 3 and the second incomplete external gear 5 are made constant speed and are rotated, this moment second, partial gear 5 meshed with incomplete internal gear 6, and the first incomplete external gear 3 and the 3rd not engagement of incomplete external gear 1, at this moment follower and initiatively crop rotation rotation in the same way.The plurality of teeth (having moving condition to determine the number of teeth) because the second incomplete external gear 5 and incomplete internal gear 6 are only distributing on cylindrical body, when the first incomplete external gear 3 and the second incomplete external gear 5 continuation motions, when moving to required angle, the second incomplete external gear 5 and not exclusively internal gear 6 disengaging engagements, the light beam body of the second incomplete external gear 5 and the pinning arc 11 generation effects on incomplete internal gear 6 at this moment, the first incomplete external gear 3 and the second incomplete external gear 5 are rotated further the 3rd incomplete external gear 1 and then stop with incomplete internal gear 6.Driving wheel turns over several angle, makes the cam be fixed on the second incomplete external gear 5 contact the inefficacy of pinning arc with roller on being fixed on partial gear 6.At this moment a thruster of cam 7 is moved roller 8 one sides (i.e. the first incomplete external gear 1 and incomplete internal gear 6) and is made non-impacting start.When the incomplete external gear 1 of follower the 3rd and the incomplete motion of internal gear 6 reach required speed, backward rotation is made in the first incomplete external gear 3 and the 3rd incomplete external gear 1 engagement.When the angle that oppositely turns over when driven member equated with the angle that forward turns over, another pinned arc and begins effect, and follower has resetted and stops to the initial position.Driving wheel is rotated further, and makes the opposite side cam be fixed on the second incomplete external gear 5 contact the inefficacy of pinning arc with the roller of opposite side on being fixed on partial gear 6.The opposite side of the roller 8 of the opposite side of cam 7 promotion at this moment (i.e. the 3rd incomplete external gear 1 and incomplete internal gear 6) is made non-impacting start, repeats the above-mentioned characteristics of motion.
