Abstract
The utility model relates to a swinging angle regulation intensive device for a planetary gear train, which comprises a planetary frame, a planetary gear, a sun gear, a planetary shaft, a mandrel, a connecting rod, a hollow shaft and a cantilever pin shaft. The utility model is characterized in that a slot-shaped reinforcing sleeve is sheathed outside of a non-engagement part of a gear round surface of the sun gear and the planetary gear; both ends of a slot long axis arranged in the reinforcing sleeve are provided with circular arcs; a central distance of both of the ends of the circular arcs is equal to an engagement central distance of the planetary gear and the sun gear; both ends of circular arc faces are respectively movable fitted with an addendum circle surfaces which is corresponding to the planetary gear and the sun gear. Stepless regulation can be achieved by the utility model. The utility model has the advantages of stable engagement and small noise, and can be used as the swinging angle regulation intensive device of equipment, such as an electric fan, etc.
Description
The utility model relates to a kind of angle pendulum regulating mechanism of electric fan, especially a kind of swing angle regulation reinforcing device for epicyclic train of electric fan.
In the prior art, the planetary gear train oscillation angle adjuster of equipment such as electric fan is an eccentric assembling cantilever bearing pin on planet wheel, change crank length, the variable crank length structure of planetary gear train that its structure is made up of hollow shaft, mandrel, planetary pinion, the sun gear that is positioned at the mandrel bottom, cantilever bearing pin etc. by planetary pinion around the motion of sun gear.But this structure continuous stepless changes crank length, thereby regulate the oscillation angle of equipment such as electric fan by the connecting rod automatic stepless that is connected with the cantilever bearing pin, the user only needs a knob on the rotating panel to required pivot angle value, controlling mechanism just can automatically be transferred to corresponding pivot angle position to shaking the head of equipment such as electric fan, convenient and swift, follow one's bent.But since in sun gear and the planetary pinion engagement process sun gear to the external broach synergy of planetary axle center extrapolability and connecting rod, make the planetary pinion that is on the cantilever-shaped planet axis be subjected to a kind of centrifugal force to sun gear, thereby have influence on sun gear and planetary engagement stability, also produce the two abnormal dislocation, beat, wearing and tearing and noise, this is must be improved.
The utility model purpose is to provide a kind of swing angle regulation reinforcing device for epicyclic train stable, that noise is little that meshes for electric fan.
The utility model comprises planet carrier, planetary pinion, sun gear, planet axis, mandrel, hollow shaft, cantilever bearing pin and connecting rod, sun gear is positioned at the mandrel bottom, the non-mate of tooth top disc of planetary pinion and sun gear is with 1 strengthening sleeve outward, the endoporus of strengthening sleeve is microscler, the interior slotted hole major axis two ends of strengthening sleeve are circular arc, the centre distance of the interior slotted hole major axis two ends circular arc of strengthening sleeve equals the meshed center distance of planetary pinion and sun gear, and the arc surface at interior slotted hole major axis two ends is state movingly with planetary pinion and the corresponding tooth top disc of sun gear respectively.
With embodiment and accompanying drawing the utility model is described in further detail below:
Fig. 1 is the utility model embodiment's a overall construction drawing,
Fig. 2 is a strengthening sleeve schematic representation among the embodiment.
The utility model comprises planet carrier 9, planetary pinion 13, sun gear 14, planet axis 12, mandrel 17, hollow shaft 16, cantilevered axle 11 and connecting rod 10, sun gear 14 is positioned at mandrel 17 bottoms, the non-mate of tooth top disc of planetary pinion 13 and sun gear 14 is with 1 strengthening sleeve 15 outward, strengthening sleeve 15 endoporus are microscler, the major axis two ends of slotted hole are the circular arc of equal radii in the strengthening sleeve 15, the center of arc at slotted hole major axis two ends is apart from the meshed center distance that equals planetary pinion 13 and sun gear 14 in the strengthening sleeve 15, and the arc surface at interior slotted hole major axis two ends is state movingly with planetary pinion 13 and sun gear 14 corresponding tooth top discs respectively.The line of centres of the major axis of strengthening sleeve 15 and planetary pinion 13 and sun gear 14 coincides.Above embodiment sets up a complete closed loop indifference regulating system, and its working procedure is as follows: motor power is by worm screw 7, and worm gear 6, worm-wheel shaft 8 drive gearwheel 5 rotations.Put the spatial position of having decided breach 3 by the displacement that the adjusting knob (not shown) on the control panel is made in the certain limit baffle plate 4, promptly imported given signal to regulating system; Being conditioned object---crank length is taken a sample by cam swing mechanism, amplification by fork 2 and by the free end position feedback of fork 2 to baffle plate 4, baffle plate 4 itself is again a comparator, it obtains the difference of sampled value and setting value by computing, when sampled value is consistent with setting value, fork 2 positions overlap with breach 3 positions, and at this moment fork 2 whenever circles and all must do not stopped by breach 3; If sampled value is different with setting value, its free end was blocked by baffle plate 4 when fork 2 forwarded on baffle plate 4 positions, rushed open the clutch of support block 1 immediately and made mandrel 17 brakings, caused the planetary gear train action and change crank length, thereby changed the pivot angle of electric fan.Meanwhile, 2 swings of cam drive fork are slided fork 2 free ends on baffle plate 4 edges, constantly make comparisons on baffle plate 4 with new sampled value and setting value.Because cam profile is continuous, so no matter the change of setting value is to increase or reduce, sampled value finally can be consistent with setting value, at this moment fork 2 free ends find breach 3 and pass through breach 3, thereby discharge the mandrel 17 be braked and engaging clutch again, so fan is with new pivot angle operation.Since planetary pinion 13 and the sun gear 14 outer strengthening sleeves 15 that are with, this pivot angle operation be steadily, noise is little.
The utility model can be realized step-less adjustment, and its engagement is stable, noise is few, is that the desirable pivot angle of electric fan is regulated intensifier.
