Abstract
The utility model discloses a reduction mechanism with repeatedly moved output. The reduction mechanism comprises a driving gear and a driven gear meshed with the driving gear, wherein the driving gear and the driven gear are respectively provided with at least one half gear coaxial with the driving gear or the driven gear; a gear is arranged on a part of the gear edge of each half gear, wherein the part with the gear is not over 1/2 the perimeter of the half gear; the diameter of each half gear is less than that of the driving gear and the driven gear; a target gear is arranged between the two half gears, is alternately meshed with the gear parts of the two half gears and is fixedly arranged on an output shaft; and a gear rack transmission pair is arranged on the end part of the output shaft. Through the reduction mechanism with the repeatedly moved output, the target gear can be repeatedly moved by only four gears. The reduction mechanism is of a simple and compact structure, is stable in operation and not high in manufacturing requirement, and can be widely applied to products, such as fans, toys, handicrafts and the like.
Description
Technical field
The utility model relates to reducing gear, is specifically related to the reducing gear that a kind of output moves back and forth.
Background technique
Gear transmission is a type of belt drive the most common in the mechanical transmission fields, is used for the transmission of power and/or motion; About gear transmission, all very ripe in material selection, technology manufacturing, we can say, as long as can design gear pair, all be can be produced.On the other hand, in a lot of fields, the rotational motion that people need frequently be commutated like the action of shaking the head of electric fan, is to accomplish with the linear reciprocating motion of connecting rod, controls and the track of linear reciprocating motion is difficult, influences the kinematic accuracy of last parts; If can replace with reciprocal rotation, then more can guarantee precision, the stability of motion is also higher simultaneously.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of reducing gear that moves back and forth that has is provided.
For realizing above-mentioned purpose; The technological scheme of the utility model is the reducing gear that a kind of output of design moves back and forth; Said reducing gear comprises a driving gear and the driven gear that is engaged with, and it is characterized in that said driving gear respectively has at least one half coaxial with it gear with driven gear; Described half gear has the gear teeth in the part of its wheel rim, and the said part that has the gear teeth is no more than 1/2 of its girth; The diameter of said half gear is less than the diameter of driving gear and driven gear; Between two said half gears, also be provided with a target gear, the wheel toothed portion of said target gear and two and half gears is engagement alternately; Said target gear is fixedly installed on the output shaft, is provided with the gear rack transmission in the end of said output shaft.
Wherein, said driving gear is identical with the diameter of driven gear, and the diameter of two and half gears is also identical.
The shared radian of wheel toothed portion of said half gear is 100 °～180 °, and the phase place of said two and half gear tooths part is symmetry mutually.
On said target gear, be provided with rotatingshaft, on said rotatingshaft, be provided with the wagging pole of an adjustable angle, with the reciprocally swinging that carries out of target gear.
The utility model is when work, and the driven by motor driving gear rotates, and driving gear drives driven gear and rotates, and the sense of rotation of two gears is opposite; Because two and half gears are coaxial with driving gear and driven gear respectively, therefore two and half gears are also done rotation in the opposite direction; Through the appropriate design of double gear mounting point, make the phase places symmetry of two sections wheel toothed portions, guaranteed that like this two and half gears can be not simultaneously and the target gear engagement, close but successively drink with the target gear; When one and half gears and target gear ability to speak fashionable; Drive the target gear and rotate, free engagement after, the target gear continues to rotate by former direction because of effect of inertia; Another half gear and target gear engagement then; Drive the target gear and rotate round about, so circulation makes the target gear carry out reciprocal rotation.Because said target gear is fixedly installed on the output shaft, be provided with the gear rack transmission in the end of said output shaft, therefore above-mentioned move back and forth to be convertible into move back and forth.
The advantage and the beneficial effect of the utility model are: the reducing gear that this output moves back and forth; Can only just realize moving back and forth of target gear with four gears, simple and compact for structure, stable; It is not high to make requirement yet, can be widely used in the products such as electric fan, toy, artwork.
Description of drawings
Fig. 1 is the reducing gear schematic representation that the utility model output moves back and forth.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1, the utility model is the reducing gear that a kind of output moves back and forth, and comprises driving gear 1 and driven gear 2, and both intermesh, and driving gear drives driven gear and rotates; Driving gear has half gear 3 coaxial with it, and driven gear has the diameter of half gear 4, half gears 3,4 coaxial with it less than gear 1,2; At the wheel rim of half gear 3,4, respectively having 31,41, two sections shared radians of the gear teeth of one section gear teeth is 110 °, 180 ° of its phase phase differences; Between two and half gears, be provided with a target gear 5, target gear 5 is provided with rotatingshaft, and the wagging pole 61 of an adjustable angle can be housed.Or said target gear is fixedly installed on the output shaft, is provided with the gear rack transmission in the end of said output shaft, and therefore above-mentioned reciprocal rotation is convertible into and moves back and forth.
When driving gear 1 rotates, drive driven gear 2 and do rotation in the opposite direction, drive half gear 3 and 4 separately simultaneously and do rotation in the opposite direction; Because two sections gear teeth 31 and 180 ° of 41 phase differences mutually; When 31 during with target gear 5 engagement, half gear 4 separates with target gear 5, and this moment, target gear 5 drove rotation down at half gear 3; After the gear teeth 31 and target gear 5 are thrown off; Target gear 5 is rotated further several angle under effect of inertia, the gear teeth 41 of this later half gear 4 and 5 engagements of target gear drive the target gear and rotate round about; So circulation makes target gear 5 carry out reciprocal rotation.Because said target gear is fixedly installed on the output shaft, be provided with the gear rack transmission in the end of said output shaft, therefore above-mentioned move back and forth to be convertible into move back and forth.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
