Description
Technical field
The utility model relates to a kind of mechanical driving device, particularly a kind of worm gearing.
Background technology
Worm gearing is widely used at mechanical field as a kind of commutation, speed change gear.But at present usually a used worm gearing can only once turn to, and rotation direction fixes, and applied occasion is limited.
In blind, make blinds carry out the mode that interlock is adopted, at present, mainly contain two kinds: a kind of is the crank interlock.In this interlock mode, an end of every blinds is equipped with crank connecting link spare entirely, and connector links to each other with drive link, and connecting rod drives all crank connector actions under external force, thereby reaches the effect of blinds interlock.The crank connector in design and to produce all be very complicated, and the blinds of different size is produced the crank connector of different size again, each other can not be general, can prolong the cycle of production undoubtedly again, another kind is the drag-line interlock, this interlock mode is that all ends are coupled together with two drag-lines, and power effect outside reaches the effect of interlock, and this undoubtedly mode is in the reliability of interlock and all be lower on the life-span.
The utility model content
The purpose of this utility model just is: the worm gearing that provides a kind of a plurality of output shaft to link simultaneously with identical direction or different directions.
For solving the problems of the technologies described above, technical scheme provided by the utility model is:
A kind of worm gearing that can multinomial interlock comprises the reducer group that several are made up of worm gear and worm screw, and described worm screw is hollow worm screw; Device also comprises the cover that is rotationally connected, splined shaft and several box bodys; Described splined shaft is a rotating shaft that is provided with spline; Described one group of hollow worm and worm wheel are fixed in the box body, and hollow worm set is on splined shaft, and the cover two ends that are rotationally connected are enclosed within respectively on hollow worm screw and the splined shaft.
The end of described hollow worm screw is the column gear; The described cover endoporus that is rotationally connected is divided into two sections, and one section roller gear with hollow worm screw matches, and another section matches with splined shaft.
Described box body side is provided with boss, and boss is provided with locating hole.
Described worm gear axle center is provided with through hole, is provided with spline in the through hole; Described device also comprises shaft coupling, and spline is established in the shaft coupling outside, and shaft coupling is connected with worm gear, the inboard spline axis hole that forms of this shaft coupling.
According to the technical scheme that the utility model provides, it has following advantage with respect to prior art:
This reducer adopted hollow worm screw and be in transmission connection the cover after, a plurality of reducer groups just can be serially connected on the power transmission shaft easily, when power transmission shaft rotates under the effect of external force, thereby all reducer turning cylinders will rotate the effect that reaches interlock with same orientation or different orientation with the same slow-speed of revolution on the direction of vertical worm gear.
Because not only reliable transmission of linkage structure that this reducer constituted, the life-span is long, in large and small blinds interlock all optional it as transmission device, design and cost of production thereby simplified blinds greatly.In addition, this reducer also can be made the universal speed reducer in the general curtain.

The specific embodiment
A kind of worm gearing that can multinomial interlock as shown in Figure 3, comprises the reducer group A that several worm gears and worm screw are formed.
Assembly drawing of the present utility model as shown in Figure 1, worm screw is hollow worm screw 2.In the present embodiment, the described device of present embodiment also comprises be rotationally connected cover 3, splined shaft 4 and several box bodys 5; Splined shaft 4 is the rotating shaft that evenly is provided with several splines on the circumference.The end of hollow worm screw 2 is a column gear 21.Cover 3 endoporus that are rotationally connected are divided into two sections, and as shown in Figure 2, one section roller gear shape with hollow worm screw matches, and another side and splined shaft shape match.The reducer group A that hollow worm screw 2 and worm gear 1 are formed is fixed in the box body 5, and hollow worm screw 2 is enclosed within on the splined shaft 4, and cover 3 two ends that are rotationally connected are enclosed within respectively on hollow worm screw 2 and the splined shaft 4.Box body 5 sides are provided with boss 51, and boss 51 is provided with locating hole 52.The worm gear axle center is provided with through hole 11, is provided with spline 12 in the through hole 11; The described device of present embodiment also comprises shaft coupling 6, establishes spline 61 on the shaft coupling 6, is connected these shaft coupling 6 inner spline axis holes 62 that form with worm gear 1 by the spline 12 in the through hole 11.
In actual applications, such as being used for blind,, be a kind of novel linkage by the linkage that it constitutes, make the more reliably more simple transmission device of blinds transmission.During use, fix a side lever 7 in the spline axis hole 62 on the shaft coupling 6, fixing blinds 8 on side lever 7 axial directions, as shown in Figure 3, the reducer group A that each worm gear and worm screw are formed adopts identical specification and gearratio, when rotating splined shaft 4, fixedly connected each reducer group A rotates with the phase same rate on the drive splined shaft 4, thereby drive each blinds 8, open simultaneously or close, the motion neat appearance.
Because not only reliable transmission of linkage structure that this reducer constituted, the life-span is long, in large and small blinds interlock all optional it as transmission device, design and cost of production thereby simplified blinds greatly.In addition, this reducer also can be made the universal speed reducer in the general curtain.
The utility model also can be according to the difference of application scenario, in the needs interlock but under the different situation of each output shaft rotating speed, such as clock and watch, and the reducer group A that each worm gear and worm screw are formed adopts different gearratios, as shown in Figure 4.
Because box body 5 sides are provided with boss 51, boss 51 is provided with locating hole 52, and the reducer group A with each worm gear and worm screw composition in the time of also can assembling adopts different start angles, by locating hole 52, is fixed on the support of side.So just form the form of output shaft different directions, thereby reached the purpose of multidirectional interlock output.As shown in Figure 5.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique is under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, such as, worm gear can adopt the inner form that directly forms the spline axis hole, and without shaft coupling, also can reach identical purpose, therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
