Abstract

A mechanical driving device solves the problem that the present mechanical driving device only can do one-way operation, and two groups of gear driving mechanisms which do one-way operation are combined by sharing an input unit and an output shaft; wherein, when in work, the input direction and the output direction of one group are same, while that of the other group are opposite; the two groups of gear driving mechanism work asynchronously. The utility model can work in double directions, and the rotating direction does not need to be considered when the utility works and inputs, thereby being suitable to the occasions which have requirements for input rotating direction.

Description

A kind of mechanical transmission

Affiliated technical field

The utility model relates to a kind of mechanical transmission, especially imports sense of rotation and changes and the constant driving mechanism of output sense of rotation.

Background technique

Present mechanical transmission, all be to be formed by combining by series of gears, the output sense of rotation of this transmission device is relevant with power input sense of rotation, and be one-way only operation, be that power is during only with the input of certain sense of rotation, just have outputting power, transmission of power does not then take place in another direction.Like this, when transferring power, must be noted that the sense of rotation of power, this has the use of the occasion of requirement to bring certain inconvenience to some to the input power direction.

The model utility content

Can only this deficiency of one-way only operation for what overcome the existing machinery transmission device, the utility model provides a kind of new drive device, and this device can two-way working, and need not to consider to import the sense of rotation of power.

The technological scheme that its technical problem that solves the utility model adopts is: the gear drive of the two groups of one-way only operations mode with shared input body and output shaft is combined, wherein one group of when work input is identical with outbound course, another group work time input is opposite with outbound course, and two groups of driving mechanisms are not worked simultaneously.

The beneficial effects of the utility model are, but two-way working, and the sense of rotation when not needing to consider to import during work can be used in some have requirement to the input sense of rotation occasion effectively.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the utility model preferred embodiment.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 1.

1. input bodies among the figure, 2. ratchet, 3. transition gear, 4. output gear, 5. idle pulley, 6. ratchet, 7. spring, 8. transition gear, 9. intermediate gear, 10. ratchet, 11. ratchets, 12 springs, 14. output gears.

Embodiment

As shown in Figure 1, embodiment is made up of two groups of driving mechanisms, and their input body is identical with output shaft.That group on the left side (A-A to as shown in Figure 2) is made of two ratchets 11 of input body 1, ratchet 10, band spring 12, transition gear 8, three idle pulleys 5, output gears 4, ratchet 10 is connected as a single entity with input body 1, ratchet 11 is positioned on the transition gear 8, idle pulley 5 meshes and outer gearing respectively with in transition gear 8 and the output gear 4 between transition gear 8 and output gear 4.That group (B-B to as shown in Figure 3) on the right is made of two ratchets 6, transition gear 3, intermediate gear 9, the output gear 14 of input body 1, ratchet 2, band spring 7, ratchet 2 is connected as a single entity with input body 1, ratchet 6 is positioned on the transition gear 3, and intermediate gear 9 meshes respectively with in transition gear 8 and the output gear 14; Ratchet 10, ratchet 11 are opposite with the direction of ratchet 2, ratchet 6, and promptly the ratchet of two groups of driving mechanisms, ratchet direction are opposite, do not work simultaneously.

Output gear

4 and 14 rotating shaft are the same axises.The input body is given transition gear by ratchet and pawl with transmission of power, and reaching output gear by idle pulley or intermediate gear again is output shaft.

Shown in Fig. 2 (A-A to), when input body 1 clockwise rotates, transition gear 8 is also clockwise rotated by ratchet 10, ratchet 11, by idle pulley 5 output gear 4 is rotated counterclockwise again.And corresponding diagram 3 this moment (B-B to), the turning to along rotating counterclockwise of

input body

1,6 on ratchet 2 and ratchet are in the state of getting loose, and the transmission of power does not take place.

When input body 1 rotated counterclockwise among Fig. 2, ratchet 10 and ratchet 11 got loose, and this group driving mechanism is not worked; Corresponding diagram 3 this moment (B-B to), turning to along clockwise rotating of

input body

1,6 on ratchet 2 and ratchet are in and connect and state, transition gear 3 is also clockwise rotated, driving intermediate gear 9 by the internal tooth engagement clockwise rotates, drive output gear 14 by internal gear engagement again and clockwise rotate, corresponding A-A to gear 14 for rotating counterclockwise.As seen, no matter input body 1 is clockwise or rotates counterclockwise that the outbound course of embodiment device all is counterclockwise.

If the ratchet among Fig. 2, Fig. 3, ratchet direction are exchanged, no matter how import sense of rotation, the outbound course of embodiment device all is clockwise so.

As long as change the shape of input body 1, input mode can adopt the kinds of drive such as shaft drive, gear transmission, belt transmission.

Because input is transmitted respectively by two groups of gear drives with output, when the output gear 4 and the idle pulley 5 meshed gears numbers of teeth equal to import the gear 14 and the intermediate gear 9 meshed gears numbers of teeth, and transition gear 3 is when 8 the number of teeth also equates, no matter the embodiment device input is identical with outbound course or opposite, and its velocity ratio is identical.
