Abstract
The utility model discloses a monodirectional two-way gear drive device, which belongs to the technical field of the gear drive. The utility model comprises a rack bar which swings or is controlled in a push-pull way, two monodirectional excess clutch devices, an idler used for speed changing and reversing, and a driven gear. So, a dynamic force rotating shaft which is connected with the driven gear can be caused to rotate continuously and uniformly in a unidirectional way. The utility model overcomes the shortcoming of the intermittent rotation of the dynamic force rotating shaft of the monodirectional gear drive device existed in the prior art and can be widely used for gear drive devices which work by swinging or pushing and pulling.
Description
The utility model belongs to the gear transmission technology field.Specifically, relate to the unidirectional drive mechanism of a kind of reciprocating type round trip gear.
At present, by waving or push-pull effort acting drives the structure that other device rotates by gear transmission, just utilized wave or the push-and-pull process in the acting of one way realize the transmission of merit, and another one way only is the mechanical return that is used for finishing and idle output.Thereby the rotation that makes driven device exists the shortcoming of intermittence.
The purpose of this utility model is waved or the round trip of push-and-pull does work the device of other device uniform rotation of actuation gear transmission with regard to providing a kind of can the utilization.
The purpose of this utility model is achieved in that
Reciprocal nonreversible gear drive: the tactic gear in front and back fixedly side arm, middle frame, after-frame is interfixed by strut, the driven gear and the idle pulley that have power shaft are meshed, and the overcoat gear of two mono-directional overrun clutchs is meshed with the small gear and the driven gear of idle pulley; The sector rack of a band handle is fixed between described middle frame and the after-frame by stationary axle, and is meshed with the star-wheel gear of two mono-directional overrun clutchs; The orphan of the breach of the star-wheel of described two mono-directional overrun clutchs is on the contrary.
Its additional technical feature is: on the sector rack of band handle a round shift hole is arranged; Two the mono-directional overrun clutch overcoat gears and the gearwheel of idle pulley, the number of teeth (n of small gear
Outside 1, n
Outside 2, n
Lazy big, n
Lazy little) should satisfy relation: n
Outside 1N
Lazy big=n
Outside 2N
Lazy little
This scheme can realize swing reciprocal nonreversible gear transmission.
Another each technological scheme of the present utility model is: a kind of reciprocal nonreversible gear drive is characterized in that: the tactic gear in front and back fixedly side arm, middle frame, after-frame is interfixed by strut, the driven gear and the idle pulley that have power shaft are meshed, two unidirectional more the overcoat gear of clutch be meshed with the small gear and the driven gear of idle pulley; The tooth bar that has a displacement aperture is fixed in and is meshed between the frame after-frame and with the star-wheel gear of two mono-directional overrun clutchs in described; The orphan of the breach of the star-wheel of described two mono-directional overrun clutchs is on the contrary.
This scheme can realize plug-type reciprocal nonreversible gear transmission, makes the device uniform rotation of being fixed in driven gear shaft.
The reciprocal nonreversible gear drive that the utility model proposed is compared with prior art has following advantage: it can be waving or push-and-pull institute work converts the unidirectional uniform rotation of same driven spindle that makes in the gear transmission to; This apparatus structure is simple; Of many uses.
The drawing explanation:
Fig. 1: gear transmission schematic diagram
Fig. 2: the transmission principle figure of sector rack
Fig. 3: the star-wheel breach figure of first, second mono-directional overrun clutch
Fig. 4: the spur rack transmission principle figure of second technological scheme
Following structure accompanying drawing is described in further detail structure of the present invention and working principle:
Be illustrated in figure 1 as the gear transmission schematic diagram of reciprocal nonreversible gear drive.The side arm 1, middle frame 2 and the after-frame 3 that are used for fixing gear are fixing by fixed support bar 4.The idle pulley 7 that the driven gear 8 of drive rotating shaft 9 has reached speed change commutation effect is fixed between side arm 1 and the middle frame 2, and the gearwheel 13 of idle pulley is meshed with driven gear 8; Two mono-directional overrun clutchs 5,6 are fixed between side arm 1 and the after-frame 3, and the overcoat gear 15 of first free wheel device and the small gear 14 of idle pulley are meshed, and the overcoat gear 18 of second free wheel device is meshed with driven gear 8; A sector rack 10 that has handle 23 and displacement aperture 12, (as shown in Figure 2) be fixed between middle frame 2 and the after-frame 3 by stationary axle 11, displacement aperture is through in the positioning shaft 24, and the gear 17,20 of the star-wheel of sector rack 10 same two mono-directional overrun clutchs is meshed.Wave the handle 23 of sector rack during use, the gear that fan-shaped gear piece drives two star-wheels rotates.When sector rack handle 23 was moved to the left, 10 of sector racks drove two star-wheel gears 17,20 and rotate counterclockwise.Because the arc of the breach 21,22 of two star-wheels is to opposite (as shown in Figure 3), then the star-wheel 16 of first free wheel device dallies with respect to its overcoat gear 15 at this moment, the star-wheel 19 of second free wheel device then drives its overcoat gear 18 and rotates counterclockwise, and drives driven gear 8 and the rotation of power shaft 9 clockwise directions; When the handle 23 of sector rack moves right, then driving two star-wheel gears 17,20 and star-wheel 16,19 clockwise rotates, at this moment, the star-wheel 19 of second free wheel device is with respect to its overcoat gear 18 idle running, and star-wheel 16 its overcoat gears 15 of drive of first free wheel device clockwise rotate, after large and small gear 13, the 14 speed changes commutation of idle pulley 7, drive the driven gear 8 that is meshed with idle pulley and clockwise rotate.Desire to make driven spindle 9 to rotate in the counterclockwise direction, only needing that then the star-wheel 16,19 of two mono-directional overrun clutchs is switched a upper/lower positions can realize.Can both do work when waving driven spindle is rotated along same direction thereby reached when sector rack is left and right.
In order to make the rotating speed of driven spindle when sector rack is vacillated now to the left, now to the right even, then according to the gear principle of rotation, the star-wheel gear of its first and second mono-directional overrun clutch, the number of teeth n of overcoat gear
1 star, n
2 stars, n
Outside 1, n
Outside 2, with the number of teeth n of the big small gear of idle pulley
Lazy big, n
Lazy little, should satisfy following relationship:
n
Outside 1N
Lazy big=n
Outside 2N
Lazy little
Wherein generally get n
1 star=n
2 starsThe i.e. gear equal and opposite in direction of two star-wheels.
In addition: the sector rack in first scheme is changed into as shown in Figure 4, have the spur rack of rectangular displacement aperture 25, on spur rack, adorn the drive unit that a handle 26 can become plug-type reciprocal nonreversible gear again.
