Description
Technical field
The utility model relates to a kind of single motor and drives double-stroke structure.
Background technique
Existing double-stroke structure, is by Dual-motors Driving, and Dual-motors Driving adopts two parallel reduction gears mechanisms, complete independently double-stroke motion separately.It needs two cover control mechanisms and position feedback mechanism to coordinate, and just can realize double-stroke mechanism controls, and double-stroke structural volume is larger, and processing cost is higher, and control circuit is relatively loaded down with trivial details.
Model utility content
The purpose of this utility model is to provide that a kind of cost is low, reliability is high, the single motor in joint space-efficient drives double-stroke structure and method.
The purpose of this utility model is to realize like this, a kind of single motor drives double-stroke structure, it is characterized in that: comprise motor, six gears and four bearings, the first gear is arranged in axle I, the second gear is arranged in axle II, the first gear engages with the second gear, and the first unilateral bearing and the 3rd unilateral bearing are housed respectively between the 3rd gear, the 5th gear and axle II, and the first unilateral bearing and the 3rd unilateral bearing are oppositely installed in axle II; The 4th gear is arranged in axle III, engages with the 3rd gear, and the 6th gear is arranged on axle VI, engages with the 5th gear; The second unilateral bearing is housed in axle III, and the second unilateral bearing outer ring is fixed, with the first unilateral bearing in the same way, the 4th unilateral bearing is housed in axle VI, the 4th unilateral bearing outer ring is fixed, with the second unilateral bearing in the same way.
Feature of the present utility model is:
1. adopt single motor to drive double-stroke structure, utilize unilateral bearing, make motor shaft in the time of clockwise and anticlockwise, drive different driven shaft one-way rotation, realize double-stroke motion.Prerequisite is that two-pass movement process is asynchronous.
2. relatively existing double-stroke structure, has saved a drive motor, a set of motor shaft speed reducer, a set of control mechanism and position feedback mechanism, cost.
3. relatively existing double-stroke mechanism, only needs a set of control mechanism, improves accuracy and the speed of main control software processing information.
4. unilateral bearing-gear type reducing gear, with respect to existing reduction gears mechanism, step of reduction reduces, and reliability improves, cost, and save space.
Accompanying drawing explanation
Below in conjunction with embodiment's accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the working principle explanatory drawing of Fig. 1.
In figure, 1, the first gear; 2, the second gear; 3, the 3rd gear; 4, the 4th gear; 5, the 5th gear; 6, the 6th gear; A, the first unilateral bearing; B, the second unilateral bearing; C, the 3rd unilateral bearing; D, the 4th unilateral bearing.
Embodiment
As shown in Figure 1, figure axis I is motor shaft, and axle II, axle III, axle VI are driven shaft, and driven shaft III, axle VI can only one-way rotation under the effect of unilateral bearing.
A kind of single motor drives double-stroke structure, it is characterized in that: comprise motor, six gears and four bearings, the first gear 1 is arranged in axle I, the second gear 2 is arranged in axle II, the first gear 1 engages with the second gear 2, between the 3rd gear 3, the 5th gear 5 and axle II, the first unilateral bearing a and the 3rd unilateral bearing c are housed respectively, the first unilateral bearing a and the 3rd unilateral bearing c oppositely install in axle II; The 4th gear 4 is arranged in axle III, engages with the 3rd gear 3, and the 6th gear 6 is arranged on axle VI, engages with the 5th gear 5.The second unilateral bearing b is housed in axle III, and the second unilateral bearing b outer ring is fixed, with the first unilateral bearing a in the same way, the 4th unilateral bearing d is housed in axle VI, the 4th unilateral bearing d outer ring is fixed, with unilateral bearing b in the same way.
Working principle is as shown in Figure 2: when motor shaft I forward, be left-handed while supposing motor forward, the first gear 1 drives the second gear 2 transmitting torques, the second gear 2 drives the dextrorotation of driven shaft II, now, the first unilateral bearing a is in engagement, and the 3rd unilateral bearing c idle running.The first unilateral bearing a engagement the 3rd gear 3 drives the 4th gear 4 transmitting torques, and the 4th gear 4 drives driven shaft III left-handed.
In the time that motor shaft I is reversed, the dextrorotation of motor shaft I, the first gear 1 drives the second gear 2 transmitting torques, the second gear 2 drives driven shaft II left-handed, now, the first unilateral bearing a idle running, and the 3rd unilateral bearing c is in engagement, the 3rd unilateral bearing c engagement the 5th gear 5 drives the 6th gear 6 transmitting torques, and the 6th gear 6 drives the dextrorotation of driven shaft VI.
Self-lock mechanism is because the second unilateral bearing b, the 4th unilateral bearing d outer ring are fixed, and driven shaft III and axle VI can only unidirectional movements.Driven shaft III sense of rotation under the effect of the second unilateral bearing b is left-handed, and driven shaft VI sense of rotation under the effect of the 4th unilateral bearing d is dextrorotation.
In the time of the dextrorotation of axle II, the first unilateral bearing a is in engagement, and the 3rd unilateral bearing c idle running, the 5th gear the 5, the 66 is in free state.Driven shaft VI sense of rotation under the effect of the 4th unilateral bearing d is dextrorotation.Thereby prevent that the 5th gear 5 from engaging drive driven shaft VI and reversing with the 6th gear 6.In like manner, in the time that axle II is left-handed, the first unilateral bearing a idle running, and the 3rd unilateral bearing c is in engagement.Driven shaft III sense of rotation under the effect of the second unilateral bearing b is left-handed, thereby prevents that the 3rd gear 3 from engaging drive driven shaft III and reversing with the 4th gear 4.
