Detailed description of the invention
The first embodiment: as shown in Fig. 1 Fig. 2, the micro-decolorization swinging table of making an uproar of this low consumption, comprises frame 1, pallet 2, motor 7 and transmission mechanism.Transmission mechanism in the middle of prior art mostly is the toggle of driven by motor, and the transmission mechanism that the present embodiment adopts has a hard ring 4 and three friction pulleys 5.Fig. 4 is visible for composition graphs 3: compared with friction pulley 5, and the diameter of hard ring 4 is very large.Fig. 6 is visible for composition graphs 5: friction pulley 5 is cylindrical, and compared with hard ring 4, the diameter of friction pulley 5 is very little.Three friction pulleys 5 by wheel shaft 10 direct or indirect be arranged in frame 1, the core wheel line of three friction pulleys 5 is triangular in shape, a friction pulley 5 is had at least to be driven by motor 7, three friction pulleys 5 contact with the medial surface of hard ring 4, hard ring 4 is hinged with fork 2 phase, and fork 2 is connected with pallet 3.Obviously, be fixedly connected with by the friction pulley 5 of driven by motor with wheel shaft 10, and with the active friction wheel of motor power output shaft rotation.Other friction pulley 5 and wheel shaft 10 are rotationally connected, and is can rotate around wheel shaft, is friction through hard ring and the driven pulley that rotates.
The position of three friction pulleys can have multiple, it is recommended that a kind of preferred mode in figure: have two friction pulleys 5 above, a friction pulley 5 below, two friction pulleys above connect with the power output shaft of two motors 7 respectively, be all driving wheel, and a friction pulley 5 is below driven pulleys.Obviously, these three friction pulleys 5 support a hard ring 4, and under the drive of motor 7, the inner side of active friction wheel 5 pairs of hard rings 4 produces friction, drives hard ring 4 to rotate, then drives whole transmission mechanism work.
The mechanical characteristic of Fig. 9 to transmission mechanism is analyzed, from mechanics general knowledge: frictional force equals normal pressure and coefficient of friction is long-pending, in the middle of this example, normal pressure t be the gravity f of hard ring at the contact point of friction pulley 5 and hard ring 4 madial wall to the component in friction pulley 5 core wheel direction.As can be seen here: under the condition that the coefficient of friction of friction material and the quality of hard ring 4 are determined, the angle α of the core wheel of two active friction wheels 5 and two lines in hard ring 4 center of circle is larger, hard ring gravity f along the component of friction pulley radial direction i.e. normal pressure t larger, frictional force also will be larger.Therefore, this example can preferred following parameter further: the angle α of the core wheel of two active friction wheels and the circle center line connecting of hard ring is greater than 120 ° above.Experiment proves: at 140 ° as well, its error should be limited within 2 ° this angle, is between 138 °-142 °.In like manner, make the angle of cut β of these two friction pulleys and hard ring two contact point tangent lines, because of relative with α angle, alpha+beta=180 °, being advisable with 40 ° in β angle, is limited in 38 °-42 °.
On the basis of above-mentioned transmission mechanism, hard ring 4 can carry out multiple design according to job requirement with the connected mode of fork 2.The structure that Fig. 1 Fig. 2 recommends is: fork 2 has swing arm 8 and tappet 9, the collar extension of hard ring 4 is fixed with connecting plate 6, and the center of connecting plate 6 is relative with the center of circle of hard ring 4.Fig. 8 is visible for composition graphs 7: connecting plate 6 is provided with eccentric shaft 11, and eccentric shaft 11 is hinged mutually with one end of swing arm 8, and the other end of swing arm 8 is hinged mutually with one end of tappet 9, and the other end of tappet 9 is connected with pallet 3, and pallet 3 is hinged with frame 1 phase.Other accessories, because belonging to prior art, repeat no more here.
From mechanics: the hard ring diameter of above-mentioned transmission mechanism can be more much bigger than the diameter of friction pulley, can obtain larger gearratio.In addition, owing to leaning on frictional drive power, not only low cost of manufacture, and transmission process impacts minimum, and almost do not have noise, the environment for laboratory does not have harmful effect.
The second embodiment: as shown in Figure 10, friction pulley is cylindrical, the diameter of cylinder two ends section is greater than the diameter at middle part, form one step, rub mutually with the inner side of hard ring in the middle part of cylinder, the step surface at two ends is clipped in hard ring both sides, thus obtains larger rubbing surface, and transmission performance significantly improves.
