The specific embodiment
Below in conjunction with the specific embodiment, the present invention will be described in detail.
Referring to Fig. 1, a kind of sine curve plotter, comprises the speed adjusting gear and the sine mechanism that by connecting rod 21, connect.
Referring to Fig. 2, described speed adjusting gear comprises casing 1, sets gradually from top to bottom that the first rotating shaft 2, the second rotating shaft 3 and the 3rd rotating shaft 4, the first rotating shafts 2, the second rotating shaft 3 and the 3rd rotating shaft 4 are parallel to each other and in the same plane in casing 1; The first rotating shaft 2 two ends are fixed on casing 1 inwall, one end of the second rotating shaft 3 is fixed on casing 1 inwall, the other end stretches out casing 1 and is connected with outside wind 22, on casing 1, be provided with vertical chute 5, one end of the 3rd rotating shaft 4 is movably arranged in vertical chute 5, and the other end is flexibly connected with casing 1 by support 6; In the first rotating shaft 2, be arranged at intervals with the first gear 7 and the 3rd gear 8, in the second rotating shaft 3, be arranged at intervals with the second gear 9 and the 4th gear 10, the 3rd gear 8 and the 4th gear 10 are meshed, the bottom of the first gear 7 is provided with the tooth bar 11 with its engagement, and the other end of tooth bar 11 stretches out casing 1 and end is provided with fixture; In the 3rd rotating shaft 4, be movably set with the cone dish 12 and the left belt wheel 13 that are connected, cone dish 12 is connected by belt with the second gear 9, and left belt wheel 13 is connected with sine mechanism by belt.
The effect of speed adjusting gear is input power, speed change, transferring power and changes the sinusoidal frequencies omega of drawing.Because needs transmit power, what gear was done is to rotatablely move, and will have so axle to provide support for these gears.Due to the transmission of gear for fixed than transmission, so when the number of teeth of two gears that are meshed is different, the rotating speed that he transmits will change, and just need to have such a device to realize this function for the change sinusoidal frequencies omega of drawing.
Referring to Fig. 3, sine mechanism comprises perpendicular slide rail 14, sideslip rail 15 and two power bars 16, two power bars 16 and perpendicular slide rail 14 are in the same plane, between perpendicular slide rail 14 and two power bars 16, be provided with chalk folder 17, chalk presss from both sides 17 one end slips and is arranged on perpendicular slide rail 14, the other end is fixed on two power bar 16 one end, the other end of two power bars 16 and sideslip rail 15 are connected, on sideslip rail 15, be arranged with the expansion link 18 that can laterally slide along it, between expansion link 18 and perpendicular slide rail 14, be fixed with flexible pole socket 19, on flexible pole socket 19, be provided with rotating right belt wheel 20, right belt wheel 20 is connected with left belt wheel 13 by belt, connecting rod 21 one end are fixed on casing 1, and the other end is fixed on perpendicular slide rail 14.
Flexible pole socket 19 sidepieces have rectangular opening, and expansion link 18 stretches into rectangular opening and holds out against by bolt.
Operation principle of the present invention is: fixture is fixed on blackboard, when illustrator uses hand along counter clockwise direction turning handle 22, the 4th gear 10 is followed the second rotating shaft 3 and is rotated, then the 4th gear 10 drives the 3rd gear 8 to rotate along clockwise direction, and the 3rd gear 8 and the first gear 7 are all connected with the first rotating shaft 2, so the first rotating shaft 2 and the first gear 7 all clockwise rotate with the 3rd gear 8, final speed adjusting gear and sine mechanism are done level rectilinear motion to the right under the drive of the first gear 7.
When the second rotating shaft 3 rotates counterclockwise, under bel-drivenn effect, cone dish 12 rotates counterclockwise with the second rotating shaft 3, cone dish 12 is connected with left belt wheel 13, left belt wheel 13 also rotates counterclockwise, transmission bottom right belt wheel 20 at belt also rotates in the counterclockwise direction, under the drive of right belt wheel 20, expansion link 18 also rotates in the counterclockwise direction, slide in expansion link 18 tops on sideslip rail 15, force the 15 in the vertical direction motions of sideslip rail simultaneously, because two power bars 16 are connected with sideslip rail 15, therefore two power bars 16 also in the vertical direction move, thereby drive chalk folder 17 to slide on perpendicular slide rail 14, because sine mechanism and speed adjusting gear are connected by connecting rod and have level rectilinear motion to the right.After these two motions are synthetic, chalk folder is just a sine curve with respect to the track of blackboard.
If change the gearratio of belt between the 4th gear 10 and cone dish 12, with a push rod, from vertical chute 5, stretch into and firmly push up left belt wheel 13, thereby make left belt wheel 13 together with cone dish 12, push the other end of the 3rd rotating shaft 4 to, its distance can be adjusted according to actual conditions.
