Embodiment
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of dbl act tool and stops the dynamic response rotary speed shifting mechanism, comprise motion input disk 1, be movably installed with gear slide 5 on described motion input disk 1, between described motion input disk 1 and gear slide 5, gear mechanism is installed; Offer chute 7 on described gear slide 5, be movably installed with slide block 3 in described chute 7; Described slide block 3 is hinged and connected with gear mechanism.Described gear mechanism comprises gearwheel 2,2 small gears 4, and described gearwheel 2,2 small gears 4 are hinged and connected with motion input disk 1 respectively; Offer 2 chutes 7 on described gear slide 5, the interior slide block 3 that is movably installed with respectively of described 2 chutes 7; Described small gear 4 is hinged and connected with slide block 3.Described gearwheel 2 overlaps with motion input disk 1 center of circle.
In the process of transmission, motion input disk 1 is the uniform speed rotation along circle central axis.Motion input disk 1 is when uniform motion, the gearwheel 2 that is arranged on motion input disk 1 maintains static, small gear 4 is the uniform speed rotation along the surperficial track of gearwheel 2, the rotating center of small gear 4 is along with motion input disk 1 uniform motion, synergy promotes the movement of slide block 3, thereby makes gear slide 5 be output as the speed-changing rotation motion of certain rule.
As shown in Figure 2, in figure, abscissa is the angle of rotation of input; Y coordinate is the angle of rotation of output.In a cycle of motion, the total angle that the angle of rotation Φ of input and the angle of rotation α of output turn over is 360 °, wherein the angle of rotation Φ of input does the uniform speed rotation, and output angle rotatablely moves accordingly by the input of the motion in Fig. 3 disk 1 angle and corresponding gear slide 5 output angle rules.
The gear rotary speed shifting mechanism is the combination of a kind of gear mechanism and slide block slide carriage mechanism, and the employing of gear has reduced driving force greatly, has improved transmission efficiency.In the present embodiment, small gear 4 adopts Symmetric Mass to arrange, can reduce to a great extent the inertial force that in rotary course, whole driving mechanism produces.
A kind of dbl act tool that the present embodiment adopts stops the dynamic response rotary speed shifting mechanism, its compact structure, stability is high, is easy to run up, can be converted to coaxial speed-changing rotation output movement with at the uniform velocity rotating input motion, and can realize stopping-move-stop-moving characteristic output at intermittence.
