Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2, the transmission device of electric operating mechanism described in the utility model embodiment, comprise motor 1, shaft coupling 2, leading screw 3, screw 4, output shaft 5, institutional framework 6, connecting lever shift fork 7, leading screw 3 and the equipped rear integral installation of screw 4 are on institutional framework 6 is longitudinal, it is outside that motor 1 is arranged on institutional framework 6, be connected with leading screw 3 by shaft coupling 2, output shaft 5 and connecting lever shift fork 7 are arranged on institutional framework 6 transversely, meanwhile, the slide unit 9 at screw 4 two ends is placed in the chute 8 of connecting lever shift fork 7.Motor 1, shaft coupling 2, leading screw 3, screw 4, output shaft 5, institutional framework 6, connecting lever shift fork 7 entirety forms an interlocking system, leading screw 3 is driven to rotate by motor 1 rotating drive shaft coupling 2, leading screw 3 drives screw 4 to move linearly, thus drive connecting lever shift fork 7 to rotate, and then output shaft 5 is rotated, realize transmission output function.
Described slide unit 9 can be slide block or traveller, and when described slide unit 9 is traveller, traveller is directly fixed on screw, and can preferably hold in traveller outer cover spindle, and being rolled with chute 8 by bearing is coordinated; Or, also traveller can be fixed on screw by rotatable mode in the process implemented.
When described slide unit 9 is slide block, slide block is rotatable to be fixed on screw, in the process making screw drive connecting lever shift fork 7 to rotate, slides in the rotatable chute again 8 of slide block.
Mechanism driving speed is: separating brake (slowly)-centre (soon)-combined floodgate (slowly).Namely, when screw 4 drives connecting lever shift fork 7 to move to vertical with leading screw 3 time, the rotating speed of connecting lever shift fork 7 reaches the fastest, and when connecting lever shift fork 7 moves to two side positions, the rotating speed that the linear velocity of screw 4 rectilinear motion passes to connecting lever shift fork 7 then can decline, to form this transport characteristics that separating brake is slow, intermediate transmission fast, close a floodgate slow; It adopts simple structure, and improve reliability and the mechanical endurance of mechanism, the kind of drive simultaneously taked and switching characteristic require to be formed and coordinate preferably, reaches overall useful life of improving mechanism itself and isolating switch, meets the requirement of frequent operation.
In the process implemented, described shaft coupling 2 can adopt universal joint to substitute, the output shaft direction of motor and the transmission direction disalignment of leading screw can be made after adopting universal joint, the output shaft of motor and leading screw are that certain inclination angle is arranged, can transmission direction be converted like this, be convenient to design whole transmission device.Simultaneously, adopt universal joint to carry out alternative shaft coupling 2, the rotational angle of described leading screw can also be made to control, when leading screw has different inclination angles, the translational speed of the screw on leading screw will make connecting lever shift fork have different rotating speeds, and then realizes adjustable to the rotating speed of connecting lever shift fork.
