The Bidirectional driving principle of the present embodiment controllable bidirectional check controller:
Be positive Heptagon for polygonal on fixed base 1, with the state in 2a, 2b, 2c tri-rollers for representative, analyze the state description transmission principle of roller 2.
Fig. 6-1 is depicted as the original state of fixed base 1, roller 2 and turnable otic placode 4 mutual alignment relation, in Fig. 6-1, positive Heptagon on fixed base 1 has a limit to be the level of state, parallel with the center line 4X of turnable otic placode 4, and the center line 4X of turnable otic placode 4 overlaps with the center line 1X of fixed base 1; The axis of roller 2a overlaps with axially bored line 4a in φ D1 on turnable otic placode 4, and roller 2a and the length of side are tangential on mid point M1; The axis of roller 2b overlaps with axially bored line 4b in φ D1 on turnable otic placode 4, and roller 2b and the length of side are tangential on mid point M2; The axis of roller 2c overlaps with axially bored line 4c in φ D1 on turnable otic placode 4, and roller 2c and the length of side are tangential on mid point M3; That is: each roller all meets above conditions dictate.
Proper engagement clearance delta 1 is provided with between roller 2 and output casing 3, the clearance delta 2=Δ 3>0 of roller 2 and endoporus φ D1, roller freely can rotate in endoporus φ D1, export casing 3 clockwise direction or counterclockwise all free to rotate, now establish turnable otic placode 4 to make turnable otic placode 4 keep free state with the Returnning spring of fixed base 1.That is: under turnable otic placode 4 keeps free state, export casing 3 clockwise direction or counterclockwise all free to rotate, both direction is all exportable.
The present embodiment controllable bidirectional check controller is check, the reverse principle exported in the same way:
Fig. 6-1 is depicted as the original state of fixed base 1, roller 2 and turnable otic placode 4 mutual alignment relation.If export casing 3 to rotate counterclockwise as rotating forward, other driving component is just being all mutually with body pivot direction.
Apply external force T0 to turnable otic placode 4 make it turn over angle θ 1 counterclockwise and remain on this state, to output casing 3 apply external force T3 make it have the trend rotated counterclockwise time, see Fig. 6-2, roller 2 rolls on the limit of turnable otic placode 4, produce displacement, making the limit of roller 2 and fixed base 1 and exporting gap between casing 3 is zero, even reaches faint interference, now the clearance delta 3> Δ 2>0 of roller 2 and endoporus φ D1; The trend that external force T3 makes it have to rotate counterclockwise is applied to exporting casing 3, owing to exporting the effect of frictional force F2 between casing 3 and roller 2, roller 2 is just made also to have the trend rotated counterclockwise, roller 2 produces small displacement, the clearance delta 2=0 of roller 2 and endoporus φ D1, and Δ 3 reaches maximum, now no matter much to output casing 3 externally applied forces T3, all can not make to export casing 3 to rotate counterclockwise (within structural strength allowed band), realize angle lock, i.e. check in the same way; If now apply external force-T3(negative sign to output casing 3 to represent that direction is contrary) make it have the trend rotated clockwise, owing to exporting the effect of frictional force F2 between casing 3 and roller 2, roller 2 is just made to rotate clockwise, roller 2 produces displacement, makes the clearance delta 2>0 of roller 2 and endoporus φ D1, Δ 3>0, see Fig. 6-3, roller 2 freely can rotate in endoporus φ D1, makes to export casing 3 and can freely rotate clockwise, namely oppositely export.

The turnable otic placode of part in controllable bidirectional check controller, see Fig. 4, its structure also can be optimized, adopt in this programme and each wall of column pin hole is coupled together, become a simple beam structure entirety, increase its intensity and life-span, also can adopt and make cantilever structure.Fixed base can adopt the structural type of hollow shaft and solid shaft, n-shaped, N=3, and 4,5,6,7,8,9 ..., according to braking moment and can meet that size is actual to be determined.
Controllable bidirectional non-return device also can adopt the structure of planetary speed reducer; In controllable bidirectional non-return device and controllable bidirectional check speed reducer controllable bidirectional check controller output casing on tooth also can be designed to involute helical, effectively reduce noise, increase carrying.
Controllable bidirectional non-return device, controllable bidirectional check speed reducer can slow down with traditional speed reducer series multistage, can realize two-way return-stopping function equally.
When prime mover adopts conical rotor machine, can retain the braking function that motor inherently has, so just reach double brake function, its braking reliability is that geometry doubly increases, to requiring the reliable industry field important in inhibiting of braking superelevation.
When prime mover adopts conical rotor machine, the axial motion of rotor has former and later two directions, after the conical rotor machine energising in the present embodiment, rotor moves generation displacement backward, also can adopt the proal Cone-shaped electric machine of rotor, now the structure of pushing pin changes, see Figure 10.
Check control mode in controllable bidirectional check controller, controllable bidirectional non-return device, controllable bidirectional check speed reducer is by fixed base, and turnable otic placode realizes return-stopping function, is also this control mode adopted in this programme.Also by fixing otic placode, return-stopping function is realized by controlling base rotation.
