Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the screw mechanism of anti-locking of the present utility model and wind-driven generator revolution part locking device are further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of screw mechanism of anti-locking, comprise: fixed component 1, swivel nut 2 and lock pin 3, fixed component 1 is provided with the space 4 of hollow, the through fixed component 1 of space 4, swivel nut 2 is arranged on one end of the space 4 of fixed component 1, and can rotate relative to fixed component 1, the screw rod 6 that lock pin 3 comprises the first end face 5 and is installed on the first end face 5, the axes normal of screw rod 6 is in the first end face 5, swivel nut 2 comprises perpendicular to screw axis, and second end face 7 relative with the first end face 5, screw rod 6 is threaded in the screw of swivel nut 2, and under the effect of swivel nut 2 rotary motion, be with pendulum lock pin 3 reciprocating in space 4, between first end face 5 and the second end face 7, damping device is set.
Screw rod 6 precession or back-out in swivel nut 2 is made by rotating swivel nut 2, band pendulum lock pin 3 is moved, thus make the first end face 5 near or away from the second end face 7, and, between first end face 5 and the second end face 7, damping device is set, can the first end face 5 near the second end face 7 time cushion the close speed of the first end face 5 to the second end face 7.The first end face 5 and the second end face 7 can be avoided like this to occur, and rigid contact causes swivel nut 2 and the locked phenomenon of screw rod 6 to occur.
As a kind of embodiment, damping device comprises buffer unit 8 and the first elastic member 9, and on the movable inwall being connected to space 4 of buffer unit 8, the first elastic member 9 is arranged between buffer unit 8 and the second end face 7.
When screw rod 6 is in swivel nut 2 during precession, first end face 5 moves when touching buffer unit 8 to the second end face 7, promote buffer unit 8 to move to the second end face 7 under the buffer function of the first elastic member 9, wherein the first elastic member 9 can be butterfly spring, butterfly spring rigidity is large, buffering vibration absorption ability is good, axial installation dimension is little, and larger load can be born in less space, in addition, butterfly spring combinationally uses conveniently, in real work, can adopt the mode of multi-disc butterfly spring serial or parallel connection.First elastic member 9 is not limited in butterfly spring, also can be the Compress Spring such as rubber spring or helical spring.
Particularly, buffer unit 8 is ring packing ring, and is sleeved on screw rod 6, the inwall of space 4 is arranged positive stop lug boss 10, for limiting the position of buffer unit 8.
When screw rod 6 is in swivel nut 2 during precession, the first end face 5 moves when touching buffer unit 8 to the second end face 7, promotes buffer unit 8 and moves to the second end face 7 under the buffer function of the first elastic member 9; When screw rod 6 screws out in swivel nut 2, the first end face 5 moves to the direction away from the second end face 7, and at this moment the first end face 5 can be separated with buffer unit 8, and now buffer unit 8 presses down in the elastic force effect of the first elastic member 9 and is attached on positive stop lug boss 10.
As a kind of embodiment, also comprise end cap 11, swivel nut 2 comprises edge 12, and end cap 11 is detachably connected on fixed component 1, and is limited in space 4 at the edge 12 of swivel nut 2.
Be limited in space 4 by end cap 11 by the edge 12 of swivel nut 2, can the edge 12 of just swivel nut 2 be limited in space 4, such swivel nut 2 can not spin off in space 4.Wherein end cap 11 can be fixedly connected on fixed component 1 by screw, can be convenient to dismounting end cap 11 like this thus make the dismounting of swivel nut 2 or installation become more simple and convenient.
More preferably, also comprise the second elastic member (scheming not shown), the second elastic member is arranged between the edge 12 of end cap 11 and swivel nut 2.Due to lock pin 3 be subject to external impact effect time, can impact force be delivered on swivel nut 2, make to produce impact force between the edge 12 of swivel nut 2 and end cap 11, by adopting, the second elastic member is set between end cap 11 and the edge 12 of swivel nut 2, impact force between the edge 12 that can cushion end cap 11 and swivel nut 2, thus avoid because of occur between end cap 11 and the edge 12 of swivel nut 2 impact cause swivel nut 2 and screw rod 6 locked.Second elastic member can be disk spring.
As a kind of embodiment, also comprise handwheel 13, handwheel 13 is fixedly connected with swivel nut 2, rotates for driving swivel nut 2.Particularly, between handwheel 13 with swivel nut 2, key is connected.Operator rotate swivel nut 2 by handwheel 13, the rotation of swivel nut 2 can be made to become lighter, and the mode adopting key to be connected between handwheel 13 with swivel nut 2 link together, and makes the dismounting of handwheel 13 or installation become more simple and convenient.
More preferably, also comprise gland 14, gland 14 is fixedly connected on swivel nut 2 by screw, and overlays on handwheel 13, can prevent handwheel 13 from going out gland 14 like this and come off from swivel nut 2.
In order to realize model utility object, as shown in Figures 2 and 3, the utility model also provides a kind of wind-driven generator revolution part locking device, comprise the screw mechanism of the solid of rotation 15 and above anti-locking of technical characteristics arbitrarily that lockhole 16 is set, lock pin 3 inserts or departs from the lockhole 16 of solid of rotation 15, for locking solid of rotation 15 or unlock under the driving of swivel nut 2.
Above embodiment makes the utility model have: reasonable in design, structure is simple, can avoid occurring rigid collision between lock pin and swivel nut, thus the advantage preventing screw thread locked.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
