Abstract
The utility model provides a big space quill shaft rotational delay platform, include: base, cavity rotation axis, location bearing, worm wheel, worm and drive arrangement, seted up the storage tank on the base, the cavity rotation axis passes through location bearing rotation connection and is in with running through in the storage tank, cup jointed the worm wheel on the cavity rotation axis, the worm wheel has the worm through the meshing of gear mode, and the worm is connected with the drive arrangement drive to rotated by drive arrangement drive, drive arrangement sets up on the base, is provided with the drive arrangement mounting panel bottom it, the utility model provides a big space quill shaft rotational delay platform, simple structure, the design is reliable, possesses self -locking function to be favorable to the threading.
Description
Technical field
The utility model relates to deceleration stage field, particularly relates to a kind of large space quill shaft and rotates deceleration stage.
Background technique
Along with the social application of security product is more and more wider, performance requirement security protection being produced to deceleration stage is also more and more higher, security protection deceleration stage needs to utilize quill shaft to carry out threading at work, because existing security protection deceleration stage threading hole is very little, has a strong impact on the normal use of security protection deceleration stage; In addition, security protection deceleration stage lacks certain auto-lock function, and under free state, deceleration stage easily rotates, and the problems referred to above need solution badly.
Model utility content
Based on the technical problem that background technique exists, the utility model proposes a kind of large space quill shaft and rotate deceleration stage, to solve the problems of the technologies described above.
A kind of large space quill shaft that the utility model proposes rotates deceleration stage, comprising: pedestal, hollow rotating shaft, positioning bearing, worm gear, worm screw and drive unit; Pedestal penetratingly offers containing groove, hollow rotating shaft is rotatably connected in described containing groove by positioning bearing, hollow rotating shaft is socketed with worm gear, worm gear is engaged with worm screw by gear manner, worm screw drives with drive unit and is connected, and driving rotation by drive unit, drive unit is arranged on pedestal, is provided with drive unit mounting plate bottom it.
Preferably, hollow rotating shaft, positioning bearing and worm gear are coaxially arranged.
Preferably, drive unit is drive motor.
A kind of large space quill shaft that the utility model proposes rotates deceleration stage, drive unit output shaft drives worm screw to rotate, worm drive drives worm drive, worm gear set is connected on positioning bearing, its rotate and drive hollow rotating shaft to rotate, the large space quill shaft that the utility model proposes rotates deceleration stage, structure is simple, reliable design, the auto-lock function of hollow rotating shaft is achieved by worm gear and worm drive mode, and because the output external diameter of drive unit is much smaller than worm gear external diameter, described hollow rotating shaft size can design larger, thus be conducive to the threading of the threading hole of centre rotational axis.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of large space quill shaft that the utility model proposes rotates deceleration stage.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation that a kind of large space quill shaft that the utility model proposes rotates deceleration stage.
With reference to Fig. 1, the one that the utility model proposes comprises: pedestal 1, hollow rotating shaft 2, positioning bearing 3, worm gear 4, worm screw 5 and drive unit 6; Pedestal 1 penetratingly offers containing groove, hollow rotating shaft 2 is rotatably connected in described containing groove by positioning bearing 3, hollow rotating shaft 2 is socketed with worm gear 4, worm gear 4 is engaged with worm screw 5 by gear manner, worm screw 5 drives with drive unit 6 and is connected, and driving rotation by drive unit 6, drive unit 6 is arranged on pedestal 1, is provided with drive unit mounting plate bottom it.
In the present embodiment, drive unit 6 output shaft drives worm screw 5 to rotate, and worm screw 5 transmission drives worm gear 4 transmission, and worm gear 4 is socketed on positioning bearing 3, and it is when rotating and drive the rotation of hollow rotating shaft 2.
In such scheme, hollow rotating shaft 2, positioning bearing 3 and worm gear 4 are coaxially arranged, and the motion of hollow rotating shaft 2 is more steady.
Drive unit 6 is drive motor, and be convenient to adjustment hollow rotating shaft 2 rotating speed, its power is abundant.
The large space quill shaft that the utility model proposes rotates deceleration stage, structure is simple, reliable design, the auto-lock function of hollow rotating shaft is achieved by worm gear and worm drive mode, and because the output external diameter of drive unit is much smaller than worm gear external diameter, described hollow rotating shaft size can design comparatively large, thus is conducive to the threading of the threading hole of centre rotational axis.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
