Abstract
The invention discloses a speed reducer for a micro motor which drives a camera monitor to move, comprising a reduction gear box and a three-level deceleration drive apparatus which comprises a worm 2, a first duplex gear 3, a second duplex gear 4 and a large gear 5. The worm 2 is arranged on the bottom of the reduction gear box and is driven by a micro motor 8. The first duplex gear 3 comprising a large worm gear 31 and a pinion 32 is arranged inside the reduction gear box and is slidingly sleeved on the gear mandrel 61. The large worm gear 31 is meshed with the worm 2. The second duplex gear 4 comprising a large gear 41 and a pinion 42 is arranged inside the reduction gear box and is slidingly sleeved on the gear mandrel 62, wherein, the large gear 41 is meshed with the pinion 32 of the first duplex gear 3. The large gear 5 is also arranged inside the reduction gear box and is meshed with the pinion 42 of the second duplex gear 4. The extended end of the large gear 5 is a spline output shaft. The speed reducer for a micro motor has the advantages of reducing the volume of the speed reducer, holding the gear inside the reduction gear box, and realizing vertical or horizontal rotating movement of the camera monitor.
Description
Technical field
The present invention relates to a kind of retarder.
Background technique
Along with the development of internet video, the network remote meeting is exchanged for daily life with shoot and monitor and has brought a lot of facilities with commercial affairs at present.And the retarder that micromachine wherein drives is individual very important components.The retarder of existing camera monitor as shown in Figure 6, it is big to exist volume, operative gear is exposed to the deficiency that thereby the outside of speed reducer is contaminated easily and damage, and the camera monitor that this part speed device drives can only be fixed a certain orientation and can not do up and down or horizontally rotate motion, influence further the dwindling and overall performance of volume of monitor unit, brought certain difficulty for the miniaturization of camera monitor.
Summary of the invention
The objective of the invention is, problem at above-mentioned prior art existence, the retarder that provides a kind of micromachine that is used for camera monitor to drive, the volume of this retarder can dwindle widely, its gear is included among the speed reducer, be not easy to damage and pollute, and can realize that the camera of monitor unit does up and down or horizontally rotate motion.
Realize that technological scheme of the present invention is: this retarder is the same with prior art, comprises speed reducer and three grades of reduction gearing mechanisms, and speed reducer comprises casing and case lid, and its improvement is that said three grades of reduction gearing mechanisms comprise:
One is contained in a worm screw 2 by micromachine 8 drivings of speed reducer bottom;
One is contained in first duplicate gear 3 in the speed reducer; This duplicate gear 3 comprises a big worm gear 31 and a small gear 32, wherein big worm gear 31 and worm screw 2 engagements; This duplicate gear 3 slides on the gear mandrel 61;
One is contained in second duplicate gear 4 in the speed reducer; This duplicate gear 4 comprises a gearwheel 41 and a small gear 42, wherein 32 engagements of the small gear in the gearwheel 41 and first duplicate gear 3; This duplicate gear 4 slides on the gear mandrel 62;
One is contained in the gearwheel 5 in the speed reducer; Small gear 42 engagements in this gearwheel 5 and second duplicate gear 4, its overhanging end is the spline output shaft.
The invention has the beneficial effects as follows:
1, it is reasonable to make that by present design this retarder has a simple structure, and overall volume is small and exquisite, easy for installation simple, is easy to realize further dwindling of camera monitor overall volume;
2, worm screw one worm gear that drives by micromachine and gear-box slows down and the driving of output shaft spline, make that camera monitor can be up and down or side-to-side movement, and it is reliable to have an overall co-ordination, shake little, noise is little, and bearing capacity is even, is difficult for hindering tooth, bump characteristics such as tooth, and then improved the class and the overall performance of camera monitor.
The present invention is more clear to be understood with being convenient in order to make, and below by drawings and Examples it is described further.

Embodiment
Present embodiment is shown in Fig. 1-5, and present embodiment comprises: comprise speed reducer and three grades of reduction gearing mechanisms, speed reducer comprises casing 1 and case lid 7.Three grades of reduction gearing mechanisms comprise: one is contained in a worm screw 2 by micromachine 8 drivings of speed reducer casing 1 bottom; One is contained in first duplicate gear 3 in the speed reducer; This duplicate gear 3 comprises a big worm gear 31 and a small gear 32, wherein big worm gear 31 and worm screw 2 engagements; This duplicate gear 3 slides on the gear mandrel 61; One is contained in second duplicate gear 4 in the speed reducer; This duplicate gear 4 comprises a gearwheel 41 and a small gear 42, wherein 32 engagements of the small gear in the gearwheel 41 and first duplicate gear 3; This duplicate gear 4 slides on the gear mandrel 62;
One is contained in the gearwheel 5 in the speed reducer; Small gear 42 engagements in this gearwheel 5 and second duplicate gear 4, its overhanging end is the spline output shaft.
In sum, this novel a kind of performance that described above only is, the present invention is not limited to the foregoing description form, and many variations can also be arranged, and only otherwise break away from design proposal of the present invention, can do all modal changes.Any equivalent modifications and modification that every foundation technological scheme of the present invention is done above example example all should be thought to belong to protection scope of the present invention.
