Abstract
The invention discloses a gear-driven worm mechanism. The gear-driven worm mechanism comprises a threaded rod, a spiral outer thread is arranged on the outer surface of the threaded rod, a driving end is arranged at one end of the threaded rod, a gear is arranged at the driving end, an outer thread is arranged on the outer surface of the gear, and a limiting block is arranged at the other end of the threaded rod. The gear is in butt joint with the external driving motor conveniently, the driving motor can control the gear to rotate, the threaded rod can be controlled to rotate, and accordingly, a worm function can be achieved conveniently through the threaded rod.
Description
Technical field
The present invention relates to a kind of worm mechanism, particularly a kind of gear-driving worm mechanism.
Background technique
Worm screw refers to have one or several helical tooth, and engages with worm gear and form the gear of gear pair with non-parallel.Its reference surface can be cylndrical surface, conical surface or toroidal surface.Existing worm screw is inconvenient to drive, and especially inconvenience carries out rotary actuation by gear.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provide a kind of gear conveniently to dock with external drive motor, drive motor can realize rotating by control gear, thus threaded stem realization rotation can be controlled, the gear-driving worm mechanism of worm screw function is conveniently realized by threaded stem.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of gear-driving worm mechanism, comprise threaded stem, the outer surface of threaded stem is provided with outside thread, in the shape of a spiral, one end of threaded stem is provided with drive end to outside thread, and drive end is provided with gear, the outer surface of gear is provided with outside thread, and the other end of threaded stem is provided with limiting stopper.
Further, the described limiting stopper side of being shape.
Further, described limiting stopper and threaded stem are threaded connection.
The gear-driving worm mechanism of employing technique scheme, gear is convenient to be docked with external drive motor, and drive motor can realize rotating by control gear, thus can control threaded stem realization rotation, conveniently realizes worm screw function by threaded stem.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of gear-driving worm mechanism of the present invention;
Fig. 2 is the exploded view of gear-driving worm mechanism of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Figures 1 and 2, a kind of gear-driving worm mechanism, comprise threaded stem 1, the outer surface of threaded stem 1 is provided with outside thread, in the shape of a spiral, one end of threaded stem 1 is provided with drive end 2 to outside thread, and drive end 2 is provided with gear 3, the outer surface of gear 3 is provided with outside thread, and the other end of threaded stem 1 is provided with limiting stopper 4; Limiting stopper 4 side of being shape, limiting stopper 4 and threaded stem 1 are threaded connection.
Gear-driving worm mechanism of the present invention, gear 3 is convenient to be docked with external drive motor, and drive motor can realize rotating by control gear 3, thus can control threaded stem 1 realization rotation, conveniently realizes worm screw function by threaded stem 1.
Wherein, limiting stopper 4 and threaded stem 1 are threaded connection, so docking is convenient, easy to assembly.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
