Abstract
The invention discloses a worm transmission mechanism. The worm transmission mechanism comprises a transmission shaft and a worm. A transmission gear sleeves the transmission shaft. The external surface of the transmission gear is provided with gear slots. The external surface of the worm is equipped with threaded slots. The threaded slots are butt joint with the gear slots and engage with the gear slots. The worm is externally connected to a driving motor, and the rotation control over the worm is realized by the driving motor, so the transmission gear can move by means of the threaded slots and the gear slots and then the transmission shaft is controlled to rotate.
Description
Technical field
The present invention relates to a kind of transmission mechanism, particularly a kind of worm gearing.
Background technology
Worm-drive is a kind of transmission of two between centers transmission campaigns at spatial intersecting and power, and the angle between two axial lines can be arbitrary value, and conventional is 90 °.Worm-drive is used for transmitting motion and power between alternating axis.Existing worm gearing is poor stability in the process rotated.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provide a kind of worm screw external drive motors, rotation can be carried out to worm screw by drive motors to control, thus conveniently by thread groove and teeth groove, travelling gear be moved, control the worm gearing that power transmission shaft rotates.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of worm gearing, comprise power transmission shaft and worm screw, driving sleeve is equipped with travelling gear, and the outer surface of travelling gear is provided with teeth groove, and the outer surface of worm screw is set with thread groove, and thread groove docks with teeth groove, and thread groove docks by being engaged with teeth groove.
Further, lock nut is provided with between described power transmission shaft and travelling gear.
Further, the two ends of described worm screw are respectively equipped with the first lock ring and the second lock ring.
Adopt the worm gearing of technique scheme, the external drive motors of worm screw, rotation can be carried out to worm screw by drive motors and control, thus conveniently by thread groove and teeth groove, travelling gear be moved, control power transmission shaft and rotate.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical 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 worm gearing of the present invention;
Fig. 2 is the exploded view of worm gearing 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 worm gearing, comprises power transmission shaft 1 and worm screw 5, power transmission shaft 1 is set with travelling gear 2, and the outer surface of travelling gear 2 is provided with teeth groove 3, and the outer surface of worm screw 5 is set with thread groove 6, thread groove 6 docks with teeth groove 3, and thread groove 6 docks by being engaged with teeth groove 3; Be provided with lock nut 4 between power transmission shaft 1 and travelling gear 2, the two ends of worm screw 5 are respectively equipped with the first lock ring 7 and the second lock ring 8.
Worm gearing of the present invention, the external drive motors of worm screw 5, can be carried out rotation to worm screw 5 by drive motors and control, thus conveniently be moved by thread groove 6 and teeth groove 3 pairs of travelling gears 2, control power transmission shaft 1 and rotate.
Wherein, between power transmission shaft 1 and travelling gear 2, be provided with lock nut 4, so install more firm.
Wherein, the two ends of worm screw 5 are respectively equipped with the first lock ring 7 and the second lock ring 8, so install more firm.
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 range that protection scope of the present invention should limit with claims is as the criterion.
