Abstract
The utility model discloses a worm gear structure of an elevating motor, comprising a worm gear meshed with a worm shaft of the elevating motor and a worm gear supporting base used for assembling the worm gear. The worm gear structure of the elevating motor is characterized in that the worm gear is equipped with a ring boss connected with the worm gear integrally, an externally mounted torsion spring is sleeved on the ring boss, and a fixing end of the externally mounted torsion spring is fixedly connected with a bracket of the elevating motor. The worm gear structure of the elevating motor employs a stable transmission structure of mounting the torsion spring externally, and is simple in assembling; by using the worm gear structure of the elevating motor, the displacement and swing generated when the worm gear works in the prior art are solved fundamentally, so that an accelerated wear situation is prevented from occurring due to the changes of the transmission cooperation clearance and angle, and at the same time, the structure is improved, and the production efficiency is improved substantially.
Description
Technical field
The utility model relates to a kind of power transmission that utilizes worm gear, worm speed-down, switching-over, specifically a kind of worm gear arrangement of lifting motor.
Background technology
Along with the raising day by day of scientific and technological progress people's lives, various intelligentized equipment and daily necessities can become main flow, and this moment, the intelligent equipment range of application was more and more wider; Intelligent elevated table, intelligent elevated stage; The intelligent elevated antenna of military field etc., the purposes of the worm gear arrangement of lifting motor is more and more wider, has substituted loaded down with trivial details systems such as original hydraulic jack; Characteristics such as volume is little, and maintenance easy for installation is easy extensively adopt for one times.The worm gear arrangement torsion spring of former import lifting motor is built in the worm gear, and rotates with worm gear.Because the stress effect of helix; When worm gear rotated, torsion spring can promote worm gear axial displacement play and swing, causes rocking of worm screw; Influence the stationarity and the effect of transmission, the worm gear arrangement of this money lifting motor has been improved the deficiency of above product on original basis.
Summary of the invention
The utility model technical problem to be solved is to above-mentioned prior art present situation; And provide a kind of worm gear arrangement of lifting motor, the worm gear arrangement of this a kind of lifting motor to adopt the external drive mechanism of stable transmission torsion spring, it is simple to have an assembling; Fundamentally solve play and swing when worm gear is worked in the prior art; Thereby avoid having improved structure simultaneously, production efficiency is significantly improved because of the change situation of accelerated wear test of gap, angle that transmission cooperates takes place.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of worm gear arrangement of lifting motor; Comprise the worm gear that is meshed with the worm shaft of lifting motor; And the worm gear supporting base that is used to assemble worm gear; It is characterized in that: worm gear is shaped on the annular boss that one links to each other, and is arranged with external torsion spring on the annular boss, and the stiff end of said external torsion spring is fixedly connected with the support of lifting motor.
For optimizing technique scheme, the measure of taking also comprises:
Above-mentioned annular boss is positioned at the bottom of worm gear, and corresponding with the top of said worm gear supporting base.
The height of above-mentioned annular boss is 6 to 15mm.
Above-mentioned external torsion spring is provided with the torsion spring cover outward, and the torsion spring cover is fixedly connected with the worm gear supporting base.
Above-mentioned worm gear supporting base and worm gear are respectively equipped with centre bore, in the centre bore of the centre bore of said worm gear and worm gear supporting base, are provided with central shaft.
Compared with prior art, the worm gear arrangement of a kind of lifting motor of the utility model adopts the structure of external torsion spring, makes the worm gear arrangement of lifting motor more succinct.The utility model has been cancelled torsion spring holder structure of the prior art, has reduced manufacturing procedure and assembly process, and external torsion spring is fixedly mounted on the electric machine support; One end fixing with electric machine support on; Torsion spring transfixion during transmission can not followed worm gear and rotated together, can not force worm gear when rotated because of receiving the external force effect play or the swing of peripheral torsion spring like this; Thereby ensured worm gear, worm geared high efficiency, prolonged the useful life of worm gear.The worm gear arrangement of a kind of lifting motor of the utility model has reduced the required precision of part, has improved cost performance of product, and concrete advantage is following:
1, torsion spring seat part of the prior art and finishing step thereof have been cancelled;
2, external torsion spring two ends is turned up, when having reduced external torsion spring and having made to the requirement of burr;
3, the worm gear shape is simplified, and has reduced the deflection and the required precision of worm gear moulding;
Operation had more easily improved the efficient of assembly quality and assembling when 4, external torsion spring assembled.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model embodiment;
Fig. 2 is the sectional structure sketch map of worm gear arrangement.
Embodiment
Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.
Fig. 1 is extremely shown in Figure 2 to be the structural representation of the utility model.
Reference numeral wherein is: lifting motor 1, worm shaft 11, support 12, worm gear 2, annular boss 21, worm gear supporting base 3, external torsion spring 4, stiff end 4a, torsion spring cover 5, central shaft 6.
As shown in Figure 1, the worm gear arrangement of a kind of lifting motor of the utility model comprises the worm gear 2 that is meshed with the worm shaft 11 of lifting motor 1, and the worm gear supporting base 3 that is used to assemble worm gear 2.
The worm gear 2 of the utility model is shaped on the annular boss 21 that one links to each other, and is arranged with external torsion spring 4 on the described annular boss 21, and the stiff end 4a of said external torsion spring 4 is fixedly connected with the support 12 of lifting motor 1.
In the present embodiment, the height of annular boss 21 is 6 to 15mm, and the height of annular boss 21 is preferably 10mm.The external diameter of the internal diameter of external torsion spring 4 and annular boss 21 adapts, and fit clearance is difficult for excessive.
Be provided with torsion spring cover 5 outside the external torsion spring 4, described torsion spring cover 5 is fixedly connected with worm gear supporting base 3.
Described worm gear supporting base 3 is respectively equipped with centre bore with worm gear 2, in the centre bore of the centre bore of said worm gear 2 and worm gear supporting base 3, is provided with central shaft 6.
The worm gear arrangement of a kind of lifting motor of the utility model, external torsion spring 4 are arranged on outside the annular boss 21 of worm gear 2, and the stiff end 4a of external torsion spring 4 is fixed on the support 12 of lifting motor.In the prior art, in worm gear when rotation, can be along the rotation of the torsion spring seat on the worm gear seat, thereby gives cooperating of play that worm gear one external force causes worm gear or swing influence and worm screw, and transmission efficiency is reduced greatly, quickens the wearing and tearing of worm gear simultaneously.The worm gear arrangement of the utility model has overcome defective of the prior art; With external torsion spring 4 external with worm gear 2 on; Saved the torsion spring seat; And the stiff end 4a of external torsion spring 4 is connected fixing with support 12, and external torsion spring 4 keeps motionless during worm gear 2 rotations, therefore can not cause external force and influence its transmission effect worm gear 2.
The most preferred embodiment of the utility model is illustrated, and various variations of being made by those of ordinary skills or remodeling can not break away from the scope of the utility model.
