Description
Technical field
The present invention relates to a kind of gap adjusting device of worm and gear.
Background technique
Worm and gear is the mechanism being commonly used to motion between transmission two alternating axis and power, after long-time use, can because wearing and tearing produce gap for a long time between worm gear and worm screw, the generation in gap not only makes the transmission accuracy between worm gear and worm screw and intensity reduce, also can reduce the working life of worm and gear, also can there is security incident in serious.
Summary of the invention
The object of the invention is to provide a kind of gap adjusting device regulating gap between worm gear and worm screw.
A gap adjusting device for worm and gear, comprises
The bearing be connected with worm screw,
To be arranged on worm screw and the second bevel gear near described bearing side,
Be arranged on the wheel shaft on described bearing,
To be arranged on described wheel shaft and the first bevel gear be connected with a joggle with described second bevel gear,
Be arranged on the difference clutch that on described wheel shaft and lower end and described first bevel gear upper end are connected with a joggle,
And be arranged on the tune gap worm screw that on described wheel shaft and lower end and described difference clutch upper end be connected with a joggle,
Described tune gap worm screw and described worm gear are connected with a joggle,
The number of gears of described difference clutch upper-end surface and the number of gears of lower end surface unequal.
In the present invention, the described difference clutch upper-end surface number of gears differs 1 ~ 3 with the lower end surface number of gears, and preferably, the described difference clutch upper-end surface number of gears differs 1 with the lower end surface number of gears.
In the present invention, the outer surface of described bearing is provided with packing ring.
In the present invention, the angle of described worm screw and described tune gap worm screw is greater than 0 ° and is less than or equal to 90 °, and preferably, the angle of described worm screw and described tune gap worm screw is 90 °.
The beneficial effect that the present invention has: when having gap between worm gear and worm screw, closing machine, first screw out and adjust gap worm screw to make it to separate with difference clutch, then one or several tooth of rotary difference clutch, finally screw in and adjust gap worm screw engaging with difference clutch, due to difference clutch upper and lower end face the number of teeth not etc., therefore tune gap worm screw and the first bevel gear angle of rotating is not etc., namely the angle adjusting gap worm screw and worm screw to rotate not etc., does not achieve the object of adjusting play.This gap adjusting device structure is simple, stable, and position is adjustable, easy to operate, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of gap adjusting device of the present invention;
Fig. 2 is the structural representation of difference clutch in the present invention;
Fig. 3 is for adjusting gap principle schematic.
Embodiment
Below in conjunction with embodiment, the invention will be further described, but protection scope of the present invention is not only confined to embodiment.
As shown in Figure 1, a kind of gap adjusting device of worm and gear, comprise bearing 5, wheel shaft 9, adjust gap worm screw 8, difference clutch 7, first bevel gear 6 and the second bevel gear 3, one end of wheel shaft 9 is arranged on bearing 5, bearing 5 is connected with worm screw 2, second bevel gear 3 is arranged on the one end near bearing 5 on worm screw 2, first bevel gear 6 to be arranged on wheel shaft 9 and to be connected with a joggle with the second bevel gear 3, difference clutch 7 to arrange on wheel shaft 9 and is positioned at the upper end of the first bevel gear 6, the lower end of difference clutch 7 and the upper end of the first bevel gear 6 are connected with a joggle, adjust gap worm screw 8 to be arranged on wheel shaft 9 and be positioned at the upper end of difference clutch 7, the lower end of gap worm screw 8 and the upper end of difference clutch 7 is adjusted to be connected with a joggle, the side of gap worm screw 8 and worm gear 1 is adjusted to be connected with a joggle, the outer surface of bearing 5 is provided with packing ring 4, the angle of worm screw 2 and tune gap worm screw 8 is greater than 0 ° and is less than or equal to 90 °, most preferably 90 °, namely adjust gap worm screw 8 mutually vertical with worm screw 2.
Continue with reference to shown in Fig. 2, the number of teeth of difference clutch 7 upper-end surface is unequal with the number of teeth of lower end surface, and differs 1 ~ 3, in the present embodiment, many 1 of the number of teeth of the gear ratio lower end surface of difference clutch 7 upper-end surface, the upper-end surface number of teeth is 25, and the lower end surface number of teeth is 24.Certainly, also can be that the number of teeth of gear ratio lower end surface of upper-end surface is few.
Shown in composition graphs 1 and Fig. 3, worm gear 1 and worm screw 2 can produce gap after wearing and tearing for a long time, during adjusting play, closing machine, screw off and adjust gap worm screw 8, tune gap worm screw 8 is separated with difference clutch 7, then clockwise or be rotated counterclockwise difference clutch 7 one teeth or several tooth, until the side of the gear teeth and worm screw 2 fit tightly on worm gear 1, finally screw in and adjust gap worm screw 8, after screw-in adjusts gap worm screw 8, worm gear 1 can be driven to rotate, but due to difference clutch 7 upper and lower end face the number of teeth not etc., therefore the angle adjusting gap worm screw 8 and the first bevel gear 6 to rotate is not etc., namely the angle adjusting gap worm screw 8 and worm screw 2 to rotate is not etc., achieve the object of adjusting play.Continue with reference to shown in Fig. 3, if worm gear 1 rotates clockwise, the left side and the worm screw 2 that are then adjusted to the gear teeth on worm gear 1 fit tightly, in like manner, if worm gear 1 rotates counterclockwise, then the right side and the worm screw 2 that are adjusted to the gear teeth on worm gear 1 fit tightly, therefore, according to the direction that worm gear 1 rotates, as long as ensure that the side of the gear teeth on worm gear 1 and worm screw 2 fit tightly.
Last it is noted that above embodiment only in order to illustrate the present invention and and unrestricted technological scheme described in the invention, therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, but, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, and all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in right of the present invention.
