As shown in fig. 1, the reduction gear according to the embodiment of the first aspect of the present invention includes a box 100 and a mounting cover 200, a worm gear pair is disposed in the box 100, the worm gear pair includes a single-headed worm 310 and a worm wheel (not shown in the drawings), at this time, the box 100 and the worm gear pair can jointly form a worm gear reducer, and the single-headed worm 310 of the worm gear reducer and the worm wheel are driven by friction, so the worm gear reducer has a self-locking performance that other speed reducers lack, that is, the single-headed worm 310 can easily rotate the worm wheel, and the worm wheel is difficult to rotate the single-headed worm 310. However, it should be noted that not all worm gear reducers have the self-locking function, but the self-locking function of the worm gear reducers needs to be realized only by reaching a certain reduction ratio, and is related to the lead angle of the single-headed worm 310. According to the transmission characteristics of the worm gear, when the reduction ratio of the worm gear transmission pair exceeds 60, the worm gear transmission pair has strong self-locking force, therefore, the reduction ratio of the worm gear reducer of the utility model is between 60 and 100, and the larger the reduction ratio, the lower the transmission efficiency of the worm gear reducer, therefore, in the embodiment, the reduction ratio of the worm gear reducer is preferably 60.

Two first bearings 110 and two second bearings 120 are arranged in the box body 100, and the two first bearings 110 are respectively used for bearing two ends of the single-headed worm 310. The worm wheel key is connected with an output shaft 400, worm wheel mounting openings are formed in the front side wall and the rear side wall of the box body 100, end covers 500 which are detachably connected are arranged on the worm wheel mounting openings, two ends of the output shaft 400 are respectively mounted on the two end covers 500 through two second bearings 120, if the output shaft 400 is a hollow shaft, two ends of the output shaft 400 are respectively flush with the two end covers 500, and if the output shaft 400 is a solid shaft, at least one end of the output shaft 400 extends out of the end covers 500.

As shown in fig. 1 and 3, the mounting cover 200 is connected to the outer side surface of the box 100, the single-headed worm 310 extends into the mounting cover 200, a gear transmission pair is arranged in the mounting cover 200, the gear transmission pair includes a first gear 610 and a second gear 620, both the first gear 610 and the second gear 620 can be selected as spur gears, wherein the number of teeth of the second gear 620 is smaller than that of the first gear 610, the first gear 610 is in key connection with the single-headed worm 310, and the second gear 620 is in key connection with the input shaft 700.

The input shaft 700 is a main shaft of an external motor (not shown in the drawings), the motor is connected to the outer side surface of the mounting cover 200, and a motor bearing 710 for bearing the input shaft 700 is arranged in the motor, so that the motor can drive the single-headed worm 310 in a speed reducing manner, and at this time, the motor and the speed reduction transmission device together form a speed reduction motor. Because the work machine of the tile packaging equipment needs to adopt a speed reduction motor with the speed reduction ratio of 150-200, and because the worm gear speed reducer has the speed reduction ratio of 60-100, the speed reduction ratio of the gear transmission pair needs to be 2-3 in order to meet the speed reduction ratio requirement of the work machine. If the reduction ratio of the worm gear reducer is 60, the reduction ratio of the gear transmission pair is 2.5 to 3, at this time, the overall reduction ratio of the reduction motor is 150 to 180, if the reduction ratio of the worm gear reducer is 100, the reduction ratio of the gear transmission pair is 2, at this time, the overall reduction ratio of the reduction motor is 200.

In the prior art, in order to achieve the reduction ratio required by the working machine, the conventional reduction transmission device generally consists of two worm and gear transmission pairs with smaller reduction ratio (for example, i =10 × 15 or i =10 × 20), but in this case, the self-locking force of the reduction transmission device is weak, and the reduction transmission device needs to be used together with other one-way rotating mechanisms. And the utility model discloses a worm gear transmission of big reduction ratio is vice as reduction gearing's one-level transmission to be equipped with the gear transmission that the reduction ratio is less and to be regarded as the second grade transmission, will reduction gearing's reduction ratio is injectd between 150 to 200, thereby satisfies the technical requirement of big reduction ratio and strong self-locking power simultaneously, with adaptation in current ceramic tile equipment for packing.
