Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1, the gear mechanism applied to the ultra-wide conveying device is formed by assembling a plurality of conveying chains 1 side by side, a plurality of gears 3 are sleeved on the same rotating shaft, and the rotating shaft is transversely distributed under the plurality of conveying chains 1, so that the plurality of gears 3 in the rotating shaft are sequentially meshed with the chain gears 2 distributed on the plurality of conveying chains 1 in the same horizontal direction in a clearance manner. The pivot and actuating mechanism electric connection, actuating mechanism set up to the motor in this embodiment, and the motor drives the pivot pivoted time, drives same a plurality of gears 3 synchronous rotations that rotate, and a plurality of gears 3 mesh with transfer chain 1 mutually, can promote many transfer chains 1 jointly and advance to realize super wide conveyor's transfer function.

As shown in fig. 2, h in fig. 2 is the tooth height, and s is the thickness of the tooth 4; a plurality of chain gears 2 are arranged on a single conveying chain 1 in the gear mechanism, intervals are arranged between every two adjacent chain gears 2, the distance between every two adjacent chain gears 2 is 1.2-1.5 times of the thickness of the top of each tooth 4, and the top of each tooth 4 can be clamped into the gap and can be ensured to rotate in enough space; and the teeth 4 of the gear 3 are clamped into the gaps of the sprocket 2 in the rotating process of the gear 3, and the transmission chain 1 can be driven to advance by the continuous rotation of the gear 3.

The tooth height of the tooth 4 is 1.5-2 times of the diameter of the chain gear 2, compared with the traditional gear 3, the tooth height of the tooth 4 in the embodiment is relatively high, the depth of the tooth 4 on the gear 3 clamped into the gap of the chain gear 2 can be increased, and the contact area of the tooth 4 and the chain gear 2 is increased when the tooth is rotated. If the tooth height of the tooth 4 is small, the meshing degree of the tooth 4 and the sprocket 2 is weak, and the transmission chain 1 cannot be normally pushed to advance; if the height of the teeth 4 is too large, the teeth 4 are likely to be broken after being stressed, and thus cannot be used normally. In the embodiment, the optimal proportion of the tooth height of the tooth 4 is that the tooth height of the tooth 4 is 1.8 times of the diameter of the sprocket 2, and multiple experiments show that the meshing degree of the gear 3 and the sprocket 2 is the highest and the error probability is the smallest under the proportion; as shown in fig. 2 and 3, in the tooth height ratio of the present embodiment, the tooth 4 starts to push the sprocket 2 forward at point a and is about to disengage from the sprocket 2 at point B, that is, the contact range of the tooth 4 with the sprocket 2 during rotation is from point a to point B; as shown in fig. 4, a conventional gear ratio is adopted, the tooth height is smaller than that of the present embodiment, and the contact range of the tooth 4 and the sprocket 2 in the rotation process is from a 'to B'; compared with the traditional gear 3, the contact range of the tooth 4 and the sprocket 2 is larger, the meshing degree is higher, and the matching degree of meshing transmission is improved, so that the transmission efficiency is improved, and the probability of meshing errors is reduced.

Because tooth 4 height of gear 3 increases for traditional gear 3 to some extent, in order to avoid tooth 4 atress fracture, set up the tooth width of gear 3 into the wheel shell width that is greater than or equal to sprocket 2, but make gear 3 and sprocket 2's atress evenly distributed, and increase tooth 4's thickness from gear 3 middle part to gear 3 root gradually, the thickness of 3 roots of gear has been increased under the condition that does not influence tooth 4 top meshing, can avoid tooth 4 root fracture, improve gear 3 life.

In order to increase the friction force between the side surfaces of the teeth 4 and the chain gear 2, the two side surfaces of the teeth 4, which are in contact with the chain gear 2, are provided with transverse grains, and the transverse grains are one of wavy grains, straight grains or dot grains, so that the slipping phenomenon of the gear 3 can be reduced.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
