Example 1
As shown in fig. 1 to 2, the present embodiment provides a ring gear structure that can reduce manufacturing and maintenance costs, including:
the inner side of the ring body 1 is uniformly provided with wedge-shaped grooves in the circumferential direction, and teeth 2 are detachably connected in the wedge-shaped grooves;
the upper pressing ring 3 is connected to the upper part of the ring body 1, has a width larger than that of the ring body 1 and is used for fixing the teeth 2;
and the lower pressing ring 4 is connected to the lower part of the ring body 1, has a width larger than that of the ring body 1 and is used for fixing the teeth 2.
In the gear ring structure described in this embodiment, a wedge-shaped groove is formed in a ring body 1, teeth 2 are embedded and connected in the wedge-shaped groove of the ring body 1 through wedge angles, and when the teeth 2 are installed, an upper pressing ring 3 and a lower pressing ring 4 are respectively connected above and below the ring body 1, so that the teeth 2 are stably connected in the ring body 1, and are prevented from being loosened to influence normal operation; when the teeth 2 are partially worn, the upper pressing ring 3 and the lower pressing ring 4 are removed, and the worn teeth 2 are replaced independently. Through this embodiment the ring gear structure, when taking place wearing and tearing, only need to change tooth 2 of wearing and tearing, need not change whole ring gear structure, and only need adopt wear-resisting material and carry out thermal treatment to it to tooth 2, not only greatly reduced manufacturing cost, reduced the cost of later maintenance moreover.
