[0002] At present, most of the mounting screws on the reducer case are installed on the outside of the reducer case, and if the driven reel rotates, the reducer case also needs to rotate. When the mounting screws need to be installed inside the reducer case, screw holes corresponding to the number of mounting screws need to be drilled on the outside of the reducer case so that all the mounting screws can be installed inside the reducer case. However, the number of screw holes in the reducer case is too large, which makes the strength of the reducer case small and cannot meet the actual production requirements. Utility Model Content

[0003] In view of this, in order to solve the above problems, the purpose of the utility model is to provide a rotary jack reducer mounting screw structure, which includes:

[0007] The pinion gear, the large gear and the reducer input shaft are all installed in the reducer housing;

[0008] One end of the reducer housing is circumferentially provided with a plurality of screw plug holes, any of which can be coaxially arranged with any of the mounting holes, and a plurality of the built-in mounting screws can be inserted into the screw plug holes, pass through the mounting holes and extend out of the other end of the reducer housing, so that the mounting flange of the large gear and the external equipment drum can be installed through the plurality of the built-in mounting screws.

[0009] In the above-mentioned rotating socket reducer mounting screw structure, each of the small gears and each of the reducer input shafts form a group of transmission structures, and a transmission structure is respectively provided at both ends of the large gear.

[0010] The above-mentioned rotary socket reducer mounting screw structure, wherein the large gear axial array is provided with twenty-four mounting holes.

[0011] The above-mentioned rotary jack method reducer mounting screw structure, wherein the reducer housing is provided with six screw plug holes in an annular array.

[0012] The above-mentioned rotary jack method reducer mounting screw structure further includes: a screw plug, and each of the screw plug holes is correspondingly installed with a screw plug.

[0013] The above-mentioned rotating socket reducer mounting screw structure further includes: a motor; one end of each reducer input shaft extends out of the reducer housing and is installed on the motor, and the motor drives the reducer input shaft to rotate.

[0014] In the above-mentioned rotary socket reducer mounting screw structure, the reducer input shaft is mounted on the reducer housing through a bearing seat.

[0015] Compared with the prior art, the above technical solution has the following positive effects:

[0016] Through the application of the utility model, a rotary jack reducer mounting screw structure is provided, in which the built-in mounting screws are installed inside the reducer case, and when the motor drives the reducer input shaft to rotate, the reducer input shaft drives the external equipment reel to rotate through the small gear and the large gear.
