Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

As shown in the figure, the double-shaft rotary speed reducer comprises a pitching box body 1 and a horizontal box body 2, wherein the pitching box body 1 is vertically installed on the horizontal box body 2 through an installation frame 21, a pitching worm wheel 5, a pitching worm 4 and a pitching motor 3 are arranged on the pitching box body, the pitching worm wheel 5 is meshed with the pitching worm 4, the pitching motor 3 provides power input to drive the pitching worm 4 to rotate, and therefore the pitching worm wheel 5 is pushed to rotate, the worm wheel rotation power output is achieved, and the pitching angle of equipment is controlled; horizontal worm wheel 8, horizontal worm 7 and horizontal motor 6 are equipped with on the horizontal box 2, horizontal worm wheel 8 meshes with horizontal worm 7, horizontal motor 6 provides power input and can drives horizontal worm 7 and rotate to promote horizontal worm wheel 8 to rotate, drive equipment horizontal rotation. Sliding bearings 9 used for transmission output are arranged between the pitching worm wheel 5 and the pitching box body 1 and between the horizontal worm wheel 8 and the horizontal box body 2, and the sliding bearings 9 are fixed on the box body.

In this embodiment, slide bearing 9 is L shape, and L shape slide bearing can the adaptation every single move worm wheel 5 and every single move between the box 1, the clearance between horizontal worm wheel 8 and the horizontal box 2, laminates better, and transmission efficiency is higher.

In this embodiment, oil seals 10 are respectively arranged between the pitch worm wheel 5 and the pitch box body 1 and between the horizontal worm wheel 8 and the horizontal box body 2 to prevent grease from leaking, and a sealing ring 11 is further arranged between the pitch worm wheel and the pitch box body to further enhance the sealing performance.

In this embodiment, the pitching box 1 is provided with a mark point 13 for marking the rotation angle of the pitching worm gear 5, the initial position of the mark point is located right above the central point of the pitching box, which is represented as the initial 0 ° position, and when the pitching worm gear 5 rotates, the mark point 13 also rotates.

In the embodiment, the meshing parts of the pitching worm wheel 5 and the pitching worm 4 and the horizontal worm wheel 8 and the horizontal worm 7 are provided with the lubricating grease filling port 12, the meshing parts of the worm wheel and the worm are worn most seriously, lubricating grease needs to be filled frequently, the lubricating grease filling port 12 can be used for conveniently filling lubricating grease, and the efficiency is improved.
