[0025] Referring to the attached Figure 1-2 , a waterproof structure for the output coupling of a new type of speed reducer, comprising a box body 1. A coupling 2 is installed inside the box body 1. The coupling 2 is divided into an upper part and a lower part. A sealing baffle 3 is installed between the upper part and the lower part of the coupling 2. A plurality of sealing rings 4 are provided at the connection between the sealing baffle 3 and the upper coupling 2. An upper internal gear ring 5 is provided on the outer side of the upper coupling 2. A plurality of drain holes 6 are opened in the lower part of the side wall of the upper internal gear ring 5. During the rolling operation, cold water will flow down to the coupling 2 at the top of the upper coupling 2. By installing a sealing baffle 3 at the bottom of the upper coupling 2 and adding sealing rings 4, it can effectively prevent the cooling water from invading the lower coupling 2, achieving the protection of the lower coupling 2. At the same time, drain holes 6 are opened in the lower part of the upper internal gear ring 5 of the upper coupling 2. During the working process, the cooling water invading the inside of the coupling 2 is discharged to the outside of the coupling 2 through its own rotational centrifugal force, thereby achieving the effect of reducing the water intrusion inside the coupling 2.

[0026] In this embodiment, one end of the coupling 2 is connected to the output shaft of the reducer, and the other end of the coupling 2 is connected to the ring rolling machine. The transmission torque is transmitted through the reducer to drive the ring rolling machine to perform the rolling work.

[0027] In this embodiment, a gland 7 is installed at the bottom of the upper coupling 2, and the gland 7 is fixed to the coupling 2 through a plurality of connecting bolts.

[0028] In this embodiment, a lower internal gear ring 8 is provided on the outer side of the lower coupling 2. The lower internal gear ring 8 and the upper internal gear ring 5 are connected and fixed through a plurality of precision reamed holes bolts. The upper internal gear ring 5 meshes with the external gear sleeve on the output shaft of the reducer, and the lower internal gear ring 8 meshes with the external gear sleeve on the input shaft of the ring rolling machine.

[0029] It should be noted that the motor of the reducer drives the rotation of the first rotating shaft through the transmission of two bevel gears. Due to the meshing of the two circular gears, the second rotating shaft rotates. Then, through the meshing of the two circular gears, the output shaft of the reducer is driven to rotate. The external gear sleeve on the output shaft of the reducer meshes with the lower internal gear ring 8, causing the lower coupling 2 to rotate. The connection between the lower internal gear ring 8 and the upper internal gear ring 5 makes it rotate. The upper internal gear ring 7 also meshes with the external gear sleeve on the input shaft of the ring rolling machine, so as to transmit the transmission torque to make the ring rolling machine perform the rolling work.

[0030] The working principle of the present utility model: When the equipment is working, first connect the ring rolling machine and the reducer to the two ends of the coupling 2 respectively (the ring rolling machine is not shown in the attached drawings). The motor of the reducer drives the rotation of the first rotating shaft through the transmission of two bevel gears. Due to the meshing of the two circular gears, the second rotating shaft rotates. Then, through the meshing of the two circular gears, the output shaft of the reducer is driven to rotate. The external gear sleeve on the output shaft of the reducer meshes with the lower internal gear ring 8, causing the lower coupling 2 to rotate. The connection between the lower internal gear ring 8 and the upper internal gear ring 5 makes it rotate. The upper internal gear ring 5 also meshes with the external gear sleeve on the input shaft of the ring rolling machine, so as to transmit the transmission torque to make the ring rolling machine perform the rolling work. When performing the rolling work, cold water will flow down to the coupling 2 from the top of the upper coupling 2. By installing a sealing baffle 3 at the bottom of the upper coupling 2 and adding a sealing ring 4, it can effectively prevent the cooling water from invading the lower coupling 2, realizing the protection of the lower coupling 2. At the same time, a drainage hole 6 is opened at the lower part of the upper internal gear ring 5 of the upper coupling 2. During the working process, the cooling water invading the inside of the coupling 2 is discharged to the outside of the coupling 2 through its own rotational centrifugal force, so as to achieve the effect of reducing the water intrusion inside the coupling 2.

[0031] The above-described embodiments merely represent certain implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
