[0027] Refer to the attached Figures 1-3 , a novel output coupling of a speed reducer and a splash-proof structure of a protective cover, including a box body 1. A coupling 2 is installed inside the box body 1, and a protective cover 3 is provided outside the box body 1. The protective cover 3 is fixedly connected to the box body 1 through a plurality of connecting bolts. A water discharge port 4 is opened at the lower part of the protective cover 3. The water discharge port 4 can be connected to a cold water collection area through a pipeline, which can prevent the cooling water from splashing and can also collect the cooling water well, so as to achieve the effect of preventing the cooling water from splashing and can also be reused, playing an energy-saving and emission-reduction effect.
[0028] In this embodiment, the coupling 2 is divided into an upper part and a lower part. A sealing baffle 5 is installed between the upper and lower parts of the coupling 2. A plurality of sealing rings 6 are provided at the connection between the sealing baffle 5 and the upper coupling 2. An upper internal gear ring 7 is provided on the outer side of the upper coupling 2, and a plurality of drain holes 8 are opened in the lower part of the side wall of the upper internal gear ring 7.
[0029] It should be noted that during the rolling operation, cooling water will flow down to the coupling 2 from the top of the upper coupling 2. By installing the sealing baffle 5 at the bottom of the upper coupling 2 and adding the sealing rings 6, 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 8 are opened in the lower part of the upper internal gear ring 7 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.
[0030] 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 input shaft of the ring rolling machine. The rolling work of the ring rolling machine is driven by transmitting the driving torque inside the reducer.
[0031] In this embodiment, a gland 9 is installed at the bottom of the upper coupling 2, and the gland 9 is fixed to the coupling 2 through a plurality of connecting bolts.
[0032] In this embodiment, a lower internal gear ring 10 is provided on the outer side of the lower coupling 2. The lower internal gear ring 10 and the upper internal gear ring 7 are connected and fixed through a plurality of precision reamed bolts. The upper internal gear ring 7 meshes and drives with the external gear sleeve on the output shaft of the reducer, and the lower internal gear ring 10 meshes and drives with the external gear sleeve on the input shaft of the ring rolling machine.
[0033] 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, and then the output shaft of the reducer is driven to rotate through the meshing of the two circular gears. The external gear sleeve on the output shaft of the reducer meshes with the lower internal gear ring 10, causing the lower coupling 2 to rotate. The connection between the lower internal gear ring 10 and the upper internal gear ring 7 makes it rotate, and the upper internal gear ring 7 meshes with the external gear sleeve on the input shaft of the ring rolling machine again, so as to transmit the driving torque to make the ring rolling machine perform the rolling work.
[0034] Working principle of the utility model: When the equipment is working, first connect the ring rolling machine and the speed reducer to both ends of the coupling 2 respectively. The ring rolling machine is not shown in the attached drawings. It should be noted that the motor of the speed 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 speed reducer is driven to rotate. The external gear sleeve on the output shaft of the speed reducer meshes with the lower internal gear ring 10, causing the lower coupling 2 to rotate. The connection between the lower internal gear ring 10 and the upper internal gear ring 7 makes it rotate. The upper internal gear ring 7 meshes with the external gear sleeve on the input shaft of the ring rolling machine, so as to transmit the transmission torque and make the ring rolling machine carry out the rolling work. During the rolling work, cold water flows down to the coupling 2 from the top of the upper coupling 2. By installing a sealing baffle 5 at the bottom of the upper coupling 2 and adding a sealing ring 6, 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 8 is opened at the lower part of the upper internal gear ring 7 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. During the drainage process, due to the centrifugal force, the cooling water splashes. When the cooling water is discharged, it will be thrown on the inner wall of the protective cover 3, and then discharged through the water discharge port 4 at the lower part of the protective cover 3. Connect the pipeline to the water discharge port 4 and the cold water collection area, and the discharged cold water can be transported to the inside of the cold water collection area, preventing the cooling water from splashing and collecting the cooling water well at the same time, so as to achieve the effect of preventing the cooling water from splashing and being reused, playing the role of energy conservation and emission reduction, and at the same time playing the role of protecting the coupling 2, making the on-site use safer.
[0035] The above embodiments only represent a certain implementation mode of the utility model, and its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent; it should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model; therefore, the protection scope of the utility model patent shall be subject to the appended claims.
