Description

Technical Field

[0001] The utility model relates to the technical field of joints, and specifically relates to a rotary joint for an RH gunning machine. Background Technique

[0002] During the operation of the RH gunning machine, the rotary joint plays a crucial role. However, in the past technologies, the rotary joint has faced a series of challenges.

[0003] In the industrial field, the gunning operation usually needs to be carried out under high temperature, high pressure and complex working conditions. In such a harsh environment, traditional rotary joints often have leakage problems due to poor sealing effects. Leakage not only causes waste of gunning materials, but also may affect product quality and production efficiency.

[0004] At the same time, due to the unreasonable structure of some rotary joints, the cooperative working effect between components is poor. Under the operating conditions of high-speed rotation and frequent start-stop, they are prone to wear, looseness and even damage, resulting in frequent shutdowns of the equipment for maintenance, increasing production costs and maintenance workload.

[0005] To sum up, developing a rotary joint for an RH gunning machine with excellent performance, stability and reliability has become an urgent need in industrial production. Content of the Utility Model

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] As Figure 1-2 shown, a rotary joint for an RH gunning machine proposed in an embodiment of the present utility model includes a lower joint 1 and an upper joint 5. The lower joint 1 and the upper joint 5 are inserted. A felt ring 9 is sleeved inside the lower joint 1 on the surface of the upper joint 5. A gasket 6 is sleeved on the upper joint 5 on one side of the felt ring 9. A shaft circlip 7 is sleeved on one side of the gasket 6. A deep groove ball bearing 8 is sleeved on one side of the shaft circlip 7. A VA seal 4 is sleeved at the connection between the lower joint 1 and the upper joint 5;

[0025] This rotary joint for the RH gunning machine is mainly composed of a lower joint 1 and an upper joint 5. The two are connected by insertion, which is convenient for installation and disassembly and can ensure the stability of the connection, thus realizing stable rotary motion. The inner part of the lower joint 1 is sleeved on the surface of the upper joint 5, and a felt ring 9, a gasket 6, a shaft circlip 7 and a deep groove ball bearing 8 are arranged in sequence. The felt ring 9 plays a preliminary role in sealing and dust prevention; the gasket 6 increases the flatness and stability of the contact part; the shaft circlip 7 axially positions and fixes components such as the gasket 6; the deep groove ball bearing 8 reduces friction and wear during rotation. The VA seal ring 4 sleeved at the connection between the lower joint 1 and the upper joint 5, and the O-ring seal 2 sleeved on the lower joint 1 through a notch, the multiple sealing structure effectively prevents medium leakage during the gunning process and ensures the accuracy and efficiency of the gunning operation. The hole on the lower joint 1 fixes the upper joint 5 through an inner hexagon socket head cap screw 3, enhancing the reliability of the connection between the upper and lower joints 1 and enabling it to withstand various stresses and loads during work.

[0026] As Figure 2 shown, in some embodiments, the O-ring seal 2 is sleeved on the lower joint 1 through a notch; the O-ring seal 2 is sleeved through the notch on the lower joint 1, and this sleeving method is relatively convenient for installation.

[0027] As Figure 2 shown, in some embodiments, there are holes on the lower joint 1, and the inner hexagon socket head cap screw 3 is connected through the holes to fix the upper joint 5; the holes on the lower joint 1 provide an installation position for the inner hexagon socket head cap screw 3. The inner hexagon socket head cap screw 3 is connected to the upper joint 5 through these holes, and a firm fixing effect can be achieved.

[0028] As Figure 2 shown, in some embodiments, the inner and outer rings of the deep groove ball bearing 8 are respectively in contact with the upper joint 5 and the lower joint 1; the deep groove ball bearing 8 is a common and excellent-performance rolling bearing. Its inner and outer rings are respectively in contact with the upper joint 5 and the lower joint 1, which can significantly reduce the frictional resistance during rotation and make the rotary motion smoother and more stable.

[0029] As Figure 2 shown, in some embodiments, the lower joint 1 is provided with positions for installing the felt ring 9, the gasket 6, the shaft circlip 7 and the deep groove ball bearing 8, and can be shape-adapted to the upper joint 5; the specific installation positions inside the lower joint 1 provide an accurate installation space for the felt ring 9, the gasket 6, the shaft circlip 7 and the deep groove ball bearing 8, ensuring that these components can be in their proper positions and work together. This precise installation layout helps to improve the compactness and stability of the structure.

[0030] Moreover, the lower joint 1 can be adapted to the shape of the upper joint 5, which means that the two can fit closely when connected, reducing gaps and deviations, thereby improving the sealing performance and the rotation accuracy.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
