Description

Technical Field

[0001] The utility model belongs to the technical field of rail trains, and specifically relates to a universal shaft oil baffle. Background Technique

[0002] The universal shaft is a key component in the locomotive steering system. During operation, it needs to transmit a huge torque and at the same time adapt to complex steering movements. To ensure the normal operation of the universal shaft and extend its service life, it is usually necessary to lubricate it regularly. However, when the lubricating grease rotates at a high speed on the universal shaft, it is easy to be thrown out. Especially under high-speed operation or heavy-load conditions, the splashing of the grease will not only cause waste of the lubricant, but also contaminate the electrical equipment around the universal shaft, which may cause electrical failures or other safety hazards. Therefore, in order to prevent the grease from splashing and protect the surrounding equipment, an oil baffle is usually installed on the universal shaft to play a role of isolation and protection.

[0003] At present, the oil baffle has been widely used on the universal shaft, but there are still some deficiencies in its design and use. The maintenance process of the traditional oil baffle is relatively cumbersome. Usually, the entire oil baffle needs to be removed to clean or replace the grease. For the universal shaft that needs to be lubricated frequently, this disassembly process is both time-consuming and requires additional tools, and the maintenance work is inconvenient, which affects the operation efficiency of the equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a universal shaft oil baffle to solve at least one of the problems and defects mentioned in the above background technique.

[0006] A fixing plate body, the fixing plate body is hinged with the oil baffle main body through a plurality of hinges;

[0007] A limiting component, which includes a buckle lock and a lock catch. The buckle lock is arranged on the fixing plate, and a lock catch is connected to the side of the buckle lock away from the fixing plate, and the lock catch is fixedly connected to the oil baffle main body.

[0008] Furthermore, the oil baffle main body includes an oil baffle bent plate, circumferential reinforcing rib plates and longitudinal reinforcing rib plates. The oil baffle bent plate is hinged with the fixing plate body through a plurality of hinges. A plurality of circumferential reinforcing rib plates are arranged on the inner wall of the oil baffle bent plate, and a plurality of longitudinal reinforcing rib plates are arranged alternately on the plurality of circumferential reinforcing rib plates. The circumferential reinforcing rib plates enhance the circumferential strength of the oil baffle main body, and the longitudinal reinforcing rib plates further improve the overall strength of the oil baffle main body. Through the alternating arrangement of the circumferential reinforcing rib plates and the longitudinal reinforcing rib plates, the strength of the oil baffle main body in all directions has been significantly improved, and it can effectively resist stresses and vibrations from different directions.

[0009] Further, the fixed plate body includes a fixed plate bent plate and a fixed plate flange plate. The fixed plate bent plate is hinged to the oil baffle bent plate through a plurality of hinges. The oil baffle bent plate can be easily flipped when needed, and can firmly fit on the fixed plate bent plate in the fixed state, ensuring that the oil baffle bent plate remains stable during vehicle operation. The fixed plate flange plate is usually arranged at the outer edge part of the fixed plate bent plate for installing the entire fixed plate body on the bearing cover of the universal shaft.

[0010] Further, a sealing gasket is also arranged between the oil baffle bent plate and the fixed plate bent plate. The sealing gasket is located between the oil baffle bent plate and the fixed plate bent plate, forming an effective sealing interface.

By arranging a plurality of mounting holes corresponding to the mounting holes on the bearing cover on the fixed plate flange plate, there is no need to drill additional holes on the bearing cover, which simplifies the installation process of the oil baffle device.

[0013] Further, a plurality of mounting holes are arranged on a plurality of the fixed plate flange plates. By arranging a plurality of mounting holes corresponding to the mounting holes on the bearing cover on the fixed plate flange plate, there is no need to drill additional holes on the bearing cover, which simplifies the installation process of the oil baffle device.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The entire oil baffle main body is installed on the bearing cover of the universal shaft through the fixed plate body. When the universal shaft needs maintenance, the buckle lock of the limit component is unlocked from the lock, and then the locking between the oil baffle main body and the fixed plate body is released. The staff can pull the oil baffle main body to rotate downward through the hinge, which can provide space for lubricating the universal shaft and also clean the oil stains on the oil baffle main body.
