Description

Technical Field

[0001] This utility model relates to the field of axle box bearing technology, and in particular to a grease filling tool for axle box bearings. Background Technology

[0002] Axle box bearings are key components installed in the axle boxes of railway locomotives and rolling stock. They are used to connect the wheelsets to the bogies, support the weight of the vehicle, and ensure the flexible rotation of the wheelsets. Their performance directly affects the smoothness, safety, and reliability of train operation. They must have good wear resistance, impact resistance, and high temperature resistance to adapt to the complex loads and environmental conditions in railway transportation.

[0003] The axle box bearing grease filling fixture is a specialized device designed for filling axle box bearings of railway locomotives and rolling stock with lubricating grease. It is primarily used to precisely control the amount of grease added and ensure uniform grease distribution. Through an interface design adapted to the axle box structure and an automated or semi-automated operation mechanism, it achieves efficient and standardized grease filling operations. This effectively avoids the problems of measurement deviations and contamination risks associated with manual filling, ensuring the lubrication effect and service life of the axle box bearings. It is an important tool for improving maintenance efficiency and quality in railway vehicle maintenance. However, for large-scale production or scenarios requiring frequent filling, the filling speed of some fixtures cannot meet the requirements, especially manually operated fixtures, which have relatively low efficiency. In existing technologies, modular fixtures are selected, allowing for quick switching between different specifications by changing molds, reducing changeover time. However, grease containing metal shavings, dust, or gel-like substances can become stuck between the raceways and rollers after being injected into the bearing, thus reducing work efficiency.

The bottom of the scraper 308 is slidably connected to the top of the filter plate 3071.

[0032] A connecting pipe 13 is provided at the top rear side of the mounting box 1. The top of the connecting pipe 13 is connected to the bottom of the processing tank 302. A support column 12 is fixedly connected to the middle of the top rear side of the mounting box 1. A support plate 5 is installed at the top left rear side of the mounting box 1. Support rods 6 are fixedly connected to the front and rear ends of the bottom of the support plate 5. The second motor 301 can be stably installed through the installation of the support plate 5.

[0033] Specifically, the second motor 301 is started, which in turn drives the rotating rod 303 to rotate, causing the active bevel gear 304 to rotate accordingly. The active bevel gear 304 meshes with the driven bevel gear 306 for transmission. The driven bevel gear 306 drives multiple scrapers 308 to rotate synchronously through the telescopic rod 305 at the bottom. At the same time, the second connecting rope 3072 on the bottom left of the rotating rod 303 pulls the filter plate 3071 to move up and down. During the rotation, the scrapers 308 slide along the top of the filter plate 3071 to scrape off dirt.

The installation of the heat preservation ring 2082 prevents the internal temperature from dropping excessively.

[0035] Specifically, after the first motor 201 starts, its output end drives the rotating short column 210 to rotate, which in turn drives the driving gear 203 to rotate. The driving gear 203 meshes with the driven gear 202, causing the driven gear 202 to rotate at the top center of the reactor 211. At the same time, the threaded rod 204 at the bottom of the driven gear 202 rotates synchronously, causing the connecting rod 205 connected by the outer thread to move up and down along the threaded rod 204. The connecting rod 205 drives the outer scraper plate 209 to slide inside the reactor 211, effectively scraping away impurities from the inner wall of the reactor 211. In addition, the rotating rod 206 at the bottom of the threaded rod 204 and the multiple stirring rods 207 on its outer side also rotate, thoroughly mixing the material in the reactor 211. Meanwhile, the first connecting rope 2081 on the left side of the rotating short column 210 drives the bottom heat preservation ring 2082 to move, maintaining the temperature stability inside the reactor 211, thereby improving work efficiency.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The top of the mounting box 1 is fixedly connected to a mounting square plate 4. A control device 9 is installed on the front side of the top of the mounting square plate 4. Multiple buttons 10 are installed at equal intervals on the front side of the control device 9.

[0038] Working principle: The second motor 301 is turned on, which drives the rotating rod 303 to rotate, causing the active bevel gear 304 to rotate accordingly. The active bevel gear 304 meshes with the driven bevel gear 306 for transmission. The driven bevel gear 306 causes multiple scrapers 308 to rotate synchronously through the telescopic rod 305 at the bottom. At the same time, the second connecting rope 3072 on the bottom left of the rotating rod 303 drives the filter plate 3071 to move. During the rotation of the scrapers 308, they slide on the top of the filter plate 3071 to scrape off dirt. The filter plate 3071 filters the impurities generated during the processing, realizing the pretreatment of the device.

[0039] The first motor 201 starts, and its output end drives the rotating short column 210 to rotate, causing the driving gear 203 to rotate accordingly. The driving gear 203 meshes with the driven gear 202, thereby driving the driven gear 202 to rotate at the top center of the reactor 211. The threaded rod 204 at the bottom of the driven gear 202 rotates together, causing the connecting rod 205 connected by the outer thread to rise and fall along the threaded rod 204. The connecting rod 205 drives the outer scraper ring 209 to slide inside the reactor 211, scraping away impurities from the inner wall of the reactor 211. At the same time, the rotating rod 206 at the bottom of the threaded rod 204 and the multiple stirring rods 207 on its outer side rotate, stirring and mixing the materials inside the reactor 211. In addition, the first connecting rope 2081 on the left side of the rotating short column 210 drives the bottom heat preservation ring 2082 to move, maintaining the temperature inside the reactor 211 and thus improving working efficiency.
