Description

Technical Field

[0001] The utility model relates to the technical field of peripheral transmission concentrators, and more specifically to an automatic oiling device for a rotary bearing of a peripheral transmission concentrator. Background Art

[0002] The concentrator slewing bearing is a key mechanical component on a peripheral drive concentrator, primarily used to support the rotating portion of the concentrator. Because peripheral drive concentrators must withstand significant loads and friction during operation, the performance and stability of the slewing bearing are crucial to ensuring proper operation. As an essential component of the support and transmission system, the slewing bearing must be kept in good lubrication to minimize friction, reduce wear, and increase transmission efficiency and service life.

[0003] After searching, it was found that the document with publication number CN217736054U discloses a slewing bearing oiling workbench and oiling equipment. In this document, the driving gear drives the slewing bearing to rotate. Although oil can be injected into the slewing bearing surface through the oiling device, the oiling device does not directly spray oil onto the meshing point between the slewing bearing and the driving gear, but faces the slewing bearing surface. Therefore, it is impossible to directly and quickly lubricate the slewing bearing and the driving gear. At the same time, the oiling device is driven externally to inject oil, which consumes a lot of energy. Therefore, we propose an automatic oiling device for the slewing bearing of a peripheral transmission concentrator. Utility Model Content

[0004] The utility model provides an automatic oiling device for a slewing bearing of a peripheral transmission concentrator.

[0005] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: an automatic oil filling device for a slewing bearing of a peripheral transmission concentrator, comprising a half gear and a transmission gear, the half gear and the transmission gear being meshed with each other, a connecting shaft being fixedly provided on the inner wall of the transmission gear, a swing arm being fixedly provided on the circumferential outer wall of the connecting shaft, and a fixing rod being fixedly provided on the top of the outer end of the swing arm.

[0006] Preferably, an output shaft is fixedly provided on the inner wall of the half gear, and a driving gear is fixedly provided on the circumferential outer wall of the output shaft, and the driving gear is located above the half gear.

[0007] Preferably, a mounting seat is further included, wherein a slide is slidably connected to the inner wall of the mounting seat, a support plate is fixedly provided on the outer side of the slide, and the outer end of the support plate is a semicircular structure.

[0008] Preferably, an oil storage tank is fixedly provided on the top of the mounting seat, a connecting pipe is fixedly provided on the top of the oil storage tank, a fixing plate is fixedly provided on the inner wall of the mounting seat, a pressure cylinder is fixedly provided on the inner wall of the fixing plate, an oil inlet pipe is fixedly provided on the top of the outer wall of the pressure cylinder, the top of the oil inlet pipe is connected and fixed to the connecting pipe, a second one-way valve is fixedly provided on the circumferential outer wall of the oil inlet pipe, a fuel nozzle is fixedly provided on the end of the pressure cylinder, and a first one-way valve is fixedly provided on the circumferential outer wall of the fuel nozzle.

[0009] Preferably, the inner wall of the pressure cylinder is slidably connected to a piston, the outer wall of the piston is fixed with a connecting rod, the end of the connecting rod passes through the pressure cylinder and is slidably connected thereto, and a spring is sleeved on the circumferential outer wall of the connecting rod.

[0010] Preferably, one end of the spring is connected and fixed to the inner wall of the pressure cylinder, and the other end of the spring is connected and fixed to the piston.

[0011] The beneficial effects of the present invention are:

[0012] 1. The automatic oil filling device of the slewing bearing of the peripheral transmission concentrator is designed. The fixed rod detaches from the support plate during the rotation process. Under the elastic force of the spring, the piston slides in the opposite direction along the inner wall of the pressure cylinder. At this time, suction is generated inside the pressure cylinder, and the lubricating oil inside the oil storage tank is sucked into the interior through the oil inlet pipe and the connecting pipe. When the support plate moves, it can push the connecting rod to move, and the connecting rod pushes the piston to slide along the inner wall of the pressure cylinder. At this time, the spring is stretched, and when the piston moves, the lubricating oil inside the pressure cylinder is sprayed out through the oil nozzle to the meshing point of the slewing bearing and the drive gear, thereby reducing the friction between the drive gear and the slewing bearing.

[0013] 2. The automatic oiling device for the slewing bearing of the peripheral transmission concentrator is driven by an external drive motor to rotate the output shaft, which in turn drives the drive gear and the half gear to rotate simultaneously. The drive gear drives the slewing bearing to rotate, which in turn drives the transmission gear to rotate intermittently through the half gear. The transmission gear drives the swing arm to rotate through the connecting shaft. The bottom of the connecting shaft is rotatably connected to the workbench. The fixed rod is driven to rotate through the swing arm, which squeezes the support plate through the fixed rod. This design can drive the oiling device to operate through the output shaft, thereby achieving intermittent oil injection and reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed rod 7 is separated from the support plate 10 during the rotation process.

The fixed rod 7 detaches from the support plate 10 during the rotation process. Under the elastic force of the spring 15, the piston 13 slides in the opposite direction along the inner wall of the pressure cylinder 21.
