Description

Technical Field

[0001] The utility model relates to the technical field of axle boxes, in particular to a split axle box. Background Art

[0002] In existing traditional axle box structures, an integral design is typically adopted, meaning that the various components of the axle box, such as the bearing seat, guide ring, and transmission device, are installed and used through fixed connections. The advantage of the integral axle box structure is that it is relatively simple and easy to manufacture, but it also has obvious limitations. For example, when the integral design needs to replace or adjust the bearing, it often requires the entire axle box to be disassembled. This is not only cumbersome to operate, but may also cause long-term equipment downtime, affecting its efficiency. At the same time, the traditional integral design lacks flexibility and is difficult to adapt to the installation requirements of different sizes and specifications.

[0003] In contrast, traditional axlebox structures often require different models to accommodate various mounting objects (such as bearings of varying sizes). This increases the number of spare parts and increases maintenance and management costs. Furthermore, due to the constraints of the overall design, adjustments can become difficult to make during precision assembly and transmission, compromising the transmission accuracy and stability of the device.

[0004] The existing technology lacks flexible assembly and disassembly mechanisms and adaptable transmission adjustment devices, making replacement and adjustment cumbersome and error-prone, making it difficult to meet the needs of multiple scenarios and specifications. In view of this, we have conducted research and improvements to address the existing problems and provide a split axle box to solve the current problems. The goal is to achieve the goal of solving the problems and improving the practical value of this technology. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] The following is combined with Figure 1-Figure 4 A split axle box provided by some embodiments of the present invention is described.

[0024] Example 1

[0025] This embodiment provides a split axle box, including: an axle box seat 100, a split axle clamp 200 and a bearing body 300. The split axle clamp 200 is fixedly installed on the inner side of the axle box seat 100, and a sealing ring 120 is provided on one side of the axle box seat 100 to prevent the internal components from loosening. The split axle clamp 200 includes a guide ring seat 210, a synchronous worm 220, a bearing clamp 230 and an adjustment tooth key 240. Among them, a fixed shaft sleeve 211 is fixedly installed on one side of the guide ring seat 210, and the synchronous worm 220 is rotatably installed on the inner side of the guide ring seat 210, so that the synchronous worm 220 can perform flexible transmission operations. The adjustment tooth key 240 is radially rotatably installed on the surface of the fixed shaft sleeve 211, and is meshed with one side of the synchronous worm 220 for transmission to achieve power transmission.

[0026] The surface of the guide ring seat 210 is provided with a slide groove 212, which allows the bearing clip 230 to be slidably installed inside the slide groove 212, ensuring a tight connection and flexible adjustment between the components. One side of the bearing clip 230 is provided with a worm tooth edge 231 that engages with the surface of the synchronous worm 220. The two sides of the synchronous worm 220 are respectively provided with a transmission tooth 221 for transmitting to the adjustment tooth key 240 and a worm rack 222 that engages with the worm tooth edge 231. These designs enable the bearing clip 230 to be adaptively adjusted under various working conditions, ensuring stable transmission. The inner side of the bearing clip 230 is also provided with a mounting groove for fixing the bearing body 300, making the installation and removal of the bearing body 300 easier.

[0027] In actual use, the rotation of the adjustment tooth key 240 will drive the corresponding movement of the bearing clip 230 through the meshing structure of the transmission tooth 221 and the spiral rack 222, thereby realizing effective control and adjustment of the bearing body 300, so that the equipment can maintain efficient operation in different application scenarios.

[0028] Example 2

[0029] This embodiment further optimizes Example 1, making the split axle box more efficient. In this embodiment, an adjustment hole 110 is defined on the surface of the axle box seat 100, and an adjustment key 240 is positioned corresponding to the adjustment hole 110. One end of the adjustment key 240 is provided with a hexagonal slot, facilitating precise adjustment through the adjustment hole 110. Specifically, by inserting a rotary tool into the adjustment hole 110, the adjustment key 240 can be rotated, facilitating quick adjustment and maintenance of various components.

[0030] In this embodiment, the structural design of the bearing clips 230 has been further optimized. Four bearing clips 230 are evenly distributed around the circumference to ensure the stability of the entire system during operation. The guide ring seat 210 has a cross-shaped slot 212, with the bearing clips 230 evenly spaced within the slots 212. This ensures smooth operation of the entire transmission system, eliminating eccentricity and improving transmission accuracy and efficiency.

[0031] In addition, in order to improve the lubrication effect, a number of flow grooves are provided on the surface of the fixed shaft sleeve 211, and flow holes for injecting lubricating oil are provided on the outer periphery of the fixed shaft sleeve 211, so that the lubricating oil can be evenly distributed in the entire transmission system, reducing friction loss between components and thus extending the service life of the equipment.

[0032] In this embodiment, the specifications of the worm rack 222 and worm tooth ridge 231 are optimized to form a flat spiral shape, resulting in smoother transmission engagement. Furthermore, the bearing clip 230 is designed as a fan-shaped structure with a central angle of less than or equal to 90 degrees, making it easier to assemble and disassemble with other components, thereby enhancing the flexibility and ease of use of the entire system.

[0033] As demonstrated in the two aforementioned embodiments, the split axlebox design of this utility model not only enables rapid assembly and disassembly of the bearing body 300 but also, through the interplay of various structures, makes transmission between the various components more flexible and efficient. In particular, improvements in lubrication and adjustment design significantly increase the service life and transmission stability of the entire device, making it suitable for a wide range of mechanical equipment applications.
