Description

Technical Field

[0001] This utility model relates to the field of shaft support technology, and in particular to a shaft support for supporting and fixing rotation. Background Technology

[0002] In mechanical transmission systems, the support and fixation of rotating shafts are crucial for ensuring the stable operation of the entire system. Shaft supports, as important components for supporting and fixing rotating shafts, primarily function to maintain the shaft's correct positioning and stability during operation, while simultaneously transmitting radial and axial loads and preventing axial displacement due to vibration or off-center loading, thereby ensuring the accuracy and reliability of the mechanical transmission.

[0003] However, traditional shaft supports present numerous problems in practical applications. Regarding lubrication, most traditional shaft supports rely on lubricating oil to reduce frictional resistance, but the use of lubricating oil brings a series of drawbacks. On the one hand, lubricating oil is easily affected by external environmental factors, such as high temperatures and dust, leading to performance degradation or even failure, requiring regular refilling and maintenance. This not only increases maintenance costs and operational complexity but may also cause equipment failure due to untimely maintenance. On the other hand, lubricating oil may age or leak during use, polluting the surrounding environment and potentially corroding mechanical components, reducing the overall reliability of the system.

[0004] In terms of structural design and connection methods, traditional shaft supports often fail to ensure a secure connection and precise alignment between components, making them prone to loosening or misalignment during operation, affecting the shaft's positioning accuracy and stability. Furthermore, traditional shaft supports have unreasonable load distribution, easily leading to localized stress concentration and shortening the equipment's lifespan, especially under high-load and high-speed operating conditions. Moreover, traditional shaft supports are relatively large and lack compactness, making them unsuitable for applications with limited installation space. Utility Model Content

[0042] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0043] Please refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a shaft support for supporting and fixing rotation, comprising: a mounting base 1, bushing assemblies 2 for shaft support mounting which are detachably mounted at both ends of the mounting base 1, and a support assembly 3 for shaft positioning mounted at the center of the mounting base 1.

[0044] By adopting the above technical solution, the self-lubricating oilless bushing 201 eliminates the need for additional lubricating oil, reducing friction and avoiding contamination and lubricating oil failure risks, thus improving system reliability. The oilless bushing 201 is secured with cross-slot pan head screws 2021², ensuring a firm connection and precise alignment of components, making the structure stable and safe. The oilless bushing 201 eliminates the need for frequent lubrication maintenance, reducing maintenance costs and operational complexity. The shaft support features two bushing assemblies 2 and a support assembly 3 between them, evenly distributing the shaft's operating load, reducing localized stress concentration, extending equipment life, and maintaining stability even under high loads and high speeds. The compact structure saves space, meeting mechanical transmission requirements and adapting to space-constrained applications. The oilless bushing 201 and support 301 are easy to disassemble and assemble, facilitating maintenance and replacement. The overall design has a wide range of applications, reducing system operating costs and maintenance difficulty.

[0045] To facilitate precise installation of the oil-free bushing 201, in this embodiment: the bushing assembly 2 includes the oil-free bushing 201, and the mounting base 1 has a bushing mounting hole 2011 that matches the position of the oil-free bushing 201. The design of the bushing mounting hole 2011 matching the oil-free bushing 201 provides a precise installation position for the oil-free bushing 201, which can ensure that the oil-free bushing 201 is quickly and accurately positioned during the installation process, avoid installation deviation, and thus ensure the overall performance and stability of the shaft support.

[0046] To facilitate the installation of the oil-free bushing 201 and prevent scratches, in this embodiment, the edge of the bushing mounting hole 2011 is chamfered. This chamfered design serves as a guide during installation, making it easier to insert the oil-free bushing 201 into the bushing mounting hole, thus improving installation efficiency. Simultaneously, the chamfered edge effectively prevents scratches on the surface of the oil-free bushing 201 during installation, protecting its integrity and extending its service life.

[0047] To ensure the secure fixing of the oil-free bushing 201, in this embodiment: the end of the oil-free bushing 201 is fixedly connected to a bushing mounting shoulder 202 for fixing the oil-free bushing 201. The bushing mounting shoulder 202 is provided with two cross-slot pan head screws 2021. The side of the mounting base 1 and the position corresponding to the cross-slot pan head screws 2021 are provided with mounting screw holes 2022 that match the cross-slot pan head screws 2021. Through the design of the bushing mounting shoulder 202 and the cross-slot pan head screws 2021, the oil-free bushing 201 can be securely fixed on the mounting base 1, preventing the oil-free bushing 201 from loosening or shifting during shaft operation, ensuring the positioning accuracy and stability of the shaft, and improving the reliability of the shaft support.

[0048] To protect the Phillips head pan head screw 2021 and improve its aesthetics, in this embodiment, a screw receiving groove 203 is provided on the bushing mounting shoulder 202 at the position corresponding to the Phillips head pan head screw 2021. The screw receiving groove 203 conceals the Phillips head pan head screw 2021, preventing it from protruding from the surface of the bushing mounting shoulder 202 and being subjected to external impacts or scratches, thus protecting the screw's integrity. Simultaneously, this design also enhances the overall aesthetics of the shaft support, making the structure more compact and orderly.

[0049] To enhance sealing and prevent impurities from entering the oil-free bushing 201, in this embodiment, sealing rings 204 are provided on the edges of the shaft holes of both the oil-free bushing 201 and the bushing mounting shoulder 202. The sealing rings 204 can effectively prevent external dust, moisture and other impurities from entering the interior of the oil-free bushing 201, avoiding wear on the friction surfaces between the shaft and the oil-free bushing 201 caused by impurities, thereby extending the service life of the oil-free bushing 201 and the shaft, and ensuring the normal operation of the shaft support in harsh environments.

[0050] To ensure the coaxiality between the support base 301 and the oil-free bushing 201 and improve operational accuracy, in this embodiment, the support assembly 3 includes a support base 301, on which a support shaft hole 3011 is provided. The support shaft hole 3011 is coaxial with the shaft hole of the oil-free bushing 201. The coaxial design of the support shaft hole 3011 and the shaft hole of the oil-free bushing 201 ensures that the shaft maintains linear motion when passing through the oil-free bushing 201 and the support base 301, improves the operational accuracy of the shaft, reduces vibration and wear caused by shaft misalignment, and ensures the stability and reliability of mechanical transmission.

[0051] In order to achieve precise positioning and installation of the support 301, in this embodiment, the mounting base 1 is also provided with a mounting groove 302 for matching the support 301. The mounting groove 302 provides a precise installation position for the support 301, which enables the support 301 to be positioned quickly and accurately during the installation process, avoiding installation deviations, thereby ensuring the fitting accuracy between the support assembly 3 and the bushing assembly 2, and improving the overall performance of the shaft support.

[0052] To ensure the support base 301 is securely installed and easy to disassemble, in this embodiment: two symmetrically arranged positioning posts 303 are fixedly connected to the bottom of the support base 301; positioning grooves 3031 matching the positioning posts 303 are provided on the inner wall of the mounting groove 302; and mounting bolts 3032 for fixing the positioning posts 303 are provided at the bottom of the mounting base 1. The cooperation of the positioning posts 303 and the positioning grooves 3031 ensures that the support base 301 is accurately and securely positioned in the mounting groove 302, preventing the support base 301 from shaking or shifting during operation. At the same time, the design of the mounting bolts 3032 makes the disassembly and assembly of the support base 301 more convenient, facilitating subsequent maintenance and replacement operations.

[0053] The working principle of this utility model is as follows:

[0054] First, during installation, align the oil-free bushing 201 with the bushing mounting hole 2011 on the mounting base 1. Due to the chamfered edge of the bushing mounting hole 2011, the oil-free bushing 201 can be easily inserted and quickly positioned. Next, using the two Phillips head pan screws 2021 on the bushing mounting shoulder 202, screw them into the corresponding mounting screw holes 2022 on the side of the mounting base 1, firmly fixing the oil-free bushing 201 to the mounting base 1. At this point, the Phillips head pan screws 2021 are hidden within the screw receiving groove 203 of the bushing mounting shoulder 202, protecting the screws and improving aesthetics. Simultaneously, the sealing rings 204 on the edges of the shaft holes of the oil-free bushing 201 and the bushing mounting shoulder 202 effectively prevent external impurities from entering.

[0055] Next, align the positioning pin 303 at the bottom of the support base 301 with the positioning groove 3031 on the inner wall of the mounting groove 302 on the mounting base 1, so that the support base 301 is accurately placed into the mounting groove 302, ensuring that the support shaft hole 3011 on the support base 301 is coaxial with the shaft hole of the oil-free bushing 201. Finally, fix the positioning pin 303 with the mounting bolt 3032 at the bottom of the mounting base 1, thereby completing the installation of the support base 301.

[0056] During operation, the shaft passes through the shaft holes of the oil-free bushing 201 and the support 301. The self-lubricating properties of the oil-free bushing 201 reduce the frictional resistance between the shaft and the bushing, while avoiding contamination problems caused by lubricating oil. The sealing ring 204 remains sealed at all times, preventing impurities from entering. The coaxial design of the support 301 and the oil-free bushing 201 ensures the shaft's operational accuracy. The entire shaft support structure is stable and reliable, meeting the usage requirements under different working conditions.
