Description

Technical Field

[0001] This utility model relates to the field of bearing equipment technology, and in particular to a suspension bearing with good sealing performance. Background Technology

[0002] As a key component of the suspension system in automobiles, construction machinery, and other equipment, the sealing performance of suspension bearings directly affects the reliability and service life of the equipment. With the increasing demands for operational stability and durability in modern industry, suspension bearings must maintain good sealing performance under complex and changing operating conditions to prevent dust, moisture, and other impurities from entering the bearing.

[0003] Traditional suspension bearings often employ a single sealing structure, such as a lip seal. After long-term vibration and wear, the sealing lip is prone to displacement, leading to an increased sealing gap. This allows external impurities to enter the bearing, making it impossible to provide adaptive elastic support to the bearing position and ensure a smaller sealing gap. Furthermore, the structure is relatively cumbersome to install, and the process is quite complex.

[0004] Therefore, it is necessary to provide a suspension bearing with good sealing performance to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a suspension bearing with good sealing performance, which solves the problem of not being able to provide adaptive elastic support for the bearing position and ensure the reduction of the sealing gap.

[0006] To solve the above-mentioned technical problems, this utility model provides a suspension bearing with good sealing performance, comprising: an installation component and a bearing workpiece. The bearing workpiece is installed inside the installation component for positional support. The installation component is symmetrically provided with clamping components on its side end, and fastening components are provided at both ends of the installation component. The clamping components cooperate with the fastening components to facilitate the installation of the installation component. The installation component is provided with an adaptive limiting component for adaptive limiting of the bearing workpiece. Locking support components are provided at both ends of the adaptive limiting component for supporting and limiting the adaptive limiting component.

[0007] Preferably, the mounting assembly includes a mounting frame and a sealing cover plate. The mounting frame has connecting fastening plates fixed at both ends for fastening the mounting frame. The sealing cover plate is installed on the inner wall of the side end of the mounting frame.

[0009] Preferably, the fastening assembly includes a fastening rod, the inner wall of which is threaded with a fastening ring for clamping the assembly, and the inner wall of the fastening rod has a fastening groove for rotating the position of the fastening rod.

[0010] Preferably, the adaptive limiting component includes a supporting annular plate and an adaptive annular plate. Elastic support members are installed between the inner walls of the supporting annular plate and the adaptive annular plate for elastic support of the adaptive annular plate and for adaptive limiting of the bearing workpiece. A sealing gasket layer is installed on the side end of the adaptive annular plate.

[0011] Preferably, the locking support assembly includes a fixed cavity and a locking rod. A sliding frame is installed on the side end of the fixed cavity for supporting the position of the locking rod. A limit sleeve slides on the inner wall of the locking rod. A limit support rod is installed on the side end of the limit sleeve for supporting the position of the adaptive limit assembly. A locking element is installed on the inner wall of the locking rod for locking support of the limit sleeve.

[0012] Compared with related technologies, the suspension bearing with good sealing performance provided by this utility model has the following advantages:

[0013] Beneficial effects:

[0014] This invention provides a suspension bearing with excellent sealing performance. During daily use, to ensure the bearing's position is limited, an adaptive limiting component and a locking support component work together to sense and adjust the bearing's position in real time.

Then, under the inner wall thread connection, the fastening ring 42 on the inner wall can be positioned along the inner wall to facilitate the convenient positioning and fastening of the clamping component 3.
