[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] The present utility model has the following beneficial effects:
[0014] 1. When the impact stress of the mechanical equipment is concentrated on the central support, the central support unloads and buffers the stress through the first central buffer assembly and the second central buffer assembly. Then, the central support transfers the stress to the side support and partially unloads and buffers the stress through the leaf spring. And the side support unloads and buffers the transferred stress through the side buffer assembly. This device improves the priority of buffering the central part of the mechanical equipment, reduces the stress concentration on the central part, helps to maintain the overall stability of the equipment, and the side buffer assembly can be used as secondary protection to further reduce the remaining energy that has not been fully absorbed, improving the running smoothness of the equipment.
[0015] 2. Limiting the mounting base in the bearing seat makes the movement directions of the mechanical equipment consistent, prevents the position deviation during the operation of the mechanical equipment, and increases the running stability of the equipment.
[0016] 3. The combination of each damper and the leaf spring for shock absorption and buffering can provide a wider frequency response range, better adapt to different types of vibrations. At the same time, the damping effect of the damper can quickly attenuate the vibration and reduce aftershocks, while the leaf spring can bear larger static and dynamic loads. The combined action of the two can effectively improve the running smoothness and safety of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Generally, when the impact stress of the mechanical equipment is mainly concentrated on the central support 31, the central support 31 decomposes the acting force on the central support 31 into the vertical direction and the lateral direction.

The acting force on the central support 31 is decomposed into the vertical direction and the lateral direction. The impact force in the vertical direction is unloaded and buffered by the first damper 341 and the first buffer spring 342. The impact force in the lateral direction drives the deflection of the limit post 352 through the transmission shaft 351, and then the impact force is unloaded and buffered by the second damper 353 and the second buffer spring 354. At the same time, the other side support 33 unloads and buffers the transmitted stress through the third damper 361 and the third buffer spring 362.
