Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, and more specifically to a bearing seat with shock absorption and noise reduction functions. Background Art

[0002] Traditional bearing seats play an important role in supporting and fixing bearings in mechanical equipment. However, under high-speed operation or heavy-load working conditions, they often generate significant vibrations and noises. These vibrations not only affect the overall performance of the equipment but may also cause damage to other components of the equipment, shortening the service life of the equipment. At the same time, noise pollution is also an issue that cannot be ignored in industrial production, posing a threat to the physical and mental health of operators. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a bearing seat with shock absorption and noise reduction functions, with the aim of achieving a more practical value. Content of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a bearing seat with shock absorption and noise reduction functions to solve the problems described in the above background art.

[0004] The utility model provides the following technical solution: A bearing seat with shock absorption and noise reduction functions, including a bearing seat main body. The bearing seat main body includes a bearing installation part, an installation connection part, and a bearing body. The bearing seat main body also includes a shock absorption mechanism and a noise reduction mechanism. The shock absorption mechanism includes a first connecting plate, a second connecting plate, and at least one shock absorption column. The first connecting plate is connected to the installation connection part on the bearing seat main body. The shock absorption column is connected to the bottom end of the first connecting plate. The second connecting plate is connected to the bottom end of the shock absorption column. The shock absorption column is composed of a shock absorption spring and a damper. The noise reduction mechanism includes a sound insulation box. The sound insulation box covers the outside of the bearing seat main body. The sound insulation box includes a base material layer. There are two layers of sound absorption cotton arranged on the inner side of the base material layer, and two layers of sound insulation layers arranged on the outside of the base material layer. By providing a shock absorption mechanism and a sound insulation mechanism, the shock absorption mechanism can effectively disperse and absorb the vibration energy from the bearing body. Among them, the shock absorption column integrates a shock absorption spring and a damper, and the two work together to achieve double buffering of vibrations. The shock absorption spring can quickly respond and absorb sudden impact energy, while the damper gradually consumes the vibration energy through its viscous or frictional characteristics, reducing the occurrence of resonance phenomena. The sound insulation mechanism covers the outside of the bearing seat main body as a whole, forming a closed sound insulation space, effectively blocking the noise propagation path. The interior of the sound insulation box adopts a multi-layer structure design. There are two layers of sound absorption cotton and two layers of sound insulation layers arranged on the inside and outside of the base material layer respectively. The sound absorption cotton has good sound absorption performance and can absorb and consume noise energy; while the sound insulation layer further blocks the penetration of noise through its high density and high damping characteristics, improving the sound insulation effect.

[0005] Further, the bearing seat body further includes a guiding assembly, which includes vertical mounting plates. The number of the vertical mounting plates is two, and the two vertical mounting plates are respectively mounted on both sides of the second connecting plate. Guide grooves are respectively formed on one side of the vertical mounting plates facing each other, and guide blocks are slidably mounted inside the guide grooves. The guide blocks are all connected to the first connecting plate to provide stable guidance during the shock absorption process.

[0006] Further, a detachable installation method is adopted between the installation connection part and the first connecting plate, which is convenient for maintenance and replacement.

[0007] Further, rubber pads are installed at the joints between the installation connection part and the first connecting plate to reduce connection gaps, enhance sealing performance, and avoid installation looseness and noise transmission.

[0008] Further, the sound insulation layer of the sound insulation box adopts a multi-layer composite structure, including at least one metal sound insulation plate and one polymer damping material layer to further improve the sound insulation effect.

[0009] Further, the shock absorption springs and dampers of the shock absorption columns can be customized according to different working conditions, including spring stiffness and damping coefficient, to meet the shock absorption and noise reduction requirements of specific application scenarios.

[0010] The technical effects and advantages of the present utility model:

By providing a shock absorption mechanism and a sound insulation mechanism, the shock absorption mechanism of the present utility model can effectively disperse and absorb the vibration energy from the bearing body.

The shock absorption springs can quickly respond and absorb sudden impact energy, while the dampers gradually consume the vibration energy through their viscous or frictional characteristics, reducing the occurrence of resonance. The sound insulation mechanism is integrally covered outside the bearing seat body to form a closed sound insulation space, effectively blocking the noise propagation path. The interior of the sound insulation box adopts a multi-layer structure design, with two layers of sound absorption cotton and two layers of sound insulation layers respectively arranged inside and outside the base material layer.
