Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, specifically to a vibration-damping bearing housing assembly. Background Technology

[0002] In modern industrial production, bearing housings inevitably vibrate, affecting the performance and service life of mechanical equipment.

[0003] The main reason is that when the bearing rotates at high speed, periodic contact stress is generated between the rolling elements and the raceway, leading to elastic deformation and vibration. Since vibration is unavoidable, many methods for vibration reduction have been developed, such as strengthening rigid supports and reinforcing and fixing the bearing and the external frame in the bearing housing. Although this can reduce vibration to a certain extent, long-term use will lead to wear between rigid components, affecting the vibration reduction effect. Therefore, simply strengthening rigid supports is not ideal for vibration reduction. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration-damping bearing housing assembly to solve the problem mentioned in the background art that bearings inevitably vibrate during use, and that simply strengthening rigid support to reduce vibration does not achieve the desired effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping bearing housing assembly, comprising a bearing body, a bearing sleeve, and a bearing housing. The bearing body is fixedly installed in the bearing sleeve, and a mounting plate is fixedly connected to the bottom end of the bearing sleeve. A threaded rod passes through a through hole in the mounting plate and is threadedly connected to a threaded groove. An insert plate is fixedly connected to the bottom end of the mounting plate, and external damping layers are fixedly connected to both sides of the insert plate. The insert plate is inserted into a mounting slot inside the bearing housing, and partition plates are provided on both sides of the mounting slot. Both ends of the partition plates are fixedly connected to the side frames of the partition plates and the bearing housing. An internal damping layer is fixedly connected to the side of the partition plates near the mounting slot.

[0006] Preferably, the built-in damping layer is embedded in the partition plate, and the built-in damping layer is flush with the partition plate at its edge.

[0007] Preferably, the external damping layer is embedded in the insert plate, and the outer surface of the external damping layer is flush with the outer surface of the insert plate.

[0008] Preferably, both the external damping layer and the internal damping layer are made of butyl rubber, and the external damping layer and the internal damping layer are bonded together.

[0009] Preferably, the top of the bearing housing is provided with a mating groove, the size of which is the same as that of the mounting plate, and a rubber pad is fixedly connected to the contact surface between the mounting plate and the mating groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model discloses a vibration-damping bearing housing assembly. Through a structural design in which multiple external damping layers and internal damping layers are bonded together, when the bearing vibrates during operation, energy is sequentially transferred to the external damping layer and the internal damping layer. Through the internal friction loss between the external damping layer and the internal damping layer, the vibration energy is effectively converted into heat energy, thereby enhancing the vibration reduction effect and reducing the noise generated during vibration.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4A vibration damping bearing housing assembly includes a bearing body 1, a bearing sleeve 2, and a bearing housing 3. The bearing body 1 is fixedly installed in the bearing sleeve 2. A mounting plate 21 is fixedly connected to the bottom end of the bearing sleeve 2. A threaded rod passes through a through hole 24 on the mounting plate 21 and is threadedly connected to a threaded groove 32. An insert plate 22 is fixedly connected to the bottom end of the mounting plate 21. External damping layers 23 are fixedly connected to both sides of the insert plate 22. The insert plate 22 is inserted into a mounting slot 35 inside the bearing housing 3. A partition plate 34 is provided on both sides of the mounting slot 35. Side frame 3 is fixed to both ends of the partition plate 34. The mounting plate 21 is fixedly connected to the bearing housing 3. The partition plate 34 is fixedly connected to the side of the mounting slot 35 with the built-in damping layer 36. When the bearing body 1 vibrates during operation, the mounting plate 21 is fixedly installed in the docking slot 31 to achieve a preliminary rigid vibration reduction effect. At the same time, the bearing body 1 and the bearing sleeve 2 transmit the vibration to the insertion plate 22. The external damping layer 23 on the outside of the insertion plate 22 and the built-in damping layer 36 on the partition plate 34 generate internal friction with each other. The internal friction between the external damping layer 23 and the built-in damping layer 36 converts the vibration energy into heat energy, thereby achieving the vibration reduction effect.

[0019] Furthermore, the built-in damping layer 36 is embedded in the partition plate 34, and the built-in damping layer 36 is flush with the partition plate 34 at its edge.

[0020] Furthermore, the external damping layer 23 is embedded in the insert plate 22, and the outer surface of the external damping layer 23 is flush with the outer surface of the insert plate 22.

[0021] Furthermore, both the external damping layer 23 and the internal damping layer 36 are made of butyl rubber, and the external damping layer 23 and the internal damping layer 36 are bonded together.

[0022] Furthermore, a mating groove 31 is provided on the top of the bearing housing 3. The size of the mating groove 31 is the same as that of the mounting plate 21. A rubber pad is also fixedly connected to the contact surface between the mounting plate 21 and the mating groove 31. When the bearing body 1 vibrates due to operation, the vibration is transmitted to the mounting plate 21 through the bearing sleeve 2. The mounting plate 21 utilizes the properties of the rubber pad material to convert some of the vibration energy into heat energy through internal friction, thereby achieving vibration reduction for the mounting plate 21.

[0023] Working principle: In the vibration damping bearing housing assembly of this utility model, when the bearing body 1 vibrates during operation, the mounting plate 21 is fixedly installed in the docking groove 31 to achieve a preliminary rigid vibration damping effect. At the same time, the bearing body 1 and the bearing sleeve 2 transmit the vibration to the insert plate 22. The external damping layer 23 on the outside of the insert plate 22 and the internal damping layer 36 on the partition plate 34 generate internal friction between each other. The internal friction between the external damping layer 23 and the internal damping layer 36 converts the vibration energy into heat energy, thereby achieving the vibration damping effect.
