Description

Technical Field

[0001] This utility model relates to the technical field of motor vibration damping pads, and in particular to a rubber vibration damping pad for motors. Background Technology

[0002] In the field of motors, flexible connections are generally used to reduce vibrations during motor startup and operation. These flexible connections typically employ vibration damping pads. Vibration damping pads consist of two flat plates and a rubber pad between them. During installation, adhesive is applied to both ends of the rubber pad to bond it to the flat plates, ensuring the pad remains centered. However, the ends of the rubber pad harden under adhesive conditions, affecting its lifespan. Furthermore, under prolonged vibration damping, the rubber pad may still shift, causing uneven stress and skewed deformation, ultimately impacting the vibration damping effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rubber vibration damping pad for motors to solve the problem that the installation of the rubber pad in the motor vibration damping pad may be misaligned, affecting the vibration damping effect.

[0004] Based on the technical problems existing in the background art, this utility model proposes a rubber vibration damping pad for motors, including an upper clamping plate, a lower clamping plate, and a rubber pad clamped between the upper clamping plate and the lower clamping plate. The upper clamping plate and the lower clamping plate are each provided with a mounting groove for engaging the rubber pad on the side facing the rubber pad. The two ends of the rubber pad are respectively engaged and installed in the mounting grooves of the upper clamping plate and the lower clamping plate, and the centers of the upper clamping plate, the rubber pad, and the lower clamping plate are kept on the same axis.

[0005] Preferably, the lower clamping plate is provided with at least two sets of vertical guide rods, which pass through the rubber pad from bottom to top and guide the rubber pad.

[0006] Preferably, the guide rod is located in the mounting groove of the lower clamping plate.

[0007] Preferably, the upper clamping plate is provided with a limiting groove for the corresponding guide rod insertion, and the guide rod protrudes from the top of the rubber pad and is inserted into the limiting groove.

[0008] Preferably, the length of the portion of the guide rod protruding from the rubber pad is less than the depth of the limiting groove.

[0009] Preferably, both the upper and lower clamping plates are provided with connecting ears, and the upper and lower clamping plates are arranged in a cross shape.

[0010] Compared with the prior art, the rubber vibration damping pad for motors proposed in this utility model adopts the above-mentioned technical solution and achieves the following technical effects:

[0011] This invention secures the rubber pad by setting mounting grooves in the upper and lower clamping plates, limiting the rubber pad's displacement and ensuring its position relative to the upper and lower clamping plates. Furthermore, the invention increases the structural strength of the rubber pad by using guide rods, preventing it from tilting, ensuring even force distribution, extending its service life, and improving vibration damping.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] Example

[0018] Please refer to Figures 1-3 This utility model proposes a rubber vibration damping pad for motors, including an upper clamping plate 1, a lower clamping plate 2, and a rubber pad 3 clamped between the upper clamping plate 1 and the lower clamping plate 2. The upper clamping plate 1 and the lower clamping plate 2 each have a mounting groove 4 for engaging the rubber pad 3 on their respective sides facing the rubber pad 3. The two ends of the rubber pad 3 are respectively engaged with the mounting grooves 4 of the upper clamping plate 1 and the lower clamping plate 2, thus preventing the rubber pad 3 from shifting relative to the upper clamping plate 1 or the lower clamping plate 2. The upper clamping plate 1, the rubber pad 3, and the lower clamping plate 2 each have a through hole at their center. When the rubber pad 3 is installed between the upper clamping plate 1 and the lower clamping plate 2, the centers of the upper clamping plate 1, the rubber pad 3, and the lower clamping plate 2 are on the same axis, ensuring that the three through holes are also on the same axis. The rubber pad 3 is tubular in shape with a vertical axis.

[0019] In specific implementation, refer to Figure 2 , Figure 3The lower clamping plate 2 is provided with at least two sets of vertical guide rods 5. The guide rods 5 pass through the rubber pad 3 from bottom to top and guide the rubber pad 3. When the rubber pad 3 is compressed or rebounds, the rubber pad 3 can slide longitudinally along the guide rods 5 without tilting or collapsing. Furthermore, the rubber pad 3 can be provided with through holes with the same diameter as the guide rods 5 to facilitate the direct installation of the guide rods 5.

[0020] In specific implementation, refer to Figure 2 , Figure 3 The guide rod 5 is located in the mounting groove 4 of the lower clamping plate 2; the guide rod 5 needs to pass through the rubber pad 3, so it needs to be positioned in the mounting groove 4.

[0021] In specific implementation, refer to Figure 2 , Figure 3 The upper clamping plate 1 is provided with a limiting groove 11 for the corresponding guide rod 5 to be inserted. The guide rod 5 protrudes from the top of the rubber pad 3 and is inserted into the limiting groove 11. The limiting groove 11 can limit the installation position of the top of the guide rod 5, and at the same time limit the position between the upper clamping plate 1 and the lower clamping plate 2. The length of the part of the guide rod 5 protruding from the rubber pad 3 is less than the depth of the limiting groove 11. When the rubber pad 3 is compressed, the gap between the upper clamping plate 1 and the lower clamping plate 2 will decrease. Therefore, the top of the guide rod 5 needs to have a certain buffer space from the top of the upper clamping plate 1 to prevent the guide rod 5 from interfering with the installation of the motor components.

[0022] In specific implementation, refer to Figure 2 , Figure 3 Both the upper clamping plate 1 and the lower clamping plate 2 are provided with connecting ears 6, and the upper clamping plate 1 and the lower clamping plate 2 are arranged in a cross shape.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
