Description

Technical Field

[0001] This utility model belongs to the technical field of elastic damping vibration reduction and anti-torsion connection parts for textile fan hubs, and more specifically, it relates to an elastic damping vibration reduction and anti-torsion connection part for textile fan hubs. Background Technology

[0002] The impeller hub of the textile fan is the core load-bearing component connecting the impeller and the drive shaft. It is made of lightweight and high-strength cast aluminum alloy (such as ZL114A) or ductile iron (QT500-7), and the surface is coated with polytetrafluoroethylene to resist the moisture and chemical fiber corrosion in textile workshops. Its precision dynamic balance design (ISO 1940G6.3 level) ensures that the vibration speed is ≤2.8mm / s under high-speed operation of 1500~3500rpm, synchronously transmits torque and bears aerodynamic loads, and has a design life of over 100,000 hours. It is specially optimized for high-efficiency scenarios such as vortex spinning machines and chemical fiber exhaust fans.

[0003] When installing the hub of a textile fan, it is necessary to use corresponding connectors to assemble it onto the equipment. When there is oil or dirt between the bolting surfaces of the hub and the main shaft, the coefficient of friction will decrease, causing misalignment and slippage between the hub and the main shaft mating surfaces, resulting in low-frequency abnormal noise. At the same time, the hub of the textile fan is also prone to vibration during use, which can easily lead to wear of the connectors.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an elastic damping vibration reduction and anti-torsion connection for textile fan hubs, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an elastic damping vibration reduction and anti-torsion connecting component for a textile fan hub, which is achieved by the following specific technical means:

[0006] An elastic damping vibration reduction and anti-torsion connector for a textile fan hub includes a connecting column. A structural groove is formed at the top of the connecting column. A rubber pad is provided inside the structural groove. A threaded rod is provided on the side of the rubber pad away from the structural groove. A threaded block is provided on the side of the threaded rod away from the rubber pad. A fixing ring is threadedly connected to the threaded rod through the threaded block. A limit ring is provided on the side of the connecting column away from the fixing ring.

[0007] Furthermore, locking blocks are provided on both sides of the limiting ring.

[0008] Furthermore, the limiting ring is provided with a sponge block near the pair of engaging blocks.

[0009] Furthermore, the connecting column is made of stainless steel.

[0010] Furthermore, the limiting ring is made of aluminum alloy.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, the combined use of rubber pads, threaded rods, threaded blocks, and fixing rings can effectively alleviate the vibration of the entire device, while the combined use of sponge blocks and limiting rings can effectively improve the wear resistance of the entire connector.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides an elastic damping vibration reduction and anti-torsion connector for a textile fan hub, including a connecting column 1, a structural groove 2 at the top of the connecting column 1, a rubber pad 3 inside the structural groove 2, a threaded rod 4 on the side of the rubber pad 3 away from the structural groove 2, a threaded block 5 on the side of the threaded rod 4 away from the rubber pad 3, a fixing collar 6 threadedly connected to the threaded rod 4 through the threaded block 5, and a limit ring 7 on the side of the connecting column 1 away from the fixing collar 6.

[0025] The limiting ring 7 has locking blocks 8 on both sides.

[0026] Among them, the limiting ring 7 is provided with a sponge block 9 near a pair of locking blocks 8, and the sponge block 9 can effectively improve its friction.

[0027] Among them, the connecting column 1 is made of stainless steel, which has strong corrosion resistance and a long service life.

[0028] Among them, the limiting ring 7 is made of aluminum alloy, which is lightweight and has a certain strength.

[0029] The working principle of this embodiment is as follows: When using this utility model, the user places the rubber pad 3 into the structural groove 2 at the top of the connecting column 1, ensuring a tight fit. Then, the threaded rod 4 passes through the rubber pad 3 and is threadedly connected to the fixing ring 6 through the threaded block 5. The fixing ring 6 is tightened to achieve initial fixation. Next, the limiting ring 7 is installed on the side of the connecting column 1 away from the fixing ring 6, ensuring that the locking blocks 8 on both sides are accurately engaged in the corresponding positions. The sponge block 9 near the locking block 8 of the limiting ring 7 increases the connecting friction. During installation, it should be noted that the connecting column 1 is made of stainless steel, which has strong corrosion resistance and does not require frequent maintenance. The limiting ring 7 is made of aluminum alloy, which is lightweight and has a certain strength, avoiding deformation due to excessive force. The overall vibration reduction effect is achieved through the elastic damping effect of the rubber pad 3. The anti-torsional performance and stability of the fan during operation are improved through the coordinated cooperation of various components.
