Description

Technical Field

[0001] This utility model relates to the field of motor sealing technology, specifically a sealing assembly for a single-axis vibration motor. Background Technology

[0002] In modern mechanical equipment, single-axis vibratory motors are widely used as a crucial drive source in industries such as mining, chemical, and construction, playing a vital role, especially in equipment like vibrating screens and vibrating feeders. Because these devices typically operate in environments with high-intensity vibration and harsh conditions, the stability and durability of the sealing system directly affect the equipment's operating efficiency and lifespan. Therefore, effectively preventing liquid leakage and maintaining good sealing performance has become a key technical issue in vibratory motor design.

[0003] Most existing single-axis vibration motor sealing assemblies adopt traditional mechanical seal structures. However, this structure is easily affected by vibration during long-term operation, leading to reduced sealing performance and even leakage. In addition, the durability and vibration absorption performance of the sealing materials in the current technology are also somewhat insufficient. Especially in high-intensity vibration environments, the working stability of the sealing assembly is poor, which can easily lead to equipment failure.

[0004] In view of this, we have studied and improved the existing problems to provide a single-axis vibration motor sealing assembly to solve the current problems. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0006] The present invention adopts the following technical solution:

[0007] Fitting of the pressure ring disc and the flange seat: The single-axis vibration motor sealing assembly of this utility model includes a pressure ring disc, a flange seat, and a sleeve tube, wherein the pressure ring disc and the flange seat are rotated and fitted onto the surface of the sleeve tube, and are connected by a sealing structure.

[0008] The function of the floating disc: The floating disc, which slides against the surface of the pressure ring disc at one end of the sleeve tube, provides additional axial guidance and ensures stable sealing performance.

[0009] The plug hole design for adjusting the sealing effect: The pressure ring plate and the flange seat are respectively provided with a first plug hole and a second plug hole, and the oil pressure is adjusted by the first and second adjusting plugs to further improve the sealing effect.

[0010] Application of flexible positioning ring: The piston ring is slidably sleeved on the inner side of the wing ring, and a deformation sleeve is provided on one side of the piston ring. Its end is fixedly sleeved on the outer circumference of the sleeve shaft tube, providing a flexible limiting function, thereby reducing the impact of vibration on the sealing assembly.

[0011] Hydraulic adjustment and energy absorption design: This utility model is also designed to increase the radial contact pressure between the deformation sleeve and the packing through hydraulic adjustment, further enhancing the sealing ability. At the same time, the flexibility of the piston ring and deformation sleeve materials helps to absorb vibration and reduce the negative impact of vibration on the sealing effect.

[0012] Polytetrafluoroethylene (PTFE) shaft seal ring: The shaft seal ring is fitted inside the pressure ring disc and is made of PTFE, which has excellent wear resistance and corrosion resistance, effectively ensuring the long-term stable operation of the sealing assembly.

[0013] Through the above design, this utility model can provide a stable sealing effect in high-intensity vibration working environments, and the sealing pressure can be adjusted by the hydraulic system to ensure the normal operation of the vibration motor, reduce damage to the equipment, and extend its service life.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, through the hydraulic adjustment system between the pressure ring disc and the flange seat, as well as the flexible limiting effect of the piston ring and the deformation sleeve, stable axial and radial sealing can be achieved under high-intensity vibration environment, preventing oil leakage and the entry of external contaminants, thereby significantly improving sealing performance.

[0016] 2. In this utility model, the first adjusting plug and the second adjusting plug can adjust the oil pressure, further optimize the sealing effect, flexibly adjust the damping state under different working conditions, and ensure that the sealing component always maintains the best working state.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following is in conjunction with the appendix Figures 1-4 This invention describes a single-axis vibration motor sealing assembly provided by some embodiments of the present invention. Example 1

[0026] like Figure 1 As shown, the pressure ring disc 1 is rotatably connected to the sleeve tube 3 via the flange seat 2, forming an adjustable sealing structure between the pressure ring disc 1 and the flange seat 2. A floating disc 31 is rotatably fitted onto one end of the sleeve tube 3, slidingly abutting against the surface of the pressure ring disc 1, and axial movement and sliding guidance are achieved through the floating disc 31. A wing ring 11 is provided on one side of the pressure ring disc 1, movably fitted inside the flange seat 2. This design enhances the sealing effect, and the deformation of the wing ring 11 provides flexible positioning between the pressure ring disc 1 and the flange seat 2.

[0027] By creating a first plug hole 4 and a second plug hole 5 on the surfaces of the pressure ring disc 1 and the flange ring seat 2, and threading a first adjusting plug 41 and a second adjusting plug 51 into them respectively, the pressure and flow of the internal oil can be precisely adjusted, thereby achieving dynamic adjustment of the sealing effect. A piston rod 6 is rotatably mounted at the bottom end of the first adjusting plug 41 and the second adjusting plug 51. These piston rods, through hydraulic action, push the piston ring 8 and the deformation sleeve 81 to deform or displace accordingly, further improving the sealing performance and strengthening the radial contact pressure between the sleeve tube 3 and the pressure ring disc 1.

[0028] An integral rubber component is used between the piston ring 8 and the deformation sleeve 81 to ensure that it can absorb vibration and provide radial flexible limiting during operation. One end of the deformation sleeve 81 is provided with a flexible positioning ring 82 that is fixedly sleeved on the outer circumference of the sleeve shaft tube 3. Through this structural design, the impact of vibration generated during the operation of the vibration motor on the sealing assembly can be effectively reduced, and the stability and service life of the sealing assembly can be improved. Example 2

[0029] In another embodiment, considering different working environments, both ends of the sleeve tube 3 are provided with raised steps, which abut against the surfaces of the pressure ring disc 1 and the floating disc 31, respectively. This design makes the sliding contact between the pressure ring disc 1, the flange ring seat 2, and the floating disc 31 more stable, and increases the rigidity of the sealing assembly, preventing displacement or damage under high vibration conditions.

[0030] Furthermore, damping fluid is injected into the inner sides of the pressure ring disc 1 and the flange ring seat 2, and the inner cavities of the pressure ring disc 1 and the flange ring seat 2 are connected through the first plug hole 4 and the second plug hole 5. This design can provide effective hydraulic support during operation, helping to improve the durability and vibration resistance of the sealing assembly, and ensuring the stability of the seal during long-term high-intensity operation. Example 3

[0031] To improve the sealing effect, the shaft seal ring 7 is made of polytetrafluoroethylene and is fitted inside the pressure ring disc 1 to achieve radial sealing between the pressure ring disc 1 and the sleeve tube 3. In practical applications, the shaft seal ring 7 works in conjunction with the piston ring 8 to further enhance the sealing performance, prevent external contaminants from entering the sealing area, and maintain the tightness of the oil, ensuring the normal operation of the equipment.

[0032] Working principle and usage process of this utility model:

[0033] Under normal operating conditions, the shaft sealing ring 7 and piston ring 8 work together to achieve radial sealing between the surface of the sleeve tube 3 and the pressure ring disc 1 and flange ring seat 2. At the same time, the raised steps at both ends of the sleeve tube 3 achieve abutment and locking between the pressure ring disc 1, flange ring seat 2 and floating disc 31.

[0034] After adding oil to the inside of the pressure ring disc 1 and the flange ring seat 2, the pressure on the surface of the shaft sealing ring 7, piston ring 8 and deformation sleeve 81 can be further increased, the joint strength can be improved, and the shaft sealing ring 7 can be pushed to move axially, so that its outer circumference is tightened with the inner side of the pressure ring disc 1, thereby achieving radial sealing between the pressure ring disc 1 and the sleeve tube 3.

[0035] When the vibratory motor is running, the main shaft vibrates inside the sleeve tube 3, and the vibration energy is absorbed by the flexible shaft sealing ring 7 and piston ring 8. At the same time, the floating disk 31 forms a sliding guide on one side of the pressure ring disk 1 to further absorb the vibration energy, and the movement of the damping fluid inside the pressure ring disk 1 and flange ring seat 2 further absorbs the vibration impact.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
