[0021] In order to make the technical content, the purposes and effects achieved by the utility model clearer, the following will be described in detail in combination with the embodiments and the drawings.

[0022] Please refer to Figure 1 and Figure 2 A guide wheel 24 waterproof structure, comprising a bearing seat 1 and a wheel shaft 2 connected in rotation;

[0023] The outer end surface of the wheel shaft 2 at least partially abuts the outer end surface of the bearing seat 1, and the outer end surface of the wheel shaft 2 abutting the bearing seat 1 is provided with at least one flange 21, and the flange 21 is provided with a radial first groove 22 facing the wheel shaft 2.

[0024] It can be understood that the outer end surface of the wheel shaft 2 refers to the collection of end surfaces extending out of the bearing seat 1; wherein the outer end surface of the wheel shaft 2 at least partially abutting the outer end surface of the bearing seat 1 can be that the extended part of the bearing seat 1 abuts the outer surface of the bearing seat 1 but the two are not in close contact, avoiding increasing the friction when the wheel shaft 2 rotates, causing the workpiece to wear.

[0025] As can be seen from the above description, by designing the flange 21 on the outer end surface of the wheel shaft 2 and the bearing seat 1, and providing the radial first groove 22 on the flange 21 facing the wheel shaft 2, water can be effectively prevented from entering the contact area between the bearing and the wheel shaft 2. The rotational connection between the wheel shaft 2 and the bearing seat 1 usually works in a humid environment, so water penetration is a common problem. By providing the first groove 22, water can be effectively guided into the groove and discharged, thereby avoiding the direct invasion of water into the bearing, preventing water corrosion and wear of the bearing, and prolonging the service life of the bearing. In addition, the design of the flange 21 and the first groove 22 optimizes the water flow path, which helps to reduce the friction resistance of the bearing, thereby improving the working efficiency of the equipment.

[0026] In some embodiments, a process gap 3 is provided between the outer end surface of the wheel shaft 2 abutting the bearing seat 1, and the flange 21 is located in the process gap 3.

[0027] It can be understood that the process gap is the gap between the wheel shaft 2 and the bearing seat 1 to ensure that they do not interfere with each other during rotation, but this gap is easy to be entered by the cooling liquid. In order to solve this problem, the flange is arranged in the process gap, which can provide space for liquid discharge and reduce the possibility of liquid accumulation during rotation. The design of the flange in the process gap 3 allows the liquid to be smoothly discharged when the wheel shaft rotates, avoiding the liquid to be retained in this area, thereby preventing the liquid from causing long-term soaking and corrosion to the process gap between the wheel shaft 2 and the bearing seat 1.

[0028] Specifically, the outer end surface of the bearing seat 1 abutting the wheel shaft 2 is further provided with a second groove 11, and the second groove 11 is located between the flange 21 and the axis of the wheel shaft 2.

[0029] The bearing seat 1 is provided with an air nozzle 12, and the air nozzle 12 communicates with the second groove 11.

[0030] As can be seen from the above description, the design of the air nozzle 12 and the communication with the second groove 11 introduces the air flow injection mechanism into the waterproof structure, further enhancing the waterproof performance. By injecting air flow into the second groove 11, the water that has flowed in can be effectively blown away from the contact area, thereby preventing water accumulation and entering the bearing interior. At the same time, the second groove 11 is located between the wheel shaft 2 shaft center and the bearing seat 1, and the accumulated liquid in the second groove 11 and the first groove 22 is brought out at the same time when air blowing, this design through the dynamic effect of high pressure air flow, not only strengthens the effect of liquid removal, but also avoids the water staying around the bearing for a long time, prevents corrosion and wear. The introduction of air flow makes the equipment more stable when running in a humid environment, reduces the occurrence of mechanical failure, and prolongs the service life of the equipment.

[0031] Further, the air nozzle 12 is used to inject air flow into the second groove 11 to discharge the liquid flowing into the process gap 3. The design of injecting air flow into the second groove 11 to discharge the liquid flowing into the process gap 3 further improves the effect of the waterproof structure. In the traditional waterproof measures, it may not be able to effectively remove the water that stays in the contact area, and by injecting air flow, the water flow can be quickly taken away by the dynamic pressure of the gas, preventing corrosion and wear of the bearing and the wheel shaft 2. The use of air flow reduces the influence of external liquid, improves the stability and reliability of the equipment, especially in high humidity environment or liquid working conditions, which can ensure the equipment to run more efficiently.

[0032] In addition, the process gap 3 is at least partially located in the slot of the first groove 22.

[0033] As can be seen from the above description, the design of the slot of the first groove 22 at least partially towards the process gap 3 allows the water flow to smoothly enter the groove and be quickly discharged. This design can effectively guide the movement direction of the water flow, reduce water retention and accumulation, and avoid water staying in the contact area between the wheel shaft 2 and the bearing seat 1. By utilizing centrifugal force and bearing rotation, the water flow can be quickly discharged, thereby effectively preventing water from entering the bearing interior and preventing corrosion and wear problems caused by water. This design not only improves the waterproof effect, but also optimizes the overall performance of the equipment, ensuring its stability during long-term use.

[0034] In some embodiments, the part of the outer circumference of the wheel shaft 2 extending out of the bearing seat 1 is provided with a third groove 23, and the slot of the third groove 23 is towards the radial direction of the wheel shaft 2.

[0035] As can be seen from the above description, the wheel shaft 2 is provided with a third groove 23 and is located at the part of the wheel shaft 2 extending to the bearing seat 1, and the slot of the third groove 23 is directed towards the radial direction of the wheel shaft 2, which helps to further enhance the water discharge and protection effect. This design can provide an additional drainage channel when water flows into the bearing area, so that the water flow can be more effectively guided to the outside for discharge, thereby reducing the water accumulation in the bearing. This multi-protection design improves the overall waterproof capability of the structure, especially in high-pressure water or humid environment, which can better prevent liquid penetration and improve the reliability and durability of the equipment.

[0036] In some embodiments, the wheel shaft 2 is provided with a guide wheel 24 connected to the outer end surface of the wheel shaft 2, and the outer circumference of the guide wheel 24 is provided with a fourth groove 25.

[0037] As can be seen from the above description, the wheel shaft 2 is provided with a guide wheel 24 connected to the outer end surface, and the outer circumference of the guide wheel 24 is provided with a fourth groove 25, which can further enhance the waterproof function of the structure. At the same time, the fourth groove 25 can be used to accommodate and position the external wire, such as the wire saw of the cutting wheel system.

[0038] In some embodiments, a sealing member is provided between the wheel shaft 2 and the bearing seat 1 to prevent liquid from entering the area of rotational contact between the wheel shaft 2 and the bearing seat 1.

[0039] As can be seen from the above description, the sealing member is provided between the wheel shaft 2 and the bearing seat 1, which can effectively prevent liquid from entering the rotational contact area of the wheel shaft 2 and the bearing seat 1. The sealing member forms a waterproof barrier through close contact, preventing liquid penetration, especially in humid environments or under high-pressure water, which can effectively isolate the contact between external liquid and internal bearing, preventing corrosive liquid from entering the bearing interior and preventing bearing damage. At the same time, the sealing member can also reduce the leakage of lubricating oil, thereby improving the efficiency of the equipment, reducing maintenance costs, and ensuring the stability of the equipment during long-term use.

[0040] In some embodiments, the flange 21 is an annular flange 21, and the outer end surface of the bearing seat 1 is provided with a receiving groove 13 matching the position of the flange 21.

[0041] As can be seen from the above description, the annular flange 21 and the bearing seat 1 are provided with a receiving groove 13 matching the position of the flange 21, which can make the flange 21 and the bearing seat 1 cooperate, prolong the liquid flow path, and thereby enhance the waterproof effect. This design ensures the perfect fit between the flange 21 and the bearing seat 1, preventing water from penetrating into the bearing due to excessive distance between them. At the same time, the design of the receiving groove 13 can help optimize the water flow guide path, so that the water can be more smoothly discharged, avoiding the damage caused by water accumulation. This structure not only improves the waterproof performance, but also increases the reliability and sealing of the assembly, ensuring the long-term stable operation of the equipment in various complex environments.

[0042] In summary, the utility model provides guide wheel waterproof structure, first, through the flange of wheel shaft and bearing seat outer end face design, and set up the radial first recess groove towards the wheel shaft on the flash, can effectively guide water flow to recess and remove, avoid moisture directly into the bearing interior, thereby prevent water from corrosion and wear of bearing.

[0043] At the same time, process gap and second recess are set in the design, providing additional water flow channel, effectively reducing the accumulation of moisture in the contact area. Combined with the design of air nozzle jet airflow, moisture can be quickly blown away from the contact area, preventing moisture from staying in the bearing, reducing the risk of corrosion, and improving equipment operation efficiency.

[0044] Secondly, a third recess is designed on the outer extension part of the wheel shaft, further optimizing the water flow discharge path and reducing the possibility of water flow entering the bearing interior, forming a multiple protection system. This design is particularly effective in high humidity environments, ensuring that the equipment is more reliable and durable, reducing equipment failure and downtime caused by moisture intrusion.

[0045] In addition, since the oil gas lubrication method is not used, the loss of lubricating oil is reduced, and the pollution of the working environment caused by the outflow of lubricating oil is avoided. At the same time, the consumption of lubricating oil is reduced, the operation cost of the equipment is reduced, and it is more environmentally friendly and economical.

[0046] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent transformation or direct or indirect application in related technical fields using the contents of the utility model specification and drawings is also included in the patent protection range of the utility model.
