Description

Technical Field

[0001] The present application relates to the field of gear processing, and in particular to a new type of wear-resistant gear that is easy to detect. Background Art

[0002] Gear systems play a crucial role in industrial applications, with their performance directly impacting the stability and efficiency of mechanical equipment. Over extended periods of operation, gears often experience wear and overheating, which can reduce gear fatigue resistance, shorten their service life, and even lead to equipment failure. Therefore, improving gear wear resistance and temperature monitoring capabilities has become a pressing technical challenge in the industrial sector.

[0003] Existing technologies typically rely on the periodic addition of lubricating oil or grease for gear lubrication. This method is not only inefficient but also makes it difficult to ensure even distribution of the lubricant to each tooth. Furthermore, gear overheating is typically monitored using indirect temperature sensors, which often fail to accurately measure the actual operating temperature of the gear teeth, making it difficult to effectively prevent overheating in a timely manner. Utility Model Content

[0004] The purpose of this application is to provide a new type of gear that is easy to detect and resist wear, which is used to detect gear overheating and improve the wear resistance of gears, thereby improving their fatigue resistance and service life. To achieve the above purpose, this application provides the following technical solutions: A new type of gear that is easy to detect and resist wear, including:

[0006] An oil storage ring is sleeved on the positioning shaft. The oil storage ring is an annular structure with an array of oil outlet channels around it. The oil outlet channels correspond to the tooth grooves one by one. The lower end of the tooth groove is provided with an oil outlet, and the oil outlet is connected to the tooth groove;

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on this application.

[0022] Furthermore, it should be understood that for ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0023] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0024] In order to solve the technical problems in the background technology, such as Figure 1-2 As shown, the present application provides a technical solution: a new type of gear that is easy to detect wear-resistant gears, which has the following characteristics:

[0025] The gear body 1 includes a positioning shaft 2, a positioning hole 3 and teeth 4. The positioning hole 3 is designed as a through structure and is coaxially arranged with the positioning shaft 2 to ensure the stability and concentricity of the gear body 1. The teeth 4 are connected to the periphery of the positioning shaft 2 in a circumferential array, and their axial diameter along the positioning shaft 2 gradually decreases to form a special tooth structure. Specifically, the teeth 4 are distributed on the surface of a cone, and their tooth shape gradually decreases from the large end to the small end. Tooth grooves 5 are formed between adjacent teeth 4. These tooth grooves 5 not only provide structural support for the gear, but are also used to distribute lubricating oil. This design has high load-bearing capacity, high transmission efficiency, stable transmission ratio, and is conducive to reducing wear and increasing the service life of the gear. The oil storage ring 6 is sleeved on the positioning shaft 2 and has an annular structure. The inner side of the oil storage ring 6 is tightly fitted with the outer side of the positioning shaft 2 to prevent the oil storage ring 6 from slipping when the gear body 1 rotates. The oil reservoir ring 6 is surrounded by an array of oil outlet channels 7, each corresponding to the tooth grooves 5 between the teeth 4. Lubricating oil in the oil reservoir ring 6 is delivered directly to each tooth groove 5 through the oil outlet channels 7, ensuring effective delivery of lubricant to every working surface of the gear. An oil outlet 8 is designed at the lower end of each tooth groove 5, connected to the corresponding tooth groove 5, ensuring adequate lubrication of the gear 4. Lubricating oil first enters the tooth groove 5 through the oil outlet channel 7 and is then transported to the gear 4 through meshing rotation and the centrifugal force of rotation. A temperature measuring patch 9 is affixed to the upper end of each gear 4. The back of the temperature measuring patch 9 is provided with a self-adhesive sticker, allowing it to be easily fixed to the gear 4 to assess the gear's operating condition and wear. The temperature measuring patch 9 is a color-changing temperature patch that monitors and records the temperature of the gear 4 in real time. The temperature measuring patch 9 features unique color-changing temperature indication, a striking display, and temperature recording capabilities, and comes with a self-adhesive sticker for easy attachment. Once the temperature of the monitored area reaches or exceeds the rated temperature of the temperature measuring strip 9, the strip 9 rapidly changes color. For example, when the temperature exceeds the rated temperature, the strip 9 changes color from white to black, creating a striking color change. This makes it easy for personnel to detect elevated temperatures in the monitored area during daytime or nighttime inspections, thereby identifying potential faults and preventing accidents. If the temperature measuring strip 9 changes color due to excessive temperature in the monitored area, it will not return to its original white color after cooling, and will remain in a recording state.

[0026] Furthermore, a guide groove 10 is added to further optimize the flow and distribution of lubricating oil. Guide groove 10 is provided on the side of the tooth groove 5 that connects to the oil outlet 8. Guide groove 10 is designed to guide the lubricating oil in the oil reservoir ring 6 from the oil outlet 8 to the working surface more efficiently, ensuring that the lubricating oil is evenly distributed to each tooth 4. The lubricating oil enters the tooth groove 5 through guide groove 10, forming an oil film within the tooth groove 5, which provides lubrication.

[0027] It should be noted that the guide groove 10 is designed as a wedge-shaped groove. This structure helps to effectively push the lubricating oil from the oil reservoir ring 6 to the oil outlet 8 during gear operation using centrifugal force, evenly distributing it to the teeth 4 and preventing irregular spillage of the lubricating oil. The size of the guide groove 10 gradually narrows from the side closest to the oil outlet 8 to the side away from the oil outlet 8. This variable design allows the lubricating oil to gradually slow down during flow, allowing it to enter the working surface more effectively and gradually, thus promoting a concentrated flow of lubricating oil and ensuring a moderate flow rate at the oil outlet 8.

[0028] Furthermore, the length of the guide groove 10 is designed to be less than 1 / 5 of the length of the tooth groove 5. This design principle is based on considerations of lubricating oil flow dynamics to ensure that lubricating oil can effectively flow from the oil storage ring 6 to the oil outlet 8 while preventing excessive lubricating oil from accumulating in the tooth groove 5.

[0029] It should be noted that the teeth 4 are designed as curved teeth. This design provides smoother meshing and reduces impact and noise during gear operation. The curvature of the curved teeth 4 can be optimized based on the expected load and speed of the gear. The tooth grooves 5 extend along the curved sides of the curved teeth 4. This design allows the lubricant to form a continuous oil film across the entire surface of the teeth 4, thereby reducing wear and increasing the service life of the gear.

[0030] Furthermore, the design of the spur gear 11 is added to provide additional transmission functions and improve the stability of the gear. The spur gear 11 is designed to be coaxial with the positioning shaft 2 and is arranged on the periphery of the positioning shaft 2. The introduction of the spur gear 11 can provide additional transmission ratio options, so that the gear system can adapt to more application scenarios. The cooperation between the spur gear 11 and the positioning shaft 2 can be achieved in a variety of ways. For example, the spur gear 11 can be formed directly on the positioning shaft 2 through a key connection, a spline connection, or by forming the spur gear 11 directly on the positioning shaft 2. This cooperation ensures the stability and synchronization of the spur gear 11 during operation. The coordinated work of the spur gear 11 and the arc-shaped teeth 4 can provide a smooth transmission effect. The spur gear 11 can mesh with another gear, and the arc-shaped teeth 4 provide an additional transmission surface, thereby dispersing the load and reducing wear.

[0031] It should be noted that an oil filling port 12 is provided on the upper portion of the oil reservoir ring 6 for adding lubricating oil to the oil reservoir ring 6. The design of the oil filling port 12 facilitates the addition of lubricating oil and also facilitates oil level monitoring. The oil filling port 12 can be equipped with a sealing cap to prevent lubricating oil leakage and contamination. The sealing cap can be designed with a threaded connection or a rubber extrusion connection for quick opening and closing during maintenance.

[0032] It should be noted that the oil reservoir ring 6 is designed to be removable, allowing it to be removed from the gear body 1 for maintenance or lubricant replacement when needed. This design improves the maintainability of the gear system, making regular inspection and maintenance more convenient. The inner diameter of the oil reservoir ring 6 is designed to be larger than the outer diameter of the spur gear 11, ensuring that the oil reservoir ring 6 can be directly removed from the spur gear 11.

[0033] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
