Description

Technical Field

[0001] This utility model relates to the field of quenching processing technology, specifically a gear quenching tracking device. Background Technology

[0002] The quality of gear surface hardening is one of the important factors affecting the service life of large turntable bearings, wind turbine yaw bearings, and pitch bearings. The ease of installation, durability, tracking accuracy, and materials of the gear hardening tracking device affect the production efficiency of gear hardening and the uniformity of the hardened layer on the left and right tooth surfaces of the gear.

[0003] The existing tracking device is cylindrical. Although it is relatively easy to manufacture, it requires machining bars of different diameters for gears with different modules. The cylindrical tracking device has a large contact area with the gear surface, which easily causes tooth surface wear and affects the quality of tooth surface quenching. In addition, a single bar can only cover the quenching of gears with similar modules, such as M10, M12, and M14, but cannot completely cover the quenching of all gears from M8 to M24. When a changeover is required, if the gear modules differ significantly, a different specification of cylindrical tracking device must be replaced, increasing changeover time and affecting production efficiency.

[0024] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] See Figure 1 The diagram shows a structural schematic of a gear quenching tracking device according to an embodiment of the present invention, which includes a fixing member 100, a connecting rod 200, and a tracking ball head 300; the fixing member 100 is disposed on the moving table of the quenching equipment; the connecting rod 200 is connected to the fixing member 100, such as... Figure 1 As shown, in this embodiment, the connecting rod 200 is detachably fixed to the fixing member 100 by the first connecting bolt 210. The fixing method is not limited in specific configurations.

[0026] See also Figure 1 and Figure 2 The tracking ball head 300 is detachably mounted on the end of the connecting rod 200. The two sides of the tracking ball head 300 are respectively used to mate with the two sides of the tooth surfaces of the recess 11 between two adjacent teeth of the gear 10. The specific connection method of the tracking ball head 300 at the end of the connecting rod 200 in this invention is not limited, but the two must be detachably connected to ensure left-right symmetry accuracy, which directly affects the quenching depth of the left and right tooth surfaces. As an example, in this embodiment, a through hole 220 is provided on the central axis of the connecting rod 200, and a connecting hole 321 is provided at the connection position of the tracking ball head 300. A second connecting bolt 230 passes through the through hole and is threaded into the connecting hole 321.

[0027] It should be noted that the same tracking ball head 300 can be used for quenching gears of various specifications. Based on this, in this embodiment, a second connecting bolt 230 is used to connect the tracking ball head 300, facilitating the replacement of tracking ball heads 300 of different specifications to accommodate more gear sizes. When the tracking ball head 300 wears or encounters other problems, it is easy to disassemble and replace without needing to replace the fixing part 100 and connecting rod 200, thus reducing costs. Specifically, this device is made of 1Cr18Ni9 material, which can effectively resist high temperatures and prevent high-temperature deformation during quenching.

[0028] The aforementioned gear quenching tracking device is equipped with a tracking ball head 300. The tracking ball head 300 makes point contact with the tooth surface in both the X-axis and Y-axis directions. This effectively reduces friction between the tracking ball head 300 and the tooth surface, improving product quality. Furthermore, the tracking ball head 300 can adapt to quenching various gear specifications, making it widely applicable.

[0029] See Figure 3 In one embodiment, the tracking ball head 300 includes a spherical convex surface 310 that mates with the recess 11 between two adjacent teeth and a connecting plane 320 with a connecting hole 321 in the center.

[0030] See also Figure 4 Furthermore, in one embodiment, a cross-shaped positioning recess 322 is provided on the connecting plane 320, and a connecting hole 321 is formed at the center of the cross-shaped positioning recess 322. In one embodiment, the cross-shaped positioning recess 322 is recessed 3mm relative to the connecting plane 320.

[0031] The aforementioned gear quenching tracking device has a cross-shaped positioning recess 322 on the connecting plane 320. This recess can be used to position the machining location. During use, a line can be selected within the cross-shaped positioning recess 322 as the positioning line. The points on the corresponding spherical convex surfaces 310 at both ends of the selected positioning line contact the tooth surface. After using one end for a period of time, the tracking ball head 300 can be rotated to use another line as the positioning line, and the points on the corresponding spherical convex surfaces 310 at both ends of the second selected positioning line contact the tooth surface. With this configuration, the cross-shaped positioning recess 322 can serve as a positioning reference, and the direction of the tracking ball head 300 can be adjusted during machining. The tracking ball head 300 can be reused, thus saving costs.

[0032] In one embodiment, the tracking ball head 300 has a spherical structure that is more than half the size of a ball after being cut by a plane.

[0033] In one embodiment, the maximum diameter of the tracking ball head 300 perpendicular to the axial direction of the connecting hole 321 is 22mm. In this embodiment, the size of the tracking ball head 300 can cover various specifications of gear quenching, such as M8, M10, M12, M14, and M22 gears, with a wide range of applications, reducing changeover time and improving production efficiency.

[0034] See Figure 4 In one embodiment, the connecting hole 321 is an M6 threaded hole.

[0035] In one embodiment, the fixture 100 is equipped with a sensor 110 located below the tracking ball head 300.

[0036] During installation, the tracking ball head 300 is fixed to the connecting rod 200 using the second connecting bolt 230. The connecting rod 200 is connected to the fixing member 100 using the first connecting bolt 210, and the fixing member 100 is installed on the moving platform of the quenching equipment. The tracking ball head 300 is manufactured strictly according to the drawing requirements, ensuring that the positioning accuracy is within 0.1mm, based on the outer diameter φ22 of the cross-shaped positioning recess 322 and the centrally opened connecting hole 321, to guarantee its centered position and thus ensure uniform hardening of the left and right tooth surfaces.

[0037] See also Figure 1 and Figure 2 During quenching, the gear quenching proceeds from bottom to top. First, the tracking ball head 300 contacts the tooth surface. After contact, the tracking ball head 300 feeds back coordinate information to the system. The system then adjusts the coordinate position of the sensor 110 in real time based on this information to ensure the uniformity of the hardened layer on the left and right tooth surfaces. The tracking ball head 300 is positioned directly above the sensor 110. The operating temperature during quenching can reach 900-950℃. This device is made of 1Cr18Ni9 material, which can effectively resist high temperatures.

[0038] It should be noted that in the prior art, the cylindrical tracking device is too long in the axial direction, which is affected by the tooth profile at various positions in the axial direction of the gear. This makes it impossible to accurately reflect the shape of the gear corresponding to the sensor 110, thus affecting the inconsistent hardening layer depth of the left and right tooth surfaces of the gear. In this embodiment, the tracking ball head 300 does not have this problem. In addition, the high temperature during the quenching process of the cylindrical tracking device has a significant thermal impact on the tracking device, which can easily cause deformation such as bending. In this embodiment, the tracking ball head 300 is less affected by heat, and the possibility of deformation is also reduced.
