Based on the modification of the end tooth processing equipment of the bevel gear planer, due to the difference in the tooth surface structure between the bevel gear and the face gear, it is necessary to make some corresponding changes to the equipment when machining the face gear with the bevel gear planer. Instructions can be made on the basis of the Y2360 bevel gear planer. The development of several movements of the original bevel gear planer is no longer required. This only needs to remove the hobbing ratio exchange gear and the swing angle exchange gear in the bevel gear planer, without much modification to the machine tool. Due to the single-tooth cutting process of the face gear, the angle of the tool holder rail to be controlled is changed from the top of the tooth to the bottom of the tooth, that is, the angle between the two tool holders in the stepwise feeding process along the tooth depth direction It must be changed from 0b to (360b/zE), and the angle of the two tool holder rails in the process of machining the bevel gear is not changed after the workpiece number is adjusted, so the feed motion and the tool holder are required. An inner linkage transmission device is arranged between the guide rails to rotate the tool holder rail with the feeding motion, thereby changing the angle.
In order to simplify the structure of the machine tool, left-handed/right-handed nuts 1, 2 are respectively arranged on the tool holder rail, and two nuts are coupled with the opposite ends of the screw, and the lower end of the screw is connected with the stepping motor. When the screw is rotated, the two tool holders can be rotated to increase or decrease the angle. The modified bevel gear planer is shown in Figure 7. The table is measured by the grating and other devices during the feed, and the data is transmitted to the single-chip microcomputer. Then the single-chip computer controls the stepping motor to rotate, thereby driving the screw to rotate. The two tool holders are rotated at an appropriate angle to achieve the linkage between the feed motion and the tool holder rail.
According to the processing principle of the bevel gear planer, it is feasible to realize the face gear tooth surface machining. It only needs to cooperate with the linear feed of the face gear (workpiece) (can be controlled by computer), and the end tooth can be processed. surface. The design of the Y2360 bevel gear planer designed in this paper is simple and easy to implement, and has good implementability. If we further discuss the control of the stepper motor in the single-chip microcomputer, we can also complete the processing of the top part and the bottom part of the tooth bottom, and also expand the bevel gear processing function to make it more suitable for flexible production.
Iron Based Alloy Powder
Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.
The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
