Embodiment Construction

[0014] like figure 1 and figure 2 As shown, a large involute spur gear repair welding method and its device, using Siemens' S7-200 software and V4.0STEP7-Micro / WIN software, and the CPU224 in the S7-200 series PLC as the control system, To control the repair welding device, the steps of repair welding are as follows:

[0015] a. Place and fix the worn large gear 28 horizontally, then place the repair welding device on the worn large gear 28, and position it through the shaft hole of the worn large gear 28;

[0016] b. After the repair welding device is positioned, the motor 2 on the X-axis in the device drives the X-axis screw 4; the motor 8 on the Y-axis drives the Y-axis screw 23; the motor 22 on the Z-axis drives the Z-axis screw 18, through The common linear motion of the X-axis screw 4, the Y-axis screw 23 and the Z-axis screw 18 positions the welding torch 27 to the worn part of the large gear;

[0017] c. After the welding torch 27 is positioned, the motor 22 on the...

Abstract

The invention discloses a repair welding method and device for large involute spur gears, which can efficiently repair worn large involute spur gears. The repair welding method is as follows: put the repair welding device on the worn large gear, and locate it through the shaft hole of the worn large gear; position the welding torch on the worn part of the large gear; The first layer is repaired, and then the welding torch is used in the same way to complete the repair welding of the next repair layer until the repair welding of a worn large gear is completed. The device includes: X-axis slideway, motor on X-axis, X-axis lead screw, lower straightening roller, upper straightening roller, motor on Y-axis, welding wire wheel, wire feeding motor, welding torch bracket, Z-axis slideway , the motor on the Z axis, the slideway on the Y axis, the welding wire and the welding torch. The invention improves the utilization rate of the gear and reduces the production cost; the structure of the repair welding device is reasonable, and the three-dimensional movement of the welding torch can be realized; the control system is convenient in operation and accurate in control.

Description

technical field [0001] The invention relates to a method and a device for repairing a large gear in a mechanical system, in particular to a repair welding method and a device for a large gear with involute straight teeth. Background technique [0002] When the tooth surface of the gear is worn, the gear not only cannot operate normally, which affects its working accuracy, but also may cause vibration and noise of the machine. The wear of the gear surface will cause the scrapping of the entire gear parts, which greatly reduces the utilization rate and work efficiency of the equipment. The repair of worn gears is of great significance to improve production efficiency and reduce production costs. Tooth flank wear can allow gears to be reused with proper repair. Repairing gears saves more money than manufacturing them. [0003] Patent Publication (Announcement) No.: CN103292673A, which discloses a "method and device for detecting tooth surface wear of involute spur gears", wh...
