Gear ring nitriding process and equipment for wind power generation

Abstract

The invention relates to a gear ring nitriding process and equipment for wind power generation, and belongs to the technical field of gear ring nitriding processes. The equipment comprises a roller conveyor, a cleaning device, a drying device, a clamping device, a coating device and a nitriding device. The clamping device comprises a guide rail laid on the ground, a base frame in sliding connection with the guide rail, a driving air cylinder vertically arranged on the base frame and a base plate connected to a piston rod of the driving air cylinder. Two parallel sliding plates are in sliding connection with the base plate, the opposite sides of the two sliding plates are rotationally provided with center shafts, the center shafts are provided with clamping plates and driven gears, the sidewalls of the sliding plates are provided with first servo motors, motor shafts of the first servo motors are connected with driving gears, the driving gears are connected with the driven gears through tooth belts, the base plate is provided with two pushing air cylinders, piston rods of the pushing air cylinders are connected with the sliding plates, and the guide rail is provided with a drivingpiece used for driving the base frame to move. The gear ring nitriding process and equipment have the effect of reducing the labor intensity of workers.

Description

technical field [0001] The invention relates to the technical field of ring gear nitriding technology, in particular to a ring gear nitriding technology and equipment for wind power generation. Background technique [0002] The yaw ring gear is a key component in the yaw system of wind power equipment, and its function is equivalent to a large sliding bearing. It is located at the bottom of the nacelle seat, the lower end is fixed with the tower through bolts, the upper part supports the entire nacelle mechanism through the sliding surface, and the outer diameter teeth around it are meshed with the output gears of four yaw reducers, driven by the yaw motor to drive the nacelle mechanism The whole rotates slowly to achieve the purpose of adjusting the windward angle of the wind turbine hub. [0003] The Chinese patent with the notification number CN209494660U discloses a yaw ring gear for wind power generators, including a yaw ring gear body, the outer circumference of the y...

Problems solved by technology

[0004] In the actual processing of the ring gear, since the inner teeth of the ring gear need to mesh with other gears, in order to ensure the surface hardness of the inner teeth of the ring gear, it is usually necessary to carry out nitriding treatment on the ring gear, and the existing nitriding process mainly Including cleaning, drying, brushing, and furnace installation. Brushing refers to applying anti-seepage agent on the two end faces of the ring gear for anti-nitriding treatment. This step is mainly done manually. When the ring gear needs to be processed in large quantities , the labor intensity of the operator is relatively high
