Description

Technical Field

[0001] The present application relates to the technical field of gear boxes, and in particular to an improved sootblower gear box. Background Art

[0002] Gearboxes are widely used, for example, in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Their main function is to transfer the power generated by the wind wheel under the action of wind to the generator and make it get the corresponding speed.

[0003] Traditional sootblower gearboxes usually use a single fixed key to fix the worm gear. This fixing method is easily affected by impact and load during long-term operation, resulting in unstable operation of the gearbox and poor overlap of the sootblowing trajectory, which in turn affects the sootblowing effect and equipment life.

[0011] Furthermore, ropes are fixedly connected to the side surfaces of the two clamping plates that are close to each other, and the two ropes completely penetrate the first sealing cover.

[0012] Through the above solution, the installation rope can separate the sealing cover from the housing when the rope is pulled, thereby achieving the purpose of rapid disassembly.

[0013] Furthermore, a second sealing cover is provided inside the housing, the second sealing cover is connected to the sliding bushing via bolts, and the second sealing cover is rotatably connected to the main shaft via a bearing.

[0018] Through the above solution, the cooperation between the buffer groove, the buffer member and the buffer spring can buffer the vibration generated when the main shaft is working, thereby improving the stability of the shell.

[0019] Furthermore, a plurality of bottom plates distributed at equal distances are provided below the shell, and the plurality of bottom plates are fixedly connected to the buffer members adjacent thereto, and the bottom surfaces of the plurality of bottom plates are fixedly connected to two suction cups.
