Method and device for disassembling gear box of wind driven generator

Abstract

The invention relates to a method for disassembling a gear box of a wind driven generator, which comprises the following steps of: a, suspending the gear box on a crane arm through a rope; b, loosening an expansion sleeve and a nut on an elastic supporting seat to ensure that the gear box is detachably connected with an underframe of a forward engine room; and c, respectively arranging a hydraulic jack on two sides of an output shaft of a wind wheel, wherein the bottom end of each hydraulic jack is fixed with the underframe of the forward engine room, and the top end is in contact with the gear box. A device for disassembling the gear box of the wind driven generator comprises two hydraulic jacks connected with a hydraulic pump station and is characterized in that the hydraulic jacks are fixedly arranged on a supporting device, top ends of piston rods of the hydraulic jacks are fixedly provided with fixed blocks, and the supporting device comprises a first supporting block, a second supporting block and a connecting shaft. The method and the device can realize the independent disassembly of the gear box during the user period without disassembling the engine room, thereby shortening the maintenance time and lowering the maintenance cost.

Description

technical field [0001] The present invention relates to a method and a device for disassembling a gearbox of a wind-driven generator, and more specifically, to a method and a device for disassembling a gearbox of a wind-powered generator for realizing disassembly by using a hydraulic jack. Background technique [0002] The gearbox in the wind turbine is an important mechanical component, and its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it obtain a corresponding speed. The speed of the wind wheel is very low, which is far from meeting the requirements of the generator to generate electricity. It must be realized through the speed-up effect of the gear pair of the gearbox. Since wind turbines are usually installed in high mountains, wilderness, beaches, islands, etc., the gear box is subjected to the wind force of irregular changing direction and load and the load impact of strong gusts. The prob...

Problems solved by technology

Since wind turbines are usually installed in high mountains, wilderness, beaches, islands, etc., the gear box is subjected to the wind force of irregular changing direction and load and the load impact of strong gusts. The probability of gearbox failure during the 20-year operating life is very high. In addition, the natural environment where the transportation is inconvenient. The gearbox is installed in a small space on the top of the tower. Once a failure occurs, it is very difficult to repair
