Problems solved by technology

Due to the small matching gap between the transmission spindle and the gearbox, the above method greatly affects the assembly efficiency during the implementation process, and due to the casting error and machining error of the gearbox itself, it is difficult to quickly complete the output end of the spindle and the gear. The centering work of the input end of the box seriously affects the assembly efficiency

Abstract

The invention discloses a tool for assembling a transmission spindle and a gearbox in a wind turbine generator. The tool comprises a primary positioning mechanism, and a pull rod mechanism. The primary positioning mechanism is used for lifting and moving the transmission spindle to keep the axis of the transmission spindle to be horizontally level to the axis of the gearbox, and slightly inserting the transmission spindle into a locking disk hole of the gearbox. The pull rod mechanism comprises a pull rod which can penetrate through a cable hole on the transmission spindle and a cable hole on a hollow shaft of the gearbox. One end of the pull rod is provided with a top ring which can overlap with the large end of the transmission spindle. The other end of the pull rod is in threaded structure on which a locknut is fitted. A protective hoop is sleeved on the pull rod inside the locknut and is used for contacting with the outer wall of the gearbox so as to locate the hollow shaft of the gearbox inside the protective hoop. The invention further discloses an assembly method of the assembly tool. By the use of the tool and method, fast assembly is achieved with guaranteed assembly precision and with no damage to the transmission spindle and the gearbox, and assembly efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of wind turbine assembly, and relates to an assembly tool and an assembly method, in particular to an assembly tool and an assembly method for a wind turbine drive shaft and a gear box. Background technique [0002] The transmission system of the double-fed wind turbine mainly includes the impeller, the transmission main shaft, the bearing housing and the main gearbox. The impeller converts the wind energy into mechanical energy, which is then transmitted and transformed by the transmission main shaft and the gearbox, and finally converted into electrical energy by the generator. . Therefore, the assembly accuracy of the drive shaft and the gearbox plays a very important role in the energy transfer of the wind turbine. The assembly of the current transmission spindle and the gearbox is mainly realized by positioning tooling. The so-called positioning tooling is to make a set of brackets according to the characteristi...
