Embodiment Construction
[0049] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.
[0050] Such as figure 1 with figure 2 As shown, the present application provides an auxiliary tool 100 for installing the expansion sleeve of the wind turbine gearbox. The auxiliary tool 100 includes a hydraulic wrench mount 200 and a fixing frame 300 . The hydraulic wrench mount 200 is used for installing a hydraulic wrench 400 . The hydraulic wrench 400 is used to tighten the expansion bolts on the expansion sleeve. The hydraulic wrench mounting seat 200 is provided with a mounting port for installing the hydraulic wrench 400. The mounting port runs through the hydraulic wrench mounting base 200 along the axial direction of the expansion sleeve. Each opening can be installed with a hydraulic wrench 400. In this embodiment, four installation openings are opened on the hydraulic wrench installation base 200, and the insta...

The auxiliary tool comprises a hydraulic wrench mounting seat and a fixing frame, a mounting opening used for mounting a hydraulic wrench is formed in the hydraulic wrench mounting seat, the first end of the fixing frame is used for being connected with a gearbox, and the second end of the fixing frame is used for being connected with the gearbox. The second end of the fixing frame is movably connected with the hydraulic wrench mounting seat; the fixing frame is provided with a plurality of installation positions in the circumferential direction of the expansion sleeve, and the installation opening can be switched among the multiple installation positions. According to the auxiliary tool for installing the expansion sleeve of the gearbox of the wind turbine generator, the fixing frame is arranged to be fixedly connected with the gearbox, the hydraulic wrench installing base is arranged to be used for installing a hydraulic wrench, an operator does not need to hold the hydraulic wrench by hand to tighten a bolt on the expansion sleeve, and the labor intensity of the operator is reduced; and the screw tightening efficiency is improved.
Description
technical field [0001] The invention relates to an auxiliary tool for installing an expansion sleeve of a wind turbine gearbox. Background technique [0002] In the drive chain structure of wind turbines, the main shaft is generally connected to the transmission shaft through expansion sleeves to transmit torque. However, there are multiple bolts on the expansion sleeve along the circumferential direction, which need to be tightened several times to achieve the predetermined clamping force, and in order to ensure tightening, the prior art relies on the operator to tighten the bolts of the expansion sleeve one by one with a hydraulic wrench In this way, the labor intensity of the operators will be relatively high; in addition, due to the need for multiple fastenings in the shape of a diagonal square, two staff members are required to operate the hydraulic wrench, and only two bolts can be fastened at a time, so the work efficiency is low.
