Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.
[0024] see figure 1 , a stress-free installation method for a wind power main gear box, the method includes pasting a strain gauge 5 at the transition arc between the torque arm 4 and the box body; carrying out stress calibration, gearbox trial installation and stress testing on the strain gauge 5 , to obtain the relationship between the installation stress and the thickness of the gasket; and according to the relationship between the installation stress and the thickness of the gasket, select a gasket with a thickness corresponding to zero installation stress for installation and test verification.
[0025] The method specifically includes the following steps:
[0026] The first step, work preparation: Paste the strain gauge 5 at the transitional arc of the connection between the torq...

The invention discloses a stress-free installation method for a wind power main gear box. The method comprises the steps that a strain gauge is pasted to a transition arc of the connecting portion ofa torque arm and a box body; the relation between the installation stress and the gasket thickness is obtained by conducting stress calibration, gearbox trial installation and stress testing on the strain gauge; and a gasket with the thickness corresponding to the zero installation stress is selected according to the relation between the installation stress and the gasket thickness to be installed, tested and verified. The method has the beneficial effects that the purpose of stress-free installation of the wind power main gear box can be achieved, the process is simple and clear, the hidden danger of installation stress concentration of the torque arm of the gear box after installation is avoided, and the service life can be effectively ensured.
Description
technical field [0001] The invention relates to a wind power gearbox manufacturing technology, in particular to a stress-free installation method for a wind power main gearbox. Background technique [0002] The continuous improvement of wind power equipment manufacturing and installation technology and capabilities has promoted the rapid development of the entire wind power industry. With the development of the industry, the requirements for the installation and leveling of components for the installation of the whole machine have also increased. Such as figure 1 As shown, the main gearbox of the fan is mainly installed and fixed by the two main bearing seats of the front bearing seat 1 and the rear bearing seat 2, which are used to support the main shaft and are fixed on the frame. The torque arm 4 on the box behind the rear bearing seat It is connected with the frame through the elastic support assembly 3 fixed on the frame. The traditional installation method for fan m...
