Wind power gearbox loading test device and test method

Abstract

The invention discloses a wind power gearbox loading testing device and a wind power gearbox loading testing method. The wind power gearbox loading testing device comprises the components of a driving motor, a first universal coupling, a testing accompanying gearbox, a first low-speed connecting shaft, a second low-speed connecting shaft, a main tested gearbox, a second universal coupling and a loading motor. The driving motor is connected with the testing accompanying gearbox. The testing accompanying gearbox is connected with the first low-speed connecting shaft. The second low-speed connecting shaft is connected with the main tested gearbox. The main tested gearbox is connected with the loading motor. The free ends of the first low-speed connecting shaft and the second low-speed connecting shaft are respectively provided with a first large flange and a second large flange. The first large flange is transmissibly connected with the second large flange. Supporting roller assemblies which abut against the left side and the right side of the first large flange and the second large flange are arranged below the left side and the right side of the first large flange and the second large flange. The wind power gearbox loading testing method comprises respectively placing the two supporting roller assemblies below the left side and the right side of the first large flange and the second large flange and fastening the two supporting roller assemblies on the testing platform. The wind power gearbox loading testing device and the wind power gearbox loading testing method can simulate the main shaft bearing supporting rigidity of a wind turbine generator system and furthermore realize high convenience in mounting and detachment.

Description

technical field [0001] The invention relates to a gear box loading test verification tooling equipment, in particular to a wind power gear box loading test device and a test method thereof. Background technique [0002] Wind power gearboxes need to be verified by loading tests before they leave the factory. Usually, two gearboxes are installed back-to-back to achieve mutual loading. When installed back-to-back, the low-speed shafts of the two gearboxes are connected to each other. In an existing technical solution, there is no support at the low-speed shaft at all. The disadvantage is that the support stiffness of the gearbox at the low-speed stage is weaker than that of the wind turbine, which may cause excessive vibration or occurrence of Abnormal resonance affects the loading test results of wind power gearbox. In another existing technical solution, a bearing device is installed on the low-speed shaft, but its support position is usually inconsistent with the support po...

In an existing technical solution, there is no support at the low-speed shaft at all. The disadvantage is that the support stiffness of the gearbox at the low-speed stage is weaker than that of the wind turbine, which may cause excessive vibration or occurrence of Abnormal resonance affects the wind power gearbox loading test results

In another existing technical solution, a bearing device is installed on the low-speed shaft, but its support position is usually inconsistent with the support position of the main shaft bearing on the wind turbine. In addition, this solution must use a larger bearing that is equivalent to the size of the main shaft bearing of the wind turbine. High cost and difficult to install and disassemble
