Problems solved by technology

After the shafting assembly is completed, it is necessary to turn the rotating part to ensure the full contact between the bearing and the raceway. However, as the size of the main shaft becomes larger and larger, the difficulty of turning becomes more and more difficult.
In addition, after the assembly of high-precision bearings is completed, the rotational torque of the shaft system needs to be detected to measure the quality of the bearing assembly. However, the conventional torque detection is to use a forklift to connect the sling to drag the shaft, and connect a tension meter between the slings. By reading the tension value, and then Multiplied by the radius of rotation to convert to torque, because the dragging process cannot guarantee uniform rotation, the measurement of the tension value is not accurate, so the measurement of the torque value is inaccurate

Abstract

The invention provides a large-scale wind driven generator shafting rotating torque measuring device. The device is used for a shafting composed of a fixed shaft and a movable shaft. The device comprises a movable shaft connecting plate, a torque sensor, a slewing bearing, a fixed shaft connecting plate and a driving motor. The end parts of the two sides of the movable shaft connecting plate are fixedly connected with the movable shaft; the top of the torque sensor is fixedly connected with the movable shaft connecting plate, and the bottom of the torque sensor is fixedly connected with the slewing bearing; the bottom of the slewing bearing is fixedly connected with the fixed shaft connecting plate; and the driving motor is arranged on the side of the slewing bearing and connected with theslewing bearing. The device has the advantages of being simple in structure, ingenious in design, convenient to disassemble and assemble, easy to operate, capable of turning the main shaft, improvingthe assembly quality and accurately measuring the torque and the like.

Description

technical field [0001] The invention belongs to the application field of wind power generators, and in particular relates to a large wind power generator shaft system rotational moment measuring device and measurement method. Background technique [0002] With the continuous development and progress of wind power generator technology, wind power generator sets are becoming larger and larger, and the size of the supporting wind power generator main bearing is gradually increasing. After the shafting assembly is completed, it is necessary to turn the rotating part to ensure the full contact between the bearing and the raceway. However, as the size of the main shaft becomes larger and larger, the difficulty of turning becomes higher and higher. In addition, after the assembly of high-precision bearings is completed, the rotational torque of the shaft system needs to be detected to measure the quality of the bearing assembly. However, the conventional torque detection is to use ...
