Background
The wind generating set has great vibration when working, and under the combined action of wind power and generating set vibration, the wind power equipment cabin is often in a swinging environment. A crane matched with an offshore wind generating set is determined to adopt a manual beam type structure form after demonstration. The running trolley is arranged on the main beam and can move along the main beam. The girder is installed and can follow the walking guide rail and remove on the walking guide rail to satisfy the demand of different position operations of lifting by crane. The crane is a precondition for safe operation of the crane by ensuring that the main beam and the running trolley of the crane can run in a preset direction without sliding (namely, the main beam or the running trolley can not move by self when not obtaining driving force). In the project, the problem of driving the main beam and the running trolley to move is solved by adopting a chain transmission mode.

After the driving chain wheel group, the guide chain wheel group and the tensioning chain wheel group are installed, the working planes of the chain wheels (the plane where the wheel width center of the chain wheel after the chain wheel is installed) on the driving chain wheel group, the guide chain wheel group and the tensioning chain wheel group are not coincident, the main beam moves along the walking guide rail under the traction of the transmission chain, a certain gap exists between the flange of the main beam and the guide rail, and the working plane (the plane where the center of the transmission chain is located) of the transmission chain can deviate along with the movement of the main beam. When deviation and deflection are accumulated to a certain degree, undercutting can occur when the transmission chain is meshed with each chain wheel on the driving chain wheel set (or the guide chain wheel set) and the tensioning chain wheel set, so that the abrasion between the chain wheels and the transmission chain is increased, and the transmission chain can fall off from the driving chain wheel (or the guide chain wheel) to cause chain transmission failure in severe cases. In order to ensure the safety and reliability of the chain transmission with the ultra-large center distance, the transmission chain must be ensured not to fall off in the chain transmission process.
