Description

Wind-powered barring driving clutch base

Technical Field

The utility model relates to the technical field of wind generating set accessories, in particular to a wind power barring driving clutch base.

Background

When the wind turbine generator system is used for maintaining the wind turbine, the wind turbine needs to be turned, and after the locking holes are aligned, the locking pin locks the wind turbine, so that personnel can enter the wind turbine to perform related operations. Due to the heavy weight of the wind wheel of the large megawatt unit, workers usually need to jiggle the wind wheel by means of a jigger device. One of the common barring methods is to use a barring drive (a pinion is mounted at a drive end of a speed reducer) to drive a high-speed brake disc with teeth on an outer ring to perform barring.

Because the pinion on the barring drive and the big tooth of the high-speed brake disc are in open transmission and are not lubricated, in order to reduce the abrasion of the gear, the barring drive pinion and the big tooth of the brake disc are required not to be in a meshing state when the unit normally operates. It is common practice to remove the small teeth of the barring drive when not barring, however this is inconvenient in the following ways: 1. the jigger driving pinion is heavy and inconvenient to lift; 2. the gear is tightly matched with the driving shaft, and tools are needed, so that the assembly and disassembly are inconvenient; 3. the space is dismantled on platform upper portion is limited, and personnel can't be located the barring drive dead ahead and dismantle, and operating personnel need dismantle to the cabin bottom down.
