Automatic turning gear for gearbox of wind generating set

The automatic turning gear comprises a box body, a fixing support is installed on the side wall of the box body, a plurality of installation supports are fixed to the side wall of the fixing support, and a protection plate is fixed to the ends of the installation supports jointly. And a driving mechanism, a turning mechanism and a control mechanism are arranged on the side wall of the fixed support. The gear transmission box has the advantages that lubricating oil in the gear transmission box can continuously flow and transfer, the situation that the lubricating property is reduced due to accumulation is avoided, friction heat in the kinetic energy transfer process can be rapidly diffused outwards through outflow transfer, the equipment abrasion degree is further reduced, flowing of air flow around the pumping box is accelerated through rotation of fan blades, and the service life of the equipment is prolonged. Therefore, the overall heat dissipation efficiency is improved, the equipment operation damage is g
