Abstract
The invention discloses a combined wind power wind wheel lock disc which comprises a lock disc body, linings, screws and grease cups. When a wind driven generator conducts daily operation, lubricating grease is injected into the grease cups regularly, so that the inner surfaces of the linings are prevented from being rusted. Lubricating grease injection holes and grease guide holes are machined in the linings of the wind wheel lock disc so that a lubricating medium can be conveyed to contact faces between locking pins of a wind wheel locking mechanism and inner cone holes of the linings, and the friction resistance of inserting and retreating of the locking pins is effectively relieved. The wind wheel lock disc is provided with unlocking bolt holes, when the locking time of a wind wheel is relatively long and loads are excessively large, the locking pins of the wind wheel locking mechanism are hard to retreat, unlocking bolts can be used for disengaging the locking pins from the linings, and the purpose of relieving locking of the wind wheel is achieved. A combined structural form is adopted for the wind wheel lock disc so that the phenomenon that the wind wheel locking mechanism is stuck due to the surface corrosion of a halting hole of the wind wheel lock disc can be prevented, and the safety and reliability of a wind driven generator set are improved.
