Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
Fig. 1 and 2 schematically show a device for wind turbine bearing protection according to an embodiment of the present invention. As shown in fig. 1 and 2, the device for protecting the bearing of the wind turbine generator comprises a hoop 1, a side wing 3 and an extension bolt 8.
The hoop 1 comprises two symmetrical semi-hoops 1 and a semi-hoop buckling connection. Half staple bolt 1 half staple bolt includes the circular arc type body and outwards extends respectively by the both ends of body has first connecting plate and second connecting plate. The shape of the cavity formed by the arc-shaped bodies of the two half hoops 1 is matched with the external profile of the bearing, so that the bearing can be stably placed in the cavity formed by the two half hoops 1. The inner ring of the hoop 1 is embedded with a copper sheet protective layer 2 with the thickness of 3 mm. Specifically, the inner wall of the cavity formed by the arc-shaped bodies of the two half hoops 1 and the half hoops is provided with a copper sheet protective layer 2 of 3 mm. The first connecting plate of two half hoops 1 is connected with the spring washer 6 through the hexagon head bolt 5, the hexagon nut 7. Two threaded holes used for accommodating the hexagon head bolts 5 are formed in the first connecting plates of the two half hoops respectively. The hexagon head bolt 5 sequentially penetrates through the threaded holes on the two first connecting plates to be in threaded connection with the hexagon nut 7. A spring washer 6 is arranged between the head of the hexagon head bolt 5 and one of the first connecting plates. The second connecting plate of the two half hoops 1 is connected with the spring washer 6 through the hexagon head bolt 5 and the hexagon nut 7. Two threaded holes used for accommodating the hexagon head bolts 5 are formed in the second connecting plates of the two half hoops respectively, the hexagon head bolts 5 sequentially penetrate through the threaded holes in the two second connecting plates and are in threaded connection with the hexagon nuts 7, and a spring washer 6 is arranged between the head of the hexagon head bolt 5 and one of the second connecting plates.
