Wind Turbine

A wind turbine, comprising:

• a swivel assembly including:
• a swivel plate having a swivel plate top surface opposite a swivel plate bottom surface;
• a tubular sleeve joined to said swivel plate and extending through said swivel plate, said tubular sleeve having a tubular sleeve external surface and a swivel sleeve internal surface defining a tubular sleeve passage extending axially through said swivel plate;
• an annular member joined to and extending through said upper platform of a support tower, said annular member having an annular member internal surface concentrically disposed about said cylindrical swivel sleeve external surface defining an annular space between said cylindrical annular member internal surface and said cylindrical swivel sleeve external surface,
• said annular member including an annular member shoulder extending radially inward from said annular member internal surface,
• said tubular sleeve including a tubular sleeve shoulder disposed medially between a tubular sleeve first end and a tubular sleeve second end and extending radially outward of the tubular sleeve external surface,
• said annular member shoulder axially aligned in opposed relation a distance from said tubular sleeve shoulder disposes said swivel plate a distance from said upper platform,
• a first bearing including a first bearing inner race rotatable within a first bearing outer race, said first bearing inner race engaging said tubular sleeve external surface and said first bearing outer race engaging said annular member internal surface;
• an annular spacer having an annular spacer internal surface engaging the tubular sleeve external surface and radially outwardly extending to an annular spacer outer surface joining opposite annular spacer first and second sides, said annular spacer first side in contact with said first bearing inner race of said first bearing;
• a second bearing including a second bearing inner race rotatable within a second bearing outer race, said second bearing inner race of said second bearing in contact with said annular spacer second side;
• and
• a collar threadingly coupled about said tubular sleeve second end, said collar contacting said second bearing inner race, thereby disposing in fixed axial and radial spatial relation the tubular sleeve and the tubular member, whereby the tubular sleeve can rotate within the tubular member.
