20080292230 | Lubricated bushing - A lubricated bushing is mounted in a mounting cavity in a bushing housing and has a body and a flange. The body has an axial hole formed coaxially through the body to rotatably hold a shaft of a rotor of a fan and a bottom concentric recess formed in a bottom end of the body. The flange is formed on and protrudes radially out from the outer wall of the body, is mounted against an inner wall of the mounting recess, extends longitudinally from the top end of body and is shorter than half the body. Even though the inner wall of the mounting cavity tightly compresses the flange, the compressive force cannot be effectively transmitted to the body to deform the axial hole, so the shaft is kept from seizing up in the axial hole. | 11-27-2008 |
