Abstract
Ceiling fan consisting of a rotatable assembly to which the fan blades are attached and a stationary assembly connected to capable of being connected to a suspension means. These assemblies have a common centerline, and the rotary assembly comprise the rotor and the stationary assembly the stator, located concentrically inside the rotor, of an electric motor. The rotatable assembly is mounted rotatable relative to the stationary assembly by means of a tubular member extending coaxially with the centerline and a shaft located therewithin. Two bearings are located at a distance one above the other and are mounted between the shaft and the tubular member, at least one of which bearings comprises a rolling bearing. The other one of the two bearings comprises a journal bearing.
Claims7
Ceiling fan comprising a stationary assembly adapted to be connected to a suspension means and a rotary assembly including a series of fan blades, the rotary assembly including a rotor and the stationary assembly including a stator of an electric motor, a unitary mounting assembly supporting said rotatable assembly relative to the stationary assembly including an elongated tubular member extending coaxially with the common center line of the rotor and stator, a shaft mounted in the tubular member and two spaced bearings located at a distance spaced axially distance from one another between the shaft member and the tubular member, at least one of the bearings comprising a rolling bearing and the other one comprising a journal bearing, a housing including an end dish having a peripheral flange, means defining a series of circumferentially spaced indentations adjacent the lower edge of the flange and a plurality of slotted openings in the upper peripheral edge of the flange aligned with said indentations and hook shaped mounting brackets having portions engaging in said openings and indentations respectively and means for clamping a fan blade between said bracket members.
