摘要： A ceiling fan or ceiling fan assembly can include a motor to rotatably drive a set of fan blades. The set of fan blades are attached to the motor via a blade iron, which mounts the blades to a rotating rotor of the motor. A grommet is provided within holes of the blades, between the blade and a fastener, to reduce vibration and improve dampening at the junction between the blades and the motor. Multiple flanges are formed at the end of each grommet. The multiple flanges provide for improved compressibility to improve ease of installation, which resisting sliding of the grommet from the holes in the blades.

摘要： A ceiling fan or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. A blade iron can couple the blades to the motor. A connection assembly provides for connecting the ceiling fan blade to the blade iron. The connection assembly provides for aligning the blade with a set of fingers and can slide from a first position to a second position to secure the blade to a blade iron.

摘要： A ceiling fan having double-layer blades includes a motor unit, a blade frame unit, a first blade unit, and a second blade unit. The blade frame unit has a blade frame body. The first blade unit includes a plurality of first blades. The second blade unit includes a plurality of second blades. The first blades and the second blades surround the outside of the blade frame body, so that there is no need for the motor unit to provide a motor housing for connecting the first blades and the second blades, thereby saving costs and installation costs. With the arrangement of the first blades and the second blades, the ceiling fan can increase the current of air for cooling.

摘要： A ceiling fan or blade thereof can include a fan motor for rotating the blade. The blade can include an airfoil body having an outer surface extending between a leading edge and a trailing edge, and a root and a tip. The blade can be separated into three distinct cross sections including a first cross section as a lifting cross section, a second cross section as a flat cross section, and a third cross section as a transition section between the first and second cross sections.

摘要： A fan assembly for a gas turbine engine includes a fan disk, a trunnion, a fan blade, and a counterweight assembly. The fan disk is configured to rotate about an axial centerline of the gas turbine engine when installed in the gas turbine engine. The trunnion is mounted to the fan disk and defines a slot extending through a portion of the trunnion. The fan blade defines a pitch axis and is rotatably attached to the fan disk about its pitch axis through the trunnion. The counterweight assembly includes a link arm extending to the trunnion and an engagement device mounted to the link arm that is disposed to move through the slot of the trunnion.

摘要： A fan includes a motor, a rotatable hub coupled to the motor, and at least one fan blade. The at least one fan blade includes a first end coupled to the rotatable hub, a second end, a leading edge, a trailing edge, a passage extending from the first end to the second end, and a winglet attached to the second end. At least one flexible strap extends through the passage of the at least one fan blade. The flexible strap is coupled at a first end to the rotatable hub and coupled at a second end to the winglet, such as to an inner portion thereof within the passage.
