Abstract
A securing system for a fan assembly. The securing system includes a first member which attaches to a motor mount and a second member which attaches to the hub of the fan assembly. The first member is interposed between the hub and the second member such that should the shaft of the motor break, the first and second members engage with one another and inhibit the fan assembly from falling away from the motor mount.
Claims20
An industrial fan comprising:
- a mounting assembly that is adapted to mount a fan to a surface of a building;
- a motor that is mounted to the mounting assembly, wherein the motor defines a shaft;
- a hub assembly that couples to the shaft of the motor such that rotation of the motor shaft results in rotation of the hub;
- a plurality of fan blades that mount to the hub assembly;
- and
- a securing assembly interposed between the hub and mounting assembly, wherein the securing assembly comprises a first member that is coupled to the hub and a second member that is coupled to the mounting assembly and wherein the first and second members engage with each other such that the hub is inhibited from falling when the motor shaft breaks or the hub otherwise disengages from the shaft and wherein the second member is interposed between the first member and the hub.

A fan assembly comprising:
- a motor that is adapted to be mounted to a building surface, wherein the motor includes a housing and motor shaft that extends in a first direction;
- a hub assembly that is adapted to be coupled to the motor shaft;
- a plurality of fan blades that are adapted to be coupled to the hub assembly;
- a first securing member that is mechanically coupled to the hub;
- a second securing member that is adapted to be mechanically coupled to the motor housing, wherein the second securing member is interposed between the first securing member and the hub such that, in the event of the motor shaft breaking or the hub otherwise disengaging from the shaft, the second securing member engages with the first securing member so as to inhibit the hub assembly from falling.
