摘要： A medallion-style blade iron assembly for use on a ceiling fan includes a vibration isolation system for eliminating transmission of vibration from the fan motor to the blades. The assembly includes an arm securable to the fan motor and medallion securable to the arm, with the distal end of a blade being secured therebetween. A plurality of mounting holes are provided in the blade for allowing screws to be inserted through the arm into the medallion, with each hole have a resilient elastomeric grommet disposed therein. Each grommet has a pair of annular shoulders resting on the top and bottom surfaces of the blade, and a central tapered opening for receiving the frusto-conical bosses formed on the arm and medallion. The grommets prevent contact between the blade, the arm, and the medallion.

摘要： A rotor assembly for supporting rotor blades includes a plurality of axially adjoining discrete disks each having a rim, web, and hub. The rims include axial dovetail grooves for collectively supporting a respective blade dovetail therein. Each of the disks includes at least one axially extending annular arm joined integrally with the disk and fixedly joined to an adjacent one of the arms. The disks are fixedly joined together solely by the blade dovetails in the rim dovetail grooves and by the arms so that upon a crack failure of one of the disks, centrifugal load from the failed disk is transferred to an adjacent disk.

摘要： The invention concerns a structure for mounting a fan to a fan motor. The structure is designed to fit a plurality of thrust washers onto the end of a motor shaft supported in a casing through a bearing and to thrust and fit a flat washer on a peripheral surface of a smaller diameter step formed on the tip side further than the washers-fitted section. Of these thrust washers, the most outer, tip side, thrust washer located opposite to the flat washer is thicker than the traveling play distance toward the core of a motor shaft and thinner than the interval from the adjacent thrust washer to the peripheral surface of the step. With the construction, hence, the invention serves to prevent the thrust washer from falling onto the smaller diameter step.
摘要翻译：本发明涉及一种用于将风扇安装到风扇马达的结构。该结构被设计成将多个止推垫圈安装在通过轴承支撑在壳体中的马达轴的端部上，并将平垫圈推压并安装在形成在尖端侧的较小直径台阶的周边表面上垫圈部分。在这些止推垫圈中，与平垫圈相对的最外侧的尖端侧止推垫圈比朝向电动机轴芯的行进游隙更薄，比从相邻止推垫圈到周边表面的间隔更薄步。因此，本发明的目的在于防止止推垫圈落入较小直径的台阶上。

摘要： A system for fabricating fan blades wherein the assembly includes a flat hub plate having generally radially oriented notches defined therein intersecting the plate periphery. Individual blades each include a hub connection portion adjacent an inner end region which includes parallel flat portions angularly related to the general blade configuration interconnected by a transition portion. The flat blade portions are located upon opposite sides of the hub plate and the transition portion extends through the hub plate notch. The flat portions are attached to the hub plate, and by predetermining the position of the hub connection configuration on the blade, the fan characteristics can be predetermined and accurately duplicated. The system permits a standard set of tools to form a variety of sizes of fan blade components having various characteristics.

摘要： A method for assembling a plurality of bucket assemblies having tangential entry dovetails onto a wheel of a turbomachine such that a predetermined circumferential force is obtainable on the bucket assemblies when assembled, includes reducing the distance between lateral faces on the base portion of at least a first bucket assembly and preferably all bucket assemblies, such as by cooling, and increasing the distance between the lateral faces after assembly, so that the predetermined circumferential force is obtained. Alternatively, the wheel circumference may be increased as by heating before the bucket assemblies are assembled. A combination of appropriate heating and cooling may be used. A closure piece having a predetermined circumferential expanse may be inserted in the bucket row of the wheel to obtain the desired circumferential force.
