Definitions
- the present invention relates to a fan suspension system for reducing vibration on the supporting frame induced by rotation of the electric motor shaft and the masses, e.g. the fan impeller, connected to it.
- Severe vibration may be generated in particular when the electric motor shaft rotates at high speed.
- one or more elastic members metal springs or rubber pads
- the present invention may be used to advantage in a fan associated with a combustion unit, in which reducing vibration, and therefore noise, is particularly important.
- number 10 indicates a fan to which is applied a first embodiment of a suspension system 100 for an electric motor 11 enclosed in a casing 12 supported by a partly sectioned "cup-shaped" member 13 ( Figure 1).
- the innovative system 100 will be described in detail later on.
- electric motor 11 rotates a drive shaft 14, which is fitted with an impeller 15 enclosed in a housing 16 having a scroll.
- housing 16 comprises a first "cup-shaped" portion 16a, and a second portion 16b in the form of a cover; and the two portions 16a, 16b are fixed to each other by conventional means (not described) to enclose impeller 15.
- member 13 houses, inside a seat 17, a bearing 19 supporting drive shaft 14.
- the three elastic members 20 are made of rubber or any elastomeric material, and each surrounds a pin 20a screwed to the outer end of first portion 16a by a respective screw 21 ( Figure 3).
- each elastic member 20 comprises a substantially cylindrical main body 20b, in which is formed a circumferential groove 20c.
- each elastic member 20 is inserted inside a corresponding seat 21a formed in "cup-shaped” member 13; and circumferential groove 20c engages the walls of respective seat 21a to elastically secure housing 16 with respect to "cup-shaped" member 13 as required.
- the term "suspended mass” in the present context is intended to mean the whole defined by electric motor 11, casing 12, "cup-shaped” member 13, drive shaft 14, and impeller 15, and which is substantially symmetrical with respect to the longitudinal axis (a) of drive shaft 14.
- system 100 comprises at least one damping member 20 interposed between housing 16 housing impeller 15, and member 13 housing and supporting electric motor 11.
- Figure 7a shows vibration, along the Y axis, with respect to the speed of drive shaft 14, along the X axis; and the comparison was made between a fan 10 in accordance with the present invention and fitted with suspension system 100 described, and the same fan fitted with a prior-art suspension system.
- the vibration detecting device (not shown) was placed on casing 12 of electric motor 11.
- Figure 7b shows vibration (along the Y axis) with respect to the speed of drive shaft 14, but, in this case, with the detecting device on housing 16.
- toroidal member 22 is inserted inside a seat 23 formed in "cup-shaped" member 13, and, as shown in Figure 6, is fixed to first portion 16a by three screws 24.
