Abstract

1,195,295. Resiliently mounting electric motors. SMITHS INDUSTRIES Ltd. 31 Jan., 1969 [8 Dec., 1967], No. 55971/67. Heading H2A. [Also in Division F1] In a centrifugal fan or blower the impeller 18, Fig. 1, and its driving motor 15 (e.g. a threephase electric motor) are mounted within a casing by a number of resilient vibrationabsorbing mountings 16 each comprising a wire loop 20 and a resilient pad 26 secured either to the motor as shown, or to the casing. The loop 20 comprises a portion 22 having a pair of parallel limbs, and a portion 21 with its two limbs defining a key-hole shape, Figs. 4 and 5 (not shown). The pad 26 is rectangular and receives the limbs of the portion 22 in passages or in longitudinal grooves formed in its sides. The portion 21 is received in a peripheral groove in a cylindrical resilient pad 31. The pads 26, 31 may be of natural rubber and are respectively secured by bolts 29, 23 which compress the pads about the wire loop portions 22, 21. The latter may be joined in spaced relationship by a further portion (32), Fig. 7 (not shown), arranged at 45 degrees to the portions 21, 22. Alternatively, both portions 21, 22 may be of parallellimb form. The casing is of volute form and comprises at least one axial inlet 13 and an outlet 14. Air entering through the right-hand inlet cools the motor 15, the motor end plates having apertures therein for the passage of cooling air. An earthing strip 30 is provided at the lower mounting 16.
