Abstract

1510739 Centrifugal fans ROBERT BOSCH GmbH 14 May 1975 [19 July 1974] 20292/75 Heading F1C A sheet metal fan wheel comprises vanes 12 bent out of a disc-like part 11, a stiffening corrugation 14 having a substantially trapezoidal crosssection and associated with each vane extending generally radially in the disc-like part and bridging the bend line between the respective vane and the disc-like part. The corrugation 14 may slope towards the disc-like part 11 over the region 23 in order to reduce stress occurring in the transition zone between the corrugation and the disc-like part adjacent that region.
