Rotor for electrodynamic machine i.e. hydro generator, has spacing webs that are supported on rim bolts extending through sheet metal member of rotor in axial direction in order to absorb centrifugal forces that are applied to spacing webs

摘要

#CMT# #/CMT# The rotor has a sheet metal body that is composed of a set of sheet metal segments (10), which are arranged one behind the other in an axial direction. Spacing webs (14) are inserted between axially successive sheet metal segments in order to form cooling ducts. The spacing webs are supported on rim bolts (12) that extend through the sheet metal member of the rotor in an axial direction in order to absorb centrifugal forces that are applied to the spacing webs. #CMT#USE : #/CMT# Rotor for an electrodynamic machine i.e. hydro generator. #CMT#ADVANTAGE : #/CMT# The spacing webs are supported on the rim bolts that extend through the sheet metal member of the rotor in the axial direction in order to absorb centrifugal forces that are applied to the spacing webs, thus protecting the spacer webs against hazardous influence of centrifugal force that occurs during the operation of the rotor. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a rotor-sheet metal segment with spacing webs that is inserted at bolts. 10 : Sheet metal segments 11 : Groove section 12 : Rim bolts 13 : Press bolts 14 : Spacing webs 15 : Drill section.
