Power switchgear casing with driving cranks releasable from shaft - has bore through each crack for fixing bolt extending through common coupling rod into blind hole in casing

摘要

The jointed transmission casing (5) incorporates a blind hole into which an overlong fixing bolt can be fitted while it is pushed through a bore in the crank (4). A number of such casing can be installed on a common support (3) with cranks (14) similarly fitted to a coupling rod (11). Each crank is set to a particular position by insertion of the fixing bolt into its blind hole. The rod determines the distance between casings before they are secured. ADVANTAGE - Less complex structure enables switchgear to be set and transported in defined position.
