Abstract (en)
[origin: JPH02101721A] PURPOSE: To enable a support arm for a contact bridge to be surely fixed to a changing shaft, by a method wherein a projection engaged with a corresponding recess provided to a changing shaft is provided to a flange, and the flange is firmly linked to a changing shaft with a self-curing insulation band impregnated with resin. CONSTITUTION: A contact bridge 6 is supported and guided by a support arm 7 mounted on a changing shaft 3. All the arm 7 formed of insulating material is mounted on the changing shaft 3 together with a flange 8 suitable for the tubular changing shaft 3, nearly occupying one-third (nearly angle of 120 deg.) of the circumference of the changing shaft 3. Furthermore, a projection 9 is provided to the flange 8 of the support arm 7 and engaged with a corresponding recess provided to the changing shaft 3. Moreover, the support arm 7 is fixed to the changing shaft 3 with a self-curing insulating band 10 impregnated with resin. Therefore, the insulating material band 10 is wound around the flange projection 11 of the support arm 7 and the changing shaft 3.
