Abstract
A collar is to be positioned on a generator and includes an inner bore sized to be received on an outer periphery of a generator shaft. The collar has an outer periphery, which is generally hexagonal. The collar has an axially extending ledge to be received within an inner periphery of an end turn support in a generator.
Claims15
A collar to be positioned on a generator, said collar comprising:
- an inner bore sized to be received on an outer periphery of a generator shaft;
- and
- said collar having an outer periphery, which is generally hexagonal, and said collar having an axially extending ledge which is to be received within an inner periphery of an end turn support in a generator, said ledge being cylindrical, and of a smaller outer diameter than said hexagonal outer periphery.
A generator comprising:
- a plurality of coils, an end turn support for supporting axial ends and an inner periphery of said plurality of coils;
- a rotating shaft for rotating with said plurality of coils;
- and
- a collar having an inner peripheral bore sized to be received on an outer periphery on said generator shaft, and an insulator spaced from said collar in a direction away from said plurality of coils, said collar having a ledge extending within an inner peripheral bore of said end turn support, and an enlarged outer face for facing an end of said end turn support.
1 more element
An insulator and collar combination comprising:
- a collar having an inner bore centered on an axis, and an outer periphery, which is generally hexagonal, and said collar having a cylindrical axially extending extension which is to be received within an inner periphery of an end turn support in a generator;
- and
- an insulator to be associated with said collar on the shaft, said insulator having a radially enlarged portion and an extension portion to extend toward said collar.
