Abstract
A novel hob construction includes a plurality of blades and a cylindrical main body having opposite axial ends. Flanges including axially aligned slots for receiving the blades are located only upon the ends of the main body. A chocking material is provided over the circumferential extent of the main body and between the blades for forming an effective physical extension of the body for bonding the blades to the body and to each other.
Claims20
A hob for a hobbing machine, comprising:
- a cylindrical main body having a predetermined length and a circumferentially extending, non-slotted cylindrical surface;
- a plurality of blades separate from said cylindrical main body and disposed upon said cylindrical main body such that radially inner edge portions of said blades abut said non-slotted cylindrical surface of said cylindrical main body;
- flange means disposed upon opposite ends of said cylindrical main body and having a plurality of slots defined therein for receiving said plurality of blades therein, said flange means having a minor axial thickness as compared to the axial length of said cylindrical main body;
- and
- chocking material disposed about said cylindrical main body and interposed between said plurality of blades so as to be solidified in place upon said cylindrical main body and between said plurality of blades for bonding said blades to said cylindrical main body, and for bonding said blades to each other.

A hob for a hobbing machine, comprising:
- a cylindrical main body having a smooth, circumferentially continuous cylindrical surface;
- a plurality of circumferentially spaced, axially extending blades separate from said cylindrical main body and disposed upon said cylindrical main body such that radially inner edge portions of said plurality of blades abut said smooth, circumferentially continuous cylindrical surface;
- and
- adhesive chocking material disposed about said cylindrical main body and interposed between said plurality of blades so as to be solidified in place upon said cylindrical main body and between said plurality of blades for bonding said blades to said cylindrical main body, and for bonding said blades to each other.

A hob for a hobbing machine, comprising:
- a cylindrical main body having a predetermined axial length and a circumferential extent;
- a plurality of circumferentially spaced, axially extending blades separate from said cylindrical main body and disposed upon said cylindrical main body;
- flange means disposed upon opposite ends of said cylindrical main body and having a plurality of slots defined therein for receiving said plurality of blades therein, said flange means having an axial thickness which is substantially less than the axial length of said cylindrical main body;
- aperture means defined within said plurality of blades;
- and
- adhesive chocking material disposed about said cylindrical main body, interposed between said plurality of blades, and passing through said aperture means of said plurality of blades for bonding said plurality of blades to said cylindrical main body, for bonding said plurality of blades to each other, and for mechanically interlocking said plurality of blades to each other upon solidification of said adhesive chocking material upon said cylindrical main body and between said plurality of blades.
