Wheel hub assembly

A wheel hub assembly comprising:

• a hub shell having opposite first and second ends, a through bore extending through said first and second ends, and first and second flanges extending outward from said hub shell for interconnecting said hub shell to a plurality of spokes;
• said through bore, at opposite ends thereof, being tapered from wide to narrow in an inward direction along said axis of said hub shell;
• first and second bearing cups each having opposite first and second sides, a frustoconical-shaped body extending between said first and second sides, a bearing seat bore formed through said first side, and an axle bore formed through said second side and connecting with said bearing seat bore, said frustoconical-shaped body tapering from wide to narrow in a direction from said first side to said second side, wherein said taper of said frustoconical-shaped body corresponds to said taper of said through bore at one of said opposite ends of said through bore such that said frustoconical-shaped body is disposed within said through bore at the respective end thereof and movable in a direction along said axis;
• a first bearing removably seated within said bearing seat bore of said first bearing cup;
• a second bearing removably seated within said bearing seat bore of said second bearing cup;
• an axle extending along said axis of said hub shell and through and rotatably engaged with said first and second bearings;
• a wave spring positioned on one end of said axle and being retained in place on said axle such that a biasing force is exerted by said first wave spring upon said first bearing in a direction along said axis of said hub shell;
• and
• wherein an opposite end of said axle has a bearing engaging shoulder, said bearing engaging shoulder pressing upon said second bearing by said biasing force provided by said wave spring.

A wheel hub assembly comprising:

• a hub shell having opposite first and second ends, a through bore extending through said first and second ends, and first and second flanges extending radially from the axis of said hub shell for interconnecting said hub shell to a plurality of spokes;
• said through bore, at opposite ends thereof, being tapered from wide to narrow in an inward direction along said axis of said hub shell;
• first and second bearing cups each having opposite first and second sides, a frustoconical-shaped body extending between said first and second sides, a bearing seat bore formed through said first side, and an axle bore formed through said second side and connecting with said bearing seat bore, said frustoconical-shaped body tapering from wide to narrow in a direction from side first side to said second side, wherein said taper of said frustoconical-shaped body corresponds to said taper of said through bore at one of said opposite ends of said through bore such that said frustoconical-shaped body is removably seated within said through bore at the respective end thereof;
• a first angular contact bearing removably seated within said bearing seat bore of said first bearing cup;
• a second angular bearing removably seated within said bearing seat bore of said second bearing cup;
• an axle extending along said axis of said hub shell and through and rotatably engaged with said first and second angular contact bearings;
• a first wave spring positioned on one end of said axle and being retained in place on said axle such that a biasing force is exerted by said first wave spring upon said first bearing in a direction along said axis of said hub shell;
• and
• a second wave spring positioned on an end of said axle opposite of said first wave spring and being retained in place on said axle such that a biasing force is exerted by said second wave spring upon said second bearing in a direction along said axis of said hub shell.
