Abstract
A non-rotatable shaft/hub connection, providing a shaft having a tapered end and a bore, the tapered end having at least two angled faces; a hub having a tapered opening and an aperture, wherein the tapered opening is configured to receive the tapered end, the tapered opening provides at least two tapered portions. The non-rotatable shaft/hub connection provides an anti-backlash shaft/hub interface, having a shaft adapted to be rotatably driven about an axis of rotation, the shaft having a tapered end providing a tapered, double-D configuration; and a hub, having an opening configured to receive the double-D configuration of the tapered end.
Claims16
A non-rotatable shaft/hub connection, comprising:
- a cylindrical shaft portion having a tapered end and a bore extending along a central axis and throughout the shaft portion;
- and
- a hub portion having an aperture and a tapered opening configured to receive the tapered end, wherein the hub portion provides a tapered, double-D configuration, and
- wherein the bore of the shaft portion and the aperture of the hub portion are axially aligned such that a threaded fastener can pass through the bore of the shaft body and engage the aperture to axially clamp together the shaft portion and the hub portion.
A non-rotatable shaft/hub connection, comprising:
- a shaft having a tapered end and a bore, the tapered end providing at least two angled faces, wherein the tapered end comprises a tapered, double-D configuration;
- and
- a hub having a tapered opening and an aperture, wherein the tapered opening is configured to receive the tapered end, the tapered opening providing at least two tapered portions;
- and
- a fastener extending through the bore and received by the aperture to axially clamp together the shaft and the hub.
An anti-backlash shaft/hub interface, comprising:
- a shaft adapted to be rotatably driven about an axis of rotation, the shaft having a tapered end providing a tapered, double-D configuration;
- and
- a hub, having a two prong opening configured to receive the double-D configuration of the tapered end,
- wherein the shaft further comprises a bore, and the hub further comprises an aperture, and wherein a fastener extends through the bore and is received by the aperture to clamp together the shaft and the hub;
- and
- a collar encompassing an exterior of the hub two prong opening.
