As for the practicality of this, it would work better if the rollers were grooved with the bands running in the grooves so that you would not have them between the bearing surfaces. |
|
| |
That was exactly what I was thinking. To eliminate slipping
though, the groove diameter to roller diameter ratio would
have to be the
same for both sets of rollers so there would be shallow
grooves in the spacing rollers and deeper grooves in the
main ones. |
|
| |
that is the highest surface area bearing design I have ever seen. You must be thinking of very low speed operation in a perfectly clean environment with self lubricating materials. |
|
| |
The intention is to suspend the spacing rollers in the gaps between the bearing rollers ? |
|
| |
Gould this not be achieved by having two rings on each side of the bearing with matching sets of holes into which the tips of the spacing rollers extended ? Perhaps the spacer rollers could have conical ends and seat in depressions in the annular supports. |
|
| |
This would have short, load-bearing rollers within the race, and longer, thinner spacer rollers extending beyond the race. |
|
| |
Lubrication is still going to be needed ... |

Category suggestion: "Product: Engine" ? |

Suggested new subcategory: "Product:Engine:Component" or "Product:Mechanical" |

Wow, a semi-patentable idea on the bakery... |
|
| |
I experimented with a design like that and found that the
ring could drift along with all of it's spacing rollers to one
side. Though I just had another Idea. the outer raceway
could be extended around and inwards at it's ends so as
to
support the spacer rollers. The spacer rollers are ratating
counter to the main load bearing ones their
interior sides would rest on the outer raceway preventing
inwards movement while a ring or band prevents
outwards movement. the spacing
rollers would have to have a reduced diameter where
they are supported by the outer raceway and a groove
for the ring to sit in but it should be doable. It would also
be extremely difficult if not impossible to assemble but
this is halfbakery. This kind of setup might even work
with tapered roller bearings, something a band
constrained design would be hard
pressed to do. |
