Now you have up to ten-times more success if you take my patented
.
return-rollers with special rubberrings(Priorität-Gebr.-Musterschutz # 20 2009 000 178.
My reflection is, to find out why the rollers you can not use for a long time.
.
(reason A)
.
The first reason is that "ALL MUST BEE CHEEPER!" and than the quality of the
.
rubber ring is also less! (in the moment for odinary rings with 160mm³ consume)
.
(reason B)
.
You can find that a twice-conic roller will lead the belt, with no control, to the left
.
and the right side, because you have twice-anti - conic roller.
.
The cause you find in the rule, that the consume of the rings in the middle is much
.
more higher, as the diameter of the consumed ring is smaller.
.
(5mm less–Ø means always a friction of more than 30 mm in every rotation!)
.
Do you want to eliminate this mistakes, than you will find my idea:
.
a) What can we do that the consume of the rings in the middle is less?
.
b) What can we do that the rubber belt will not turn to the side?
.
For this problems my
.
"TRIPPLE-ROLLERS" are the best!
.
.
RESULT a) you choose for the dirty area rings in a better qualitiy! (In Germany I use
.
rubberrings with max consume (or better) than 60mm³,
.
(or something next better in polyurethane!)
.
In this case you can get a longer life for such rollers with ca. 100 %!
RESULT b) you choose a roller with 3 idlers on one axle; I call it
.
"TRIPPLE-Underbelt-Roller",
.
I take it, because the roller in the middle can turn with an other speed if the rings are
.
a little bit consumed. So you have a regulation of the rubber belt and not more
.
a friction between the rings with the smaller diameter of it.
.
We don’t also have not more longer an anti-conic-roller!
.
(In this case the belt will run very well straight on)
.
With this two factors together we can expect that
.
in RESULT a+b) the life for this rollers is further on ten times longer! and the belt will
.
hold much longer and you have less service to control the running belt straight on,
.
LAST not LEAST you can get this rollers with the same measures than the old rollers
.
in your construction and you must not change anything!
.
My special-Rollers guide your belt always to the centre!
