Abstract
This invention concerns an isostatic device (10) to provide rolling and support with revolvable bodies which comprises an inner ring (12), an outer ring (11), a cage (13) and three revolvable bodies (14) fitted substantially at angles of one hundred and twenty degrees from each other, in which device (10) the revolvable bodies (14) are kept in position by the cage (13), the mean circumference of which is offset in relation to the median circumference of rolling of the revolvable bodies (14), and one ring is substantially stiff and the other ring is resilient with a suitable degree of contact with the revolvable bodies (14) so that, after being fitted, the resilient ring tends to take up a three-lobed conformation, thus providing a pre-set pre-load for the revolvable bodies (14). The invention also concerns a device which has adjustable braking means and which can be used as a rotatable ring.
