Abstract
The quality of the lubrication of an inter-shaft bearing, particularly one with counter-rotational bushes, is improved by the presence of an obstacle on the outer bush which allows an adjustment in the quantity of oil present on the outer roll track. In particular, the drying of the roll track under the effect of the repeated running of the runners is compensated for by organizing a mandatory axial circulation.
