US 20080167150 A1Abstract
Tensioning roller device including a non-rotating part about which there is rotationally mounted a pulley-forming rotating assembly designed to collaborate with a belt or a chain and a rolling bearing positioned between the non-rotating part and the pulley and including a rotating ring, a non-rotating ring and rolling elements, the pulley including a rigid rim including a first part fixed to the rotating ring of the bearing and a second part that can move with respect to the first part under the action of an elastic element, and an expandable sleeve of annular overall shape designed to be in contact with the belt or the chain, the diameter of the expandable sleeve varying according to how hard it is pressed by the second part.
1. Tensioning roller device comprising a non-rotating part about which there is rotationally mounted a pulley-forming rotating assembly designed to collaborate with a belt or a chain and a rolling bearing positioned between the non-rotating part and the pulley and comprising a rotating ring, a non-rotating ring and rolling elements, wherein the pulley comprises a rigid rim comprising a first part fixed to the rotating ring of the bearing and a second part that can move with respect to the first part under the action of an elastic element, and an expandable sleeve of annular overall shape designed to be in contact with the belt or the chain, the diameter of the expandable sleeve varying according to how hard it is pressed by the second part.
2. Device according to claim 1, wherein the expandable sleeve can be expanded radially.
3. Device according to claim 1, wherein the sleeve has frustoconical lateral faces to match the shape of the first and second parts.
4. Device according to claim 1, wherein the sleeve is symmetric with respect to a radial plane.
5. Device according to claim 1, wherein the sleeve has an axial bore to match the shape of the first part.
6. Device according to claim 1, wherein the sleeve has substantially radial lateral faces to match the shape of the first and second parts.
7. Device according to claim 1, wherein the sleeve has a frustoconical interior face to match the shape of the first part.
8. Device according to claim 1, wherein the second part is in the form of a cup mounted with the ability to move in axial translation on the first part.
9. Device according to claim 1, wherein the elastic element comprises a spring positioned between the second part and a bearing surface secured to the first part.
10. Device according to claim 1, wherein the expandable sleeve is in one piece. Description
The rotating part 3 of the automatic tensioning roller includes a rim 18 and an expandable sleeve 19, of annular overall shape and positioned in an annular housing that is open to the outside and formed in the rim 18. The expandable sleeve 19 has an annular exterior surface 19 adesigned to come into contact with the belt 5. The expanding sleeve 19 also has a cylindrical bore 19 b and two slightly frustoconical lateral surfaces 19 c and 19 d. The rim 18 includes a main part 20 provided with a bore in which the outer ring 11 of the rolling bearing 4 is pushed. The main part 20 includes a flange 20 a of radial overall shape directed outwards on the same side as the head of the screw 7, a stepped exterior surface with a large-diameter surface 20 b, a shoulder 20 c and a small-diameter surface 20 d at the same end as the support 9. The face of the flange 20 a that is adjacent to the large-diameter surface 20 b is slightly frustoconical to match the shape of the lateral surface 19 c of the expanding sleeve. The large-diameter surface 20 b is axial and in contact with the bore 19 b of the expandable sleeve 19.
