Abstract
Filtering pullies with a hub adapted to be fixed to a rotating shaft, a crown mounted coaxially and rotationally free on the hub, at least one elastic group arranged circumferentially with respect to the hub and the crown and interposed, each, between a pair of first elements integral with the hub and between a pair of second elements integral with the crown are disclosed. The pulley has a dust protection system configured to isolate the at least one elastic group with respect to the external environment and to provide an axial force generating a damping to the movement between the hub and the crown.
Claims19
Filtering pulley comprising:
- a hub adapted to be fixed to a shaft rotating around an axis (A),
- a crown mounted coaxially and rotationally free on said hub, the crown comprising a closing element;
- at least one elastic group arranged circumferentially with respect to said hub and said crown, and interposed, each, between a pair of first elements of an actuator integral with said hub and between a pair of second elements integral with said crown,
- a dynamic damper, and
- a dust protection system configured to isolate said at least one elastic group with respect to the external environment and to provide an axial force generating a damping to the movement between said hub and said crown, wherein said dust protection system comprises:
- a sealing element in contact with the covering element of the crown;
- and
- an elastic element comprising a first end pinched between the dynamic damper and the actuator of said hub and a second end cooperating with said sealing element and biased into engagement with the covering element of the crown.

- at least one elastic group arranged circumferentially with respect to the hub and the crown, and interposed, each, between a pair of first elements integral with the hub and between a pair of second elements integral with the crown,
- a dust protection system comprising an elastic element and a sealing element, the elastic element having a first end connected to the hub and a second end cooperating with the sealing element, and the sealing element cooperating in contact with the pair of second elements integral with the crown, wherein the dust protection system is configured to isolate the at least one elastic group with respect to the external environment and to provide an axial force generating damping to the movement between the hub and the crown;
- wherein the sealing element comprises a first sealing element made of plastic and a second sealing element made of rubber.
