A pulley comprising a wheel or sheave (1) having a central recess (2) and a channel (3); and at least one fastening cable (4) designed for transmitting the force from the sheave (1) to a fastening point, the cable passing transversely to the sheave (1) through the central recess (2); and which incorporates at least one low-friction bushing (6) that is housed between the fastening cable (4) and the sheave (1).
Claims6
A pulley comprising a sheave (1) without roller bearings that incorporates a central recess (2) and a channel (3);
- at least one fastening cable (4) configured to transmit the force from the sheave (1) to a fastening point passing transversely to the sheave (1) through the central recess (2);
- and at least one body having an aperture arranged to guide the fastening cable (4) through the central recess (2);
- wherein said pulley further comprises at least one low-friction bushing (6) which is housed between the fastening cable (4) and the sheave (1);
- and wherein the low-friction bushing (6) comprises two opposite sides, wherein a first side is in direct contact with the fastening cable (4) and a second opposite side is in direct contact with the sheave (1) through the central recess (2) in such a way that the low-friction bushing (6) is in a compression state between the fastening cable (4) and the sheave (1) when loaded.
