A stage of variable-pitch vanes for a turbomachine is disclosed. The vanes include internal pivots engaged in corresponding housings of a sectorized internal ring. Each ring sector includes axial orifices for mounting two pins for the radial retention of the ring sector on the internal pivot of a vane. Each pin includes an immobilization device cooperating by shape coupling with a complementary immobilization device of the other pin in order to rotationally immobilize these pins in the orifices in the ring sectors.

A variable-setting stator blade guidance device of an axial turbomachine is provided. The blade includes an airfoil, a platform and a pivot mounted in the casing of the turbomachine. The device includes a bearing integrated into the platform. In particular, the device includes a bush sandwiched between the platform and the casing, and the integrated bearing is formed between the bush and the platform. In particular, the bush includes a cylindrical surface portion on the side of the platform cooperating with a matching cylindrical surface portion on the platform to form the integrated bearing.

A control lever for the pitch angle of a blade in a turbomachine, said lever having a first end intended to be mounted on a blade pivot so as to rotate it and a second end comprising a cylindrical peg for mounting on a control annulus, this peg being fixed by crimping of one of its ends in an orifice of the second end of the lever and comprising an annular flange to which is applied the second end of the lever, wherein stress distribution means are interposed between the second end of the lever and the crimped end of the peg.
