摘要:
The wide-angle constant velocity joint (100) comprises: a central core (101) forming respective inner yokes (24, 25) for connection and in which there is housed a guide disc (11); and outer yokes (103, 105). The central core (101) forms a lubricant reservoir (1) in communication with an annular seat (7) in which the guide disc (11) is slidingly received.

The joint comprises two spiders 18 and a central core 16 forming a housing 24 for the sliding movement - in a transverse plane - of a basically discoidal constraint member 20 forming the seats 20A for the spherical end heads 10C, 14C of the two forks. The constraint member 20 moves about inside said housing 24. Between each of said two surfaces 24A, 24B and the opposing face of said constraint member 20, an elastic laminar ring 40 shaped like a Belleville washer is interposed, its annular edges being in continuous annular contact with said surface 24A or 24B and with said opposing face of the constraint member 20.
摘要:
Wide-angle constant velocity joint, with two yokes (10, 14), two cross journals (18) and a central core (16) forming a sliding housing (24) for a securing member (20) for the ball ends (10B, 14B) of the two yokes; the terminal edges (36C, 36B; 38C; 38B) of protective bellows means (36; 38), which delimit a space which surrounds the joint and can contain liquid lubricant for oil-bath lubrication, are tightly engaged with the central core (16) and with the base (10A; 14A) of each of the two yokes (10, 14).
摘要:
A torque limiting coupling has recesses (5) parallel to the axis of rotation on the inner surface (1C) of an outer member (1), and an equal number of keys (20) slidable radially in seats (18) in an inner member (3) and elastically biased towards the recesses (5). In order to ensure re-engagement of the keys (20) in the recesses (5) in a single relative angular position of the inner and outer members (1, 3), each recess contains at least one peg (41) flush with the inner surface (1C) of the outer member (1), and each key (20) contains a through notch (43), the axial position of each peg (41) and notch (43) of the corresponding recess (5) and key (20) are unique.
摘要:
The tubular member for telescopic propeller shafts has a cross-sectional profile with four projections 1, 1 and 3, 3 and respective longitudinal channels 5, 5 and 7, 7; each of the projections has symmetrical outwardly converging walls; and the plane of symmetry X-X of two opposing projections 1, 1 forms an angle of 85° and an angle of 95° with the plane of symmetry Y-Y of the other two opposing projections 3, 3.
摘要:
A system is described comprising a mixer-wagon and a mechanical power transmission unit (100) to actuate the rotating members of the mixer-wagon; the transmission unit comprises a box (20), a fist shaft (1) accessible from the outside of the box (20) and a second shaft (4) accessible from the outside of the box (20). The first shaft (1) and the second shaft (4) are coupled by means of an epicyclical gear train (19).
摘要:
The second boot that protects parts adjacent to a fixed box from which there projects a rotating hub that is to be connected to a driveline (with the possible presence of a friction clutch or of a torque limiting means) comprises - attached to the fixed box (1) - a disc (11) with a peripheral edge (11A) for engagement and fastening; and a sleeve (17) that can be engaged inside the edge (11A-11B) of said disc (11), with fastening clips (22) capable of being clipped to and unclipped from said edge (11A-11B). Said sleeve (17) may include protective layers around the parts which it encloses.
