摘要： A roller segment (14) is held for the purpose of machining a spherical internal bearing surface (10). Its toric external surfaces (18) is supported against two fixed seats (17), immobilized with respect to rotation about an axis (VV') passing through the centers (c) of the profiles of the fixed seats (17) by a third seat (19), which is radially movable. Claws (21) hold the segment against the seats and circumferentially position the segment about the axis (UU') of its toric surface (18).The bearing surface (10) is ground with a slight eccentricity (e) relative to the toric surface, and by grinding a surface suitable for hydrodynamic lubrication is obtained.

摘要： In an articulated transmission joint for automobiles, there is provided a large telescopic range of travel for the joint. A first shaft having a tripod element composed of three radial arms is joined to another shaft with a bowl element. The bowl element is provided with rolling tracks therein. Each arm of the tripod element has two roller segments pivotable thereabout. The roller segments are in rolling contact with the rolling tracks of the bowl element. Each set of roller segments not only has an arrangement for limiting the angular range of movement of the roller segments about their respective arms, but also is provided with an arrangement for limiting the range of telescopic movement of the arms to a maximum extension and a maximum compression position. This arrangement further ensures that the roller segments are at their respective limits of angular movement about each arm when their arm is at an end point of its range of movement in the bowl element. The above-mentioned arrangement is provided by abutments on the roller segments for cooperation in engagement with abutments of the bowl element. The abutments of the bowl element may be formed in the bowl element itself, or may be formed on a clip provided in the bowl element. The joint ensures, in a reliable manner, a large telescopic range of travel.

摘要： A tripod element (18) trasmits by its arms (31) circumferential forces (F) to a female member--or bowl--through cups (20) and rolling needles. On the unloaded side of each arm, a clearance is produced between the arm and the corresponding support surface (24) of the bowl. Springs (16) act on the cups (20, 21) in such manner that this clearance is established between the complementary spherical surfaces of the arm and cup. The reserve of oil which is created therein will act as a shock absorber or damper in the case of reversal of the direction of the torque (C). Use in the elimination of shocks created by the reversal of the load on the joint.

摘要： A setup for use in a press for cold-forming metal parts, such as tripods of universal joints having a central body and radially projecting portions, from a cylindrical billet. A first setup is provided for forming an intermediate workpiece which may then be finished in a second setup. In the first setup the die sectors which make up the die are mounted on rams which are slidably mounted on slotted members between a spaced apart position when the press piston is in its raised position and a clamped together position by means of a toggle mechanism. Punches are provided on the table and the piston which compress the starting billet thereby extruding the metal into channels in each of the die sectors. In the second setup upper and lower die halves are carried respectively by the piston and the table of the press. The die halves have channels adapted to receive the various portions of an intermediate workpiece. Vertical and horizontal punches are provided for finishing various recesses and surfaces of the intermediate workpiece. The die halves are clamped together without working force of the press which may reach 100-200 metric tons.

摘要： An oscillating bearing support for supporting an intermediate shaft of a power transmission with universal joints particularly in motor vehicles. An inner sleeve supports the shaft for rotation therein. An outer support sleeve is fixed to a fixed support. The facing surfaces of the inner and outer sleeves are provided with adjacent circular grooves generally concentric with the axis of the shaft in its rest position. An elastomeric toroidal member is provided wth ribs cooperable with the grooves of the sleeves and concentric with its center line. The toroidal member is fitted on the inner sleeve and compressed between the inner and outer sleeves. Radially projecting portions at the ends of one of the sleeves cooperate with plain cylindrical portions at the ends of the other sleeve for axially retaining the inner sleeve relative to the outer sleeve. The toroidal member may be formed in segments. The grooves in the inner and outer sleeves may be screw threads. The inner and outer sleeves may be formed out of tubular sheet metal blanks.

摘要： The joint comprises a tripod connected to one of the two shafts to be coupled by the joint and defining three trunnions on which three part-spherical rollers are mounted. A second member of the joint is connected to the other shaft and defines three raceways in which the rollers are received. The tripod constitutes a member which is distinct from the shaft associated with the tripod and is connected to this associated shaft by an auxiliary homokinetic coupling. The latter is capable of operating at an angle of displacement which is small relative to the maximum angle of displacement of the two shafts coupled by the joint.

摘要： The joint comprises a first member defining a tripod connected to a first shaft and forming three trunnions. Part-spherical rollers are respectively slidably and rotatably mounted on the trunnions. A second member connected to a second shaft defines three raceways in which the rollers are received. The raceways are each formed by a pair of part-circular sectioned grooves the mean line of which is an arc of a circle centered preferably in the vicinity of the axis of the second shaft. The tripod is rigid with a shaft section which has, in a zone close to the tripod, a substantially triangular cross-sectional shape approximately constituting the envelope of the free edge of the second member when the joint operates with an angular displacement of the first and second shafts close to the maximum possible angle.

摘要： The invention substantially increases the maximum break angle of the joint without increasing its overall size. This is achieved in taking advantage of the planetary movement of the shaft carrying the tripod and the rollers and providing in the free inner edge of the bell recesses the minimum depth of which recesses is calculated in accordance with the amplitude of the aforementioned planetary movement.

摘要： A joint comprises a tripod equipped with three spherical pivots, and a barrel with six cylindrical inner tracks. Intermediate elements comprise a cylindrical surface complementary with the spherical pivot and a surface of circular profile complementary with the circular profile of the tracks. The intermediate elements are blocks, the surface of circular profile of which is a cylindrical surface permanently bearing slidably in the tracks. The joint enables reducing the contact pressures, increasing the telescopic stroke, simplifying the form of the intermediate elements and making it possible to produce them from a material of moderate hardness.

摘要： Arms (2) of a tripod element (1) are in force-transmitting relation in the circumferential direction and in mobile relation in the axial direction, with rolling tracks (9) provided longitudinally inside a bowl (10), through the medium of roller segments (6,6a, 6b). The latter have a toric outer surface (8) in rolling contact with the tracks (9) which have a corresponding transverse radius of curvature, and an inner spherical surface (3) which is in ball-joint relation to spherical regions (3) of the arms (2). When the joint operates in contraction-extension, each roller segment (6) slides around the spherical regions (3) and rolls in the tracks (9) until, in an extreme position, the two roller segments (6a, 6b) associated with each arm abut against each other by their circumferential ends (14). Utilized for reducing the number of component parts of the joint and eliminating friction between points whose relative paths have turning back points.
