Definitions
- the present invention relates to a coupling card for a double cardan joint. More specifically, the present invention relates to a coupling yoke of a double cardan joint in which a driving side yoke and a driven side yoke are connected at both ends in the axial direction and a driving force from the driving side yoke is transmitted to the driven side yoke.
- a so-called split type is known that includes an enclosing means for enclosing the central portion in the axial direction of both bridge members, and a fastening means for fastening the bridge members and the enclosing means (see, for example, Patent Document 1). ).
- a pair of flange portions having bearing holes for rotatably mounting one shaft portion of the cross shaft and facing each other are respectively axially extending from both axial ends of the base portion.
- This integrated coupling yoke is formed by casting or forging, and as in the split coupling yoke described in Patent Document 1, the bridge member and the surrounding means are assembled and then assembled by fastening means. Since it is unnecessary, it is advantageous in terms of work man-hours. Moreover, since it is an integrated type, it is excellent in terms of rigidity.
- the base portion on which the flange portion protrudes is constituted by a block-like thick portion, but the drive side yoke and the driven side yoke connected by the coupling yoke are slightly different.
- the weight of the entire coupling yoke increases accordingly. As the weight increases, the moment of inertia of the coupling yoke increases, and the energy loss during transmission of the driving force from the driving side yoke to the driven side yoke increases.

- the thickened portion that connects the bearing holes of the flange portion that are located on each other and exhibits an X shape when viewed from the axial direction of the other shaft portion of the cross shaft, and the adjacent thick portion that exhibits the X shape It consists of a thinned portion between the thick-walled parts.

- the double cardan joint 1 connects a drive side yoke and a driven side yoke (not shown) via a coupling yoke 2, a drive side cross shaft 3 and a driven side cross shaft 4 so as to be bent.
- the coupling yoke 2 includes a central base portion 11 and a pair of flange portions provided at both axial ends of the base portion 11 (both left and right ends in FIG. 4). 12 and 13.
- the drive-side flange portion 12 has a bearing hole 14 for rotatably mounting one shaft portion 3a of the two orthogonal shaft portions of the drive-side cross shaft 3 so as to face each other.
- the base 11 protrudes in the axial direction from both axial ends.
- the shaft portion 3 a is attached to the bearing hole 14 via a cylindrical bearing 16.

- a driven-side yoke mounting member 8 for mounting the driven-side yoke is rotatably attached to the other shaft portion 4 b of the driven-side cross shaft 4 via a cylindrical bearing 9.
- the base 11 has a substantially rectangular shape when viewed from the front (front viewed from the axial direction of the other shaft 3b, 4b of the cross shaft 3, 4).
- Thickened portion 18 having an X-shape when viewed from the axial direction of the other shaft portions 3b and 4b of 3, 4 and a thickness removal between adjacent thick portions 18a of the thick-walled portion 18 having the X-shape It is comprised with the part 19.
- FIG. The thick wall portion 18 connects the bearing holes 14 and 15 of the flange portions 12 and 13 located on the diagonal line.
- the thick portion 18 in the present embodiment has an X shape as a whole. More specifically, the flange portions 12 and 13 are formed from a central rectangular portion 18b and four corners of the rectangular portion 18b. It consists of four thick-walled parts 18a each extending to the root part of the. A portion between adjacent thick portions 18 a is a thinned portion 19.
- the thinning portions 19a located between the flange portions 12 and 13 adjacent to each other along the axial direction of the base portion 11 are the other shaft portions 3b and 4b of the cross shafts 3 and 4.
- the thin portion is substantially flat and is thinned in the axial direction.
- the remaining two thinned portions 19b are shaped such that they are suddenly thinned from the central rectangular portion 18b toward the outside in the axial direction, and finally become zero thickness.
- the thickness of the thick portion 18 (the size in the direction perpendicular to the paper surface in FIG. 4) and the width W of the thick portion 18a depend on the design torque acting on the coupling yoke 2 and the axial direction between the cross shafts 3 and 4. It can be appropriately selected according to the separation distance.
- the rigidity of the coupling yoke 2 can be ensured by configuring the base portion 11 with the thick portion 18 and the thinned portion 19 having the X shape. That is, the load applied to the coupling yoke 2 that transmits the rotational force acts on the coupling yoke 2 from the bearing holes 14 and 15 that support the shaft portions of the cross shafts 3 and 4, and more specifically, the coupling yoke. With respect to the bearing holes 14 and 15 of the four flange portions 12 and 13 of No. 2, they act substantially along a line connecting the bearing holes 14 and 15 of the flange portions 12 and 13 located on the diagonal line. Thus, by providing the X-shaped thick portion 18 along the load acting direction with respect to the load acting in the X-shape, the proof stress against the load can be increased. In other words, torsional rigidity can be ensured.
- the thinned portion 19a located between the flange portions 12 and 13 adjacent to each other along the axial direction of the base portion 11 is used as the shaft of the other shaft portions 3b and 4b of the cross shafts 3 and 4. Since the substantially thin thin portion is thinned in the core direction, the bearing holes 14 and 15 of the flange portions 12 and 13 can be easily formed by fixing the flat thin portion with a jig. it can.

- the coupling yoke 22 is shown in FIGS. 2 to 10 in that the thinning portions 39 located between the flange portions 12 and 13 adjacent to each other along the axial direction of the base portion 31 are substantially thinned. This is different from the coupling yoke 2 to be manufactured. Accordingly, common elements or configurations are denoted by the same reference numerals, and descriptions thereof are omitted.
- the thinning portions 39 positioned between the flange portions 12 and 13 adjacent to each other along the axial direction of the base portion 31 are substantially thinned. It is possible to further reduce the weight of the coupling yoke 22 while ensuring rigidity.
- the coupling yoke has a pair of bearing holes for rotatably mounting one of the two orthogonal shaft portions of the cross shaft and facing each other.
