Embodiment Construction

[0004] Set the name of the ten-byte bracket connected with the universal joint as the shaft fork; the end of the two shaft forks connected to the shaft head is modified to have the same structure as the one connected to the ten-byte end, this is named double-headed shaft fork; each The axis lines of the two pairs of holes of the double-headed axle fork are parallel and intersect with the axis line of the double-headed axle fork; drill a through hole for each of the shaft heads and vertical axis lines of the two shafts originally equipped with the axle fork, and use The two shaft pins respectively connect the double-headed shaft fork pins on the shaft heads of the above two through holes, and the ten bytes are still connected as before. The connection sequence: shaft head, double-headed shaft fork, ten bytes, double-headed shaft Forks, shaft heads, and the axis lines of the two shafts and two double-headed shaft forks are required to be in the same line, and the extension lines o...

Abstract

The invention relates to a universal joint for connecting two shafts to be capable of doing shaft axis extension line parallel and non-concentric transmission. The universal joint can connect the two shafts to do shaft axis parallel but non-concentric synchronous transmission. Therefore, the requirement of the universal joint for concentricity is not strictly thinner than hair any more. By means of the universal joint, noise is reduced, bouncing is eliminated, the manufacturing difficulty is greatly reduced, and especially the manufacturing difficulty of assembly of extra-large crankshafts with the mass being 100 t or above is reduced. A main journal can be thickened all the time to be as large as the motion track of a crankshaft arm; friction resistance increased by thickening is reduced by replacing a bearing bush with a roller bearing, and an inner ring of the bearing is directly machined on the main journal; and compared with the bearing bush, the bearing is easy to start and saves energy. According to the universal joint, assembly is facilitated, besides, the most special performance is to eliminate the least bit errors of manufacturing, and therefore the longitudinal size of the position can be quite short, and shaft pins can be inserted by perforating the surface of the journal. In addition, the level of making concentricity is already quite high, the universal joint almost does not need to work, and therefore the fit clearance of the shaft pins can be almost close to 0.

Description

Technical field [0001] Used for the connection of the combined crankshaft, the combined crankshaft has applied for an invention patent, patent number 201710091211.4. Background technique [0002] The existing universal joints cannot satisfy the real universal adjustment. Summary of the invention [0003] A rotary joint is added between the universal joint and the two connected shaft heads. detailed description [0004] Set the name of the ten-byte bracket connected with the universal joint as the shaft fork; the end of the two shaft forks connected to the shaft head is modified to have the same structure as the one connected to the ten-byte end, this is named double-headed shaft fork; each The axis lines of the two pairs of holes of the double-headed axle fork are parallel and intersect with the axis line of the double-headed axle fork; drill a through hole for each of the shaft heads and vertical axis lines of the two shafts originally equipped with the axle fork, and use The tw...
