Embodiment 1

[0028] The universal joint of this embodiment is used to connect the driving shaft and the driven shaft, and transmit the torque from the driving shaft to the driven shaft.

[0029] Such as figure 1 As shown, the universal joint of this embodiment includes a first shaft coupling 10, a second shaft coupling 20, and a first shaft coupling that is rotationally connected to the first shaft coupling 10 and the second shaft coupling 20, respectively. 30. One end of the first shaft coupling 30 in the length direction is rotationally connected to the first shaft coupling 10 through a first rotating shaft 40 . The other end in the length direction of the first shaft coupling 30 is rotationally connected to the second shaft coupling 20 via a second rotating shaft 50 . The first rotating shaft 40 and the second rotating shaft 50 are respectively perpendicular to the length direction of the first coupling 30 , and the first rotating shaft 40 and the second rotating shaft 50 are perpendi...

The other end in the length direction of the second coupling 81 is rotatably connected to one end of the mandrel 100 through the fourth rotating shaft 84 . The third rotat...

Embodiment 3

[0055] Such as figure 2 As shown, the difference from the second embodiment above is that the second universal joint 90 of this embodiment includes a third coupling joint 91 and a fourth coupling member 92 . One end of the third shaft coupling 91 in the length direction is rotationally connected to the fourth shaft coupling 92 through a fifth rotating shaft 93 . The other end in the length direction of the third coupling 91 is rotatably connected to one end of the spindle 100 through the sixth rotating shaft 94 . The fifth rotating shaft 93 and the sixth rotating shaft 94 are respectively perpendicular to the length direction of the third coupling 91 , and the fifth rotating shaft 93 and the sixth rotating shaft 94 are perpendicular to each other.

[0056] The structure of the third coupling 91 in this embodiment is the same as that of the first coupling 30 in the first embodiment. The structure of the fourth shaft coupling 92 is the same as that of the first shaft coupling...

Abstract

The invention relates to a universal coupler. The coupler comprises a first coupling piece, a second coupling piece and a first coupling, wherein the first coupling is rotatably connected with the first coupling piece and the second coupling piece. One end, in the length direction, of the first coupling is rotatably connected with the first coupling piece through a first rotary shaft, and the other end, in the length direction, of the first coupling is rotatably connected with the second coupling piece through a second rotary shaft; and the first rotary shaft and the second rotary shaft are perpendicular to the length direction of the first coupling, and the first rotary shaft is perpendicular to the second rotary shaft. According to the embodiment of the universal coupler, a reasonable structural design is adopted, the machining and manufacturing difficulty of key parts is lowered, the cost is low, and therefore the whole machining and manufacturing difficulty and the cost of the universal coupler are reduced.

Description

technical field [0001] The invention relates to the technical field of transmission equipment, in particular to a universal joint. Background technique [0002] The universal coupling uses the characteristics of its mechanism to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque mechanical parts. The universal coupling can make two transmission shafts with different shafts (that is, the axes of the two transmission shafts have an angle) realize the continuous rotation of the two transmission shafts connected, and reliably transmit torque and motion. The biggest feature of the universal coupling is: its structure has a large angle and direction compensation capability, compact structure, and high transmission efficiency. In the high-speed and heavy-duty power transmission, the universal coupling also has the function of buffering, damping and improving the dynamic performance of the shafting. The unive...
