Embodiment
As can be seen from Fig. 1, Fig. 2, Fig. 3, Fig. 4, the transmission shaft joint coupling that a kind of centre distance is adjustable, it is equipped with connecting head 2, connecting head 6, hinge ball 3, hinge ball 5 and supporting frame 4 between transmission shaft 1, transmission shaft 7.
Described hinge ball 3,5 is balls, and hinge ball surface has two orthogonal circumferential bayonet slots.Hinge ball makes by after the quenching with Subsequent tempering of 40Cr material, ensures enough hardness and intensity, carries out surface ion nitriding treatment after machining, and ensures enough wear resistancies.
Described connecting head 2,6 one end is provided with the U-shaped claw of band arc groove, for being connected with hinge ball.The other end, with cross through hole, is connected with transmission shaft 1,7 by bolt 8,9.Connecting head 2,6 its make by after the quenching with Subsequent tempering of 40Cr material, carry out surface ion nitriding treatment after machining, ensure enough wear resistancies.Transmission shaft 1 described in the utility model is connected with connecting head 2 one end by bolt 9, and described transmission shaft 7 is connected with connecting head 6 one end by bolt 8.
Support frame as described above 4 two ends are respectively equipped with the U-shaped claw of band arc groove, this U-shaped claw is stuck in a circumferential bayonet slot of two hinge balls, supporting frame 4 carries out surface ion nitriding treatment after being machined by making after the quenching with Subsequent tempering of 40Cr material, ensures enough wear resistancies.
A circumferential bayonet slot on the U-shaped claw of described connecting head 2,6 and hinge ball 3,5 is in mating connection; Support frame as described above 4 is between two hinge balls 3,5, its two ends are respectively equipped with the U-shaped claw of band arc groove, the U-shaped claw at support frame as described above two ends is in mating connection with another circumferential bayonet slot on corresponding hinge ball respectively, and supporting frame 4 is connected together between two hinge balls 3,5; By the rotation of the connecting head 2 at intermediate support beam 4 and two ends, connecting head 6 opposite from hinge ball 3 and hinge ball 5, realize the transmission shaft 1 at two ends and transmission shaft 7 translation-angle and centre distance adjustable.Can ensure that the transmission shaft at two ends is angled or freely rotate on two axial directions be parallel to each other.Angular range is between 90-180.
