The invention discloses a dual-cross hollow shaft joint, which is applied to carrying out low-speed transmission connection to the shaft and the shaft end with small spacing therebetween in mechanism industry, in particular to connecting shaft ends between an output shaft and a driven shaft of a speed reducer; the transmission performance of the shaft joint is more stable than that of the shaft joints such as sleeve type shaft joint, shaft joint with flange disc and stopping port or elastic round pin shaft joint, claw type elastic rubber cushion shaft joint and the like; the shaft joint disclosed by the invention has no noise, and the parts have long service life; the shaft joint has desirable universal performance in dual-cross connecting; with shaft ends can be closer to each other by the hollow structure, so that the occurred space in the field can be reduced. After putting into practice, the shaft joint has desirable practicability.
