Abstract

The invention provides a marine universal coupling, which includes a torsion transmission shaft and a torsion transmission sleeve, the inner wall of the torsion transmission sleeve is provided with a chute along the axial direction, and a plurality of torsion transmission shafts The assembly is arranged between the torsion transmission shaft and each sliding slot of the torsion transmission sleeve, and is connected to the torsion transmission shaft through a transition piece. In the marine universal joint of the present invention, a plurality of torsion transmission assemblies and transition pieces are arranged between the torsion transmission shaft and each chute, so that the contact stress of the bearing has self-balancing ability, and the bearing capacity is improved. Excellent load equalization, which can meet the contact strength of the bearing under the condition of large torque, and solve the technical problem of weak torsion transmission capacity of the telescopic universal joint coupling of the torsion transmission bearing in the prior art.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission devices, in particular to a marine universal joint. Background technique [0002] With the wide application of the elastic vibration isolation technology of diesel engines and gearboxes, the universal joint has become one of the key equipment in the marine power system, and its main function is to meet the needs of shaft belt angle transmission and axial displacement compensation. Among them, the axial displacement compensation mechanism is the key component of the universal coupling, which mainly plays the function of axial displacement compensation. [0003] Most of the traditional universal coupling axial displacement compensation mechanism adopts the combination of spline shaft and spline sleeve, transmits the shafting torque through the spline pair, and compensates the axial displacement through sliding friction. This solution has the advantage of a large torque transmission ...
