Abstract

The invention provides a marine universal coupling which comprises a torque transmission shaft and a torque transmission shaft sleeve. Sliding grooves are formed in the inner wall of the torque transmission shaft sleeve in the axial direction, and a plurality of torque transmission assemblies are arranged between the torque transmission shaft and the sliding grooves of the torque transmission shaft sleeve and connected with the torque transmission shaft through transition pieces. According to the marine universal coupling, the torque transmission assemblies and the transition pieces are arranged between the torque transmission shaft and the sliding grooves, so that the contact stress of bearings has the self-balancing capacity, the load uniformity of the bearings is improved, the contact strength of the bearings can be met under the condition of large torque, and the technical problem that in the prior art, a torque transmission bearing telescopic universal coupling is poor in torque transmission capacity is solved.

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 elastic vibration isolation technology for diesel engines and gearboxes, universal couplings have become one of the key equipment in ship power systems. Its main function is to meet the needs of shafting with angular transmission and axial displacement compensation. Among them, the axial displacement compensation mechanism is a key component of the universal joint, which mainly performs the function of axial displacement compensation. [0003] The traditional axial displacement compensation mechanism of universal joint mostly adopts the combination of spline shaft and spline sleeve, which transmits shafting torque through spline pair and compensates axial displacement through sliding friction. This solution has the advantage of greater torque transmission capacity, but th...
