Description

Technical Field

[0001] The present application relates to the technical field of guide sleeves, and in particular to a thrust shaft guide sleeve. Background Art

[0002] The thrust shaft is a separate shaft section in the shaft system that is used to bear and transmit axial force and transmit it to the hull through the thrust bearing. The thrust shaft usually needs to be used in conjunction with a guide sleeve. When the thrust shaft and the thrust shaft guide sleeve are used in conjunction, when the two move relative to each other, a large friction force will be generated, and a large amount of heat will be generated. Therefore, the heat dissipation effect of the guide sleeve determines the quality of the guide sleeve.

[0003] When the thrust shaft moves relative to the thrust shaft guide sleeve, the high temperature generated will cause accelerated wear between the thrust shaft and the thrust shaft guide sleeve. The thrust shaft guide sleeve in the prior art generally dissipates the heat inside the thrust shaft guide sleeve by opening ventilation holes inside the thrust shaft guide sleeve. The heat dissipation effect is single, resulting in that the improvement of the heat dissipation effect is not very obvious, which is not conducive to practical application and operation.
