Thrust bearing device with compact structure

Abstract

The invention relates to the technical field of thrust bearings of main shaft systems of submersible vehicles, and particularly discloses a thrust bearing device with a compact structure. A forward running end and a reverse running end adopt an asymmetric design form, an oil inlet and outlet pipe is arranged on a transition surface, and a supporting bearing bush and a forward running lantern ring adopt a conformal design; reverse running thrust blocks, forward running thrust blocks and the bush surface of the supporting bearing bush are made of a large-ratio shaft bush material, and the shell is of a high-strength steel plate welding structure, so that the overall weight, occupied size and the like of the thrust bearing can be greatly reduced, the mounting space of equipment on a submersible vehicle is saved, and the occupation of the overall weight resource of the submersible vehicle is reduced; and besides, vibration reduction cylinders are closely arranged behind an even number of the forward running thrust blocks which are evenly distributed in the circumferential direction, the vibration reduction cylinders are communicated through hydraulic pipelines and are connected with an energy accumulator structure to form a communicating device, so that the forward running thrust blocks in the circumferential direction are equal in stress, the stress can be balanced, and the situation that a single thrust block is excessively stressed and burnt due to installation and machining errors is avoided.

Description

technical field [0001] The invention relates to a thrust bearing of a submersible main shaft system, in particular to a thrust bearing device with a compact structure. Background technique [0002] The thrust bearing is one of the important equipment of the submersible shaft system. It acts as a thrust transmission hub to transmit the thrust or pull generated by the propeller to the hull to push the hull forward or backward. In addition to propeller thrust, the thrust bearing of the submersible also bears the hydrostatic thrust brought about by the seawater pressure of the shafting penetrating part. Increased thrust bearing design size and weight. [0003] The thrust bearing of the shafting of the submersible is large in size and weight, occupying the core space of the propulsion cabin, making it difficult to arrange equipment in the cabin. With the demand for large depths in the future, the thrust load of the propulsion system will increase significantly, and the structur...
