Lubrication system for podded propulsor bearings

Abstract

The invention provides a lubrication system for podded propulsor bearings. Inlets of input pipelines communicate with an oil tank, and outlets of the input pipelines lead to the positions of the podded propulsor bearings. Inlets of output pipelines lead to the positions of the podded propulsor bearings, and outlets of the output pipeline communicate with the oil tank. Inductive parts of a temperature switch are arranged in the positions of all the podded propulsor bearings in a one-to-one correspondence mode. When the temperature of any one podded propulsor bearing reaches the rated temperature of the temperature switch, a circulating power mechanism inputs lubricating oil in the oil tank to the position of the podded propulsor bearing. The lubrication system has the advantages that aimingat the structure characteristics and part layout type of a podded propulsor, the whole bearing lubrication system adopts a parallel-connection pipeline type, circulating lubrication is conducted on aplurality of support bearings and the propulsor bearings in the podded propulsor correspondingly independently, work temperature of the podded propulsor bearings is controlled through the temperatureswitch, and the bearing operation temperature is controlled effectively.

Description

technical field [0001] The invention relates to a lubricating system, in particular to a lubricating system for pod thruster bearings. Background technique [0002] The power system of the traditional propeller is set outside the propeller body structure, and the power energy is transmitted to the interior of the propeller through the mechanical transmission structure. The interior of the propeller is a closed space filled with lubricating oil. All bearings and transmission structures are Fully immersed in lubricating oil, there is no need to consider the design of a separate lubricating system. At the same time, since the interior of the entire propeller is filled with lubricating oil, although the interior of the propeller is also designed with a forced circulation structure, it does not circulate independently for the bearings, and the cooling effect on the bearings is poor; the lubricating oil inside the entire propeller is only inside the propeller circulation, it is i...

Problems solved by technology

At the same time, since the entire propeller is filled with lubricating oil, although the propeller is also designed with a forced circulation structure, it does not circulate independently for the bearings, and the cooling effect on the bearings is poor; the lubricating oil inside the entire propeller is only inside the propeller circulation, it is impossible to detect whether there is oil leakage, and there is a great hidden danger in protecting the safety of the bearing; and the traditional thruster does not have a device to detect the impurity content of the oil, it is difficult to monitor the wear of the entire bearing, the above four technologies deficiencies, coupled with the fact that pod thrusters are structurally distinct from conventional thrusters
