Marine open water lubricated stern bearing test bench

Abstract

The invention relates to a ship open type water-lubricated tail bearing test bench, which comprises a first base, a driving device, a water tank, a water-lubricated bearing device set and a pressurizing device, wherein the first base is arranged on a workbench; the driving device is fixed on the first base and is sequentially connected with the torque sensor and the transmission shaft; the water tank is arranged on the workbench, one end, away from the torque sensor, of the transmission shaft penetrates through the side wall of the water tank and extends into the water tank, and a sealing device is arranged between the transmission shaft and the side wall of the water tank; the water-lubricated bearing device set is arranged on the shaft section, extending into the water tank, of the transmission shaft; and the pressurizing device comprises a pressurizing bracket arranged on the workbench and a pressurizing assembly which is arranged on the pressurizing bracket and can pressurize the water-lubricated bearing device set, and the pressurizing assembly is arranged on the end surface, away from the workbench, of the water-lubricated bearing device set by means of a pressure sensor. According to the ship open type water-lubricated tail bearing test bench, the influence of the working environment of the open type water-lubricated bearing and the bending of a tail shaft on the performance of the water-lubricated bearing can be simulated more truly, so that the performance of the bearing can be evaluated more truly and effectively.

Description

technical field [0001] The invention relates to the technical field of marine mechanical equipment, in particular to a marine open-type water-lubricated stern bearing test bench. Background technique [0002] The ship stern bearing is a key supporting part of the ship's power propulsion system, and its performance is one of the core issues of the whole power propulsion system, which seriously affects the reliability and safety of the whole ship. Unlike oil-lubricated bearings, water-lubricated bearings use water as a lubricant and are more environmentally friendly. At the same time, the use of water-lubricated bearings does not require the use of lubricating oil, which can effectively reduce the cost of ship navigation, and can also effectively prevent water pollution caused by lubricating oil leakage. [0003] The main pressure on the water-lubricated bearing in the working process comes from the self-weight of the propeller. Since the tail shaft of the ship is in a cantil...
