Description
Technical Field
The utility model relates to a used test device when boats and ships screw carries out the static balance test, specifically speaking are applicable to the horizontal detection device of marine screw static balance test.
Background
Due to casting, machining precision and the like, certain errors inevitably exist in the weight center of gravity of each blade of the marine propeller, so that the whole propeller generates eccentric moment, and the whole propeller is unbalanced. In the running process of the propeller, the centrifugal force generated by the unbalance of the whole propeller directly influences the vibration of the shafting and the ship body, and has adverse influence on the use effect and service life of the bearing and the shaft seal, the shafting transmission efficiency and the noise of the propeller. Therefore, the propeller must be subjected to propeller straightening balance inspection before leaving the factory, an eccentric direction is found out, the propeller straightening is properly adjusted, and the unbalanced moment is controlled within an allowable range.
Therefore, the physical characteristics of the existing test tool are summarized and summarized on the basis of the test requirements of the existing relevant standard specifications, and a brand-new propeller static balance horizontal detection device based on the test process is developed and used for marine propeller inspection.
