Problems solved by technology

However, the signal cable may get caught on the rotating crankshaft, so the cable makes the measurement inconvenient
[0008] In addition, conventional digital deviation sensors (such as LVDT (Linear Variable Differential Transformer) sensors or magnetic sensors that use a sensor head to read the deviation) are larger than 100mm (100mm is the size of the shaft shaft of a medium-speed marine engine) The typical length of the opposite ends), so such a traditional digital deviation sensor cannot be used for the deviation measurement of the crankshaft

Abstract

The present invention relates to a measuring system for crank shaft deflection in a marine engine. The measuring system for crank shaft deflection in accordance with the present invention is characterized by comprising a deflection measuring device and a dedicated display device, and by transmitting the deflection value measured by a linear encoder module to a dedicated display device through wireless communications. The present invention is advantageous in that an operator can measure the deflection of a crank shaft quickly and conveniently since the deflection value measured by a digital sensor is transmitted in real time to a dedicated display device through wireless communications.

Description

technical field [0001] The invention relates to a measuring system for measuring crankshaft deflection of a marine engine. More specifically, it relates to a measuring system for measuring crankshaft deviation, the measuring system transmits the deviation value measured by the linear encoder module to a dedicated display device through wireless communication. Background technique [0002] Generally, a marine diesel engine includes cylinders, pistons, crankshafts, etc. When the crankshaft is assembled with the base plate and main bearing housing, it cooperates with the connecting rods to convert the reciprocating linear piston motion into rotation. The crankshaft is the most expensive part of the engine, generally accounting for more than 10% of the engine price. [0003] figure 1 A crankshaft 1 of a large size diesel engine typically used on board is shown. The crankshaft comprises a crank throw 2 , a thrust shaft 3 , a main journal 4 and a flange journal 5 . [0004] T...
