This research paper introduces a new technique designed specifically for measuring the phase angle between off-centred symmetrical circular objects, like crankshafts. The purpose is to improve crankshaft inspection machines, enabling more accurate measurements for increasing engine performance and reliability. Measuring the phase angle between the crankshaft pins has been challenging task. The proposed method utilizes LabVIEW algorithms and advanced sensors like LVDT and Optical Incremental encoder which are capable of detecting and analysing the small variations in the phase angle between pins. This technique measures phase angle between pins by the maximum lift phenomena and deviation in maximum lift of pins results phase angle difference as incremental provides angular position.it enables measurements with a high degree of precision, facilitating the reliable detection of any irregularities or deviation in phase angle that may affect crankshaft performance and reliability. Existing methods measures phase angle with high precisions but they have factors which may lead to inaccuracies, one important parameter is crankshafts should be perfectly horizontal otherwise it will affect accuracy. This proposed technique eliminates this variable and provide easy, economical and accurate solution to OEM. The purpose of this teqnique is to utilize it in crankshaft inspection machine that is designed for Tractor OEM. Crankshafts Manufacturing drawings were provided by OEM on whiich all tolerances were mentioned. For phase angle allowable error is 0.25o from the true value So the sensors used for measuring phase angle upto 0.03o . Overall, this research paper presents a promising advancement in crankshaft inspection by introducing a new technique for measuring the phase angle between off-centred symmetrical circular objects as Crankshafts.
