Embodiment Construction
[0047] Below we will further describe in detail the connection between the hydraulic dynamometer and the marine diesel engine and the adjustment method thereof in conjunction with the accompanying drawings and specific embodiments, but the scope of protection required by the present invention cannot be limited by this.
[0048] The connection between the hydraulic dynamometer and the marine diesel engine and its adjustment method include the following contents:
[0049] 1. For the connection and installation of the intermediate shaft and the hydraulic dynamometer, please refer to figure 1 ;
[0050] 1.1 The connection between the intermediate shaft A3 and the hydraulic dynamometer A4 is carried out outside the test bench. According to the rotation direction of the marine diesel engine A1, the connection end between the hydraulic dynamometer A4 and the marine diesel engine A1 should be selected so that the marine diesel engine A1 is The rotation direction of the car is consisten...

The invention discloses a connection and adjustment method for a hydraulic dynamometer and a marine diesel engine. The marine diesel engine and the hydraulic dynamometer are connected through an intermediate shaft. The method comprises: 1) a step of connecting the intermediate shaft with the hydraulic dynamometer, namely a step of hoisting the intermediate shaft, adjusting deviation values of a large flange of the intermediate shaft and a flange of the hydraulic dynamometer in all directions on the outer circumference to be consistent, with the concentricity being within 0.05 mm and screwing aconnecting bolt; 2) a step of connecting the intermediate shaft with a crankshaft of the diesel engine, namely a step of hoisting the hydraulic dynamometer and the intermediate shaft which are connected into a whole to a test bed platform, with a gap of more than 2 mm being reserved between the small flange and the crankshaft flange, primarily adjusting the position of the hydraulic dynamometer by using an adjusting shim plate, adjusting the concentricity and the crack surface of the two flanges to meet the requirements that the crack surface value is less than or equal to 0.05 mm and the deviation is less than or equal to 0.05 mm, compensating and adjusting the deflection of the intermediate shaft and the deflection of the shaft of the hydraulic dynamometer, installing a friction plate between the small flange of the intermediate shaft and the crankshaft flange after adjustment is finished, and then fastening the small flange and the crankshaft flange. The method achieves the good effects of improving the precision, and being simple to operate, safe and reliable.
Description
technical field [0001] The invention relates to a manufacturing process of a marine low-speed diesel engine, in particular to a connection between a hydraulic dynamometer and a marine diesel engine and an adjustment method thereof, belonging to the technical field of marine diesel engine manufacturing. Background technique [0002] During the production and commissioning of marine diesel engines, in order to minimize the damage to the parts of the diesel engine and the vibration of the whole diesel engine due to the torsion caused by the misalignment of the shaft system, it is necessary to adjust the installation of the hydraulic dynamometer. Such as figure 1 As shown, the hydraulic dynamometer A4 is connected to the crankshaft of the marine diesel engine A1 through the intermediate shaft A3. The two ends of the intermediate shaft A3 in the middle position are respectively a large flange A31 and a small flange A32. The small flange A32 is connected to the The crankshaft of ...
