Description
Technical Field
The utility model belongs to the technical field of crankshaft flywheel support of diesel engines, and particularly relates to a crankshaft flywheel alignment support device of a large diesel engine.
Background
The crankshaft of large diesel engine is a power transmission part on diesel engine, and in the course of high-speed operation of crankshaft the piston is driven to continuously do work in diesel engine so as to implement work. Specifically, the crankshaft is operated at a high speed by a flywheel at a power input end, but the crankshaft is an important component having a complicated structure and poor rigidity, and is easily deformed by bending.
The flywheel assembled on the crankshaft of the large diesel engine has larger mass, and the crankshaft is more easy to generate deflection, so that the measurement arm distance difference is influenced. Especially when the diesel engine is idle for a long time, the flywheel is not connected with the coupling or other output systems, and even inelastic deformation is possible.
Therefore, in order to reduce the influence of the flywheel on the crankshaft, it is currently more common practice to use an external support to support the flywheel, balance the gravity of the flywheel, and reduce the deformation of the crankshaft caused by the gravity influence of the flywheel on the crankshaft. It is common practice to support the flywheel by means of, for example, support rods, brackets, etc.
However, this method has a disadvantage that when the device is needed, the turning operation (i.e., turning the flywheel, judging whether the flywheel can rotate normally, avoiding the occurrence of a jamming condition, i.e., preprocessing before starting up) is first needed, and therefore, the support (support rod, support seat) for loading the weight of the flywheel needs to be detached for the turning operation without resistance. However, the support for supporting the flywheel is difficult to detach due to high friction force with the flywheel, and the flywheel is easy to scrape and slide, so that sliding marks are generated. Secondly, dismantle the support under the laborious circumstances, lead to the inefficiency of operation, still need support under the flywheel again after the follow-up shut down, it is very complicated loaded down with trivial details.
And the supporting object is adopted to support, so that the supporting object cannot be guaranteed to be supported at the gravity center position of the flywheel, the supporting effect of the supporting object is not ideal, and the deformation influence of the weight of the flywheel on the crankshaft cannot be fully reduced.
