Problems solved by technology
[0004] When installing the compressor impeller in the prior art, the rotor shaft of the supercharger is usually pressed tightly on the V-shaped iron, which may easily cause the rotor shaft of the supercharger to slip on the V-shaped iron, so that the specified installation torque cannot be achieved, resulting in loose after use
In addition, the slippage of the rotor shaft can easily cause the wear of the journal, which affects the quality of product installation

The invention relates to the technical field of impeller assembly, in particular to a marine supercharger compressor impeller installation tool, comprising a base, a pair of left brackets erected on the upper left end of the base, and a pair of right brackets erected on the upper right end of the base brackets, the pair of left brackets are arranged at intervals in the front-rear direction, the pair of right brackets are arranged at intervals in the front-rear direction, a first beam is connected between the tops of the pair of left brackets, and the pair of right brackets are arranged at intervals in the front-rear direction. A second beam is connected between the top of the right bracket, the first beam is provided with a first positioning locking device for positioning the supercharger rotor shaft journal, and the second beam is provided with a supercharger for positioning The second positioning locking device of the rotor shaft journal. The invention ensures the installation torque of the compressor impeller and improves the installation quality of the product.
Description
technical field [0001] The invention relates to the technical field of impeller assembly, in particular to a mounting tool for a compressor impeller of a marine supercharger. Background technique [0002] A supercharger is a high-speed rotating device. In order to ensure its working balance and reliability, a balance test must be carried out on its rotor to ensure its operating quality. Because the unbalanced force when the rotor rotates will not only increase the extra load of its bearing, but also cause the blades on the rotor to fall off and the surge of the supercharger. [0003] When the supercharger rotor is dynamically balanced, the compressor impeller is required to be installed on the supercharger rotor shaft and the balance test is carried out at the same time. Since the installation torque of the compressor impeller is 1200N / M according to the design requirements, it is required that we fix the rotor first when installing the impeller, so as to ensure that the im...
