Marine supercharger compressor impeller mounting tool

Abstract

The invention relates to the technical field of impeller assembly, in particular to a marine supercharger compressor impeller mounting tool. The marine supercharger compressor impeller mounting tool comprises a base, a pair of left supports which are vertically arranged on the upper portion of the left end of the base and a pair of right supports which are vertically arranged on the upper portionof the right end of the base, the pair of left supports are arranged at intervals in the front-back direction, the pair of right supports are arranged at intervals in the front-back direction, a firstcross beam is connected between the tops of the left supports, a second cross beam is connected between the tops of the right supports, a first positioning and locking device used for positioning a shaft neck of a supercharger rotor shaft is arranged on the first cross beam, and a second positioning and locking device used for positioning the shaft neck of the supercharger rotor shaft is arrangedon the second cross beam. According to the marine supercharger compressor impeller mounting tool, the mounting torque of the compressor impeller is ensured, and the product mounting quality is improved.

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...

AI Technical Summary

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
