Retractable rotor malposition in line adjusting device

Abstract

A retractable rotor malposition in line adjusting device. The device comprises a flange bracket (1), a radial adjusting screw (2), an axial adjusting screw (3) and a lever indicator (4), wherein the flange bracket (1) is connected to the external motor output shaft through the thread of the flange, and the radial adjustment screw (2) is screwed into the threaded through hole of the boss of the flange bracket (1) through the external thread, the axial adjustment screw 3) is screwed into the threaded through hole of the boss of the radial adjustment screw (2) through the external thread, and the lever dial indicator (4) is fixed to the right end of the axial adjustment screw (3). Adjusting the screw depth of the radial adjusting screw (2) to adjust the radial position in the lever indicator (4) measuring end, adjusting the screw depth of the axial adjusting screw (3) to adjust the axial position at the lever indicator (4) measuring end, all the above adjustment methods are used to adjust the position of the measuring end, further are used to regulate the rotor malposition in line. At the same time, the invention can also be used to realize the measuring function of the rotor's own end face and the cylindrical beating.

Description

technical field [0001] The invention relates to a retractable rotor centering adjustment device, which is mainly used for adjusting the centering of the rotor and the output shaft of a motor when the rotor of a high-speed turbo pump of a liquid rocket engine is dynamically balanced at high speed. Background technique [0002] In engineering practice, misalignment faults of rotating machinery are very common, accounting for more than 60% of rotor system faults. Rotor misalignment will cause the system to generate axial and radial alternating forces, which in turn will cause axial and radial vibrations. Rotor movement under misalignment will cause excessive vibration, bearing wear, shaft deflection, friction between rotor and stator and other regenerative failures, which pose a threat to the stable operation of the system and will cause catastrophic accidents in severe cases. [0003] For the high-speed dynamic balance test of the high-speed turbo pump rotor system of the liq...

AI Technical Summary

Problems solved by technology

The laser alignment instrument has high precision, but the equipment is expensive, the operation is complicated, and the adjustment value cannot be monitored in real time during the adjustment process

However, the traditional mechanical meter centering device does not have scalability, single function, and poor positioning accuracy, which can only reach about 0.05mm
