Abstract

The invention relates to rotor balancing during rotation and allows stabilization of the balancing process in the presence of three movable corrective masses moving around the circumference. Three corrective masses with imbalances of 0.5: 0.5: 1.0 of the maximum possible unbalance of the rotor are installed on the rotor, the centers of two smaller corrective masses are diametrically opposed, the larger correction mass is moved until the maximum amplitude of oscillations of the rotor is obtained and measured again move a large correction mass to obtain a minimum oscillation amplitude of the rotor and measure it, calculate the average value of two measured amplitudes, move a large mass to obtain an amplitude count -oscillations of the rotor equal to the calculated amplitude .value, then combine the two smaller imbalances correcting masses, and then move them together to eliminating rotor imbalance. 1 nl (Lu 4a SL; 0 о СР

Description

This invention relates to mechanical engineering and can be used to balance rotors during rotation. The purpose of the invention is to stabilize the balancing process for any one of the value and angle of unbalance of the rotor.

The drawing shows a device for implementing the proposed method.

The device contains a corrective assembly in the form of unbalanced gears K, Kj and KJ, which are corrective masses mounted on the rotor 1 for rotation, and drives the corrective masses in the form of a sum of a lean conical differential 2 with three identical parallel kinematic chains for rotating corrective masses connected at the entrance with control knobs P, P and PJ, and through satellites 3-5 - at the output with corrective masses. A satellite of 6 satellites that synchronizes the rotation of the corrective mass with the rotor speed receives rotation from the rotor through a gear pair (in the form of gear wheels 7 n 8) with a rotor speed divided in half. If balancing is not performed, then the rotation from the rotor is transmitted to the corrector without any reduction, as if the conical differential were not completely i

The method of balancing rotors during activation is implemented as follows.

In the plane of correction of the rotor 1, three corrective masses K, K and K are installed in the form of gears with an imbalance ratio of 0.5: 0.5: 1 of the maximum possible unbalance of the rotor. In addition, a rigid gear wheel 7 is mounted on the rotor. The gears of the differential gear are engaged with the wheel 7 and with correction masses K, K and K, and the rotor is rotated due to the rotation of the carrier 6 satellites with a rotation frequency of two times that of the rotor Correction: the masses will be stationary in relation to the rotor. For balancing, first rotate the handles P and PJ or one of them and set

The centers of smaller masses K and K are diametrically opposed by the coincidence of the marks on the handles P and P,. Then, from the handle PJ, the correction mass Kd is rotated with a large imbalance until the maximum amplitude of the rotor oscillation is measured, the resulting amplitude value is measured, again moved; 1y the mass Kj from the handle P to the minimum amplitude of the rotor 1 oscillation and measured , calculate the average value of the two measured amplitudes, again move the large correction mass K from the RH knob to obtain the amplitude of the rotor oscillations equal to the calculated value of the power amplitude, then, rotating the knobs P and PJ or one of them, combine the cent s two smaller mass corrective K and K can, using the labels on the handles, and then simultaneously rotating the handle P and WG is moved together ,, mass K and Kj to eliminating rotor imbalance.
