SU1348681A1 - Arrangement for balancing axial-piston machine - Google Patents

Abstract

The invention relates to a balancing technique and can be used in axial-piston pumps and compressors with a shim washer. The aim of the invention is to increase the efficiency of balancing the rotor of the machine by reducing the radial and axial unbalanced inertia forces. In case 1, shaft 2 is placed, on which ring 4 is installed with corrective mass 6 fixed on it. In radial channels 8 ring 4 are placed, with the possibility of mixing the ends of elastic rods 7 equally spaced around the ring, the other bent ends are fixed with rotatable and fixed in the lugs 9 of the shaft 2. The ring surface 11 contacts the roller 12 of the stop 13 fixed on the housing 1 with the possibility of moving along the axis of the shaft 2. Selecting the corrective mass 6, its position around the circumference of the ring 4, n the ring is attached to the axis of the shaft 2 and the position of the stop 13, the radial and axial unbalanced inertia forces are reduced. 1 hp f-ly, 2 ill.

Description

with the surface 11 of the ring 4 and fix the stop in this position. The offset of the ring 4 in this case is compensated by the deflection of the rods 7 and their movement in the channels 8 of the ring.

When the shaft 2 rotates, the rotational and reciprocating movement of the corrective mass 6 fixed on the ring 4 compensates both radial and

Invention Formula opportunity the movements in the radial channels 8 of the ring 4, and the other ends curved in the form of a loop are fixedly rotatable and fixed in the lugs 9 of the shaft 2 by means of the axis 10. The surface 11 of the ring 4 is constantly in contact with the roller 12 of the stop 13 fixed to the housing 1 movable along the axis of the shaft 2 and locked. The device works as follows. The rotor 14 of the axial-piston machine is rotated. Along the axis of the shaft 2 and perpendicular to it, the vibrations due to unbalanced forces of inertia of the moving parts of the machine are measured. Corrective masses 5 and 6 are determined from the measurement results, their angular position is fixed to rings 3 and 4. The angle of inclination of ring 4 to shaft axis 2 is also determined, the ring is inclined at this angle, turning rods 7 on axes 10 , and fix, clamping the curved ends of the rods in the lugs 9.
