Split type automatic balancing device for realizing on-line automatic balance of rotating machine

Abstract

The invention discloses a mechanical device for realizing the on-line automatic balance of a rotating machine. The device is of a split type structure, and comprises two parts of a split type moving ring and a split type stationary ring, wherein a split type transitional sleeve is connected with a rotating main shaft and the moving ring, and plays a role of supporting the moving ring; the series mounting and fixation are realized for all split components of the stationary ring in the axial direction through stationary ring set bolts; a split structure is adopted by the stationary ring; the stationary ring enwraps the moving ring in the circumferential direction; the split surfaces of all the split components of the moving ring are connected respectively by adopting ways of a bolt, a plug-in type, a connecting piece and the like; all the split components of the moving ring are subjected to the series mounting and fixation in the axial direction through moving ring set bolts. By using the split type structure of the mechanical device, an automatic balancing device is enabled to not only be applicable to the development of a novel product but also be applicable to an in-service rotating appliance; the simplification and the convenience of an automatic balancing head in mounting and disassembly processes are promoted greatly; the assembly and the disassembly of the automatic balancing device can be completed without needing to disassemble an original device; the application and popularization of the automatic balancing device are facilitated.

Description

technical field [0001] The invention relates to a split type automatic balancing device for realizing on-line automatic balancing of a rotary machine, and belongs to the technical field of automatic balancing of rotary machines. Background technique [0002] Rotating machinery is an essential and important part of industrial production. Common rotating machinery includes steam turbine rotors, centrifugal compressors, industrial gas turbines, high-speed ultra-precision grinding machines, large fans, and aero engines. With the development of rotating machinery in the direction of high speed, high precision and large size, the requirements for controlling the vibration of rotating machinery are also getting higher and higher. [0003] The rotor is the most important part of all kinds of rotating machinery. Excessive vibration of the rotor will lead to bad consequences such as rubbing of moving and static parts of the rotating machinery, bearing wear and tear, unit shutdown for ...
