Abstract

The invention relates to the technical field of online dynamic balance of spindles, in particular to online dynamic balance compensation device and method for high-speed motorized spindles. Basically, two compensation devices are used to synthesize an unbalance vector to balance the unbalance vector of a rotor of a motorized spindle. Compared with the prior art, the compensation device is simple in structure and convenient to install. During compensation, the unbalance vector of the rotor is balanced by changing relative positional relation between a balance ring with the unbalance vector and the rotor in the compensation device, weight is not increased or decreased, mass of the rotor is not destroyed, and stoppage is avoided. In addition, elastic elements are added to two sides of the balance ring, so that constant application of external force to the balance ring during compensation is avoided and energy consumption is lowered.

Description

technical field [0001] The invention relates to the technical field of online dynamic balance of a spindle, in particular to an online dynamic balance compensation device for a high-speed electric spindle and a compensation method thereof. Background technique [0002] When the rotor of a rotating machine rotates, due to the uneven distribution of material density, defects in the processing blank, machining errors, assembly errors or design during machining, the mass distribution of the rotor is more or less uneven, resulting in uneven rotor mass. A matter of balance. The vibration caused by rotor imbalance is the most common phenomenon in rotating machinery vibration, especially for high-speed rotating equipment. Although many large rotating machines have been balanced with a single rotor in the manufacturing plant, due to the difference between the on-site operating conditions and the balancing conditions of the manufacturing plant, the balance state of the shafting may b...
