Methods of Balancing Components

Abstract

The invention relates to a method for balancing a component (1), in particular a rotor of an electric machine, by means of pins (11, 11'), which are inserted into prefabricated openings (5, 7, 9) in the component (1), wherein , the assembly (1) is balanced by fixing pins (11, 11') of different lengths, cross-sections and cross-sectional shapes into corresponding openings (7, 9) in the assembly (1). Furthermore, the pin (11, 11') can consist of a plurality of parts (13, 13') and the method is used to achieve an increased balancing quality step-by-step in one or more stages. In this way, the unbalance of the assembly (1) can be significantly reduced—and at the same time the weight, space requirement and moment of inertia of the assembly (1) are saved. In addition, the method has the possibility of automation.

Description

technical field

[0001] The invention relates to a method for balancing a component, in particular a rotor of an electric machine. Furthermore, the invention relates to an electric machine assembly, which is balanced by such a method, and an electric machine, which has such an assembly. The invention also relates to a device with which components are balanced by means of the method according to the invention. Background technique

[0002] Components that rotate during their use often require balance. In balancing, mass compensation occurs axially and radially with respect to the axis of rotation so that the axis of rotation of the assembly coincides with the main axis of inertia of the assembly. If the axis of rotation does not coincide with the main axis of inertia, a centrifugal moment occurs when the component rotates, which in particular loads the suspension of the rotating component. This condition is often referred to as the effect of component imbalance. A centrifu...
