Abstract

The invention provides an electric brush grinding device and rotary electric equipment. The electric brush grinding device comprises a grinding component, a fixing component and an electric brush clamping component. The grinding component is fixed to a rotary shaft of the rotary electric equipment; the fixing component is arranged on an outer shell of an electric brush grinding chamber and used for fixing the electric brush clamping component; electric brushes are placed in the electric brush clamping component; and the grinding component rotates along with rotation of the rotary shaft to grind the electric brushes. In this way, in the working process of the rotary electric equipment, the grinding component rotates along with rotation of the rotary shaft of the rotary electric equipment; in the rotation process, the electric brushes are pressed towards the grinding component by a pressing component, under limitation of a limiting portion of the fixing component, according to a preset grinding quantity, the electric brushes are grinded to enable the end face shapes of the electric brushes to be adaptable to the surfaces of current collection sliding rings.

Description

Technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a brush grinding device and rotating electrical equipment. Background technique [0002] Generally speaking, rotating electrical equipment mostly uses brushes and slip ring structures as the current introduction devices for rotating electrical components. For larger rotating electrical equipment, the number of brushes is large and needs to be replaced frequently to ensure the normal introduction of current. [0003] After the brush is replaced, the side of the new brush facing the slip ring is flat, and its contact with the slip ring is line contact. In the initial stage of replacement, it often generates heat due to poor contact, which can easily cause ignition during operation and ablation of current collector slip. Occurrence of ring failures. [0004] Based on this, the present invention provides a brush grinding device and rotating electrical equipment to s...
