Abstract

The invention provides an electromagnetic brake and a friction plate assembly thereof, and relates to the technical field of electric power equipment. The friction plate assembly comprises an armature, a friction plate and a baffle plate which are coaxially overlapped, wherein a connecting column is connected to one side of the baffle plate; the armature sleeves the connecting column and can slidealong the connecting column; the friction plate is limited between the baffle plate and the armature; the armature, the friction plate and the baffle plate are magnetic; mutual repelling force is generated between the armature and the friction plate; and the mutual repelling force is also generated between the friction plate and the baffle plate. A clearance is formed between a stator and the friction plate in electrifying engineering; the friction plate is rotated between the armature and the baffle plate under the effect of magnetic repelling force, so that two end surfaces of the frictionplate in rotating are prevented from contact and friction, and the dust, noise and abrasion caused by friction are minimized, and as a result, the reliability of the electromagnetic brake is ensured.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an electromagnetic brake and a friction plate assembly thereof. Background technique [0002] Electromagnetic brake is an automatic actuator in electric power equipment. It mainly plays the role of transmitting power and controlling motion in the mechanical transmission system. Electromagnetic brake is an important basic component, integrating mechanical, electrical and electronic technologies, and is mainly used in rotating mechanisms. (such as motor devices, etc.) precise control and braking. [0003] When the electromagnetic brake is installed in the servo motor, the friction plate of the electromagnetic brake rotates with the rotating shaft of the motor. When the brake is energized, the friction plate will deflect and produce bad noise, and the deflection will cause one side of the friction plate to rub against the armature or the baffle , generating dust and unne...
