Abstract

The invention relates to a non-concentric friction type electromagnetic brake technology, in particular to a friction type electromagnetic brake of a helicopter collective pitch security device. The non-concentric friction type electromagnetic brake comprises a shell, a transmission shaft, a friction block, an electromagnetic clutch, a friction disk assembly, a turbo-worm assembly, a pinion, an inner gear ring, a swinging shaft and a swinging rod. According to the non-concentric friction type electromagnetic brake, a butterfly-shaped friction disk with double-faced friction and the electromagnetic clutch are adopted for braking, the space staggered gear transmission structure is adopted, the volume, the size and the weight are reduced, power loss is reduced, and braking torque is improved;and according to the structure, the electromagnetic brake slows down the movement speed of an output shaft during overload and slipping, so that a pilot can conduct manual switching processing timely, and the helicopter flying reliability is improved.

Description

technical field [0001] The invention relates to a design technology of a friction electromagnetic brake. Especially the friction electromagnetic brake of the helicopter's total safety device. Background technique [0002] Electromagnetic brakes are widely used in industry, aerospace and other fields. When used as a helicopter overall security device, the electromagnetic brake is one of the important components of the helicopter control system. Its function is mainly as a braking mechanism for the helicopter's overall security device. , when autopilot air pressure altitude hold or radio altitude hold, ensure that the collective distance is not lower than 8 degrees, so as to ensure the safety of the helicopter. [0003] The friction electromagnetic clutch has the advantages of simple structure, strong manufacturing process, convenient installation, sensitive action, no noise, energy saving, long life and wide applicability. The friction electromagnetic clutch is mainly compo...
