Abstract

The invention discloses a multifunctional annunciator applied to a transmission system of a helicopter and belongs to the technical field of detection. The multifunctional annunciator comprises a magnetic scrap monitoring unit, a temperature sensing component and a filter component, an integrated design is adopted, and the combined monitoring and processing to the abnormal conditions such as abrasion, flaking and fracture faults of a reducer of the transmission system of the helicopter and abnormal temperature of oil are achieved; furthermore, two pairs of magnetic pole structures and high temperature-sensing nickle elements are adopted, so that the annunciator is great in magnetic absorption capacity and high in sensitivity, and the design of structure optimization is adopted, so that the annunciator is small in size, low in weight and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of detection, and more specifically relates to a multifunctional signal device applied to a transmission system of a helicopter. Background technique [0002] In order to ensure the safety of the personnel and equipment of the helicopter, it is required to monitor the operation status of the critical parts of the helicopter in real time so as to make timely response. The transmission system reducer is a key moving part of the helicopter. It is necessary to monitor the operating status of the reducer in real time. The monitoring not only includes the lubricating oil temperature in the lubricating system, but also the damage, peeling and fragmentation of rotating parts such as gears, shafts and bearings. The alarm can be reported in time, so that the helicopter pilot can deal with it in time. [0003] In the prior art, the monitoring of the reducer of the transmission system of the helicopter is realized thro...
