Abstract

The invention belongs to the technical field of small and special aviation electrical machines, and particularly relates to a damping structure of an angular displacement sensor. The damping structure is characterized by comprising a damping mechanism composed of a shifting fork assembly (2), a protection cover (3), end covers (4), end cover screws (5), a lead-out shaft (6) and a pin shaft (7). According to the damping structure of the angular displacement sensor, the requirements for installation and usage can be met on the occasion with the large vibration quantity, the output fluctuation of the angular displacement sensor is avoided, the output precision of angular signals is ensured, and therefore flying safety is guaranteed.

Description

technical field

[0001] The invention belongs to the design technology of aviation micro-special motors, and relates to a damping structure of an angular displacement sensor. Background technique

[0002] Angular displacement sensors are widely used in aircraft, and generally transmit angular displacement signals through shaft connection transmission. The angular displacement sensor converts the angular displacement signal into a voltage signal, which is characterized by small size and high precision, and the resolution is generally measured in seconds. The current angular displacement sensor does not have a shock-absorbing structure, which can basically meet the use requirements in occasions with a small amount of vibration. However, if the installation position has a large amount of vibration, or the transmission shaft connected to the angular displacement sensor is long, the vibration will be amplified by itself. This is likely to cause fluctuations in the output of the a...
