Problems solved by technology

The current displacement sensor used in the missile launch process cannot meet the high-precision guidance requirements of the missile. Therefore, a high-performance displacement sensor used in the missile launch process has been developed, so that the steering gear can reach the servo when the missile moves. The performance index of the displacement sensor is very necessary

Abstract

The invention relates to a miniature high-precision angle sensor, which includes a housing, a rotating shaft and an end cover connected to the housing, a first bearing and a second bearing are installed inside the housing, the rotating shaft extends into the housing through the end cover and It is rotationally connected with the first bearing and the second bearing, and the first brush and the second brush are installed on the rotating shaft between the first bearing and the second bearing through the installation connector. The first brush Between the second brush and the second bearing, a resistor body is installed on the rotating shaft through a conductive rivet, and the first brush and the second brush are respectively connected to the corresponding surfaces of the rivet and the resistor body. The sliding contact, the resistor body is connected to the outgoing signal line. The invention is compact in structure, has the characteristics of small structural elements, light weight, stable and reliable output signal, and can guarantee its use safety in the specified use period and specified use environment.

Description

technical field [0001] The invention relates to a miniature high-precision angle sensor, in particular to a miniature high-precision angle sensor used in the missile launching process. Background technique [0002] The material of precision guided missiles requires its control system to have high precision, high sensitivity and high reliability. The electric steering gear in the servo action system is one of the important components of the flight control system. The power and static characteristics of the steering gear directly affect the flight performance of the aircraft. Handling performance. Sensors are an important part of electric steering gear. The current displacement sensor used in the missile launch process cannot meet the high-precision guidance requirements of the missile. Therefore, a high-performance displacement sensor used in the missile launch process has been developed, so that the steering gear can reach the servo when the missile is moving. The performa...
