Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0013] See attached Figure 1~3 As shown, this four-degree redundant angular displacement sensor is characterized in that: the sensor includes four identical angular displacement sensor assemblies (1), and each angular position of a four-degree redundant angular displacement sensor displacement sensor assembly (1) includes An angular displacement sensor (9) and a gear (10) connected to the output shaft of the angular displacement sensor (9) and an anti-backlash gear (11) matched together with the gear (10);

[0014] The sensor also includes a hollow U-shaped housing (2), the U-shaped housing (2) and the cover plate (3) are connected together by four screws to form the supporting structure of the entire sensor, and the gear shaft (4) passes through the shaft The bearing (5) and the shaft end bearing (7) are installed on the U-shaped housing (2) and ...

Abstract

The present invention provides a quad redundant angular displacement sensor. The sensor comprises a hollow U-shaped housing (2), the U-shaped housing (2) and a cover plate (3) are connected with each other through two screws to form the support structure of the whole sensor; a gear shaft (4) is installed on the U-shaped housing (2) and the cover plate (3) through inter-axis bearing (5) and a axis-end bearing (7), and the angular displacement sensors (9) of the four angular displacement sensor assemblies (1) are symmetrically installed at the bottom of the U-shaped housing (2) through a small pressing plate (8); and the gears (10) of the four angular displacement sensor assemblies (1) and anti-backlash gears (11) are symmetrically installed in the cavity of the U-shaped housing (2), and the gears (10) and the anti-backlash gears (11) re engaged with the gear of the gear shaft (4). The quad redundant angular displacement sensor is small in size, compact in structure, light in quality and high in reliability.

Description

technical field [0001] The invention is a four-redundancy angular displacement sensor, which belongs to the technical field of product structure. Background technique [0002] In order to meet the requirements of the fly-by-wire flight control system for the throttle control system, with the development of electrical and electronic technology and fly-by-wire engine technology, the throttle console in the mechanical control mode will be gradually replaced by the throttle console in the fly-by-wire mode. The fly-by-wire throttle console can effectively reduce the mechanical transmission link of the throttle control, reduce the weight, and improve the transmission accuracy. However, in order to realize the transmission of the driver's control signal, the fly-by-wire throttle mechanism usually uses an angular displacement sensor instead of the mechanical transmission, which is a key component of the flight control system. Provide signal to realize engine throttle control. [00...
