Abstract

The invention belongs to the technical field of sensors, in particular to a high-reliability, high-precision double-redundancy non-contact resolver-type angular displacement sensor. Including installation shell, protective shell, first stator winding, fixed spacer magnetic sleeve, second stator winding, rotating cylinder, first bearing, second bearing and integrated rotor assembly; integrated rotor assembly includes rotating shaft, first rotor iron Core, dynamic spacer sleeve and second rotor core. The invention optimizes the processing technology of the stator and rotor iron core, adjusts the position of the stator winding, sets the magnetic isolation sleeve, integrates the rotating shaft, and adds a limit ring to effectively improve the angle measurement accuracy and anti-vibration ability of the sensor, and reduce the output consistency of the two channels error and avoid crosstalk between channels. At the same time, it solves the problems of difficult processing and assembly adjustment process, poor manufacturability, and low production efficiency brought about by the traditional structure.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a high-reliability, high-precision double-redundancy non-contact resolver-type angular displacement sensor. Background technique [0002] As the mechanical transmission system on the aircraft is more and more replaced by the electronic control system, the application of the rotary transformer angular displacement sensor in the aircraft system is also becoming more and more extensive. They provide precise angular position information to the flight control system. [0003] The brushes and slip rings used to transmit signals in the traditional rotary transformer angular displacement sensor are the weakest links in its reliability, and the sliding contact between them limits its life and reliability. In addition, contact resolvers often generate noise and are not suitable for some occasions that are sensitive to noise. After adopting reasonable brushless technology in the design, c...
