Description
Technical field
The present invention relates to a kind of linear movement pick-up series connection dual-redundancy structure.
Background technology
Two remaining linear movement pick-up generally adopts in aviation aircraft fly-by-wire flight control system and engine system, when the object of its pair of remaining design itself is that one group of winding coil breaks down, another organizes winding startup work for subsequent use, ensures that the normal performance of sensor exports.Current existing pair of remaining linear movement pick-up substantially all adopts the two paralleling model unshakable in one's determination of double winding.Although this type of linear movement pick-up dual-redundancy structure in parallel is widely used, for two remaining linear movement pick-ups that some radial dimension space requirements are higher, parallel-connection structure just cannot meet its requirement.How to meet radial dimension narrow and small, sensor can be made again to reach two remaining requirement, is main contents of the present invention simultaneously.
Summary of the invention
The purpose of this utility model proposes the two remaining linear movement pick-up of a kind of series connection, greatly reduces the two remaining linear movement pick-up radial dimension of original parallel connection, possesses the two remaining requirement of sensor simultaneously.
The technical scheme that the utility model is taked is, a kind of series connection dual-redundancy structure linear movement pick-up, comprise lining 1, left and right stator, socket mounting cylinder 6, left fastening spiro loop 2, right fastening spiro loop 5, coil assembly 14, iron core part 16, it is characterized in that: sensor right shell body 4 is inserted in the right stator of composition in right casing 3, be fixed on socket mounting cylinder 6 by two right fastening spiro loops 5, left shell 13 is inserted in the left stator of composition in left outside shell 15, be fixed on socket mounting cylinder 6 by left bung flange 12, lining 1 is connected to the end of left outside shell 15, coil assembly 14 is had in the stator of left and right, an iron core part 16 is had as linear movement pick-up mover between the hole in coil assembly 14, cylindrical connector 8, pressing plate 7 are fixed on socket mounting cylinder 6 by pad 9, spring washer 10, each four of screw 11 respectively.
Lining 1 by laser weld at left outside shell 15 end, form anti-oil structure, coil assembly 14 is had in the stator of left and right, coil assembly 14 there are serial two windings, have an iron core part 16 between the hole of winding as linear movement pick-up mover, iron core part 16 is connected two by a connecting rod and unshakable in one's determination is formed series iron-core structure.Winding portion 14 is formed by two windings on a skeleton part, composition cascade coil assembly 14, and iron core part 16 is that a connecting rod is connected two and unshakable in one's determinationly formed series iron-core structures.
The advantage that the utility model has and beneficial effect: have employed a kind of in-line linear movement pick-up structure, by two groups of winding techniques on a skeleton part.Meanwhile, two iron cores of two remaining are assemblied on a connecting rod and form cascaded structure.Effectively reduce the radial dimension of sensor, make original space that radial can only can only meet single redundancy sensor, invented the linear movement pick-up of the series connection dual-redundancy structure meeting double redundant sensors requirement.
