Description
Technical field
The invention belongs to design field, relate to a kind of flexible Strapdown Gyro Using upper end cover assembly.
Background technology
For flexible Strapdown Gyro Using, when rotating with the driving shaft vertical direction, deflection angle is detected and output electrical signals by the angle signal device that is contained in mutually perpendicular two change in coordinate axis direction on housing when housing; This signal is added in corresponding torquer coil after demarcating resistance R via the force feedback amplifier, produces moment and makes the rotor precession, until deflection angle is zero; At this moment, the torquer electric current is directly proportional to angular speed, demarcates ohmically magnitude of voltage and reflects carrier angular speed size.Therefore, the structure of annunciator, torquer and performance are directly determining structure and the precision of flexible Strapdown Gyro Using.Traditional flexible gyroscope (comprising platform-type flexible gyroscope and strapdown flexible gyroscope) (as shown in Figure 1), its upper end cover 4 there is no the function of carrier being installed as other any parts, its Main Function is that inertia rotors is operated in is sealing, inner near the gyro of vacuum state, annunciator iron core 1, torquer stator module 2 are installed on gyro housing 12, be positioned at rotor 13 belows, approach with motor component 14 distances.
For this traditional structure, its deficiency is: gyro machine and annunciator, torquer distance approach, and the electromagnetic interference of motor and heating are larger on the impact of annunciator, torquer; On the other hand, this version is difficult to effectively reduce the gyro volume.
Summary of the invention
The objective of the invention is to propose the flexible Strapdown Gyro Using upper end cover assembly that a kind of volume is little, cost is low.
Technical solution of the present invention is: flexible Strapdown Gyro Using upper end cover assembly, comprise four groups of annunciator iron cores, torquer stator module, 12 insulators, upper end cover, grout cable, it is characterized in that, four groups of U-shaped annunciator iron cores are evenly distributed on the outer shroud circumference of upper end cover inner plane, connect firmly as a whole direct machine-shaping with the gyro upper end cover, the rotor upper surface is as the armature of annunciator, and eight annunciator coils are enclosed within the two ends of four groups of U-shaped annunciator iron cores successively; 12 insulators take three as one group of Even Sintering in the middle of two adjacent groups annunciator iron core, as the inside and outside tie point of annunciator coil and torquer coil lead.Wherein, in every group of insulator, two insulators on both sides are on the outer shroud circumference of upper end cover inner plane, and middle insulator is on the interior ring circumference of upper end cover inner plane; The torquer stator module is made of moment device seat, H lug plate, four circular arc type torquer coils and reinforcing ring, the H lug plate is bonded on the bonding plane of moment device seat side, four circular arc type torquer coils surround a cylinder, the cylinder lower surface is bonded on the circumference of moment device seat, upper surface and reinforcing ring are bonding, alignment pin on corresponding upper end cover and the location hole on the torquer stator module are fixed on the torquer stator module by screw the center of gyro upper end cover inner plane; 12 welding holes are arranged on grout cable, and its relative position is identical with insulator, take pin hole as benchmark, it is welded on 12 insulators of upper end cover inner plane successively.
Be in two insulators on the outer shroud circumference of upper end cover inner plane in described every group of insulator, with the angle of insulator on the interior ring circumference that is in the upper end cover inner plane be 10 °.
The advantage that the present invention has and beneficial effect: the present invention is divided into up and down two body structures with flexible Strapdown Gyro Using, has reduced gyro machine electromagnetic interference and heating to the impact of annunciator, torquer, and the precision that improves little gyro is had positive effect; Upper end cover settling signal device iron core processing at gyro realizes that annunciator iron core and upper end cover are integrated, has effectively dwindled the gyro volume, has reduced number of spare parts and assembly work amount; The torquer assembly is contained in upper end cover, has reduced gyro when the speed operation of big angle, the impact of large current heating on the gyro performance; In the present invention, insulator on upper end cover, is convenient to reduced volume by direct sintering, can carry out fine finishining to the upper end cover after sintering again again, guarantees the tolerance of part; This structure is convenient to gyro assembly and reprocessing, and when annunciator or when torquer breaks down or performance does not meet the demands, the gyrorotor that need not to dismantle just can be fixed a breakdown, thereby does not affect gyro assembly and debug results.Thereby improved gyro productivity ratio, reduced part and scrap.
