The technical solution of the utility model is：A kind of anti-twisting equipment applied to helicopter inclinator, including ball and socket joint Ball, inactive order lower part and two anti-twist pins, it is characterised in that：The ball and socket joint ball includes inner groovy, annular groove, outer recessed Slot, two inner groovies are symmetrical set inside ball and socket joint ball, and two external grooves are symmetricly set on the outside of ball and socket joint ball, Annular groove is arranged at the circumference of ball and socket joint ball outer edge maximum, the inactive order lower part include two pin mounting holes and Erecting bed, ball and socket joint ball are mounted in erecting bed；Ball and socket joint ball is mounted on erecting bed, and two anti-twist pins pass through two pins Mounting hole is inserted into external groove respectively；The groove width of the external groove is bigger 0.1mm than anti-twist pin diameter between 0.5mm.

According to the anti-twisting equipment as described above for being applied to helicopter inclinator, it is characterised in that：Tank filler sleeve is further included, is added Oilhole is arranged on pin mounting hole side.

According to the anti-twisting equipment as described above for being applied to helicopter inclinator, it is characterised in that：The external groove Groove width is bigger 0.2mm than anti-twist pin diameter.

According to the anti-twisting equipment as described above for being applied to helicopter inclinator, it is characterised in that：The external groove Groove width is bigger 0.3mm than anti-twist pin diameter.

According to the anti-twisting equipment as described above for being applied to helicopter inclinator, it is characterised in that：It further includes in inactive order Portion, the top of inactive order top connection inactive order lower part.

The beneficial effects of the utility model are：First, anti-torsion function is combined in inside inclinator, without individual anti-twisting equipment, letter The structure of inclinator is changed；Second is that can be refueled by tank filler sleeve to anti-twist pin, maintenance easy to repair；Third, the dress of the utility model Reference is put in inclinator, the structure of inclinator can be simplified, reduces equipment manufacturing costs.

Specific embodiment

The technical solution of the utility model is described further below in conjunction with attached drawing.

As shown in Figures 1 to 10, a kind of anti-twisting equipment applied to helicopter inclinator of the utility model includes bearing Joint ball 3, inactive order lower part 8 and two anti-twist pins 9.

As shown in Figure 1, the ball and socket joint ball 3 of the utility model include inner groovy 31, annular groove 32, external groove 33, two A inner groovy 31 is symmetrical set inside ball and socket joint ball 3, and two external grooves 33 are symmetricly set on outside ball and socket joint ball 3 Side, annular groove 32 are arranged at the circumference of ball and socket joint ball 3 outer edge maximum,

As shown in figure 3, the inactive order lower part 8 of the utility model includes two pin mounting holes 81, tank filler sleeve 82, erecting beds 83, tank filler sleeve 82 is arranged on 81 side of pin mounting hole, and ball and socket joint ball 3 is mounted in erecting bed 83.

The ball and socket joint ball 3 of the utility model is mounted on erecting bed 83, and two anti-twist pins 9 pass through two pin mounting holes 81 It is inserted into external groove 33 respectively, the groove width of external groove 33 is more bigger than anti-9 diameter of twist pin, and the groove width of general external groove 33 is than anti-twist pin The big 0.1mm of 9 diameters is between 0.5mm, and preferably 0.2mm, 0.3mm can prevent ball and socket joint ball 3 from existing by anti-twist pin 9 in this way Side-to-side movement in inactive order lower part 8, ball and socket joint ball 3 can only move up and down, so as to play anti-torsion effect.The utility model passes through Tank filler sleeve 82 is to the addition machine oil of the join domain of ball and socket joint ball 3, inactive order lower part 8 and anti-twist pin 9, convenient for the device Maintenance.

The anti-twisting equipment of the utility model is applied in inclinator, and inclinator is further included including slide cartridge 1, feather key 2, Moving plate pressure Lid 5, bearing 6, Moving plate 7.1 inside of slide cartridge is helicopter rotary shaft, and outer groove 11 is symmetrical set on slide cartridge 1.Ball and socket joint ball 3 It is mounted on slide cartridge 1 by two feather keys 2, after installation, feather key 2 is located in outer groove 11 and inner groovy 31, can make in this way Ball and socket joint ball 3 is moved up or down along feather key 2.3 outside setting inactive order top 4 of ball and socket joint ball and inactive order lower part 8.8 top of inactive order lower part connection inactive order top 4,8 middle part outside setting bearing 6 of inactive order lower part, 6 outside setting of bearing are dynamic Disk 7,6 top of bearing setting Moving plate gland 5.The inactive order top 4 of the utility model is fixed on inactive order lower part 8 by screw 10 Top, Moving plate gland 5 are fixed on by screw 10 on Moving plate 7, and bearing 6 is located in Moving plate gland 5 and Moving plate 7, the inside of bearing 6 It is fixed on inactive order lower part 8, the outside of bearing 6 is fixedly connected with Moving plate 7.

The utility model device course of work is：When ball and socket joint ball 3 is moved up and down with slide cartridge 1, pass through anti-twist pin 9 It prevents ball and socket joint ball 3 from being moved left and right inside inactive order lower part 8, and then prevents ball and socket joint ball 3 with respect to inactive order lower part 8 Transverse shifting realizes the function for the twisting that inclinator is prevented in the case where not increasing external wrench device.
