Technical field
The present invention relates to vehicle technology field, more particularly to a kind of tilt table device.
Background technology
Advance, retrogressing, the left and right inclination of rotary aircraft are controlled by pitch, and servomechanism, which is promoted, to be tilted
Lower wall, causes the upper disk of inclination to tilt together, then the connecting rod tilted by connection on upper disk transmits the force to rotor and produces rotor
Periodic angle of attack variation, and reach the purpose of control.
Current pitch is provided with pitch and lower pitch, and universal bearing, pitch are installed in upper pitch part
Hypsokinesis of leaning forward, left-leaning Right deviation by gimbal suspension bearing complete.After blade rotates, upper pitch follows lifting airscrew
Main shaft is rotated together.The Jing Quan of lower pitch and upper pitch are separated.After helicopter starts, the bearing in pitch is also together
Rotate.So bearing is for flight safety, the loss of engine output has conclusive influence.Existing pitch
Bearing can just accomplish maintenance only when installation or overhaul, influence the life-span of pitch, influence the life-span of aircraft,
And existing design is a bearing, when pitch is being acted, the non-perpendicular state of lifting airscrew main shaft, bearing rapid wear
It is bad.
The power for being more than axial power, also radial direction that now bearing is subject to.Two power superpositions, form torsion, easy damaged
Bearing, directly reduces the reliability of helicopter.
The content of the invention
For above-mentioned technical problem, inventor is had found when pitch is being acted, the non-perpendicular shape of lifting airscrew main shaft
The power of state, the now power, also radial direction that are more than axial direction that bearing is subject to.Two power superpositions, formation torsion, easy damaged bearing,
Directly reduce the reliability of helicopter.
Therefore, the present invention provides a kind of tilt table device, facilitates the maintaining of pitch, and the power of reduction pitch is damaged
Consumption, adds the bearing of different-diameter, for bearing torsion, improves the reliability of aircraft, extend pitch life-span and
The life-span of aircraft.
The invention provides a kind of tilt table device, at least including relatively turnable upper pitch and lower pitch, institute
State pitch and lower pitch warp beam is held and is provided with the oiling for being communicated to the bearing on interconnection, the lower pitch
Hole, the bearing includes gimbal suspension bearing, clutch shaft bearing and second bearing, and the clutch shaft bearing and second bearing are coaxially to set
The bearing for the different-diameter put.
Further, the moving-coil rotated with the gimbal suspension bearing is provided with the upper pitch.
Further, the clutch shaft bearing and second bearing are ball bearing.
Further, the lower pitch is arranged with Jing Quan, and the oil filler point is communicated to the bearing through the Jing Quan
Place.
Further, the bearing is provided with oil seal sealing ring.
Further, the oil seal sealing ring includes upper oil seal sealing ring and lower oil seal sealing ring.
Further, the upper pitch and the concentric setting of lower pitch.
A kind of tilt table device that the present invention is provided, adds the bearing of different-diameter, for bearing torsion, improves winged
The reliability of row device, extends the life-span of pitch and the life-span of aircraft.
A kind of tilt table device that the present invention is provided, adds fuel filler neck design, by setting oil filler point in lower pitch,
Oil filler point is communicated at bearing, is easy to the maintenance of pitch in use in the future.
Brief description of the drawings
Some specific embodiments of the present invention are described in detail by way of example, and not by way of limitation with reference to the accompanying drawings hereinafter.
Identical reference denotes same or similar part or part in accompanying drawing.It should be appreciated by those skilled in the art that these
What accompanying drawing was not necessarily drawn to scale.In accompanying drawing：
Fig. 1 is the structural representation of tilt table device according to an embodiment of the invention；
Fig. 2 is a kind of configuration schematic diagram of tilt table device shown in Fig. 1.
Embodiment
Fig. 1 is a kind of structural representation of tilt table device according to an embodiment of the invention.Fig. 2 is shown in Fig. 1
A kind of configuration schematic diagram of tilt table device.Referring to Fig. 1 and Fig. 2, a kind of tilt table device of the invention, including can be relative
The upper pitch 8 rotated and lower pitch 9, upper pitch 8 is interconnected with lower pitch 9 through bearing, on the lower pitch 9
It is provided with the oil filler point 5 for being communicated to the bearing.The upper pitch 8 and the concentric setting of lower pitch 9
Specifically, in a specific embodiment, the bearing between upper pitch 8 and lower pitch 9 closes to be universal
Bearings 2, pitch lean forward hypsokinesis or left-leaning Right deviation relies on gimbal suspension bearing 2 and completed.Alternatively, the universal pass
The first ball bearing 3 and the second ball bearing 4 are provided between bearings 2 and the lower pitch 9.The He of first ball bearing 3
Second ball bearing 4 can be the different bearing of radius.
Further, the moving-coil 1 rotated with the gimbal suspension bearing 2 is provided with the upper pitch 8.It is described to have a down dip
Swash plate 8 is arranged with quiet circle 7, and the oil filler point 5 is communicated at the bearing through the quiet circle 7.The bearing is provided with oil sealing
Sealing ring.Oil seal sealing ring includes upper oil seal sealing ring (not shown) and lower oil seal sealing ring 6.
After blade rotates, upper pitch 8 follows lifting airscrew main shaft to rotate together.Following quiet circle 7 is relied on
Bearing, is separated with moving-coil.After helicopter starts, the bearing in pitch is also rotated together.So bearing is for flight safety,
The loss of engine output has conclusive influence.
In actual use, when pitch is being acted, the non-perpendicular state of lifting airscrew main shaft.Now bearing by
Be more than axial direction power, also radial direction power.Two power superpositions, the torsion of formation is by the first ball bearing 3 and the second ball
Bearing 4 is undertaken respectively so that bearing is hardly damaged, and improves the safety and reliability of aircraft.
