Abstract
The utility model is related to a kind of flanged and locking device oscillation bearings.Triple seal composition including outer ring, inner ring, roller and both sides, triple sealing device are made of sealing ring, retainer and spring ring, and outer ring outer diameter carries flange, and is threaded on the other side outer diameter relative to flange；Gasket and locking nut are housed at the screw thread of outer ring outer diameter.The utility model solves the assembly problem of bearing very well relative to standard rolling bearing, eliminates the problems such as divergence type shell middle (center) bearing deforms.Integrated design bearing not only alleviates bearing weight, also reduces the weight of host, additionally reduces the cost of aircraft and bearing itself.
Description
Technical field
The utility model belongs to construction design of journal bearings field, and in particular to a kind of swinging axle with flange and locking device
It holds.
Background technology
Airframe（The positions such as wing flap, slat）With oscillation bearing, by being limited by installation space, axis, radial limit
Position cannot use conventional method, in addition it is also contemplated that therefore the non-maintaining problem of bearing it is next to be badly in need of a kind of application specific architecture bearing
Solve installation and maintenance issues.
Invention content
The utility model provides a kind of flanged and locking device oscillation bearing, and the assembly to solve oscillation bearing is asked
Topic, and the problem of divergence type shell middle (center) bearing deforms.
The utility model is that technical solution used by solving its technical problem is to provide a kind of flanged and locking device
Oscillation bearing.Triple seal composition including outer ring, inner ring, roller and both sides, the triple sealing device is by sealing ring, lock
Circle and spring ring are constituted, and the outer ring outer diameter carries flange, and is threaded on the other side outer diameter relative to flange；Outside
It encloses and gasket and locking nut is housed at the screw thread of outer diameter.
Further, the locating slot there are one being opened up at the screw thread of outer ring outer diameter for gasket positioning.
Further, the flange carries 30 ° of inclined-planes by outer end face side, and is lacked being circumferentially designed with rectangular positioning
Mouthful.
Further, the outer ring raceway, roller rolls surface, inner ring raceway are ball-track.
Further, two side external surface of the inner ring raceway is designed to spherical surface.
Further, inner ring inside diameter surface, on the center line of bearing, there are one oil groove and uniformly distributed three oil for design
Hole.
Further, the sealing ring is made of PTEE materials.
Relative to standard rolling bearing, this oscillation bearing solves the assembly problem of bearing very well, eliminates in divergence type shell
The problems such as middle (center) bearing deforms.This design of integrated bearing not only alleviates bearing weight, also reduces the weight of host,
Additionally reduce the cost of aircraft and bearing itself.
Involved oscillation bearing in the utility model, lightweight has also been taken into account while realizing the functional requirement of aircraft
Design, prodigious contribution is made that for the development of China's aviation field.

Specific implementation mode
Below in conjunction with attached drawing and specific embodiment, the utility model is described in further detail.
It is the structural schematic diagram of the utility model as shown in Figure 1.Including the triple close of outer ring 1, inner ring 2, roller 4 and both sides
Envelope composition, the triple sealing device are made of sealing ring 5, retainer 6 and spring ring 7, and 1 outer diameter of the outer ring carries flange 3, and
It is threaded on the other side outer diameter relative to flange；Gasket 8 and locking nut 9 are housed at the screw thread of 1 outer diameter of outer ring.
There are one locating slots 10 for design at 1 outer-diameter threads of outer ring, are used for the positioning of gasket 8, and adjust using locking nut 9
The gap of bearing installation.
Bearing outer ring ball track, rolling element rolling surface, inner ring raceway are ball-track, make bearing that can not only do and rotate
Movement, can also swing in certain angular range.
As shown in Fig. 2 the utility model outer ring and flange section structural schematic diagram, 1 outer diameter flange design of outer ring is at by outer end
Face side carries 30 ° of inclined-planes, and is circumferentially being designed with locating notch 11, makes it have the effect of locking nut.
As shown in Fig. 3 the utility model inner ring structure schematic diagrames, 2 raceway of inner ring, two side external surface is designed to spherical surface, can be with
So that sealing ring 5 is contacted for line with 1 outer surface of inner ring, reduce frictional force, makes bearing that there is very low moment of friction.
2 inside diameter surface of inner ring designs on the center line of bearing there are one oil groove 12 and uniformly distributed three oilholes 13, this
Sample can facilitate replacement and the supplement of lubricant, be convenient for the maintenance of bearing.
Bearing both sides carry the sealing ring of PTFE material, substantially prolong the non-maintaining time of bearing.
The utility model is bright relative to standard rolling bearing, this body bearing solves the assembly problem of bearing, eliminates very well
The problems such as divergence type shell middle (center) bearing deforms.This design of integrated bearing not only alleviates bearing weight, also mitigates
The weight of host, additionally reduces the cost of aircraft and bearing itself.
