Technical field
The present invention relates to self-lubricating knuckle bearing and manufacture field, be specifically related to the lining of a kind of self-lubricating knuckle bearing
Pad and outer ring Internal Spherical Surface adhering device.
Background technology
Blank, this series products master is there is in current China in the correlation technique of aviation precision self-lubricating knuckle bearing
Want dependence on import.At present, the self-lubricating layer of self-lubricating knuckle bearing has multiple, fabric self-lubricating layer application phase
To more.Textile type self-lubricating knuckle bearing is the oscillating bearing of a kind of specific form without supplemental lubrication agent,
Due to features such as its coefficient of friction are low, abrasion resistance is excellent, bearing capacity is strong, non-maintaining, therefore extensively should
For fields such as transportation, engineering machinery, defence and militaries.Textile type self-lubricating knuckle bearing is mainly by axle
Holding inner ring, bearing outer ring, liner three part composition, liner is bonded in bearing outer ring Internal Spherical Surface, and in bearing
Circle spherical outside surface constitutes spherical pair, and during work, liner forms the transfer membrane of low shear strength between friction pair,
Play self-lubricating function.
Bonding and the curing process of the selflubricating liner of self-lubricating knuckle bearing be bearing mnanufacture key technology it
One, its technical process is: apply certain bonding agent, by the liner of dipping solidification, pastes ball in outer ring
Face, by sticker keep liner bear certain pressure, be then placed in hot environment, through the time with
The control of temperature, it is achieved solidification process.Bonding with curing process in, except the selection of bonding agent, and
In technique for sticking beyond the control of the technological parameter such as temperature, time, power, bonding action implementation method and device
The bonding basic technology condition implemented with curing process, the effectiveness of bonding action implementation method and device with
Reliability, directly affects the bonding of bonding liner and solidification quality, thus affects the property of self-lubricating knuckle bearing
Energy.Although the technical research about bonding agent, curing process parameter is more, but is bonded in by selflubricating liner
Equipment and technology research in the outer ring Internal Spherical Surface of oscillating bearing is less, particularly with integral outer ring's self-lubricating joint
Bearing, bearing internal external circle trap extruding assembling before, it is necessary to by bonding for liner be cured to outer ring Internal Spherical Surface
On, especially for the bearing of reduced size, the skill that its bonding action bonding with curing process realizes with device
Art applied research is less, and disclosed patent does not has with document.
Summary of the invention
Present invention aim at providing that a kind of liner is bonding uniformly, all directions keep concordance, adhesive effect good,
Liner thickness is uniform, play uniform self-lubricating oscillating bearing liner adhering device.
For achieving the above object, have employed techniques below scheme: the invention mainly comprises bracing frame, end cap,
Screw, liner and oscillating bearing outer ring blank, support frame as described above is cylinder or the cuboid of an end closure
Shell structure, offers gathering sill at sealing end, installs end cap at opening by screw；Gathering sill is pacified
Insert sliding sleeve, in axial direction process slot in sliding sleeve, at the sliding sleeve within bracing frame sealing end correspondence gathering sill
Sealing end screw thread inserts a load screw；The corresponding each gathering sill position of inner surface at end cap is offered accordingly
Hole, location, in hole, location, assign an expanding arbor, described expanding arbor is by the mandrel of band tapering and opening
Seam expansion set forms, and expansion set is enclosed within mandrel exterior, expansion set front end affixed packing ring B, and packing ring B is connected with spring,
Spring at front end connects another packing ring A, and the Small Taper end of mandrel can be inserted through packing ring B, spring, packing ring A
Entering in gathering sill in the slot of sliding sleeve, the steep-taper end of mandrel assigns in hole, location；It is socketed in the middle part of expansion set
Tensioner ring, is cased with liner and oscillating bearing outer ring blank outside tensioner ring successively.
The slot of described sliding sleeve is at the bottom of cone tank.
It is provided with the dismounting semi-ring of outwardly convex away from one end of conical head at mandrel.
Described tensioner ring two ends be the face of cylinder, middle part be protruding sphere, offer cross expansion or contraction joints at axial direction.
Described expanding arbor is standard component, and the taper ratio of mandrel is 1:16 tapering.
Work process approximately as:
Unload screw, take off end cap, tensioner ring, liner and oscillating bearing outer ring base are installed outside expansion set successively
Material, inserts mandrel one end in tensioner ring, and the mandrel other end inserts in the hole, location in end cap, then by end cap weight
Newly it is buckled on bracing frame, utilizes screw sealing fixing.Now, load screw is rotated, by load screw
Precession promotes and slides in gathering sill and move horizontally, by sliding sleeve extrusion spring, spring to one pressure of expansion set,
Make the expansion set of split move axially along the mandrel of band tapering, and finally produce radial deformation；Tensioner ring is enclosed within swollen
On expansion core axle, it axially offers cross expansion or contraction joints, and spherical shape and oscillating bearing outer ring blank in the middle part of tensioner ring
Internal Spherical Surface shape is identical, and the expanded radially of expansion set drives tensioner ring radial deformation, utilizes the tensioner ring expanded outwards to support
Play liner, make liner be fitted tightly in the blank Internal Spherical Surface of oscillating bearing outer ring.
Compared with prior art, present invention have the advantage that technical process is less to liner damage, liner
Bonding uniformly, all directions keep concordance, bonding after liner can be made in hot environment solidification process to keep holding
By certain pressure, oscillating bearing liner bonding quality can be improved, and be capable of the joint of reduced size
The bonding action of bearing bush.
