Description
Technical field
The present invention relates to a kind of bearing fixing device, more particularly to a kind of oscillating bearing fixing device.
Background technology
Oscillating bearing is widely used in aviation field, and it will also while axial-radial load is born in the course of the work
Certain axial load is born, oscillating bearing axial displacement can not occurs relative to bearing block or be pressed when bearing axial load
Go out.When carrying out regular inspection maintenance to airborne vehicle it is often found that oscillating bearing weares and teares or is corroded, so as to need to carry out bearing
Change, i.e., from new installation oscillating bearing and need to be fixed.The fixation procedure of oscillating bearing is that the receipts pressure of oscillating bearing is to pass through
Fixing tool is extruded mounting groove 61, is plastically deformed mounting groove 61, and a part of material of mounting groove 61 is filled
To mounting surface 51, bearing is set not to be subjected to displacement when bearing axial load.The fixation of prior art is to be fixed on fixing tool
On press, frock is received the extruding mounting groove 61 of pressure surface 8 fixing tool loading certain pressure using press and be plastically deformed
So as to be fitted in the fixation completed on mounting surface 51 to oscillating bearing, and industrial bottom bracket uses casting mostly, and it is pacified
The deviation from circular from of dress face 51 is larger, so above-mentioned frock has the following disadvantages：1st, fixing tool needs to be arranged on press, so that axle
The fixation held needs to clamp aeronautical maintenance part progress rehandling, complex operation；2nd, when the deviation from circular from of mounting surface 51 is larger
When frock receive pressure surface 8 can not allow mounting groove 61 be plastically deformed material all laminating mounting surfaces 51, cause the part of mounting surface 51 not
It can be filled, so that the axial carrying capacity to bearing after fixation has an impact.
The content of the invention
Technical problem solved by the invention is to provide pass a kind of simple to operate and that mounting surface is preferably filled after fixing
Bearings fixing device.
The technical solution adopted by the present invention is：Oscillating bearing fixing device, including oscillating bearing, bearing block, the joint
Bearing face is provided with mounting groove, and the bearing block is provided with mounting surface, and it includes rolling edge mechanism, gland, thrust bearing, compression spiral shell
It is female；The rolling edge mechanism includes fixed middle bar, base, retainer, neck, roller；The base lower surface is provided with neck；The bottom
Seat is connected with fixed middle bar；The fixed middle bar is passed through to be connected with gland, thrust bearing, clamp nut successively after oscillating bearing centre bore
Connect；The clamp nut is to be threadedly coupled with the connection of fixed middle bar；The retainer is threadedly coupled with base outer surface；The rolling
Son is embedded in neck and fixed by retainer, and the roller after fixing, which is located at, installs groove center and parallel with mounting surface.
Further, the roller is multiple and uniform with corresponding neck.
Further, the base termination is hexagon, and the fixed middle bar lower end is hexagon.
Further, there is annular knurl the retainer outer surface.
The beneficial effects of the invention are as follows：The oscillating bearing fixing device of the present invention, it is simple to operate, install and close in aeronautical maintenance
Without Awaiting Parts are installed on press during bearings, reduce rehandling and clamp, the time of saving improves maintenance effect
Rate, reduce in maintenance process damage aerospace partses risk, meanwhile, mounting surface 51 fill relatively fully, bearing receive pressure effect compared with
It is good, improve the oscillating bearing axial carrying capacity after installing.

Embodiment
As Figure 1-4, oscillating bearing fixing device, including oscillating bearing 6, bearing block 5, the end face of oscillating bearing 6
Provided with mounting groove 61, the bearing block 5 is provided with mounting surface 51, and it also includes rolling edge mechanism 1, gland 2, thrust bearing 3, compression spiral shell
Mother 4；The rolling edge mechanism 1 includes fixed middle bar 11, base 12, retainer 13, neck 14, roller 15；The lower surface of base 12
Provided with neck 14；The base 12 is connected with fixed middle bar 11；It is described it is fixed in bar 11 pass through after the centre bore of oscillating bearing 6 successively with pressure
Lid 2, thrust bearing 3, clamp nut 4 are connected；The clamp nut 4 is to be threadedly coupled with the connection of fixed middle bar 11；It is described to keep
Frame 13 is connected with the outer surface thread of base 12；The roller 15 is embedded in neck 14 and fixed by retainer 13, after fixing
Roller 15 is located at and the center of mounting groove 61 and parallel with mounting surface 51.
Illustrate with reference to specific embodiment:
Referring to up and down above and below Figure of description in this specification.Fig. 2 be the present invention a kind of embodiment, base 12 with
The end of bar 11 connection in fixed, figure is that threaded connection can also be from welding or integrative-structure etc., and the lower surface of base 12 is provided with card
Groove 14, the position of neck 14 is according to the Position Design of corresponding mounting groove 61, and the outer surface of base 12 is threadedly coupled with retainer 13, rolled
Son 15 is embedded in neck 14.First roller 15 is embedded in after neck 14 during assembling and rotates retainer 13 so that retainer 13 is blocked
