Change, i.e., from new installation oscillating bearing and be fixed.It is by receiving pressure instrument to peace that the fixation procedure of oscillating bearing, which receives pressure,
Tankage 61 is extruded, and is plastically deformed mounting groove 61, and a part of material of mounting groove 61 is filled into bearing block installation
Face 71, bearing is set not to be subjected to displacement when bearing axial load.Traditional receipts pressure is will to receive pressure frock to be fixed on press, is utilized
Press presses frock loading certain pressure to make the generation plastic deformation of mounting groove 61 complete to fix the receipts pressure of oscillating bearing to receiving.It is above-mentioned
Pressure frock is received to have the following disadvantages：Receiving pressure frock and needing to be arranged on needs to aeronautical maintenance portion on press so as to which pressure is received in bearing installation
Part carries out rehandling and clamped；Bearing installation will be carried out again after maintenance component decomposition by being not easy to the needs of the dress maintenance component of folder.
Utility model content
The technical problem that the utility model solves is to provide a kind of oscillating bearing that can be compressed oscillating bearing and receive pressure and received
Pressure device.
The technical solution adopted in the utility model is：Oscillating bearing receives pressure device, including oscillating bearing, bearing mounting base,
The oscillating bearing end face is provided with mounting groove；It also includes receiving briquetting, fixed middle bar, gland, thrust bearing, clamp nut；It is described
Receive briquetting lower surface and be provided with the projection being adapted to mounting groove；The receipts briquetting is connected with fixed middle bar；The fixed middle bar passes through and pass
It is connected successively with gland, thrust bearing, clamp nut after bearings centre bore；The clamp nut is connected as screw thread with fixed middle bar
Connection.
Further；The fixed middle bar is adapted to oscillating bearing centre bore.
Further：The projection surrounds circle.
Further：The fixed middle bar lower end is hexagon.
The beneficial effects of the utility model are：Oscillating bearing of the present utility model receives pressure device, installs and closes in aeronautical maintenance
During bearings do not have to Awaiting Parts are installed on press, reduce rehandling and clamp, save the time improve maintenance effect
Rate, reduce the risk that aerospace partses are damaged in maintenance process.

Embodiment
As shown in Figure 1, 2, oscillating bearing receives pressure device, including oscillating bearing 6, bearing mounting base 7, the oscillating bearing 6
End face is provided with mounting groove 61：It also includes receiving briquetting 1, fixed middle bar 2, gland 3, thrust bearing 4, clamp nut 5；The receipts briquetting
1 lower surface is provided with the projection 11 being adapted to mounting groove 61；The receipts briquetting 1 is connected with fixed middle bar 2；It is described it is fixed in bar 2 pass through with
It is connected successively with gland 3, thrust bearing 4, clamp nut 5 after oscillating bearing centre bore 62；The clamp nut 5 and fixed middle bar 2
It is connected as being threadedly coupled.
Upper and lower in this specification refer to relative Figure of description up and down.As shown in Figure 1, Figure 2, Figure 3 shows, receive in briquetting 1
Heart hole is connected with fixed middle bar 2, and connected mode can select threaded connection, welding or integrative-structure, and the present embodiment is threaded connection；Institute
Receipts briquetting 1 lower surface is stated to be adapted to receiving the mounting groove 61 of pressure oscillating bearing 6 provided with projection 11, described raised 11.Projection 11 is with closing
The adaptation of mounting groove 61 of bearings 6 refers to：The position of projection 11 pressure is received according to the Position Design of the mounting groove 61 of oscillating bearing 6
When ensure that projection 11 be located at the center of mounting groove 61, the medial surface 111 of projection 11 is parallel with mounting groove medial surface 611, outside raised 11
Side 112 is parallel with bearing block mounting surface 71.It is described it is fixed in bar 2 through oscillating bearing centre bore 62 it is fixed in after successively with gland 3,
Thrust bearing 4, clamp nut 5 connect, i.e., fixed middle bar 2 is each passed through gland 3, thrust axis again after passing through oscillating bearing centre bore 62
It is threadedly coupled after holding 4 holes with clamp nut 5.Bar 2 coordinates preferred gap to coordinate with gland 3, the hole of thrust bearing 4 in fixed.When receiving pressure,
It is appropriate to rotatably compress nut 5 so that receiving the compression mounting groove 61 of briquetting 1 brings it about plastic deformation, after keeping impaction state 1min
Unclamp nut and remove device completion receipts pressure.Pressure device is received using the oscillating bearing of above-mentioned technical proposal, rotatably compresses nut to receiving
Briquetting provides thrust, therefore need not dismantle aeronautical maintenance part or part during replacing installation oscillating bearing and be transported to pressure
On bed, clamped so as to reduce rehandling, reduce the risk that part is damaged in maintenance process, improve maintenance efficiency, together
When the utility model be easy to carry, it is simple to operate, reduce the dependence to maintenance of equipment, place.
It is described to determine in middle bar 2 and oscillating bearing in order to which projection 11 can be directed at mounting groove 61 well when ensureing that compression receives pressure
Heart hole 62 is adapted to, i.e., fixed middle bar 2 coordinates with oscillating bearing center interporal lacuna, preferred gap 0-0.5mm.
In order to ensure to receive pressure effect and improve efficiency, described raised 11 surround the circle being adapted to mounting groove, one when receiving pressure
It is secondary to complete to receive side, improve efficiency.
Clamping for pressure device, six sides that the fixed middle lower end of bar 2 is fixed for ease of spanner are received for the ease of oscillating bearing
Shape.
