It is bigger, and Conventional upright motor positioning bearing is generally deep groove ball bearing or angular contact bearing, can only bear axial force ＜
10000N, as axial force ＞ 10000N, above-mentioned bearing cannot then meet vertical machine operation and bear to require, it is therefore desirable to design
A kind of vertical machine rolling bearing system for bearing larger axial force.
Utility model content
The purpose of this utility model is to provide a kind of vertical machine rolling bearing system for bearing larger axial force.
To realize that the purpose of this utility model is adopted the technical scheme that：The device includes internal bearing cover, bearing, bearing
Seat, oil scraper ring, oil fuel tube, bearing end cover, stop washer, nut and oil exit pipe, wherein, the shaft shoulder of the bearing holder (housing, cover) mounted in electric machine main shaft
Place, and by oil scraper ring, stop washer and nut axial restraint, bearing is radially fixed by bearing block, the outer ring of bearing and axle
Bearing gap coordinates, and bearing is fixed with outside the internal bearing cover and bearing being sleeved on electric machine main shaft respectively with the both sides of bearing block
Lid, two lids are respectively equipped with groove with the binding site of bearing, and the wherein groove on internal bearing cover is constituted with the chamber of bearing outer ring
Shoe cream room, the groove on bearing end cover constitutes oiling chamber with the chamber of bearing roller.
The bearing uses spherical roller thrust bearing.
The bearing end cover is provided with oil filler point, and the one end in hole connects with oiling chamber, the other end be packed in bearing end cover
On oil fuel tube connection.
The outage being communicated with the bearing end cover and bearing block, the one end in hole connects with shoe cream room, the other end with
It is packed in the oil exit pipe connection on bearing end cover.
The larger axial force vertical machine rolling bearing system being made according to such scheme, bearing is rolled using spherical roller thrust
Dynamic bearing, can make vertical machine bear larger axial thrust, and centering self-aligning capability is more preferably, compared with angular contact bearing,
The basic dynamic load rating of spherical roller thrust bearing of same inner diameter is 4~5 times of angular contact bearing, the maximum axial that can be born
Power is 3 times or so of angular contact bearing, can reach the effect for bearing more than 30000N axial forces.In addition, using spherical roller
The unique indoor design of thrust bearing and the effect of pumping that the lubricant grease to filling is produced, can not only be more beneficial for bearing
Lubrication, and grease lubrication is relatively low to external condition requirement, it is not necessary to petrol station is set, and working service more facilitates, both avoided Lou
Oily equivalent risk, effectively reduces cost again.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
Referring to Fig. 1, a kind of larger axial force bearing device of vertical motor of the present utility model, the device include internal bearing cover 1,
Bearing 2, bearing block 3, oil scraper ring 4, oil fuel tube 5, bearing end cover 6, stop washer 7, nut 8 and oil exit pipe 9, wherein, 2 sets of bearing
At the shaft shoulder of electric machine main shaft 12, and by oil scraper ring 4, stop washer 7 and the axial restraint of nut 8, bearing 2 passes through bearing block
3 is radially fixed, and outer ring and the gap of bearing block 3 of bearing 2 coordinate, and bearing 2 is fixed with and is sleeved on electricity respectively with the both sides of bearing block 3
Internal bearing cover 1 and bearing end cover 6 on owner's axle 12, two lids are respectively equipped with groove with the binding site of bearing 2, in its middle (center) bearing
Groove on lid 1 constitutes shoe cream room 10 with the chamber of bearing outer ring, and the groove on bearing end cover 6 is constituted with the chamber of bearing roller
Oiling chamber 11.The bearing end cover 6 is provided with oil filler point, and the one end in hole connects with oiling chamber 11, the other end be packed in bearing
Oil fuel tube 5 on enclosing cover 6 is connected.The outage being communicated with the bearing end cover 6 and bearing block 3, the one end in hole and oil storage
Chamber 10 is connected, and the other end is connected with the oil exit pipe 9 being packed on bearing end cover 6.The bearing 2 is rolled using spherical roller thrust
Bearing, because the raceway of its bearing is built with substantial amounts of asymmetric roller, possesses excellent adaptation between roller and raceway, so that
The load distribution on whole roller is optimized, and centering self-aligning capability is more preferable.Vertical machine can be made to bear larger axial direction push away
Power, compared with angular contact bearing, the basic dynamic load rating of spherical roller thrust bearing of same inner diameter be angular contact bearing 4~
5 times, the maximum axial force that can be born is 3 times or so of angular contact bearing, and through actual test, the bearing arrangement can reach and bear
The practical function of more than 30000N axial forces.
By the grease up in bearing, its lubricating grease injects oiling chamber 11 by oil fuel tube 5, is produced inside bearing 2
Raw pumps under active force, and lubricating grease is transferred to shoe cream room 10 from oiling chamber 11, then is discharged to outside motor by oil exit pipe 9, can
To realize not shutting down filling and discharging lubricating grease, lubricant grease is produced using the unique indoor design of spherical roller thrust bearing
The raw effect of pumping, forms flowing of the lubricant grease from the small end of roller towards large end face, so as to be more beneficial for the lubrication of bearing,
And grease lubrication is relatively low to external condition requirement, it is not necessary to set petrol station, working service more facilitates, it is to avoid oil leak equivalent risk,
Also effectively reduce cost simultaneously.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This practicality is new
The technology contents of the not detailed description of type are known technology.
