Abstract
A kind of mixer carrying roller tapered sleeve locking device, belong to technical field of engineering components, purpose is to reduce the fault rate of mixer, its technical scheme is, composition includes locking nut and stop crotch, the locking nut is matched somebody with somebody with the roller carrier shaft of mixer by screw thread and merges the tapered sleeve end abutted against between roller carrier shaft and self-aligning roller bearing, crotch caulking groove is provided with the outside of locking nut, the stop crotch is L shape, one bar straight-arm is caught in the crotch caulking groove on the outside of locking nut, and another straight-arm is attached on the end face of roller carrier shaft and be fixedly connected with roller carrier shaft.The utility model prevents tapered sleeve from loosening and utilizes the stop crotch being fixedly connected with roller carrier shaft to prevent locking nut from rotating using locking nut, compared with traditional check washer, stop crotch intensity is big, it is fixed, locking nut can be more effectively prevented from and tapered sleeve loosens, so as to reduce the fault rate of mixer, the normal operation of equipment ensure that.
Description
Technical field
A kind of carrying roller tapered sleeve locking device used on the mixer of iron and steel enterprise is the utility model is related to, belongs to engineering
Component technology field.
Background technology
Once, second drum mixer is the visual plant in steel enterprise sintering workshop, mainly by cylinder, carrying roller and driving section
It is grouped into, the bearing installed on roller carrier shaft is typically the self-aligning roller bearing of circular cone endoporus, and self-aligning roller bearing passes through cone
Set is fixed on roller carrier shaft, and the endoporus of tapered sleeve is cylindrical hole match with roller carrier shaft, outer surface for in self-aligning roller bearing
The circular conical surface that hole matches.At present, the tapered sleeve on mixer carrying roller is fixed by the locking nut of its one end, locking
Check washer is provided between nut and tapered sleeve, causes tapered sleeve to loosen to prevent locking nut from unscrewing.But due to mixer be
Run under eccentric heavy load and heeling condition, therefore the locking nut of Idler bearing and tapered sleeve are easy to loose phenomenon occur,
Cause bearing heating or even damage, it is also possible to triggering production accident when serious, huge economic loss is caused to enterprise.And
Because weight of equipment is big, once bearing breaks down, its emergency repair time is longer, can have a strong impact on being normally carried out for production.Therefore,
The tapered sleeve locking device for developing a kind of high reliability is very necessary.
Utility model content
The purpose of this utility model is the drawback for prior art, there is provided a kind of mixer carrying roller cone of high reliability
Locking device is covered, to reduce the fault rate of mixer, it is ensured that equipment normal operation.
Problem described in the utility model is realized with following technical proposals：
A kind of mixer carrying roller tapered sleeve locking device, composition include locking nut and stop crotch, the locking nut
Matched somebody with somebody by screw thread with the roller carrier shaft of mixer and merge the tapered sleeve end abutted against between roller carrier shaft and self-aligning roller bearing, locked
The outside of nut is provided with crotch caulking groove, and the stop crotch is L shape, and the crotch that one bar straight-arm is caught on the outside of locking nut is embedding
In groove, another straight-arm is attached on the end face of roller carrier shaft and is fixedly connected with roller carrier shaft.
Above-mentioned mixer carrying roller tapered sleeve locking device, the straight-arm that each stop crotch is attached in carrying roller axial end point to carrying roller
The center of axial end.
Above-mentioned mixer carrying roller tapered sleeve locking device, the straight-arm that the stop crotch is attached in carrying roller axial end pass through welding
Mode and carrying roller axis connection.
Above-mentioned mixer carrying roller tapered sleeve locking device, the stop crotch set 2~4, their axis around roller carrier shaft
It is uniformly distributed.
The utility model prevent tapered sleeve from loosening using locking nut and utilize the stop crotch that is fixedly connected with roller carrier shaft come
Locking nut is prevented to rotate, compared with traditional check washer, stop crotch intensity is big, fixed, can more efficiently prevent
Only locking nut and tapered sleeve loosen, and so as to reduce the fault rate of mixer, ensure that the normal operation of equipment.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is scheme of installation of the utility model on mixer carrying roller.
Each list of reference numerals is in figure：1st, roller carrier shaft, 2, ring oiler, 3, bearing block, 4, self-aligning roller bearing, 5, tapered sleeve, 6,
Locking nut, 7, stop crotch, 8, end cap, 9, crotch caulking groove.
Embodiment
Referring to Fig. 1, the utility model is made up of locking nut 6 and stop crotch 7.Locking nut 6 is spun on the support of mixer
On roll shaft 1, its outside is provided with multiple crotch caulking grooves 9, and stop crotch 7 is L shape, and the end of one bar straight-arm is caught in locking nut
In the crotch caulking groove 9 in 6 outsides, another straight-arm is welded on the end face of roller carrier shaft 1.
Shown in Fig. 2, tapered sleeve 5 is pressed into the endoporus of self-aligning roller bearing 4, is embraced with roller carrier shaft 1 and the inner ring of self-aligning roller bearing 4
Extremely, the intrusion of tapered sleeve 5 is adjusted by impact and rotational lock nut 6, after being adjusted in place, will be locked with stop crotch 7
Nut 6 is locked, to reach locking purpose.
The steel plate that stop crotch 7 uses thickness to be 25mm for 20mm, width makes, and ensures and the crotch on locking nut 6
Caulking groove 9 is fitted close.The quantity of stop crotch 7 is 2~4, is 3 in Fig. 1, uniform on the end face of roller carrier shaft 1 to choose three
Position is welded, and the end of stop crotch 7 must be directed at the end face center of roller carrier shaft 1, ensures the shearing force minimum born, and want two
Side full weld, postwelding coating will be cleaned out, it is ensured that when mixer operates under heavy duty, eccentric load and heeling condition, locking screw
Mother 6 and tapered sleeve 5 will not loosen.
During maintenance down, carrying roller end cap 8 is opened, the lubricating oil on locknut 6 is locked in observation, sees if there is the vestige of loosening,
Then with 200 tons of jack stand cylinders, the load of carrying roller is reduced, after cleaning out lubricating oil, stop crotch 7 is cut off, screws lock
Tight nut 6.Find never occurred tapered sleeve after improvement and loosen situation, it is seen that the locking stopping effect of the present apparatus shows through repeatedly maintenance
Write, not only extend the service life of carrying roller but also also mitigate the labor intensity of maintenance, reduce equipment maintenance cost.
Above example is only that preferred embodiment of the present utility model is described, not to of the present utility model
Scope is defined, and under the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff is to this practicality
The various modifications and improvement that new technique scheme is made, the protection domain that claims of the present utility model determine all should be fallen into
It is interior.
