Description

A kind of easy-maintaining bearing block

Technical field

The utility model relates to bearing apparatus technical field, especially a kind of easy-maintaining bearing block.

Background technique

Rotation between existing bearing block and shaft, under prolonged working condition, meeting between shaft and bearing block Phase mutual friction, and then lead to the abrasion of bearing and shaft, just needs replacing entire bearing and bearing block during this time, in this way at This comparable height, is unfavorable for producing.

Utility model content

In order to overcome the shortcomings of that existing bearing block damage maintenance is complicated at high cost, the utility model provides a kind of easily dimension Bearing block is repaired, in bearing block ontology two sides fixing bearing, steel bushing is worn in the bearing hole of bearing, then shaft pierces into steel bushing, Steel bushing is locked in shaft by lock ring circle, steel bushing and bearing interference fit are installed, and allow steel bushing in rotation on bearings While drive shaft rotate together.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of easy-maintaining bearing block, including bearing Seat ontology, the bearing block ontology on both sides of the middle are respectively equipped with bearing one and bearing two, wear in the bearing one and bearing two Equipped with steel bushing, the steel bushing both ends are equipped with lock ring circle one and lock ring circle two.

Further, the bearing groove one and bearing groove two for fixing bearing are equipped with including bearing block ontology on both sides of the middle.

Further, including between bearing groove one and bearing groove two it is equipped with through-hole.

Further, the bearing bore dia of bearing one and bearing two is greater than including through-hole diameter, through-hole diameter is less than bearing One and bearing two outside diameter.

Further, including steel bushing is connected with bearing one and the interference fit of bearing two.

Further, the notch that steel bushing is tightened for lock ring circle one and lock ring circle two is equipped with including steel bushing.

Further, the baffle rings of fixing bearing one and bearing two are respectively provided with including bearing block ontology on both sides of the middle One and baffle rings two.

The utility model has the beneficial effects that a kind of easy-maintaining bearing block of the utility model, in bearing block ontology two sides Fixing bearing wears steel bushing in the bearing hole of bearing, and then shaft pierces into steel bushing, and steel bushing is locked at shaft by lock ring circle On, steel bushing and bearing fit are installed, and allow steel bushing to drive shaft to rotate together while rotation on bearings, steel bushing plays The effect of shaft is protected, while the lock ring of two sides encloses the effect of positioning, avoids steel bushing and drive shaft that lateral displacement occurs, Bearing is that the maintenance and replacement of bearing are facilitated after bearing damage in the bearing groove being fixed in bearing block main body.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the cross-sectional view at the place Figure 1A-A；

Fig. 3 is the structural schematic diagram of steel bushing in Fig. 1.

1. bearing block ontology in figure, 2. bearings one, 3. bearings two, 4. steel bushings, 5. lock ring circles one, 6. lock ring circles two, 7. axis Hold slot one, 8. bearing grooves two, 9. through-holes, 10. notches, 11. baffle rings one, 12. baffle rings two.

Specific embodiment

If Fig. 1 is the structural schematic diagram of the utility model, a kind of easy-maintaining bearing block, including bearing block ontology 1, the axis It holds 1 on both sides of the middle of an ontology and is respectively equipped with bearing 1 and bearing 23, be equipped with steel bushing in the bearing 1 and bearing 23 4,4 both ends of steel bushing are equipped with lock ring circle 1 and lock ring circle 26.

In conjunction with shown in Fig. 1-3, one, 1 on both sides of the middle of bearing block ontology be equipped with for fixing bearing bearing groove 1 and bearing Slot 28 is equipped with through-hole 9, bearing 1 and bearing 23 by interference fit and is fixed on axis between bearing groove 1 and bearing groove 28 It holds in slot 1 and bearing groove 28.9 diameter of through-hole is greater than the bearing bore dia of bearing 1 and bearing 23, and 9 diameter of through-hole is less than The outside diameter of bearing 1 and bearing 23 can guarantee to will not continue to internally be displaced after bearing is stuck in bearing groove in this way, It also ensures wearing for steel bushing 4 simultaneously, normally wearing for steel bushing 4 will not be blocked.Because steel bushing 4 is the bearing hole for being threaded through bearing In, so the outer wall of steel bushing 4 and bearing 1 and bearing 23 interference fit connect, ensure that steel bushing 4 in bearing in this way On normal rotation.Steel bushing 4 is equipped with the notch 10 that steel bushing 4 is tightened for lock ring circle 1 and lock ring circle 26, the notch 10 difference The both ends of steel bushing 4 are set, and convenient for wearing for shaft, which is less than steel bushing 4 and is exposed at the length outside bearing block, in this way Also avoid influencing the cooperation of steel bushing 4 and bearing while ensure that its effect.1 on both sides of the middle of bearing block ontology is respectively equipped with use Gear is utilized after bearing is fixed in bearing groove in fixing bearing 1 and the baffle rings of bearing 231 and baffle rings 2 12 Plate ring covers bearing groove notch, to play the role of fixing bearing, avoids bearing and shifts in the process of work.

In use, then bearing notch is fixed with baffle rings, in the axis of bearing in bearing block ontology two sides fixing bearing Steel bushing is worn in bearing bore, then shaft pierces into steel bushing, steel bushing 4 is locked in shaft by the way that lock ring circle is self-locking, steel bushing and bearing It is installed by interference fit, steel bushing 4 is allowed to drive shaft to rotate together while rotation on bearings, in this case tightly It is the friction between steel bushing 4 and bearing, steel bushing 4 plays the role of protecting shaft, while the lock ring of two sides encloses the work of positioning With, avoid steel bushing drive shaft occur lateral displacement, bearing is to work as bearing in the bearing groove being fixed in bearing block main body Baffle rings are removed after damage can remove bearing, no replacement is required entire bearing block, facilitate maintenance and replacement.

It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait Effect, but all will fall within the protection scope of the utility model.
