Abstract
The utility model discloses a bearing clearance regulating device for rollers, belongs to a bearing clearance regulating device, and aims to provide a device that can conveniently regulate the bearing clearance of tapered rollers. The bearing clearance regulating device comprises a pedestal ring (8) fixed on a bearing seat (5), a screw shaft (6) used for being supported in the pedestal ring, a regulating sleeve (1) matched with the screw shaft through internal threads, a worm gear (9) fixed on the screw shaft, a worm (7) meshed with the worm gear and a guide mechanism positioned between the regulating sleeve (1) and the pedestal ring (8). The bearing clearance regulating device organically combines the worm gear driving with the screw rod driving, so that the roller clearance can be regulated through regulating the position of a bearing outer ring even if the relatively large clearance is generated because of the worn-out bearing roller, the service life of the bearing is prolonged, and the frequency of production halts for maintenance is lowered; the bearing clearance regulating device is simple in structure, convenient for clearance regulating and high in regulating accuracy, and is the device used for regulating the bearing clearance of the rollers.
Description
Technical field
The utility model relates to a kind of bearing clearance adjusting device, relates in particular to a kind of horizontal mill roll bearing slack adjuster.
Background technology
As everyone knows, the roll of horizontal mill is to be all bearing on bearing block by being positioned at the taper roll bearing at its two ends.Because the impact load that roll rotational speed is high, bear is large, bearing roller easily occurs loosening; Not only can cause rolling board size overproof, but also can aggravate bearing wear and cause rolls damage.
At present, the roll chock of horizontal mill does not generally all have bearing clearance adjusting device, because roll is huge and heavy, once bearing roller occurs to become flexible, can only shut down replacing bearing; Not only maintenance load is large, maintenance cost is high, but also impact production is normally carried out.
Summary of the invention
For the above-mentioned defect existing in prior art, the utility model aims to provide the roll bearing slack adjuster in a kind of conveniently adjusted taper roll bearing gap.
To achieve these goals, the utility model by the following technical solutions: it comprises the seat ring that is fixed on bearing block, be bearing in lead screw shaft in this seat ring, the regulating sleeve coordinating with this lead screw shaft by internal thread, be fixed on worm gear in this lead screw shaft, and worm screw and the guiding mechanism between regulating sleeve and seat ring of this worm gear engagement.
The outer wall of regulating sleeve has gathering sill, and described guiding mechanism forms with suitable feather key or the guide finger of this gathering sill in being fixed on seat ring; The outer wall of regulating sleeve has guide surface, and described guiding mechanism forms by being fixed on seat ring the guide plate suitable with this guide surface.
Compared with the prior art, the utility model, owing to having adopted said structure, organically combines worm-drive and lead screw transmission, even if therefore bearing roller because wearing and tearing produce larger gap, also can regulate roller clearance by adjusting the position of bearing outer ring; Also can utilize the latching characteristics of worm-drive, lead screw transmission to carry out spacing to the position of bearing outer ring simultaneously; Both improve the dimensional accuracy of rolling plate, thereby extended again the frequency that has reduced the maintenance that stops production service life of taper roll bearing.The utlity model has simple in structure, the advantage such as bearing clearance is easy to adjust, degree of regulation is accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view in Fig. 1.
In figure: regulating sleeve 1, guide plate 2, taper roll bearing 3, roll 4, bearing block 5, lead screw shaft 6, worm screw 7, seat ring 8, worm gear 9, feather key 10.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1～2: seat ring 8 is fixed by screws on bearing block 3, the left end of lead screw shaft 6 is bearing in seat ring 8 by bearing, has the regulating sleeve 1 coordinating with it by internal thread in lead screw shaft 6; In lead screw shaft 6, there is the worm gear 9 being connected as a single entity with it, be bearing in seat ring 8 by bearing with the worm screw 7 of this worm gear engagement; Between regulating sleeve 1 and seat ring 8, there is the guiding mechanism that prevents that regulating sleeve 1 from rotating.
Described guiding mechanism both can by be opened in regulating sleeve 1 outer wall gathering sill, form with suitable feather key 10 or the guide finger (not shown) of this gathering sill; Also can by be located at regulating sleeve 1 outer wall guide surface, be fixed on seat ring 8 guide plate 2 suitable with this guide surface and form.
Operation principle: roll 4 is bearing on bearing block 5 by taper roll bearing, when the roller of taper roll bearing produces loosening and while there is excesssive gap, only need rotary worm 7 to drive lead screw shaft 6 to rotate by worm gear 9, regulating sleeve 1 stretches out under the effect of feather key 10 or guide plate 2 from seat ring 8, so the outer ring of taper roll bearing 3 moves right under the effect of regulating sleeve 1, thereby the roller clearance of taper roll bearing 3 is turned down.
Claims (3)
1. a roll bearing slack adjuster, is characterized in that: the regulating sleeve (1) that comprise the seat ring (8) that is fixed on bearing block (5), be bearing in lead screw shaft in this seat ring (6), coordinates by internal thread with this lead screw shaft, be fixed on worm gear (9) in this lead screw shaft, and the worm screw (7) of this worm gear engagement and be positioned at regulating sleeve (1) and seat ring (8) between guiding mechanism.
2. roll bearing slack adjuster according to claim 1, is characterized in that: the outer wall of regulating sleeve (1) has gathering sill, and described guiding mechanism forms with the suitable feather key (10) of this gathering sill or guide finger in being fixed on seat ring (8).
3. roll bearing slack adjuster according to claim 1, is characterized in that: the outer wall of regulating sleeve (1) has guide surface, and described guiding mechanism forms by being fixed on the guide plate (2) that seat ring (8) is upper and this guide surface is suitable.
