Abstract
The utility model relates to stepless adjusting washers for adjusting and locking an axle hub bearing. Each stepless adjusting washer adopts a circular ring structure, long holes are uniformly distributed in the stepless adjusting washer, a fixture block is arranged on the inner circumference of the circular ring structure, and the long holes can cover the whole circumference after two stepless adjusting washers are assembled forwards and reversely. According to the stepless adjusting washers for adjusting and locking the axle hub bearing, round holes uniformly distributed in each adjusting washer are designed into the long holes, and the long holes can cover the whole circumference when the adjusting washers are assembled forwards and reversely, so that the mounting position of a fastening screw can be adjusted at any angle, and stepless adjustment for a bearing clearance is achieved; and each stepless adjusting washer is simple in structure, convenient to use, low in manufacturing cost, simple and reliable and can effectively realize stepless adjustment for the bearing clearance, and the pre-tightening degree of a bearing is controlled in a required range accurately, so that the service life of the bearing is guaranteed.
Description
technical field:
The utility model relates to axle hub bearing locking structure technical field, is specifically related to the stepless adjustment packing ring of a kind of axle hub bearing adjustment locking.
background technique:
As shown in Figure 1, the adjustment locking mechanism of existing passenger vehicle vehicle bridge hub bearing, is made up of anti-attrition back-up ring 101, locking nut 102, adjustment packing ring 103, set screw 104.Wherein wear-resisting effect, through heat treatment, is played in anti-attrition back-up ring 101 inner sides; Locking nut 102 works back-up ring, the bearing effect of compressing; Adjust packing ring 103 and work the bearing clearance effect of adjusting; Set screw 104 is fastened on adjustment packing ring 103 on locking nut 102, rises to stop and adjusts packing ring 103 rotary actions, circumferential uniform two interior threaded holes of locking nut 102, circumferential uniform several circular holes of adjustment packing ring 103; Set screw 104 is through the circular hole of adjusting on packing ring 103, then tighten in the interior threaded hole of locking nut 102, on locking nut 102, be provided with locking slot, adjust on packing ring 103 inner circumferences and be provided with fixture block 105, fixture block 105 sticks in locking slot, the difference of the circular hole installing by adjustment set screw 104, reaches the effect of adjusting bearing clearance.
As shown in Figure 2, be the structural representation of existing general adjustment packing ring 103, generally formed by the thick steel plate punched of 4mm, circumferentially uniform several circular holes, by rotating or instead filling, can realize certain grade adjustment that has, to ensure, hub bearing is tightened in certain limit in advance.The problem of its existence has: 1) can only realize level adjustment, can not realize accurate adjustment, because the pre-tightness of bearing is very large on its life-span impact, therefore, may affect bearing life; 2), if wheel hub is bearing unit structure, because the pretightening force requiring is large, very difficult when adjustment, raw factory efficiency is low.
model utility content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of axle hub bearing adjustment locking stepless adjustment packing ring, it is to be designed to slotted hole by adjusting uniform circular hole on packing ring, and when positive and negative equipment adjustment packing ring, slotted hole can cover whole circumference, thereby the mounting point that can realize arbitrarily angled adjustment set screw reaches the object of the whole bearing clearance of stepless-adjustment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of axle hub bearing adjustment stepless adjustment packing ring for locking, wherein: described stepless adjustment packing ring is circle structure, is evenly distributed with slotted hole, and is provided with fixture block on the inner circumference of circle structure on it, and by after the positive and negative assembling of two stepless adjustment packing rings, slotted hole can cover whole circumference.
Further, on described stepless adjustment packing ring, be evenly distributed with 12 slotted holes.
The beneficial effects of the utility model are:
1, the utility model is to be designed to slotted hole by adjusting uniform circular hole on packing ring, and when positive and negative equipment adjustment packing ring, slotted hole can cover whole circumference, thereby the mounting point that can realize arbitrarily angled adjustment set screw reaches the object of the whole bearing clearance of stepless-adjustment.
2, the utility model is simple in structure, easy to use, cost is low, simple and reliable, can effectively realize the stepless adjustment of bearing clearance, the pre-tightness of bearing is accurately controlled in claimed range, to ensure the working life of bearing.
brief description of the drawings:
Fig. 1 is that existing automotive axle hub bearing is adjusted locking mechanism schematic diagram;
Fig. 2 is the structural representation of existing adjustment packing ring;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the schematic rear view of the utility model Fig. 3;
Fig. 5 is the utility model Fig. 3, Fig. 4 schematic diagram after overlapping.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 3, Fig. 4, Fig. 5, a kind of axle hub bearing adjustment stepless adjustment packing ring for locking, described stepless adjustment packing ring 201 is circle structure, on it, be evenly distributed with 12 slotted holes 202, and on the inner circumference of circle structure, be provided with fixture block 203, and by after the positive and negative assembling of two stepless adjustment packing rings 201, slotted hole 202 can cover whole circumference.
When use, by pretightening force requirement, locking nut 102 is tightened, adjustment packing ring 103 is loaded onto, if slotted hole 202, with locking nut 102 upper screwed holes not at once, turns over turnback by stepless adjustment packing ring 201 on it, then fastening with set screw 104, simple and reliable, obviously improving production efficiency.
Be noted that, above-described embodiment is explanation to technical solutions of the utility model and unrestricted, other amendment that is equal to replacement or makes according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, within all should being included in the desired interest field of the utility model.
