utility model 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 mechanism, it arranges groove on the outer face of jam nut, groove circumference arranges teeth groove, pad is arranged in groove, the excircle of pad is provided with sawtooth, sawtooth and teeth groove cooperatively interact, and by adjusting the correspondence position of sawtooth and teeth groove, realize the adjustment to bearing clearance, Adjustment precision is high, jam nut end face arranges push bolt simultaneously, by push bolt compact lock jack panel and pad, prevents pad rotation.
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 locking mechanism, wherein: comprise central siphon, jam nut, pad and bearing, bearing carrier ring is contained in the middle part of central siphon, central siphon termination is provided with jam nut, jam nut compresses bearing face, the outer face of described jam nut is provided with groove, groove circumference arranges teeth groove, pad is arranged in groove, the excircle of pad is provided with sawtooth, sawtooth and teeth groove cooperatively interact, and the end face of described jam nut is provided with push bolt, push bolt compact lock jack panel and pad.
Further, described central siphon is provided with draw-in groove, the inner periphery of pad is provided with fixture block, and fixture block sticks in draw-in groove.
Further, described push bolt adopt stud bolt or between push bolt and jam nut end face on large pad is set.
The beneficial effects of the utility model are:
1, the utility model arranges groove on the outer face of jam nut, groove circumference arranges teeth groove, pad is arranged in groove, and the excircle of pad is provided with sawtooth, and sawtooth and teeth groove cooperatively interact, by adjusting the correspondence position of sawtooth and teeth groove, realize the adjustment to bearing clearance, Adjustment precision is high, and jam nut end face arranges push bolt simultaneously, by push bolt compact lock jack panel and pad, prevent pad rotation.
2, the utility model structure is simple, easy to use, cost is low, simple and reliable, the adjustment of bearing clearance can be realized by actv., improve the Adjustment precision of bearing clearance, the preload of bearing is accurately controlled in claimed range, to ensure the service life of bearing.
accompanying drawing illustrates:
Fig. 1 is existing automotive axle hub bearing adjustment locking mechanism schematic diagram;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is that schematic diagram is looked on a left side of the utility model Fig. 2;
Fig. 4 is the A portion enlarged diagram of the utility model Fig. 3;
Fig. 5 is the structural representation of jam nut of the present utility model;
Fig. 6 is the structural representation of pad of the present utility model.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Fig. 6, a kind of axle hub bearing 4 adjusts locking mechanism, comprise central siphon 1, jam nut 2, pad 3 and bearing 4, bearing 4 is sleeved in the middle part of central siphon 1, central siphon 1 termination is provided with jam nut 2, jam nut 2 compresses bearing 4 end face, the outer face of described jam nut 2 is provided with groove 5, groove 5 circumference arranges teeth groove 6, pad 3 is arranged in groove 5, the excircle of pad 3 is provided with sawtooth 7, sawtooth 7 and teeth groove 6 cooperatively interact, the end face of described jam nut 2 is provided with push bolt 10, push bolt 10 compact lock jack panel 2 and pad 3, central siphon 1 is provided with draw-in groove 8, the inner periphery of pad 3 is provided with fixture block 9, fixture block 9 sticks in draw-in groove 8, at push bolt 10, under sticking into fixture block 9 combined action in draw-in groove 8, pad 3 rotation can be prevented by actv., described push bolt 10 is stud bolt.
During use, by predetermincd tension requirement, jam nut 2 is tightened, jam nut 2 inner end surface compresses bearing 4, outer face pad 3 being put into jam nut 2 is provided with in groove 5, and the sawtooth 7 on pad 3 is cooperatively interacted with the teeth groove 6 in groove 5, meanwhile, the fixture block 9 on pad 3 sticks in the draw-in groove 8 of central siphon 1, finally, by push bolt 10 compact lock jack panel 2 and pad 3.
When needs adjustment bearing 4 play, unclamp push bolt 10, tighten slightly or unclamp slightly jam nut 2, until reach the requirement of bearing 4 play, then rotating gasket 3, makes the sawtooth 7 on pad 3 load in teeth groove 6, and fixture block 9 sticks in draw-in groove 8 simultaneously, finally lock push bolt 10, so far complete the adjustment of bearing 4 play.Because the quantity of sawtooth 7 and teeth groove 6 is a lot, the angle of each tooth is little, and improve Adjustment precision, the preload of bearing 4 accurately controls in claimed range, ensures bearing 4 service life.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
