Abstract
The utility model relates to a hub mechanism, in particular to a hub provided with an adjusting nut for a bearing, in order to mainly solve the technical problems that the existing hub is incapable of securely locking the outer end of a drive shaft and has the disadvantages of narrower adjustment range on hubs of various models and complicated assembly in the prior art. The hub of the utility model comprises a hub (1), wherein a half shaft (2) is arranged in the hub; the hub is characterized in that the adjusting nut (3) is sheathed on the outer end of the half shaft (2); a through groove (4) is formed in the radial direction of the adjusting nut; a screw hole (5) penetrates through the through groove; the center line of the screw hole is perpendicular to that of the adjusting nut; and a lock nut (6) is threaded in the screw hole (6).
Description
Technical field
The utility model relates to a kind of hub mechanism, especially relates to the wheel hub that a kind of tape spool holds adjustment nut.
Background technology
At present, known wheel hub structure is by wheel hub, sleeve pipe, adjustment nut, retaining washer, jam nut be connected wheel hub and two tapered roller bearings of sleeve pipe are formed.Chinese patent discloses a kind of hub-bearing unit (Granted publication number: CN 200984943Y) of nut locking, it comprises outer cover, flange, be connected with the wheel hub inner ring on the step of flange neck, the inner ring periphery is connected with the wheel hub outer ring, be provided with rolling body between inner ring and flange neck step place and the outer ring, the inboard, outer ring is provided with the double channel of symmetry, the contact surface in its cross section has the arc surface suitable with rolling body, be located at the non-leading end face of outer ring outward, it is inboard directly relative with the nut that is located at the inner ring large end face and lock with the flange neck, it and nut, inner ring large end face and flange neck end form chamber, the axle journal place of flange is provided with screw thread, nut is screw thread fit therewith, and nut contacts with the inner ring large end face, rolling body is by the retainer captive joint, and retainer passes the center of gravity of rolling body, and the wheel hub cycle surface is provided with some threaded shank hole.Chinese patent also discloses a kind of commercial vehicle/comm..vehicle or passenger vehicle drive axle, and (Granted publication number: CN 201144966Y), it is made up of semiaxis, axle-shaft oil seal, hub bearing, axle housing spindle nose, wheel hub, double oil seal, " 0 " shape seal ring, trivial, jam nut, back-up ring with inner chamber band radiating ribs thin oil lubricant formula hub shell; In drive axle hub shell inner chamber, cast 2-4 radiating ribs, the gradient of radiating ribs is the 40-60 degree.But these two kinds of wheel hubs are more insecure to the locking of transmission shaft outer end, and less for the wheel hub setting range of different model, assemble comparatively numerous and diverse.
The utility model content
The utility model provides the wheel hub that a kind of tape spool holds adjustment nut, and it mainly is that solution existing in prior technology wheel hub is more insecure to the locking of semiaxis outer end, and less for the wheel hub setting range of different model, the technical matters of the comparatively numerous and diverse grade of assembling.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
Tape spool of the present utility model holds the wheel hub of adjustment nut, comprise wheel hub, be provided with semiaxis in the wheel hub, the outer end of described semiaxis is socketed with adjustment nut, adjustment nut is having groove in the radial direction, the groove place is penetrated with screw, and center line of bolt hole is vertical with the adjustment nut line of centers, and cross-under has black nut in the screw.Owing to have a groove, so it can be according to its diameter of big minor adjustment of semiaxis on the adjustment nut, adjusts and can groove be sealed by the cross-under black nut after finishing, thereby realized purpose with the transmission shaft locking.Semiaxis can be notch cuttype, is convenient to like this install, and the outer end of adjustment nut can be provided with dust shroud, can prevent dust intrusion wheel hub inside like this.
As preferably, be provided with neck bearing and outer bearing between described wheel hub and the semiaxis.Neck bearing and outer bearing are oppositely arranged, can be so that the rotation of wheel hub.
As preferably, described adjustment nut the inner is provided with pad, and the width of adjustment nut groove is 2～6mm.The width of adjustment nut groove with and external diameter can be according to the big minor adjustment of whole wheel hub.
Therefore, the utility model is opened groove at the adjustment nut place, by black nut groove is sealed, and is comparatively firm to the locking of transmission shaft outer end, and goes for the wheel hub of different model, and setting range is bigger, assembles more or less freely, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structural representations of adjustment nut in the utility model.
Parts, position and numbering among the figure: wheel hub 1, semiaxis 2, adjustment nut 3, groove 4, screw 5, black nut 6, neck bearing 7, outer bearing 8, pad 9, dust shroud 10.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: this routine tape spool holds the wheel hub of adjustment nut, as Fig. 1, a wheel hub 1 is arranged, and is provided with semiaxis 2 in the wheel hub, and the diameter of semiaxis reduces from inside to outside successively, is respectively equipped with neck bearing 7, outer bearing 8 between semiaxis and the wheel hub inside face.The outer end of semiaxis is provided with adjustment nut 3, having groove 4 in the radial direction as Fig. 2 adjustment nut, the width of groove is 4mm, the groove place is penetrated with screw 5, center line of bolt hole is vertical with the adjustment nut line of centers, and cross-under has black nut 6 in the screw, and the inner of adjustment nut is provided with pad 9, the outer end of adjustment nut is provided with dust shroud 10, and dust shroud is connected on the wheel hub 1 by screw.
During use, adjustment nut 3 is socketed in the semiaxis outer end, at screw 5 places cross-under black nut 6 the groove locking is got final product then.
The above only is a specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
