Abstract
A hub fixing structure free of bearing clearance tuning comprises two conical roller bearings which are arranged back to back are installed in a hub, an outer circle of each bearing is located through a stopping shoulder arranged on each side of the hub, each inner circle of each bearing is respectively located through a shaft shoulder of a shaft head and a bearing locking nut, a separating sleeve is sleeved on each shaft head, each shaft sleeve is arranged between the inner circle of one bearing, and the inner circle of one bearing abuts against two ends of each separating sleeve. According to the hub fixing structure free of tuning the bearing clearance, the bearing clearance is guaranteed by means of the length of each separating sleeve and the distance between the two stopping shoulders of the hub, and just the bearing locking nuts need to be screwed tightly when the hub is assembled, so that manual adjusting the tightening torque of the locking nut and motions of unscrewing of the nut after the nut is tightly screwed are eliminated. The hub fixing structure free of tuning the bearing clearance is convenient to operate, and beneficial to prolonging the service life of bearings.
Description
Technical field
The utility model relates to the axletree of automobile and the connection structure between the wheel hub.
Background technology
In some automobiles, superimposed trailer for example, the connection structure between its wheel hub and the axletree has adopted the tapered roller bearing of two back-to-back arrangements, to bear bi-directional axial load.At present, the outer ring of the tapered roller bearing in this type of wheel hub fixed sturcture is by the shoulder block location of wheel hub, bearing inner ring by spindle nose the shaft shoulder and bearing lock nut come fastening, the end-play of bearing by the screw-down torque of controlling bearing lock nut and the anti-loose angle after tightening control.The shortcoming of this structure is that size and the anti-loose angle of screw-down torque is difficult definite, need repeatedly adjust screw-down torque and anti-loose angle and detect end-play just can reach requirement.And maintenance is inconvenient, and the anti-loose angle of user when bearing lock nut is installed is wayward, causes easily because of the improper bearing problem in service life that reduces of bearing clearance adjustment.
The utility model content
The purpose of this utility model provides a kind of wheel hub fixed sturcture of exempting to transfer bearing clearance.
The utility model is achieved in that the wheel hub fixed sturcture of exempting to transfer bearing clearance, comprise the tapered roller bearing that is installed in two back-to-back arrangements in the wheel hub, locate by the both sides shoulder block of wheel hub respectively the outer ring of two bearings, the inner ring of two bearings is located by the shaft shoulder and the bearing lock nut of spindle nose respectively, be with spacer at spindle nose, spacer is between the two bearings inner ring, and the two bearings inner ring leans the two ends at spacer.
The utility model guarantees bearing clearance by the length of spacer and the distance of wheel hub two shoulder blocks, and the distance of the length of spacer and wheel hub two shoulder blocks, just definite in processing spacer and wheel hub, therefore when the assembling wheel hub, only need bearing lock nut is tightened, just can guarantee the end-play of bearing, the action of having saved the screw-down torque of artificial adjustment jam nut and having tightened the anti-loose nut in back, easy to operate, and be conducive to prolong bearing service life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, according to a kind of wheel hub fixed sturcture of exempting to transfer bearing clearance that the utility model provides, comprise the tapered roller bearing 2,3 that is installed in two back-to-back arrangements in the wheel hub 1.Two bearings 2,3 outer ring 4,5 lean respectively on the both sides of wheel hub 1 shoulder block 6,7, by both sides shoulder block 6,7 location.Two bearings 2,3 inner ring 8,9 lean respectively on the shaft shoulder 10 and bearing lock nut 11 of spindle nose, by the shaft shoulder 10 and jam nut 11 location.Be with spacer 12 at spindle nose, spacer 12 is between two bearings inner ring 8,9, and two bearings inner ring 8,9 leans the two ends at spacer 12.
Distance between the both sides shoulder block 6,7 of wheel hub 1 is A, and the length of spacer 12 is B, when processing wheel hub 1 and spacer 12, determines size value and the tolerance value of A, B according to required bearing clearance.During running in bearings, only need bearing lock nut 11 is tightened, the inner ring 8,9 of two bearings is leaned at the two ends of spacer 12, the two bearings 2 after just guaranteeing to assemble, 3 play adhere to specification.
As another kind of embodiment of the present utility model, can also between the inner ring 8,9 of spacer 12 and bearing, packing ring be set, to remedy the Mismachining tolerance of wheel hub 1 and spacer 12.Bring certain trouble can for the assembling of bearing though set up packing ring, the end-play of bearing still need not to rely on the screw-down torque of adjusting bearing lock nut 11 and tighten after anti-loose angle control, therefore remain like this and exempt to transfer bearing clearance.
Claims (1)
1. exempt to transfer the wheel hub fixed sturcture of bearing clearance, comprise the tapered roller bearing (2,3) that is installed in two back-to-back arrangements in the wheel hub (1), locate by the both sides shoulder block (6,7) of wheel hub (1) respectively the outer ring of two bearings (4,5), the inner ring of two bearings (8,9) is located by the shaft shoulder (10) and the bearing lock nut (11) of spindle nose respectively, it is characterized in that: be with spacer (12) at spindle nose, spacer (12) is positioned between the described two bearings inner ring (8,9), and two bearings inner ring (8,9) leans the two ends in spacer (12).
