Abstract
The drive axle hub being easily installed, it is related to automotive hub technical field；It includes knuckle, oil sealing, clutch shaft bearing, hub body, second bearing, cover plate, screw；Described knuckle is connected with hub body, and oil sealing is provided between knuckle and hub body, and the side of oil sealing is provided with clutch shaft bearing, and the side of clutch shaft bearing is provided with second bearing, and one end of knuckle has been connected by screw cover plate.The drive axle hub being easily installed described in the utility model, compared with the installation of prior art, Personal Skills to workman require to reduce, while efficiency of assembling and quality are greatly improved, the utility model has the advantages that simple structure, sets reasonable, low manufacture cost.
Description
Technical field
The utility model is related to automotive hub technical field, and in particular to the drive axle hub being easily installed.
Background technology
It is to reach certain bearing clearance or pretension load, taper roll bearing during assembling that end-play is adjusted axially
All can adjust to play its optimal performance.Taper roll bearing end-play levels off to zero life-span close to most long.Initial group
Dress and regulation obtained by end-play be at normal temperatures, bearing devote oneself to work before set.The end-play of gained during work
It is referred to as work end-play.Because working condition issues heat expansion and bent by load, there is normal temperature end-play
Change.Best effort end-play is different with use environment and sets normal temperature end-play and change.Application experience or test
Best effort end-play can generally be determined.
The method for adjusting normal temperature end-play：1. applied probability principle, end-play size is by each part dimension of bearing
Radial and axial allowance control；2. under conditions of force is set, completed by measuring the axial dimension of pad or spacer ring.So
Afterwards, correct pad or spacer ring size are obtained from pre-prepd chart or reading measured directly.This method was both adapted to
The regulation of end-play, is adapted to being adjusted axially for preload again；3. the torque needed for measurement lower-speed state lower bearing is rolled, determines
Whether end-play is suitable, no matter being finally adjusted axially preload or clearance, this method can be applicable.
If hub bearing can not correctly coordinate, bearing will be caused to run abnormal or break down, or even can damage whole
Wheel hub.If bearing pre-fastening adjustment is improper, bearing axial play is increased generation impulsive force can make bearing damage；And if axle
Hold and be hardly formed complete oil film between end-play reduction, bearing roller, its scaling loss will be caused.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of simple structure, design are closed
Reason, the drive axle hub being easily installed easy to use.
To achieve the above object, the technical solution adopted in the utility model is：It comprising knuckle, oil sealing, clutch shaft bearing,
Hub body, second bearing, cover plate, screw；Described knuckle is connected with hub body, is set between knuckle and hub body
Oil sealing is equipped with, the side of oil sealing is provided with clutch shaft bearing, and the side of clutch shaft bearing is provided with second bearing, and one end of knuckle leads to
Crossing mode connects for screw has cover plate.
Preferably, the end-play value of described clutch shaft bearing and second bearing is 0~0.05mm.
Preferably, described oil sealing uses grease seal.
Preferably, width of the width of described second bearing more than clutch shaft bearing.
When the utility model is operated, in clutch shaft bearing and the surface smear butter of second bearing, as far as possible full of retainer and
The gap of roller；Cover plate is loaded onto, bolt is tightened；Because the amplitude of bearing life reduction is in the two directions different：Along negative
Clearance direction bearing service life reduction is obtained quickly, because temperature rise makes inner ring and rolls the negative value that volume expansion further increases clearance, axle
Holding the life-span can drastically reduce；Relatively will gently much along positive clearance direction bearing service life reduction.
After said structure, what the utility model was produced has the beneficial effect that：It is described in the utility model to be easily installed
Drive axle hub, compared with the installation of prior art, the Personal Skills to workman require to reduce, while efficiency of assembling and quality are big
Big to improve, the utility model has the advantages that simple structure, sets reasonable, low manufacture cost.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Description of reference numerals：
Knuckle 1, oil sealing 2, clutch shaft bearing 3, hub body 4, second bearing 5, cover plate 6, screw 7.
Specific embodiment
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Referring to as shown in figure 1, this specific embodiment is adopted the following technical scheme that：It includes knuckle 1, oil sealing 2, first
Bearing 3, hub body 4, second bearing 5, cover plate 6, screw 7；Described knuckle 1 is connected with hub body 4, knuckle 1 with
Oil sealing 2 is provided between hub body 4, the side of oil sealing 2 is provided with clutch shaft bearing 3, and the side of clutch shaft bearing 3 is provided with second
Bearing 5, one end of knuckle 1 is connected with cover plate 6 by screw 7.
Preferably, the end-play value of described clutch shaft bearing 3 and second bearing 5 is 0~0.05mm.
Preferably, described oil sealing 2 uses grease seal.
Preferably, width of the width of described second bearing 5 more than clutch shaft bearing 3.
When this specific embodiment is operated, in clutch shaft bearing 3 and the surface smear butter of second bearing 5, as far as possible full of guarantor
Hold the gap of frame and roller；Cover plate 6 is loaded onto, bolt 7 is tightened；Because the amplitude of bearing life reduction is in the two directions different
's：Obtained quickly along negative clearance direction bearing service life reduction, because temperature rise makes inner ring and rolling volume expansion further increase clearance
Negative value, bearing life can be drastically reduced；Relatively will gently much along positive clearance direction bearing service life reduction.
After said structure, what this specific embodiment was produced has the beneficial effect that：Described in this specific embodiment just
In the drive axle hub installed, compared with the installation of prior art, the Personal Skills to workman require to reduce, while efficiency of assembling
Greatly improved with quality, this specific embodiment has the advantages that simple structure, sets reasonable, low manufacture cost.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.This
The technical staff of industry is retouched in above-described embodiment and specification it should be appreciated that the utility model is not restricted to the described embodiments
That states simply illustrates principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model
Various changes and modifications are also had, these changes and improvements are both fallen within the range of claimed the utility model.This practicality is new
The claimed scope of type is by appending claims and its equivalent thereof.
