Abstract
The utility model provides a kind of heavy truck and lengthens inner ring taper roll bearing, including outer ring（4）, roller（5）, inner ring（2）, described inner ring（2）Extend axially outward along small end face, described inner ring extension（6）Internal diameter be more than inner-ring bearing portion（7）Internal diameter.With efficiency of assembling is improved, the advantage of cost is reduced.
Description
Technical field
The utility model is related to a kind of taper roll bearing, and inner ring taper roller axle is lengthened especially with regard to a kind of heavy truck
Hold.
Background technology
Current heavy truck automobile hub bearing is formed a complete set of from two sets of taper roll bearings and spacer ring is mounted to profile unit,
This needs to be assembled according to the spacer ring of the often set high size selection corresponding size of bearing practical set, due to the assembling of single set bearing
High tolerance is larger, causes to select spacer ring size more after bearing pairing use, the reduction of hub efficiency of assembling.
The content of the invention
For deficiency of the prior art, the utility model aims to provide a kind of heavy truck for being not required to assemble spacer ring and lengthens inner ring
Taper roll bearing.
In order to solve the above problems, technical solution of the present utility model is：A kind of heavy truck lengthens inner ring taper roller
Bearing, including outer ring, roller, inner ring, described inner ring extend axially outward along small end face, the internal diameter of described inner ring extension
More than the internal diameter in inner-ring bearing portion.
The beneficial effects of the utility model are：Inner ring uses extension design, and adds meeting on working ability horizontal base
Tight bearing assembles high tolerance, due to cancelling center spacer during assembling, improves efficiency of assembling, reduces cost.
Brief description of the drawings
Fig. 1 is use schematic diagram of the utility model in the assembling of wheel hub；
Fig. 2 is inner ring structure schematic diagram of the present utility model.
In figure：1st, hollow shaft, 2, inner ring, 3, hub shell, 4, outer ring, 5, roller, 6, inner ring extension, 7, inner-ring bearing
Portion.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Heavy truck lengthens inner ring taper roll bearing, is made up of outer ring 4, roller 5, inner ring 2, and described inner ring 2 is along small end face
Extend axially outward, the internal diameter of described inner ring extension 6 is more than the internal diameter in inner-ring bearing portion 7, thus is avoided that because inner ring prolongs
The long heat treatment deformation of portion 6 causes to assemble interrupted during hollow shaft 1.
Identical two kinds of model taper roll bearing mounted in pairing mode are into hub in use, and this hub is main by hollow
Axle 1, two sets of same model taper roll bearings, housing 3 is constituted；Its tapered roller bearing internal ring 2 uses extension design, and full
Add tight bearing to assemble high tolerance on sufficient working ability horizontal base, can cancel the use of center spacer in assembling, improve dress
With efficiency.
Claims (1)
