Description
Technical field
It the utility model is related to technical field of automobile parts, and in particular to roll to a kind of cylinder for truck drive shaft
Sub- bearing.
Background technology
Bearing is to be used to determine rotation axis and other parts relative motion position, plays the parts of supporting or guiding role.
The major function of bearing is supporting rotating shaft or other movable bodies, guides rotation or moving movement and bears by axis or parts on shaft
The load being transmitted to.
Bearing is to start to step into the arena of history with the appearance of human industry's civilization.16th century, west start to rise
The industrial revolution, to 18th century mid-term, bearing starts to occur as independent mechanical organ.To earlier 1900s, bearing
Technology enters modern development period, has initially formed bearing industry in large scale.Into 21st century, bearing has been to work as
For base parts and components indispensable in mechanical equipment, in national economy every profession and trade using quite varied, its precision, performance,
Life and reliability plays conclusive effect to the precision, performance, life and reliability of host.
Although current bearing disclosure satisfy that mechanically operated requirement in precision, bearing at work often by
To radial and axial impact force, axial impact force can will not change the transmission accuracy of bearing by the displacement buffering of axis,
But radial impact force can aggravate the abrasion of bearing, so as to influence transmission accuracy.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned problem, there is provided it is a kind of simple in structure, it is easy to make, and can have
There is higher anti-radial impact force, the abrasion of bearing can be reduced, while can also conveniently repair being used for for replacement even if abrasion
The cylinder roller bearing of truck drive shaft.
The purpose of this utility model is realized and is made of following aspect：
For the cylinder roller bearing of truck drive shaft, include outer ring and the inner ring of bearing, and installed in both it
Between retainer, it is characterised in that：The inner wall of the outer ring is provided with a dismountable lasso, lasso inner wall circumferentially one
It is provided with the protrusion of several dome-types week, all raised close contact arrangements do not interspace each other, and raised half
Footpath is identical with the diameter of cylindrical roller；Be provided with several cylindrical rollers on the retainer, the number of cylindrical roller with it is convex
The number risen is identical, and each cylindrical roller is stuck at the space between two protrusions；The outer surface of the inner ring with
The intimate surface contact of cylindrical roller.
In such scheme, the retainer is stationary structure, and retainer circumference offers several installations in one week
Hole, the number of mounting hole is identical with cylindrical roller, and 1.2-1.5 times that the width of mounting hole is cylindrical roller diameter.
In such scheme, compression installation is carried out using interference fit between the outer ring and lasso, and in outer ring and
One layer of fluid sealant is scribbled at the combination gap of lasso.
In such scheme, the centre of the cylindrical roller is provided with the waist of indent, and waist is arc concave shape, and with
Raised outer surface is in close contact.
The beneficial effects of the utility model are：
The utility model is simple in structure, easy to make, can have higher anti-radial impact force, can reduce bearing
Abrasion, while can also conveniently maintenance be replaced even if abrasion, improve the service life of bearing.
Brief description of the drawings
Fig. 1 is the utility model embodiment structure chart；
In figure:1 outer ring, 2 inner rings, 3 retainers, 4 lassos, 5 raised, 6 cylindrical rollers.
