Description
Technical field
This utility model belongs to bearing mnanufacture technical field, is specifically related to a kind of cylindrical roller thrust bearing.
Background technology
Cylindrical roller thrust bearing, for bearing heavier axial load, is used in the engineering machinery such as automobile.Thrust circle
Post roller bearing is typically made up of the assembly of blowout patche, seat ring, retainer and roller, and three the most separable.Heavier in order to bear
Load, the rolling element size of cylindrical roller thrust bearing is very big, and length is the longest so that the linear velocity at roller two ends in operation process
Difference strengthens, and causes abrasion, affects bearing operation, reduces the service life of bearing.The holding of common cylindrical roller thrust bearing
Frame, without guiding, causes retainer axial float, makes bearing operation unstable, and lubrication is not smooth, rubs bigger.
Summary of the invention
The defect existed for current technology, the purpose of this utility model be to provide for a kind of smooth running, lubrication fully,
Frictional force is little such that it is able to improve the sealed double-row self-lubricating cylindrical roller thrust bearing unit in the service life of bearing.
For achieving the above object, the technical solution that this utility model is used is: a kind of sealed double-row self-lubricating pushes away
Power cylinder roller bearing unit, including seat ring, blowout patche, roller and retainer, the biserial rolling that roller is and is emitted in retainer
Son, it is characterised in that: described retainer is nylon cages；Nylon cages is provided with semicircle oil-way；Seat ring with
The end of blowout patche is provided with sealing cover；Blowout patche medial surface is provided with blowout patche seal groove and double-lip sealing ring；Seat ring medial surface is provided with
Seat seal groove and double-lip sealing ring；Nylon cages, double-lip sealing ring are formed with seat seal groove and blowout patche seal groove and seal.
On the face that nylon cages described in technical solution of the present utility model is adjacent with seat ring and blowout patche respectively
It is provided with the semicircle oil-way of arranged side by side two.
One end of sealing cover described in technical solution of the present utility model coordinates with the taper surface of blowout patche, another
End coordinates with the trough with straight angle of seat ring.
This utility model compared with prior art, owing to being provided with sealing cover in the end of seat ring Yu blowout patche, at nylon
Retainer is provided with semicircle oil-way, is provided with blowout patche seal groove and double-lip sealing ring at blowout patche medial surface, inside seat ring
Face is provided with seat seal groove and double-lip sealing ring, thus available sealing cover locks seat ring and blowout patche, makes nylon cages, lips
Sealing ring is formed with seat seal groove and blowout patche seal groove and seals, and makes to form sufficient lubricating oil film at guide surface, reduces friction,
Improve bearing life.This utility model has smooth running, lubrication is abundant, frictional force is little and improves the spy in bearing service life
Point.This utility model is mainly used in cylindrical roller thrust bearing.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Reference in Fig. 1 is as follows: 1, seat ring, 2, blowout patche, 3, roller, 4, nylon cages, 5, double-lip sealing ring, 6,
Sealing cover, 4-1, semicircle oil-way, 1-1, seat seal groove, 2-1, blowout patche seal groove.
Detailed description of the invention
Elaborate below in conjunction with the accompanying drawings and to this utility model.
As shown in Figure 1.This utility model sealed double-row self-lubricating cylindrical roller thrust bearing unit includes seat ring 1, blowout patche
2, roller 3 and retainer, the biserial roller that roller 3 is and is emitted in retainer.Retainer is nylon cages 4, two row rollings
Son 3 is emitted in nylon cages 4, and nylon cages 4 coordinates installation, roller 3 and nylon cages 4 composition one with roller 3,
It is placed between seat ring 1 and blowout patche 2.Seat ring 1 is provided with sealing cover 6, one end of sealing cover 6 and blowout patche 2 with the end of blowout patche 2
Taper surface coordinate, the other end coordinates with the trough with straight angle of seat ring 1, is locked with blowout patche 2 by seat ring 1 with sealing cover 6.Nylon keeps
The face that frame 4 is adjacent with seat ring 1 is provided with arranged side by side two semicircle oil-way 4-1, and nylon cages 4 is adjacent with blowout patche 2
It also is provided with the semicircle oil-way of arranged side by side two, sufficient lubrication on face, makes at guide surface, to form sufficient lubricating oil film, reduce
Friction, can improve bearing life.Outside blowout patche 2 axle, medial surface is provided with blowout patche seal groove 2-1 and double-lip sealing ring 5, outside seat ring 1 axle
Side medial surface is provided with seat seal groove 1-1 and double-lip sealing ring 5.Nylon cages 4, double-lip sealing ring 5 and seat seal groove 1-1
And blowout patche seal groove 2-1 is formed and seals.
