Description
Technical field
The utility model is related to a kind of bearing, specifically a kind of novel single-row cylinder roller bearing.
Background technology
With continuing to develop for industry, machinery industry also has bigger development prospect in every field, which results in
Demand to kinds of bearings is more diversified, and wherein single row roller bearing is applied again in the plant equipment at a high speed with big load
Extensively.General single row roller bearing includes bearing outer ring, bearing inner race, retainer and roller, installs very square with dismounting
Just, it can bear larger radial load.But, the universal rotating speed of single row roller bearing used by the country is relatively low at present, the longevity
Life is short, it is difficult to meet use requirement of the machinery in operation process, or even the damage such as beginning of fatigue failure occurs.
Utility model content
The purpose of this utility model is to provide a kind of novel single-row cylinder roller bearing, is rolled with solving existing single-row cylindrical
Relatively low and short life the problem of rotating speed present in sub- bearing.
What the utility model was realized in：A kind of novel single-row cylinder roller bearing, including in bearing outer ring, bearing
Circle, cylindrical roller and the retainer being arranged between the bearing outer ring and the bearing inner race, the bearing outer ring axial direction two
The inner ring surface at end is concordant with the inner ring surface of the bearing outer ring, and the outer ring surface at bearing inner race axial direction two ends is provided with inner ring
Rib, the inner ring rib is annular rib, and the inner ring rib and the bearing inner race are formed in one structure, the inner ring
Inclined-plane is set on the inside of rib；
The end face at the axial two ends of the bearing inner race is located at the inner side of the bearing outer ring corresponding end end face, in the guarantor
Hold and several are along the circumferential direction evenly arranged with frame use outer ring for accommodating the pocket hole of the cylindrical roller, the retainer
The Integral retainer of guiding.
The retainer outer ring surface corresponding to opening up fluted at the position between two pocket holes.
The retainer is copper cage.
The outer surface of the retainer is provided with plated silver finish.
The outer ring surface at the utility model middle (center) bearing inner ring axial direction two ends is provided with inner ring rib, and inner ring rib keeps off for annular
Side, inner ring rib and bearing inner race are formed in one structure, and inclined-plane, such cylindrical roller are set on the inside of the inner ring rib
End face and corresponding inner ring rib between can form wedge-shaped oil film, rubbing for roller and rib is reduced to a certain extent
Wipe, effectively increase the service life of bearing.The Integral retainer that retainer is guided using outer ring, and draw with lubricating oil entrance
Raceway where guide face and cylindrical roller, it is adaptable to the rotation speed operation high of bearing.
The rotating speed of single row roller bearing of the present utility model is improved compared with common single row roller bearing rotating speed
3 times, its service life improves more than 2 times, has fully met use requirement of the machinery in operation process.Additionally, this reality
P2 grades of highest micron order is can reach with new bearing accuracy grade, rotating speed high, low noise is made it have, is vibrated small, heating less
The advantage such as high with the life-span.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of novel single-row cylinder roller bearing, including bearing outer ring 1, bearing inner race 2,
Cylindrical roller 3 and the retainer 4 being arranged between bearing outer ring 1 and bearing inner race 2, the inner ring surface at the axial two ends of bearing outer ring 1
Inner ring surface with bearing outer ring 1 is concordant, and the outer ring surface at the axial two ends of bearing inner race 2 is provided with inner ring rib 5, inner ring rib 5
It is formed in one structure with bearing inner race 2.Inner ring rib 5 is annular rib, and the inner side of inner ring rib 5 is set to inclined-plane, at this
In embodiment, medial slope and the base angle of the ring raceway of bearing inner race formation of inner ring rib 5 are obtuse angle.In bearing inner race 2
Chamfering is provided with the inner ring surface and outer ring surface of end, is easy to the installation of bearing.The end face position at the axial two ends of bearing inner race 2
In the inner side of the corresponding end end face of bearing outer ring 1.
The inner ring of the Integral retainer 4 that retainer 4 is guided using outer ring, the i.e. outer ring surface of retainer 4 and bearing outer ring 1
Outer ring surface the distance between of the distance between the face less than inner ring surface and the inner ring rib 5 of retainer 4.Retainer 4 keeps for copper
Frame 4, plated silver finish is provided with the outer surface of retainer 4, and the intensity of copper cage is larger, is plated in the outer surface of copper cage
The human lymph node wearability and corrosion resistance of retainer 4, improves its self-lubricating capacities, and can effectively improve bearing rotating speed and
Service life.Several are along the circumferential direction evenly arranged with retainer 4 is used to accommodate the pocket hole of cylindrical roller 3, in this reality
Pocket hole is rectangle pocket hole in applying example.Pocket hole is one-to-one relation with cylindrical roller 3.In the correspondence of the outer ring surface of retainer 4
Fluted 6 are opened up at position between two pocket holes, this groove can both play lubrication, also can be to retainer lock pointing chisel print
Play positioning action.The two ends of cylindrical roller 3 are provided with circular arc convexity, the stress collection at rolling surface two ends can be prevented effectively from
In.The circular arc convexity of cylindrical roller 3 cooperatively forms wedge-shaped oil film with the medial slope of inner ring rib 5, can reduce roller with gear
The friction on side, effectively improves the life-span of bearing.
