Description
Technical field
The present invention relates to a kind of roller bearings of four point contact of technical field of bearings more particularly to biserial.
Background technology
Traditional roller bearing conventional structure is by the full needle roller structure of thick cup needle roller bearings and bolt combination, the spiral shell of bearing
Oil leab is provided in bolt, due to dosing lubricating grease for full needle roller structure and needs outside, current traditional idler wheel
Bearing is suitable for some running accuracies and requires low, low, some operating modes of severe load of rotating speed requirement, in use also often
There is the problems such as leakage of some internal lubrication fat, external contaminants invasion and troublesome maintenance.
The present invention be exactly in order to solve problem above and carry out improvement.
Invention content
The object of the present invention is to provide a kind of four point contact roller bearings of biserial, to solve the defect of the prior art.
The present invention is technical solution used by solving its technical problem：
A kind of four point contact roller bearing of biserial, including roller bearing outer ring, roller bearing inner ring and steel ball, the steel ball
In raceway between roller bearing outer ring and roller bearing inner ring, there is lubricating grease in raceway face shape between raceway and steel ball
At lubricating oil film, retainer is installed on the outside of the steel ball, the outside of the retainer is equipped with sealing ring, it is characterised in that：
The raceway two arranges, and shape is combined by the identical arc groove of corresponding shape on the roller bearing outer ring and roller bearing inner ring
At the groove is in two-point contact with the steel ball, and the raceway is in four point contacts with the steel ball.
The lubricating grease uses molybdenum disulfide.
The sealing ring is made of rigid backbone and flexible lip, and the rigid backbone is coated on inside flexible lip, described close
Seal one end is supported and fixed in the groove on the inner wall of roller bearing outer ring, and the other end passes through in the flexible lip and roller bearing
Ring outer wall is in interference fit.
The roller bearing outer peripheral surface is spherical structure, and radius is
R254mm~R508mm.
The advantage of the invention is that：
1. four point contact roller bearing of a kind of biserial proposed by the present invention uses the hermetically sealed design of pre-fill lubricating grease, steel ball to connect
The form of touching uses four point contact structures,
2. the roller bearing structure novel, installation and debugging are convenient and non-maintaining, are suitable for common load, running accuracy requirement
High operating mode.
Description of the drawings
Fig. 1 is a kind of sectional view of four point contact roller bearing of biserial proposed by the present invention；
Fig. 2 is the sectional view of raceway and steel ball in the roller bearing；
Fig. 3 is the structural schematic diagram of sealing ring in the roller bearing.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Diagram and specific embodiment are closed, the present invention is further explained.
As shown in Figure 1 to Figure 3, four point contact roller bearing of a kind of biserial proposed by the present invention, including roller bearing outer ring
1, roller bearing inner ring 2 and steel ball 4, steel ball are set in the raceway 3 between roller bearing outer ring 1 and roller bearing inner ring 2, raceway
There is lubricating grease to form lubricating oil film on 4 surface of raceway between 3 and steel ball 4, the outside of steel ball 3 is installed with retainer 5, retainer 5
Outside be equipped with sealing ring 6, raceway 4 has two row, identical with corresponding shape on roller bearing inner ring 2 by roller bearing outer ring 1
Arc groove 11 and the combination of arc groove 22 formed, groove 11,22 and steel ball 3 are in two-point contact, and raceway 4 is in four with steel ball 3
Point contact.This not only reduces the contacts area of steel ball 4 and raceway to also add gap, convenient to dose lubricating grease in advance.
Lubricating grease uses molybdenum disulfide, molybdenum disulfide to have the function of shock resistance, non-maintaining as additive.
Sealing ring 6 is made of rigid backbone 61 and flexible lip 62, and rigid backbone 61 is coated on inside flexible lip 62, sealing ring
6 one end are supported and fixed in the groove on the inner wall of roller bearing outer ring, and the other end passes through outside flexible lip 62 and roller bearing inner ring
Wall is in interference fit.
Roller bearing outer peripheral surface is spherical structure, and radius is R254mm~R508mm.
Embodiment of above only technical concepts and features to illustrate the invention, its object is to allow those skilled in the art
Member understands present disclosure and is implemented, and it is not intended to limit the scope of the present invention, all according to spirit of that invention
The equivalent change or modification that essence is done should all cover within the scope of the present invention.
