Abstract
The invention relates to the field of manufacturing technology of rolling bearings, and discloses a sealed single-row cylindrical roller bearing which is formed by assembling a rolling body (3) and a retainer (4) which are arranged between an outer ring (2) and an inner ring (1), wherein two side end surfaces between the outer ring and the inner ring are in a sealing structure for sealing lubricating grease in the rolling body and the retainer; the sealing structure is fastened in sealing grooves arranged at two sides of the inner raceway of the outer ring (2) to be used for preventing the lubricating grease from being thrown away; and the sealing structure is in non-contact or light contact with the assembly structure of sealing ring pieces (5) arranged at two sides of the outer raceway of the inner ring (1) to be used for relieving the friction generated by the inner ring in the rotating process and preventing dust, cutting fluid and impurities from entering the rolling body (3) and the retainer (4). In the invention, the lubricating grease can be sealed in the bearing, thereby preventing the loss of the lubricating grease; the bearing has good sealing effect and low noise; and dust, cutting fluid and other impurities are prevented from entering the bearing, thereby prolonging the service life of the bearing.
Description
Technical field
The present invention relates to rolling bearing manufacturing technology field, relate in particular to a kind of sealing single row roller bearing.
Background technique
At present, single row roller bearing adopts the grease lubrication mode more.Because it is disposable lifelong lubricated that grease lubrication mostly is, and promptly when main frame is installed, to an amount of lubricating grease of the disposable adding of bearing, no longer adds lubricating grease in the main frame using process basically.Because the single row roller bearing of bearing manufacturer production is the open bearing of not being with sealing configuration, bearing inside easily enters dust, cutting fluid or throws away lubricating grease owing to bearing rotates in use, greatly reduce the greasy property of bearing, reduced the working life of bearing.
Summary of the invention
In order to overcome the open bearing of not being with sealing configuration, bearing inside easily enters dust, cutting fluid or rotates the defective that throws away lubricating grease owing to bearing in use, the invention provides a kind of sealing single row roller bearing, it is respond well to have bearing seal, noise is little, the characteristic of long working life.
For achieving the above object, the present invention adopts following technological scheme:
A kind of sealing single row roller bearing is made of rolling element between outer ring and the inner ring and retainer assembling, and the both sides end face between described outer ring and the inner ring adopts sealing configuration, is used for grease sealing in rolling element and retainer;
Described sealing configuration is fastened in the seal groove that the raceway both sides are provided with in the outer ring, is used to prevent that lubricating grease from throwing away;
The seal ring piece assembly structure non-contact that the outer raceway both sides of described sealing configuration and inner ring are provided with or gently contact is used for alleviating the friction that inner ring produces at rotary course, and prevention dust, cutting fluid and impurity enter rolling element and retainer inside.
The seal ring piece that the rubber structure that a kind of sealing single row roller bearing, described sealing configuration adopt band shape skeleton to support is made.
A kind of sealing single row roller bearing, the cylindrical roller that described rolling element adopts the Bearing Steel of high-quality to make, or the ceramic cylinder roller that adopts silicon nitride ceramics to make.
A kind of sealing single row roller bearing, described retainer adopts engineering plastics: PA66, PEEK, and make or adopt metal: copper or aluminium are made.
Owing to adopted technique scheme, the present invention to have following superiority:
A kind of sealing single row roller bearing because the bearing two ends have adopted sealing configuration, with grease sealing in bearing, prevent that lubricating grease runs off, good sealing effect, noise are low, have stoped dust, cutting fluid and other impurity to enter bearing inside, have prolonged the working life of bearing.Seal ring is with the inner ring non-contact or gently contact, and can guarantee has good sealing effect in the rotary course of bearing, and it is excessive to be unlikely to friction to occur again, produces thermal phenomenon.
Description of drawings
Fig. 1 is a kind of structural representation that seals the two ribs of single row roller bearing inner ring;
Fig. 2 is a kind of structural representation that seals the two ribs in single row roller bearing outer ring.
Among the figure: 1-inner ring; 2-outer ring; 3-rolling element; 4-retainer; 5-seal ring piece.
Embodiment
As shown in Figure 1 and Figure 2, a kind of sealing single row roller bearing, be made of rolling element 3 between outer ring 2 and the inner ring 1 and retainer 4 assemblings, the both sides end face between described outer ring 2 and the inner ring 1 adopts sealing configuration, is used for grease sealing in rolling element 3 and retainer 4;
Described sealing configuration is fastened in the seal groove that the raceway both sides are provided with in the outer ring 2, prevents that lubricating grease from throwing away; Seal ring piece 5 assembly structure non-contacts that described sealing configuration and inner ring 1 outer raceway both sides are provided with or gently contact are used for alleviating the friction that inner ring produces at rotary course; Stop dust, cutting fluid and impurity to enter rolling element 3 and retainer 4 inside;
During making, set up sealing configuration at the two ends of open type single row roller bearing, with grease sealing in bearing inside.Outer ring 2 has seal groove, and inner ring 1 has the seal ring piece assembly structure, and two seal ring pieces 5 are fastened on respectively in the seal groove of outer ring 2, and keeps slightly contacting or non-contact with inner ring 1.The seal ring piece 5 that the rubber structure that described sealing configuration adopts band shape skeleton to support is made, promptly seal ring piece 5 adopts rubber material, and the band skeleton supports.
This bearing inner race 1, outer ring 2 and rolling element 3 adopt the manufacturing of high-quality Bearing Steel; Described rolling element adopts the cylindrical roller of steel, or the ceramic cylinder roller that adopts silicon nitride ceramics to make, and promptly rolling element 3 also can adopt silicon nitride ceramic material; Seal ring piece 5 can adopt rubber material, and retainer 4 can adopt engineering plastics (as PA66, PEEK) or metal (as copper, aluminium) to make.
When bearing working, inner ring 1 drives rolling element 3 and the rotation of retainer 4 assemblies, outer ring 2 and two seal ring pieces 5 keep motionless, two seal ring pieces 5 remain non-contact with inner ring 1 or slightly contact in the bearing rotary course, guarantee both to have kept good sealing effect with inner ring 1, it is excessive to be unlikely to friction to occur again, produces superheating phenomenon.
