Abstract
The invention discloses a novel combined cage of a cylindrical roller bearing. The cage mainly comprises a steel support column (2) and a steel cage retaining ring (3), wherein, an axial oil groove is formed at the steel support column (2), the steel support column (2) evenly separates rollers (4) distributed on roller paths of an outer ring (1) and an inner ring (5) of the cylindrical roller bearing, and the two ends of the steel support column (2) are matched with holes on the steel cage retaining ring (3) and riveted and pressed firmly. The novel combined cage of the cylindrical roller bearing has the advantages that the structure is simple, the fabricating cost is reduced, and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to bearing manufacturing technology field, relate in particular to novel combined cage of cylindrical roller bearing.
Background technique
All the time, each bearing MANUFACTURER copper retainers that adopt on roller bearing more.Along with country economizes on resources and deeply implementing of environmental protection environment and constantly bringing forth new ideas of bearing technology, each bearing MANUFACTURER is had higher requirement, require its manufacture cost to reduce, prolong the working life of bearing.
Summary of the invention
The purpose of this invention is to provide a kind of novel combined cage of cylindrical roller bearing, it is simple in structure, has reduced manufacture cost, has prolonged the working life of bearing.
In order to achieve the above object, technological scheme of the present invention is as follows:
Novel combined cage of cylindrical roller bearing, mainly form by steel pillar and steel retainer back-up ring, the steel pillar has axial oil groove, the roller that the steel pillar will be distributed on the raceway that the Internal and external cycle of roller bearing forms is evenly separated, match with the hole on the steel retainer back-up ring in the two ends of steel pillar, and riveting is firm.
The invention has the beneficial effects as follows: this retainer is similar to car system copper cage performance, but has reduced a large amount of manufacture costs; Compare with pressing cage, performance index such as its mechanical strength, mechanical property, vibration noise, running accuracy all have clear improvement; It is about 25% that the load rating capacity of bearing improves, and bearing life improves 1～1.2 times.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, outer ring, 2, the steel pillar, 3, steel retainer back-up ring, 4, roller, 5, inner ring.
Embodiment
Below in conjunction with accompanying drawing the present invention is done description in further detail:
As shown in Figure 1, the present invention mainly is made up of steel pillar 2 and steel retainer back-up ring 3, and steel pillar 2 has axial oil groove, and roller 4 is distributed on the raceway of outer ring 1 and inner ring 5 formation, and is evenly separated by several steel pillars 2; Match with the hole on the steel retainer back-up ring 3 in the two ends of steel pillar 2, and riveting is firm, thereby form combined cage of cylindrical roller bearing.
The present invention adopts ferrous metal to substitute the copper retainer, explores a kind of novel combined cage that is applicable to roller bearing, two ends steel back-up ring assembled scheme.The retainer structure of two ends steel retainer back-up ring 3 and steel pillar 2, similar to car system copper cage performance, but can reduce a large amount of manufacture costs; Compare with pressing cage, performance index such as its mechanical strength, mechanical property, vibration noise, running accuracy all have clear improvement.It is about 25% that the load rating capacity of bearing improves, and bearing life improves 1～1.2 times.
Cage pin 2 usefulness Fine Steel Casting iron cold-drawn moulding of the present invention, two back-up ring 3 cold-rolling steel-plate punch moulding, the cage pin 2 of moulding and back-up ring 3 finished products use high-precision mold that the part stack mounting is guaranteed assembly precision fully.
Cage pin 2 takes into full account the requirement of roller bearing handling characteristics at design aspect, and the structural design uniqueness adopts mould cold-drawn moulding, reduces the friction factor between roller 4 and the retainer, improves its wear-resisting property; Simultaneously, cage pin 2 has axial oil groove, guarantees that roller 4 contacts enough lubricant greases with raceway, has improved the greasy property of retainer, the working life of having improved bearing widely.No matter combined cage of cylindrical roller bearing of the present invention is better than the copper retainer fully on mechanical property and usability, through certain industrial and mining enterprise is on probation at home, especially use on petroleum machinery, respond well, has obtained user's extensive welcome.
Retainer back-up ring 3 adopts punch forming process, and component interchanging precision height has been simplified the Operating Complexity of assembling.
