Abstract
The utility model discloses a novel combined retainer of cylindrical roller bearing, which mainly consists of a steel brace (2) and a steel retainer closing ring (3), wherein an axial oil groove is opened on the steel strut (2), and the steel strut (2) is used to evenly separate rollers (4) arranged on the rolling paths of an outer ring (1) and an inner ring (2) of a cylindrical roller bearing, and the two ends of the steel strut (2) are matched with holes on the steel retainer closing ring (3), and are riveted firmly. The novel combined retainer has the beneficial effects that the structure is simple, the production cost is reduced, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to bearing manufacturing technology field, relates in particular to a kind of 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.
The model utility content
The purpose of this utility model provides a kind of novel combined cage of cylindrical roller bearing, and it is simple in structure, has reduced manufacture cost, has prolonged the working life of bearing.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of 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 beneficial effects of the utility model are: 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 the structural representation of the utility model combined cage of cylindrical roller bearing.
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 utility model is done description in further detail:
As shown in Figure 1, combined cage of cylindrical roller bearing of the present utility model mainly is made up of steel pillar 2 and steel retainer back-up ring 3, and steel pillar 2 has axial oil groove, 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 utility model 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.
Retainer back-up ring 3 adopts punch forming process, and component interchanging precision height has been simplified the Operating Complexity of assembling.
Claims (1)
