Particularly, the joint of the end face of the body of described secondary inner ring and the inner side surface of described flanging had oil groove, and this crosses oil groove entirety ringwise, for carrying more lubricant oil, to reduce resistance.
Further, there is between the inner side end of described a pair secondary inner ring the first gap, for carrying lubricant oil, to reduce resistance.
Further, there is the second gap for carrying lubricant oil between the inner side end of described a pair secondary outer ring, to reduce resistance.
During concrete enforcement, the internal diameter size of the quantity of described roller, the diameter of roller and bridge hoop is suitable for being fitted to each other, between the curve bath being engaged in bridge hoop inner ring to make the activity of described roller and the circular groove of adjacent roller, and the diameter of roller is made to be greater than the spacing of described a pair adjacent circular groove; Coordinating of circular groove on the curve bath of roller and bridge hoop inner ring, roller, limit the moving position of roller, and decrease movable resistance.
As a kind of scheme of global optimization, at same arcuate positions, described a pair secondary inner ring is respectively provided with a roller, this is to roller axle to symmetrical, and the inner end of contiguous each roller is located at by described circular groove; Described roller is between the circular groove of the adjacent roller of same circle distribution; The curve bath being suitable for coordinating with described roller activity of described bridge hoop inner ring comprises a pair that is oppositely arranged with described circular groove.
As the scheme optimized further, the end face of the body of described secondary inner ring is centroclinal inclined-plane, to improve axis, radial load ability further.
During concrete enforcement, described roller is truncated cone, and the tip portion of the roller of this truncated cone is described inner end; Described roller entirety is located on the body of single secondary inner ring.The roller of truncated cone is suitable for axial force to decompose radial direction, and therefore have better axial load ability, roller can not produce displacement; The roller clearance that the bearing of this structure adopts is less, is suitable for adopting a fairly large number of roller, is beneficial to and increases radial load ability.
Further, the tip portion of axially adjacent roller has gap, and to prevent from rubbing between the tip portion of adjacent roller, this gap is suitable for carrying lubricant oil, to increase lubricant oil space simultaneously.
As the scheme optimized further, the outer side edge of described secondary outer ring has the second flanging extended radially inwardly, and the exterior edge face of roller is in the inner side of this second flanging, to prevent roller axle to displacement, and improves radial load ability.
For improving the bulk strength of bearing, the inner side drive fit of described secondary inner ring has inner ring, and described secondary inner ring comprises a pair that is axially symmetrically distributed in described inner ring periphery.
The assembly method of above-mentioned bearing, comprises successively:
Described bridge hoop is located in described outer ring, then described a pair secondary outer ring is symmetricly set between outer ring and bridge hoop;
