Description
Technical Field
The utility model relates to a bearing technical field especially relates to a subdivision formula has double-row circular cone combination bearing of aligning performance.
Background
In gear drive system, because helical gear and gear shaft meshing produce very big axial force, consequently, require the support bearing of gear shaft to bear very big axial force, again because the misalignment of seat hole reaches the flexural deformation of axle, support bearing still will have aligning performance, in prior art, there is a two outer lane aligning tapered roller bearing, this structure bearing has fine aligning performance, the bearing also can bear great axial force simultaneously, but in actual production and the use, the following problem has appeared:
1. the bearing second outer ring is of an integrated structure, in the structural design, a process notch for assembling the first outer ring is required to be processed on the end face of the second outer ring, so that the processing difficulty is increased, the bearing performance of the bearing is reduced due to the process notch, and meanwhile, the installation difficulty of a large-scale bearing is increased due to the integrated structure of the second outer ring;
2. in the long-time use process of the bearing, due to the abrasion of the raceway, the bearing clearance is increased, the precision and the service life of the bearing cannot be guaranteed due to the increased clearance, the bearing clearance cannot be repaired or adjusted again, and the bearing can be only scrapped too early;
3. the bearing lubrication is performed by spraying lubrication at two ends of the bearing close to the large head end of the roller, but because the large gasket of the retainer close to the large head end of the bearing roller has large radial section width, the lubricating oil is prevented from smoothly entering the bearing, and the bearing is not beneficial to fast and fully lubricating;
4. in the aligning working process of the bearing, because the outer diameter surface of the second outer ring of the bearing is matched with the bearing box body, the second outer ring is fixed and does not rotate, the first outer ring rotates along with the aligning of the shaft and the inner ring and is screwed out, the end surface of the first outer ring protrudes out of the end surface of the second outer ring, and the phenomenon of interference and abrasion of the first outer ring and the peripheral matching part of the bearing often occurs.
These problems greatly affect the normal use of the bearing and cause great economic loss to users, so that the invention of a special structure bearing is urgently needed to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide a subdivision formula has double-row circular cone combination bearing of aligning performance.
In order to solve the technical problem, the technical scheme of the utility model is that: the split double-row conical combined bearing with the aligning performance comprises an inner ring, wherein the inner ring comprises two half inner rings, an inner spacer ring is arranged between the two half inner rings, and two rows of conical rollers are arranged on the outer circumferences of the two half inner rings in a surrounding manner through a retainer; the outer sleeves of the two rows of tapered rollers are provided with first outer rings, and the outer sleeves of the first outer rings are provided with second outer rings; the second outer ring comprises two split outer rings, and the connecting bolt penetrates through the end face of the split outer ring on one side to fixedly connect the two split outer rings; the width of the first outer ring is smaller than that of the second outer ring; the conical inner raceway of the first outer ring is in rolling connection with two rows of conical rollers, and the spherical outer raceway of the first outer ring is in rolling connection with the spherical inner raceway of the second outer ring.
Furthermore, the spherical outer raceway of the first outer ring and the spherical inner raceway of the second outer ring have the same self-aligning curvature spherical diameter.
Furthermore, the retainer adopts a steel plate frame type stamping structure.
The utility model has the advantages that:
1. the bearing second outer ring is designed into a split structure, the two split outer rings can be connected into a whole through the connecting bolt, the design can eliminate a process gap for assembling the first outer ring on the end surface of the second outer ring, the processing difficulty is reduced, the adverse factor of the bearing capacity reduction caused by the existence of a process port is eliminated, and meanwhile, the split type two-body structure of the second outer ring can be disassembled and installed in the bearing installation process, so that the installation difficulty of a large-scale bearing is greatly reduced;
2. an inner spacer is added between the end faces of the two half inner rings, and after the bearing is used for a long time, when the bearing clearance is increased, the bearing clearance can be adjusted by exchanging the inner spacer, so that the bearing clearance is ensured to be in a normal working range, the service life of the bearing is prolonged, and the maintenance cost is reduced;
3. the bearing retainer part adopts a steel plate frame type stamping structure, and because the steel plate is thin, the occupied radial cross section space is small, and the bearing is hardly obstructed during jet lubrication, the smoothness of a bearing lubricating oil path is ensured, and the bearing can be quickly and fully lubricated;
4. when the first outer ring of bearing is designed, the whole width is smaller than that of the second outer ring, and the change design of the structure can ensure that the end face of the first outer ring protrudes out of the end face of the second outer ring in the process of aligning work change of the bearing, so that the phenomenon of interference and abrasion between the first outer ring and the peripheral matching part of the bearing is avoided.
The utility model discloses when having the aligning and can bear great axial force performance, still possess the clearance adjustable, the production installation is convenient, bearing capacity maximize, lubricated accessible, structure safe and reliable's comprehensive properties.
