Abstract
The invention discloses a double-row cylindrical and tapered roller combination bearing having an outer ring gear. The combination bearing comprises the outer ring gear, tapered roller bearing inner components, middle spacing rings and cylindrical roller bearing inner components. The outer ring gear is an integrated outer ring gear having an outer gear; a double-row cylindrical roller bearing inner component consisting of the two cylindrical roller bearing inner components is arranged on an inner rolling way in the middle of the outer ring gear; one single-row tapered roller bearing inner component is arranged at each of the two sides of the double-row cylindrical roller bearing inner component; the single-row tapered roller bearing inner components at the two sides are arranged on inner rolling ways at the two sides of the outer ring gear; and the middle spacing rings for adjusting the bearing play are arranged between the double-row cylindrical roller bearing inner component and the tapered roller bearing inner components on the two sides. The double-row cylindrical and tapered roller combination bearing has the advantages of simple and compact structure, convenience for disassembly, small occupied space, high bearing capacity and long service life, and is suitable for working conditions of bearing heavy loads and impact loads.
Description
Technical field
The present invention relates to bearing mnanufacture technical field, particularly relate to a kind of biserial cylinder, tapered roller combination bearing of outer astragal gear.
Background technique
Along with planetary transmission is used widely and fast development in the transport facilitys such as land, navigation, aviation, the design difficulty of epicyclic gearbox is increased gradually.To the space of epicyclic gearbox, life-span, complicated load, velocity ratio, operated steadily higher requirement.And patent of the present invention pushes away newly to go out planet gear internal structure on original planetary gear construction basis.Be set as the structural type of circular cone, cylindrical roller combination bearing at planet gear internal, its object is the operating mode such as load, high loading improving this planetary life-span, operate steadily, reduce space, be suitable for complexity.
Summary of the invention
The technical problem to be solved in the present invention, be to provide a kind of biserial cylinder, tapered roller combination bearing of outer astragal gear, this bearing outer ring is external gear, and the mode adopting gear and bearing to combine can directly as planetary pinion, compact structure, take up room and significantly reduce, greatly shorten construction period cost low, bearing load carrying capacity is large, long service life, be applicable to bear heavy load and impact load, avoid the too large premature failure problem of planetary pinion local pressure.
The technological scheme adopted is
The biserial cylinder of outer astragal gear, a tapered roller combination bearing, comprise outer ring gear, tapered roller bearing inner assembly, middle spacer ring, roller bearing inner assembly.Described outer ring gear is the integral type outer race gear of a band external gear, the double-row conical bearing inner assembly be made up of two roller bearing inner assemblies to be arranged in the middle of outer ring gear on raceway, a single-row tapered roller bearing inner assembly is respectively arranged with in the both sides of Biserial cylindrical roller bearing inner assembly, the single-row tapered roller bearing inner assembly of both sides is separately positioned on the interior raceway of gear both sides, outer ring, forms in an outer ring gear and establishes four row cylinders, tapered roller combination bearing.
The middle spacer ring regulating bearing clearance is provided with in the middle of above-mentioned Biserial cylindrical roller bearing inner assembly and both sides tapered roller bearing inner assembly.
The external gear of above-mentioned outer ring gear is spur gear, helical gear or double helical spurgear.
The present invention adopts overall assembly performance good, simple and compact for structure, for convenience detach, and the design of integrated form, effectively saves space, its bearing capacity in limited space is greatly improved, extends the life-span; Owing to there being the use of two single-row tapered roller bearings in inner assembly, make bearing load direction of the present invention multidirectionalization, not only can bear single radial direction, axial force, making a concerted effort of two kinds of directions can also be born, even can bear making a concerted effort of more direction, according to this feature, the gear-type of outer ring can be spur gear, helical gear, the extension of double helical spurgear range of choice, can the axial displacement in restrictive axes or a shell direction according to the feature of tapered roller bearing, therefore the stability of planet wheel obtains optimization.Have roller bearing in inner assembly, the radial bearing capacity of planet wheel is obtained and strengthens targetedly, be applicable to bear heavy load and impact load, friction factor is little.
