Abstract
The invention provides a split type spherical outer ring roller bearing. The inside of a bearing outer ring is provided with two bearing inner rings, and two roller racks in which rollers are arranged are arranged between the bearing outer ring and the two bearing inner rings; the outer surface of the bearing outer ring is spherical; and the roller racks are disconnected with the bearing outer ring and the bearing inner rings. For the split type spherical outer ring roller bearing adopting the structure, when the bearing axially swings, the bearing wholly swings, so that the rollers are evenly stressed, the bearing capacity is greatly improved, the bearing can be loaded with enough pre-tightening force when assembled, the bearing capacity applied on the bearing is even, and the service life of the bearing is prolonged. The bearing has the advantages of big bearing capacity, long service life and the like, and can be widely applied to rotary mechanical parts.
Description
Technical field
The invention belongs to the technical field of bearings that is used for rotating part, be specifically related to the bearings with rolling contact that is mainly used in radial load with two row or multiple row roller.
Background technique
Bearing is a kind of component that sliding friction are converted into rolling friction and play certain supporting effect in solid of rotation, is widely used between the fitting surface of various rotating machinerys.
At present, the application of bearing is very extensive, plays crucial effects in rotatablely moving.But the bearing structure of Xiao Shouing is that outer ring and inner ring are integrated type in the market, works as bearing like this and is applied on the machinery of axial runout, and the inner roller of bearing can partly de-orbit, and causes the bearing capacity of bearing to descend.For keeping bearing to rotate flexibly, need to keep certain interval between outer ring, inner ring and the roller simultaneously.When the load-carrying load acts on the bearing, make shaft strength downward, all bearing upper half part is transferred in the gap.The bearing capacity of bearing lower half portion increases, the bearing capacity of upper half part reduces, the power that bearing bore is inhomogeneous, irregular bearing capacity affacts on the bearing, quickened the wearing and tearing of bearing, reduced the working life of bearing, in case bearing is damaged or is stuck, bearings mounted machinery will be damaged, and will cause having an accident when serious.
Summary of the invention
Technical problem to be solved by this invention is to overcome the shortcoming of above-mentioned bearing, provides that a kind of reasonable in design, simple in structure, bearing capacity is big, the split type spherical outer ring roller bearing of long service life.
Solving the problems of the technologies described above the technological scheme that is adopted is: be provided with two bearing inner races in the bearing outer ring, two roller stands of roller are housed in being provided with between bearing outer ring and two bearing inner races, the outer surface of bearing outer ring is a sphere, and roller stand does not link to each other with bearing inner race with bearing outer ring.
The spherical radius R of bearing outer ring of the present invention is 10～10000mm.
The outer surface of bearing outer ring of the present invention is a sphere shape, internal surface is a vertebra shape structure, the outer surface of bearing inner race is taper, form centrum between bearing outer ring internal surface and the bearing inner race outer surface, it is split-type structural that the roller stand of roller and bearing outer ring and bearing inner race are installed, be arranged in the centrum between bearing outer ring internal surface and the bearing inner race outer surface, bearing is when axial runout, bearing is done as a whole swing, roller is stressed evenly, bearing capacity improves greatly, bearing can add enough pretightening forces in installation process, the suffered bearing capacity of bearing is even, the working life of having improved bearing.The present invention has advantages such as bearing capacity is big, long service life, can extensively promote the use of on rotary mechanical parts.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Embodiment
The present invention is described in more detail below in conjunction with drawings and Examples, but the invention is not restricted to these embodiments.
In Fig. 1, the split type spherical outer ring roller bearing of present embodiment is made of bearing outer ring 1, roller 2, bearing inner race 3, roller stand 4 connections.
Two bearing inner races 3 are installed in bearing outer ring 1, and the outer surface of bearing outer ring 1 is a sphere, and spherical radius R is 5000mm, the internal surface of bearing outer ring 1 is a conical surface, and cone angle is β, and the internal surface of bearing inner race 3 is the cylndrical surface, the outer surface of bearing inner race 3 is a conical surface, and cone angle is α.Constitute the ring-type round platform space of two mutual UNICOMs between the outer surface of the internal surface of bearing outer ring 1 and bearing inner race 3.In the ring-type round platform space between the outer surface of the internal surface of bearing outer ring 1 and bearing inner race 3 two roller stands 4 are installed, roller 2 is installed in the roller stand 4, roller 2 be shaped as Rotary-table, the concrete geometrical shape of roller can be determined according to conventional design in the size employing mechanical design handbook of bearing capacity, the concrete quantity of roller 2 is determined according to the external diameter of bearing inner race 3, the external diameter of bearing inner race 3 is big, the quantity of the roller of installing 2 is many, the external diameter of bearing inner race 3 is little, and the quantity of the roller 2 of installation is few.The concrete data of the concrete data of the outer surface conical surface cone angle of bearing inner race 3, the internal surface conical surface cone angle beta of bearing outer ring 1 are determined according to conventional design in the geometrical shape employing mechanical design handbook of roller.The bearing of this structure, when axial runout, bearing is done as a whole swing, and roller is stressed evenly, and bearing capacity improves greatly, and bearing can add enough pretightening forces in installation process, the suffered bearing capacity of bearing is even, the working life of having improved bearing.
The outer surface of present embodiment bearing outer ring 1 is a sphere, spherical radius R is 10mm, roller 2 be shaped as Rotary-table, the concrete geometrical shape of roller can adopt in the mechanical design handbook conventional design to determine that the concrete quantity of roller 2 is determined according to the external diameter of bearing inner race 3 according to the size of bearing capacity.The concrete data of the concrete data of the outer surface conical surface cone angle of bearing inner race 3, the internal surface conical surface cone angle beta of bearing outer ring 1 are determined according to conventional design in the geometrical shape employing mechanical design handbook of roller.The geometrical shape of other component and the connecting relation of component are identical with embodiment 1.
The outer surface of present embodiment bearing outer ring 1 is a sphere, spherical radius R is 10000mm, roller 2 be shaped as Rotary-table, the concrete geometrical shape of roller can determine that the concrete quantity of roller 2 is determined according to the external diameter of bearing inner race 3 according to conventional design in the size employing mechanical design handbook of bearing capacity.The concrete data of the concrete data of the outer surface conical surface cone angle of bearing inner race 3, the internal surface conical surface cone angle beta of bearing outer ring 1 are determined according to conventional design in the geometrical shape employing mechanical design handbook of roller.The geometrical shape of other component and the connecting relation of component are identical with embodiment 1.
Also can design the split type spherical outer ring roller bearing of another concrete structure according to above-mentioned principle, but all within protection scope of the present invention.
