Abstract
A kind of double outer ring floating bearings, including outer ring and inner ring, the outer ring includes upper outer ring and lower outer ring, and the upper outer ring is connected with lower outer ring by connecting bolt, and the outside middle portion of the inner ring is outwardly to form in two annular inner races with taper roller surface under roller surface and annular inner race；The medial surface of the upper outer ring is provided with the taper type roller surface parallel with roller surface on inner ring, and main thrust raceway space is formed between two roller surfaces, upper roller is set in main thrust raceway space, upper roller is arranged in holder；The medial surface of the lower outer ring is provided with the taper type roller surface parallel with roller surface under inner ring, and propulsive thrust raceway space is formed between two roller surfaces, sets lower roller in propulsive thrust raceway space, lower roller is arranged in lower retainer.The utility model adds the integrated carrying ability of pivoting support and bearing capacity of toppling, and the integrated carrying ability of pivoting support is improved 50%~70%.
Description
Technical field
Mechanical equipment technical field is the utility model is related to, more particularly, to a kind of double outer ring floating bearings.
Background technology
The existing pivoting support bearing capacity that topples does not reach customer requirement, in same angle, due to linear velocity not
Together, easily there is roller change tiltedly to take the least important seat at a square table, increase friction, cause heating, burn can be produced when serious；And existing pivoting support roller
Collocation form, integrated carrying ability is weak, and space-consuming is big, and flexibility of revolution is poor, so as to influence the service life of pivoting support.
The content of the invention
In order to overcome the shortcomings of in background technology, being toppled the utility model discloses one kind, bearing load is big, flexible rotation
Steadily and service life length double outer ring floating bearings.
In order to realize the goal of the invention, the utility model adopts the following technical scheme that：A kind of double outer ring floating bearings, bag
Outer ring and inner ring are included, the outer ring includes upper outer ring and lower outer ring, and the upper outer ring is connected with lower outer ring by connecting bolt, institute
The outside middle portion for stating inner ring outwardly forms in two annular inner races with taper raceway under roller surface and annular inner race
Face；The medial surface of the upper outer ring is provided with the taper type roller surface parallel with roller surface on inner ring, between two roller surfaces
Main thrust raceway space is formed, upper roller is set in main thrust raceway space, upper roller is arranged in holder；It is described
The medial surface of lower outer ring is provided with the taper type roller surface parallel with roller surface under inner ring, and counter push away is formed between two roller surfaces
Power raceway space, lower roller is set in propulsive thrust raceway space, and lower roller is arranged in lower retainer.
For further improved technology scheme, the raceway angles in main thrust raceway space described in the utility model are more than or equal to
The raceway angles in propulsive thrust raceway space.
For further improved technology scheme, the raceway angles in main thrust raceway space described in the utility model are less than counter push away
The raceway angles in power raceway space.
For further improved technology scheme, the lower section of the medial surface of upper outer ring described in the utility model is interior with lower outer ring
Vertical line section is provided with above side.
For further improved technology scheme, upper roller roller length described in the utility model is less than main thrust raceway space
Race length.
For further improved technology scheme, the roller length of lower roller described in the utility model is less than propulsive thrust raceway sky
Between race length.
By adopting the above-described technical solution, the utility model has the advantages that：It is described in the utility model double outer
Floating bearing is enclosed, two row's raceways, the design of two row's raceway angulation degree type are provided between inner ring and outer ring, main thrust raceway pushes away with counter
Power raceway is respectively equipped with roller, adds the integrated carrying ability of pivoting support and bearing capacity of toppling.
Two rollers are angled to be used, and rolling element moves along central axial when this pivoting support rotates, avoid roller compared with
When long, in the case where bearing axial load and tipping load, roller surface discontinuity, easily there is roller change and tiltedly beat
Horizontal stroke, increase friction, causes heating, burn can be produced when serious；
For this structure in the case where carrying is certain, the space to be taken is small, saves material, and precision is high, and rotation is steady,
End face run-out is small.Double-row-roller angle type raceway, the integrated carrying ability of pivoting support and bearing capacity of toppling are added, is made back
The integrated carrying ability for turning supporting improves 50%~70%.
