Abstract
The utility model discloses an inner-ring and outer-tooth double-row ball slewing bearing which comprises an inner ring (8), outer rings (2), rolling bodies (4), isolation blocks (5) and sealing rings (6), wherein the middle part of the inner ring (8) extends out; an outer tooth (1) is machined on the extending part; the diameter of the tooth root of the outer tooth (1) is greater than the outer diameter of each outer ring (2); the outer rings (2) comprise an upper outer ring and a lower outer ring; the upper outer ring and the lower outer ring are structurally symmetric. The inner-ring and outer-tooth double-row ball slewing bearing can be used in occasions with special requirements on transmission output and mounting positions, namely special occasions in which the mounting positions are on the outer rings and transmission input or output is also performed on the outer rings, for example, the fields of military industries, ships, large-size engineering machinery and the like.
Description
Technical field
The present invention relates to a kind of pivoting support, be specifically related to the double ball pivoting support of a kind of inner ring external tooth.
Background technique
The toothed double ball pivoting support of present inner ring can only be used for fixing outer ring, and on inner ring, internal tooth drives annex work, can not be suitable for the occasion that special mounting requires, as military project, boats and ships, engineering equipment etc.
Summary of the invention
The occasion requiring for being suitable for special mounting, the present invention adopts the outer toothing of " T " font inner ring, and having changed traditional inner ring can only be with the structure of the double ball pivoting support of internal tooth, and having broken through behind fixing outer ring can only be by the mode of internal tooth drive.
The present invention includes inner ring, outer ring, rolling element, spacing block, seal ring.
The intermediate portion of inner ring stretches out, and is processed with external tooth, and the root diameter of its external tooth exceedes the external diameter of outer ring.
Outer ring comprises He Xia outer ring, outer ring.
On inner ring and two outer rings, be all processed with attachment hole.
The beneficial effects of the utility model:
The utility model can be used for transmission output installation position and is equipped with the occasion of particular/special requirement, mounting point in outer ring, transmission inputs or outputs the also special occasions in outer ring, as military project,, the field such as boats and ships, large-scale engineering machinery.
Also external tooth can be made to helical teeth and substitute worm gear use, such as turbine in solar energy sun-seeking device.
Brief description of the drawings
Be illustrated as the plan view (employing fracture the technique of painting) of the double ball pivoting support of a kind of inner ring external tooth of the utility model.
In figure: 1, external tooth; 2, outer ring; 3, outer ring attachment hole; 4, rolling element; 5, isolating frame; 6, seal ring; 7, inner ring attachment hole; 8, inner ring.
Embodiment
