Abstract
A double-row ball type slewing bearing provided with an inner ring with an outer tooth comprises the inner ring (8), an outer ring (2), a rolling body (4), an isolating block (5) and a sealing ring (6), wherein the middle part of the inner ring (8) extends out, the outer tooth (1) is processed in the extending part, and the diameter of the root of the outer tooth (1) is larger than the outer diameter of the outer ring (2); and the outer ring (2) comprises an upper outer ring and a lower outer ring which are symmetric. The double-row ball type slewing bearing can be used in occasions with special requirements for transmission output and mounting positions, namely, special occasions that the mounting position and the transmission input or output position are located on the outer ring, for example, the fields of the military industry, a ship, large 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
Below in conjunction with the drawings and specific embodiments, the double ball pivoting support of a kind of inner ring external tooth of the utility model is described in further detail.
The double ball pivoting support of a kind of inner ring external tooth, comprises inner ring 8, outer ring 2, rolling element 4, spacing block 5, seal ring 6.
The intermediate portion of inner ring 8 stretches out, and is processed with external tooth 1 at extension, and the root diameter of external tooth 1 exceedes the external diameter of outer ring 2.
Outer ring 2 comprises He Xia outer ring, outer ring, upper outer ring and lower outer ring structure symmetry.
On outer ring 2, there is outer ring attachment hole 3.
On inner ring 8, have inner ring attachment hole 7, depending on concrete condition, inner ring attachment hole 7 also can be designed to through hole.
Claims (2)
1. the double ball pivoting support of inner ring external tooth, comprise inner ring (8), outer ring (2), rolling element (4), spacing block (5), seal ring (6), it is characterized in that: the intermediate portion of inner ring (8) stretches out, be processed with external tooth (1) at extension, the root diameter of its external tooth (1) exceedes the external diameter of outer ring (2).
