Abstract
The invention discloses an outer tooth three-row-roller type slewing supporting bearing. The outer tooth three-row-roller type slewing supporting bearing comprises inner rings, outer rings and three rows of cylindrical rollers which are arranged between the inner rings and the outer rings, wherein the three rows of cylindrical rollers are arranged in a step shape. The inner rings comprise a second inner ring 11 and a first inner ring 6 which are juxtaposed and connected through a bolt 10. In order to guarantee the sealing performance, upper end faces and lower end faces of the inner rings and the outer ring 1 are respectively sealed through a first sealing ring 2 and a second sealing ring 3. According to the outer tooth three-row-roller type slewing supporting bearing, the three rows of cylindrical rollers are arranged in the ladder shape, and axial force is shared by each roller row while radial force is born, so that the whole rigidity of the bearing is strengthened. By means of the outer tooth three-row-roller type slewing supporting bearing, strength and stiffness of a structure are improved, the weight of the structure is reduced, and the loading capacity of the slewing supporting bearing is improved. A rotary table and a machine body are effectively coordinated and are perfectly combined, and the loading capacity of the rotary table is improved, so that the rotary table is enabled to achieve operating requirements of special products.
Description
Technical field
The present invention relates to field of bearings, more particularly, relate to the turntable special bearing.
Background technique
Bearing is that collection rotates and is transmitted in all over the body, dwindles structure space, alleviates the special-purpose member of weight of equipment.Particularly radar turntable, Armored Recovery Vehicle turntable etc. need highi degree of accuracy, low noise, high impact loads, rotate turret plant stably, and these all need special bearing to realize.
Summary of the invention
The present invention aims to provide a kind of special bearing, and the turntable that is used on the equipment such as radar, Armored Recovery Vehicle uses, and is intended to improve the strength and stiffness of structure, alleviates the weight of structure.Increased the load-carrying ability of this pivoting support.Effectively coordinate turntable and fuselage, it is perfectly combined, and make the maximum effect of radar performance, better strengthened the load-carrying ability of turntable, make it reach the usage requirement of specialities fully.
In order to achieve the above object, the invention provides a kind of external tooth three-row roller formula pivoting support bearing, comprise inner ring, outer ring, and the three-row cylinder roller that arranges both.Wherein, described inner ring comprises that the up and down connects juxtaposed the second inner ring and the first inner ring by bolt; The upper-end surface outer rim radial shape that is positioned at described second inner ring of top circularizes projection; The lower end surface outer rim radial shape that is positioned at described first inner ring of below circularizes projection.Inwardly form annular flange flange in the middle of the internal diameter of described outer ring, inlay the middle part with two annular protrusions in described inner ring up and down.Space between the annular protrusion on described annular flange flange and described the second inner ring has held second row cylindrical roller, the second retainer.Space between the annular protrusion on described annular flange flange and described the first inner ring has held first row cylindrical roller, the second retainer.Space between described annular flange flange inwall and described interior ring outer wall has held three-row cylinder roller; And described three-row cylinder roller is embedded in the circular groove of described the second inner ring and the formation of the first inner ring intersection; Described inner ring, place, upper and lower end face, outer ring are respectively by the first seal ring and the sealing of the second seal ring.In addition, offer profile of tooth on the outer wall of described outer ring.
The present invention selects the outer ring to fix by use condition, and is provided with external toothing, relies on external toothing to rotate.The present invention increases the bearing of turntable working life, and the pivoting support bearing transmission efficiency is high, and reliable operation is simple in structure, compact, makes the performance of radar and Armored Recovery Vehicle more stable, and efficient is higher.In addition, by rationally determining each unit of key stressed member and the shape and size that respectively form the component cross section, be conducive to improve the strength and stiffness of structure, alleviate the weight of structure.Increased the load-carrying ability of this pivoting support.Effectively coordinate turntable and fuselage, it is perfectly combined, and make the maximum effect of radar performance.In addition, three-row cylinder roller of the present invention is the ladder installing to be put, and in the carrying radial force, has shared separately axial force, thereby has strengthened the integral rigidity of bearing.
Description of drawings
Fig. 1 is that 1/4th of external tooth three-row roller formula pivoting support bearing of the present invention cuts open structural representation.
Embodiment
A kind of external tooth three-row roller formula pivoting support bearing, comprise inner ring, outer ring 1 as shown in Figure 1, and the three-row cylinder roller that arranges both.Wherein, described inner ring comprises that the up and down connects juxtaposed the second inner ring 11 and the first inner ring 6 by bolt 10; The upper-end surface outer rim radial shape that is positioned at described second inner ring 11 of top circularizes projection; The lower end surface outer rim radial shape that is positioned at described first inner ring 6 of below circularizes projection, as the back-up ring of cylindrical roller both ends of the surface.
Inwardly form annular flange flange in the middle of 1 internal diameter of described outer ring, inlay the middle part with two annular protrusions in described inner ring up and down.
Space between the annular protrusion on described annular flange flange and described the second inner ring 11 has held second row cylindrical roller 7, the second retainer 8; Space between the annular protrusion on described annular flange flange and described the first inner ring 6 has held first row cylindrical roller 4, the first retainer 5.
Space between described annular flange flange inwall and described interior ring outer wall has held three-row cylinder roller 9; And described three-row cylinder roller 9 is embedded in the circular groove of described the second inner ring 11 and the first inner ring 6 intersections formation.
Described inner ring, 1 place, upper and lower end face, outer ring are respectively by the first seal ring 2 and the second seal ring 3 sealings.Offer profile of tooth on the outer wall of described outer ring.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technological scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
