Abstract
The invention discloses a self-positioning external-tooth crossed roller type slewing bearing. The self-positioning external-tooth crossed roller type slewing bearing comprises inner rings, an outer ring and crossed rollers. A separation block is arranged outside each roller. The inner rings are two annular inner rings which are vertically split and close to each other, threaded holes are formed in the first inner ring above and the second inner ring below in a matched mode, and the first inner ring and the second inner ring are connected through a connecting bolt. An oil filler hole is formed in the position of the inner diameter of the contact surface of the first inner ring and the second inner ring, and the oil filler hole is communicated to the positions where the rollers are located. An upper annular connector and a lower annular connector of connection of each inner ring and the outer ring are respectively provided with an annular sealing ring. Mounting through holes at intervals are formed in the end face of the outer ring in parallel with the direction of a bearing shaft. The outer wall of the outer ring is provided with a tooth profile. Besides, a countersunk groove is formed in the inner edge of the upper end surface of the outer ring, and the outer edge of the lower end surface of the outer ring is shaped like a boss. According to the self-positioning external-tooth crossed roller type slewing bearing, the outer ring of the bearing is provided with the countersunk groove or a step platform, and therefore the demands of automatic installation and positioning are met; and rotary positioning and shifting and repeated positioning and shifting can be automatically achieved.
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.Particularly bearing of the present invention by countersunk head groove or ladder platform are set, satisfies the needs of Auto-mounting location on bearing outer ring; Can automatically realize rotating location, displacement and resetting, displacement.The present invention has also 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 self-positioning external tooth crossed roller-type pivoting support bearing, comprise inner ring, outer ring, and the crossed roller that arranges both; Described roller arranged outside has spacing block.Described inner ring is two-piece unit and two annular inner rings being close together, coordinates on the first inner ring of top and the second inner ring of below to offer tapped hole, and is connected by connecting bolt.And the inner radius of first inner ring and the second inner ring surface of contact offers oil hole, and described oil hole is communicated to described roller present position.The ring interface up and down place of described inner ring, outer ring handing-over arranges O-ring seal.The parallel bearing axis direction in described outer ring is the spaced apart installation through hole that is provided with on end face; The outer wall of described outer ring offers profile of tooth.In addition, upper-end surface, described outer ring inner edge offers the countersunk head groove, and lower end surface, described outer ring outer rim is the boss-shaped setting.
Bearing satisfies the needs of Auto-mounting location by countersunk head groove and boss are set on bearing outer ring; Can automatically realize rotating location, displacement and resetting, displacement.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.
Description of drawings
Fig. 1 be self-positioning external tooth crossed roller-type pivoting support bearing of the present invention partly cut open structural representation.
Embodiment
Self-positioning external tooth crossed roller-type pivoting support bearing as shown in Figure 1, the self-positioning external tooth crossed roller-type pivoting support bearing is characterized in that, comprises inner ring, outer ring 1, and the crossed roller 5 that arranges both; Described roller 5 arranged outside have spacing block 6.Described inner ring is two-piece unit and two annular inner rings being close together, coordinates on the first inner ring 2 of top and the second inner ring 7 of below to offer tapped hole, and is connected by connecting bolt 4; And the inner radius of first inner ring 2 and the second inner ring 7 surface of contact offers oil hole, and described oil hole is communicated to described roller 5 present positions.The ring interface up and down place of described inner ring, outer ring 1 handing-over arranges O-ring seal 3; The parallel bearing axis direction in described outer ring 1 is the spaced apart installation through hole that is provided with on end face; The outer wall of described outer ring 1 offers profile of tooth. and in addition, described outer ring 1 upper-end surface inner edge offers countersunk head groove 8, and described outer ring 1 lower end surface outer rim is boss 9 shape settings.
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.
