Abstract
The invention discloses a step positioning four-point contact ball type slewing block bearing. The step positioning four-point contact ball type slewing block bearing comprises inner rings (1), an outer ring (4), and a four-point contact ball type roller (3). The inner rings are two annular outer rings which are separated up and down, a ball blocking block is arranged between the two separated outer rings, the inner rings and the ball blocking block are provided with taper pins for fixing in a spaced and penetrated mode along the direction of a core-parallel bearing axis. The inner ring located on the upper position and the inner diameter of the ball blocking block form a countersunk groove, correspondingly, the inner ring located on the lower position and the inner diameter of the ball blocking block form an annular flange which protrudes inwards, and mounting holes are axially formed in the flange. A positioning groove is formed in the inner diameter of the lower end face of the outer ring, an annular outer boss is arranged on the outer diameter of the lower end face of the outer ring, a thread groove hole is formed in the boss, an oil injection channel which passes to the roller position is arranged in the thread groove hole, the upper part and the lower part of the outer wall of the outer ring are respectively cylindrical surfaces, and the middle of the outer wall of the outer ring is a taper surface. Through step type multipoint positioning, the step positioning four-point contact ball type slewing block bearing is capable of meeting the requirement of automatic mounting and positioning, automatically achieving rotary positioning, deflection, and repeated positioning and deflection.
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 location, a species stage four-point contact ball slewing block bearing, it is characterized in that, comprise inner ring, outer ring, and the four-point contact ball formula roller that arranges both; The ring interface up and down place of described inner ring, outer ring handing-over arranges O-ring seal.Described inner ring is two annular outer rings of two-piece unit, sets up ball blocking block between two split outer rings, and described inner ring and described ball blocking block wear taper pin along the direction interval of BEARING SHAFT according to one's conscience and fix; Described ball blocking block inner ring radially offers tapped hole.Be positioned at the described inner ring of top and the internal diameter of ball blocking block and form the countersunk head groove, corresponding, the described inner ring below being positioned at and the internal diameter of ball blocking block form the annular flange flange of convex, axially offer mounting hole on described annular flange flange.The lower end surface internal diameter of described outer ring arranges locating slot, and the lower end surface external diameter of described outer ring arranges the annular outer platform, offers the screw thread slotted eye on described boss, is provided with the oiling passage that passes to described roller place in described screw thread slotted eye; The outer wall of described outer ring two-part up and down is respectively the cylndrical surface, and the centre is up-small and down-big conical surface.
Bearing satisfies the needs of Auto-mounting location by the cascade multipoint positioning; Can automatically realize rotating location, displacement and resetting, displacement.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 internal-tooth-crossed roller type pivoting support bearing of the present invention partly cut open structural representation.
Embodiment
Ladder location four-point contact ball slewing block bearing, comprise inner ring 1, outer ring 4 as shown in Figure 1, and the ring interface up and down place of the described inner ring 1 of four-point contact ball formula roller 3. that arranges both, outer ring 4 handing-over arranges O-ring seal 2.Described inner ring 1 is two annular outer rings of two-piece unit, sets up ball blocking block 5 between two split outer rings, and it is fixing that described inner ring 1 and described ball blocking block 5 wear taper pin 6 along the direction interval of BEARING SHAFT according to one's conscience; Described ball blocking block 5 inner rings radially offer tapped hole.Be positioned at the described inner ring of top and the internal diameter of ball blocking block 5 and form countersunk head groove 8, corresponding, the described inner ring below being positioned at and the internal diameter of ball blocking block 5 form the annular flange flange 9 of convex, axially offer mounting hole on described annular flange flange 9;
The lower end surface internal diameter of described outer ring 4 arranges locating slot 7, and the lower end surface external diameter of described outer ring 4 arranges annular outer platform 10, offers the screw thread slotted eye on described boss 10, is provided with the oiling passage that passes to described roller 3 places in described screw thread slotted eye.The outer wall of described outer ring 4 two-part up and down is respectively the cylndrical surface, and the centre is up-small and down-big conical surface.
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.
