Abstract
The utility model discloses a stepped positioning four-point contact ball type slewing supporting bearing, which comprises an inner ring (1), an outer ring (4) and a four-point ball type roller (3). The inner ring includes two vertically split annular outer rings, a ball stopper is erected between the two split outer rings, taper pins are penetratingly arranged in the inner ring and the ball stopper along directions parallel to the axis of the bearing at intervals so that the inner ring and the ball stopper are fixed, a countersunk groove is formed by the upper portion of the inner ring and the inner periphery of the ball stopper, correspondingly, an inwards protruded annular flange is formed by the lower portion of the inner ring and the inner periphery of the ball stopper, a mounting hole is axially disposed on the annular flange, a positioning groove is arranged on the inner periphery of the lower end surface of the outer ring, an annular outer boss is arranged on the outer periphery of the lower end surface of the outer ring, a threaded slot is disposed on the boss, an oil injection channel which runs through to the roller is disposed in the threaded slot, the upper portion and the lower portion of the outer wall of the outer ring are cylindrical surfaces, and the middle of the outer wall of the outer ring is a conical surface. The bearing is positioned in a stepped manner via multiple points, the requirement of automatic installation and positioning is met, and rotary positioning, displacement, repeated positioning and repeated displacement can be realized automatically.
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 present invention provides location, species stage four-point contact ball slewing block bearing, it is characterized in that, comprises inner ring, outer ring, and the four-point contact ball formula roller that is provided with between the two; The place of ring interface up and down of said inner ring, outer ring handing-over is provided with O-ring seal.Said inner ring is two annular outer rings of up and down split, sets up ball blocking block between two split outer rings, and said inner ring and said ball blocking block the edge direction of BEARING SHAFT according to one's conscience wear taper pin at interval and fix; Said ball blocking block inner ring radially offers tapped hole.The said inner ring above being positioned at and the internal diameter of ball blocking block form the countersunk head groove, and be corresponding, and the said inner ring below being positioned at and the internal diameter of ball blocking block form the annular flange flange of convex, axial mounting holes on the said annular flange flange.The lower end surface internal diameter of said outer ring is provided with locating slot, and the lower end surface external diameter of said outer ring is provided with the annular outer platform, offers the screw thread slotted eye on the said boss, is provided with the oiling passage that passes to said roller place in the said screw thread slotted eye; The outer wall of said 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 automatic installing and locating through the cascade multipoint positioning; Can realize rotation positioning, displacement and resetting, displacement automatically.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,, help improving the strength and stiffness of structure, alleviate the weight of structure through rationally confirming each unit of key stressed member and the shape and size of respectively forming the component cross section.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.
