Abstract
The utility model discloses a self-positioning outer-teeth four-point contact ball type slewing bearing. The self-positioning outer-teeth four-point contact ball type slewing bearing comprises an inner ring (6), an outer ring (1), and a four-point contact ball roller (2) which is arranged between the inner ring and the outer ring, wherein the inner ring comprises upper and lower annular inner rings which are split; a ball-blocking block (4) is arranged between the two split inner rings; the inner rings and the ball-blocking block are fixed along the direction in parallel with the axis of the bearing through taper pins (5) which are arranged between the inner rings and the ball-blocking block at intervals; an annular sealing ring (3) is arranged at a lower annular joint of the inner ring and the outer ring; tooth profiles are formed on the outer wall of the outer ring, and upper and lower inner edges of each tooth profile are set as chamfers of 45 degrees and 2 millimeters; connection threaded holes are formed at the annular circumference in the middle of the inner wall of the ball-blocking block at intervals; an axial installation hole penetrates through upper and lower end faces of the outer ring; and a countersunk groove (7) is formed at the inner edge of the upper end face of the outer ring. The self-positioning outer-teeth four-point contact ball type slewing bearing has the advantages that: by forming the countersunk groove on the outer ring of the bearing, requirements for automatic installation positioning are met; and rotation positioning, rotation displacement, repeated positioning and repeated displacement can be automatically realized.
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.Bearing particularly of the present invention satisfies the needs of automatic installing and locating through the countersunk head groove is set on bearing outer ring; Can realize rotation positioning, displacement and resetting, displacement automatically.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 present invention provides a kind of self-align external tooth four-point contact ball slewing block bearing, comprises inner ring, outer ring, and 4 contact ball rollers that are provided with between the two; Said inner ring is two annular inner rings of up and down split, sets up ball blocking block between two split inner rings, and said inner ring wears taper pin at interval with the direction of the parallel BEARING SHAFT in said ball blocking block edge and fixes.The following ring interface place of said inner ring, outer ring handing-over is provided with O-ring seal; The outer wall of said outer ring offers profile of tooth, and the inner edge up and down of said profile of tooth is arranged to 2 millimeters chamferings of 45 degree respectively; The spaced apart connection screw thread hole that is provided with on the said ball blocking block inwall intermediate annular circumference.In addition, the upper and lower end face of said outer ring offers axial mounting hole with the perforation mode, and upper-end surface, said outer ring inner edge offers the countersunk head groove.
Bearing satisfies the needs of automatic installing and locating through the countersunk head groove is set on bearing outer ring; Can realize rotation positioning, displacement and resetting, displacement automatically.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,, 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.
Description of drawings
Fig. 1 be the self-align external tooth four-point contact ball slewing of the present invention block bearing partly cut open structural representation.
Embodiment
Self-align external tooth four-point contact ball slewing block bearing as shown in Figure 1 comprises inner ring 6, outer ring 1, and 4 contact ball rollers 2 that are provided with between the two; Said inner ring 6 is two annular inner rings of up and down split, sets up ball blocking block 4 between two split inner rings, and it is fixing that said inner ring 6 and said ball blocking block 4 wear taper pin 5 at interval along the direction of BEARING SHAFT according to one's conscience; The following ring interface place of said inner ring 6, outer ring 1 handing-over is provided with O-ring seal 3.
The outer wall of said outer ring 1 offers profile of tooth, and the inner edge up and down of said profile of tooth is arranged to 2 millimeters chamferings of 45 degree respectively.The spaced apart connection screw thread hole that is provided with on the said ball blocking block 4 inwall intermediate annular circumference; In addition, the upper and lower end face of said outer ring 1 offers axial mounting hole with the perforation mode, and upper-end surface, said outer ring inner edge offers countersunk head groove 7.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
