Abstract
The invention discloses a self-positioning outer-tooth four-point contact ball-type slewing bearing. The self-positioning outer-tooth four-point contact ball-type slewing bearing comprises inner rings (6), an outer ring (1) and a four-point contact ball roller (2) arranged between the inner rings (6) and the outer ring (1). The inner rings are two annular inner rings which are vertically separated, a ball blocking block (4) is arranged between the two separated inner rings in an erecting mode, and taper pins (5) are arranged on the inner rings and the ball blocking block at intervals in a penetrating mode along the direction parallel with the axis of the bearing so that the inner rings and the ball blocking block are fixed. An annular sealing ring (3) is arranged on a lower annular connector where the inner rings and the outer ring are connected. A tooth shape is formed on the outer wall of the outer ring, and the upper inner edge and the lower inner edge of the tooth shape are respectively designed to be in a 45-degree chamfer angle with the thickness of 2mm. Connecting threaded holes are formed in the annular circumference in the middle of the inner wall of the ball blocking block at intervals. Besides, the upper end surface and the lower end surface of the outer ring are provided with axial installation holes in a penetrating mode, and the inner edge of the upper end surface of the outer ring is provided with a countersunk groove (7). According to the self-positioning outer-tooth four-point contact ball-type slewing bearing, the countersunk groove is formed in the bearing outer ring, and therefore the demands of automatic installation positioning can be met; and rotating positioning, rotating displacement, repositioning and re-displacement 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 the countersunk head groove is 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 four-point contact ball slewing block bearing, comprise inner ring, outer ring, and 4 contact ball rollers that arrange both; Described inner ring is two annular inner rings of two-piece unit, sets up ball blocking block between two split inner 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.The lower ring interface place of described inner ring, outer ring handing-over arranges O-ring seal; The outer wall of described outer ring offers profile of tooth, and the inner edge up and down of described profile of tooth is arranged to respectively 2 millimeters chamferings of 45 degree; The spaced apart connecting thread hole of being provided with on described ball blocking block inwall intermediate annular circumference.In addition, the upper and lower end face of described outer ring offers axial mounting hole in the perforation mode, and upper-end surface, described outer ring inner edge offers the countersunk head groove.
Bearing satisfies the needs of Auto-mounting location by the countersunk head groove is 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 four-point contact ball slewing block bearing of the present invention partly cut open structural representation.
Embodiment
Self-positioning external tooth four-point contact ball slewing block bearing, comprise inner ring 6, outer ring 1 as shown in Figure 1, and 4 contact ball rollers 2 that arrange both; Described inner ring 6 is two annular inner rings of two-piece unit, sets up ball blocking block 4 between two split inner rings, and it is fixing that described inner ring 6 and described ball blocking block 4 wear taper pin 5 along the direction interval of BEARING SHAFT according to one's conscience; The lower ring interface place of described inner ring 6, outer ring 1 handing-over arranges O-ring seal 3.
The outer wall of described outer ring 1 offers profile of tooth, and the inner edge up and down of described profile of tooth is arranged to respectively 2 millimeters chamferings of 45 degree.The spaced apart connecting thread hole of being provided with on described ball blocking block 4 inwall intermediate annular circumference; In addition, the upper and lower end face of described outer ring 1 offers axial mounting hole in the perforation mode, and upper-end surface, described outer ring inner edge offers countersunk head groove 7.
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.
