Abstract
The invention discloses an internal tooth cross roller type slewing bearing. The internal tooth cross roller type slewing bearing comprises an inner ring (6), outer rings (1) and a cross roller (5) which is arranged between the inner ring and the outer rings. The outer rings are two up-and-down separate annular outer rings, a blocking ball (3) is erected between the two separate outer rings, and the outer rings and the blocking ball fixedly penetrate a tapered pin (2) along the axis direction of a normal bearing in an interval mode. Annular sealing rings (4) are arranged at an upper annular connector and a lower annular connector, and the upper annular connector and the lower annular connector are connected with the inner ring and the outer rings. A tooth form is arranged on an inner wall of the inner ring, and an upper inner edge and a lower inner edge of the tooth form are respectively set as chamfers of 45 degrees and 2 millimeters. A thread hole is formed in the upper end surface of the inner ring. The inner ring is chosen to fix according to the using condition, and the internal tooth cross roller type slewing bearing is provided with a tooth ring and depends on an inner tooth ring to rotate. By the adoption of the internal tooth cross roller type slewing bearing, the service life of a bearing of a turntable is prolonged, the transmission efficiency of the slewing bearing is high, working is reliable, and the structure is simple and compact, so that radar and an armored recovery vehicle are more stable in performance and higher in efficiency.
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 a kind of internal-tooth-crossed roller type pivoting support bearing, comprise inner ring, outer ring, and the crossed roller that arranges both; Described outer ring is two annular outer rings of two-piece unit, sets up ball blocking block between two split outer rings, and described outer ring and described ball blocking block wear taper pin along the direction interval of BEARING SHAFT according to one's conscience and fix.The ring interface up and down place of described inner ring, outer ring handing-over arranges O-ring seal; The inwall of described inner 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 upper-end surface of described inner ring offers tapped hole.
The present invention selects inner ring to fix by use condition, and is provided with gear ring, relies on ring gear 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 internal-tooth-crossed roller type pivoting support bearing of the present invention partly cut open structural representation.
Embodiment
As shown in Figure 1, a kind of internal-tooth-crossed roller type pivoting support bearing comprises inner ring 6, outer ring 1, and the crossed roller 5 that arranges both.Described outer ring 1 is two annular outer rings of two-piece unit, sets up ball blocking block 3 between two split outer rings, and it is fixing that described outer ring 1 and described ball blocking block 3 wear taper pin 2 along the direction interval of BEARING SHAFT according to one's conscience.Wherein, the ring interface up and down place of described inner ring 6, outer ring 1 handing-over arranges O-ring seal 4; The inwall of described inner ring 6 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 upper-end surface of described inner ring 6 offers tapped hole.
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.
