Abstract
The invention discloses an outer tooth cross roller type slewing supporting bearing. The outer tooth cross roller type slewing supporting bearing comprises inner rings (6), outer rings (1) and a cross roller (2) which is arranged between the inner rings (6) and the outer rings (1). The inner rings (6) are two annular inner rings which are split in an up-down mode, a ball blocking block (4) is erected between the two split outer rings, and the inner rings and the ball blocking block (4) are fixed by taper pins (5) which are arranged along the axes of a flat core bearing at intervals. Annular sealing rings (3) are arranged on upper annular connectors and lower annular connectors of the inner rings and the outer rings. Tooth forms are formed on outer walls of the outer rings, and up and down inner edges of the tooth forms are respectively arranged to be rounding chamfers with an angle of 45 degrees and the height of 2 millimeters. Connecting threaded holes are formed in the annular circumference in the center of an inner wall of the ball blocking block (4) at intervals. The outer rings are selected and fixed according to the service condition, a tooth ring is arranged, and the tooth ring is driven by an outer tooth ring to revolve. By means of the outer tooth cross roller type slewing supporting bearing, the service life of the bearing of a rotary table is prolonged and transmission efficiency of the slewing supporting bearing is increased. The outer tooth cross roller type slewing supporting bearing is simple and compact in structure, and the performance of radar and an armoured emergency service vehicle is stabilized and efficiency is improved.
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 external tooth crossed roller-type pivoting support bearing, comprise inner ring, outer ring, and the crossed roller that arranges 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 ring interface up and down 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.
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 external tooth crossed roller-type pivoting support bearing of the present invention partly cut open structural representation.
Embodiment
The external tooth crossed roller-type pivoting support bearing, comprise inner ring 6, outer ring 1 as shown in Figure 1, and the crossed roller 2 that arranges 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 ring interface up and down 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.
Take into full account the installation position of this pivoting support during design, Environmental Conditions, working state, working speed and the factor such as accept.The axial basic static capacity (BSC) rating capacity that this pivoting support of process designing and calculating can bear, basic static capacity (BSC) rating capacity radially, the equivalent thrust load provides this pivoting support suffered thrust load according to the user, and the size of radial load tilting moment calculates the safety coefficient of this pivoting support.
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.
