Abstract
The utility model provides a pure rolling three-row cone-roller type slewing bearing and belongs to slewing bearings. The pure rolling three-row cone-roller type slewing bearing is characterized in that an upper roller path and a lower roller path are both roller paths with frustum-shaped cross sections, wherein the diameters of the outer side ends of the frustum-shaped roller paths are larger than those of the inner side ends of the frustum-shaped roller paths, and the cone angles of the frustum-shaped roller paths can be 0.1 DEG-10.00 DEG; upper cone rollers (upper rolling cones) and frame-shaped upper isolation blocks are uniformly distributed in the frustum-shaped upper roller path along the circumference in sequence; lower cone rollers (lower rolling cones) and frame-shaped lower isolation blocks are uniformly distributed in the frustum-shaped lower roller path along the circumference in sequence; and the cone angles of the upper and the lower cone rollers can be 0.1 DEG-10.00 DEG correspondingly. When the slewing bearing is in use, the linear velocity of the large ends of the upper rollers and the lower cone rollers and that of the small ends are different and are corresponding to the rolling distances, so that the abrasion between the cone rollers and the frustum-shaped roller paths can be reduced effectively, and the service life of the slewing bearing can be prolonged.
Description
Technical field
The utility model belongs to pivoting support, especially relates to a kind of three row's roller type pivoting supports.
Background technique
The roller that traditional roller type pivoting support is selected for use is isodiametric cylindrical body; To be axis place along the radial direction of pivoting support this isodiametric cylindrical body, and in the turning course of pivoting support, the rotating speed of the circumferencial direction of these roller two ends (promptly near an end of gyration center with from the gyration center the other end far away) is identical; And the distance that two ends turn over separately is different; This has just caused wherein one to bring out at present and slide, and this sliding aggravated the wearing and tearing of roller and raceway on the one hand; Cause rotation dumb on the other hand, rub-moment increases.
Summary of the invention
The purpose of the utility model provides a kind of pure rolling three row's tapper roller type pivoting supports, and is not only rational in infrastructure, uses reliably, and reduces the wearing and tearing of roller and raceway effectively, improves the bearing capacity of pivoting support.
The purpose of the utility model realizes like this: a kind of pure rolling three row's tapper roller type pivoting supports; Comprise outer ring, interior Shang Quan, Nei Xiaquan, roller, oil duct and Stamping Steel Ribbon; The inboard of this outer ring has annular boss; Interior Shang Quan leans on down seam delineation position and in each axial hole, installs bolt and be fixedly connected with interior between the circle; The upper surface of outer ring annular boss and interior on offer raceway between the circle, at the lower surface and the interior raceway down of offering between the circle down of outer ring annular boss, enclose down at interior Shang Quan and interior between the internal surface of connecting part and outer ring annular boss of seam and offer middle raceway; Roller and spacing block are installed in the raceway hereinto; At interior Shang Quan with interiorly down offer the upper, middle and lower oil duct respectively on the circle, with the lubricated upper, middle and lower of correspondence raceway, corresponding installation Stamping Steel Ribbon I, Stamping Steel Ribbon II and Stamping Steel Ribbon III between interior Shang Quan, Nei Xiaquan and outer ring; It is characterized in that: raceway is the raceway that cross section is taper type with following raceway on this; And the outboard end diameter of the raceway of this taper type is big and the medial extremity diameter is little; The cone angle of this taper type raceway all can be 0.1o-10.00o; Spacing block on tapered roller on circumference uniform distribution is placed successively in the raceway on this taper type (go up tapper) and the shaped as frame (on each tapered roller correspondence be placed on each shaped as frame in the spacing block); Circumference uniform distribution is placed down spacing block under the tapered roller (following tapper) and shaped as frame (each time tapered roller correspondence be placed under each shaped as frame in the spacing block), all corresponding 0.1o-10.00o that can be of cone angle beta of tapered roller and following tapered roller on this successively in the following raceway of this taper type.
During use, the linear velocity of the big small end of this upper and lower tapered roller is different, and adapts with the distance that is turned over, and has reduced the wearing and tearing of tapered roller (tapper) and circular cone raceway effectively, has prolonged the working life of pivoting support.
Pure rolling that the utility model proposes three row's tapper roller type pivoting supports, rational in infrastructure, use reliably, reduced the wearing and tearing of tapered roller and raceway effectively, prolonged the working life of pivoting support.
Combine accompanying drawing and embodiment that pure rolling three row's tapper roller type pivoting supports that the utility model proposed are described further at present.
