Abstract

The utility model provides a three-row ball type pivoting support, which belongs to a pivoting support and is characterized in that an upper roller path, a middle roller path and a lower roller path which are provided with circular cross sections are evenly symmetrically arranged between the circumference of an inner circle of an outer ring and the circumference of an outer circle of an inner ring form top to bottom. An upper plug hole, a middle plug hole and a lower plug hole which are provided with the same diameter are respectively arranged at the right portion of the outer ring in the radial direction and slidingly respectively matched with installed cylindrical plugs. A through hole with the same cone is respectively arranged on the upper plug, the middle plug and the lower plug from top to bottom at the right portion of the outer ring, and taper pins with the same taper are installed in the through holes with the same cone so as to fix the upper plug, the middle plug and the lower plug on the outer ring. The outer ring and the inner ring of the pivoting support are supported to each other through three rows of steel balls and rotate relatively, thereby greatly improving bearing capacity of the pivoting support and achieving the purpose that the requirement of a host machine for high performance and high load can be satisfied under the condition that the size of the pivoting support is relatively fixed.

Description

Three row ball type slewing bearings
Technical field
The utility model belongs to pivoting support, especially relates to a kind of ball-type slewing bearing.
Background technique
Along with the application of pivoting support is more and more wider, the performance of the main frame of use pivoting support is more and more higher, load is also increasing, but when main frame maximizes, the impossible unconfined amplification in space of pivoting support is installed, it is the size of pivoting support, especially radial dimension is restricted, traditional single-row ball type slewing bearing will satisfy bigger load, will select bigger raceway diameter and rolling element for use, thereby radial dimension is strengthened, and the size of pivoting support also strengthens, and can not satisfy the demand of growing high loading high-performance mechanical.
Summary of the invention
The purpose of this utility model provides a kind of three row ball type slewing bearings, this pivoting support is under the less relatively situation of radial dimension, possess advantages of high bearing capacity and tilting moment, further satisfy main frame and maximize and the high performance requirement of high loading, enlarge the market share of pivoting support.
The purpose of this utility model is achieved like this: a kind of three row ball type slewing bearings, comprise the outer ring, inner ring, steel ball (rolling element), spacing block, taper pin and obstruction, it is characterized in that: between the outer peripheral surface of the inner peripheral surface of outer ring and inner ring, uniform from top to bottom and offer cross section symmetrically and be circular last raceway, middle raceway and following raceway, raceway on this, in raceway and following raceway all on the outer peripheral surface of the inner peripheral surface of outer ring and inner ring, be symmetrical arranged, on this, in, in the following raceway respectively circumference uniform distribution ground steel ball and spacing block are installed successively, each steel ball and spacing block are installed in raceway from plugging hole, the right part of outer ring corresponding on, in, the position of the radial centre lines of following raceway is radially offered respectively with last, in, on the same diameter that following raceway correspondence communicates, in, following plugging hole also makes on this, in, the center line of following plugging hole (axially) is positioned on the same vertical surface, last, in, cylindrical obstruction is slidingly installed respectively in the following plugging hole, on the right part of outer ring and this, in, offer same cone-shaped hole from top to bottom in the following obstruction, equipped taper pin in this cone-shaped hole with tapering, to go up, in, following obstruction is fixed on the outer ring, the left part of outer ring corresponding on, in, following raceway is offered oilhole and spinning oil nozzle radially respectively, to make progress, in, the lubricant grease of annotating in the following raceway, in addition, the connecting part of upper and lower end face is installed Stamping Steel Ribbon respectively raceway is sealed between outer ring and inner ring, like this, the outer ring of pivoting support and inner ring also relatively rotate by the mutual support of three row's steel balls (rolling element), improve the bearing capacity of pivoting support greatly, reached pivoting support satisfies the requirement of main frame high-performance high loading under the relatively-stationary prerequisite of size purpose.
Three row ball type slewing bearings that the utility model proposed, rational in infrastructure, safe and reliable, possess advantages of high bearing capacity and tilting moment, further satisfy main frame and maximized and the high performance requirement of high loading, further enlarged the market share of pivoting support.
Now in conjunction with the accompanying drawings and embodiments three row ball type slewing bearings that the utility model proposed are described further.
Description of drawings
Fig. 1 is the main cross-sectional schematic of three row ball type slewing bearings that propose of the utility model.
Among Fig. 1: 1, oil nozzle 2, outer ring 3, steel ball 4, last raceway 5, inner ring 6, Stamping Steel Ribbon 7, taper pin 8, obstruction 9, middle raceway 10, following raceway.
Embodiment
