Summary of the invention
The purpose of this utility model provides a kind of decussation roller and ball combined type pivoting support, 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 decussation roller and ball combined type pivoting support, comprise the outer ring, inner ring, rolling element, spacing block, taper pin and obstruction, it is characterized in that: the compartment of terrain is offered raceway and following raceway respectively between the outer peripheral surface of the inner peripheral surface of outer ring and inner ring, the cross section that should go up raceway is the square that is provided with about four right angles are presented down, and right angle, the left and right sides and right angle side are symmetrical arranged on the outer peripheral surface of the inner peripheral surface of outer ring and inner ring respectively, raceway becomes roller path on this, the spacing block that cross section is foursquare roller and roller is installed in the raceway on this in uniform way successively, the cross section of this time raceway is rounded and be symmetrical arranged on the outer peripheral surface of the inner peripheral surface of outer ring and inner ring, become ball receway, the spacing block of steel ball and steel ball is installed on circumference uniform distribution ground successively in this following raceway, above-mentioned roller, steel ball and spacing block are loaded into from plugging hole, the right part of outer ring corresponding on, the position of the radial centre lines of following raceway is radially offered respectively with last, on the same diameter that following raceway correspondence communicates, following plugging hole also makes on this, the center line of following plugging hole (axially) is positioned on the same vertical surface, last, cylindrical obstruction is slidingly installed respectively in the following plugging hole, on the right part of outer ring and this, offer cone-shaped hole from top to bottom in the following obstruction, equipped taper pin in this cone-shaped hole with tapering, to go up, following obstruction is fixed on the outer ring, the left part of outer ring corresponding on, following raceway is offered oilhole and spinning oil nozzle radially respectively, to make progress, 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 and the inner ring of pivoting support pass through roller, steel ball (rolling element) support mutually also relatively rotates, last raceway is the roller type raceway, roller is set as rolling element, the bus of adjacent two rollers respectively with outer ring and corresponding contact of roller surface on the inner ring, the submission fork contact, 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.
Decussation roller that the utility model proposed and ball combined type pivoting support, rational in infrastructure, safe and reliable, under the less relatively situation of radial dimension, possess advantages of high bearing capacity and tilting moment, further satisfy main frame and maximized and the high performance requirement of high loading, enlarged the market share of pivoting support.
Now in conjunction with the accompanying drawings and embodiments decussation roller and the ball combined type pivoting support that the utility model proposed is described further.
