Abstract
The utility model discloses a three-row roller rotating support, which comprises an upper ring and a lower ring, wherein the upper ring is connected with the lower ring through a bolt to form an outer ring structure; a gear ring is positioned in the outer ring structure; a boss is formed on the side surface of the gear ring; an upper raceway is formed between the upper surface of the boss and the upper ring; an upper row of rollers are arranged in the upper raceway; an lower raceway is formed between the lower surface of the boss and the lower ring; a lower row of rollers are arranged in the lower raceway; a radial raceway is formed between the side surface of the boss and the outer ring structure; radial rollers are arranged in the radial raceway; the inner edge of the upper ring and the upper end of the gear ring are connected with a double-seal ring; and the lower end of the gear ring is connected with a lower sealing strip. All rolling elements of the three rows of rollers bear respective load specifically assigned, and the upper and the lower rows of rollers bear load at 90 degrees, so as to fully achieve the bearing efficiency of all the bearing rollers. Therefore, the three-row roller rotating support has higher axial bearing capacity, radial bearing capacity, and bearing capacity of overturning moment, and meets the requirement for the 360-degree rotating support for engineering machines, particularly for cranes, stockers, ladle turrets and the like.
Description
Technical field
The utility model relates to a kind of roller type pivoting support that is used for engineering machinery.
Background technique
The structure of known roller type pivoting support is to be equipped with row's roller between outer ring and the inner ring.Its defective is: because the mean load of application is higher and the hard work condition, to the requirement of axial force radial force and tilting moment, have potential safety hazard when known single row type pivoting support can't satisfy engineering machinery especially hoist uses, the life-span is short.
Summary of the invention
The defective dangerous in order to overcome existing roller type pivoting support, that the life-span is short, the utility model provide a kind of three row's roller type pivoting supports, and this three rows roller type pivoting support is safe and reliable, and the life-span is long.
The technological scheme that its technical problem that solves the utility model adopts is: this pivoting support comprises Shang Quan and Xia Quan, last circle links to each other with following circle by bolt and forms outer ring structure, gear ring is positioned at outer ring structure, the gear ring side is provided with boss, be provided with raceway between the top and last circle of boss, the row's of being equipped with roller in the last raceway, be provided with down raceway between the following and following circle of boss, be equipped with down row's roller in the following raceway, be provided with radially raceway between the side of boss and the outer ring structure, radially be equipped with radial roller in the raceway, on enclose inner edge and gear ring upper end and be connected with the double density seal, the gear ring lower end is connected with the lower seal band.
The utility model is equipped with three row's rollers, each the rolling element bearing capacity division of labor of three row's rollers is clear and definite, arrange roller carrying 900 up and down, give full play to the carrying usefulness of respectively carrying roller, therefore the bearing capacity that has bigger axial force, radial force and tilting moment, satisfied engineering machinery especially hoist, stocker, ladle turret etc. to the requirement of pivoting support 3600.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. circle on, arrange on 2. roller, 3. the double-sealing band, 4. gear ring, 5. oilhole, 6. radial roller, 7. descend row's roller, 8. time circle, 9. lower seal band.
Embodiment
In Fig. 1, on enclose 1 by the bolt formation outer ring structure that links to each other with following circle 8, gear ring 4 is positioned at outer ring structure.Gear ring 4 sides are provided with boss, are provided with raceway between the top and last circle 1 of boss, the row's of being equipped with roller 2 in the last raceway.Be provided with down raceway between the following and following circle 8 of boss, be equipped with down row's roller 7 in the following raceway.Be provided with radially raceway between the side of boss and the outer ring structure, radially be equipped with radial roller 6 in the raceway.Last circle 1 inner edge and gear ring 4 upper ends are connected with double density seal 3, and gear ring 4 lower ends are connected with lower seal band 9.
Last circle 1 and following circle 8 are ring part, connect the common outer ring structure that forms with bolt, and the while is provided with mounting hole at circumference uniform distribution.In addition, gear ring 4 also is a ring part, coil structures in forming, and circumference uniform distribution is offered vertical mounting hole on gear ring 4.Last circle 1 is placed the row's of going up roller 2, bears maximum thrust load, and play circle 8 is placed row's roller 7 down, carries tilting moments jointly with last row's roller 2, prevents that stressed generation from tumbling, and plays the maintenance effect.Radial roller 6 bearing radial forces.Each the rolling element bearing capacity division of labor of three row's rollers is clear and definite, arrange 90 ° of roller carryings up and down, give full play to the carrying usefulness of respectively carrying roller, therefore the bearing capacity that has bigger axial force, radial force and tilting moment, satisfied engineering machinery especially hoist, stocker, ladle turret etc. to turning round 360 ° requirement.
The window shape spacing block of being furnished with particular design between adjacent two rollers, and this spacing block material selection selflubricating ability material preferably, long service life, the sassafras resistance that rubs is little, economy and durability; During high temperature, configuration metal spacing block satisfies hot environment and uses.
Laterally offer the oilhole that communicates with three row's raceways on 8 ring bodies at last circle 1 and following the circle, at this oilhole periphery lubricating cup is installed respectively, oilhole 5 is divided into three rows to raceway filling lubricant grease, with lubricating of maintenance raceway and roller.
Be positioned at the position on plane on the inner teeth wheel rim and offer annular groove in order to sealing strip is installed at the position of the inner ring surface of outer ring, adopt double sealing structure to prevent because the big not tight drawback of single sealing strip of using of step difference distance, simultaneously offer lower seal band 9 at the outer ring surface that encloses 8 lower inner gear ring down, closure tape construction can prevent that rainwater, dust from entering raceway, increases the service life.
During installation, will go up circle 1 and be inverted, the corresponding row's of going up roller 2 and the spacing block placed finishes until filling in raceway.The mounting teeth wheel rim 4 then, the same in raceway corresponding radial roller 6, row's roller 7 and the spacing block down placed, finish until filling, circle 8 down is installed.To assemble product upset packing at last, and during use pivoting support will be connected with bolt with the main frame bearing, undersetting fuses on the main frame like this, it can be turned round mutually and can bear bigger axial force, radial force and tilting moment.
