Abstract
The invention discloses a novel dustproof multi-lubrication angular contact ball and roller type slewing bearing which comprises a shaft washer, a seat ring, a roller and a steel ball, wherein a first sealing retaining ring and a third sealing retaining ring are fixedly arranged on the shaft washer through bolts, a second sealing retaining ring is fixedly arranged on the seat ring through the bolt, a single-lip sealing ring is mounted on the third sealing retaining ring, and a double-lip sealing ring is mounted in a slot formed by the shaft washer and the third sealing retaining ring. The novel dustproof multi-lubrication angular contact ball and roller type slewing bearing uses the sealing retaining rings and the single-lip and the double-lip sealing rings to constitute a sealing device, thereby being capable of preventing oxidizing gas and particles in the air from entering into the bearing and ensuring the safety of the operation of the bearing; the adoption of multiple lubrication channels can ensure the lubrication of key parts of the bearing and the sealing property of the sealing device of the bearing; and the adoption of single-row angular contact balls and single-row cylindrical structures and further ensure that the bearing can simultaneously bear greater axial action force and the axial and radial combined action force; and the rotational speed of the bearing is also significantly improved.
Description
Technical field
The present invention is applied to mining equipment steering base, belongs to smelting ore deposit technical field, relates in particular to a kind of dustproof many lubricated angular contact balls, roller type turntable bearing.
Background technique
In the existing technology, because the work under bad environment of mining equipment, in the working procedure; Bearing on the mining equipment bear easily bigger axially and radial force, and a large amount of dusts and the airborne particle of many dust infiltrate in the bearing grease easily, causes the bearing strength in the mining apparatus bigger; Security reduces; Rotating speed weakens greatly, therefore, demands urgently a kind ofly can satisfying mining equipment and in bad working environment, working; Can bear bigger axial and radial force, lubricate bearing means with good sealing effect.
Summary of the invention
The purpose of this invention is to provide a kind of bigger axial force and radial force of bearing, lubricated and preventing dust of good sealing effect lubricated angular contact balls, roller type turntable bearings more.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of dustproof many lubricated angular contact balls, roller type turntable bearing; Comprise blowout patche, seat ring, roller and steel ball; Through bolt first Sealing shield ring and the 3rd Sealing shield ring are arranged on the said blowout patche; Through bolt second Sealing shield ring is arranged on the said seat ring, single lip seal circle is installed on said the 3rd Sealing shield ring, in the groove that blowout patche and the 3rd Sealing shield ring form double-lip sealing ring is installed.
Said roller is single cylindrical roller.
Said steel ball adopts single angular contact ball structure.
Dustproof many lubricated angular contact balls of the present invention, roller type turntable bearing; Sealing shield ring and single lip double-lip sealing ring are formed seal arrangement; Prevent that particulate gets in the bearing in oxidizing gas and the air, effectively dust is intercepted outside bearing race, guaranteed the Security of bearing operation; Adopt many lubrication channels, guarantee the sealability of the lubricated and associated sealing arrangement for bearings of bearing key position; Adopt single angular contact ball and single column type structure, guarantee that bearing can bear bigger axial and axial and united active force simultaneously; The rotating speed of bearing also is significantly improved.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the dustproof many lubricated angular contact balls of the present invention, roller type turntable bearing structural representation.
Among the figure: 1, blowout patche; 2, seat ring; 3, roller; 4, steel ball; 5, first Sealing shield ring; 6, second Sealing shield ring; 7, the 3rd Sealing shield ring; 8, single lip seal circle; 9, double-lip sealing ring.
Embodiment
As shown in Figure 1; The much more dustproof lubricated angular contact balls of the present invention, roller type turntable bearings comprise that blowout patche 1, seat ring 2, roller 3, steel ball 4, first Sealing shield ring 5, second Sealing shield ring 6, the 3rd Sealing shield ring 7, single lip seal circle 8, double-lip sealing ring 9, the first Sealing shield rings 4 and the 3rd Sealing shield ring 7 are through being bolted on the blowout patche 1; Second Sealing shield ring 6 is through being bolted on the seat ring 2; Single lip seal circle 8 is installed on the 3rd Sealing shield ring 7, and single lip seal circle 8 bottoms are embedded in the 3rd Sealing shield ring 7, and single lip seal circle lip contacts with seat ring 2 upper-end surfaces; Double-lip sealing ring 9 is installed in the groove of blowout patche 1 and 7 formation of the 3rd Sealing shield ring; The bottom of double-lip sealing ring 9 is embedded in the groove of blowout patche 2 and 7 formation of the 3rd Sealing shield ring, and two lips contact with the circular groove upper and lower end face of seat ring 2 respectively, and roller 3 adopts single cylindrical roller and single angular contact ball structures with steel ball 4; Bearing not only can bear larger axis to power; Also can bear larger axis to united active force, radially adopt ball stressed, the rotating speed of bearing also is significantly improved.
