Abstract
The utility model discloses a novel dustproof multi-lubrication angular contact ball and roller type slewing bearing. The bearing comprises a shaft washer, a housing washer, rollers and steel balls, wherein a first sealing closing ring and a third sealing closing ring are fixed on the shaft washer through bolts; a second sealing closing ring is fixed on the housing washer through the bolt; a single-lip sealing ring is arranged on the third sealing closing ring; and a double-lip sealing ring is arranged in a groove formed by the shaft washer and the third sealing closing ring. In the novel dustproof multi-lubrication angular contact ball and roller type slewing bearing of the utility model, a sealing device is formed by the sealing closing ring, the single-lip sealing ring and the double-lip sealing ring, so that oxidizing gases and microparticles in air are prevented from entering the bearing to ensure the safety of the operation of the bearing; a multi-lubrication passage is adopted to ensure that the lubrication of key parts of the bearing and the sealing property of the bearing sealing device; a single-row angular contact ball and single-row roller type structure is adopted to ensure that the bearing can simultaneously bear larger axial acting force and axial and radial combined acting force; and the rotation speed of the bearing is also obviously improved.
Description
Technical field
The utility model is applied to mining equipment steering base, belongs to smelting ore deposit technical field, relates in particular to a kind of novel dustproof many lubricated angular contact balls, roller type turntable bearing.
Background technique
In the prior art, because the work under bad environment of mining equipment, in the working procedure, bearing on the mining equipment bears bigger axial and radial force easily, and a large amount of dusts and the airborne particle of many dust infiltrate in the bearing grease easily, cause the bearing strength in the mining equipment equipment bigger, Security reduces, rotating speed weakens greatly, therefore, demand urgently a kind ofly can satisfying mining equipment and in bad working environment, working, can bear bigger axially and radial force, the bearing means of lubricated and good sealing effect.
Summary of the invention
The purpose of this utility model provides a kind of bigger axial force and radial force of bearing, and novel preventing dust lubricated and good sealing effect lubricated angular contact balls, roller type turntable bearings more.
The technological scheme that the utility model is adopted for achieving the above object is: a kind of novel dustproof many lubricated angular contact balls, roller type turntable bearing, comprise blowout patche, seat ring, roller and steel ball, by bolt first Sealing shield ring and the 3rd Sealing shield ring are arranged on the described blowout patche, by bolt second Sealing shield ring is arranged on the described seat ring, single lip seal circle is installed on described the 3rd Sealing shield ring, in the groove that blowout patche and the 3rd Sealing shield ring form double-lip sealing ring is installed.
Described roller is single cylindrical roller.
Described steel ball adopts single angular contact ball structure.
Novel dustproof many lubricated angular contact balls of the present utility model, roller type turntable bearing, Sealing shield ring and single lip double-lip sealing ring are formed seal arrangement, prevent that particulate enters 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
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the novel dustproof many lubricated angular contact balls of the utility model, 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 novel dustproof many lubricated angular contact balls of the utility model, roller type turntable bearing, comprise 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, first Sealing shield ring 4 and the 3rd Sealing shield ring 7 are by being bolted on the blowout patche 1, second Sealing shield ring 6 is by being bolted on the seat ring 2, single lip seal circle 8 is installed on the 3rd Sealing shield ring 7, single lip seal circle 8 bottoms are embedded in the 3rd Sealing shield ring 7, 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, two lips contact with the circular groove upper and lower end face of seat ring 2 respectively, roller 3 and steel ball 4 adopt single cylindrical roller and single angular contact ball structure, 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.
