Description
Technical field
The invention belongs to technical field of bearings, especially relate to a kind of double-lip seal formula four point touching ball slewing bearing.
Background technique
Four point touching ball slewing bearing is a kind of in the turntable bearing, and its structure is generally shown in Figure 1, is comprised of outer ring 1, inner ring 4, steel ball 2, spacing block 8, upper seal ring 3, lower seal 7 etc.Four point touching ball slewing bearing can bear larger thrust load, radial load and tilting moment simultaneously, is widely used in the various machinery of the industries such as engineering machinery, harbour machinery, Hoisting Machinery, wind-powered electricity generation, iron and steel.
As shown in Figure 1, what conventional four point touching ball slewing bearing adopted is single lipped joint touch sealing, and seal ring is that banded oil resistant rubber is made, wherein a side has a lip, fill in ringwise in the seal groove of inside and outside circle, lip rides on outer ring or the inner ring end face, and the head and the tail docking is bonded.This seal ring can play preferably dust-proof effect, but the lubricating grease that bearing inside often occurs is from seal ring especially jointing leakage phenomenon, thereby the intermittent oiling of having to carries out maintaining.In case in time do not refuel, might cause lubricating grease to be revealed fully, thereby cause dry friction between raceway and the steel ball, so that bearing early failue.In some workplace, need bearing to have better sealability, not only need to prevent the intrusion of the impurity such as extraneous dust, sandy soil and water, also to stop the lubricating grease of bearing inside toward outward leakage.In order to make bearing have better sealability, need to innovate sealing configuration and the performance of bearing.
Summary of the invention
The objective of the invention is to propose a kind of double-lip seal formula four point touching ball slewing bearing, make it not only have well dustproof, waterproof, anti-aging function, can also prevent the leakage of internal lubrication fat, make bearing in its life cycle, need not again to refuel, accomplish non-maintaining, has good sealing effect, compact structure, installation, maintenance, characteristics easy to use.
The present invention adopts following technological scheme for finishing above-mentioned purpose:
A kind of double-lip seal formula four point touching ball slewing bearing, described four point touching ball slewing bearing includes inner ring, outer ring and steel ball; Be provided with seal ring and lower seal; Described upper seal ring, lower seal are the loop configuration of double-lip seal; Two lips that seal that all have to the inside on the body of described upper seal ring, lower seal or stretch out laterally are lip I, lip II; The body of described upper seal ring, lower seal is positioned at the seal groove of outer ring or inner ring, and described lip I rides on the end face of inner ring or outer ring, plays the axial seal effect; Described lip II rides on the aperture surface of the outer diametric plane of inner ring or outer ring, plays the radial seal effect.
When the outer ring upper, inner ring is in lower time, two lips on the described upper seal ring body are that lip I, lip II are stretched out to the inside; The body of described upper seal ring is positioned at the seal groove of outer ring, and described lip I rides on the end face of inner ring, plays the axial seal effect; Described lip II rides on the outer diametric plane of inner ring, plays the radial seal effect; Two lips on the described lower seal body are that lip I, lip II are stretched out laterally; The body of described lower seal is positioned at the seal groove of inner ring, and described lip I rides on the end face of outer ring, plays the axial seal effect; Described lip II rides on the aperture surface of outer ring, plays the radial seal effect.
Descending when the outer ring, inner ring is when upper, and two lips on the described upper seal ring body are that lip I, lip II are stretched out laterally; The body of described upper seal ring is positioned at the seal groove of inner ring, and described lip I rides on the end face of outer ring, plays the axial seal effect; Described lip II rides on the aperture surface of outer ring, plays the radial seal effect; Two lips on the described lower seal body are that lip I, lip II are stretched out to the inside; The body of described lower seal is positioned at the seal groove of outer ring, and described lip I rides on the end face of inner ring, plays the axial seal effect; Described lip II rides on the outer diametric plane of inner ring, plays the radial seal effect.
A kind of double-lip seal formula four point touching ball slewing bearing, the wrapping angle of bearing is 35 °, adopts completely to fill steel ball structure.
A kind of double-lip seal formula four point touching ball slewing bearing that the present invention proposes adopts the sealing of lips formula, make the lip I of seal ring, lower seal and lip II respectively with aperture surface or the applying of outer diametric plane of end face, inner ring or the outer ring of the corresponding inner ring of institute or outer ring; Play simultaneously the effect of axial and radial seal; While is for the concrete applying working condition of this bearing, requirement has higher radially bearing capacity, the novel wrapping angle with bearing of the present invention changes 35 ° into by 45 ° of routine, the cancellation spacing block, increased the steel ball number, radially dynamic load rating and the basic static capacity (BSC) rating ability of bearing are improved greatly, simultaneously can also bear thrust load and tilting moment, in sum, the present invention not only has well dustproof, waterproof, the anti-aging function, can also prevent the leakage of internal lubrication fat, make bearing in its life cycle, need not again to refuel, accomplish non-maintainingly, have good sealing effect, compact structure is installed, safeguard, characteristics easy to use.
