Abstract
The invention provides a seal device for a slewing bearing. The seal device comprises piston rings with annular sections, wherein at least two piston ring grooves are formed in each of the upper and lower sides of a rolling element groove of an inner ring of the slewing bearing, and the piston rings with annular sections are arranged in the piston ring grooves; oil penetration holes are uniformly distributed in the circumference of the inner ring, are formed between the lower side of the rolling element groove and the upper sides of the piston ring grooves, and are positioned below inner teeth of the slewing bearing. According to the invention, the slewing bearing is a durable part, and the piston rings with annular sections are durable parts, so that the slewing bearing and the piston rings are matched with each other excellently. The seal device cannot be damaged easily and is long in service life and excellent in seal performance, gear oil is unlikely to leak and the seal device does not need maintenance in several years; polishing scratches between the piston rings and an outer ring can be smooth due to the round sections of the piston rings, and thus the detachment is convenient. The seal device is applicable to sealing of slewing bearings with various models.
Description
Technical field
The present invention relates to a kind of seal arrangement of pivoting support, relate in particular to the application of a kind of piston ring instead of rubber seal ring in pivoting support seal arrangement.
Background technique
At present, pivoting support comprises inner ring, outer ring and rolling element, and rolling element is located between inner ring and outer ring.Pivoting support works in rugged environment constantly, existing pivoting support all adopts rubber seal as seal arrangement, and rubber seal is aging, oiling and coming off easily, thereby causes rubber seal to be damaged, cause seal failure, it is very difficult that seal ring is changed dismounting.Pivoting support is durable, and rubber seal is easily damaged parts, and the cooperation of the two is very unmatched.Because rubber seal rings for seal performance is bad, so existing pivoting support can only be used lubricating grease, cause the filling of lubricating grease frequent, within general tens of hours, needs are annotated once, and can only be by manually refueling, troublesome poeration.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the above-mentioned defect that prior art exists, and provides a kind of good seal performance, the seal arrangement of the pivoting support that probability of damage is low.
The technical solution adopted for the present invention to solve the technical problems is:
A seal arrangement for pivoting support, comprises that cross section is circular piston ring, the upper and lower both sides of rolling element groove of the inner ring of pivoting support, and each arranges at least two piston ring grooves, and cross section is that circular piston ring is loaded in piston ring groove.On inner ring circumference, be evenly distributed with oil permeable hole, oil permeable hole is located between rolling element groove downside and piston ring groove upside, and oil permeable hole is positioned at the internal tooth below of pivoting support.
The seal arrangement of the present invention's pivoting support has good seal action, and pivoting support can be used gear oil.Under the effect of pressure, gear oil is by equally distributed oil permeable hole on inner ring circumference, and making cross section is that circular piston ring and rolling element can obtain good lubricated fully.
The present invention's seal arrangement is applied on pivoting support, the inner ring of pivoting support is fixed on base, between base and turntable, require to have good sealing, turntable is fixed on outer ring, base is provided with the drain oil of convenient operation, and valve is housed on drain oil, and the turntable driving by electronic/oil hydraulic motor is provided with tank filler sleeve, turntable is provided with oil scale, is convenient to check oil mass.The use of gear oil, also can to internal tooth and coordinate with internal tooth electronic/hydraulic motor gear plays good lubrication.
In the present invention, pivoting support is durable, and cross section is that circular piston ring is also durable, and the cooperation of the two is mated very much.The present invention is not fragile, long service life, and favorable sealing property, gear oil is difficult for leaking, and the several years is without maintenance.The present invention is circular by the Cross section Design of piston ring, makes the polishing scratch between piston ring and outer ring round and smooth, easy accessibility.The present invention is applicable to the sealing of various model pivoting supports.
Accompanying drawing explanation
Fig. 1 is the sectional view after seal arrangement of the present invention and pivoting support assembling;
Fig. 2 is the plan view of the piston ring of seal arrangement of the present invention;
Fig. 3 is the A-A sectional view of the piston ring of seal arrangement of the present invention shown in Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to Fig. 1, Fig. 2 and Fig. 3, the present embodiment comprises that cross section is circular piston ring 5, the rolling element groove of the inner ring 2 of pivoting support both sides Shang Xia 4, and each arranges at least two piston ring grooves 6, and cross section is that circular piston ring 5 is loaded in piston ring groove 6.On inner ring 2 circumference, be evenly distributed with oil permeable hole 3, oil permeable hole 3 is located between rolling element groove 4 downsides and piston ring groove 6 upsides, and oil permeable hole 3 is positioned at internal tooth 1 below of pivoting support.
The seal arrangement of the present invention's pivoting support has good seal action, and pivoting support can be used gear oil.Under the effect of pressure, gear oil is by equally distributed oil permeable hole 3 on inner ring 2 circumference, and making cross section is that circular piston ring 5 can obtain good lubricated fully with the rolling element being placed in rolling element groove 4.
The present invention's seal arrangement is applied on pivoting support, the inner ring 2 of pivoting support is fixed on base, between base and turntable, require to have good sealing, turntable is fixed on outer ring 7, base is provided with the drain oil of convenient operation, and valve is housed on drain oil, and the turntable driving by electronic/oil hydraulic motor is provided with tank filler sleeve, turntable is provided with oil scale, is convenient to check oil mass.The use of gear oil, also can to internal tooth and coordinate with internal tooth electronic/hydraulic motor gear plays good lubrication.
