Abstract
A seal arrangement for pivoting support, comprising cross section is circular piston ring, the upper and lower both sides of rolling element groove of the inner ring of pivoting support, each setting at least two piston ring grooves, and cross section is that circular piston ring is loaded in piston ring groove.Inner ring is circumferentially evenly distributed with oil permeable hole, oil permeable hole to be located on the downside of rolling element groove and on the upside of piston ring groove between, oil permeable hole is positioned at below the internal tooth of pivoting support.In the present invention, pivoting support is resistance to appliance, and cross section is circular piston ring is also resistance to appliance, and the cooperation of the two is mated very much.The present invention is not fragile, long service life, favorable sealing property, and gear oil not easily leaks, and the several years is without the need to maintenance.The Cross section Design of piston ring is circular by the present invention, 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 support.
Description
Technical field
The present invention relates to a kind of seal arrangement of pivoting support, particularly relate to a kind of piston ring and substitute the application of rubber seal 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.The pivoting support moment works in rugged environment, existing pivoting support all adopts rubber seal as seal arrangement, rubber seal easily aging, oiling and coming off, thus causes rubber seal to be damaged, cause seal failure, it is very difficult that dismounting changed by seal ring.Pivoting support is resistance to appliance, 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 use lubricating grease, cause the filling of lubricating grease frequent, generally needs filling in tens of hours once, and can only 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, 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, comprising cross section is circular piston ring, the upper and lower both sides of rolling element groove of the inner ring of pivoting support, each setting at least two piston ring grooves, and cross section is that circular piston ring is loaded in piston ring groove.Inner ring is circumferentially evenly distributed with oil permeable hole, oil permeable hole to be located on the downside of rolling element groove and on the upside of piston ring groove between, oil permeable hole is positioned at below the internal tooth of pivoting support.
The seal arrangement of the pivoting support of the present invention has good seal action, and pivoting support can use gear oil.Under the effect of the pressure, gear oil, by inner ring circumferentially equally distributed oil permeable hole, makes cross section be that circular piston ring and rolling element can obtain good lubrication fully.
The seal arrangement of the present invention is applied on pivoting support, the inner ring of pivoting support is fixed on base, good sealing is required between base and turntable, turntable is fixed on outer ring, base is provided with the drain oil of convenient operation, and drain oil is equipped with valve, and the turntable driven 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 resistance to appliance, and cross section is circular piston ring is also resistance to appliance, and the cooperation of the two is mated very much.The present invention is not fragile, long service life, favorable sealing property, and gear oil not easily leaks, and the several years is without the need to maintenance.The Cross section Design of piston ring is circular by the present invention, 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 support.
Accompanying drawing explanation
Fig. 1 is the sectional view after seal arrangement of the present invention and pivoting support assemble;
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, it is circular piston ring 5 that the present embodiment comprises cross section, rolling element groove about 4 both sides of the inner ring 2 of pivoting support, each setting at least two piston ring grooves 6, and cross section is that circular piston ring 5 is loaded in piston ring groove 6.Inner ring 2 is circumferentially evenly distributed with oil permeable hole 3, oil permeable hole 3 to be located on the downside of rolling element groove 4 and on the upside of piston ring groove 6 between, oil permeable hole 3 is positioned at below the internal tooth 1 of pivoting support.
The seal arrangement of the pivoting support of the present invention has good seal action, and pivoting support can use gear oil.Under the effect of the pressure, gear oil, by inner ring 2 circumferentially equally distributed oil permeable hole 3, makes cross section be that circular piston ring 5 and the rolling element be placed in rolling element groove 4 can obtain good lubrication fully.
The seal arrangement of the present invention is applied on pivoting support, the inner ring 2 of pivoting support is fixed on base, good sealing is required between base and turntable, turntable is fixed on outer ring 7, base is provided with the drain oil of convenient operation, and drain oil is equipped with valve, and the turntable driven 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.
