Abstract
The utility model provides a bearing sealing device. A bearing is arranged in a bearing pedestal. The sealing device comprises a sealing cover and a pressing mechanism, wherein the sealing cover is pressed on the end surface of the bearing pedestal through the pressing mechanism, an annular sealing groove is formed in a contact surface between the sealing cover and a shaft, and a sealing ring is arranged in the annular sealing groove. As a plurality of sealing measures, such as combination between the sealing ring and the pressing mechanism are adopted, the bearing sealing device is reliable to seal and convenient to mount and maintain.
Description
Technical field
The utility model relates to a kind of seal arrangement of bearing, is applicable to the occasion that is subject to external environment factor affecting sealing effect.
Background technique
Bearing is one of important foundation component of all kinds of machinery, and it is widely used in industrial every field.The precision of bearing, performance, life-span and reliability be to precision, performance, life-span and the reliability decisive role of main frame, is a vital part in the basic component of machinery.In use the sealing of bearing directly influences the performance of bearing, and then influences the operation of main frame or system.Just seem very necessary so design a kind of simple and effective associated sealing arrangement for bearings.And the most employing of the seal arrangement of existing bearing is oil sealing sealing, packing seal, mechanical seal etc., when bearing is in the environment that is subject to seawater corrosion or air oxidation, more than single seal arrangement possibly can't satisfy the sealing demand of bearing, this just needs multiple seal approach in conjunction with the seal request that just can reach bearing, cost height so not only, lost time, nor be beneficial to the maintenance in later stage.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of associated sealing arrangement for bearings, and sealing is reliable, and installation and maintenance are convenient.
The utility model is achieved in that a kind of associated sealing arrangement for bearings, bearing is located in the bearing support, it is characterized in that: described seal arrangement comprises sealing cover and hold-down mechanism, described sealing cover is pressed on the end face of described bearing support by this hold-down mechanism, and described sealing cover is provided with annular seal groove with the surface of contact of axle, is provided with seal ring in this annular seal groove.
Further, described hold-down mechanism comprises that double-screw bolt, spring seat and compression spring, described spring seat are connected on the described sealing cover by double-screw bolt, and described compression spring housing is located on the double-screw bolt between spring seat and the sealing cover.
Further, the junction surface between described sealing cover and the bearing support is provided with a plurality of oil storage tanks, is filled with lubricating grease in the oil storage tank.
Further, the cross section of described oil storage tank is rectangle; Described seal ring is the O RunddichtringO; Described sealing cover is the teflon seal lid.
Advantage of the present utility model is: associated sealing arrangement for bearings of the present utility model has adopted multiple-sealed measures such as seal ring and hold-down mechanism combine, strengthened the sealability of bearing greatly, make bearing in use avoid seawater corrosion, the influence of external factors such as air oxidation, the utility model is installed simply simultaneously, and effect is obvious.Working life and the working efficiency of bearing have been guaranteed.
Description of drawings
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the utility model associated sealing arrangement for bearings one preferred embodiment.
Embodiment
See also shown in Figure 1, associated sealing arrangement for bearings of the present utility model, bearing (not shown) is located in the bearing support 1 and is set on the axle 2, seal arrangement 3 comprises sealing cover 31 and hold-down mechanism 32, described sealing cover 31 is pressed on the end face of described bearing support 1 by this hold-down mechanism 32, and described sealing cover 31 is provided with annular seal groove 311 with the surface of contact of axle 2, is provided with seal ring 33 in this annular seal groove 311; Described seal ring 33 can be O RunddichtringO or other seal ring.
Described hold-down mechanism 32 comprises that double-screw bolt 321, spring seat 322 and compression spring 323, described spring seat 322 are connected on the described sealing cover 31 by double-screw bolt 321, and described compression spring 323 is set on the double-screw bolt 321 between spring seat 322 and the sealing cover 31.Wherein, for stressed even, hold-down mechanism 32 can arrange a plurality of.
Junction surface between described sealing cover 31 and the bearing support 1 is provided with a plurality of oil storage tanks 34, and oil storage tank 34 can be located on the sealing cover 31, also can be located on the bearing support 1; The cross section of described oil storage tank 34 can be rectangle; Oil storage tank is filled with lubricating grease for 34 li.
Described sealing cover 31 is the teflon seal lid, adopt teflon to make sealing cover, have do not absorb water, non-conductive, high temperature resistant, advantages of high strength, can effectively reduce the frictional force between seal arrangement 3 and the bearing support 1 and strengthen the sealing of whole sealing device 3.
The characteristics of the utility model associated sealing arrangement for bearings:
When 1, assembling, earlier bearing is placed in the bearing support 1, and be set on the axle 2, again seal ring 33 is placed in the annular seal groove 311 of sealing cover 31, then sealing cover 31 also is set in axle 2 and exists, and be close to bearing support 1; Be connected on the sealing cover 31 after at last hold-down mechanism 32 being assembled, and make compression spring 323 be in compressive state.
2, after assembling was finished, sealing cover 31 closely contacted with bearing support 1, and sealing cover 31 can effectively reduce the frictional force between seal arrangement 3 and the bearing support 1 and strengthen the sealing of whole sealing device.When bearing in use occurs wearing and tearing, can rely on the tension force of compression spring 323 again, can with sealing cover 31 extruding downwards and with bearing seamless combination again.So not only can protect bearing not to be subjected to the influence of extraneous factors such as seawater corrosion and air oxidation, can also prevent that the lubricating grease of 34 li of oil storage tanks from flowing out the operation that influences bearing and axle 2.
As mentioned above, associated sealing arrangement for bearings of the present utility model has adopted multiple-sealed measures such as seal ring and hold-down mechanism combine, strengthened the sealability of bearing greatly, make bearing in use avoid seawater corrosion, the influence of external factors such as air oxidation, the utility model is installed simply simultaneously, and effect is obvious.Working life and the working efficiency of bearing have been guaranteed.
Though more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
