Abstract
The utility model relates to a bearing sealing device which comprises a main shaft, a bearing, a bearing seat, a bearing end cover and a seal ring, wherein the bearing is arranged outside the main shaft; the bearing seat is arranged outside the bearing; the bearing end cover is mounted at the outer end of the bearing seat; the seal ring is arranged between the bearing and the bearing end cover; an annular groove is formed in the seal ring and is filled with gas. The bearing sealing device provided by the utility model has the beneficial effects that after the device is used for a long time, although a clearance is generated between the seal ring and the main shaft due to friction, as the annular groove is formed in the seal ring, and gas is filled in the annular groove, when the main shaft rotates, heat is generated due to the friction between the seal ring and the main shaft, and then the gas filled in the annular groove expands due to heating, and further the seal ring can expand, and the clearance between the seal ring and the main shaft can be eliminated, the sealing property is improved, the environmental pollution is avoided and also the unnecessary waste is avoided.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of associated sealing arrangement for bearings.
Background technique
Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.The purpose of bearing seal is to prevent the leaking outside of lubricant oil in the bearing portion, and it is inner to prevent that the harmful objects such as outside dust, moisture, foreign matter from invading bearings, so that bearing can be under desired cond, and safety and lasting running.General associated sealing arrangement for bearings as shown in Figure 1, comprises main shaft 1, bearing 2, bearing support 3, bearing (ball) cover 4 and seal ring 5, the main shaft 1 outer bearing 2 that is provided with, be provided with bearing support 3 outside the described bearing 2, bearing support 3 outer ends are equipped with bearing (ball) cover 4, and 4 of bearing 2 and bearing (ball) covers are provided with seal ring 5.When main shaft 1 rotates, because main shaft 1 and seal ring 5 produce friction, after long-time the use, can produce the gap between seal ring 5 and the main shaft 1, affect the sealability of seal ring 5, caused oil leakage, caused the pollution of environment also to cause unnecessary waste simultaneously.
The model utility content
The utility model purpose is the associated sealing arrangement for bearings that a kind of good seal performance is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of associated sealing arrangement for bearings, comprise main shaft, bearing, bearing support, bearing (ball) cover and seal ring, described main shaft is provided with bearing outward, described bearing is provided with bearing support outward, described bearing support outer end is equipped with bearing (ball) cover, is provided with seal ring between described bearing and bearing (ball) cover, has circular groove in the described seal ring; Be filled with gas in the described circular groove.
Preferably, described bearing (ball) cover is connected with bearing support by fastening piece.
Preferably, described fastening piece is countersunk screw.
Preferably, have oil hole on the described bearing support; Described oil hole leads to bearing.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Associated sealing arrangement for bearings of the present utility model, after long-time the use, although produced the gap owing to rub between seal ring and the main shaft, owing to have circular groove in the seal ring, be filled with gas in the circular groove, during the main shaft rotation, frictional heating between seal ring and main shaft, the gas that then is filled with in circular groove meeting expanded by heating, and then so that the seal ring expansion, eliminated the gap between seal ring and the main shaft, improved sealability, that has avoided befouling environment has also avoided unnecessary waste.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the associated sealing arrangement for bearings of prior art;
Accompanying drawing 2 is the structural representation of associated sealing arrangement for bearings of the present utility model;
Accompanying drawing 3 is the sectional view of the A-A of accompanying drawing 2;
Wherein: 1, main shaft; 2, bearing; 3, bearing support; 4, bearing (ball) cover; 5, seal ring; 6, countersunk screw 7, circular groove; 8, oil hole.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of associated sealing arrangement for bearings shown in accompanying drawing 2,3, comprise main shaft 1, bearing 2, bearing support 3, bearing (ball) cover 4 and seal ring 5, the described main shaft 1 outer bearing 2 that is provided with, the described bearing 2 outer bearing supports 3 that are provided with, described bearing support 3 outer ends are equipped with bearing (ball) cover 4, and described bearing (ball) cover 4 is connected with bearing support 3 by fastening piece; Described fastening piece is countersunk screw 6; 4 of described bearing 2 and bearing (ball) covers are provided with seal ring 5, have circular groove 7 in the described seal ring 5; Be filled with gas in the described circular groove 7; Have oil hole 8 on the described bearing support 3; Described oil hole 8 leads to bearing 2.After long-time the use, although produced the gap owing to rub between seal ring 5 and the main shaft 1, but owing to have circular groove 7 in the seal ring 5, be filled with gas in the circular groove 7, during main shaft 1 rotation, 1 frictional heating of seal ring 5 and main shaft, then the gas meeting expanded by heating that is filled with in the circular groove 7, and then so that seal ring 5 expands, eliminated the gap between seal ring 5 and the main shaft 1, improved sealability, that has avoided befouling environment has also avoided unnecessary waste.When changing seal ring 5, unload countersunk screw 6 and just can separate bearing (ball) cover 4 with bearing support 3, then take off old seal ring 5, change new seal ring 5, convenient and swift.Can add lubricant oil to bearing 2 by oil hole 8, reduce the abrasion of bearing 2 and main shaft 1, increase the working life of bearing.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
