Description

Roll shaft sealing structure

Technical field

The utility model is related to conveying device, particularly to a kind of roll shaft sealing structure.

Background technology

Conveyer extensive application in productive life, it is the equipment conveying material aborning, in modern production Middle continuous conveying is indispensable important step in Production line.Ribbon conveyer fed distance is remote, and conveying capacity is big, operation letter Single, reliable operation, thus it is widely used in factory, mine, harbour, down-hole etc..For ribbon conveyer conveyer belt by Carrying roller supports, and conveyer belt moves along carrying roller, and carrying roller does high-speed rotation, because conveyer general work occasion contains more powder Dirt, these dust easily enter in the roll shaft of carrying roller, cause the abrasion of roll shaft, are necessary for changing after abrasion reaches to a certain degree Carrying roller, causes the interruption producing.

Utility model content

For the defect of prior art, the utility model provides a kind of roll shaft sealing structure.

A kind of roll shaft sealing structure, including rotating ring 4 and stationary ring 5, the inner side of described rotating ring 4 is provided with seal ring of moving ring 3, institute State rotating ring 4 and seal ring of moving ring 3 is compressed by annular pressing plate 2, described pressing plate 2 is connected with spring 1, and the outside of described stationary ring 5 sets It is equipped with stationary ring sealing ring 6, described stationary ring 5 and stationary ring sealing ring 6 are fixed on roll shaft by pin key, described stationary ring sealing ring 6 leads to Cross outermost gland 7 to compress, sealed by gland ring 8 between described gland 7 and roll body 9.

The beneficial effects of the utility model are: farthest decrease dust for the impact of axle and bearing it is therefore prevented that Roll shaft caused by dust enters weares and teares so that the service life of roll shaft is improved.

Brief description

Fig. 1 is the schematic diagram of the utility model sealing structure.

Specific embodiment

Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this The specific embodiment of utility model is described in detail, and so that above and other purpose of the present utility model, feature and advantage is incited somebody to action Become apparent from.Identical reference instruction identical part in whole accompanying drawings.Not deliberately accompanying drawing drawn to scale, emphasis It is purport of the present utility model is shown.

As shown in figure 1, a kind of roll shaft sealing structure, including rotating ring 4 and stationary ring 5, the inner side of described rotating ring 4 is provided with rotating ring Sealing ring 3, described rotating ring 4 and seal ring of moving ring 3 are compressed by annular pressing plate 2, and described pressing plate 2 is connected with spring 1, described stationary ring 5 outside is provided with stationary ring sealing ring 6, and described stationary ring 5 and stationary ring sealing ring 6 are fixed on roll shaft by pin key, described stationary ring Sealing ring 6 is compressed by outermost gland 7, is sealed by gland ring 8 between described gland 7 and roll body 9.

In the utility model, rotating ring 4 and stationary ring 5 can be using conventional packing ring, seal ring of moving ring 3, stationary ring sealing rings 6 For rubber ring, by annular pressing plate 2, rotating ring 4 and seal ring of moving ring 3 are compressed to roll shaft, stationary ring 5 and stationary ring sealing ring 6 be not with roller Axle rotates, and rotating ring 4 and seal ring of moving ring 3 can rotate with roll shaft, and spring 1 applies the power of right direction to pressing plate 2, from And rotating ring 4 and stationary ring 5 are combined closely, form end face seal structure, joint portion is provided with oil filler point, penetrate into and combine end face Oil form one layer of oil film, thus playing lubrication, the axial seal of leakage of concluding the business is converted to by this new sealing structure The end face seal of more difficult leakage, serves good sealing effectiveness, gland ring 8 and stationary ring sealing ring 6 can prevent from The liquid leakage that shaft clearance flows out.Decrease dust affects the roll shaft it is therefore prevented that caused by entering due to dust for roll shaft Abrasion is so that the service life of roll shaft is improved.

Elaborate a lot of details in order to fully understand the utility model in the above description.But above description It is only preferred embodiment of the present utility model, the utility model can be come with being much different from alternate manner described here Implement, therefore the utility model is not embodied as being limited by disclosed above.Any those skilled in the art exist simultaneously New to this practicality without departing from the methods and techniques content that the disclosure above under technical solutions of the utility model ambit, all can be utilized Type technical scheme makes many possible variations and modification, or the Equivalent embodiments being revised as equivalent variations.Every without departing from this The content of utility model technical scheme, any simply repaiies to made for any of the above embodiments according to technical spirit of the present utility model Change, equivalent variations and modification, all still fall within the range of technical solutions of the utility model protection.
