Description
Technical field
The utility model belongs to seal arrangement field, particularly relates to a kind of improvement about pinch roller output shaft end seal arrangement.
Background technique
Fig. 1 is the structural representation of existing output shaft end seal arrangement.As shown in Figure 1, existing pinch roller output shaft end main parts size comprises: 1, pinch roller, and 2, seal ring, 3, output shaft, 4, bearing.Owing to when pinch roller 1 works being and high temperate zone steel Long contact time, so have cool water shower pinch roller 1, now have water arrives seal ring 2 position from the gap between pinch roller 1 and output shaft 3 unavoidably, at the equipment use initial stage, by the effect of seal ring, these water also can not enter the position of bearing 4, but along with the long-time use of equipment, seal ring 2 just there will be aging, wearing and tearing, seal failure, just have the position that water enters bearing 4, burn out a bearing, cause stopping production.Producing for keeping away ease impact, standby a large amount of seal ring 2 need be purchased and regularly replace.
Summary of the invention
The utility model, for above-mentioned technical problem, provides a kind of improvement about pinch roller output shaft end seal arrangement, makes output shaft end reach water proof and dust proof suburb fruit completely, can not occur the phenomenon that output shaft end burns out because of water inlet bearing again.
The technological scheme that the utility model adopts is:
A kind of improvement about pinch roller output shaft end seal arrangement, it is characterized in that: comprise pinch roller, mechanical seal, output shaft, bearing, fixed base, gland, water holding ring, described bearing is installed in described fixed base, described pinch roller is arranged at the side of described fixed base, one end of described output shaft is installed in described bearing and its other end is installed in described pinch roller, described gland is sheathed on the outside of described output shaft and it is arranged at described pinch roller, between fixed base, described gland by bolt-locking on described fixed base and its bearing is compressed, outside the middle part that described mechanical seal is installed on described output shaft and it covers at the inside of described pinch roller, described mechanical seal comprises inner sleeve, overcoat, it is interference fit between described inner sleeve and output shaft, described overcoat is fixed on the outside of described inner sleeve and its opening end is arranged towards described gland, described water holding ring is sheathed on the outside of described inner sleeve, one end of described water holding ring is fixed on described gland and its other end is inserted in described overcoat.
The connection part of described inner sleeve, overcoat adopts welding manner.
The connection part of described water holding ring, gland adopts welding manner.
The beneficial effects of the utility model are:
1, original seal ring mechanical seal is replaced, it is interference fit between the inner sleeve of mechanical seal and output shaft, the water flowed down from pinch roller can be thrown away by the slinger ring of mechanical seal, water holding ring between inner sleeve, overcoat also has the effect of dash, multiple water proof and dust proof, thus the generation greatly reducing burn-out of bearing situation;
2, equipment user purchases a large amount of seal rings without the need to standby again, also without the need to regularly replacing seal ring, only needs conventional regular maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing output shaft end seal arrangement;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
In figure, 1-pinch roller, 2-seal ring, 3-output shaft, 4-bearing, 5-mechanical seal, 6-fixed base, 7-gland, 8-water holding ring, 9-bolt, 10-inner sleeve, 11-overcoat.
Embodiment
As shown in Figure 2, a kind of improvement about pinch roller output shaft end seal arrangement, comprise pinch roller 1, mechanical seal 5, output shaft 3, bearing 4, fixed base 6, gland 7, water holding ring 8, bearing 4 is installed in fixed base 6, pinch roller 1 is arranged at the side of fixed base 6, one end of output shaft 3 is installed in bearing 4 and its other end is installed in pinch roller 1, gland 7 is sheathed on the outside of output shaft 3 and it is arranged at pinch roller 1, between fixed base 6, gland 7 to be lock onto on fixed base 6 by bolt 9 and bearing 4 compresses by it, outside the middle part that mechanical seal 5 is installed on output shaft 3 and it covers at the inside of pinch roller 1, mechanical seal 5 comprises inner sleeve 10, overcoat 11, it is interference fit between inner sleeve 10 and output shaft 3, overcoat 11 is fixed on the outside of inner sleeve 10 and its opening end is arranged towards gland 7, water holding ring 8 is sheathed on the outside of inner sleeve 10, one end of water holding ring 8 is fixed on gland 7 and its other end is inserted in overcoat 11.
The connection part of inner sleeve 10, overcoat 11 adopts welding manner.
The connection part of water holding ring 8, gland 7 adopts welding manner.
Seal ring 2 original in Fig. 1 is replaced with the mechanical seal 5 in Fig. 2, do not re-use the rubber seal in Fig. 1, aging, wear phenomenon would not be occurred again, thus the problem of burn-out of bearing before solving, greatly reduce production maintenance expense, reduce cost of production.
Above 1 embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
