Abstract
The utility model relates to a sealing device for a rolling mill stand roller bearing. A spacer sleeve is arranged at a roller diameter part of an inner side rolling mill stand roller of a bearing seat; a labyrinth type seal which has the effect of a first layer seal is arranged at one end of the spacer sleeve, which is close to the roller; a penetration cover is arranged on the inner side of the bearing seat; a lip-shaped rotary seal which has the effect of a second layer seal is mounted at one end of the penetration cover, which is close to the roller; and a double-lip-shaped rotary seal which has the effect of a third layer seal is mounted at one end of the penetration cover, which is close to the bearing. According to the sealing device disclosed by the utility model, a plurality of layers of the seals are arranged so as to prevent water and iron oxide powder from entering the stand roller bearing and guarantee an operation environment of the bearing; and therefore, the service life of the bearing is prolonged.
Description
Technical field
The utility model belongs to the seal arrangement technical field, relates to a kind of roll mill associated sealing arrangement for bearings that hot rolled steel plate factory uses that is applicable to.
Background technique
In hot rolled steel plate factory; roll mill plays vital effect; slab is sent here from rollgang; sending operation roll of mill to by breast roll is rolled; in case the breast roll bearing breaks down; breast roll can't normal rotation, directly causes slab can't normally be delivered into operation roll of mill, and then causes rolling mill fault to be shut down.Breast roll is installed in mill housing inside, is positioned on the machine near the descaling header, bears for a long time the impact of de-scaling high pressure water, in case poor sealing, high pressure water will enter bearing support, also can be mingled with some brown iron oxides simultaneously, directly affects bearing working life.Therefore, the sealing effect of roll mill just seems most important.
The model utility content
In order to overcome the above-mentioned shortcoming of prior art
,It is a kind of by multi-sealed that the utility model provides, and do not intake when guaranteeing bearing operation and the impurity such as brown iron oxide, improves the bearing roll mill associated sealing arrangement for bearings in working life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of roll mill associated sealing arrangement for bearings, directly locate to be provided with spacer sleeve at the inboard breast roll roller of bearing support, and spacer sleeve roller rest end has been provided with the labyrinth sealing of first layer seal action; In the bearing support installed inside transparent cover is arranged, transparent cover roller rest end has been equipped with the lip rotary seal of second layer seal action; The double-lipped rotary seal of three-layer sealed effect has been installed by bearing end in the transparent cover.
Described double-lipped sealing is installed in the double-lipped sealing installation position of transparent cover, and the double-lipped sealing is fixed with pressure ring, and bolt is installed in fixed pressure ring in the gland bolt hole.
Described bearing and bearing support are installed on the breast roll.
In the spacer sleeve O of described spacer sleeve type ring recess, spacer sleeve O type circle is installed.
Transparent cover O type circle is installed in the transparent cover O of described transparent cover ring recess.
The beneficial effects of the utility model are: by multi-layer sealed, avoid breast roll bearing water inlet and brown iron oxide, guarantee bearing running environment, thereby improve bearing working life.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, Fig. 2 and Fig. 3,
A kind ofThe roll mill associated sealing arrangement for bearings is equipped with spacer sleeve 9 at breast roll 7, and transparent cover 4 installs on the spacer sleeve 9, and bearing 2 is installed in the bearing support 1, and bearing 2 and bearing support 1 are installed to again on the breast roll 7, with screw 12 transparent cover 4 and bearing support 1 is connected and fixed again; Transparent cover O type circle 3 is installed in the transparent cover O ring recess 16 of transparent cover 4,17 places, single lip seal installation position are equipped with lip seal 10, double-lipped sealing 18 places, installation position are equipped with double-lipped rotary seal 11, and then with pressure ring 5 that double-lipped sealing 11 is fixing, bolt 6 is installed in fixed pressure ring 5 in the gland bolt hole 15; In the spacer sleeve O type ring recess 14 of spacer sleeve 9 spacer sleeve O type circle 8 is installed; Thereby realize the multi-sealed of bearing.
The inboard breast roll roller of bearing support of the present utility model directly locates to be provided with spacer sleeve, and spacer sleeve roller rest end has labyrinth sealing, when the breast roll High Rotation Speed, most of water can be got rid of, and this is the first layer sealing; Transparent cover of bearing support installed inside, transparent cover roller rest end is installed a lip rotary seal, and after bearing and bearing support were installed on the roller, this lip rotary seal cooperated with spacer sleeve, formed second layer sealing; By bearing end double-lipped rotary seal is installed in the transparent cover, lip rotary seal is bolted by pressure ring and prevents from walking, and after bearing and bearing support were installed on the roller, double-lipped rotary seal cooperated with spacer sleeve, forms the three-layer sealed.In addition, between spacer sleeve and roller, the surface of contact between transparent cover and bearing support has again the sealing of O type circle.
The utility model is avoided the water inlet of breast roll bearing and brown iron oxide by multi-layer sealed, guarantees bearing running environment, thereby improves bearing working life.
