Description

A kind of strip steel trident area pinch roll reduction gear oil tank waterproof seal
Technical field
This utility model is related to a kind of strip steel trident area pinch roll reduction gear oil tank waterproof seal, belongs to metallurgy industry Strip steel equipment technical field.
Background technology
It is that strip steel goes out most important plant equipment after finishing mill line that strip steel trident area pinches equipment, and strip steel is needed through pinching The pinch and guiding of equipment, by directing on connecting plate for strip steel safety, pinch equipment plays the role of to form a connecting link, thus right Pinch equipment proposes very high request.In pinch equipment, reductor is emphasis equipment therein again, this and pinch equipment institute itself The environment at place and reductor this body structure have very big relation, and trident area has substantial amounts of cooling water to drop to upset guide groove and pinch roll Temperature, it may be said that The water splash in all directions, in pinch equipment, Reducer is 90 ° of input/output structures, that is, level input and Vertical output, this just proposes higher requirement to the bearing position sealing at vertical output position, prevents the cooling water that The water splash in all directions Enter at bearing by speed reducer output shaft position in reduction gear oil tank, if cooling water is entered in reduction gear oil tank, meeting Oil and water mixing in reductor are caused, bearing lubrication effect is had a strong impact on, is finally easily occurred in the case of equipment runs up Bearing locking equipment breakdown, causes trident area piling of steel accident, affects the rolling rhythm of steel rolling, declines steel rolling production capacity, while axle Burning for holding also increases spare parts consumption expense.
The sealing device of the output end of reducer bearing position in existing trident area pinch equipment is installed by shaft end Individual oil sealing plays water seal effect, and the effect of the initial period water seal of the water seal arrangement installation of this structure is fine but left using 20 days Begin to seepy question occur after the right time, because oil sealing weares and teares larger during axle rotates at a high speed, while oil sealing pair Rotary shaft also has different degrees of abrasion, and the ditch of abrasion will be formed between such oil sealing and rotary shaft, and cooling water will lead to The fray crossed between oil sealing and axle is penetrated in reduction gear oil tank, causes bearing lubrication bad, in the case where bearing rotates at a high speed, is burnt The situation for ruining bearing happens occasionally.
Utility model content
This utility model purpose is to provide a kind of strip steel trident area pinch roll reduction gear oil tank waterproof seal, by anti- Water jacket, bucker and felt collar oil sealing, form three-level sealing, solve problem present in background technology.
The technical solution of the utility model is:
A kind of strip steel trident area pinch roll reduction gear oil tank waterproof seal, comprising pinch roll, waterproof jacket, bucker, Bucker bolt, felt collar oil sealing cover, felt collar oil sealing, output end of reducer bearing gland and bearing gland bolt, waterproof jacket are solid It is scheduled on the inside of the lower section of pinch roll, plays primary seal effect, bucker is bolted to output end of reducer by bucker On bearing gland, secondary seal effect is played, is located above bucker in waterproof jacket, is set on output end of reducer bearing gland There is felt collar oil sealing, felt collar oil sealing plays three-level sealing function, and output end of reducer bearing gland is fixed by bearing gland bolt On pinch roll reductor.
The output end of reducer bearing gland is provided with groove, and felt collar oil sealing is located on output end of reducer bearing gland Groove in, felt collar oil sealing is provided with felt collar oil sealing cover, and felt collar oil sealing cover is bolted to connection with bucker.
The cylindrical shape in the top of the waterproof jacket and bucker, the external diameter of the top of bucker are interior less than waterproof jacket Footpath.
Using this utility model, waterproof jacket blocks the part cooling water and dust of surrounding, serves one-level water proof and dust proof Effect.Bucker blocks part cooling water and the dust that waterproof jacket can not stop, plays two grades of water proof and dust proof effects, felt collar Oil sealing is to stop steam and the micronic dust come in gap of the very small amount between waterproof jacket and bucker, playing three-level waterproof Dustproof effect, realizes the pinch roll reduction gear oil tank three-level sealing of trident area.
The beneficial effects of the utility model are:Solve the problems, such as the pinch roll reduction gear oil tank water inlet of strip steel trident area, drop The low consumption of trident area pinch roll bearing in reduction gears, reduces the labor intensity of maintainer, reduces in the operation of rolling Production accident.

Specific embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1, a kind of strip steel trident area pinch roll reduction gear oil tank waterproof seal, comprising pinch roll 1, waterproof Set 3, bucker 4, bucker bolt 5, felt collar oil sealing 7, output end of reducer bearing gland 8 and bearing gland bolt 9, waterproof jacket 3 are fixed on the inside of the lower section of pinch roll 1, play primary seal effect, and bucker 4 is fixed on reductor by bucker bolt 5 On outfan bearing gland 8, secondary seal effect is played, the top of bucker 4 is located in waterproof jacket 3, output end of reducer axle Pressure cap 8 is provided with felt collar oil sealing 7, and felt collar oil sealing 7 plays three-level sealing function, and output end of reducer bearing gland 8 passes through axle Pressure-bearing bonnet bolt 9 is fixed on pinch roll reductor.
In the present embodiment:
Referring to the drawings 3, the cylindrical shape in top of accompanying drawing 4, waterproof jacket 3 and bucker 4, outside the top of bucker 4 Internal diameter of the footpath less than waterproof jacket 3.Waterproof jacket 3 directly blocks the part cooling water and dust of surrounding, serves one-level waterproof and prevents Dirt is acted on.The top of waterproof jacket 3 and bucker 4 is overlapping, and leaves certain interval, and such bucker 4 just blocks waterproof Part cooling water and dust that set 3 can not stop, play two grades of water proof and dust proof effects.
Referring to the drawings 5, accompanying drawing 6, output end of reducer bearing gland 8 is provided with groove, and it is defeated that felt collar oil sealing 7 is located at reductor In the groove gone out on end bearing gland 8, felt collar oil sealing 7 is provided with felt collar oil sealing cover 6, and felt collar oil sealing 7 passes through felt collar oil sealing pressure Lid 6 uses bolt presses with bucker 4.Felt collar oil sealing 7 stops what gap of the very small amount between waterproof jacket and bucker was come in Steam and micronic dust, play the effect of three-level water proof and dust proof, realize the pinch roll reduction gear oil tank three-level sealing of trident area, solve and subtract The problem of fast sump water inlet.
