Abstract
The utility model relates to a water accumulation proof and oil leakage proof ventilation structure of a gearbox. A eyehole cover is arranged on the wall of the box body; a ventilation cover component is arranged on the eyehole cover, wherein, the ventilation cover component comprises a cover body, a space ring, a copper meshwork and a connecting cap; a labyrinth oil guarding structure is arranged on the internal wall, wherein, the oil guarding structure comprises two U-shaped oil guarding plates arranged in a cross pattern. The utility model takes into consideration and solves the problems of water accumulation, oil leakage and ventilation of the gearbox, is particularly applicable to a rolling mill in abominable working conditions, and is capable of achieving the desired objectives with good effects no matter when the rolling mill is in a horizontal or a vertical working mode.
Description
Technical field
The utility model relates to a kind of gear box structure, the gear-box ventilating structure of especially a kind of not only anti-ponding but also anti-leakage of oil.
Background technique
In gear box arrangement, because the gear in the casing in the engagement driving process, makes temperature and the hurried rising of air pressure in the casing 1, thus ventilating structure must be set, to reach the exhaust decompression purpose.Remove this, gear can make the oily foam that splashes directly enter the ventilating cover endoporus in operation process owing to get rid of oily direction randomness in the casing, when hot air flow when ventilating cover is discharged, also taken oily foam out of simultaneously and caused oil liquid leakage, polluted casing and environment.Especially rolling machinery, work under bad environment, aqueous vapor, dust is heavy, cause the outer ponding laying dust of ventilating cover, have a strong impact on air permeable effect, and milling train casing outside does not have the space all around, ventilating cover protrudes cabinet exterior can not surpass 30mm, originally ventilating cover is mounted in and satisfies space constraints on the inspection hole cover 3 of recessed tank wall, as shown in Figure 1, but easily makes the cooling water that is cast on the rolling mill roll produce ponding at these groove 2 places, and milling train is a bevel gear drive, its working state can be the level of state, and also can turn clockwise 90 ° in vertical state, when sentencing plumbness work, ponding in the groove 2 will enter in the casing, how therefore the serious gear that corrodes, solve the ponding of milling train gear-box, leakage of oil, ventilative problem is the task of top priority.
Summary of the invention
Technical problem to be solved in the utility model all provides a kind of anti-leakage of oil ventilating structure of the anti-ponding of gear-box with anti-ponding, anti-leakage of oil, good permeability in the defective that overcomes prior art.
Described technical problem solves with following technical proposal:
The anti-leakage of oil ventilating structure of the anti-ponding of a kind of gear-box is provided with inspection hole cover on box body wall, inspection hole cover is provided with the ventilating cover assembly, it is characterized in that described inspection hole cover inwall is provided with the mazy type oil baffle structure.
Described ventilating cover assembly is made up of cover body, spacer ring, copper mesh, attachment cap.
Described mazy type oil baffle structure is " ten " word by two " U " type oil baffles and intersects layout and solid welding at the inspection hole cover inwall.
Described inspection hole cover flushes installation with cabinet exterior.
The utility model has improved the mounting structure and the ventilating cover modular construction of inspection hole cover, makes no matter gear-box is horizontal operation state or vertical working state, can not cause ponding; Simultaneously set up the mazy type oil baffle structure at the inspection hole cover inwall, block the oily foam that splashes and entered the ventilating cover endoporus, both avoid ventilating cover ponding laying dust and influenced air permeable effect, solve oil liquid leakage again and polluted casing and problem of environment, comprehensively solve ponding, leakage of oil and the ventilative problem of milling train gear-box, had more reliable and more stable ventilative anti-leakage of oil effect.
Description of drawings
Fig. 1 is a prior art gear box structure schematic representation.
Fig. 2 is the utility model gear box structure schematic representation.
Fig. 3 is the ventilating cover assembly assumption diagram.
Fig. 4 is mazy type oil baffle structure figure.
Fig. 5 is the sectional view of Fig. 4.
Embodiment
Embodiment is specifically described the utility model again below in conjunction with accompanying drawing.
Shown in Fig. 2～5, the anti-leakage of oil ventilating structure of the anti-ponding of gear-box is processed counterbore on the outer wall of gear housing 1, inspection hole cover 3 usefulness screws are fixed in the counterbore, and it is flushed with cabinet exterior, and no groove 2 structures reach little space purpose and avoid ponding.Ventilating cover assembly 4 is made up of cover body 6, spacer ring 7, copper mesh 8 and attachment cap 9, and is threaded on inspection hole cover 3 outer walls by attachment cap.Simultaneously be provided with mazy type oil baffle structure 5 at inspection hole cover 3 inwalls, this structure is made up of two small one and large one " U " type oil baffles 10, and be the solid welding of " ten " word intersection layout on the inspection hole cover inwall, block the oily foam that splashes and directly enter the vent hood endoporus, avoid causing the outer ponding laying dust of ventilating cover and influence ventilative, mazy type oil baffle structure 5 has also been avoided casing leakage of oil problem simultaneously, guarantees that gear obtains good lubrication.
Ponding, leakage of oil and the ventilative problem of gear-box taken all factors into consideration and solved to the utility model, suitable especially being applied on the abominable milling train gear-box of work condition environment, no matter milling train is the horizontal operation state or turns clockwise 90 ° by accompanying drawing 1 and is vertical working state, can both accomplish the end in view, learn to have preferably anti-ponding, reliable and stable ventilative, anti-leakage of oil effect by The field.
