Description
Technical field
The utility model relates to a kind of oil scraping plate, particularly about a kind of blower fan main shaft oil scraping plate that is used to remove lubricating grease between blower fan transmission main shaft and buoyancy bearing, transmission main shaft and thrust-bearing.
Background technique
At present, because the sealed precision between transmission main shaft and thrust-bearing and the buoyancy bearing can't guarantee, and the lubricating system between main shaft and bearing adopts lubricating grease to be lubricated, therefore, in the main shaft rotating process, part lubricating grease can flow out from the gap between main shaft and bearing.Because lubricating grease has certain viscosity, its viscosity temperature influence is very big, low more its viscosity of temperature is big more, especially in the winter time, after lubricating grease flows out the oil drip pan that is dropped into below the bearing at once, but can be cumulative on main shaft, the gravity that lubricating grease is stacked into lubricating grease is during greater than the thickness power between lubricating grease, lubricating grease can become the piece drippage, and the volume that falls block grease this moment will far surpass the oily space that connects of oil drip pan reservation, fall the oil drip pan outside so have a big chunk drip of grease, and lubricating grease has certain corrosivity, can cause to a certain degree damage to equipment when lubricating grease drops onto oil drip pan outside, influence the working life of equipment; When lubricating grease drops onto on ladder and the pedal, understand serious threat repair and maintenance personnel's the security of the lives and property.But because the assembling and the restriction of some other factors, the size of the oil drip pan below the main shaft bearing can not enlarge again, moreover if change the oil drip pan that has moved blower fan, because factor such as the space is narrow and small, its work difficulty coefficient is bigger, and needs the expense of great number.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of simple in structure, with low cost, and is easy for installation and can improve the blower fan main shaft oil scraping plate that oil drip pan connects oily effect.
For achieving the above object, the utility model is taked following technological scheme: a kind of blower fan main shaft oil scraping plate, it is characterized in that: it comprises that one is used to keep off the oil guide plate that oily oil baffle and is used for Oil Guide, described oil baffle and described oil guide plate are one-body molded, and form a slyness " V " shape oil guide slot between described oil baffle and the described oil guide plate, the arranged outside of described oil guide plate has a mounting arm that is used to install, and offers an opening on the described mounting arm; The top of described oil guide plate is provided with a seam shape and scrapes pasta.
Scrape of top with the described blower fan main shaft corresponding curved setting of the seam top of pasta by described seam shape to described oil baffle.
Seam and described blower fan main shaft outer that described seam shape is scraped pasta have the gap, and described gap length is between 0.5mm～1mm.
Described oil baffle, oil guide plate and mounting arm all adopt the steel plate panel beating to make.
It is that 1mm, model are that the steel plate panel beating of Q235 is made that described blower fan main shaft oil scraping plate adopts thickness.
The utility model is owing to take above technological scheme, it has the following advantages: 1, the utility model is owing to adopt oil baffle and oil guide plate integrated formed structure, and form a slyness " V " shape oil guide slot between the two, also be provided with a mounting arm that has an opening in the outside of oil guide plate, the utility model be bolted on the oil drip pan by mounting arm.Therefore, realized that the utility model is simple in structure, and characteristics such as cost is lower.2, the utility model only needs during installation fixing bolt is unclamped owing to adopt the split bolt of mounting arm to be fixedly mounted on the oil drip pan, and mounting arm is inserted oil drip pan by this opening, screws bolt then and gets final product; And, can adjust position of the present utility model up and down by this mounting arm opening, make and leave suitable gap between the utility model and the blower fan main shaft, therefore, realized easy for installationly, simultaneously, realized better frizing effect.3, therefore the utility model, has further guaranteed frizing effect of the present utility model owing to adopt oil baffle to prevent the grease overflow outside oil scraping plate that scrapes.4, therefore the utility model, has improved the oily effect of connecing of oil drip pan effectively owing to adopt oil guide plate and oil guide slot that the grease that scrapes is directly imported in the oil drip pan.5, therefore the utility model, can further improve frizing effect of the present utility model owing to adopt the seam shape to scrape the seam of pasta and the gap that the blower fan main shaft outer has 0.5mm～1mm.The utility model can be widely used in the wind-power electricity generation industry.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
The utility model is used for the blower fan main shaft frizing, oil drip pan inside strake, the outer scraper plate of preceding oil drip pan, back oil drip pan inside strake and outer scraper plate four samples of back oil drip pan before a cover oil scraping plate comprises, and its structure is identical, and oil scraping plate is an example in the former oil drip pan.
As shown in Figure 1 and Figure 2, the utility model comprises that one is used to keep off the oil guide plate 2 that oily oil baffle 1 and is used for Oil Guide, oil baffle 1 is one-body molded with oil guide plate 2, and form a slyness " V " shape oil guide slot 3 between oil baffle 1 and the oil guide plate 2, the grease that imports is directly imported in the preceding oil drip pan of the prior art.The arranged outside of oil guide plate 2 has a mounting arm that is used to install 4, offer an opening 5 on the mounting arm 4, be used for mounting arm 4 being fixed to oil drip pan before the blower fan, make when mounted by fixing bolt, only fixedly the bolt of oil drip pan unclamps the insertion oil scraping plate, screws bolt then and gets final product; And can adjust mounting point of the present utility model by this opening 5.The top of oil guide plate 2 is provided with a seam shape and scrapes pasta 6, makes between blower fan main shaft oil scraping plate of the present utility model and the blower fan main shaft and leaves suitable gap, to reach better frizing effect.
In the foregoing description, the seam top of being scraped pasta 6 by the seam shape is to the corresponding curved setting with blower fan main shaft of the top of oil baffle 1 (as shown in Figure 2), and the top of each oil scraping plate all according to its position of using separately corresponding with the shape of corresponding frizing side bearing outer be provided with curved.
In the various embodiments described above, seam and blower fan main shaft outer that the seam shape is scraped pasta 6 have the gap, and this gap length is between 0.5mm～1mm, and then can play frizing effect preferably.
