Abstract
The utility model discloses a vertical shaft oil baffle disc sealing assembly which is applicable to lubricating and sealing of a speed reducer and a speed increaser. The vertical shaft oil baffle disc sealing assembly comprises a gear box shell and an oil seal which is fixed on a vertical shaft, and is characterized in that oil baffle disc which is in a circular-disc-shaped umbrella-type structure is sleeved on the vertical shaft at the upper part of the oil seal; an annular oil groove is formed in the bottom of the gear box shell and an oil leaking opening is formed in the bottom of the annular oil groove; and the oil leaking opening is connected with a lubricating oil tank through an oil reflowing pipe. The vertical shaft oil baffle disc sealing assembly disclosed by the utility model is reasonable in design and novel in structure; the vertical shaft oil baffle disc sealing assembly can effectively prevent the oil seal from being aged, prolongs the service life and solves the problems that vertical shaft (a transmission shaft) lubricating seals of the speed reducer, the speed increaser and the like have oil leakage; the maintenance frequency is reduced and the operation cost is reduced; and the vertical shaft oil baffle disc sealing assembly can be widely used in the lubricating seals of the speed reducer, the speed increaser and a hydraulic system.
Description
Technical field
The utility model relates to the transmission shaft lubrication technical field, specifically a kind of lubrication and seal system that is applicable to vertical shaftes such as the matching used speed reducer of extra-large-size vertical-shaft wind power generation device, booster engine.
Background technique
At present, the transmission shaft lubrication and seal of speed reducer, booster engine and some hydraulic systems adopts the direct sealing means of outside framework oil seal usually.Yet in vertical shaft lubrication and seal process, the oil sealing leakage of oil is a difficult problem that never solves for a long time.On the one hand, because the vertical shaft high speed rotating, the long-time high-speed friction of oil sealing and vertical shaft increases because of wearing and tearing cause the gap of oil sealing; On the other hand, this oil sealing long period of soaking has been quickened the aging of oil sealing in lubricant oil, and sealability reduces.Above-mentioned two factors make the lubricant oil that gets rid of in the gear-box along releasing through oil sealing under the vertical axial and leakage of oil occurs.Therefore, the existing employed oil sealing of transmission shaft lubrication and seal just needs to change once general every half a year, has not only increased maintenance frequency and difficulty, and has increased operating cost.In order to solve transmission shaft lubrication and seal leakage of oil problem, two oil sealings of overlapping installation on vertical drive shaft that have, the dual-thread seal section that lengthening is set on vertical drive shaft that has, what have installs a flinger ring again in the oil sealing bottom.Though these measures have been played certain effect to solving the oil sealing leakage of oil, have ignored " leading " owing to biasing toward " blocking up ", thereby have been difficult to fundamentally solve the leakage of oil problem of vertical drive shaft lubrication and seal.
Summary of the invention
In order to overcome the deficiency of vertical shaft lubrication and seal leakage of oil technology, it is a kind of simple in structure that the utility model provides, and favorable sealing property can solve the vertical shaft oil baffle disc black box of lubrication and seal leakage of oil effectively.
The technical solution adopted in the utility model is: this vertical shaft oil baffle disc black box, comprise gear box casing and be fixed on oil sealing on the vertical shaft, it mainly is the oil baffle disc that on the vertical shaft on oil sealing top, is set with beveled structure in the form of annular discs, the outside diameter of oil baffle disc is more than or equal to the outside diameter of oil sealing, be provided with annular oil groove in the gear box casing bottom, the annular oil groove bottom is provided with oil leakaging port, and oil leakaging port connects lubricating oil tank by return tube.
As a kind of improvement of the present utility model, the outer circumferential edge of described oil baffle disc is made as upwarps structure, and on the edge that upwarps, be provided with the downward flanging of a circle, on oil baffle disc, constitute the oil groove of band flanging.
The utility model major advantage compared with prior art is reasonable in design, good sealing effect.At first owing to be provided with annular oil groove in gear box casing bottom, make oil sealing be in all the time lubricant oil above, avoid oil sealing to be immersed in for a long time in the lubricant oil, prevent that oil sealing is aging, prolonged the working life of oil sealing.Secondly, owing to be provided with oil baffle on oil sealing, the lubricant oil that is thrown out of drops on the oil baffle, produces under the action of centrifugal force at the vertical shaft high speed rotating, the lubricant oil that is blocked by oil baffle disc directly enters in the annular oil groove along the gear box casing wall, rather than flows to oil sealing along vertical shaft.Lead in conjunction with a difficult problem that has solved vertical shaft (transmission shaft) lubrication and seals such as speed reducer, booster engine effectively by stifled, reduce maintenance frequency, reduced cost of production.
