The composite surface comprises an annular inclined surface close to the edge of the oil slinger and an annular arc surface close to the rotating shaft, and the arc surfaces are respectively tangent to the inclined surface and the circumferential surface of the rotating shaft. The included angle between the inclined plane and the vertical plane of the oil slinger is 30 degrees. The utility model relates to a high-speed gear box oil blanket structure, its simple structure of this high-speed gear box oil blanket structure, economy is suitable for, can effectively improve the oil blanket effect of high-speed gear box, has protected operational environment, has practiced thrift the oil cost.
Description
Technical Field
The utility model belongs to the technical field of the oil seal, especially, relate to a high-speed gear box oil blanket structure.
Background
The high-speed gear box is widely applied to the industries of petrifaction, electric power, steel, spinning, environmental protection, biological pharmacy and the like. With the development of scientific technology, the requirements on high-speed gearboxes are higher and higher, namely: higher speeds and powers are required, as well as smaller sizes. The sealing performance of the high-speed gearbox for sealing oil is correspondingly improved. The main disadvantages of the currently commonly used oil seal structure are: the side of oil slinger is the plane, and at the high-speed operation in-process of rotor, the oil that oil slinger throws away still splashes and spills the both sides at the oil slinger, promptly: one side in the gear box and one side of atmosphere, its oil blanket effect is not fully satisfactory.
SUMMERY OF THE UTILITY MODEL
In order to solve the existing problem, the utility model provides a high-speed gear box oil blanket structure, its simple structure of this high-speed gear box oil blanket structure, economy is suitable for, can effectively improve the oil blanket effect of high-speed gear box, has protected operational environment, has practiced thrift the oil cost.
In order to achieve the above object, the present invention adopts the following technical solutions, including:
the oil seal is sleeved on the rotating shaft, a plurality of comb teeth are axially arranged on the oil seal, a plurality of annular raised oil slingers are axially arranged on the rotating shaft, the comb teeth are matched with the oil slingers, and the side face of one side of the oil slingers, close to the atmosphere, is a composite face.
The composite surface comprises an annular inclined surface close to the edge of the oil slinger and an annular arc surface close to the rotating shaft, and the arc surfaces are respectively tangent to the inclined surface and the circumferential surface of the rotating shaft.
The included angle between the inclined plane and the vertical plane of the oil slinger is 30 degrees.
The utility model relates to a high-speed gear box oil blanket structure, its simple structure of this high-speed gear box oil blanket structure, economy is suitable for, can effectively improve the oil blanket effect of high-speed gear box, has protected operational environment, has practiced thrift the oil cost.

Fig. 1 is a schematic view of the present invention in a partial sectional structure.
Fig. 2 is an enlarged schematic view of a portion I of fig. 1.
Fig. 3 is a schematic diagram of the oil slinger of the present invention.
FIG. 4 is a schematic diagram of oil slinger slinging in a crude oil seal configuration.
Detailed Description
In order to make the skilled in the art have a clear understanding of the present invention, a brief introduction is first made to the crude oil seal structure, as shown in fig. 4, in the crude oil seal structure, the slinger 13 on the rotating shaft 11 is matched with the comb teeth on the oil seal 12, but because the side of the slinger close to the atmosphere side is a plane, after the oil thrown out by the slinger touches the inner cavity of the oil seal, a part of the oil is still splashed on the side of the slinger close to the atmosphere (as shown by the arrow in fig. 4), therefore, the effect of the oil seal is not satisfactory.
The present invention will be described in further detail with reference to the accompanying drawings, as shown in fig. 1 and fig. 2, the present invention includes:
the oil seal 2 is sleeved on the rotating shaft 1, a plurality of comb teeth are axially arranged on the oil seal, a plurality of annular raised oil slingers 3 are axially arranged on the rotating shaft, the comb teeth are matched with the oil slingers, and the side faces, close to the atmosphere, of the oil slingers are composite faces.
The composite surface comprises an annular inclined surface 4 close to the edge of the oil slinger and an annular arc surface 5 close to the rotating shaft, and the arc surfaces are respectively tangent with the inclined surface and the circumferential surface of the rotating shaft.
Further, the included angle between the inclined plane and the vertical plane of the oil slinger is 30 degrees.
As shown in fig. 3, in operation, the side surface of the oil slinger close to the atmosphere side is a composite surface, namely: due to the combination of the annular inclined plane and the annular arc surface, most of oil thrown out by the oil slinger is splashed to one side (shown by an arrow in figure 3) of the oil slinger close to the gear box after contacting the inner cavity of the oil seal, so that the oil seal effect is greatly improved.
The utility model relates to a high-speed gear box oil blanket structure, its simple structure of this high-speed gear box oil blanket structure, economy is suitable for, can effectively improve the oil blanket effect of high-speed gear box, has protected operational environment, has practiced thrift the oil cost.
