This sealing device of new forms of energy actuating system spline lubrication, through setting up the spline chamber, during the reduction gear operation, spline chamber is filled up to a large amount of lubricating grease, and rotatory in-process, lubricating grease produce throttling effect when the clearance that dams through the inflation cavity between the sealed tooth of annular, and lubricating grease is in the inflation cavity to reach the purpose that hinders the hourglass, avoided the device because a series of problems that the oil leak produced.
Description
Technical Field
The utility model belongs to the technical field of sealing device, concretely relates to lubricated sealing device of new forms of energy actuating system spline.
Background
Lubricating grease is generally used for lubricating a connecting spline of a speed reducer and a motor in the current market, and an O-shaped ring is generally used for grease static sealing.
In the design, on one hand, the O-shaped ring is difficult to install at the position, burrs are required to be prevented from scratching the surface of the O-shaped ring, attention is required to be paid during installation, and the O-shaped ring is prevented from falling off during assembly; on the other hand, the temperature is continuously raised along with the continuous increase of the rotating speed of the electric drive system, so that the aging of the O-shaped ring is accelerated. For these reasons, the grease cannot be sealed, and oil leakage occurs.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a sealing device for spline lubrication of a new energy driving system, which has the advantages of good leakage-proof effect, no aging and difficult separation of the device, solves the problems that the O-shaped ring has great installation difficulty at the position, burrs are required to be avoided scratching the surface of the O-shaped ring, and attention is required during installation, and the O-shaped ring is prevented from separating during assembly; in addition, the rotating speed of the electric drive system is continuously increased, the temperature is continuously raised, the aging of the O-shaped ring is accelerated, the lubricating grease cannot be sealed, and the oil leakage phenomenon is caused.
The utility model provides a following technical scheme: the utility model provides a lubricated sealing device of new forms of energy actuating system spline, includes sealing device, sealing device's inside activity has cup jointed the pivot, be equipped with a plurality of annular seal tooth, a plurality of around the pivot be equipped with the inflation cavity between the annular seal tooth, the spline chamber has been seted up to sealing device's inside.
Furthermore, a plurality of the annular sealing teeth are sequentially arranged on the outer surface of the rotating shaft.
Furthermore, the top ends of the plurality of annular sealing teeth are sharp corners, and a series of closure gaps are formed among the plurality of annular sealing teeth.
Further, a plurality of the annular seal teeth are spaced apart by a distance sufficient to allow the expansion cavity to be large enough.
Has the advantages that:
1. this sealing device of new forms of energy actuating system spline lubrication, through setting up the spline chamber, during the reduction gear operation, spline chamber is filled up to a large amount of lubricating grease, and rotatory in-process, lubricating grease produce the throttle effect when the clearance that dams through expansion cavity 4 and annular seal tooth 3 between, and lubricating grease is in the expansion cavity to reach the purpose that hinders the hourglass, avoided the device because a series of problems that the oil leak produced.
2. This lubricated sealing device of new forms of energy actuating system spline through setting up the annular seal tooth, because there is enough distance of beating between the annular seal tooth, and the annular seal tooth is inside through the clearance that dams, and high temperature, high pressure, high-speed and jumbo size are sealed, and the oil leak problem that the ageing oil leak that leads to of O type circle can not take place for the inside of inflation cavity to this sealing device life has been improved, has practiced thrift the cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a sealing device; 2. a spline cavity; 3. an annular seal tooth; 4. the cavity is expanded.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, a sealing device for spline lubrication of a new energy driving system comprises a sealing device 1, a rotating shaft is movably sleeved in the sealing device 1, a plurality of annular sealing teeth 3 are arranged around the rotating shaft, the annular sealing teeth 3 are sequentially arranged on the outer surface of the rotating shaft, the top ends of the annular sealing teeth 3 are sharp corners, the sharp corners face to the gas direction, the annular sealing teeth 3 are thin, the residual speed can be reduced, by arranging the annular sealing teeth 3, because enough beating distance exists between the annular sealing teeth 3, and the inside of the annular sealing teeth 3 passes through a cut-off gap, and by arranging the cut-off gap, when lubricating grease rotates the inside of the annular sealing teeth 3, the outward movement of the lubricating grease is blocked, the sealing is high-temperature, high-pressure, high-speed and large-size sealing, the problem of oil leakage caused by the aging of an O-shaped ring does not occur in the expansion cavity 4, and the service life of, the cost is saved, form a series of clearances that dams between the sealed tooth of a plurality of annular 3, be equipped with inflation cavity 4 between the sealed tooth of a plurality of annular 3, it is enough big that there is certain distance to make inflation cavity 4 between the tooth of a plurality of sealed tooth of annular 3, spline chamber 2 has been seted up to sealing device 1's inside, through setting up spline chamber 2, the reduction gear is during operation, spline chamber 2 is filled up to a large amount of lubricating grease, rotatory in-process, lubricating grease produces the throttle effect when the clearance that dams through between the sealed tooth of inflation cavity 4 and annular 3, lubricating grease is in inflation cavity 4, thereby reach the purpose of hindering the hourglass, a series of problems because the oil leak produced have been avoided the device.
According to the working principle, when the speed reducer operates, a large amount of lubricating grease is filled in the spline cavity 2, in the rotating process, the lubricating grease generates a throttling effect when passing through a flow-stopping gap between the expansion cavity 4 and the annular sealing tooth 3, and the lubricating grease is in the expansion cavity 4, so that oil is not easy to leak.
