Technical Field
The utility model relates to the field of sealing devices, in particular to an inter-shaft sealing structure.
Background
In the rotating shaft, lubricating oil is used for reducing friction, so that the rotating shaft is more flexible. In order to avoid leakage of oil during rotation of the shaft, a sealing device is required.
In the prior art, the seal of the rotating shaft is usually provided at the end of the shaft from which it protrudes, i.e. at the edges or joints, by means of sealing means. However, the sealing process is excessively complicated to install, the position is confirmed firstly, and then the rotating shaft is installed in a sealed manner, so that the operation is troublesome; the sealing effect is unstable.
Disclosure of Invention
The present utility model provides an inter-shaft sealing structure to solve the above-mentioned problems in the prior art.
In order to solve the problems, the utility model adopts the following technical scheme: the utility model provides an interaxial seal structure, includes outer revolving axle, outer revolving axle internal rotation is installed to outer revolving axle internal rotation, install the sealing ring between outer revolving axle inner wall and the inner revolving axle outer wall, the port of outer revolving axle is provided with the oil slinger with the junction of inner revolving axle, be provided with on the outer wall of outer revolving axle and wrap up the oil slinger and with the long-pending oil tank of inner revolving axle adaptation, one side interval that keeps away from the sealing ring on the inner revolving axle outer wall is provided with sealed comb tooth.
Compared with the prior art, the utility model has the beneficial effects that: through the setting of sealing ring, oil slinger, sealed comb tooth isotructure, make this device not only simple to operate, through the pressure effect between oil slinger and the sealed comb tooth moreover, the sealed and lubricated effect of this structure is better.
As a further improvement of the present utility model, the technical problem to be solved is: the oil leakage and oil discharge direction of the device are difficult to control.
In order to solve the technical problems, the utility model further adopts the following technical scheme: the inner wall of the outer rotary shaft is in a taper hole shape.
The beneficial effects of the improvement are as follows: through the arrangement of the taper hole shape, the device can control the oil drainage direction of the leaked lubricating oil between the two rotating shafts.
As a further improvement of the present utility model, the technical problem to be solved is: the manner of installation and mating between the sump and the slinger requires further ease of mating, while preventing the slinger from carrying the oil to an excessive location.
In order to solve the technical problems, the utility model further adopts the following technical scheme: an oil retaining washer is arranged on the outer wall of the inner rotary shaft between the oil accumulation box and the oil slinger.
The beneficial effects of the improvement are as follows: through the setting of oil retaining washer, make this device can make things convenient for the installation between long-pending oil tank and the oil slinger, further block the oil leak simultaneously, prevent that the oil slinger from bringing the oil to too high position, improve sealed effect.
Drawings
Fig. 1 is a schematic elevational cross-sectional view of the present utility model.
The character labels in the figure are shown as 1, an inner rotating shaft; 2. an outer rotating shaft; 3. a seal ring; 4. an oil accumulation tank; 5. oil slinger; 6. sealing the comb teeth; 7. an oil baffle gasket.
Detailed Description
In order that those skilled in the art may better understand the technical solutions of the present utility model, the following detailed description of the present utility model with reference to the accompanying drawings is provided for exemplary and explanatory purposes only and should not be construed as limiting the scope of the present utility model.
Example 1:
the inter-shaft sealing structure comprises an outer rotating shaft 2, an inner rotating shaft 1 is rotatably arranged on the outer rotating shaft 2, a sealing ring 3 is arranged between the inner wall of the outer rotating shaft 2 and the outer wall of the inner rotating shaft 1, an oil slinger 5 is arranged at the joint of a port of the outer rotating shaft 2 and the inner rotating shaft 1, and an oil accumulation tank 4 which is used for wrapping the oil slinger 5 and is matched with the inner rotating shaft 1 is arranged on the outer wall of the outer rotating shaft 2; the oil accumulation tank 4 is provided with a hole matched with the bolt, and accumulated oil in the oil accumulation tank 4 can be poured out after the bolt is unscrewed; and a sealing comb tooth 6 is arranged on one side of the outer wall of the inner rotary shaft 1, which is far away from the sealing ring 3, at intervals.
The specific working principle is as follows: when the device is only used, the sealing ring 3 is firstly directly installed on the inner rotary shaft 1, then the oil slinger 5 is inserted, and when the inner rotary shaft 1 rotates in the outer rotary shaft 2, the sealing comb teeth 6 also rotate along with the inner rotary shaft 1 to drive the generated air pressure to match with the sealing ring 3 so as to achieve a better sealing effect; the oil slinger 5 is matched with the internal pressure and the rotation of the inner rotary shaft 1 to bring out the oil at the lower part of the ports, and the oil falls on the shaft at the outer end, so that the lubrication effect is improved, and the redundant oil falls into the oil accumulation tank 4 to be collected. In the process, the device is convenient to install, and the sealing and lubricating effects of the structure are better through the action among the oil slinger 5, the sealing comb 6 and the sealing ring 3.
Example 2:
further optimizing on the basis of the embodiment: the inner wall of the outer rotary shaft 2 is in a taper hole shape. Through the arrangement of the taper hole shape, the device can control the oil drainage direction of the leaked lubricating oil between the two rotating shafts. An oil retaining gasket 7 is arranged on the outer wall of the inner rotary shaft 1 between the oil accumulation box 4 and the oil slinger 5. Through the setting of oil retaining washer 7, make this device can make things convenient for the installation between long-pending oil tank 4 and the oil slinger 5, further block the oil leak simultaneously, prevent that oil slinger 5 from bringing the oil to too high position, improve sealed effect.
