Abstract
The utility model relates to a simple shaft sealing device which comprises a shaft (1), a bearing (2), a sleeve (3), an oil retainer ring (4) and a sealing labyrinth (5). The simple shaft sealing device is characterized in that the sleeve (3), the oil retainer ring (4) and the sealing labyrinth (5) are arranged at the input end or the output end of the shaft; the sealing labyrinth (5) is fixed on a box body by a bolt; the oil retainer ring (4) forms a first sealing defensive line to lubricant oil leaked from the bearing (2); and the sealing labyrinth (5) is a second sealing defensive line.
Description
Technical field
The utility model relates to seal arrangement, is specifically related to a kind of easy shaft seal.
Background technique
In order to improve a stability of rotation, and the noise when reducing the axle rotation, in the cooperation place of axle and bearing lubricant oil need be provided, under most of situation, the lubricant oil of this cooperation place needs constantly imported from oil pump.When axle rotated, particularly during high speed rotating, because the input of axle or output terminal be outside casing, lubricant oil can be through the contacting point of axle with bearing, and perhaps the contacting point of bearing and bearing shell is past excessive.The lubricating oil temperature that overflows is higher, and environment and casing have been caused destruction, and because the overflowing of lubricant oil reduced lubrication effect, gives working life of stable operation and the bearing of axle and has brought no small influence.
Summary of the invention
The purpose of the utility model is to the output of traditional axle or the shortcoming that input end does not have the device of special sealing lubricating oil, and a kind of novel and easy shaft seal that efficient is high is provided.Owing to adopted flinger ring and sealing labyrinth, adopt the axle of this seal arrangement to have the advantage of good sealing effect, high lubricating effect.
The technological scheme of the utility model is:
A kind of easy shaft seal comprises axle 1, bearing 2, sleeve 3, flinger ring 4, sealing labyrinth 5, it is characterized in that sleeve 3, flinger ring 4 and sealing labyrinth 5 are installed in the input or the output terminal of axle; Sealing labyrinth 5 is through being bolted on the casing; 4 pairs of lubricant oil that from bearing 2, leak out of flinger ring form sealing defence line, first road; 5 in labyrinth of sealing is sealing defence line, second road.
The utlity model has following advantage:
1) processing of this seal arrangement is simple and easy, easy for installation.Because the seal arrangement simplicity of design, each constituent element of device can independently be processed, and it is also comparatively convenient to install.
2) good sealing effect.Owing to adopted the twice defence line, sealing effect is relatively good.
Description of drawings
Fig. 1 is a kind of structural representation of easy shaft seal
Among the figure, 1. spool, 2. bearing, 3. sleeve, 4. flinger ring, 5. sealing labyrinth.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1.
A kind of easy shaft seal comprises axle 1, bearing 2, sleeve 3, flinger ring 4, sealing labyrinth 5, it is characterized in that sleeve 3, flinger ring 4 and sealing labyrinth 5 are installed in the input or the output terminal of axle; Sealing labyrinth 5 is through being bolted on the casing; 4 pairs of lubricant oil that from bearing 2, leak out of flinger ring form sealing defence line, first road; 5 in labyrinth of sealing is sealing defence line, second road.
Working procedure
At first bearing 2 is installed on the axle 1, calculates according to the size of reality, the sleeve that processes 3 is in place again, flinger ring 4 is installed in a shaft shoulder place of axle 1, is in place sealing labyrinth 5 at last, and passes through bolt to casing.4 pairs of lubricant oil that from bearing 2, leak out of flinger ring form sealing defence line, first road; 5 in labyrinth of sealing is sealing defence line, second road.
Claims (1)
1. an easy shaft seal comprises axle (1), bearing (2), sleeve (3), flinger ring (4), sealing labyrinth (5), it is characterized in that sleeve (3), flinger ring (4) and sealing labyrinth (5) are installed in the input or the output terminal of axle; Sealing labyrinth (5) is through being bolted on the casing; Flinger ring (4) forms sealing defence line, first road to the lubricant oil that from bearing (2), leaks out; Sealing labyrinth (5) then is sealing defence line, second road.
