Abstract
The utility model relates to a sealing device of a rotating shaft, which comprises a rotating shaft, a shaft block and an end cover, and is characterized in that an oil shedding groove is arranged on the rotating shaft, an oil collecting pan is fixed at the outside of the end cover, an oil collecting chamber is arranged at the bottom of the oil collecting pan, and the oil collecting chamber is communicated with the traverse oil return hole of the shaft block through an oil hole arranged at the bottom of the end cover. In the utility model, the oil shedding groove is arranged on the rotating shaft, thereby the lubricating oil can be prevented from flowing out; and the lubricating oil which is shed out by the oil shedding groove passes through the oil collecting chamber and the oil return hole, and then flows back into a reduction gearbox, thereby, the sealing purpose is realized.
Description
Technical field
The utility model relates to a kind of rotation shaft seal, specifically is used for the seal oil device of speed reducer running shaft.
Background technique
Be used for the especially speed reducer casing of coiling machine of cold rolling transmission device, the seal oil of its high speed shaft or rotary main shaft bearing is an important problem.In actual conditions, because science and technology development, the mill speed of steel rolling equipment is more and more higher, and is also more and more higher as the motion speed of main manufacturing mechanism coiling machine.At present, the seal oil device of high speed shaft or rotary main shaft bearing extensively adopts the rubber oil sea sealing.But because the high speed rotating of shaft, rubber seal is easy to wear away; thereby cause leakage of oil, the envelope of therefore must often changing oil, maintenance cost is than higher; and change oil again when sealing, the coupling on the axle be unloaded or casing be opened, be effort again consuming time like this.
Summary of the invention
The utility model provides a kind of rotation shaft seal simple, economic and reliable of installing at above-mentioned the deficiencies in the prior art.
The technological scheme that provides according to the utility model, a kind of rotation shaft seal, comprise running shaft, bearing support and end cap, feature is: described running shaft is provided with and gets rid of oil groove, the outside of described end cap is fixed with oil drip pan, the bottom of oil drip pan is provided with collection chamber, and collection chamber is connected with cross scavenging hole on the described bearing support by the oilhole of described end cap bottom.
The described oil groove that gets rid of is the profile of tooth groove.
Also be provided with the vertical spill port that is connected with described cross scavenging hole on the described bearing support.
Compared with the prior art the utility model has the following advantages: the utility model running shaft is provided with and gets rid of oil groove, can stop lubricant oil to flow out outward; Got rid of the lubricant oil that oil groove throws away and be back in the deceleration box, thereby reached sealing purpose through collection chamber, spill port; Oil drip pan and end cap are the subdivision structure, and be installing, can dismantling separately when overhauling, time saving and energy saving.

Embodiment
Below in conjunction with the embodiment in the accompanying drawing the utility model is further described.
As Fig. 1～shown in Figure 6, comprise and get rid of oil groove 1, oil drip pan 2, end cap 3, bearing support 4, running shaft 5, high speed shaft 6, oilhole 7, oilhole 8, collection chamber 9, cross scavenging hole 10 and vertical spill port 11 etc.
As shown in Figure 1 and Figure 2, be the structural representation of using speed reducer of the present utility model.All use on the running shaft 5 of speed reducer and the high speed shaft 6 seal arrangement of the present utility model is arranged.The utility model comprises running shaft 5, bearing support 4 and end cap 3.
As Fig. 2, shown in Figure 4, running shaft 5 is provided with and gets rid of oil groove 1, gets rid of oil groove 1 and is the profile of tooth groove, and the 4-5 circle is arranged.The effect of getting rid of oil groove 1 is to stop lubricant oil to flow out outward.
As Fig. 3, Fig. 5 and shown in Figure 6, the outside of end cap 3 is welded with oil drip pan 2, and the bottom of oil drip pan 2 is welded with collection chamber 9.Collection chamber 9 is a box body, and its top communicates with the oilhole 7 of oil drip pan 2 bottoms.Collection chamber 9 is connected with cross scavenging hole 10 on the bearing support 4 by the oilhole 8 of end cap 3 bottoms.
Oil drip pan 2 and end cap 3 are the subdivision structure.Installing, need not devaning, unload coupling during maintenance, can dismantle this end cap 3 separately, promptly save time, laborsaving again.
As shown in Figure 3, also be provided with the vertical spill port 11 that is connected with cross scavenging hole 10 on the bearing support 4.Vertical spill port 11 is back to the lubricant oil in the bearing in the casing.
Using process of the present utility model: the high speed shaft 6 of coiling machine speed reducer goes out axle head and running shaft 5 two ends because high speed rotating needs the thin oil lubricant bearing.Some casing that splashes back of lubricant oil, some rotary centrifugal force through axle gets rid of toward going out axle direction, get rid of oil groove 1 through going out on the axle direction, oil can be splashed on the oil drip pan 2 of end cap 3 external weldings, deposit to then in the bottom collection chamber 9 of oil drip pan 2, be back in the deceleration box through oilhole 8 on the end cap 3 and the cross scavenging hole 10 on the housing bearing seat 4 again, thereby reach sealing purpose.
