Abstract

The invention relates to a sealing device of a rotating shaft, comprising the rotating shaft, a bearing seat and an end cover. The sealing device is characterized in that the rotating shaft is provided with an oil throwing groove; the outer side of the end cover is fixed with an oil receiving tray, the bottom of which is provided with an oil collecting cavity; and the oil collecting cavity is communicated with a transverse oil return hole arranged on the bearing seat through an oil hole at the bottom of the end cover. As the oil throwing groove is arranged on the rotating shaft, lubricating oil can be prevented from flowing outside; and the lubricating oil thrown out by the oil throwing groove flows into a speed reducing box through the oil collecting cavity and the oil return hole, thus the aim of sealing can be achieved.

Description

The rotation shaft seal
Technical field
The present invention relates to a kind of rotation shaft seal, specifically be 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 present invention is directed to above-mentioned the deficiencies in the prior art, a kind of rotation shaft seal simple, economic and reliable of installing is provided.
According to technological scheme provided by the invention, 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 present invention has the following advantages: the present invention's 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
The present invention is further illustrated below in conjunction with the embodiment in the accompanying drawing.
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 invention.All use on the running shaft 5 of speed reducer and the high speed shaft 6 seal arrangement of the present invention is arranged.The present invention includes 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 invention: 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.
