Abstract
The utility model provides a non-contact sealing device. The shaft of the sealing device is provided with a bearing; a box body is arranged outside the bearing and provided with an oil inlet hole; the oil inlet hole is communicated with an oil cavity; the box body is internally provided with two oil returning chutes, one oil returning chute is positioned lower than the other oil returning chute, one side of the oil cavity is provided with the bearing, and the other side thereof is provided with an oil retaining disc; the other side of the oil retaining disc is provided with an oil returning cavity; an oil slinger is arranged above the oil returning cavity; the oil slinger is provided with a felt collar; a through cover is arranged outside the oil slinger; the through cover is internally provided with a pin used for positioning and aligning the through cover and the oil retaining disc; and the through cover is fixed on the box body. The sealing device is not contacted with the shaft so as to prevent abrasion and heating, and applicable to transmission devices which runs at high speed, and has good sealing performance and reasonable design, easily installation and disassembly, convenient replacement and maintenance.
Description
Technical field
The utility model relates to the shaft sealing field, specially refers to untouchable seal arrangement.
Background technique
In all kinds of engineering machinery the sealing of transmission shaft be one very general but be a very main problem.The oil sealing form is all adopted in the sealing of each transmission shaft and output shaft at present, the single oil sealing of the employing that has, and the employing dual-oil seal that has, no matter adopt which kind of oil sealing mode, all can only be applicable to driving mechanism low, the middling speed running, but also have the seal ring heating, serious wear to axle, the easily aging and damage of oil sealing, and replacing is difficult, and the generation that produces phenomenons such as leakage of oil, oil impregnate.And the technological design of oil sealing and limited air-proof condition makes for the driving mechanism of running highly, can't reach the requirement of sealing.
Summary of the invention
The purpose of this utility model is to provide a kind of untouchable seal arrangement that does not have oil sealing.
For achieving the above object, the technical solution of the utility model is:
On the axle in the untouchable seal arrangement bearing is housed, there is casing outside at bearing, oil inlet hole is arranged on the casing, have oil-return groove 12 and oil-return groove 13 in the casing, and the position of oil-return groove 13 is lower than oil-return groove 12, oil inlet hole is connected with oil pocket, one side of oil pocket is a bearing, and opposite side has oil baffle disc, and the another side of oil baffle disc has oil back chamber, disc is equipped with in the top of oil back chamber, disc is contained on the axle, and felt collar is housed on the disc, and logical lid is equipped with in the outside of disc, Tong Gainei is equipped with the pin that is used for logical lid and oil baffle disc location, and logical lid is fixed on the casing.
Good effect of the present utility model is:
1, seal arrangement does not touch with being coupling, and has prevented the generation of wearing and tearing and heating phenomenon;
2, seal arrangement is not only applicable to transmission device low, the middling speed running, is applicable to the transmission device that runs up simultaneously yet;
3, good seal performance has improved the reliability of seepage-proof oil;
4, reasonable in design, easily installation and removal, replacing, easy to maintenance.

Fig. 1, untouchable sealing device structure sectional view;
Fig. 2, body partial side view.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing 1-2.
With reference to Fig. 1, extreme pressure lubricant is by oil pump oil inlet hole 4, enter in the oil pocket 11 through oil inlet hole 4 again, under the effect of oil baffle disc 10, the bearing 2 that oil pocket 11 another sides are contained on the axle 1 is lubricated, when the lubricant oil in the oil pocket 11 reaches the height of oil-return groove 12, lubricant oil is then let out back in the casing 3 by oil-return groove 12 overflows of opening on casing 3, in this process, the seldom lubricant oil of part infiltration is arranged, under the effect of disc 8, the lubricant oil of all infiltrations is got rid of Huis oil pocket 9, (see figure 2) when the lubricant oil in the oil back chamber 9 reaches the height of oil-return groove 13, lubricant oil then overflow back in the casing 3 by the oil-return groove of opening on casing 3 and the position is lower than oil-return groove 12 13.Wherein pin 5 be used for logical cover 6 and the location of oil baffle disc 10 align, and oil baffle disc 10 is fixed on logical the lid on 6, the felt collar on the disc 8 is used for resisting and leads to the intrusion of covering 6 outside air dust.After the lubricant oil in the casing 3 is filled, can it be pumped casing 3 by oil hydraulic pump, concentrate to use or add to pump into again and participate in lubricated stroke in the oil inlet hole 4.
