Abstract
The invention discloses an oil filling device of a vacuum rotating seal pump. The oil filling device of the vacuum rotating seal pump comprises a rotating main shaft and a shaft sleeve, wherein the surface of the rotating main shaft is provided with an annular boss; a sleeve sealing piece is arranged outside the boss; the sleeve sealing piece is positioned between the rotating main shaft and the shaft sleeve; a partial gap is formed in the boss; an oil inlet corresponding to the boss is formed in the shaft sleeve; a ball which is supported by a spring is arranged on the oil inlet; the diameter of the ball is the same as that of the oil inlet; an inclined oil inlet groove is formed in the oil inlet at the lower part of the ball; when the partial gap of the boss is contacted with the ball, the ball is jacked towards the rotating main shaft by the action of the spring, the oil inlet groove of the oil inlet can be communicated with the partial gap of the boss, and lubricating oil is filled in the partial gap of the boss under the action of the pressure of oil in the oil inlet; and when the rotating main shaft rotates by a circle, a trace of lubricating oil enters between the rotating main shaft and the shaft sleeve, and then the aims of automatic oil filling and controllable oil filling amount can be realized.
Description
Technical field
The present invention relates to a kind of vacuum pump, especially a kind of oiling device that is applied to vacuum rotatory sealing pump.
Background technique
Vacuum pump is in the process of oiling, because what adopt at rotatable parts all is rotary seal, and the problem that causes sealing to descend when causing oiling easily like this.For the problems referred to above, have the people to apply for that in 2009 the patent No. is 200920048234 the lubricating cup that is used for vacuum rotatory sealing pump, but this patent still can not well solve the rotary seal problem in the oiling process.
Summary of the invention
Based on the problems referred to above, the invention provides a kind of oiling device of vacuum rotatory sealing pump.
The objective of the invention is to be achieved through the following technical solutions:
The oiling device of vacuum rotatory sealing pump, comprise rotary main shaft and axle sleeve, be provided with the boss of ring-type on the surface of rotary main shaft, the outside of described boss is provided with sleeve seal, described sleeve seal is between described rotary main shaft and axle sleeve, described boss is provided with the part breach, corresponding described boss has oil inlet hole at described axle sleeve, spring-supported ball is installed in oil inlet hole, the diameter of described ball is identical with the diameter of described oil inlet hole, and the oil inlet hole in the ball bottom has the oil-feed tank of inclination.
Described axle sleeve and external fixation device are fixed, and itself does not rotate axle sleeve.
When the part breach of boss contacts with ball, by the elastic force effect ball is pushed up to rotary main shaft, at this moment the oil-feed tank of oil inlet hole will communicate with the part breach of boss, by the oil pressure effect in the oil inlet hole, lubricant oil is injected in the part breach of described boss, when rotary main shaft whenever revolves when turning around, enter between rotary main shaft and the axle sleeve with regard to the lubricant oil that has trace, just reached the controlled purpose of automatic oiling and volume read-out.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the cross-sectional structure figure of the oiling device of the described vacuum rotatory sealing pump of the embodiment of the invention.
Fig. 2 is the vertical section structure figure of the oiling device of the described vacuum rotatory sealing pump of the embodiment of the invention.
Fig. 3 is the partial enlarged drawing among Fig. 2.
Embodiment
As Figure 1-3, the oiling device of the described vacuum rotatory sealing pump of the embodiment of the invention, comprise rotary main shaft 1 and axle sleeve 2, be provided with the boss 3 of ring-type on the surface of rotary main shaft 1, the outside of described boss 3 is provided with sleeve seal 4, described sleeve seal 4 is between described rotary main shaft 1 and axle sleeve 2, described boss 3 is provided with part breach 5, corresponding described boss 3 has oil inlet hole 6 at described axle sleeve 2, the ball 8 that spring 7 supports is installed in oil inlet hole 6, the diameter of described ball 8 is identical with the diameter of described oil inlet hole 6, and the oil inlet hole in ball 8 bottoms has the oil-feed tank 9 of inclination.
Described axle sleeve 2 is fixed with external fixation device, and axle sleeve 2 itself does not rotate.
When the part breach of boss contacts with ball, by the elastic force effect ball is pushed up to rotary main shaft, at this moment the oil-feed tank of oil inlet hole will communicate with the part breach of boss, by the oil pressure effect in the oil inlet hole, lubricant oil is injected in the part breach of described boss, when rotary main shaft whenever revolves when turning around, enter between rotary main shaft and the axle sleeve with regard to the lubricant oil that has trace, just reached the controlled purpose of automatic oiling and volume read-out.
Claims (2)
1. the oiling device of a vacuum rotatory sealing pump, comprise rotary main shaft and axle sleeve, it is characterized in that, be provided with the boss of ring-type on the surface of rotary main shaft, the outside of described boss is provided with sleeve seal, described sleeve seal is between described rotary main shaft and axle sleeve, described boss is provided with the part breach, corresponding described boss has oil inlet hole at described axle sleeve, spring-supported ball is installed in oil inlet hole, the diameter of described ball is identical with the diameter of described oil inlet hole, and the oil inlet hole in the ball bottom has the oil-feed tank of inclination.
2. according to the oiling device of claim 1 described vacuum rotatory sealing pump, it is characterized in that described axle sleeve and external fixation device are fixed, itself does not rotate axle sleeve.
