Abstract
An oil device of a vacuum rotating sealed pump comprises a rotating main shaft and a shaft sleeve. An annular boss is arranged on the surface of the rotating main shaft, a sleeve sealing piece is arranged outside the boss, and the sleeve sealing piece is arranged between the rotating main shaft and the shaft sleeve. The boss is provided with a partial notch, and an oil inlet hole is formed in the shaft sleeve corresponding to the boss. A roll ball which is supported by a spring is mounted inside the oil inlet hole, the diameter of the roll ball and the diameter of the oil inlet hole are the same, and an oblique oil inlet groove is formed in an oil inlet hole on the lower portion of the roll ball. When the partial notch of the boss contacts with the roll ball, the roll ball is jacked to the rotating main shaft through elastic force, and at the time, the oil inlet groove of the oil inlet hole can be communicated with the partial notch of the boss, and lubricating oil is injected into the partial notch of the boss through the oil pressure effect of the oil inlet hole. Every time when the rotating main shaft rotates a circle, a trace amount of the lubricating oil can enter between the rotating main shaft and the shaft sleeve, and the purposes that oil injecting is automatic and the amount of injecting oil can be controlled are achieved.
Description
Technical field
The utility model 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.
The model utility content
Based on the problems referred to above, the utility model provides a kind of oiling device of vacuum rotatory sealing pump.
The purpose of this utility model 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 utility model 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 utility model embodiment.
Fig. 2 is the vertical section structure figure of the oiling device of the described vacuum rotatory sealing pump of the utility model embodiment.
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 utility model embodiment, 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.
