Abstract
An oil inlet structure of a vacuum rotating sealed pump rotating main shaft comprises a rotating main shaft and a main shaft supporting piece. The rotating main shaft is arranged inside a shaft hole of the main shaft supporting piece, and a circle of boss is arranged on the rotating main shaft. The rotating main shaft outside the bosses is connected with a shaft sleeve in a sleeved mode, and the shaft sleeve is placed inside the main shaft supporting piece. A certain distance is reserved between the outside of the boss and the inner wall of the main shaft supporting piece so that a gap is formed between the boss and the main shaft supporting piece. An oil injecting hole is formed in the side wall of the main shaft supporting piece, corresponding to the boss. An oil injecting connector is arranged inside the oil injecting hole in a sealing mode, a roll ball which is supported by a spring is arranged at the top end of the oil injecting connector, and the roll ball abuts against the boss. When the rotating main shaft drives the boss to rotate, rolling friction is achieved between the boss and the roll ball, so that lubricating oil inside the oil injecting connector can be conveyed to the boss little by little by the roll ball, and the purpose of oil injecting is achieved.
Description
Technical field
The utility model relates to a kind of vacuum pump, especially a kind of vacuum rotatory sealing pump rotary main shaft oil charging structure that is applied to.
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 vacuum rotatory sealing pump rotary main shaft oil charging structure.
The purpose of this utility model is to be achieved through the following technical solutions:
Vacuum rotatory sealing pump rotary main shaft oil charging structure, comprise rotary main shaft and main shaft support part, described rotary main shaft is installed in the axis hole of main shaft support part, be provided with a circle boss at rotary main shaft, rotary main shaft in described boss outside is socketed with axle sleeve, described axle sleeve is positioned at the inside of described main shaft support part, keep certain distance between the inwall of the outside of described boss and main shaft support part, make between the inwall of boss and main shaft support part and form the slit, corresponding described boss has oil hole at the sidewall of described main shaft support part, be sealed and installed with the oiling joint in the described oil hole, be provided with spring-supported ball on the top of described oiling joint, described ball withstands on the described boss.
When rotary main shaft drives the boss rotation, carry out rolling friction between boss and the ball, ball just can be transferred on the described boss the lubricant oil of oiling joint inside is piecemeal like this, reached the purpose of oiling, and all be under airtight condition, to carry out in the whole oiling process, and do not affect the rotation of rotary main shaft, so can reach good oiling effect, simple in structure, easy to install and use.
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 described vacuum rotatory sealing pump rotary main shaft of the utility model embodiment oil charging structure.
Fig. 2 is the vertical section structure figure of the described vacuum rotatory sealing pump rotary main shaft of the utility model embodiment oil charging structure.
Fig. 3 is the partial enlarged drawing among Fig. 2.
Embodiment
As Figure 1-3, the described vacuum rotatory sealing pump rotary main shaft of the utility model embodiment oil charging structure, comprise rotary main shaft 1 and main shaft support part 2, described rotary main shaft 1 is installed in the axis hole of main shaft support part 2, be provided with a circle boss 3 at rotary main shaft 1, rotary main shaft 1 in described boss 3 outsides is socketed with axle sleeve 4, described axle sleeve 4 is positioned at the inside of described main shaft support part 2, keep certain distance between the inwall of the outside of described boss 3 and main shaft support part 2, make between the inwall of boss 3 and main shaft support part 2 and form the slit, corresponding described boss 3 has oil hole 5 at the sidewall of described main shaft support part 2, be sealed and installed with oiling joint 6 in the described oil hole 5, be provided with the ball 8 that spring 7 supports on the top of described oiling joint 6, described ball 8 withstands on the described boss 3.
When rotary main shaft drives the boss rotation, carry out rolling friction between boss and the ball, ball just can be transferred on the described boss the lubricant oil of oiling joint inside is piecemeal like this, reached the purpose of oiling, and all be under airtight condition, to carry out in the whole oiling process, and do not affect the rotation of rotary main shaft, so can reach good oiling effect, simple in structure, easy to install and use.
