Abstract
The invention provides a ball friction oil-feeding structure for a vacuum rotary seal pump. The structure comprises a main shaft and a supporting mating member, wherein the supporting mating member is provided with a shaft aperture, the main shaft is installed in the shaft aperture of the supporting mating member, an oil-feeding hole perpendicular to the main shaft is arranged in the sidewall of the supporting mating member, a screw thread is processed on the inner wall of the oil-feeding hole, a ball pushing block is installed in the oil-feeding hole, a ball is arranged in the oil-feeding hole at the inner side of the ball pushing block, a mating surface of the ball pushing block and the ball is semicircular, a layer of porous polyester oil absorption pads are arranged on the interior surface of the ball pushing block, and at least two through oil absorption holes are arranged on the ball pushing block. The ball friction oil-feeding structure for the vacuum rotary seal pump is simply designed and has a good usage effect.
Description
Technical field
The present invention relates to a kind of vacuum pump, especially a kind of ball friction oil charging structure 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 vacuum rotatory sealing pump ball friction oil charging structure.
The objective of the invention is to be achieved through the following technical solutions:
Vacuum rotatory sealing pump ball friction oil charging structure, comprise main shaft and support counterpart, described support counterpart is provided with axis hole, described main shaft is installed in the axis hole that supports counterpart, sidewall at described support counterpart is provided with the oil inlet hole vertical with described main shaft, machining screw on the inwall of oil inlet hole, the ball pushing block is installed in oil inlet hole, in the inboard oil inlet hole of described ball pushing block ball is installed, the fitting surface of described ball pushing block and ball is semicircle, internal surface at described ball pushing block is provided with one deck porous polyester oil sucting pad, is provided with the oil-sucking hole of at least two perforations at described ball pushing block; Corresponding described ball, be provided with the incomplete boss of a circle at described main shaft, and at the outside of described incomplete boss main shaft axle sleeve is installed, described axle sleeve is positioned at the inside of described support counterpart, described incomplete boss is the boss with at least one breach, and the internal surface of described incomplete boss outer surface and described support counterpart keeps certain space.
Described oil inlet hole is made as three, is distributed on the outer shroud of described boss.
Can by adjusting the position of ball pushing block in oil inlet hole, adjust the oil inlet quantity of described ball; Described incomplete boss cooperates with ball, the lubricant oil that ball will be adsorbed on the described porous polyester oil sucting pad in the process of rolling is transferred on the described incomplete boss, in the process of active rotation, the breach that described ball and incomplete boss are hindered is close, the no longer rolling friction of ball this moment, but being in the state that stops, will no longer carrying out fuel feeding this moment.
Vacuum rotatory sealing pump ball friction oil charging structure of the present invention, the total simplicity of design, using effect is good.
