Abstract
The utility model relates to a seal and dustproof structure for an AY multistage centrifugation oil pump bearing body. A bearing body is provided with a bearing end cover; and the inner side of the bearing end cover is equipped with a thrust adjusting sleeve. The dustproof structure is characterized in that an O-shaped ring groove is arranged on the inner side of the bearing end cover; an O-shaped seal ring is disposed in the O-shaped ring groove; the O-shaped seal ring is arranged between the bearing end cover and the thrust adjusting sleeve; and the thrust adjusting sleeve is further provided with an oil resistant rubber dustproof ring. Compared with an original structure, the seal and dustproof structure for the AY multistage centrifugation oil pump bearing body, more safety and reliability are provided; the seal and dustproof structure has beautiful contour and simple installation; by the use of the seal and dustproof structure, mechanical machining difficulty is lowered, so is assembling difficulty; and construction time is reduced and production cost is lowered.
Description
Technical field
The utility model relates to multistage centrifugal oil pump bearing support sealing and dustproof part design method, particularly a kind of AY multistage centrifugal oil pump bearing support sealed dustproof structure.
Background technique
Common AY type multistage centrifugal oil pump bearing (ball) cover place (as Fig. 1), what adopt is the labyrinth seal of rectangle sawtooth, and bearing (ball) cover 2 is fixed by bolts on bearing support 1, separately has dust cover 3 in its side, with Cock screw 4, be fixed in thrust adjusting sleeve 5, with this sealing and dustproof, leakproof wet goods.Precessing saw tooth-shape labyrinth, processing is comparatively complicated, and while taking a lot of work, dustproof cover structure is also comparatively complicated, all complicated and time-consuming when overall structure causes machining and installs.
Model utility content
The purpose of this utility model is to provide a kind of processing easy-to-install AY multistage centrifugal oil pump bearing support sealed dustproof structure.
To achieve these goals, the technical solution of the utility model is as follows: a kind of AY multistage centrifugal oil pump bearing support sealed dustproof structure, described bearing support is provided with bearing (ball) cover, the inner side of described bearing (ball) cover is provided with a thrust adjusting sleeve, it is characterized in that establishing O type ring recess inside bearing (ball) cover, in described O type ring recess, be provided with 0 RunddichtringO, described 0 RunddichtringO is arranged between bearing (ball) cover and thrust adjusting sleeve, in described thrust adjusting sleeve, is also provided with oil resistant rubber dust ring.According to preferred embodiment of the present utility model, described bearing (ball) cover endoporus place thickness is 18 ~ 22 millimeters, and the thickness of dust ring is 4 ~ 6 millimeters, is highly 8 ~ 12 millimeters, enables to play better the effect that stops the impurity such as dust granule.
The utility model is the improvement for AY multistage centrifugal oil pump bearing support sealing and dustproof modular construction.Bearing (ball) cover casting dimension is suitably adjusted to thickening, and O type ring recess is opened in inner side, uses oil resistant, resistant to elevated temperatures fluororubber O-type seal ring, guarantees suitable decrement, can play preferably the effect of sealing.Meanwhile, can consider to add an oil resistant rubber dust ring in thrust adjusting sleeve, play the effect that stops the impurity such as dust granule.The utility model structure is more safe and reliable compared with original structure, beautiful shape, and simple installation, has reduced the difficulty of machining, and the difficulty while simultaneously having reduced assembling, has reduced man-hour, has saved production cost.
