Description
Technical field
The present invention relates to a kind of flow controller.
Background technology
Existing throttle style mainly has film feedback-throttling, guiding valve feedback throttle and inner surface feedback throttle etc..Film
The defects of feedback throttle, is：Size is big, can only be placed on bearing body, thus feedback oil circuit is longer, influences the raising of dynamic stiffness,
And its parameter may cause machine can not normal operation at that time.The defects of inner surface feedback throttle, is：Need to take oil pocket
The area of inner surface, bearing axially become large-sized, and for the small bearing of hole size, inner surface throttling is difficult processing, and also
Have an impact to the high speed performance of main shaft.In addition, these similar flow controller, its performance that throttles is fixed after selected, is being worked
Shi Buneng adjusters throttling performance.
The content of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of flow controller, the body lower end that throttled in the present invention is set
There is spiral oil supply tank, lower end is consistent with ring cylindrical bump, and throttling to use between body upper end and housing is threadedly coupled, Ke Yigen
According to the flow of specific conditions of demand regulation oil.
In order to reach foregoing invention purpose, the technical solution adopted by the present invention is：
A kind of flow controller, including：Housing, the housing are provided with throttling body upper end, and the inner side of the throttling body upper end is provided with spiral shell
Line, the throttling body middle-end are the cylinders that both sides are provided with through flow hole, and the external diameter of the throttling body middle-end is less than throttling body upper end
External diameter, the throttling body lower end is solid cylinder, is collection chamber below the throttling body lower end, the housing middle-end is provided with
Ring cylindrical bump, the throttling body upper end outer surface are provided with screw thread, and the external diameter of the throttling body lower end is more than throttling body middle-end
External diameter, it is described throttling body lower end outer surface be provided with spiral oil supply tank.
Further, the upper end of the throttling body and the inside of middle-end are provided with hole.
Further, the height of the ring cylindrical bump is identical with the height of throttling body lower end.
Further, the upper and lower surface of the ring cylindrical bump is equal with the upper and lower surface of throttling body lower end height.
Further, there is a toroidal cavity ring cylindrical bump and the intersection of throttling body lower end.
Further, housing upper end inner surface is provided with screw thread.
Beneficial effects of the present invention are：
Throttling body lower end is provided with spiral oil supply tank in the present invention, and lower end is consistent with ring cylindrical bump, and throttle body upper end and shell
Using threaded connection between body, oily flow can be adjusted according to specific conditions of demand.
