Abstract
The invention discloses a throttler which comprises a shell and a throttle body, wherein the throttle body is arranged on one end of the shell, the inner side of the upper end of the throttle body is provided with a thread, the middle end of the throttle body is a cylinder the both sides of which are provided with through-flow holes, the outside diameter of the middle end of the throttle body is less than that of the upper end of the throttle body, the lower end of the throttle body is a solid cylinder, an oil collector chamber is arranged below the lower end of the throttle body, and the middle end of the shell is provided with a ring cylindrical projection; and the outside surface of the upper end of the throttle body is provided with a thread, the outside diameter of the lower end of the throttle body is greater than that of the middle end of the throttle body, and the outside surface of the lower end of the throttle body is provided with a spiral oil supply tank. According to the invention, the lower end of the throttle body is provided with the spiral oil supply tank and is consistent with the ring cylindrical projection, the upper end of the throttle body and the shell are connected by the thread, and the flow of oil can be adjusted according to specific demands.
Description
Technical field
The present invention relates to a kind of flow controller.
Background technique
Existing throttle style mainly contains film feedback-throttling, guiding valve feedback throttle and internal surface feedback throttle etc.The defective of film feedback-throttling is: size is large, can only be placed on bearing support, thereby the feedback oil circuit is longer, affects the raising of dynamic stiffness, and its parameter may not cause the machine can't normal operation at that time.The defective of internal surface feedback throttle is: need to take the area of oil pocket internal surface, it is large that the bearing axial dimension becomes, and for the little bearing of interior hole dimension, the internal surface throttling is difficult to processing, and influential to the high speed performance of main shaft.In addition, similar these flow controller, its throttling performance is fixed after selected, can not regulator throttling performance when working.
Summary of the invention
The present invention is directed to the deficiencies in the prior art part, a kind of new flow controller is provided.
the scheme that the present invention solves the prior art problem is: a kind of flow controller, comprise housing, throttling bodies is arranged on an end throttling bodies of housing, the inboard of throttling bodies upper end is provided with screw thread, the throttling bodies middle-end is the cylindrical body that both sides are provided with through flow hole, and the external diameter of throttling bodies middle-end is less than throttling bodies upper end external diameter, and the throttling bodies lower end is solid cylinder, the below of throttling bodies lower end is the oil trap chamber, and the housing middle-end is provided with the ring cylindrical bump, throttling bodies upper end outer surface is provided with screw thread, the external diameter of throttling bodies lower end is greater than the external diameter of throttling bodies middle-end, throttling bodies lower end outer surface is provided with the spiral oil supply, the upper end of throttling bodies and the inside of middle-end are provided with the hole, the height of ring cylindrical bump is identical with the height of throttling bodies lower end, the upper and lower surface of ring cylindrical bump is equal with the upper and lower surface of throttling bodies lower end height, there is a toroidal cavity intersection of ring cylindrical bump and throttling bodies lower end, housing upper end internal surface is provided with screw thread, the screw thread of the upper end outer surface of throttling bodies matches with the screw thread of shell inner surface, form thread seal.
Compared with prior art, in the present invention, the throttling bodies lower end is provided with the spiral oil supply, and the lower end is consistent with the ring cylindrical bump, adopts between throttling bodies upper end and housing to be threaded, and can regulate oily flow according to concrete conditions of demand.
