Method for processing split-type shaft system distribution oil ring

Abstract

A split shafting oil distribution ring processing method comprises the following steps that half surfaces 2 of the roughcast is milled and an upper half ring 1 and lower half ring 7 are combined into a ring; spot welding is implemented on the external wall and then rough processing is carried out on an external circle, an end face, an internal hole and a Babbitt alloy groove; the integral ring is equipped with a bolt hole 4 and a locating pin hole 5; the welding spots on the integral ring is dismantled and a metal plate 3 is underlaid between half surfaces 2; the metal plate is penetrated out to the internal hole center; the upper half ring 1 and lower half ring 7 are locked and a Babbitt alloy layer 6 is cast; the metal plate 3 and an oil hole 8, the finished internal hole and an oil sink are dismantled. The present invention solves the casting problem of Babbitt alloy on the two half rings and realizes the integral processing of split oil distribution ring; the processing technique is simple and the frock parts are little; in addition, the internal hole processing precision can be ensured; the thickness of the Babbitt alloy layer of the internal hole is even and consistent which overcomes the singe-side phenomenon; the oil distribution ring yield and quality are high; the production cost is low and service life is long.

Description

technical field [0001] The invention relates to a processing method for an oil distribution ring, in particular to a processing method for a split shaft oil distribution ring. Background technique [0002] As an essential device for supplying oil to the mechanical shafting, the oil distributor is widely used in various mechanical parts. In the past, both the oil distribution ring of the oil distributor and the low-pressure oil drain rings on both sides were integral. The ring body of this oil distribution ring is set on the oil distribution shaft, and the pressure oil for variable pitch enters the shaft through the oil holes and oil grooves on the ring. When the pitch control propeller is working, the oil distribution shaft rotates at high speed, the oil distribution ring does not rotate, and the hydraulic oil is distributed to the two chambers of the variable pitch cylinder through the oil distribution ring, so that the pitch variable cylinder reciprocates. [0003] The l...

Problems solved by technology

[0005] The purpose of the present invention is to propose a processing method for the split shaft oil distribution ring in view of the defects of the existing processing method that the processing technology is complex, the quality is low, and the Babbitt alloy on the inner hole cannot be casted.
