Description
Technical field
The present invention relates to a kind of processing method of distribution oil ring, especially relate to a kind of processing method of split-type shaft system distribution oil ring.
Background technology
Oil distributor is widely used on the various mechanical parts as being the requisite device of fuel feeding to mechanical axis.No matter past be the distribution oil ring of oil distributor or the low pressure draining ring on its both sides is monoblock type.This distribution oil ring ring body is sleeved on the oil distribution shaft, and displacement enters in the axle by oilhole and oil groove on the ring with pressure oil.In tuning for Controllable Pitch Propeller when work,, oil distribution shaft rotates at a high speed, and distribution oil ring does not rotate, hydraulic oil by distribution oil ring with hydraulic oil distribution in two chambeies of displacement oil cylinder, the displacement oil cylinder is moved back and forth.
Low pressure draining ring is installed in the both sides of distribution oil ring, its effect is the hydraulic oil that distribution oil ring leaks to be collected flow back to the draining case, distribution oil ring on the axle and low pressure draining link have been economized the space, but the dismounting maintenance is difficulty relatively, if distribution oil ring or low pressure draining ring or seal wherein break down, must take shaft coupling apart, remove oil distribution shaft, reserve certain withdrawal space, distribution oil ring or low pressure draining ring could be pulled down from oil distribution shaft.
At the problems referred to above, can adopt dissection type oil distributor structure, just make distribution oil ring and low pressure draining ring all make two semicircle bearing shell shapes, and its faying face is provided with clamping screw and alignment pin, the oil distributor structure that formation is convenient to take apart.But process this dissection type distribution oil ring respectively according to conventional method processing, the processing technology complexity, the axiality of its endoporus and circularity are difficult to meet the requirements, difficult quality guarantee.And the babbit layer on can't the spun casting endoporus, even with babbitting again after two circular bearing shells locking in the distribution oil ring, then can cause the phenomenon that babbit layer is difficult for cutting apart in the endoporus, or be difficult to realize split type structure, or increase the difficulty that distribution oil ring is processed, cause the reduction of its endoporus crudy.
Summary of the invention
The objective of the invention is at existing processing method processing technology complexity, quality is low, and the defective of babbit on the endoporus of can't casting proposes a kind of processing method of split-type shaft system distribution oil ring.
The present invention is mainly solved by following technical proposals:
The processing method of split-type shaft system distribution oil ring comprises the steps:
A. process the blank of semi-ring and following semi-ring, the Hough face on the first roughing blank with the synthetic annulus of the blank of last semi-ring and following semi-ring, in its Hough face outer wall spot welding, makes it constitute a domain, then roughing cylindrical, end face, endoporus and babbit groove;
B. joining auger shell keyhole and corresponding hole internal tapping on following semi-ring on the side of semi-ring on the domain after the roughing, on the opposite side of semi-ring on the domain, join and bore and the articulation dowel hole;
C. take the solder joint on the domain apart, between the Hough face of last semi-ring and following semi-ring, fill up metallic plate, and metallic plate is stretched out to the endoporus center, its length of stretching out should be more than or equal to the thickness of institute's babbitting layer thereafter, then with bolt and sealed semi-ring and the following semi-ring gone up of alignment pin;
D. adopt the spun casting mode by on babbitting layer in the endoporus that constitutes of semi-ring and following semi-ring;
E. pull down bolt and alignment pin, separately go up semi-ring and following semi-ring, remove metallic plate, Hough face in the fine finishining on semi-ring and the following semi-ring, and, on last semi-ring, bore oilhole and tapping, fine finishining endoporus and oil groove once more with bolt and sealed semi-ring and the following semi-ring gone up of alignment pin.
In the processing method of above-mentioned split-type shaft system distribution oil ring, the thickness of metallic plate described in the step C is 0.1～0.5 millimeter, and corresponding bolt hole and dowel hole have hole or groove on the metallic plate.
In the processing method of above-mentioned split-type shaft system distribution oil ring, described metallic plate is copper coin or steel plate.
Therefore, the present invention has following advantage and beneficial effect:
1. realize the monoblock type processing of dissection type distribution oil ring, particularly passed through metallic plate, integral cast babbit again on Hough face pad after the roughing.Metallic plate is easier to separate with babbit layer, can prevent that two babbit layer adhesions on the semicircle bearing shell are integral, and guarantee that its babbit layer and base material are connected firmly, and has solved the casting problem of babbit on two semi-rings.
2. processing technology is simple, utilize spot welding in the roughing, thereafter utilize bolt on the distribution oil ring and alignment pin two semi-rings that are locked, the frock device is few, and can guarantee the machining accuracy of distribution oil ring endoporus, Pasteur's alloy layer thickness uniformity in the endoporus, overcome the monolateral phenomenon of babbit layer gage distortion after the fine finishining, the yield rate of distribution oil ring is higher, and quality is good, low cost of manufacture, long service life.
3, the scope of application is wider.Structural requirement to oil distribution shaft reduces, as shown in Figure 1.The dissection type distribution oil ring can not taken apart under the situation about connecting of oil distribution shaft and adjacent shaft, separate from the outer surface of axle, so oil distribution shaft and adjacent shaft to connect form unfettered, can be for the folder clam coupling, also can be present widely used fluid coupling (hydraulic-pressure sleeve and hydraulic pressure flange all can), can also be that the high mounting flange of economy connects.
4, installation and removal are convenient, are convenient to maintenance, change.The monoblock type distribution oil ring must be thrown off oil distribution shaft when maintenance or replacing, and leaves certain end play, makes distribution oil ring take off or load onto from axle, and workload is very big, and the time of maintenance, replacing is long.The dissection type distribution oil ring does not need oil distribution shaft to move axially can to dismantle, so the connection that does not need to take apart oil distribution shaft and adjacent shaft during maintenance need not disconnect the connection in the axle yet, the time of having saved the distribution oil ring maintenance greatly or having changed, has alleviated workload.
