Embodiment
Fig. 1 is the basic structure form of piston oblique wave oil distributing ring 1 of the present utility model, and it is by oblique wave grommet 1-1, interior scraper ring 1-2, and outer scraper ring 1-3 forms.Interior scraper ring 1-2 is flat mouth ring, and outer scraper ring 1-3 presses cylinder diameter size, is that flat mouth ring or radial ladder take choma.Grommet 1-1 is a connected head-to-tail ramp waveform annulus by Spring Steel Band rolling, and its unfolded drawing as shown in Figure 2.Fig. 3 is the plan view of Fig. 2.Oblique wave generally becomes 20-45 ° of angle with the bus of cylinder 2.The inner side upper and lower end of grommet 1-1 has the inner stopper formed by the bead 1-1-1 of recessed ripple 1-1-4; The intermediate portion of its convex ripple 1-1-3 has oiling aperture 1-1-2, and the outer cylinder surface of convex ripple 1-1-3 is coated with one deck soft metal or mild alloy.When detecting in reference gauge oblique wave oil distributing ring 1 being placed in corresponding cylinder diameter, inside and outside scraper ring 1-2 and 1-3 is bearing on the inner stopper of bead 1-1-1 formation with inner headed face up and down, and periphery is then bearing on the inwall of reference gauge.Under this bearing state, measure the maximum outside diameter of oblique wave grommet 1-1, if oblique wave oil distributing ring 1 is before detection through grinding, its maximum outside diameter generally should 0-0.03 millimeter larger than cylinder diameter; If not through grinding, its maximum outside diameter suitably should amplify depending on coating material, makes it after shorter running-in period, the periphery of oblique wave grommet 1-1 and up and down inside and outside scraper ring 1-2 and 1-3 can be fitted with cylinder wall 2-1.Particularly play the position, 1-1-2 place, oiling aperture of main fuel feeding oiling effect, must fit with cylinder wall 2-1, make oiling aperture 1-1-2 be in the state of being closed.Fig. 4 is oblique wave oil distributing ring 1 and the erection drawing of piston 3, cylinder 2.Piston 3 is the combined pistons being provided with cooling oil chamber 3-3, and oblique wave oil distributing ring 1 is just arranged in the cloth oil ring groove between upper and lower Combined gaseous ring.Because the axial height of oblique wave oil distributing ring 1 is consistent with the axial height of oblique wave grommet 1-1, and all a little less than the axial height of joined annular groove, so oblique wave oil distributing ring 1 can freely flick in its annular groove, the inside and outside external cylindrical surface of scraper ring 1-2 and 1-3 and the external cylindrical surface of oblique wave grommet 1-1 all can be attached on cylinder wall 2-1 automatically, and slide on cylinder wall 2-1 with piston together.Ring shaped oil passage 4 between the oblique wave oil distributing ring 1 ring back of the body and cloth oil ring groove bottom surface.The filler opening 3-1 of ring shaped oil passage 4 communicates with the oil-feed mouth of pipe of piston 3 center upper portion, and the return opening 3-2 of ring shaped oil passage communicates with cooling oil chamber 3-3, and the oil return of cooling oil chamber 3-3 flows back to crankcase finally by the drainback passage of piston 3.The machine oil circulating pathway flowing to mark 5 sign with machine oil is: filler opening 3-1 → ring shaped oil passage 4 → return opening 3-2 → cooling oil chamber 3-3.In the process that machine oil flows in ring shaped oil passage 4, mainly through the oiling aperture 1-1-2 on oblique wave grommet 1-1 external cylindrical surface, next is only other hole, machine oil is coated on cylinder wall 2-1, and then by the operation of piston, the first time of oblique wave rubs the overlapping covering role grinding extension and adjacent oil film with the hands, the third time that the second time of inside and outside scraper ring rolls extension effect and compression ring rolls extension effect, final on cylinder wall 2-1, formed evenly within the scope of the whole service of piston, continuously, reliable working oil membrane, thus guarantee piston, piston ring normal operation in the cylinder.What the machine oil due to flowing in ring shaped oil passage 4 adopted is the working method of low-pressure, large discharge, full irrigation formula, no matter so which kind of working position motor is in, can ensure the engine oil supplying oblique wave oil distributing ring 1 of q.s.When motor is in outage state; engine oil pressure disappears; the aperture 1-1-2 playing main fuel feeding effect is attached to again on cylinder wall 2-1; be in closed state; can be very little for total circulation passage of machine oil circulation, and in tiny distribution, capillary and hole suction-operated obvious; so the machine oil retained in oil circuit can not flow into cylinder, storage dormant state can only be in.
