Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1-Figure 3, a kind of engine crankshaft thrust device, thrust entirety is semi-circle structure, forms primarily of thrust bearing body 1, thrust ring 8 and thrust ring fixed block 5.Thrust ring 8 is wherein provided with two, corresponding, thrust ring fixed block 5 is also provided with two, the monnolithic case of described thrust ring fixed block 5 is in " recessed " font, the projection at its two ends is stepped, protruding thickness is less than other segment thicknesses, is also provided with two through holes 9, as shown in Figure 4, Figure 5 in the relatively thick end of two ends projection.In order to fixedly mount thrust ring fixed block 5, corresponding with through hole 9 is, at two end faces of thrust bearing body 1, two tapped holes are set respectively, therefore, thrust ring fixed block 5 bolt 6 can be utilized to run through through hole 9 and with form screw thread between thrust bearing body 1 and be flexibly connected, thus facilitate the installation and removal of thrust ring 8; After thrust ring fixed block 5 and thrust bearing body 1 fixedly mount, the projection at thrust ring fixed block 5 two ends compresses thrust ring 8, thus is fixed on thrust bearing body 1 by thrust ring 8, prevents thrust ring 8 from rotating, and reaches the object that thrust ring 8 radial direction is fixing.
In order to thrust ring 8 fixing after stable, reliably, thrust bearing body 1 inside is provided with bearing support groove 13, circumferentially projection is provided with at thrust ring 8, as shown in Figure 3, bearing support groove 13 is positioned at the arc shaped inside of thrust bearing body 1, and the both sides of bearing support groove 13 are also provided with stepped projection, two thrust rings 8 lay respectively at the both sides of bearing support groove 13, and be fixed in bearing support groove 13 by thrust ring fixed block 5, thrust ring 8 projection circumferentially and the mutual snap-fit engagement of stepped projection of bearing support groove 13 both sides, so advantageously in the axial displacement preventing thrust ring 8, ensure the thrust function that crankshaft thrust is good.In order to crankshaft thrust can facilitate, be arranged on engine external body quickly, save engine body inner space, thrust bearing body 1 is provided with 8 to 10 through bolts hole 10, these bolts hole 10 are uniformly distributed along the outer end circumferencial direction of thrust bearing body 1, utilize bolt thrust bearing body 1 can be fixedly mounted on engine external body by bolt hole 10, what ensure thrust bearing body 1 and engine body is fixedly connected with intensity simultaneously, in the course of the work, make thrust bearing body 1 uniform force in a circumferential direction, ensure the functional reliability of crankshaft thrust entirety, stability.
In crankshaft thrust working procedure, the sufficient lubrication of crankshaft thrust inside must be ensured, for this reason, thrust bearing body 1 be provided with bearing support oil duct 12.As shown in Figure 3, described bearing support oil duct 12 is inner through thrust bearing body 1, its entrance point is the first lubrication hole 2 being arranged on thrust bearing body 1 body attachment face, outlet end is then the second lubrication hole 14 being opened in thrust bearing body 1 internal surface, the end process hole of bearing support oil duct 12 utilizes stifled 11 sealings of oil, oil stifled 11 is positioned at the inner side arcuate surface of thrust bearing body 1, for the ease of cleaning, the maintenance of crankshaft thrust, oil is stifled is that screw thread is flexibly connected between 11 with thrust bearing body 1, the installation of convenient oil stifled 11, dismounting.Meanwhile, offer oil groove 4 in the side of thrust ring 8, the curved shape of described oil groove 4, and ring thrust ring 8 circle distribution, oil groove 4 is provided with 6 to 9 oilholes 3, the through thrust ring 8 of oilhole 3, and all oilholes 3 are uniformly distributed along oil groove 4; Groove 7 is offered at the opposite side of thrust ring 8, described groove 7 is linearly, and along thrust ring 8 radially direct, even in order to ensure the internal lubrication of crankshaft thrust, groove 7 offer the quantity that quantity is not less than oilhole 3, and the oil groove 4 of the through thrust ring 8 of each oilhole 3 and groove 7.Arc oil groove 4 is wherein conducive to the water conservancy diversion of lubricant oil on thrust ring 8, and groove 7 is conducive to the directional flow of lubricant oil under self gravitation effect, is convenient to the draining of crankshaft thrust internal lubrication oil.Therefore, said structure can ensure the supply of lubricating oil amount needed for crankshaft thrust internal lubrication, and the supply of the lubricating oil of each several part is substantially even, more ensure that the inner loop of crankshaft thrust internal lubrication oil.
After crankshaft thrust of the present invention and engine body are in place, relative thirty years of age of face, groove 7 place on two thrust rings 8 in crankshaft thrust, the first lubrication hole 2 in crankshaft thrust is corresponding with the lubricating oil oil duct of engine body connect through, for the lubricating oil of engine body is imported to crankshaft thrust inside, second lubrication hole 14 is corresponding through with the oil groove 4 on one of them thrust ring 8, thus the lubricating oil in bearing support oil duct 12 is imported thrust ring 8, lubricating oil for thrust ring 8 supplies, end process hole stifled 11 sealings of oil of bearing support oil duct 12, under the cooperation of groove 7, make the lubricant oil of motor can carry out sufficient lubrication by bearing support oil duct 12 to whole crankshaft thrust inside, thus achieve the internal lubrication of crankshaft thrust.By arranging bolt hole 10 on thrust bearing body 1, utilize bolt crankshaft thrust can be fixedly mounted on easily the engine body exterior of motor, and dismounting easily.In addition, because thrust ring 8 is provided with two, be all fixed on thrust bearing body 1 inside by thrust ring fixed block 5, stop circumferential rotation and the radial-play of thrust ring 8, thus the circumferencial direction realized after crankshaft thrust ring 8 installation and radial fixing.In a word, crankshaft thrust of the present invention can guarantee the sufficient lubrication of the axial restraint that engine crankshaft is good and crankshaft thrust inside, ensure that the stability of bent axle in operation process, reliability, reduce the vibrations noise in crankshaft operation process, and guarantee the output power of engine stabilizer, extend the working life of bent axle and related components.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, it should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
