DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Such as Figures 1 to 7As shown in the figure, a wear-resistant alloy steel component includes a cylindrical main body made of alloy steel material and a mating connection seat 1. On the upper and lower edges of the mating connection seat 1, there are overall mating chamfer structures 2 respectively, which make the structural safety at the outer edge position better. At the center position of the lower end of the mating connection seat 1, there is a cylindrical center combined connection hole 3. At the center position of the upper end of the mating connection seat 1, there is a cylindrical center mating stop hole 4 that communicates with the center combined connection hole 3 and has a diameter smaller than that of the center combined connection hole 3. The upper and lower sides are inserted and combined with the ends of two shaft components with different diameters, which can provide a mating limit function during use and ensure higher bearing strength at the mating position during the subsequent movement and mating of the shaft components. On the upper end of the mating connection seat 1, there are overall fastening connection holes 5 evenly distributed in a circle, through which overall fastening and locking are carried out. On the upper end of the mating connection seat 1, there is a lubrication safety delivery groove 6 that connects the inside and outside, which can realize the delivery and mating of lubricating fluid inside and outside. At the upper end of the center mating stop hole 4, there is a lubrication mating safety groove 7, and the lower end of the lubrication mating safety groove 7 is a conical structural surface. At the upper end of the center combined connection hole 3, there is a center stop lubrication mating groove 8 with a V-shaped cross-section, so that better lubrication mating can be achieved at both internal mating positions, and the shaft components in mating can be lubricated more comprehensively and safely during use, and the overall wear resistance during use is better. The upper end of the center stop lubrication mating groove 8 is a horizontal plane, which is easier during production and processing. It is provided with a lubrication structure at the installation positions of two mutually mating shaft components inside, which can be used in cooperation with lubricating fluid during use to achieve precise and safe lubrication of the mating positions of the internal moving components. The overall wear resistance during use is better, and the overall service life during use is longer. At the upper end position, by setting a lubrication transition groove that connects the inside and outside, the mating effect of lubrication flow inside and outside can be achieved during use, the overall lubrication during use is more comprehensive, and the mating safety during use is higher.
[0021] Preferably, the cross-section of the lubrication safety delivery groove 6 is an arc-shaped structure, and the fluidity during the delivery and mating of the lubricating fluid is better.
[0022] Preferably, the depth of the lubrication safety delivery groove 6 at the position closer to the overall central axis is greater than that at the outer side position, so that its internal is a conical structural surface, which can further improve the lubrication fluidity during use and the mating safety during use is also better.
[0023] Preferably, the depth of the intersection position of the lubrication safety delivery groove 6 and the lubrication mating safety groove 7 is less than the depth of the lubrication mating safety groove 7, and the influence of the internal position on the overall strength is smaller, so that the overall structural durability is relatively higher.
[0024] Preferably, an installation combination convenient chamfer structure is provided at the outer edge position of the central combination connection hole 3, which is more convenient during assembly and combination, has the function of guiding the fit, can improve the fit efficiency during combination, and makes the fit operation more convenient.
