首先对现有技术作简单的介绍（参见图 1、 图 2、 图 3、 图 4、 图 First, a brief introduction to the prior art (see Figure 1, Figure 2, Figure 3, Figure 4, Figure)
5 ), 在现有技术提供的垂直振动轮的典型结构原理图 （图 1和图 2 ) 中， 行走马达 1安装在机架 17上， 行走马达 1的输出端通过减振器 2与振动轮体 3相联接， 激振器壳体 4的两端轴头上装配振动输出轴 承 15， 振动输出轴承 15安装在振动输出轴承座 16 内， 振动输出轴 承座 16再装配在振动轮体 3的内孔的两端辐板上， 激振器壳体 4的 一端轴头通过减振器 1与机架 17相联以保持激振器壳体 4不随振动 轮体 3的滚动而旋转，两根固装有偏心块 6的偏心轴 5通过振动轴承 7和振动轴承座 8在水平方向上并联相对安装在激振器壳体 4内， 所 谓相对安装是指两根固装有偏心块 6的偏心轴 5对称布置在激振器壳 体 4的回转轴线两侧的水平方向上、两才艮偏心轴 5中的偏心块 6的初 始相位角相等， 同步齿轮 9和同步齿轮 10及传动齿轮 11 (同步齿轮 10和传动齿轮 11是双联齿轮）直接安装在偏心轴 5上， 同步齿轮 9 和同步齿轮 10的齿数相等， 传动齿轮 11与输入齿轮 12啮合， 输入 齿轮 12通过联轴器 14和振动马达 13相联接。 现有技术提供的垂直 振动轮（图 1所示）的工作过程是： 振动马达 13通过联轴器 14驱动 输入齿轮 12旋转， 输入齿轮 12啮合驱动传动齿轮 11和同步齿轮 10 旋转、同步齿轮 10又啮合传动同步齿轮 9作和同步齿轮 10的旋向相 反的等速旋转， 即同步齿轮 9和同步齿轮 10驱动两根偏心轴 5作同 步反向旋转，由于两根偏心轴 5的偏心块 6在水平方向上的相对安装， 又由于激振器壳体 4不旋转， 所以， 两根偏心轴 5上的偏心块 6在水 平方向上的激振力相互抵消， 仅产生垂直方向上的激振力， 该激振力 经振动输出轴承 15、 振动输出轴承座 16传递给振动轮体 3， 使振动 轮体 3仅作垂直方向上的振动。 5) In the typical structural schematic diagram of the vertical vibration wheel provided in the prior art (Figs. 1 and 2), the travel motor 1 is mounted on the frame 17, and the output end of the travel motor 1 passes through the damper 2 and the vibration wheel.

The working process of the vertical vibration wheel (shown in FIG. 1) provided by the prior art is: the vibration motor 13 drives the input gear 12 to rotate through the coupling 14, the input gear 12 meshes with the drive transmission gear 11 and the synchronous gear 10 to rotate, and the synchronous gear 10 The meshing transmission synchronizing gear 9 is also engaged with the direction of the synchronizing gear 10 The reverse constant-speed rotation, that is, the synchronizing gear 9 and the synchronizing gear 10 drive the two eccentric shafts 5 for synchronous reverse rotation, due to the relative installation of the eccentric blocks 6 of the two eccentric shafts 5 in the horizontal direction, and the vibration exciter shell The body 4 does not rotate, so the exciting force of the eccentric block 6 on the two eccentric shafts 5 in the horizontal direction cancels each other, and only the exciting force in the vertical direction is generated, and the exciting force is output through the vibration output bearing 15 and the vibration output. The bearing housing 16 is transmitted to the vibrating wheel body 3 to cause the vibrating wheel body 3 to vibrate only in the vertical direction.

When the transmission center distance of 1 0 is reduced to d - 2 f, the rotation axes of the two synchronizing gears 9, 10 are also changed from the parallel state to the intersecting state (outward rotation angle 2 p ).

The typical structural principle of the oscillating vibrating wheel is as shown in FIG. 9. The two eccentric shafts 5 are mounted in parallel by four vibrating bearings 7 in vibration. In the bearing housing 8, the initial phase angles of the eccentric blocks 6 on the two eccentric shafts 5 are 180° apart, and the vibrating bearing housing 8 is mounted in the vibrating spoke plate 27, and is designed at the input ends of the two eccentric shafts 5 installed in parallel. And installing a synchronous gear box (or called a synchronous gear mount) 23, two synchronizing gears 9, 10 and input gear 12 are installed in the synchronizing gear box 23, the synchronizing gears 9, 10 have the same number of teeth, the synchronizing gear The box 23 is positioned at the end of the vibrating bearing housing 8 and is fastened to the vibrating spoke plate 27, and the inner hole of the eccentric shaft 5 is internally splined (or other shaped internal teeth); two synchronizing gears 9 10 with internal spline holes (or other shapes of internal perforations); the coupling 22 is an external spline corresponding to the internal splines or internal teeth of the two eccentric shafts 5 and the two synchronizing gears 9, 10 or External toothed parts, external splines on the coupling 22 or The outer teeth respectively correspond to the inner eccentric shafts of the two eccentric shafts 5 and the two synchronizing gears 9, 10, so as to realize the transmission connection of the eccentric shaft 5 and the synchronizing gears 9, 10, and the transmission centers of the two synchronizing gears 9, 10 The distance is equal to the axial distance of the two eccentric shafts 5, and the two shell-shaped central half shafts 24 are positioned and mounted on the vibrating spoke plate 27, and the central slewing bearing housing 26 is mounted on the shell-shaped central half shaft 24 through the central slewing bearing 25, the center The slewing bearing housing 26 is coupled to the frame 17 by a damper 2 mounted on a shell-like central half shaft 24 through which the oscillating motor 18 is coupled via an input gear 12.
