The steering drive assembly is an important component of the lawn mower, mainly used to drive the lawn mower to move and turn.
转向驱动组件包括壳体以及安装在壳体内的减速齿轮机构，但是现有技术的减速齿轮机构只有三级，即通过输入轴齿轮、中间轴齿轮以及输出轴齿轮三者来进行传动，这样其扭矩分配不均衡，可能导致噪音会较大，并且啮合点较少，所以也可能导致整体精度较低；而且因为现有技术的转向驱动组件中壳体组成比较复杂，由中部壳体加两侧的两个盖板三个部分组成，这样就需要先将减速齿轮组安装到中部壳体内，然后在分别安装好两侧的盖板，整体安装效率较低。The steering drive assembly includes a housing and a reduction gear mechanism installed in the housing. However, the reduction gear mechanism in the prior art has only three stages, namely, transmission is performed through an input shaft gear, an intermediate shaft gear and an output shaft gear. This results in an unbalanced torque distribution, which may lead to loud noise and fewer meshing points, and may also lead to lower overall accuracy. In addition, because the housing composition of the steering drive assembly in the prior art is relatively complex, consisting of a middle housing and two cover plates on both sides, it is necessary to first install the reduction gear set into the middle housing, and then install the cover plates on both sides respectively, resulting in low overall installation efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
一种转向驱动组件，如图1所示，包括壳体、分别设置在壳体两侧的驱动电机3以及设置在壳体内的减速齿轮机构，其中：A steering drive assembly, as shown in FIG1 , comprises a housing, a drive motor 3 disposed on both sides of the housing, and a reduction gear mechanism disposed in the housing, wherein:
壳体，包括左壳体1与右壳体2，两者是对称设置的，所以结构是一样的，如图5所示，左壳体1与右壳体2内部均设置有两个安装孔16、一个伸入孔17以及一个安装腔18，其中，两个安装孔16分别是用于安装第一中间轴5与第二中间轴6，一个伸入孔17是供电机轴伸入的，安装腔18是用于安装输出轴7的；The housing includes a left housing 1 and a right housing 2, which are symmetrically arranged, so the structures are the same. As shown in FIG5 , two mounting holes 16, an insertion hole 17 and a mounting cavity 18 are arranged inside the left housing 1 and the right housing 2, wherein the two mounting holes 16 are used to install the first intermediate shaft 5 and the second intermediate shaft 6, respectively, the insertion hole 17 is for the motor shaft to be inserted, and the mounting cavity 18 is used to install the output shaft 7;
驱动电机3，为现有技术的电机，有两个，分别安装在左壳体1与右壳体2上，其电机轴从左壳体1和右壳体2上的伸入孔17伸入与减速齿轮机构传动，伸入到壳体内的电机轴可以作为输入轴4使用，这样就不需要再设置额外的输入轴4了；The driving motor 3 is a motor of the prior art, and there are two of them, which are respectively mounted on the left housing 1 and the right housing 2. The motor shafts thereof extend from the insertion holes 17 on the left housing 1 and the right housing 2 to be transmitted with the reduction gear mechanism. The motor shafts extending into the housing can be used as the input shaft 4, so that there is no need to set an additional input shaft 4.
减速齿轮机构，包括两个减速齿轮组，两个减速齿轮组对称设置，并且共用第一中间轴5与第二中间轴6，减速齿轮组包括输入轴4、第一中间轴5、第二中间轴6以及输出轴7，第一中间轴5以及第二中间轴6的两侧是容置在两个安装孔16内，输出轴7是容置在安装腔18内，并且第一中间轴5与第二中间轴6是可以自由转动，且输入轴4上套设有输入齿轮8，第一中间轴5上套设有第一大齿轮10与第一小齿轮11，第二中间轴6上套设有第二大齿轮12与第二小齿轮13，输出轴7上套设有输出齿轮9，且输入齿轮8与第一大齿轮10啮合，第一小齿轮11与第二大齿轮12啮合，第二小齿轮13与输出齿轮9啮合，并且输入轴4与电机轴是两者一体成型的，即可以将电机轴作为输入轴4。The reduction gear mechanism comprises two reduction gear sets, which are symmetrically arranged and share a first intermediate shaft 5 and a second intermediate shaft 6. The reduction gear set comprises an input shaft 4, a first intermediate shaft 5, a second intermediate shaft 6 and an output shaft 7. Both sides of the first intermediate shaft 5 and the second intermediate shaft 6 are accommodated in two mounting holes 16, the output shaft 7 is accommodated in a mounting cavity 18, and the first intermediate shaft 5 and the second intermediate shaft 6 can rotate freely. An input gear 8 is sleeved on the input shaft 4, a first large gear 10 and a first small gear 11 are sleeved on the first intermediate shaft 5, a second large gear 12 and a second small gear 13 are sleeved on the second intermediate shaft 6, an output gear 9 is sleeved on the output shaft 7, and the input gear 8 is meshed with the first large gear 10, the first small gear 11 is meshed with the second large gear 12, and the second small gear 13 is meshed with the output gear 9. The input shaft 4 and the motor shaft are integrally formed, that is, the motor shaft can be used as the input shaft 4.
减速齿轮组的工作原理是：驱动电机3工作，带动输出齿轮9转动，然后输出齿轮9带动第一大齿轮10转动，第一大齿轮10带动第一中间轴5转动，第一中间轴5带动第一小齿轮11转动，第一小齿轮11带动第二大齿轮12转动，第二大齿轮12带动第二中间轴6转动，第二中间轴6带动第二小齿轮13转动，最后第二小齿轮13带动输出轴7转动，实现了电机带动输出轴7转动，并且因为设置的齿轮较多，这样扭矩更加均衡，并且啮合点较多，精度也较高。The working principle of the reduction gear set is: the driving motor 3 works, driving the output gear 9 to rotate, and then the output gear 9 drives the first large gear 10 to rotate, the first large gear 10 drives the first intermediate shaft 5 to rotate, the first intermediate shaft 5 drives the first small gear 11 to rotate, the first small gear 11 drives the second large gear 12 to rotate, the second large gear 12 drives the second intermediate shaft 6 to rotate, the second intermediate shaft 6 drives the second small gear 13 to rotate, and finally the second small gear 13 drives the output shaft 7 to rotate, thereby realizing that the motor drives the output shaft 7 to rotate, and because more gears are set, the torque is more balanced, and there are more meshing points and higher precision.
与实施例一的区别在于，实施例二中两个第一小齿轮11之间设置有第一隔板14，即在第一中间轴5中部套设有第一隔板14，这样可以防止两个第一小齿轮11之间相互干扰；两个第二大齿轮12之间设置有第二隔板15，即在第二中间轴6中部套设有第二隔板15，这样也可以防止两个第二大齿轮12之间相互干扰。The difference from the first embodiment is that in the second embodiment, a first partition plate 14 is arranged between the two first small gears 11, that is, the first partition plate 14 is sleeved on the middle part of the first intermediate shaft 5, so as to prevent the two first small gears 11 from interfering with each other; a second partition plate 15 is arranged between the two second large gears 12, that is, the second partition plate 15 is sleeved on the middle part of the second intermediate shaft 6, so as to prevent the two second large gears 12 from interfering with each other.
如图6与图7所示，与实施例一的区别在于，实施例三中第一小齿轮11一侧设置有第一延伸齿20，且第一大齿轮10是啮合在第一延伸齿20上的，相当于第一大齿轮10并没有直接套设在第一中间轴5上，而是套设在第一延伸齿20上，这样第一小齿轮11与第一大齿轮10之间可以直接带动，不需要经过第一中间轴5中转；第二小齿轮13一侧设置有第二延伸齿21，且第二大齿轮12是啮合在第二延伸齿21上的，相当于第二大齿轮12并没有直接套设在第二中间轴6上，而是套设在第二延伸齿21上，这样第二大齿轮12与第二小齿轮13之间可以直接带动，不需要经过第二中间轴6中转。As shown in FIG6 and FIG7, the difference from the first embodiment is that in the third embodiment, a first extension tooth 20 is provided on one side of the first pinion 11, and the first large gear 10 is meshed on the first extension tooth 20, which is equivalent to that the first large gear 10 is not directly sleeved on the first intermediate shaft 5, but sleeved on the first extension tooth 20, so that the first pinion 11 and the first large gear 10 can be directly driven without passing through the first intermediate shaft 5; a second extension tooth 21 is provided on one side of the second pinion 13, and the second large gear 12 is meshed on the second extension tooth 21, which is equivalent to that the second large gear 12 is not directly sleeved on the second intermediate shaft 6, but sleeved on the second extension tooth 21, so that the second large gear 12 and the second pinion 13 can be directly driven without passing through the second intermediate shaft 6.
与实施例一的区别在于，实施例四中安装腔18外部的壳体上设置有加强筋19，因为输出轴7比较长，所以导致了安装腔18也比较长，如果没有设置加强筋19，这样这部分壳体整体强度较低，增加了加强筋19之后这部分壳体整体强度较高，不容易变形损坏。The difference from the first embodiment is that in the fourth embodiment, a reinforcing rib 19 is provided on the shell outside the installation cavity 18. Because the output shaft 7 is relatively long, the installation cavity 18 is also relatively long. If the reinforcing rib 19 is not provided, the overall strength of this part of the shell is relatively low. After adding the reinforcing rib 19, the overall strength of this part of the shell is higher and it is not easy to be deformed and damaged.
