本发明的实施方式
[0027] 为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图及实施例 , 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅仅用 以解释本发明, 并不用于限定本发明。
[0028] 需要说明的是, 当元件被称为 "固定于"或"设置于"另一个元件, 它可以直接在 另一个元件上或者可能通过第三部件间接固定于或设置于另一个元件上。
[0029] 还需要说明的是, 本实施例中的左、 右、 上、 下等方位用语, 仅是互为相对概 念或是以产品的正常使用状态为参考的, 而不应该认为是具有限制性的。
[0030] 参照图 1、 图 2, 本发明实施例提供的齿轮联动机构, 包括输入齿轮 10、 输出齿 轮 20、 将输入齿轮 10与输出齿轮 20同轴连接的转轴 30以及弹性件 40。 其中, 输 入齿轮 10包括齿形部 11以及位于齿形部 11下方的连接部 12, 输出齿轮 20的中心 设有容纳槽 21, 输入齿轮 10的连接部 12伸入容纳槽 21内。 本实施例中, 容纳槽 2 1的中心设有连接柱 22, 连接部 12底部设有可供连接柱 22伸入的连接孔 (图中未 示出) 。 连接柱 22与连接孔之间间隙配合。 转轴 30依次穿过齿形部 11、 连接部 1 2及连接柱 22而穿出输出齿轮 20外, 且转轴 30与齿形部 11、 连接部 12过盈配合。 弹性件 40预紧卡设于容纳槽 21内, 弹性件 40具有中心孔 41, 连接部 12置于中心 孔 41内, 弹性件 40的内壁上设有凸起 42, 连接部 12的外壁上设有可供凸起 42卡 入的凹槽 13。 [0031] 本发明实施例中, 弹性件 40预紧卡设于容纳槽 21内, 弹性件 40通过凸起 42与凹 槽 13的配合实现输入齿轮 10与输出齿轮 20的连接而随转轴 30转动, 当输出齿轮 2 0与被驱动零件运动遇到阻力吋, 输出齿轮 20停止转动, 而转轴 30与输入齿轮 10 的扭矩不断增加, 当输入齿轮 10的扭矩大于弹性件 40的变形吋, 弹性件 40发生 形变, 凸起 42于凹槽 13中脱离, 输出齿轮 20与弹性件 40停止转动, 而输入齿轮 1 0处于打滑状态而继续空转, 从而自动切断输出齿轮 20的动力传输, 避免输出齿 轮 20或外部障碍物在扭矩与外阻力作用下而受损坏, 可靠性更好。
[0032] 弹性件 40优选采用四弹片 43围合而成。 弹片 43采用具有良好弹性的金属材料制 成, 以为联动机构提供较好的弹力来使保护力矩足够大。 当然, 弹性件 40也可 以为一弹片、 两弹片, 三弹片或更多弹片围合而成。 四个弹片 43在围合吋, 相 互之间无连接, 各弹片 43的两端分别固定于容纳槽 21内侧。 具体地, 容纳槽 21 的内壁上设有可供各弹片 43的两端卡入的卡槽 23。
[0033] 具体地, 容纳槽 21内壁向内凸设有四个凸柱 24, 卡槽 23沿凸柱 24长度方向即高 度方向设置, 且每个凸柱 24上左右对称设置两个卡槽 23。 四个凸柱 24之间间隔 设置, 这样, 一个弹片 43即固定在两个凸柱 24之间。
[0034] 参照图 3、 图 4, 每个凸柱 24的两卡槽 23之间设有卡口 25, 卡口 25与各卡槽 23之 间的壁面 27为圆滑过渡面。 这样, 在安装弹片 43吋, 首先将弹片 43的两端分别 置于相邻凸柱 24的两卡口 25处, 然后沿圆滑过渡面推动弹片 43的端部使弹片 43 的端部卡入凸柱 24的卡槽 23内, 从而将弹片 43固定。
[0035] 本实施例中, 在各凸柱 24的顶面向内延伸限位块 26, 用于限制弹片 43轴向移动 , 防止弹片 43由容纳槽 21内脱出。
[0036] 参照图 1, 弹性件 40上凸起 42的横截面呈 V字型, 凹槽 13的形状与凸起 42的形状 相匹配。 采用这种 V字型, 便于凸起 42卡入凹槽 13内, 也便于凸起 42于凹槽 13内 脱离。 当然, 凸起 42的形状也可以根据需要调整, 如增加凸起 42的高度可提高 保护力矩。
[0037] 参照图 4, 本实施例中, 齿轮联动机构在安装吋, 首先将弹片 43安装于容纳槽 2 1内, 通过凸柱 24上的卡槽 23防止弹片 43脱出, 然后将输入齿轮 10安装在输出齿 轮 20中间的连接柱 22上, 同吋, 使弹片 43的凸起 42与输入齿轮 10的凹槽 13配合 , 使输入齿轮 10与弹片 43之间有一定的预紧力, 避免弹片 43松动。
[0038] 参照图 5, 齿轮联动机构在正常转动吋, 输入齿轮 10通过齿形部 11与外部动力 源啮合, 输出齿轮 20与被驱动零件啮合。 动力源驱动输入齿轮 10转动, 弹片 43 的凸起 42通过预紧力置于凹槽 13内, 此吋, 输入齿轮 10、 弹片 43和输出齿轮 20 作为一个整体转动, 进而带动被驱动零件, 即联动状态。
[0039] 参照图 6, 当被驱动零件运动遇到阻力吋, 输出齿轮 20停止运动, 动力源提供 给输入齿轮 10的扭矩不断增加, 当输入齿轮 10上的扭矩大于弹片 43变形力吋, 弹片 43变形导致三角形凸起 42从输入齿轮 10凹槽 13中转出, 此吋输出齿轮 20和 弹片 43静止, 而输入齿轮 10继续空转, 即打滑状态。
[0040] 本发明还提供了一种齿轮减速器, 其内具有上述的齿轮联动机构。 由于采用上 述的齿轮联动机构, 当输出齿轮 20过载吋, 利用弹片 43的凸起 42与凹槽 13的脱 离调节保护扭矩大小, 保护齿轮减速器不受损伤, 同吋, 齿轮联动机构结构简 单, 体积小, 占用空间少; 而且, 当齿轮减速器应用于智能设备上吋, 利用此 齿轮联动机构, 当输出部分遇到障碍物或负载过大吋, 能自动切断输出, 更能 凸显智能设备的智能与设备保护作用。
[0041] 以上仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明的精神 和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本发明的保护范 围之内。
