Description

一种双锯片电锯用传动机构 技术领域
本发明涉及一种电锯领域， 具体指一种双锯片电锯用传动机构。 背景技术
双锯片电锯 ώ于使用时不需要对切割工件进行支撑即可方便地进行工作，并且切割 震动小、 动作平稳、 切割效率高且操作省力而收到业内人士的欢迎。 现有的双锯片电锯 通常包括用于手握的壳体，所述壳体内设有电机和动力传动机构以及由动力传动机构驱 动的相互平行设置的第一锯片和第二锯片。
为了驱动两个锯片同时反向动作，有的动力传动机构有两组，每组驱动连接一个锯 片； 这种类型的传动机构零部件多， 结构复杂， 壳体的体积也随之变大， 不利于手持操 作。 兼顾到手持操作的特点， 只能缩小传动机构中各零部件的尺寸， 这样对各零部件的 加工精度以及材料要求就提高了很多， 成本随之增加， 且使用寿命会收到一定的影响。
为了克服上述传动机构的特点，人们又研发了凸轮结构的传动机构。这类传动机构 通常包括与电机相连接的一组传动齿轮组， 该齿轮组有两个输出端， 这两个输出端分别 连接两个凸轮或偏心轮， 通过这两个凸轮或偏心轮来分别驱动两个锯片反向转动。 该类 型的传动机构相较于上述采用两组传动机构的类型相比较， 所使用的零部件大大减少， 这样壳体的体积也随之减小， 更有利于电锯的握持； 同时加工成本也有所降低。
众所周知， 对于双锯片电锯来说， 工作时， 两个锯片相对运动的距离越大， 切割效 率越高。 对于第一种类型的双锯片电锯， 由于受到握持操作的限制， 两个锯片相对运动 的距离很难增加。 而对于第二种凸轮或偏心轮驱动的传动机构， 两个锯片相对运动的距 离与凸轮或偏心轮的尺寸有关。 也就是说， 如果要增加两个锯片相对运动的距离， 必须 增大凸轮或偏心轮的尺寸， 并且， ώ于两个偏心轮有一部分是叠加在一起， 如果要将两 个锯片的行程增加一倍， 那么需要将偏心轮的尺寸增大到原来的两倍， 壳体的对应尺寸 片也要增加两倍， 同时壳体的尺寸也受到握持操作的限制。 发明内容
本发明所要解决的技术问题是针对现有技术的现状提供一种不增加壳体尺寸即可 大幅度增大两个锯片相对运动距离的双锯片电锯用传动机构， 从而大幅度提高切割效
- 1 - 确认本 本发明解决上述技术问题所采用的技术方案为：该双锯片电锯用传动机构，包括安 装在壳体内的由电机驱动转动的齿轮传动组、 第一锯片和第二锯片， 其特征在于：
所述第一锯片安装在第一基座上，所述第二锯片安装在第二基座上， 并且所述第一 基座上安装有第一齿条， 所述第二基座上安装有第二齿条， 所述第一齿条和所述第二齿 条同时啮合连接中间齿轮， 所述齿轮传动组的输出端驱动连接所述的第一基座； 所述中 间齿轮的中部设有齿轮轴， 该齿轮轴的两端转动连接在所述壳体上。
传动齿轮组驱动第一齿条往复运动的连接方式有多种，较好的，可以将所述第一齿 条固定连接在所述第一基座的第一表面上，所述第一基座上相背于该第一表面的第二表 面上设有容置槽； 所述齿轮传动组的输出端即末端齿轮上设有偏心轴， 该偏心轴插设在 所述的容置槽内。 该结构简单且不会增加壳体的体积。
上述方案中， 齿轮轴的两端可以直接转动连接在壳体上。作为改进， 所述齿轮轴的 两端分别通过轴承连接所述的壳体。 该结构齿轮轴转动阻力小， 工作稳定性好。
所述传动齿轮组可以有多种啮合连接方式，较好的，所述的传动齿轮组包括与所述 电机的输出轴驱动连接的主动齿轮和与该主动齿轮相啮合的从动齿轮， 该从动齿轮即为 该传动齿轮组的末端齿轮。 该结构更简单， 且传动级数少， 能量损失小。
与现有技术相比，本发明巧妙地采用两个齿条和一个齿轮相配合的方式来驱动第二 齿条相对于第一齿条的反向运动， 以代替驱动第二齿条的凸轮或偏心轮， 这样， 只需要 一个偏心轮即可同时驱动两个锯片反向往复运动， 也就是说， 偏心轴的偏心距离直接对 应锯片的运动行程； 这样， 在不改变壳体尺寸的情况下， 两个锯片的运动行程即可增加 接近一倍； 这样， 在不增加壳体尺寸的情况下实现了大幅度增大两个锯片的运动距离， 从而大幅度提高了切割效率。与两个凸轮驱动的结构相比较，如果增大同样的偏心距离， 那么本发明运动行程的增加则是现有技术的两倍。 附图说明
图 1为本发明实施例的装配结构的立体示意图 (省略了轴承)；
图 2为本发明实施例的装配结构的正视图 (省略了轴承)；
图 3为本发明实施例的使用状态的局部立体结构示意图 (省略了部分壳体)。 具体实施方式
以下结合附图实施例对本发明作进一歩详细描述。
如图 1至图 3所示， 该双锯片电锯用传动机构包括齿轮传动组、设置在传动齿轮组 的上方的第一基座 6和第二基座 7、 第一齿条 8和第二齿条 9以及一中间齿轮 10。
所述传动齿轮组安装在壳体 1内且由电机 2驱动转动，该传动齿轮组包括与电机的 输出轴驱动连接的主动齿轮 3和与该主动齿轮 3相啮合的从动齿轮 4， 该从动齿轮 4即 为该传动齿轮组的末端齿轮。
所述从动齿轮 4上偏心设有偏心轴 5。
所述第一基座 6和第二基座 7相互平行设置，两个基座均为板状结构，其前端设有 用于插设第一锯片 14和第二锯片 15的插槽。
所述第一齿条 8和第二齿条 9分别固定连接在第一基座 6和第二基座 7相对的两个 表面上；
所述中间齿轮 10设置在第一齿条 8和第二齿条 9之间，该中间齿轮 10与第一齿条 8和第二齿条 9同时啮合； 中间齿轮 10的中部设有齿轮轴 11， 该齿轮轴 11的两端通过 轴承 12转动连接在壳体 1壁上。
以第一齿条 8固定连接的所在面为第一基座 6的第一表面，在第一表面的背面即为 第二表面， 该第二表面上设有容置槽 13。 该容置槽 13可以是开设在第一基座 6的第二 表面上的凹槽， 也可以外凸于第二表面。 本实施例为后者。
而所述偏心轴 5容置在容置槽 13内。 该双锯片电锯的工作原理描述如下：
电机 2工作，驱动主动齿轮 3带动从动齿轮 4转动，使设置在从动齿轮 4上的偏心 轴 5在容置槽 13内偏心运动， 从而驱动第一基座 6往复运动。 第一基座 6带动第一锯 片 14往复运动的同时，第一基座 6上的第一齿条 8驱动中间齿轮 10转动， 中间齿轮 10 驱动第二齿条 9带动第二基座 7反向运动， 从而带动第二锯片 15相对于第一锯片 14反 向运动， 完成切割任务。
ώ于传动齿轮组只需要设置一个偏心齿轮即可同时驱动两个锯片相对往复运动，偏 心轴 5的偏心距离直接对应锯片的运动行程， 这样， 稍微增大从动齿轮的尺寸或者稍微 改变一下偏心轴 5的位置， 即可大幅度改变锯条的运动行程， 在不增加壳体尺寸的情况 下实现了大幅度增大两个锯片的运动距离， 从而大幅度提高了切割效率。
