具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本发明内涵的情况下做类似改进,因此发明不受下面公开的具体实施的限制。
需要说明的是,当元件被称为“固定于”另一个元件,它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件,它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的,并不表示是唯一的实施方式。
在本实施例中,详情参考图1-图6所述,提供一种动平衡旋转驱动组件,能够减小系统中高速转动下,而引发的系统振动,从而减少不平衡量。具体地包括,载具1和驱动部2,载具1具有传动圈11,传动圈11设置在载具1底面,且位于中心位置,驱动部2包括驱动齿盘21,驱动齿盘21与驱动装置连接,具体如图2所示,驱动齿盘21与位于其下方的驱动电机的输出轴驱动连接。通过该方式,驱动电机带动驱动齿盘21高速转动,同时驱动齿盘21与传动圈11同轴设置且传动连接,从而就可以实现载具1的高速转动,当然载具1还具有定位卡槽12,定位卡槽12设置在载具1上表面,用于夹具移动,方便夹具固定被检测件。
当然为了进一步地减少高速系统中的,系统振动;还包括线接触圈3,线接触圈3包括摩擦圈31和转轴32,为了方便转轴32安装,在驱动齿盘21具有安装孔211,安装孔211设置在齿端上,转轴32固定安装在所述安装孔211中,摩擦圈31转动安装在转轴32上,且与传动圈11啮合。实际运用中,将原来的渐开线接触方式改变成转动接触,摩擦圈31由于是转动安装,一旦接触时,摩擦圈31将会产生转动,这样一来,这样就减少了驱动齿盘21与传动齿啮合过程的中单一位置的接 触时间,进而减少了两者接触产生的振动。
同时为了方便摩擦圈31与传动圈11啮合,在传动圈11还具倒锥圆弧齿牙111,倒锥圆弧齿牙111设置在传动圈11下端面,倒锥圆弧齿牙111与摩擦圈31啮合。在实际运用中,摩擦圈31与倒锥圆弧齿牙111的圆形啮合方式,在啮合过程中,由于摩擦圈31与倒锥圆弧齿牙111的圆形啮合接触面大,能够传递较多的功率,避免了浪费。同时,倒锥圆弧齿牙111设置在传动圈11下端面,在实际使用时,啮合传动过程中产生的物质会直接掉落,就不会产生过多的杂质积存影响传动效率。
为了进一步使得,摩擦圈31传递效能增大,并能同时减少由于设置不均匀,而导致的系统振动,将摩擦圈31设置为包括外圈311和内圈312,外圈311与所述内圈312分别转动在转轴32的内外两端。这样一来就使得系统振动减少。
当然了为了防止驱动齿盘21轴向传动而引发传动失效,还包括滑动球,为了方便滑动球4滑动,在驱动齿盘21还具有上环形滑槽212,上环形滑槽212设置在驱动齿盘21中,载具1还具有下环形滑槽13,滑动球4分别在所述上环形滑槽212和上环形滑槽212中滑动。这样一来,就能有效防止驱动齿盘21轴向传动而引发传动失效。
综上所述,该一种动平衡旋转驱动组件,能够减小系统中高速转动下,而引发的振动,从而减少不平衡量。同时,能够使用较少的传动零件用于传动,并通过下凹半圆形与摩擦圈31,提高传动效率,同时增加的摩擦圈31转动安装,使得摩擦圈31在与传动圈11接触时,减少振动。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点,对于本领域技术人员而言,显然本发明不限于上述示范性实施例的细节,而且在不背离本发明的精神或基本特征的情况下,能够以其他的具体形式实现本发明。因此,无论从哪一点来看,均应将实施例看作是示范性的,而且是非限制性的,本发明的范围由所附权利要求而不是上述说明限定,因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉 及的权利要求。
此外,应当理解,虽然本说明书按照实施方式加以描述,但并非每个实施方式仅包含一个独立的技术方案,说明书的这种叙述方式仅仅是为清楚起见,本领域技术人员应当将说明书作为一个整体,各实施例中的技术方案也可以经适当组合,形成本领域技术人员可以理解的其他实施方式。
