Description

一种具有平衡下落物体速度阻尼器 技术领域
本发明属于阻尼器技术领域，具体涉及一种具有平衡下落物体速度阻尼器。
背景技术
在物体下落过程中，由于重力的作用，这些物体的速度会越来越快。物体在重力加速度的作用下，在短时间内会具有非常大的速度及冲量，因此，通过会设置阻尼器以降低物体的速度和冲量。在建筑的制造领域中，通常会进行物料的输送，若具有自由落体的物料下降，在达到地面时的终端速度和冲量会非常庞大，因此，需设置阻尼器，以降低速度，缓冲冲量。现有阻尼器在下落调整速度过程中，平稳度不够，有必要采用合适方式予以完善，以便获得更好的阻尼效果，平衡物体下落，获得较为平稳的速度。
发明内容
本发明的目的在于提供一种具有平衡下落物体速度阻尼器，便于更好地平衡下落物体的速度，获得较为平稳的下落效果，方便物体高处下落后，平稳下降。
为了实现上述目的，本发明的技术方案如下。
一种具有平衡下落物体速度的阻尼器，包括外壳体，外壳体中固定安装有阻尼构件和齿圈；齿圈设置在阻尼构件上部位置；齿圈中设有三个行星轮，行星轮中均设有行星轮轴，行星轮轴上部采用行星轮轴固定架连接；行星轮中间设有中心太阳轮；中心太阳轮分别与行星轮啮合；中心太阳轮上固定安装有太阳轮转轴；太阳轮转轴穿过中心太阳轮安装设置，中心太阳轮下部采用太阳轮转轴固定安装连接有甩块安装架，甩块安装架设置有三个均匀连接太阳轮转轴侧壁上；甩块安装架外侧为空心腔，空心腔内卡入安装有滑动甩块。
进一步地，行星轮侧面设有齿轮与齿圈内侧的齿轮啮合，中心太阳轮四周的齿轮与行星轮侧面设有齿轮相互啮合。
进一步地，行星轮轴固定架为三角形架，其三个角点与安装在行星轮上的行星轮轴固定连接。
进一步地，阻尼构件内部为空腔，其内腔面采用抛物线设计，由四个凸凹曲线连结形成，滑动甩块贴合在阻尼构件内腔面上。
该发明的有益效果在于：该发明装置能有效地利用阻尼构件中的滑动甩块甩出后，在阻尼构件内腔中摩擦运动，从而控制行星轮在下降过程中运动速度，使得在阻尼器下降过程中，中心太阳轮上输出速度的太阳能转轴获得平衡速度效果，并与平稳速度下落， 使用方便，产品结构简单，安装使用方便。

具体实施方式
下面结合附图和实施例对本发明的具体实施方式进行描述，以便更好的理解本发明。
实施例
如图1、图2和图3所述的具有平衡下落物体速度的阻尼器，包括外壳体1，外壳体1中固定安装有阻尼构件2和齿圈4；齿圈4设置在阻尼构件2上部位置；齿圈4中设有三个行星轮5，行星轮5中均设有行星轮轴6，行星轮轴6上部采用行星轮轴固定架8连接；行星轮5中间设有中心太阳轮7；中心太阳轮7分别与行星轮5啮合；中心太阳轮7上固定安装有太阳轮转轴9；太阳轮转轴9穿过中心太阳轮7安装设置，中心太阳轮7下部采用太阳轮转轴9固定安装连接有甩块安装架10，甩块安装架10设置有三个均匀连接太阳轮转轴9侧壁上；甩块安装架10外侧为空心腔，空心腔内卡入安装有滑动甩块3。行星轮5侧面设有齿轮与齿圈4内侧的齿轮啮合，中心太阳轮7四周的齿轮与行星轮5侧面设有齿轮相互啮合；如图2所示。行星轮轴固定架8为三角形架，其三个角点与安装在行星轮5上的行星轮轴6固定连接，如图2所示。阻尼构件2内部为空腔，其内腔面采用抛物线设计，由四个凸凹曲线连结形成，如图3所示，滑动甩块3贴合在阻尼构件2内腔面上。
该发明中，阻尼构件2内部为空腔，其内腔面采用抛物线设计，滑动甩块3贴合在阻尼构件2内腔面上。随着该发明下落过程中，滑动甩块3在阻尼构件2内部的腔体中移动，随着阻尼器下落，在甩块安装架10转动过程中，滑动甩块3随着甩块安装架10内的空腔作用，贴合在阻尼构件2内腔面上。当滑动甩块3处于阻尼构件2内腔面的凸面时，滑动甩块3被挤压到阻尼构件2内部的腔体中；当滑动甩块3处于阻尼构件2内腔面的凹面时，滑动甩块3从阻尼构件2内部的腔体中伸出，贴合在滑动甩块3内腔面上。在这个过程中，甩块安装架10的转动保持平稳速度，带动中心太阳轮7带动，从而带动三个行星轮5带动，使得整个阻尼器保持平稳下落，实现平衡功能。
如图3所示，根据离心力推导式离心力F＝滑块质量*运动速度*运动速度/半径，即F＝mV 2/R，因此，阻尼力与滑块重量和速度正比，与变化的半径成反比，如图3所示，R2为太阳轮转轴9外表面与阻尼构件2内表面最远处，R1为太阳轮转轴9外表面与阻尼构件2内表面最近处，滑动甩块3在与阻尼构件2内表面无摩擦接触中，在离心的作用沿曲线轨迹运行。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
