Description

精密摆线回转关节减速器 技术领域
本发明涉及一种精密摆线减速器,是用于机器人回转关节、机床转台等要求高回转精度场合的装置。
背景技术
BXJ减速器是在摆线针轮基础上发展起来的一种新型传动装置,具有刚度大、传动比范围大、承载能力大、运动精度高、传动效率高和回差小、体积小等一系列优点。
BXJ减速器由渐开线圆柱行星减速机构和摆线针轮机构两部分组成。由于摆线针轮传动部分是该减速器的输出构件,因而对减速器的运动精度和回差影响最直接,也最大。为了保证BXJ减速器的运动精度和回差,通常将针齿销、针齿销孔以及摆线轮间的配合间隙预留得很小,然而减速器运行后,温度会有一定幅度上升,由于材料的热膨胀,配合间隙将进一步缩小,针齿销将很难转动甚至卡死,此时摆线轮与针齿间是滑动摩擦,而非滚动摩擦,进而大幅降低减速器的传动效率和使用寿命。为了解决这一矛盾问题,通常通过提高针齿销,针齿销孔以及摆线轮的加工精度以控制配合间隙,这是BXJ减速器制造成本高的主要原因。
发明内容
本发明的目的在于提供一种结构合理、造价低、高传动效率和使用寿命、高运动精度、回差小的精密摆线回转关节减速器。
本发明的技术方案:一种精密摆线回转关节减速器,包括针齿壳、行星架、曲柄轴、针齿销、摆线轮、中心齿轮和行星轮,行星架经滚动轴承穿接支撑在针齿壳内,曲柄轴穿设在行星架内且具有错位180°的两个偏心部,其偏心部通过滚子轴承与摆线轮联接,摆线轮经容纳于针齿壳内壁针齿销孔内的针齿销啮合在针齿壳内,曲柄轴两端通过圆锥滚子轴承支撑在行星架内且通过花键和挡圈固联 行星轮,两个以上曲柄轴、摆线轮与行星架构成平行四边形机构,中心齿轮与行星轮啮合;其特征在于:所述摆线轮齿廓的齿顶区域、啮合区域和齿根区域组成一条顺滑曲线,啮合区域啮合针齿销,齿顶区域和齿根区域与针齿销存在间隙,所述针齿销孔直径大于针齿销直径,针齿销的外圆内切与针齿销孔,所述摆线轮啮合区域和针齿销的公法线方向存在间隙。
进一步,所述针齿销数目比摆线轮的齿数至少多1。
本发明将针齿销孔加大,让针齿销能够在其对应针齿销孔内自由转动,同时将针齿销对应销孔沿径向方向,向针齿壳圆心方向移动,设针齿销与其对应针齿销孔间出现间隙δ,针齿销孔移动δ/2的距离,使得针齿销的外圆内切于其对应销孔,补偿了预留的运动间隙,沿针齿销和摆线轮公法线方向却存在间隙,热膨胀后,摆线轮的齿廓各点近似沿其法线方向变化,由于销孔沿针齿销和摆线轮公法线方向存在间隙,针齿销始终能够在其对应孔内自由旋转。针齿销与其对应针齿销孔间呈外大里小的间隙,便于润滑油脂的进入,使得减速器运行过程中,针齿销始终能够得到充分的润滑,从而确保针齿销与摆线轮间始终是滚动摩擦,因而提高了减速器传动效率和使用寿命。
将摆线轮的齿形进行修形,摆线轮齿廓中法线方向与径向接近的区域,即齿顶和齿根区域进行修形,以避免材料热膨胀后与摆线轮与针齿销干涉将摆线轮齿廓分为齿顶区域、齿根区域以及啮合区域组成一条顺滑组合曲线,使用时齿顶区域与齿根区域与针齿销间有一定间隙,其余区域与针齿销啮合。这样,仅有摆线轮的齿顶和齿根区域不参与啮合,其余部分由于是标准齿形,均参与啮合。由于同时参与啮合的齿数多,提高了承载能力,且有利于发挥误差均化作用,提高传动精度的同时降低了加工和装配的要求,进而降低了减速器的制造成本。
