Description

一种精密行星齿轮减速机 技术领域
本实用新型属于机械技术领域，涉及一种齿轮减速机，特别是一种精密行星齿轮减速机。
 背景技术
精密行星减速机是行业内对行星减速机的另一种称呼，它的主要传动结构为：行星轮，太阳轮，内齿圈。相对其他减速机，精密行星减速机具有高刚性、高精度（单级可做到1分以内）、高传动效率(单级在97%-98%)、高的扭矩/体积比、终身免维护等特点。多数是安装在步进电机和伺服电机上，用来降低转速，提升扭矩，匹配惯量。
为避免精密行星减速机的输出轴在安装时出现轴向间隙导致传动时发生轴向晃动，现有做法是采用多根螺栓部件固连输出轴和传动部件，以锁紧输出轴，由于螺栓有多根且安装时需要对孔位，操作较为不便。
 技术问题
本实用新型的目的是针对现有的技术存在上述问题，提出了一种便于组装的精密行星齿轮减速机。
 技术解决方案
本实用新型的目的可通过下列技术方案来实现：一种精密行星齿轮减速机，包括呈筒形的箱体和水平转动设于箱体内的输入轴和输出轴，输入轴和输出轴同轴，输出轴左端伸出箱体，输入轴左端具有太阳轮，箱体内壁上成型有齿圈，太阳轮和齿圈之间啮合有行星轮，行星轮与输出轴连接，其特征在于，输出轴通过左轴承和右轴承与箱体转动连接，且行星轮处于左轴承和右轴承之间；箱体左端口内设有与输出轴同轴的锁紧环，锁紧环套在输出轴外，锁紧环外壁和箱体密封固连，锁紧环内壁通过油封与输出轴之间形成密封；锁紧环右端紧压在左轴承外圈上，且输出轴上具有供左轴承内圈右端紧压的轴肩；输出轴右端和箱体内壁上分别具有与输出轴同轴的环形抵压面一和环形抵压面二，右轴承的内圈左端和外圈右端分别紧压在环形抵压面一和环形抵压面二上。
设于箱体左端口内的锁紧环紧压在左轴承上，使输出轴具有向右移动趋势，使右轴承始终限位在环形抵压面一和环形抵压面二上，以有效消除输出轴的轴向运动间隙，避免传动过程中出现轴向晃动，来提高传动稳定性和精度。
本申请只需在箱体左端口装入锁紧环便可消除输出轴在轴向上的运动间隙，相对于现有技术中通过多根螺栓等部件锁紧输出轴，具有组装方便的优点。
在上述的精密行星齿轮减速机中，上述的锁紧环外壁通过螺纹结构与箱体密封固连，这样转动锁紧环可使其右移，促使锁紧环更紧密地压在左轴承上，组装更为便利、轻松。
在上述的精密行星齿轮减速机中，锁紧环上具有呈轴向设置的插孔，插孔为盲孔，且插孔孔口朝左设置，插孔至少有两个并沿锁紧环周向均布。插孔用于与工具配合来转动锁紧环，这样在实际产品中，可有效减少锁紧环在箱体外的长度，使整个结构较为紧凑。
作为另一种方案，在上述的精密行星齿轮减速机中，锁紧环外壁的形状和尺寸均与箱体左端口内壁匹配，且锁紧环外壁和箱体紧密配合固连。
在上述的精密行星齿轮减速机中，箱体包括均呈筒状且同轴的左箱体和右箱体，且左箱体和右箱体密封固连，输入轴和输出轴分别位于右箱体和左箱体上，左箱体和右箱体之间形成轴向截面呈“凵”形的环形槽，环形槽包括正对设置的左侧壁和右侧壁，右侧壁为上述的环形抵压面二，左侧壁紧压在右轴承外圈左端上。采用上述设计，既可进一步定位右轴承，又对右轴承的安装进行导向，提高组装方便性。
在上述的精密行星齿轮减速机中，输入轴和太阳轮为一体式结构，以确保最大的扭转刚性及高输入转速下的零背隙动力传递。
 有益效果
与现有技术相比，本精密行星齿轮减速机具有以下优点：
1、设于箱体左端口内的锁紧环紧压在左轴承上，使输出轴具有向右移动趋势，使右轴承始终限位在环形抵压面一和环形抵压面二上，以有效消除输出轴的轴向运动间隙，避免传动过程中出现轴向晃动，来提高传动稳定性和精度。
2、本申请只需在箱体左端口装入锁紧环便可消除输出轴在轴向上的运动间隙，相对于现有技术中通过多根螺栓等部件锁紧输出轴，具有组装方便的优点。

 本发明的最佳实施方式
以下是本实用新型的具体实施例并结合附图，对本实用新型的技术方案作进一步的描述，但本实用新型并不限于这些实施例。
实施例一
如图1所示，本精密行星齿轮减速机包括呈筒形的箱体1和水平转动设于箱体1内的输入轴2和输出轴3。其中，输入轴2和输出轴3同轴；输出轴3左端伸出箱体1，输入轴2通过滚动轴承与箱体1转动连接，该输入轴2左端具有太阳轮2a，且优选输入轴2和太阳轮2a为一体式结构，以确保最大的扭转刚性及高输入转速下的零背隙动力传递。
具体来说，如图1和图2所示，箱体1内壁上成型有齿圈，齿圈和输入轴2同轴，且太阳轮2a位于齿圈内侧。太阳轮2a和齿圈之间啮合有行星轮4，行星轮4与输出轴3连接。在本实施例中，行星轮4有3个并沿齿圈周向分布，每个行星轮4均通过销轴与输出轴3固连。如图1所示，输出轴3通过左轴承5和右轴承6与箱体1转动连接，且行星轮4处于左轴承5和右轴承6之间。箱体1左端口内设有与输出轴3同轴的锁紧环7，锁紧环7套在输出轴3外，锁紧环7外壁和箱体1密封固连，锁紧环7内壁通过油封8与输出轴3之间形成密封，此时，油封8套在输出轴3外，且油封8内侧壁和外侧壁分别与输出轴3侧壁和锁紧环7内壁相抵。锁紧环7右端紧压在左轴承5外圈上，且输出轴3上具有供左轴承5内圈右端紧压的轴肩3a。输出轴3右端和箱体1内壁上分别具有与输出轴3同轴的环形抵压面一3b和环形抵压面二1c1，右轴承6的内圈左端和外圈右端分别紧压在环形抵压面一3b和环形抵压面二1c1上。设于箱体1左端口内的锁紧环7紧压在左轴承5上，使输出轴3具有向右移动趋势，使右轴承6始终限位在环形抵压面一3b和环形抵压面二1c1上，以有效消除输出轴3的轴向运动间隙，避免传动过程中出现轴向晃动，来提高传动稳定性和精度。
其中，锁紧环7安装方式如下：锁紧环7外壁通过螺纹结构与箱体1密封固连，这样转动锁紧环7可使其右移，促使锁紧环7更紧密地压在左轴承5上，组装更为便利、轻松。进一步说明，锁紧环7上具有呈轴向设置的插孔7a，插孔7a为盲孔，且插孔7a孔口朝左设置，插孔7a至少有两个并沿锁紧环7周向均布。插孔7a用于与工具配合来转动锁紧环7，这样在实际产品中，可有效减少锁紧环7在箱体1外的长度，使整个结构较为紧凑。
在本实施例中，箱体1包括均呈筒状且同轴的左箱体1a和右箱体1b，且左箱体1a和右箱体1b密封固连。优选左箱体1a和右箱体1b之间设置使两者之间形成密封的密封圈9，且左箱体1a和右箱体1b通过螺栓固连。输入轴2和输出轴3分别位于右箱体1b和左箱体1a上，左箱体1a和右箱体1b之间形成轴向截面呈“凵”形的环形槽1c，环形槽1c包括正对设置的左侧壁和右侧壁，右侧壁为环形抵压面二1c1，左侧壁紧压在右轴承6外圈左端上，这样既可进一步定位右轴承6，又对右轴承6的安装进行导向，提高组装方便性。
实施例二
本实施例二同实施例一的结构及原理基本相同，不一样的地方在于：锁紧环7外壁的形状和尺寸均与箱体1左端口内壁匹配，且锁紧环7外壁和箱体1紧密配合固连。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
