Abstract

本实用新型公开了一种风电齿轮箱行星轮轴承定位结构，行星轴(3)一端固定在行星架(1)侧壁上，行星轴(3)另一端端部直径略大形成台阶面，台阶面与行星架(1)侧壁对两个轴承(4)轴向定位；行星轴(3)为中空结构，行星轴(3)内设有螺栓(2)，螺栓(2)穿过行星轴(3)与行星架(1)侧壁连接，对两个轴承(4)进行轴向预紧。本实用新型由于只需通过控制定距环的宽度尺寸公差即可完成对轴承的轴向定位，对行星架两侧臂之间的轴向尺寸无公差要求，使加工更加简单；且通过螺栓对行星轴承进行轴向预紧，减少了目前行星轴承定位结构中的调整垫零件，操作更方便。

Description

风电齿轮箱行星轮轴承定位结构
技术领域
本实用新型涉及一种风电齿轮箱行星轮轴承支撑装置，尤其涉及采用螺栓轴向预紧的风电齿轮箱行星轮轴承定位结构。
背景技术
目前行星齿轮的轴承多采用的锥滚子轴承支撑方式，在轴承安装过程中轴承定位方式不便于控制，既要通过对两个配对轴承之间的隔圈宽度尺寸公差进行控制，又要对行星架两侧臂之间的轴向尺寸公差严格要求，对加工造成难度。此外，轴承预紧通过对轴承与行星架之间的调整垫进行调整，操作不便。
实用新型内容
本实用新型所要解决的技术问题在于提供一种轴向定位容易，预紧易操作的风电齿轮箱行星轮轴承定位结构。
本实用新型的技术方案如下：一种风电齿轮箱行星轮轴承定位结构，行星架上固定有行星轴，该行星轴上套有行星齿轮，所述行星齿轮经两个轴承支承在行星轴上，所述两个轴承之间由定距环隔开，其关键在于：所述行星轴一端固定在行星架侧壁上，行星轴另一端端部直径略大形成台阶面，该台阶面与行星架侧壁对两个轴承轴向定位；所述行星轴为中空结构，该行星轴内设有螺栓，该螺栓穿过行星轴与行星架侧壁连接，对两个轴承进行轴向预紧。利用螺栓的预紧来调整行星架侧壁与行星轴另一端端部台阶面之间的距离，来对两个轴承及定距环轴向定位。加工零部件过程中不需要复杂严格的公差计算。
上述中空的行星轴侧壁上开有油孔，该油孔与定距环上进油孔相通。相通对行星轴承进行飞溅润滑。
上述轴承为圆锥滚子轴承。
有益效果：本实用新型由于只需通过控制定距环的宽度尺寸公差即可完成对轴承的轴向定位，对行星架两侧臂之间的轴向尺寸无公差要求，使加工更加简单；且通过螺栓对行星轴承进行轴向预紧，减少了目前行星轴承定位结构中的调整垫零件，操作更方便。
附图说明
图1为本实用新型结构示意图。
具体实施方式
下面结合附图和实施例对本实用新型作进一步说明：
如图1所示，本实用新型一种风电齿轮箱行星轮轴承定位结构，行星架1上固定有行星轴3，该行星轴3上套有行星齿轮6，所述行星齿轮6经两个轴承4支承在行星轴3上，轴承4为圆锥滚子轴承。两个轴承4之间由定距环5隔开，所述行星轴3左端固定在行星架1侧壁上，行星轴3右端端部直径略大形成台阶面，该台阶面与行星架1左端侧壁对两个轴承4轴向定位；所述行星轴3为中空结构，行星轴3为右端开口的筒状，所述中空的行星轴3侧壁上开有油孔，该油孔与定距环5上进油孔相通。该行星轴3内设有螺栓2，该螺栓2穿过行星轴3左端的的端面与行星架1侧壁连接，对两个轴承4进行轴向预紧。
尽管以上结合附图对本实用新型的优选实施例进行了描述，但本实用新型不限于上述具体实施方式，上述具体实施方式仅仅是示意性的而不是限定性的，本领域的普通技术人员在本实用新型的启示下，在不违背本实用新型宗旨及权利要求的前提下，可以作出多种类似的表示，这样的变换均落入本实用新型的保护范围之内。
