Abstract

一种带滚针轴承的摩托车发动机左后盖，在左后盖(1)上设置有让位孔(2)，让位孔(2)内穿过变档轴(3)，其中，所述让位孔(2)内安装有滚针轴承(4)，该滚针轴承(4)靠近让位孔的外端口，所述变档轴(3)穿过该滚针轴承(4)。本实用新型改变原变档轴与让位孔间隙配合为滚针轴承配合，滚针轴承不仅对变档轴起支撑作用，因而变档轴在变档时不直接与孔壁接触碰撞，不易变形，而且，由于滚针轴承为滚动摩擦，摩擦力较小，从而使发动机的变档更灵活。

Description

带滚针轴承的摩托车发动机左后盖
技术领域
本实用新型涉及一种发动机构件，特别是一种摩托车发动机上的左后盖。
背景技术
现有摩托车发动机的变档轴与发动机左后盖上的让位孔为间隙配合，如图2所示，变档轴让位孔在摩托车发动机左后盖上，让位孔内穿有变档轴，变档轴与让位孔为间隙配合。由于变档轴伸出让位孔的长度较长，因此在反复变档操作时，变档轴常与让位孔孔壁碰撞，极易受损伤，甚至变形。变档轴变形后与让位孔的摩擦力就增大，从而影响发动机变档的灵活性。
发明内容
本实用新型目的在于提供一种带滚针轴承的摩托车发动机左后盖，在保证变档轴转动灵活的基础上，解决变档轴在换挡过程中因与让位孔碰撞而造成的变形问题。
为了实现上述目的，本实用新型通过以下技术方案来达到，即一种带滚针轴承的摩托车发动机左后盖，在所述左后盖上设置有让位孔，让位孔内穿有变档轴，其关键在于，所述让位孔内安装有滚针轴承，该滚针轴承靠近让位孔的外端，所述变档轴穿过该滚针轴承。
本实用新型的显著效果是：改变原有变档轴与让位孔间隙配合为滚针轴承配合，由于有滚针轴承对变档轴起支撑作用，因此变档轴在变档时不直接与孔壁接触碰撞，不易变形，而且，由于滚针轴承为滚动摩擦，摩擦力较小，从而使发动机的变档更灵活。
附图说明
图1为本实用新型的主视图；
图2背景技术的主视图；
图3为左后盖的主视图；
图4为图3沿A-A处的视图。
具体实施方式
下面结合附图和实施例进一步说明本实用新型：
请参阅图1、图2、图3、图4，在左后盖1上设置有变档轴让位孔2，该让位孔2内穿有变档轴3，所述让位孔2内还安装有滚针轴承4，该滚针轴承4靠近让位孔的外端口；所述变档轴3穿过该滚针轴承4。滚针轴承是带圆柱滚子的滚子轴承，相对其直径，滚子既细又长，尽管具有较小的截面，但轴承仍具有较高的负荷承受能力。在让位孔2内安装滚针轴承4既可以对变档轴3起到支承作用，保证变档轴3在使用过程中不因碰撞、弯曲而变形，又可以减小变档轴与让位孔之间的摩擦，增加变档时的灵活性。在本实施例中采用型号为HK121610的滚针轴承。
