Abstract

一种新型的转动轴，由阶梯轴、衬套、轴承套、外套和轴承依次套合而成。其中衬套与轴承套通过暗锁固定联结之，轴承通过圆钉键分别与阶梯轴和轴承套配合，外套、轴承套和衬套上设有注油孔，阶梯轴、外套和轴承外侧密封垫围成一个贮油空间。本转动轴的优点是轴承转动件不易磨损、不必定期保养；装、拆极为方便，轴承的松紧不必校正。

Description

新型转动轴
本实用新型涉及一种转动轴，特别是一种摩擦阻力小，各部件处于动配合状态下的新型转动轴。
现有的电机、风机、车轮......等转动机构主要由轴、轴承。轴承套、外套等部件静配合组成。这种静配合组装方法造成轴承套内的轴承不平衡。并且它又采用固体润滑剂。因此静配合造成了轴承磨擦阻力增大；各部件易损坏。
本实用新型的目的是提供一种在机械领域中使用的新型转动轴。
本实用新型是按如下的方式来实现的：
新型转动轴包括阶梯轴、轴承、衬套、轴承套、外套、外套锁母及密封垫。所述的阶梯轴、衬套、轴承套、外套和轴承依次套合，其中：衬套的长度应大于阶梯轴中部凸出部分的长度；阶梯轴的外径应小于轴承的内径；轴承套的内径应大于轴承的外径。衬套和轴承套通过暗销固定联结之。外套、轴承套和衬套上，设有注油孔。轴承位于衬套两端，且套合于轴承套内、轴承套的长度应大于衬套长度和两个轴承厚度之和，轴承上设有内圈键槽和外圈键槽、轴承套上设有园钉键。该园钉键与与轴承外圈键槽相吻合，阶梯轴上也设有园钉键。该园钉键与轴承内圈键槽相吻合，轴承的外侧设有密封垫。密封垫的外侧是外套锁母。该锁母与外套通过螺口固定联接之。密封垫与阶梯轴和外套所围成的空间构成贮油装置。通过外套上的注油孔注入润滑油。
本实用新型的优点是：
1、轴承转动件不易磨损；不必定期保养；
2、不必去专业部门进行维修，省开支；
3、装、拆极为简单，轴承松和紧不必校正；
下面结合附图对本实用新型做进一步说明：
图1为本实用新型结构图。
图2为轴承的纵向剖面图。
图中：1-阶梯轴，2-外套锁母，3-密封垫，4-轴承，5-衬套，6-轴承套，7-外套，8-轴上的园钉键，9-轴承套上的园钉键，10-暗销，11-轴承外圈键槽，12-轴承内圈键槽，13-注油孔。
如图1所示，阶梯轴、衬套5、轴承套6、外套7、轴承4依次套合，衬套5和轴承套6通过暗销10固定联结之，外套7轴承套6衬套5上设有注油孔13，轴承4位于衬套5两端，且套合于轴承套6内。轴承上设有内圈键槽12和外圈键槽11，阶梯轴上设有园钉键8，轴承套上设有园钉键9，轴承内圈通过园钉键8与阶梯轴配合，轴承外圈通园钉键9与轴承套配合。轴承4的外侧设有密封垫3，密封垫3的外侧是外套螺母2，外套螺母2通过外套上的螺口与外套7固定联结之。所述衬套的长度应大于阶梯轴中间凸起部分的长度，所大于部分以0.3-0.5mm为宜；阶梯轴的外径应小于轴承的内径；轴承套的内径应大于轴承的外径；轴承套的长度应大于衬套长度和两个轴承厚度之和，所大于部分以0.3-0.5mm为宜。
