Description

推力圆柱滚子轴承
技术领域
 本实用新型涉及推力圆柱滚子轴承，属于轴承制造领域。
背景技术
推力圆柱滚子轴承用于承受较重的轴向载荷，多用于钻机等重型工程机械上，推力圆柱滚子轴承由轴圈、座圈、保持架和滚子的组件组成，三件都可分离。为了承受较重的载荷，推力圆柱滚子轴承的滚动体尺寸很大，长度很长，使得运转过程中滚子两端的线速度差别加大，造成磨损，影响轴承运转，降低轴承的使用寿命。普通推力圆柱滚子轴承的保持架无引导，造成保持架轴向窜动，令轴承运转不平稳，润滑不畅，摩擦较大。
发明内容
鉴于已有技术存在的缺陷，本实用新型的目的是要提供一种运转平稳、润滑充分、摩擦小，从而能够提高轴承的使用寿命的推力圆柱滚子轴承。
为实现上述目的，本实用新型所采用的技术解决方案是：推力圆柱滚子轴承，两列滚子并排放在保持架座内，并与保持架盖配合安装，用弹性圆柱销锁紧；其特征在于：滚子与保持架座、保持架盖组成的一体件置于座圈与轴圈之间，保持架座、保持架盖组成的一体件与座圈引导表面处，设计半圆形润滑油槽，充分润滑，使引导面处形成充分的润滑油膜。
采用上述方案后，与现有技术相比具有以下有益效果：保持架座、保持架盖组成的一体件与座圈引导表面处，设计半圆形润滑油槽，充分润滑，使引导面处形成充分的润滑油膜，减小摩擦，提高了轴承寿命。
附图说明
图1是推力圆柱滚子轴承的结构简图。
图1中的附图标记如下：1、座圈，2、轴圈，3、滚子，4、保持架座，5、保持架盖，6、弹性圆柱销。
具体实施方式
   为深入了解推力圆柱滚子轴承，结合图1说明如下：
两列滚子3并排放在保持架座4内，并与保持架盖5配合安装，用弹性圆柱销6锁紧；滚子3与保持架座4、保持架盖5组成的一体件置于座圈1与轴圈2之间。保持架座4、保持架盖5与座圈1引导表面处，设计半圆形润滑油槽，充分润滑，使引导面处形成充分的润滑油膜。
