The utility model discloses a sliding bearing, bearing seat, bearing lubrication, including rod and the connecting sleeve; the bearing seat is arranged at the bottom of the inner hole of the coupling sleeve within two of the bearing is mounted on the bearing seat, the front end of the lubricating rod and the bearing seal fixed connection to the lubricating grease is pressed into the bush with the plane. By applying the rigid support of the two bearing bushes, the sliding bearings which are provided by the utility model greatly increase the contact area, reduce the specific pressure, keep the concentric rotation of the connecting shaft, and form stable oil film under the condition that the grease is not missing, thereby greatly reducing the wear. The front end of the lubricating rod is connected with the seal of the axle bush, and the grease is directly pressed into the matching surface of the axle bush, so the grease will not be lost, and the lubrication effect is improved. At the same time, the wear of sliding friction pair is very small, and the coupling shaft and axle bush need not be changed frequently, which greatly reduces the cost of spare parts.

一种滑动轴承
本技术涉及轴承
,更具体地说,涉及一种滑动轴承。
技术介绍
垂直输送机其螺旋转速设计时通常选择在350-500rpm之间,螺旋的总长度在10-30m,质量由数百千克至数千千克,因而仅靠两端支承实现高速平稳旋转十分困难,因此必须沿螺旋的轴向每隔4-5m设一处中间支承。现有技术中有采用滑动三瓦组合轴承进行支承。滑动三瓦组合轴承采用三个棒瓦支承,接触面积小,比压大,磨损快;棒瓦是弹性支承,联接轴运转时轴心不固定,承压面是线接触,比压非常大,润滑脂形成的油膜也容易被破坏,因此磨损很快;两侧圆弧面经常翻边,需要拆下检修,否则润滑脂不能从两侧油道压出,摩擦面得不到良好润滑降温,联接轴、棒瓦就会剧烈磨损;棒瓦在棒瓦套内高频滑动,三个棒瓦导向面都需要润滑,润滑脂消耗量巨大;联接轴、棒瓦磨损后需重新调整弹簧支承力,标准无法量化,导致机修人员经验差异、负责任程度不同都会影响设备运行状况;联接轴、棒瓦磨损很快,如不及时更换调整,联接轴就会把棒瓦座磨损,同时会导致螺旋叶片擦壳,损失更大;联接轴转动时轴心不固定,高频振动,无法有效密封,只能加大润滑脂供脂量。综上所述,如何有效地解决滑动轴承磨损快、润滑脂消耗量大等问题,是目前本领域技术人员急需解决的问题。
