Slewing bearing lubricating grease filling device and method and excavator
The invention discloses a slewing bearing lubricating grease filling device and method and an excavator. The slewing bearing lubricating grease filling device comprises N pressure sensors, a lubricating block, M lubricating pipes, a pump and a controller. Each pressure sensor is communicated with a roller path on the slewing bearing, at least one pressure sensor is arranged between adjacent filling ports on the slewing bearing, and each filling port is communicated with the roller path; one end of the lubricating block is connected with the pump, the other end of the lubricating block is connected with one end of each lubricating pipe, the other end of each lubricating pipe is communicated with a corresponding filling hole in the revolving platform, and each filling hole in the revolving platform is communicated with a corresponding filling port in the slewing bearing; the input end of the controller is connected with the output ends of the pressure sensors, the output end of the controller is connected with the pump, and the controller controls the running state of the pump based on pressure signals output by the pressure sensors and a preset lubricating grease filling strategy. The lubricating grease filling device can ensure proper amount of lubricating grease filling of the slewing bearing, and waste caused by excessive overflow or abnormal wear of the slewing bearing caused by insufficient filling can be avoided.
本发明公开了一种回转支承润滑脂加注装置、方法及挖掘机，包括N个压力传感器、润滑块、M个润滑管、泵和控制器；各压力传感器与回转支承上的滚道相连通，回转支承上的相邻加注口之间至少设置一个压力传感器，各加注口与滚道相连通；润滑块的一端与泵相连，另一端与各润滑管的一端相连，各润滑管的另一端与回转平台上对应的加注孔相连通，回转平台上的各加注孔与回转支承上对应的加注口相连通；控制器的输入端分别与各压力传感器的输出端相连，其输出端与泵相连，基于各压力传感器输出的压力信号，以及预设的润滑脂加注策略，控制泵的运行状态。本发明能够保证回转支承润滑脂加注适量，不会出现多量溢出造成浪费，或加注不足造成回转支承异常磨损。
