The invention discloses a disassembly-free self-lubricating rope supporting wheel, and relates to the technical field of coal conveying machines. The disassembly-free self-lubricating rope supporting wheel is connected with a wheel supporting shaft through a bearing. A lubricating grease channel is arranged inside the wheel supporting shaft. The two ends of the lubricating grease channel are connected with the bearing and a pressure distribution type oil injection cup respectively. The pressure distribution type oil injection cup comprises a cup body. The lower end of the cup body is connected with the lubricating grease channel. A filling opening of the cup body is arranged above the lubricating grease channel. A blocking piece is arranged at the filling opening. The blocking piece is a cuboid metal block. The upper end of the blocking piece is tightly attached to the filling opening. The lower end of the blocking piece is connected with the lower end of the cup body through an elastic component. According to the disassembly-free self-lubricating rope supporting wheel, the rope supporting wheel does not need to be disassembled in the lubricating grease adding process, the underground operation efficiency is improved, a steel ball can be recovered to be in the state of being tightly attached to the filling opening through the rebound effect of a spring, dust and other impurities can be prevented from entering the rope supporting wheel, and the service life of the rope supporting wheel is prolonged.
