Running-in machine for multi-sleeve bearing

Disclosed is a multiple bearing running-in machine. An electromotor and a running-in head fixing stand are arranged on a frame. A running-in head is arranged on the running-in head fixing stand, and a driven cog belt wheel is arranged on the running-in head. A drive cog belt wheel is arranged on an output shaft of the electromotor, and is connected with the driven cog belt wheel through a synchronous cog belt. A filter connected with the running-in head through a pipe is arranged at the left side of the frame, and a transducer connected with the electromotor through a lead is arranged at the right side of the frame. The multiple bearing running-in machine adopts the transducer to control the rotation speed of the electromotor, and the drive cog belt wheel, the synchronous cog belt and the driven cog belt wheel to form a transmission shaft, thus improving running-in precision of the bearings. The bearing running-in machine can run in 10 bearings, the running-in head is moveably connected on the running-in head
