The invention belongs to the field of machining of fuel rods, and particularly discloses a friction wheel feeding mechanism. The friction wheel feeding mechanism comprises a cylinder, a supporting plate, a motor, a motor support, a friction wheel, supporting wheels, a support, a torque limiter, a rotary shaft, a U-shaped frame, a belt wheel, a connecting bolt, a nut, a linear guide device and a bracket. The friction wheel is connected with the torque limiter. The lower end of the friction wheel directly makes contact with the upper end of a fuel rod. The lower end of the fuel rod directly makes contact with the supporting wheels. The friction wheel drives the fuel rod to move in the left-right direction through friction force. After the fuel rod is moved to a designated station, the friction wheel can be stuck through the torque limiter which is adjusted in advance to make the rotary shaft to idle. The friction wheel feeding mechanism can achieve non-abrasion machining of the fuel rod.
