Problems solved by technology
[0002] Bearings, collector rings, and snap rings need to be press-fitted on both sides of the upper gear of the high-speed railway wheel set. The existing technology is to use a single-arm press, a double-column press or a four-column press to complete the equipment. The parts can only be press-fitted on the press, which is time-consuming and labor-intensive, and the cost of tall equipment is high
