The cross head bearing is a key component of a cross shaft bracket type universal joint coupling and is also a vulnerable component.
If a large impact load is encountered in the transmission process of the cross-shaft type universal joint coupler, or when the high load swings, unbalanced force or moment can be generated, so that the rolling bodies of the cross-shaft type universal joint coupler are subjected to eccentric wear between the shaft sleeve and the shaft neck, the eccentric wear is deepened continuously along with the wear, and when the wear reaches a certain depth, the rolling bodies can finally fall off, so that the cross-shaft type universal joint coupler is invalid, and the safe work and the service life of the cross-shaft type universal joint coupler are affected.
Aiming at the repairing problem of the worn cross head bearing, a repair welding process is usually adopted at present, the worn parts of the shaft neck and the shaft sleeve of the cross head bearing are subjected to surfacing, then the welded parts are subjected to turning or grinding in a machining mode, finally the original dimensions and the original precision requirements are restored, and finally the rolling body spare parts are assembled. However, the coating and the base material are mechanically combined, so that the surface coating is easy to fall off under a large load, and the repairing process requirement cannot be well met. The cross-head universal joint coupling used in the current domestic steel mill mostly belongs to imported parts, the manufacturing cost is relatively high, and the production practice urgently needs a cross-head bearing repairing process which is high in adaptability, convenient to operate and low in cost, so that the service life of the repaired rear half coupling is prolonged, and the production cost of enterprises is reduced.
