Schwerlast-Großgetrieben für Walzwerk vertic

Special design for driving rolling mill in rolling factory which manufactures wire and rod. The two output shafts join the rolling with universal coupling, driving the roller of the rolling mill. The output shaft has two structures: one is hollow, the other is solid. The gearbox features compact structure, light weight, small volume, high load, low noise and vibration. The gearbox can achieve test of temperature and vibration automatically. The gear is manufactured by high-quality alloy steel with carburizing and quenching. The tooth surface hardness is HRC57+4. The gear is modified with serrated form. The class of precision is grade 5-6 (DIN). The commonly used specification is designed in series and the gear in gearbox is designed in modularization. So, the amount of spare part is few. The case’s structural style has horizontal and vertical split structure, which is manufactured conveniently and fine appearance. The case is welded manufactured which is annealed after welding. The case will be dealt with aging treatment in order to eliminate residual stress. So, the case deforms hardly. The gearbox uses forced spray oil lubrication, the lubrication pipelines is distributed in or out of the gearbox, which can lubricate the gear and bearing sufficiently. The oil inlet and the oil discharge mouth are mounted on the gearbox. The pressure switch, the flux monitor and the cut-off valve are mounted near the oil inlet. The pressure switch and flux signal which is switch quantity or analog quantity to primary control system.
