The industrial heavy duty planetary gear units (gearbox speed reducer) for vertically grinding in cement industry
Special design for thermal power plant with a set of 600MW which is used for grinding system.
The gearbox features compact structure, light weight, how noise, high ability of load and maintenance conveniently.
The base is welded with stand and stop-off strip in order to assure the intensity and rigidity.
The gearbox uses forced spray oil lubrication, achieving test of temperature, flux and pressure automatically. The pressure switch and the flux monitor can monitor the oil supply and feed back the pressure and flux signal which is switch quantity or analog quantity to primary control system.
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 5-6 (DIN).
