It is a new type of slewing ring for construction machinery and a heavy load type of spur gear slew drive

The material of the slewing ring and matching pinion inside the spur gear slewing drive is made of high-quality 42CrMo forgings, after tempering 229-269HB (Q+T) processing, the comprehensive mechanical properties are greatly improved to ensure customer equipment to provides strong support and has good operation.

All teeth are induction hardened and tooth surface hardness is 50HRC, tooth inside is soft, tooth surface quenching improves the single tooth load capacity and tooth wear resistance, the soft core ensures the toughness of the teeth under impact load, the teeth of the slewing ring and pinion are strong, durable and impact-resistant are the prerequisites for reliable operation and long life of the gear type slewing drive.

There will be vibrations when customer uses the spur gear slewing drive, in order to avoid loosening of the connecting bolts, Unique Transmission has applied thread fastening glue to each connecting bolt to ensure reliable operation of the gear type rotary reducer.All connecting bolts of the spur gear slewing drive adopt 8.8 grade high-strength galvanized bolts, which can ensure the connection strength and avoid equipment damage caused by bolt corrosion after long-term use.
