RXF Series Single Stage Helical Gearbox Design:
The RXF Series Single Stage Helical Gearbox with Flange Mounted is engineered with a compact, coaxial structure for maximum efficiency and flexibility. The housing, crafted from high-strength HT250 cast iron, ensures exceptional durability and resistance to cracking, making it ideal for flange flange-mounted helical gearbox for chemical industry applications. Gears are made from 20CrMnTi steel with a surface hardness of HRC58-62, optimized through advanced grinding and shape modification to minimize noise and maximize load capacity.
Equipped with premium bearings from SKF, C&U, and HRB and oil seals from SKF, NAK, and KSK, the gearbox ensures reliable sealing and minimal maintenance. The 40Cr steel shafts undergo multi-precision machining and rigorous dynamic/static balance tests to guarantee smooth, low-noise operation. Each unit is cleaned with diesel oil, painted, and pressurized to 2.5 kg to ensure zero oil leakage, with noise levels verified by a decibel meter. This makes the RXF Helical Gearbox with Cast Iron Housing perfect for demanding environments like cement plants and sugar plants.
