Parallel shaft reducers are F-series reducers among the four major series of hardened gear R, FS, and K reducers. They adopt the modular design principle of unit structure, which greatly reduces the types of parts and inventory quantities and also significantly shortens the delivery cycle. The high-rigidity cast iron casing with ribs and the gears are made of alloy steel. The surfaces of the gears are treated by carburizing, quenching and hardening, and are finished by gear grinding. They have smooth transmission, low noise, high load-carrying capacity, low temperature rise and long service life.
Parallel shaft reducers consist of two-stage or three-stage helical gears, which is related to the reduction ratio, and are installed in the same casing. There are a total of 11 specifications of parallel shaft helical gear reducers, with the torque range from 3 to 22,500 Nm and the maximum output power of the motor being 200 kW.
The transmission ratio range of parallel shaft reducers is from i = 3.77 to i = 31,434 with fine gradation. It can achieve extremely low output speeds (multi-stage reducers with additional helical gear input stages).
Parallel shaft reducers are widely used in fields such as light industry, food, beer and beverage, chemical industry, escalators, automated warehousing equipment, construction, machinery, iron and steel metallurgy, papermaking, wood-based panel machinery, automobile manufacturing, tobacco machinery, water conservancy, printing and packaging, pharmaceuticals, textiles, building materials, logistics, feed machinery, and environmental protection.
