Rossi R and MR series helical gearboxes (also known as Rossi or Rossi gearboxes) include models with three-sided (sizes 32 to 81) or two-sided (sizes 100 to 250) coated end mounts and B14 or B5 flanges. They are in two ways.
The optimal design of these gearboxes allows for good solutions in shaft installation. Among the other advantages of the Rossi helical gearbox, we can mention the optimization and compression of the dimensions in accordance with the standards. The cast iron shell of the Russian helical gearbox is made completely uniform, accurate and strong.
The proper internal space between the gears and the shell allows the oil capacity to increase, the oil pollution to decrease, the life of the worm wheel and bearings to increase, the heat to decrease, and the possibility of installing high power motors on it.
These helical gearboxes produced by Rossi Gearbox Company are used in various industries and devices such as conveyors, mixers, elevators, fillers, mills and crushers, concrete mixers, bakery machines and many industrial, non-industrial and agricultural sectors.
In order to achieve optimal performance from 6 to 18%, higher load capacity, greater reliability and greater wear resistance of the helical gears of the Rossi gearbox and worm gear, A04 reduction gears and a geared motor are made of nickel bronze with controlled phosphorus content. has been
