RV cast iron worm gear reducer is a product derived from RV aluminum housing reducer.Using the principle of planetary gear transmission, through the cylindrical needle roller moves eccentrically with the RV gear in the inner ring of the housing.Make multiple sets of RV gear teeth engage with the needle roller at the same time, decelerate the rotation number of the motor to the required rotation number, and output a larger torque. RV cast iron worm gear reducer shell made of cast iron material, with high strength, stiffness and impact resistance. The shell of the RV aluminum reducer is aluminum alloy material, low density, light weight, and corrosion resistance.
In metallurgy, mining and other heavy industry, the equipment operating conditions are complex, large load, more impact, RV cast iron worm gear reducer is more suitable, its heavy appearance, to deal with the equipment operating conditions are complex, large load, impact of metallurgy, mining and other heavy industry is more suitable.
Its model is: NMRV50, NMRV63, NMRV75, NMRV90, NMRV110, NMRV130, NMRV150 are available for customers to choose from.
The processing process of cast iron reducer may be more complex, and the overall cost will increase compared with that of aluminum reducer.
Cast iron reducer due to the heavy, installation needs more manpower and equipment assistance, but its installation surface is usually more flat, better rigid, to ensure installation accuracy.
