Product Description
NMRV worm gear motor is a specific gear composition in which a screw (worm) meshes with a gear/wheel similar to a spur gear. The set-up allows the user to determine rotational speed and also allows for higher torque to be transmitted. This mechanism can be found in heavy machinery. The NMRV worm gear motor is made of high-quality aluminum alloy, with the features of light weight and not easy to rust. Due to the NMRV series running smoothly and low in noise, it is suitable to long time work in bad environment.
Main Materials
Housing: die-casting aluminum alloy (frame size: 025 to 090); cast iron (frame size: 110 to 150).
Worm: 20Cr, carbonize & quencher heat treatment make the hardness of gear’s surface up to 56-62HRC, retain carburation layer’s thickness between 0.3 and 0.5mm after precise grinding.
Worm wheel: wearable stannum bronze alloy.
Surface Coating:
Aluminum alloy shell: First of all, the shell through surface pellet blasting treatment, and then through special anti-corrosion treatment, to maintain the sense of silver white metal, and through the corrosion treatment of gasoline, xylene and other organic solvents. After phosphating treatment, spray RAL5010 blue or white paint in the shell.
Cast iron shell: spray red anti-rust paint, then spray blue RAL5010 paint in the shell.
Frequently Asked Questions
What are the main advantages of NMRV worm gear motors?
NMRV worm gear motors offer high torque transmission, smooth operation, low noise levels, and a compact design that saves mounting space. They are also lightweight and resistant to rust.
What materials are used in the construction of these motors?
The housing is made of die-casting aluminum alloy or cast iron depending on the size. The worm is constructed from 20Cr with heat treatment, and the worm wheel is made of wearable stannum bronze alloy.
Is the NMRV series suitable for harsh environments?
Yes, due to its high-quality aluminum alloy construction and special anti-corrosion surface treatments, it is designed for long-term operation even in bad environments.
What is the hardness of the worm gear surface?
Through carbonizing and quenching heat treatment, the surface hardness of the gear reaches between 56-62HRC, ensuring high mechanical strength and durability.
How is the surface of the aluminum alloy shell treated?
The shell undergoes pellet blasting, special anti-corrosion treatment, and phosphating before being sprayed with RAL5010 blue or white paint to ensure resistance to organic solvents.
Can this motor be easily integrated with other machinery?
Absolutely. The NMRV worm reducer is designed for omni-bearing installation, making it highly versatile and easy to connect with various types of industrial machinery.
