Aluminum alloy worm gear reducer called RV reducer

RV gear is a new kind of reducer, also called the NMRV reducer, perhaps called alloy reducer. "NMRV" is a general term, it points to the mean aluminum shell reducer, the aluminum shell is called "NMRV speed reducer". RV speed reducer has the advantages of light weight, superior strength, exquisite appearance, high heat dissipation function, long service life, no noise and the expertise of action, and the motor connection convenience simple. Widely used in packaging, printing, textile, rubber, wire and cable and automation equipment category.
1, RV reducer application environment is lower than -30 DEG C may be higher than the temperature of 60-30 DEG C, oil seal is necessary to replace the special material;
Motor 2, and RV gear matching necessary for working in low temperature environment, and the power of the motor is necessary to satisfy in the cold starting torque requirements;
3, prepare to put in before using lubricating oil viscosity is high, should let the machine no-load test of homework and loading, prevent causing equipment failure;
4, for the first time using RV reducer, replacement of lubricating oil in its operation after 150-400 hours, the future oil worm reducer period is less than or equal to 4000 hours. Check the oil quantity and quality, save meet the lubricating oil, mix impurities or transformation of the oil replacement in a timely manner. Operating coefficient of NMRV worm gear reducer is dependent on the actual operating environment, when the service coefficient to choose the appropriate necessary thinking at the output of the nature of the load, daily work time and start frequency so element.
The majority of worm gear box structure is the use of gear axis horizontal partition to install, adjust, easy worm gear shaft. The first-order natural frequency, NMRV reducer cause resonance, therefore, when the planning and selection of RV reducer and operation speed must, should as far as possible to increase the list head transmission ratio, decreased second stage transmission ratio, in order to prevent resonance stiffness encourage result. Should as far as possible to increase the list head transmission ratio, decreased second stage transmission ratio. The first natural frequency of RV reducer mainly by the double crank shaft stiffness change resolution, therefore, RV reducer function problem is to determine a reasonable structure and materials of double crank shaft, the progress of its changing stiffness.
Commercial clarification: RV series worm gear reducer according to the quality standard Q/MD1-2000 programming skills of making.
According to the above commodity in accordance with the national standard GB10085-88 worm wheel parameter foundation, worm gear reducer at home and abroad the most advanced technology, a unique new kind of "square box" outside the structure, box appearance, made of high quality aluminum alloy die casting and become.
1 Mechanical compact structure, small volume, high light;
The 2 heat exchange function is good, fast heat dissipation;
3 the equipment simple and sensitive function superior, nimble, easy to maintain;
4 big transmission ratio, large torque, high overload can accept;
5 a smooth running, low noise, durable;
6 applicability, safety and reliability.
RV series worm gear reducer is currently widely used in metallurgy, mining, transportation, water conservancy, chemical industry, food, beverage, textile, tobacco, packaging, environmental protection and many other professional and technical category of equipment mechanical reduction equipment, well received by users, is the best selection of the modern industrial equipment to complete the large ratio of low noise and high stability of mechanical deceleration driving and control device.
