Detailed introduction of RV series worm gear reducer

The RV series worm gear reducer is designed and manufactured according to the Q/MDl-2.000 technical quality standard.Based on the parameters of cylindrical worm gear according to the national standard GBl0085-88, the product absorbs the most advanced technology at home and abroad, and has a unique and novel "square box" shape structure. The box has a beautiful appearance and is made of high-quality aluminum alloy die-casting. .

Has the following advantages:
1. The mechanical structure is compact, the volume is light and the appearance is small and efficient;
2. Good heat exchange performance and fast heat dissipation;
3. Easy to install, flexible and light, superior performance, easy to maintain and repair;
4. Stable operation, low noise, and durable;
5. Strong applicability, high safety and reliability.
At present, it has been widely used in mechanical deceleration devices for production process equipment in various industries, such as: food, beverage, packaging, environmental protection, mining, metallurgy and other industries and fields of process equipment mechanical deceleration devices, which are well received by users and are currently modern The best choice for industrial equipment to achieve large torque, high speed ratio, low noise, and high stability mechanical deceleration transmission control device.

RV worm gear reducer is generally used for low-speed and high-torque transmission equipment. The power of electric motors, internal combustion engines or other high-speed running powers through the gears with fewer teeth on the input shaft of the reducer meshes with the large gears on the output shaft to achieve the purpose of deceleration , Ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.The reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the required number of revolutions and obtain a larger torque.

Input forms are divided into: hole input, shaft input, extended worm shaft type;
The output type is divided into: hole output, one-way shaft output, and two-way shaft output.



Working conditions
1. Smooth transmission, low vibration, impact and noise, large reduction ratio, wide versatility, and can be used with various mechanical equipment.
2. A large transmission ratio can be obtained with a single-stage transmission, and the structure is compact. Most types of reducers have better self-locking properties, and can save braking devices for mechanical equipment with braking requirements.
3. The meshing friction loss between the worm thread and the worm gear tooth surface is relatively large, so the transmission efficiency is lower than that of the gear, and it is easy to generate heat and high temperature.
4. Higher requirements for lubrication and cooling.
5. Good interoperability. Worm gears and worms are manufactured according to national standards, and standard parts such as bearings and oil seals are used.
6. The box body has basic type (the box body is a vertical or horizontal structure with a foot plate) and a universal type (the box body is a rectangular parallelepiped, with fixed screw holes on multiple sides, without a foot plate or another bottom Various structure types such as foot board)
7. There are two types of input shaft connection: basic type (single input shaft and double input shaft), with motor flange.
8. The position directions of the output and input shafts have the input shaft down and up; the output axis up and down; the input axis up and down.
9. Two or three reducers can be used to form a multi-stage reducer to obtain a great transmission ratio.

Please Note
1. The worm speed of the RV worm gear reducer cannot exceed 1500r/min.
2. The working environment temperature is -40℃-+40℃. When the working environment temperature is lower than 0℃, the lubricating oil must be heated to above 0℃ before starting. When the working environment temperature is higher than 40℃, cooling measures must be taken.
3. The shaft of the worm gear reducer can rotate forward and backward.Easy to use;
4. The motor matched with the NMRV worm gear reducer must be suitable for working in a low temperature environment;
5. The power of the motor must meet the torque requirement when starting at low temperature;
6. Before being put into use, the viscosity of the lubricating oil will be higher, so you should let the machine run without load before loading to avoid equipment failure;
7. When using the NMRV worm gear reducer for the first time, replace the lubricating oil after 150-400 hours of operation. The subsequent oil change cycle of the worm gear reducer is less than or equal to 4000 hours. 2 Regularly check the quantity and quality of the oil, keep enough lubricating oil, and replace the oil mixed with impurities or deterioration in time.

Installation matters
1. A variety of installation methods can be used according to actual requirements, and multiple surfaces can be installed;
2. The installation must be firm and reliable;
3. The working mechanism of the prime mover and reducer must be carefully aligned, and the error shall not be greater than the allowable compensation of the coupling used;
4. Rotate by hand after installation, it must be flexible and free from jamming.
