Structural characteristics of RV worm gear reducer:
1. High-quality aluminum alloy casting box, suitable for all-round universal installation and configuration;
2. Sufficient cooling ribs, so that the body has excellent thermal conductivity;
3. There are 10 chassis specifications from 025 to 150; the transmission power range is from 60W to 15KW;
4. The speed ratio range is large, and each single frame has 12 reduction ratios from 5:1 to 100:1;
5.Precision grinding and processing of hard tooth surface transmission worm, high efficiency and large output torque;
6. Low noise and stable operation, suitable for long-term continuous work in harsh environments;
7. Light weight and high mechanical strength;
8. The modular combination enables PCRW and DRW to expand the transmission ratio of the RW reducer to: i=5--32000.
Main materials of worm gear reducer:
1. RV reducer housing: aluminum alloy (frame: 025--090), cast iron (frame: 110--150);
2. Worm: 20Cr steel, carbon and nitriding treatment (maintain the tooth surface hardness HRC60 after fine grinding, the thickness of the hard layer>0.5mm);
3. Worm gear: specially formulated wear-resistant nickel bronze.
Paint for worm gear reducer:
1. Aluminum alloy:
1) After pill treatment, special anti-corrosion treatment (maintain the color of silver white alloy, and resist the corrosion of gasoline, etc.);
2) After phosphating treatment, spray RAL5010 blue baking paint;
2. Cast iron: sprayed with RAL5010 blue baking paint.

Efficiency is an important indicator of the reducer, which depends on the design and manufacture of the worm gear transmission pair and the friction condition. Since the reducer has different friction characteristics in the running state and in the stationary state, the efficiency of the reducer has dynamic efficiency and static efficiency correspondingly:
1. Dynamic efficiency ηd: the transmission efficiency of the reducer under operating conditions (dynamic friction);
2. Static efficiency ηS: the transmission efficiency of the reducer in the stopped state (static friction);
Since the static friction coefficient of the friction pair is greater than the dynamic friction coefficient, the dynamic efficiency of the reducer is greater than the static efficiency, that is, ηd>ηS.
RV reducer structure composition
1. The basic structure of RV reducer is mainly composed of transmission parts worm gear, shaft, bearing, box and accessories.
2. It can be divided into three basic structural parts: box body, worm gear, bearing and shaft combination.
3. The box is the base of all the accessories in the RV series reducer. It is an important accessory that supports the fixed shaft system components, ensures the correct relative position of the transmission accessories and supports the load acting on the RV reducer.
4. The main function of the worm gear is to transmit the motion and power between the two interleaved shafts, and the main function of the bearing and the shaft is to transmit power, operate and improve efficiency.
