　　The NMRW reducer itself can be combined into a two-stage conjoined reducer. DRW's transmission ratio is the product of NMRW and two-stage NMRW transmission ratio, which can extend the transmission ratio to the range of 1:300--3200.


















　　DRW is not a simple combination of two NMRW, reasonable combination should make the two reducer to achieve consistent working conditions, so the size of the two-stage reducer frame is larger than the size of the reducer frame.
　　Zhongyan purple light reducer structural characteristics:
　　1. Aluminum alloy casting box, adapt to a full range of installation configuration
　　2. Sufficient cooling ribs, so that the body has excellent heat conduction performance;
　　3. From 025--150, there are 10 kinds of base specifications; the transmission power range is from 60W--15KW;
　　4. Large speed ratio range, each single frame has 12 reduction ratios from 5:1 to 100:1;
　　5. Precision grinding hard tooth surface drive worm, high efficiency, large output torque;
　　6. Low noise smooth 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 extend the transmission ratio of RW gear units to:i=5--32000.
　　9. Shell: aluminum alloy (base:025--090), cast iron (base:110--150);
　　10. Worm: 20Cr steel, carbonitriding treatment (after fine grinding, keep the hardness of tooth surface HRC60, hard layer thickness> 0.5mm);
　　11. Worm gear: specially formulated wear-resistant nickel bronze.
　　12. paint
　　--Aluminum alloy:
　　① After shot blasting treatment, special anti-corrosion treatment (keep silver alloy color, and resist the corrosion of gasoline, xylene and other organic solvents);
　　② After phosphating treatment, spray RAL5010 blue baking paint;
　　- Cast iron: painted RAL5010 blue baking paint.
　　13. workpiece ratio
　　Efficiency is an important index of reducer, which depends on the design and manufacture of worm gear transmission pair and friction condition. Since the speed reducer has different friction characteristics in the running state and in the static state, the efficiency of the speed reducer has dynamic efficiency and static efficiency:
　　① Dynamic efficiencyη d: transmission efficiency of the reducer under operating conditions (dynamic friction);
　　Static efficiencyη S: transmission efficiency of the reducer at rest (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, d S.
　　14. reversibility of transmission
　　In the reducer output end (worm wheel) torque applied to drive the input end (worm) transmission process is the reducer reverse transmission. The characteristics of the reducer in reverse transmission is the reversibility of the worm reducer. Attention must be paid to this characteristic of the selected reducer during use.
　　The transmission reversibility of the reducer is related to the efficiency of the deceleration, corresponding to the static efficiency S and the dynamic efficiency d. The transmission reversible characteristics of the reducer are described as follows:
　　ηS 0.5: Static irreversible. That is, when the reducer is at rest, it cannot drive the input worm by applying torque to the output worm wheel, and the reverse transmission is self-locking.
　　ηS=0.5-0.55: Low static reversible. That is, when the reducer is at rest, it can drive the input worm by applying torque to the output worm wheel, and the self-locking is not strong.
　　ηS 0.5: Static reversible. That is, when the reducer is in a static state, it can drive the input worm by applying torque to the output worm wheel, and cannot self-lock.
　　ηd 0.5: Dynamics irreversible. That is, the reducer in the transmission process, the input shaft from the power, the output shaft can immediately stop.
　　ηd 0.5-0.6: Low dynamic reversible. That is, the reducer in the transmission process, the input shaft from the power, the output shaft can not immediately reliable stop.
　　ηd 0.6: Dynamically reversible. That is, the reducer in the transmission process. When the input shaft is disconnected from power, the output shaft cannot stop by self-locking.
