The 1.RV worm reducer models:
RV25, RV30, RV40, RV50, RV63, RV75, RV90, RV110, RV130
ηS> 0.5: Static reversible. I.e. reducer in the stationary state, can be applied by the worm wheel to the output torque driven input worm can not be self-locking.
ηd <0.5: Power irreversible. Reducer in the transmission process, disengaged from the input shaft power output shaft that is able to immediately stop.
ηd <0.5-0.6: low power reversible. Reducer in the transmission process, input shaft disengage the power output shaft can not be immediate stop.
ηd> 0.6: dynamic reversible. Reducer in the transmission process. Disengage the power input shaft, the output shaft can not be self-locking stop the main material
- Housing: aluminum alloy (base 025 - 090), cast iron (stand 110 - 150);
- Worm: 20Cr steel, carbon, nitrogen permeation process (keep the tooth surface hardness HRC60, after fine grinding hard layer thickness> 0.5mm);
- Worm: specially formulated wear resistant nickel bronze.
- Aluminum:
① after the blasting treatment, the special anti-corrosion treatment (holding Argent aggregate golden sense, and gasoline resistance, the corrosion of the organic solvent, xylene, etc.);
② phosphating, spray RAL5010 blue baking paint;
- Cast iron: spraying RAL5010 blue baking paint.
Transmission reversible
Applied torque driven input (worm) in the the reducer output of (worm) transfer process is the reverse drive gearhead. Reducer in reverse drive performance characteristics of the worm reducer drive reversible. Must pay attention to in the course of this characteristic of the selected gearhead.
Reducer drive reversible and the efficiency of the deceleration corresponds to the static efficiency ηS and dynamic efficiency ηd. Reducer pass drive reversible characteristics are described as follows:
ηS <0.5: Static irreversible. I.e. the reducer in the stationary state, can not be applied to the output worm the torque driven input self-locking worm, reverse drive.
ηS = 0.5-0.55: low static reversible. Reducer in the stationary state, can worm input torque is applied to the output worm gear driven, self-locking is not strong. Worm reducer
Efficiency
Efficiency reducer important indicators, depending on the design and manufacture as well as friction condition of worm gear transmission Vice. As the gear unit having different friction characteristics under the operating state and in the stationary state, and therefore the efficiency of the gear unit corresponding dynamic efficiency and static efficiency:
① dynamic efficiency ηd: reducer transfer efficiency in operating condition (dynamic friction);
② static efficiency ηS: reducer in a stopped state (static friction), the transfer efficiency;
Greater than the dynamic coefficient of friction due to the static coefficient of friction of the friction pair, the reducer dynamic efficiency is greater than the static efficiency, that ηd> ηS.
