    Detailed description:

    ●RV worm gear reducer model:

    RV25. RV30. RV40. RV50, RV63. RV75. RV90. RV110. RV130

    nS>0.5: Static reversible. That is, when the speed reducer is in a stationary state, the input worm can be self-locked by applying a torque to the output worm wheel.

    Nd<0.5: The power is irreversible. That is, the output shaft can be stopped immediately when the input shaft is disengaged during the transmission.

    Nd<0. 5-0.6 Low power reversible. That is, the output shaft cannot be reliably stopped immediately when the input shaft is disengaged during the transmission.

    Nd>0.6 power reversible. That is, the reducer is in the process of transmission. When the input shaft is disengaged, the output shaft cannot be self-locking to stop the main material.

    Housing: aluminum alloy (frame: 025--090), cast iron (frame: 10--150);

    Worm: 20Ct steel, carbon-ammonia treatment (maintaining tooth surface hardness HRC60 after fine grinding, hard layer thickness >0.5mm);

    Worm gear: specially formulated wear-resistant nickel bronze.

    ●Aluminum alloy:

    1 After shot blasting, special anti-corrosion treatment (maintaining the color of silver-white alloy, and resistant to corrosion by organic solvents such as gasoline and toluene);

    2 After phosphating, spray RAL5010 blue baking varnish;

    Cast iron: spray RAL5010 blue baking paint.

    ●Drive reversibility

    The torque transmission of the input end (worm) at the output of the reducer (worm gear) is the reverse drive of the reducer. The characteristic that the reducer exhibits in the reverse drive is the worm reduction.

    The transmission of the speed machine is reversible. This feature of the selected gearbox must be taken into account during use.

    The transmission reversibility of the reducer is related to the efficiency of the deceleration, corresponding to the static efficiency nS and the dynamic efficiency nd. The reversible characteristics of the transmission of the reducer are described as follows:

    ηS <0.5: Static force is irreversible. That is, when the speed reducer is in a stationary state, the input worm cannot be driven by applying a torque to the output worm wheel, and the reverse drive is self-locking.

    ηS=0. 5-0.55: Low static reversible. That is, when the speed reducer is in the static state, the input worm can be driven by the torque to the output worm wheel, and the input worm is not self-locking. Seven, worm gear reducer

    ● Efficiency

    Efficiency is an important indicator of a salt speed machine, depending on the design and manufacture of the worm and worm gear drive and the friction. Because the reducer has different friction in the running state and in the stationary state

    Sex, so the efficiency of the reducer has dynamic efficiency and static efficiency:

    1 dynamic efficiency nd: transmission efficiency of the reducer under operating conditions (moving friction);

    2 static efficiency nS: 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, nd=ηS.
