How to deal with the oil leakage of NMRV reducer?

2024-10-23

In order to improve efficiency, NMRV worm gear reducers use non-ferrous metals for worm gears and harder steel for worm gears. Due to its sliding friction transmission, high heat is generated during operation, causing differences in thermal expansion between the various parts and seals of the reducer, resulting in gaps on the mating surfaces. The oil becomes thinner due to the increase in temperature, which can easily cause leakage. Damaged seals, ruptured casing, blocked ventilation holes, and high oil levels can all cause oil leakage in NMRV reducers.

When the torque pulsation frequency is low and close to the natural frequency of the equipment system, resonance may occur. Therefore, it is necessary for the equipment system to pay attention to preventing operation near the resonance point. If a PWM frequency converter or a current type and voltage type frequency converter with multiple skills is selected, the output waveform will be greatly improved and high-order harmonics will be greatly reduced, so this question can be greatly improved.

The basic working principle of traditional DC servo motors is exactly the same as that of ordinary DC motors, which rely on the action of armature current and air gap flux to generate electromagnetic torque and make the servo motor rotate. The armature control method is usually used, which adjusts the speed by changing the armature voltage while keeping the excitation voltage constant. The smaller the armature voltage, the lower the rotational speed; When the armature voltage is zero, the motor stops running. Since the armature voltage is zero and the armature current is also zero, the motor does not generate electromagnetic torque and does not experience "self rotation".

1. Full pressure direct start When both the grid capacity and load allow for full voltage direct starting, full voltage direct starting can be considered. The advantages are convenient operation and control, simple maintenance, and relatively economical. Mainly used for starting low-power motors, from the perspective of energy conservation, this method is not suitable for motors larger than 11kw. 2. Self coupling decompression starting The use of multi tap voltage reduction of autotransformers can not only meet the needs of starting different loads, but also obtain greater starting torque. It is a commonly used voltage reduction starting method for starting larger capacity motors. Its biggest advantage is that it has a large starting torque. When the winding tap is at 80%, the starting torque can reach 64% of the direct starting torque. And the starting torque can be adjusted through tapping. It is still widely used today.
