When the RV reducer is working outside, it must be protected from sun protection, anti-collision and rain. RV reducer should be placed on a set or rigid support surface area, and avoid all foreseeable vibrations around. It is best to pre-tighten with a washer. The bolts in the RV gearbox should retain plenty of lubricant and check regularly. This group of reducer is normally a common design, employed when the ambient heat does not surpass + 40 °C. When setting up the pinion equipment at the outcome shaft end of the RV reducer, when the coupling or the pulley is used, the shaft end screw hole pressing technique is adopted. It is strictly forbidden to hammer. RV reducer avoids mixing artificial oil with mineral essential oil. RV reducer can be operated for the first time for 150 hours, and should be replaced after re-lubricating. The oil change interval is approximately 4,000 hours.
Pay attention to the following ideas when installing and installing the apparatus unit
As displayed in Figure 1, the gear unit should be securely mounted on the device to avoid vibration.
2. Check the right rotation direction of the output shaft before assembling the reducer on the mechanical apparatus.
3. When the reducer is kept for an especially long time period (4~6 months), if the oil seal isn’t immersed in the lubricating oil and exposed, remember to replace the essential oil seal. This is since the rubber will stick to the shaft and even lose its elasticity. . Need to fully restore its effectiveness.
As proven in Figure 4, whenever possible, avoid the reducer subjected to sunlight and harsh environments.
5. Place the fan head in the weather duct to ensure that the electric motor cools in the right way.
As shown in Number 6, please contact our technical department if the ambient heat range is below -5 ° C or above 40 ° C.
7, can not paint the color on the rubber parts.
8, the torque is gradually increased after starting, cannot load the utmost load together.
