1、 Installation precautions

1. Foundation and Support
   • The reducer must be installed on a stable and horizontal foundation or base to ensure that the oil in the drain tank can be smoothly discharged and the cooling air circulation is smooth. Unreliable foundations can cause vibration and noise, accelerate bearing and gear wear.
   • The installation environment should avoid direct sunlight, rain, and corrosive gases, and the temperature range should be controlled between -5 ℃ and 40 ℃.
2. Alignment and concentricity
   • The concentricity error between the output shaft of the reducer and the drive equipment shaft shall not exceed the compensation amount of the coupling, otherwise it may cause additional torque and bearing damage.
   • During installation, a level should be used to adjust the verticality and levelness to ensure that the axial position meets the requirements.
3. Connection and fastening
   • When connecting the motor to the reducer, it is necessary to ensure that the input shaft is concentric with the output shaft and the flange is parallel. The installation bolts should be gradually tightened diagonally to avoid excessive axial or radial force that may damage the bearings.
   • All fasteners (such as bolts and nuts) need to be fixed with a torque wrench according to the indicated torque to prevent loosening.
4. Protection and Cleaning
   • During the installation process, residual burrs and debris should be removed, and all parts should be cleaned to prevent dust and foreign objects from entering the interior.
   • Transmission components (such as sprockets and gears) should be installed as close as possible to the bearings to reduce axial bending stress.

2、 Precautions for use

1. Load and speed
   • It is strictly prohibited to use beyond the rated load. The input speed of the worm should not exceed 1500r/min, otherwise it may cause equipment overheating or damage.
   • When starting up, gradually apply the load to avoid starting at full load.
2. Oil level and lubrication
   • Before use, check the oil level to the specified position (according to the oil dipstick or oil level gauge), and regularly replace the lubricating oil. After 7-14 days of operation, the new gearbox needs to be replaced with oil, and then every 3 months or regularly according to the working conditions.
   • The selection of lubricating oil must meet the equipment requirements, and different grades of oil must not be mixed. When the ambient temperature is too high or too low, the lubricating oil grade needs to be adjusted.
3. Heat dissipation and ventilation
   • Ensure good ventilation near the motor fan to avoid oil temperature rise due to poor heat dissipation. When the oil temperature exceeds 90 ℃, cooling measures should be taken (such as circulating oil lubrication or adding cooling pipes).
   • Regularly clean the ventilation holes and air filters to prevent blockages from affecting heat dissipation.
4. Brake cooperation (such as matching PRECIMA brake)
   • Regularly check the brake clearance and friction plate wear to ensure responsive braking.
   • Keep the brake and surrounding environment clean to avoid oil and dust affecting the braking effect.

3、 Maintenance precautions

1. Regular inspection and recording
   • Check the oil level, oil temperature, and whether there is any oil leakage every day, and check the tightness of bolts and the quality of lubricating oil every month.
   • Establish maintenance records, including pressure measurement data, filter replacement time, etc., and predict fault trends through data analysis.
2. Key component maintenance
   • bearingRegularly check the lubrication condition and promptly replenish or replace the lubricating oil. When the bearing load is high and the temperature is high, high viscosity lubricating oil should be selected.
   • gearCheck for scratches, bonding, and significant wear on the gear teeth, replace spare parts if necessary, and use them after running in and load testing.
   • sealing elementWhen the gearbox is stored for more than 4-6 months, it is necessary to check whether the oil seal is immersed in lubricating oil to prevent the lip from losing elasticity and causing oil leakage.
3. Shutdown inspection
   • After shutdown, external and internal inspections are required, including lubricating oil level, oil quality, bolt tightening, coupling alignment, etc.
   • Confirm that there is no abnormal noise or jamming during manual turning, and check whether the gear position has changed and whether the gear teeth are damaged.
4. Professional maintenance and selection
   • During maintenance, it is necessary to follow the manufacturer's instruction manual to avoid blind operation. For example, when replacing lubricating oil, it is necessary to release the old oil while it is hot and clean the oil tank with washing oil.
   • When selecting, the appropriate model should be chosen based on specific operating conditions such as load, speed, and ambient temperature to avoid low efficiency or equipment damage.
