The installation and debugging of the worm gear box indeed require meticulous operation, with the core being leveling and alignment, proper lubrication, and trial operation monitoring. Especially, attention should be paid to coaxiality control and lubrication management, which are the key to avoiding early failures. Below, I have sorted out specific precautions for you:

1、 Preparation before installation
Environmental requirements: Avoid installation in dusty, humid (relative humidity>85%) or corrosive environments. If unavoidable, a protective cover (IP54 or higher protection level) should be installed.
Box inspection: Check the center distance of the box holes, the perpendicularity of the two hole axes, and other errors to ensure compliance with standards (such as GB/T 10085-2003).
2、 Key points during installation process
Coaxiality control: The coaxiality error between the input shaft and the motor shaft should be ≤ 0.1mm (radial deviation) and ≤ 0.05mm/m (axial deviation).
Lubrication management: Replace the lubricating oil after the first 100 hours of operation, and then replace it every 3000 hours or 6 months (whichever comes first).
Spare parts replacement: During maintenance, original accessories (such as tin bronze ZCuSn10Pb1 for worm gear and 45 # steel quenched worm gear) should be used, and ordinary steel should not be used as a substitute.
3、 Debugging and Verification
No load test run: Run at low speed for 10-15 minutes, check for any abnormal noise or temperature rise (temperature rise at the bearing ≤ 40 ℃).
Load test: Gradually load to rated load, monitor axial play and changes in meshing noise.
Final tightening: Tighten the bolts in diagonal order and mark them with anti loosening marks.
4、 Common problems and solutions
Large axial displacement: It may be due to insufficient pre tightening of the bearing, and the gasket or bearing end cap clamping force needs to be readjusted.
Excessive meshing noise: It may be due to small side clearance or poor lubrication, and the center distance needs to be increased or high viscosity lubricating oil needs to be replaced.
Local heating: It may be due to poor alignment or excessive pre tightening, and the parallelism of the axis needs to be corrected to reduce the pre tightening of the bearing.
5、 Maintenance cycle
First run: Replace the lubricating oil after 100 hours (remove initial wear impurities).
Subsequent maintenance: Replace every 3000 hours or 6 months (whichever comes first).
I hope this information can help you successfully complete the installation and debugging!
